A construction method of municipal soft soil roadbed

Abstract

The invention discloses a construction method of a municipal soft soil roadbed, wherein the roadbed comprises: a road base and an anti-collapse edge, a sand layer is arranged on the road base, a supporting layer is arranged above the sand layer, and a water-conducting layer is arranged on the supporting layer An anti-collapse layer is arranged on the water-guiding layer, a pavement layer is arranged on the anti-collapse layer, a waterproof layer is arranged above the pavement layer, and anti-collapse edges are arranged on both sides of the subgrade. The construction method of a municipal soft soil subgrade described in the present invention can effectively prevent the subgrade from collapsing on both sides after being rolled and used by setting anti-collapse edges on the outside of the subgrade, and the sand layer The supporting layer is set on the ground, which can greatly improve the supporting performance of the entire subgrade, improve its safety in use, and prolong its service life. The setting of the water-conducting layer and waterproof layer can effectively improve the water-conducting effect and waterproof performance of the subgrade. , The setting of the anti-collapse layer can effectively limit the subgrade to a certain extent, avoid its collapse, and greatly improve the stability of its structure and the safety of use.

Description

technical field [0001] The invention belongs to the technical field of municipal construction, in particular to a construction method of municipal soft soil roadbed. Background technique [0002] With the rapid development of social economy, people's living standards and quality of life are constantly improving, and the requirements for the surrounding environment are also getting higher and higher. The roadbed is a road for the majority of people. With the development of the automobile and vehicle transportation industry, the weight and pressure that the road can carry has greatly increased, not to mention that there are some bean dregs projects, which are more prone to road sinking or It is the collapse problem, and many roads are made of concrete or directly asphalt, and there is no support layer below them. After a period of use, there will still be problems with support and bearing capacity. SUMMARY OF THE INVENTION [0003] Purpose of the invention: In order to over...

AI Technical Summary

Problems solved by technology

The roadbed is a road that provides traffic for the general public. With the development of the automobile and vehicle transportation industry, the weight and pressure that the road can carry has greatly increased. What's more, there are some bean dregs projects, which are more prone to road subsidence or It is a problem of collapse, and many roads are made of concrete or directly asphalt, and there is no support layer underneath, so there will still be problems with support and load-bearing capacity after a period of use
