Abstract

The invention discloses an anti-softening highway roadbed reinforcing structure. The structure comprises a bottom layer with anchoring rods in the surface; a reinforcing layer which comprises a reinforcing net and a cement mortar layer formed by pouring cement mortar on the reinforcing net; an anti-softening layer which comprises a fixed grid net erected on the reinforcing layer, a composite waterfiltering layer filled in grids of the fixed grid net, a water outlet pipe and a supporting grid buckled on the fixed grid net; and a pavement layer which is arranged above the supporting grid. The composite water filtering layer consists of a water guide block, a water filtering layer and a sponge layer in sequence from bottom to top; the water outlet pipe comprises branch water outlet pipes connected to the first water filtering holes and a main water outlet pipe for communicating the branch water outlet pipes; and the supporting grid is connected with the anchor rods through the containinggrooves and connected with the fixed grid net through the lock catches. Through roadbed construction of a multi-layer structure, the strength of the roadbed is improved, meanwhile, good drainage performance is achieved, roadbed softening is prevented, and the service life of the roadbed is prolonged.

Description

technical field

[0001] The invention relates to the technical field of road construction, in particular to an anti-softening highway subgrade reinforcement structure. Background technique

[0002] Subgrade refers to the belt-shaped structure built according to the location of the route and certain technical requirements as the foundation of the road surface. It is the foundation of railways and highways. The subgrade is a linear structure built with soil or stone. With development, the number of roads is also increasing. However, the roadbed is the foundation of the pavement structure, and the quality of the roadbed directly affects the quality of the entire road. However, the roads in some areas must pass through some paddy fields, low-lying valleys and ponds, etc. These The local land is mainly soft soil layer. Many road constructions have to be built on soft soil layer. In addition, there are also soft soil layers in China's coastal areas. The soft soil layer is character...
