Problems solved by technology

It occupies a large area when grading, and it cannot be used when conditions do not permit grading. However, when the retaining wall is restricted by the terrain and cross slope, it is often impossible to implement. Therefore, it is sometimes necessary to use a special-shaped support structure for processing. Structural design and on-site pouring construction are relatively complicated, and quality control and large-scale application are not used

Abstract

The invention provides a construction method of a fabricated inverted-V-shaped overhanging retaining wall. The fabricated inverted-V-shaped overhanging retaining wall further comprises an overhangingretaining wall supporting unit, wherein the overhanging retaining wall supporting unit comprises an inverted-V-shaped supporting structure and a prefabricated plate, and the inverted-V-shaped supporting structure comprises outer side supporting feet, inner side supporting cantilever beams and a longitudinal fixing beam. By the adoption of the scheme, in the roadbed pouring process, earthwork can be reduced, the retaining wall can conform to existing industrialized production and field assembly, the quality can be guaranteed, a roadbed supporting structure with certain bearing capacity is provided, an overhanging section is formed on the overhanging retaining wall supporting unit, and the functional requirement for arranging a non-motorized vehicle lane or a sidewalk is met.

Description

technical field [0001] The invention relates to the field of engineering construction, in particular to a construction method for an assembled type in-shaped cantilevered retaining wall. Background technique [0002] The retaining wall is the most commonly used structure in the field of engineering construction when it is necessary to support the filled part. After years of development, retaining walls have developed from the initial gravity type to cantilever, anchored and even trough-shaped retaining walls, and these retaining walls have a wide range of applications. When it is necessary to widen the road surface or set up non-motor vehicle lanes or sidewalks with a small load in highway engineering or other projects, it can only be dealt with by grading, setting retaining walls or other types of support structures. It occupies a large area when grading, and it cannot be used when conditions do not permit grading. However, when the retaining wall is restricted by the terr...
