Question 1: What does it mean to control waterlogging? to control waterlogging [zhì lào]
To fight against waterlogging; to control waterlogging; to relieve waterlogging and provide disaster relief
涝[lào]
p>
Excessive rain and crops being flooded, which is the opposite of "drought": drought resistance and prevention~. ~ Disaster.
Water accumulated in fields or low-lying areas due to excessive rain: drainage ~ disaster relief.
Question 2: In water conservancy and hydropower projects, what does “controlling waterlogging” mean? Control floods and other water disasters
Question 3: What does low head mean in water conservancy and hydropower projects? Water head is the water level difference between the upstream and downstream of hydraulic pouring materials. Low water head means that the water head difference is small, and the unit potential energy of the water body that can be stored is small.
Usually refers to hydropower stations with water heads below 40m. Sometimes a hydropower station with a water head of only 2 to 4 m is called an extremely low head hydropower station. Most low-head hydropower stations are built in the middle and lower reaches of the river with gentle slopes. They often have favorable conditions such as convenient external transportation, good construction conditions, close to power centers, and easier project implementation. They also often have channelized rivers for the development of shipping and water diversion. Benefits of irrigation. From the perspective of power generation operation characteristics, there are reservoirs with low capacity to regulate runoff, and most of them are run-of-river power stations. If there is no large-scale reservoir regulation upstream, the output process changes with changes in natural flow, and the stability is poor.
Question 4: How to calculate the flood control area in water conservancy and hydropower? Large and medium-sized water conservancy and hydropower projects refer to water conservancy and hydropower projects whose scale reaches the national standards. Different projects have different classification standards. For example, reservoir projects are divided by reservoir storage capacity. Large reservoirs with a total storage capacity of more than 100 million cubic meters are classified as medium-sized reservoirs with a total storage capacity of less than 100 million cubic meters and more than 10 million cubic meters. Hydropower projects are classified by reservoir storage capacity. The total installed capacity of hydropower stations is divided...
Question 5: What is water conservancy work? It seems that you are deliberately looking for trouble. What do you mean by water conservancy work? It ranges from water conservancy projects to small sewer repairs. It is related to water conservancy. All activities can be called water conservancy work, and water conservancy work is related to people's livelihood.
Question 6: How do you understand the cross-sectional view of the water conservancy project river drawing? The second-level water conservancy and hydropower general contracting enterprise: can undertake the construction of water conservancy and hydropower projects below medium-sized projects and hydraulic buildings below level 3 of the building level. However, the scale of the following projects is limited to the following range: dam height is less than 70 meters, total installed capacity of hydropower stations is less than 150MW, hydraulic tunnel diameter is less than 8 meters (or other types with equal cross-sectional area) and length is less than 1,000 meters, embankment level 2 the following. Note: Water conservancy and hydropower projects refer to various types of projects (including supporting and ancillary projects) for the purpose of flood control, irrigation, power generation, water supply, waterlogging control, water environment management, etc. The main project contents include: hydraulic structures (dams, embankments , sluices, spillways, hydraulic tunnels, culverts and culverts, water intake buildings, river regulation buildings, canal system buildings, navigation, wood crossing, fish crossing buildings, foundation treatment) construction, hydropower station construction, water pumping station construction, hydraulic Mechanical installation, hydraulic metal structure manufacturing and installation, electrical equipment installation, automated information systems, environmental protection project construction, soil and water conservation project construction, land consolidation project construction, and roads, bridges, communications, hydrology, and well sinking related to flood control and drought relief The construction of other projects, the construction of management buildings and ancillary projects related to the above projects, etc., please refer to the "Technical Terminology Standards for Water Conservancy and Hydropower Engineering" (SL26-2012) for details.
Question 7: Read "Writing Essays No Longer Relying on Dad" "Mom" Reflections 1. Talking about the writing of after-reading feelings (1) What is after-reading feelings? After reading an article or a book, write down the feelings, experiences, education, enlightenment, etc. you have received. The written article is called "after-reading feelings" ". (2) What to read? The famous American educationist Jane Hailey said: "Reading literary works to children for even 10 minutes every day is very beneficial to their growth." What to read? The question seems not complicated. , but quite difficult to answer.
