Problems solved by technology

This kind of structure has a large number of masonry, high cost, and unattractive appearance. Especially in the era when stone resources and labor resources are becoming more and more tense, in order to make the retaining wall economical and reduce costs, people try to add it to the backfill of the wall. An appropriate amount of tensile material can improve the shear resistance of the soil and achieve the purpose of forming the entire reinforced soil body to retain the soil, that is, the so-called reinforced soil retaining wall

Embodiment Construction

[0020] The steps of lightweight retaining wall of the present invention and construction method thereof are as follows:

[0021] (1) Prepare the foundation: Excavate the foundation groove at the position where the retaining wall needs to be installed, tamp the original soil, lay a graded crushed stone cushion on the foundation groove, and then build a concrete or crushed stone foundation on the crushed stone cushion to form For the foundation 1 shown in Figure 1, an expansion joint is set every 10m on the foundation 1, and materials such as asphalt board, cork board or asphalt lint are used as joint fillers for the expansion joint;

[0022] (2) The first layer of wall panel 2 is installed on the foundation 1: on the foundation 1 prepared in the above step (1), the cement mortar of about 2 cm is first placed to form a cement mortar layer 11, so that the surface of the cement mortar layer 11 is equal to the horizontal plane. Parallel, install the first layer of wall panel 2 on t...

Abstract

The present invention discloses a light retaining wall and its construction method. Said method includes the following steps: firstly, building foundation, laying cement mortar on the foundation and making cement mortar surface be parallel to the horizontal plane, inserting first layer of wall panel into the cement mortar and making the plane of wall panel be perpendicular to the cement mortar surface, after the cement mortar is solidified and the wall panel and foundation are connected into one body, after the wall panel laying first layer of light filling material, then laying reinforcing bar on the compacted light filling material, making one end of reinforcing bar be firmly connected with wall panel and making its another end be inserted into light filling material, then successively mounting second layer of wall panel, laying second layer of filling material and setting reinforcing bar according to the above-mentioned steps until the predefined height is reached so as to obtain the light retaining wall.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering and construction, and in particular relates to a retaining wall and a construction method for the retaining wall. Background technique [0002] The most common structure of the retaining structure is the retaining wall, and the function of the retaining wall is to retain soil. The gravity retaining wall relies on the weight of the wall itself to balance the lateral pressure of the soil behind the wall. The wall material is made of block stones with cement mortar or reinforced concrete. This structure is widely used in various revetments and embankments. , bridgehead and pier wing walls. The mortar block stone retaining wall or the reinforced concrete retaining wall is bulky, has a lot of consumable materials, and is heavy. It has high requirements on the bearing capacity of the foundation and has a single landscape effect. This kind of structure has a large number of masonry, hi...
