Embodiment 1

[0173] A concrete prefabricated retaining wall of manual digging piles, the prefabricated retaining wall comprises: a retaining wall main body 1 and an elastic structure layer 2 . The retaining wall main body 1 is connected end to end to form a complete concrete retaining wall. The elastic structure layer 2 is arranged on the outer side of the wall main body 1 .

Embodiment 2

[0175] Example 1 is repeated, except that the elastic structural layer 2 includes: a capsule block 201 , and a medium inlet and outlet 202 . The inside of the capsule block 201 communicates with the outside through the medium inlet and outlet 202 . The capsule block 201 is disposed on the outside of the wall main body 1 .

Embodiment 3

[0177] Embodiment 2 is repeated, except that the elastic structural layer 2 further includes: a balancing duct 203 . The capsule blocks 201 between adjacent retaining walls are communicated through a balancing pipe 203 . The prefabricated retaining wall also includes: a water-stop pad 101 . The water-stop pad 101 is arranged on the upper end surface of the main wall main body 1 , and / or the water-stop pad 101 is arranged on the lower end surface of the main wall main body 1 .

Abstract

The invention discloses a manual hole digging pile concrete precast retaining wall and a construction method thereof. The manual hole digging pile concrete precast retaining wall comprises retaining wall bodies and elastic structural layers; and the retaining wall bodies are connected end to end to form the complete concrete retaining wall, and the elastic structural layers are arranged on the outer sides of the retaining wall bodies. According to the manual hole digging pile concrete precast retaining wall, by arranging the elastic structural layers on the outer sides of the retaining wall bodies, the effects of compacting soil, preventing soil collapse and delaying the collapse time are realized, and the personal safety of constructors is better guaranteed.

Description

technical field [0001] The invention relates to a concrete prefabricated retaining wall of an artificial digging pile, in particular to a concrete prefabricated retaining wall of an artificial digging pile, which belongs to the construction field. Background technique [0002] As a traditional pile foundation treatment method, artificial excavated piles have many advantages such as no disturbance to residents, low cost, simple equipment, clear soil layers, clean sediment, and the ability to directly judge the geological conditions of the bearing strata. However, there are restrictive conditions such as high labor intensity, high soil quality and safety protection requirements. The retaining wall of the pile hole is a key component to ensure the safe hole formation of the manual digging pile. At present, cast-in-place concrete retaining walls are commonly used, but due to the limited construction site, the quality of the concrete is not easy to guarantee and the construction...
