Saving type gravity assembly type retaining wall

Abstract

The invention relates to a saving type gravity assembly type retaining wall, and aims to provide a single module which is assembled on site to form an integral retaining wall. The method specifically comprises the steps that molds of the modules are manufactured in a factory, then steel bars of the transverse plates, the vertical plates and the bottom plates are bound, the modules are taken out after concrete pouring and hardening are conducted, then the modules are transported to a needed retaining wall construction site through a truck, the modules are assembled on site, and after each layer is assembled, the cavities of the modules are filled with stones and soil; and then the modules on the upper layer are assembled, the cavities of the modules on the upper layer are filled with stones and soil, the modules on all the layers need to be in lap joint in a staggered joint mode as shown in the figure 1 and the figure 2, and the modules on all the layers are assembled repeatedly till the designed height is achieved, so that the required retaining wall is obtained.

Description

Technical Field

[0001] This invention patent relates to the field of engineering retaining wall technology, specifically a reinforced concrete module for a prefabricated retaining wall. Background Technology

[0002] With the development of prefabricated buildings, municipal engineering, highways and other engineering structures, the intensity of manual labor is reduced, the amount of engineering materials used is reduced, the consumption of formwork on the construction site is reduced, and retaining wall projects can be completed efficiently and quickly. In addition, the soil in the grid trench can be filled and small plants can be planted in the soil. It is an important way to build sponge cities and ecological cities with retaining walls. Summary of the Invention

[0003] The purpose of this invention is to provide a single-module structure that, when assembled on-site, forms a complete retaining wall. The specific method is as follows: First, molds for the modules are made in a factory (each layer has two types: long modules and short modules). Then, the reinforcing bars for the horizontal, vertical, and bottom slabs are tied, concrete is poured, and after hardening, the modules are removed and transported by truck to the required retaining wall construction site. The modules are then assembled on-site. After each layer is assembled, the cavity of the module is filled with gravel and soil; then, the next layer of modules is assembled, and its cavity is filled with gravel and soil. Each layer of modules must be staggered and overlapped. Figure 1 , Figure 2 As shown, this assembly process is repeated until the wall reaches the designed height and forms the required retaining wall. Attached Figure Description