Because, if the words are too general, such as "opening the book is beneficial," you can read anything, and the meaning is naturally good, but it is not practical; if you turn to the other extreme and make it too specific, the difficulty will be, in a word, Say "read well". This is like an ambiguous statement that is almost cliche, but it has to be said, because if you focus on the top, you will only get the middle. If you focus on the bottom, you will naturally only get the bottom. It is said that when Wang Xizhi learned calligraphy, he initially took Mrs. Wei as his teacher, but he was never satisfied. When he went north, he saw the famous tablets of Han and Wei Dynasties, and then he got married. In fact, Mrs. Wei was also a "shang". Wang Xizhi was not satisfied because there was still a "shang". Learning composition is a principle, to put it to the extreme, if the article you recite does not make sense or is full of holes, even if you learn it well, it will still be unreasonable or full of holes. To be good, you must take the best approach, preferably the best. Ancient writers in the past, such as Gui Youguang of the Ming Dynasty, worked hard on "Historical Records" throughout their lives. This was because they followed the method from the top, so their attainments could exceed those of ordinary people. Here are just examples to illustrate that reading a good article is a necessary or even sufficient condition for writing well. At this point, students must ask, how to calculate it? This is another question that is difficult to answer in one sentence. Du Fu said: "Articles are about things through the ages, and you know the gains and losses carefully." This means that you don't really believe in the comments of the world. But regardless of whether the author agrees or not, since it is shown to the world, the world will always comment; and comments are often in the opinion of the beholder and the wise. Just like Tao Yuanming's poems, Zhong Rong, who wrote "Shi Pin", was not highly regarded, but became unattainable in the Tang and Song Dynasties. In this way, can't the articles be distinguished? Of course not. For example, Zhuang, Lie, Shi, Li, Du, Han, and Liu in the Han and Tang dynasties in ancient times, and Ou, Zeng, and Sansu in the Song dynasty, are almost all admitted to be generous in terms of their works and writers. In this way, the criteria for evaluation are as mentioned before. On the one hand, the content is good, profound, appropriate, fresh, and can make people gain insights. On the other hand, the expression is good, precise, concise, and vivid, so that people can clearly understand and enjoy the language. Beautiful, I won’t go into details here. The so-called good reading means reading works that can be learned in both content and expression. Our compositions are written in modern languages, so of course we mainly read modern works, and most of these have not yet been written into the history of literature. Why? The method is: (1) Of course, it is best to discern it yourself. (2) Turn to popular comments. This is often seen in various forms of writing, introductions in magazines and newspapers, introductions to books, selected books (including textbooks), and even advertisements from publishers, etc.; (3) Ask for advice from the knowledgeable. There are many knowledgeable people. Chinese teachers and the older generation of scholars are all knowledgeable. If you don’t know something, you can ask them. When choosing reading materials, after being able to distinguish between good and bad ones, there is also the issue of determining the categories, that is, which types of works should be read or read more, and which types of works should be read less or even not at all. Of course, you must first read the works in the Chinese textbook and the prescribed extracurricular readings. This is not enough. If you want to read more to learn composition, you should consider the following situations when choosing reading materials. (1) The style must be commonly used, or easily transferred to compositions. For example, prose in a broad sense (including narrative-based and reasoning-based) is better than poetry and novels. The language of poetry has its own characteristics. For example, sometimes you can be deliberately obscure and often disconnected between two sentences. If you learn this, it will do more harm than good to your composition. Novels have a lot of dialogue and descriptions. Some young people read more novels and less other genres. When they pick up a pen, they want to describe characters and scenery. As for remembering trivial matters and reasoning, even if they are very simple, they don’t know how to write. This is not achieved. Help but be disturbed by it. My experience is that in this regard, sometimes it is unavoidable to pinch your scalp. For example, when reading the works of Lu Xun, many young people will feel that novels are more interesting and easier to read than essays. However, when it comes to studying composition, I still advise you to use your best efforts in essays. (2) It is better to read more works from your own country; when reading translated works, it is best to choose ones whose text style is close to Chinese. The reason is very simple. When we write compositions, the sentences must be Chinese, not foreign. (3) Don’t just do it for fun and save effort. In this regard, I would like to give an extreme example. As we all know, there are many teenagers and some middle-aged people who are enthusiastic about reading. They even keep reading in the car, but they always read little books.
Of course, it’s not a bad thing to read little books, but if you always read this kind of books instead of others, if you want to make progress in your composition...gt；gt;
Question 8: Wife says she has decided Things will not change. We have two children. You will live with your parents' family, but what the hell? Hahaha, my wife went back to her parents' house to play for a few days. I just want you to pick her up and take her home, ask her to step down, say some nice words, and tease her. If your wife is happy and she treats you well, you should also cherish her! Don't be too demanding, learn to be tolerant between husband and wife, and call to say hello! Also buy some things for your parents-in-law, hoping that they will also help you and say a few kind words.
