Safety aids for road construction retaining walls

Abstract

The invention relates to a safety assisting device for a road construction retaining wall, and effectively solves the problems that the safety performance of the existing road construction retaining wall is not enough and a staff has difficulties in cleaning the road construction retaining wall. The safety assisting device is characterized by comprising an arc retaining wall arranged between a road and a mountain slope, a groove is arranged between the retaining wall and the mountain slope, the groove is provided with a lifting plate in a sliding and matching way vertically, a second groove isformed in the retaining wall vertically, a reserve baffle is arranged in the second groove in a sliding and matching way vertically, support columns are fixed at the two ends of the retaining wall, pulling ropes are fixed at the upper ends of the two ends of the lifting plate, a fixed pulley is fixed at the upper end of each support column, the upper ends of the two pulling ropes are respectivelyguided by the different fixed pulleys and then connected with the upper ends of the two ends of the reserve baffle, when earthwork slides to the upper end of the lifting plate, the lifting plate gradually sinks but the reserve baffle gradually ascends; the safety assisting device is ingenious in structure and strong in practicality, and the risk of landslip of the mountain slope and the risk of slipping soil to the road are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a safety auxiliary device for road construction retaining walls. Background technique [0002] The so-called retaining wall refers to the structure that supports the subgrade filling or hillside soil and prevents the deformation and instability of the filling or soil. In the cross section of the retaining wall, the part that is in direct contact with the supported soil is called the back of the wall. , the part opposite to the back of the wall and facing the air is called the wall surface, the part directly in contact with the foundation is called the base, the top surface of the wall opposite to the base is called the top of the wall, the front end of the base is called the wall toe, and the part of the base is called the wall toe. The rear end is called the wall heel, which can be divided into three types: rigid retaining wall, flexible retaining wall and temporary su...

AI Technical Summary

Problems solved by technology

[0010] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a safety auxiliary device for road construction retaining walls, which effectively solves the insufficient safety performance of the existing road construction retaining walls, and cannot effectively solve the problem that the soil at the upper end of the hillside falls to the ground. Roads and hillsides in rainy days are prone to landslides and collapses. Once they occur, they will have a great impact on road driving, and they are extremely dangerous. It is difficult for road maintenance staff to clean up.
