Embodiment Construction

[0025] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings.

[0026] refer to figure 1 and Figure 7 , an assembled gravity retaining wall structure of the present invention includes a foundation 20 and a gravity retaining wall body located thereon. The gravity retaining wall is composed of a prefabricated wall and backfill material 40 filled in its inner cavity. The prefabricated wall is vertically assembled by multi-layer assembled units, and each layer of assembled units is included in the The skeleton boards 10 arranged at intervals in the line direction and the soil retaining plates 20 arranged at intervals in the vertical line direction are connected by slots to form a continuous box body. Two adjacent layers of assembled units are connected through the draw-in grooves on their skeleton plates 10 and soil retaining plates 20 , and the bottom of the lowermost assembled unit is fixedly connected...

Abstract

The invention discloses an assembly gravity type retaining wall structure and a construction method thereof. The technical problems that a traditional gravity type retaining wall is large in structuresize, long in cast-in-place and maintenance time, and construction quality cannot guarantee are solved, and the requirement for construction of railway subgrade engineering in a plateau mountainous area is met. The structure involves a foundation and a gravity type retaining wall body located on the foundation, the gravity type retaining wall body is composed of an assembly type wall body and a backfill material filling an inner cavity of the assembly type wall body, the assembly type wall body is formed by vertically assembling a multiple layers of splicing unit, each layer of splicing unitcomprises framework plates which are arranged at intervals in the line direction and soil retaining plates which are front-back arranged at intervals in the vertical line direction, the framework plates and the soil retaining plates are connected to form a continuous box body through clamping grooves, the every two adjacent layers of splicing units are connected through the clamping grooves in theframework plates and the soil retaining plates, and the bottom of the lowermost splicing unit is fixedly connected with the foundation.

Description

technical field [0001] The invention relates to a slope gravity retaining wall structure, and is particularly suitable for assembling a gravity retaining wall structure in a railway or road subgrade section. [0002] technical background [0003] Gravity retaining wall is widely used in geotechnical engineering. It relies on its own gravity to resist the soil pressure on the back of the wall. The wall is generally made of plain concrete poured on site, but it has a large structural size, long cast-in-place and maintenance time, The construction quality is not easy to guarantee and other shortcomings. With the development of railways in plateau mountainous areas, the construction environment is high in altitude, lack of oxygen, and a serious shortage of manpower. Therefore, there is an urgent need for a gravity-type retaining wall structure with a high level of construction mechanization and less manpower demand to meet the needs of railway subgrades in plateau mountainous are...