Question 9: What principles should be followed in the assessment of gross motor function 1 The emergence of urban water environment planning
Since the early 1990s, the disorderly construction activities caused by urban expansion have Bringing more and more serious harm to the water environment. After entering the 21st century, the country has elevated the protection of water environment to an extremely important position. After 2000, the country has officially launched a new water resources protection plan. On the other hand, with the development of urban socio-economics, the city's demand for water resources is no longer limited to water supply resources for living and production, but also requires water landscape resources to meet people's needs for the natural environment. Under the guidance of this dual consciousness, urban sewage treatment projects and extensive urban waterfront landscape planning discussions and construction have become representatives of today's urban water environment protection and utilization activities in the past five years. Cities such as Shanghai, Wuhan, Chongqing, and Guangzhou have successively compiled Projects related to urban water environment planning, therefore, as a plan to guide the construction of urban water environment - "Urban Water Environment Planning" will gradually attract attention in the planning industry.
2 Objects of urban water environment planning
2.1 Water environment components
2.1.1 Understanding of resources
First of all, clarify the relationship with water The concept of water resources is closely related to the environment. The concept of water resources in a narrow sense is that natural water can be continuously renewed and can meet the basic water needs for the survival and development of human society, including domestic water, industrial water and agricultural water. The connotation of water resources in a broad sense is everything with utilization value, including water from various sources or different forms, which all belong to the category of water resources. Therefore, water resources are divided into water supply resources, water shipping resources, aquaculture resources, water energy resources, and water ecology. Landscape resources, etc.
2.1.2 Environmental components
Water environment refers to the space surrounding people and water bodies that can directly or indirectly affect human life and development. Its normal functions include various natural factors and related factors. the totality of social factors. According to this concept, it can also be said that the water environment reflects the various water resources available to the water body and the ability to prevent water disasters, including the ability of natural formation and artificial transformation, that is, the natural water environment and the social water environment. The natural water environment includes four factors:
(1) Runoff amount - the amount of water that can be supplemented by runoff from natural water bodies reflects the water supply resource capacity available for social use;
(2) Water ecology - the natural conditions of water quality and the natural ability to restore water quality;
(3) Water space - the regional space involved in continuous water bodies and the depth of water body accumulation under natural terrain conditions, It reflects the ability of water bodies to serve as conditions for shipping, breeding, and entertainment;
(4) Water energy - the energy generated by water bodies due to the movement of natural terrain reflects the ability of energy that can be utilized by society.
Social water environment factors include two aspects:
(1) Water security - mainly reflects the society's ability to manage water bodies and prevent disasters, including preventing floods and eliminating waterlogging;
(2) Water landscape - the landscape formed by water and shoreline natural landforms and cultural facilities, is the ability to reflect the urban waterfront environment and cultural connotation.
2.2 Water environment planning objects
According to the theory of "Environmental Planning", water environment planning is the overall arrangement and design of water environment protection goals and measures within a certain period of time , achieves the goal of sustainable social development by protecting, improving, and utilizing various types of water resources to meet human production activities. The basic object of water environment planning is to protect and utilize the above-mentioned six types of natural and social water environment factors, namely runoff utilization, water ecological protection, water space utilization, water energy utilization, water safety control, and water landscape utilization.
Water environment planning is generally divided into basin water environment planning, regional water environment planning and urban water environment planning according to the planning scope. Different planning scopes have different choices for the six basic objects.
2.2.1 Water environment planning objects
Basin water environment planning is mainly the regional management of river basins and comprehensive utilization of river planning. According to the river basin planning preparation standards, the objects of river basin water environment planning include water resources system planning (runoff utilization), water pollution control (water ecological protection), river flood control and waterlogging planning (water safety control), shipping and breeding planning ( Water space utilization), hydropower planning (water energy utilization), etc.
2.2.2 Water environment planning objects
Regional water environment planning is mainly the planning of regional management and comprehensive utilization of river tributaries within the administrative region (provincial area), including small rivers, lakes, reservoirs, etc. water system. Planning objects should include water distribution for cities and agriculture in the region (runoff utilization), flood control in water systems connected to outer rivers and drainage of inland rivers and lakes (water safety control), water environment protection of planned water systems (water pollution control), and fishery breeding in water bodies. (Water space utilization) and other contents.
2.2.3 Water environment planning objects
