Description

A New Combined Reinforced Soil Retaining Wall Structure

technical field

The utility model relates to a civil engineering structure, in particular to a novel combined reinforced earth retaining wall structure.

Background technique

Reinforced earth retaining wall, as a light retaining structure, has been widely used in the field of civil engineering. In recent years, reinforced earth retaining walls with face panels have been gradually applied, and there are two main types—block reinforced earth retaining walls and integral reinforced earth retaining walls.

Integral reinforced earth retaining wall, the overall rigidity of the panel is large, the deformation of the wall is small, and the structural stability is good. However, the on-site pouring process is complicated, and the concrete formwork is difficult and expensive. The block style of the separated reinforced earth retaining wall panel is changeable, the structure is beautiful, the production is prefabricated, the construction is rapid, the construction period can be shortened, and the construction cost can be significantly reduced. From the perspective of rapid construction and economy, the separate retaining wall has obvious advantages.

However, the structure of the conventional separated reinforced earth retaining wall is complex, the formwork is not suitable for making, the self-stability of the blocks is poor, and the seismic performance is weak.

Utility model content

The purpose of this utility model is to provide a novel combined reinforced earth retaining wall structure in order to solve the above problems.

The utility model realizes above-mentioned purpose through following technical scheme:

The utility model comprises prefabricated blocks, steel mesh, suffix angle steel, vertically connected steel bars and longitudinally connected steel bars. The longitudinal grooves and the transverse grooves are distributed in a T-shape, the underside of the prefabricated blocks is provided with protrusions matching the longitudinal grooves, and the upper and lower sides of the prefabricated blocks are provided with two through circles. holes, there are multiple prefabricated blocks, two adjacent prefabricated blocks up and down are connected to the bumps through longitudinal grooves, and the longitudinal connecting steel bars are located between the longitudinal grooves and the bumps, so The reinforcement mesh is welded and connected to the longitudinal connection reinforcement through the transverse groove, the vertical connection reinforcement is placed in the through hole and poured with cement mortar, and the suffix angle steel is arranged at the other end of the reinforcement mesh.

Prefabricated blocks are made through molds, which can be manufactured in a factory and assembled on site. The block structure is simple, the production efficiency is high, and it can be produced in batches. It is beneficial to save costs and shorten the construction period. The prefabricated blocks are connected together through the vertical connecting steel bars in the two through holes and the poured cement mortar to form an integral structure. The connection between the blocks is more stable, which is beneficial to control the deformation of the reinforced earth retaining wall. Improve overall integrity. The reinforcement mesh and the suffix angle steel are welded and connected, the reinforcement body has good integrity, and the suffix angle steel is anchored into the filler, which enhances the stability of the wall.

The beneficial effects of the utility model are:

The utility model is a new combined reinforced earth retaining wall structure. Compared with the prior art, the utility model has a reasonable and reliable structural design, economical and fast prefabricated blocks, and the overall structure is connected. The construction is simple, fast and operable. Strong, stable and safe structure, it is an economical, safe and fast and effective combined reinforced earth retaining wall structure, which has the value of popularization and use.
