Embodiment Construction

[0027] Below in conjunction with accompanying drawing, construction method of the present invention is described in detail.

[0028] Such as figure 2 As shown, the construction process of the present invention can be briefly summarized as follows: A1 pile forming hole → burying A1 pile occlusal pipe → pouring A1 pile concrete → A2 pile forming hole → burying A2 pile occlusal pipe → pouring A2 pile concrete → pulling out A1 pile occlusal Pipe→A3 pile forming hole→burying A3 occlusal pipe→pouring A3 pile concrete→pull A2 pile occlusal pipe→B1 pile forming hole→installing B1 pile reinforcement cage→pouring B1 pile concrete→A4 pile forming hole→burying A4 occlusal pipe→pouring Concrete for pile A4 → pull out the occlusal pipe of pile A3 → form a hole for pile B2 → install the reinforcement cage for pile B2 → pour concrete for pile B2... and proceed in this cycle.

[0029] Refer to the specific construction process figure 2 flow chart and image 3 The schematic diagram of hois...

Abstract

The invention relates to a biting pile construction method and a biting pipe applied to the method. The biting pile construction method is completed mainly by repeatedly mounting and demounting the biting pipe on the intersection portion of a plain concrete pile and a reinforced concrete pile. The biting pipe is formed by one or more biting pipe bodies. Each biting pipe body is of an integrally-formed structure formed by welding two arc steel plates. The pipe opening shape of each biting pipe body is the same as the shape of the intersection portion of the plain concrete pile and the reinforced concrete pile. According to the brand-new biting pile construction method, the multiple defects brought by cutting of concrete on intersection parts of an A1 pile, an A2 pile and an A3 pile in the prior art are overcome.

Description

technical field [0001] The invention relates to the technical field of foundation pit support, in particular to a construction method of an occlusal pile and an occlusal pipe applied to the method. Background technique [0002] At present, with the rapid development of cities, more and more underground spaces are being used, and there are more and more forms of foundation pit support. Among the many forms of foundation pit support, occlusal pile support is widely used in construction because it not only has the maintenance and anti-seepage function of the underground diaphragm wall, but also has the advantages of reducing the reinforcement ratio of steel bars and reducing the cost of the project. Specifically, the occlusal pile is a foundation pit support structure that forms a mutual occlusal queue between the piles. The arrangement of the piles is an unreinforced ultra-retarded concrete pile (A pile) and a reinforced concrete The piles (B piles) are arranged at intervals....
