Problems solved by technology

However, in terms of the mechanical characteristics of the structure itself, the main disadvantage of the single-stage cantilever (buttress) retaining wall is that the excessively high cantilever will cause the structure to bear large bending moments and shear forces
Corresponding to the angle of high and steep slope support, narrow construction site and engineering greening, the engineering application of single-stage cantilever retaining wall is greatly restricted

Embodiment 1

[0090] As shown in Figure 3, the single-stage cantilever retaining wall can be cast in situ or prefabricated assembled structure, and the two-stage cantilevered L-shaped retaining wall should adopt prefabricated assembled structure. When the assembled construction is adopted, firstly, the upper and lower L-shaped retaining walls are prefabricated according to the design height of the wall. The width of each unit wall can be divided into 1.0~2.0m according to the transportation capacity of the vehicle, and then transported to the construction site to complete the assembly of the retaining wall structure. Use in areas with 8 degrees.

[0091] As shown in Figure 9, the construction process mainly includes wall prefabrication, foundation trench excavation, foundation treatment, waterproof and drainage facilities, transportation and assembly of prefabricated parts, filling and compaction, landscape restoration, etc. The construction process is shown in Figure 9. 9. The difference...

Abstract

The invention discloses a two-level battlements type cantilevered L-shaped barricade and a construction method thereof. The composite barricade is composed of an upper layer single level cantilevered L-shaped barricade and a lower layer single level cantilevered L-shaped barricade both of which are blocked up down. An unloading platform is formed by using the bottom plate of the upper level single level cantilevered L-shaped barricade. The invention also discloses an administration method for the two-level battlements type cantilevered L-shaped barricade. According to the invention, single level cantilevered L-shaped barricade has a single structure, a small weight, little land occupied, and low requirement for foundation stress, and is adaptive to alternation distortion and ecological protection. Both the anti-overturn ability and skid resistance character of the single level cantilevered L-shaped barricade are utilized. Barricade height is increased in precondition the self weight of the barricade after soil is filled is utilized.

Description

technical field [0001] The invention relates to the technical field of subgrade engineering, in particular to a two-stage stacked cantilever type L-shaped retaining wall and an implementation method thereof. Background technique [0002] There are many types of retaining walls used in projects, which are usually classified according to structural type, building materials, wall back shape, position of the wall on the section, construction method and environmental conditions. According to the structural type, the retaining wall can be divided into a gravity type (including counterweight type) and a light type retaining wall. [0003] Gravity retaining walls have been used more in subgrade retaining projects in my country. In recent decades, many lightweight retaining walls made of reinforced concrete components have been developed, such as reinforced concrete cantilever retaining walls, reinforced soil Retaining wall, anchor plate retaining wall, anchor (cable) retaining wall,...
