Problems solved by technology

In engineering applications, cohesive soil fillers are mostly used, and the strength of cohesive soil is low and the strength decays significantly after being exposed to water.
In addition, due to the large dead weight of the two kinds of fillers, it is easy to cause large vertical settlement and horizontal deformation of the reinforced earth retaining wall, which will affect the use effect of the structure when it is built on soft soil foundation.
These shortcomings affect the popularization and application of reinforced earth retaining walls

Abstract

The invention discloses a geogrid reinforcement lime soil retaining wall and a construction method of the geogrid reinforcement lime soil retaining wall and belongs to the field of fixed buildings. The retaining wall comprises a concrete building block type wall panel, filling materials and a one-way plastic stretching geogrid, wherein the weight percentage of lime in the filling materials is 2 percent to 10 percent, the rest materials are soil, and the concrete building block type wall panel is an air bubble light concrete building block type wall panel. The construction method comprises the following steps that: (1) the substrate treatment is carried out, and in addition, stripped base casting groove positions are dug in advance; (2) concrete stripped bases are cast in situ; and (3) retaining wall construction is carried out. The dead weight of the filling materials can be reduced, the self stability is improved, and the requirement on the foundation carrying capability is reduced; the integral performance of the filling materials is enhanced, and the intensity is improved; the geogrid intensity damage can be reduced; and the material resources are wide, the materials can be obtained from local sources, and the manufacture cost is low.

Description

technical field [0001] The invention relates to a geogrid reinforced lime soil retaining wall and a construction method thereof, belonging to the field of fixed buildings. Background technique [0002] The building used to support all kinds of earth and stone, limit and prevent its deformation, ensure the stability of the supported object, and bear the lateral earth pressure itself is called the retaining wall. Retaining walls are widely used in civil engineering industries such as roads, railways, and water conservancy. [0003] Reinforced soil is a composite soil formed by adding reinforcing materials to the soil. Adding reinforcement materials to the soil can increase the strength of the soil and increase the stability of the soil. At present, the reinforced soil retaining wall is widely used in engineering. Compared with the traditional gravity retaining wall and other structural forms, the reinforced soil retaining wall has the following characteristics: the panels an...
