What is the scope of site leveling in road engineering construction? In addition, I have a question now, that is, is culvert construction carried out at the same time as earthwork excavation and filling? Site leveling is to transform the natural ground into the design plane required by the project. Because the whole site has both excavation and filling, and the shape of excavation and filling is often irregular, the grid method is generally used to calculate and solve it in blocks.

Before leveling the site, all preparations should be made, such as removing all obstacles on the ground and underground; Drainage of groundwater; Laying temporary roads, etc.

The principle of selecting site design elevation is:

(1) on the premise of meeting the requirements of general layout design and coordinating with the elevation of off-site engineering facilities, consider the balance of excavation and filling to achieve the balance of excavation and filling;

(2) If the excavation is less than the fill, the source of earthwork should be considered; If the excavation is larger than the fill, the spoil ground should be considered; (3) The design elevation of the site should be higher than the highest flood level in this area, and the highest underground water level of the site should be lower than the freezing depth of soil in severe cold areas.

Generally speaking, whether culvert construction and earthwork excavation and filling can be carried out at the same time can only be carried out at the same time if the construction does not conflict. But you have to be so horizontal.
