Why do you put one or several iron plates at the door of almost every construction site? What's the point?

Because there are often big trucks coming in and out at the entrance of the construction site, some earth and stone and steel will be put inside, which makes the whole truck heavier. If you don't put one or several iron plates at the door, the cart will crush the road at the door, resulting in potholes on the road. In addition, in fact, iron plates can also be used as pavements to protect some underground facilities, such as water pipes or other pipelines. In addition, steel plates are very strong and easy to clean, making them the best choice for many construction sites.

I believe many people have seen such a situation. When passing by a construction site, they will find many iron plates in front of the construction site. These iron plates are put together seamlessly and will not show the ground at the door. When the cart runs over the iron plate, if there is a creaking sound, it means that there is something wrong with the pavement under the iron plate and it needs to be repaired in time. If it is only a cement road, it may go deeper and deeper, and people nearby often see it, so it may not notice it, resulting in the destruction of the road surface.

Laying iron plates can also protect the road surface. After all, there may be several tons of carts with all kinds of sundries on them, which will do great damage to the road surface. The strength of the iron plate is relatively large, which can bear the weight of large trucks and will not let them crush the road. In addition, the large trucks used in the construction site are all gravel or construction waste, which may fall off when walking. If it falls on the road, it is difficult to clean it, and if it falls on the iron plate, it is easy to sweep it off. This is the wisdom of the working people and the experience gained in daily work. Ordinary people may not understand it, but insiders can see the doorway.

And the entrance to the construction site is muddy. If you don't lay iron plates, people who come in and out will probably step on the mud and get their shoes dirty. After the iron plate is laid, people can enter the construction site from the iron plate to maintain hygiene.
