Settlement prevention construction method for highway

Abstract

The invention discloses a settlement prevention construction method for a highway. The method comprises the following steps of downwards digging earthwork with a certain depth at a roadbed elevation,and packing a reinforcing material; vertically penetrating a stone column through the reinforcing material and enabling the stone colume to go deep into the ground, and exposing a part of the stone column; carrying out dynamic compaction and leveling on the reinforcing material; enabling a waterproof film to penetrate through the exposed part of the stone column and laying the waterproof film on the reinforcing material after dynamic compaction; laying a woven reinforcing mesh on the waterproof film to be tightly connected to the stone column; pouring concrete at the reinforcing mesh and submerging the stone column, and maintaining the poured concrete; enabling kerbs to go deep into two sides of the pavement; and laying stones on the two sides of the pavement. According to the settlement prevention construction method for the highway, the waterproof film is laid at the deep roadbed, so that the erosion of rainwater on the deep roadbed is avoided, and thus sedimentation is avoided; andthe stones are arranged, so that the erosion of the rainwater to the roadbed is reduced, and meanwhile, the vibration of the pavement is reduced, and thus the pavement can be used for a long time.

Description

technical field [0001] The invention relates to the field of road construction, in particular to a road settlement prevention construction method. Background technique [0002] The literal meaning of highway is that public roads, public transportation roads, automobiles, bicycles, rickshaws, horse-drawn carriages and many other means of transportation and pedestrians can walk. Of course, different roads have different restrictions. [0003] Although bridgehead jumping at both ends of highway structures has become a common phenomenon, if the practice of highway construction projects can really attract great attention to action, or can carry out targeted research and come up with a design plan, the two ends of the highway structure Not many bridgehead jumps have been effectively prevented, and some people even simply think that bridgehead jumping is only a problem of technological quality in construction, and it is normalized. The basic design scheme cannot be specifically des...

[0003] Although bridgehead jumping at both ends of highway structures has become a common phenomenon, if the practice of highway construction projects can really attract great attention to action, or can carry out targeted research and come up with a design plan, the two ends of the highway structure Not many bridgehead jumps have been effectively prevented, and some people even simply think that bridgehead jumping is only a problem of technological quality in construction, and it is normalized. The basic design scheme cannot be specifically designed. Lay hidden

[0004] However, in the prior art, the subgrade is only compacted and the pavement is laid, which also causes long-term rainwater to penetrate into the subgrade and cause settlement.
