Occlusion retaining wall pile and its construction method and application

Abstract

The invention discloses an engaged retaining pile. The engaged retaining pile comprises a plurality of plain concrete piles laid from front to back and a plurality of reinforced concrete piles laid from front to back. The plain concrete piles and the reinforced concrete piles are laid in a staggered mode. A pile body of each reinforced concrete pile is engaged with pile bodies of two plain concrete piles located front and back, so that the retaining effect is good. The invention further discloses a construction method of the engaged retaining pile. The construction method comprises the steps that firstly, construction of the plain concrete piles is conducted, and the multiple plain concrete piles are constructed from front to back; and secondly, construction of the reinforced concrete piles is conducted, the multiple reinforced concrete piles are constructed from front to back in the construction process of the multiple plain concrete piles, drilled hole-forming construction processes of any one of the reinforced concrete piles are conducted after the construction of the two adjacent plain concrete piles front and back is completed. The construction method is simple; the design is reasonable and the construction is simple and convenient; the construction efficiency is high and the construction effect is good. In addition, the invention discloses an application of the engaged retaining piles, namely a foundation pit retaining structure is formed by fixedly connecting the multiple engaged retaining piles tightly.

Description

technical field [0001] The invention belongs to the technical field of foundation construction, and in particular relates to an occlusal retaining wall pile and its construction method and application. Background technique [0002] After the excavation of the foundation pit, the earthwork of the slope will collapse into the pit due to the lateral pressure, so the foundation pit protection wall is required. There are many ways to protect the wall of the foundation pit, such as bolting, soil nailing, shotcrete, and retaining piles. Among them, the wall retaining piles are further divided into occlusal piles and non-occlusal piles according to the form of pile arrangement, and the occlusal piles form the retaining pile walls for the wall protection of the foundation pit. The occlusal cast-in-place pile is a way of retaining the wall of the foundation pit. But nowadays, there is no uniform, standardized and specific construction method to follow when using occlusal piles to pr...

AI Technical Summary

Problems solved by technology

But nowadays, there is no uniform, standardized and specific construction method to follow when using occlusal piles to protect the wall of the foundation pit. When using the above-mentioned traditional construction methods, the construction operations are inevitably random, irregular and cumbersome. , slow construction speed, low construction work, the construction quality of occlusal cast-in-situ piles cannot be effectively guaranteed, and the use effect is poor, and many other problems, and the scope of application is limited. It is difficult or impossible to drill when encountering dense sand and pebble formations or large diameter pebble formations, so the adaptability of the soil layer is insufficient, and it cannot be used in some areas.
