Light self-anchored precast reinforced concrete retaining wall and construction method thereof

Abstract

The invention discloses a light self-anchored precast reinforced concrete retaining wall and a construction method thereof. The light self-anchored precast reinforced concrete retaining wall comprises wall bodies oppositely positioned on two sides of a road, wherein the wall bodies are of an upright design; the bottoms of the wall bodies are supported by concrete foundations and are connected by virtue of multiple anchor bars. The process of the construction method comprises the following steps: splicing plates; mounting the anchor bars; and filling back and compacting. Precast elements are used on a large scale, so that the construction period is shortened, and the engineering quality is ensured. The construction method is simple in structure and convenient in construction, free from large machines for construction, easy to be maintained, and applicable to road construction such as highway construction, municipal bridge construction and culvert construction.

Description

technical field [0001] The invention relates to the technical field of highway municipal construction, in particular to a light self-anchored prefabricated reinforced concrete retaining wall and a construction method. Background technique [0002] At present, my country's infrastructure construction is booming, and the period of rapid development of highways, railways, and municipal services has arrived. In the construction of civil engineering, the safety protection and stability of slopes have always been the focus of attention. [0003] In practical engineering, retaining walls are usually used for slope protection. Retaining walls are buildings used to support natural slopes or artificial fill slopes to keep the soil stable. Its function is mainly to shrink the slope foot of the embankment, reduce the amount of filling and the occupied area, and ensure the stability of the embankment; prevent the embankment along the river from shrinking the river bed, and prevent the ...

AI Technical Summary

Problems solved by technology

[0006] However, in actual use, there are also many problems in the reinforced soil retaining wall. For example, when the filling height is greater than 10m, the length of the reinforcement of the retaining wall usually reaches 15m. If the width of the roadbed is less than 15m, the roadbed The ties of the retaining walls on both sides will overlap each other, resulting in waste of materials, and even because the width of the roadbed is too small, it is not conducive to the laying of ties

In addition, the tie bars provide anchoring force through friction with the backfill soil, so the surface area and friction performance of the tie bars need to be increased, and there are more restrictions on the form and amount of the tie bars

Moreover, the mechanism of action between the reinforcement and the soil is still not completely clear, which is not conducive to the accurate calculation and evaluation of the stability of the retaining wall.
