Two-way anchorage plate retaining wall and construction method thereof

Abstract

The invention provides a two-way anchorage plate retaining wall and a construction method of the retaining wall. According to specific construction of the two-way anchorage plate retaining wall, firstly, a construction site is leveled, and anchorage plates and pull rods are prefabricated; according to a construction drawing, a retaining wall foundation and rib columns are constructed, and according to construction design requirements, retaining plates are mounted layer by layer, and then filling is carried out; when the landfill height of the filled earth reaches the design mounting height of an anchorage component of each layer, an anchorage body is constructed at the position, close to the rear edge, of the filling layer or in the original slope behind the filling layer, and positive and reverse anchorage plate mounting grooves and positive and reverse pull rod grooves are excavated in the filled earth on the layer; positive and reverse anchorage plates and positive and reverse pull rods are mounted; the front end of the positive pull rod is connected with the rib columns, and the rear end of the positive pull rod is connected with the positive anchorage plate; and the front end of the reverse pull rod is connected with the reverse anchorage plate, and the rear end of the reverse pull rod is fixed to the upper end of the anchorage body. The stability of the retaining wall can be improved, the possibility of retaining wall damage is reduced, and an interface face between the filled earth and the original slope is reinforced.

Description

technical field [0001] The patent of the invention relates to the field of soil retaining structure reinforcement, specifically a two-way anchor plate retaining wall that adds a reverse anchor plate system to the rear edge of the existing anchor plate retaining wall to improve the safety of the retaining structure and its construction method. Background technique [0002] The anchor plate structure is a new type of retaining structure, which is currently used in various projects such as road abutments, slope retaining, and port revetment. The traditional anchor plate retaining wall is a whole composed of wall surface, tie rod, anchor plate and filling soil. The anchor plate is placed on the rear edge of the potential sliding surface, and the earth pressure acting on the wall depends on the pulling force of the tie rod and the pull-out force of the anchor plate to maintain the stability of the retaining wall. [0003] In the traditional anchor plate retaining wall, the anch...

AI Technical Summary

Problems solved by technology

[0003] In the traditional anchor plate retaining wall, the anchor plate provides the resistance force, and the tie rod bears the main tension force. When a local tie rod breaks, the pull force of the adjacent tie rods will be increased, which will drive the chain breakage of the tie rods, making the retaining wall very easy Local damage occurs

In addition, due to the difference in the nature of the filler and the original topographical soil, and the quality of edge rolling is difficult to guarantee, the interface will loosen due to earthquakes or soaking in rain, resulting in overall failure of the interface of the retaining wall
