Problems solved by technology

[0005] 1. The traditional concrete sheet pile refers to the pile body formed by the reinforced concrete sheet pile prefabricated component pile sinking, so the size, length and economy of the pile are limited by the processing and transportation conditions
[0006] 2. Reinforced concrete sheet piles are usually driven by hammering method, which has large vibration and noise, and is subject to certain restrictions in urban engineering

Embodiment Construction

[0046] The present invention will be described in further detail below with reference to the accompanying drawings and specific preferred embodiments.

[0047] like figure 1 As shown, a valve type concrete sheet pile hole forming device includes a steel formwork 10 and a valve type pile shoe 30 .

[0048] The center of the steel formwork is provided with a pouring cavity 13 with a rectangular section, and the length-width ratio of the rectangular section of the pouring cavity is increased.

[0049] The top of the steel formwork or the top of the side wall is provided with a concrete pouring sprue 11 .

[0050] like figure 2 As shown, several stiffening plates 12 are preferably uniformly distributed on the outer wall of the steel formwork along the circumferential direction, and both the steel formwork and the stiffening plates are preferably high-strength steel plates. Each reinforced slab is preferably arranged vertically, so the overall rigidity of the steel formwork can...

Abstract

The present invention disclosed a living petal concrete pile pile pile formation device and hole -forming method, including steel templates and live petal pile boots; the center of the steel template is set with an cross -section of pouring cavity, the top or side of the steel template, the top or side of the steel templateThere is a concrete pouring entrance at the top of the wall; the live petal pile boots are set at the bottom of the steel template. The live petal pile boots include two triangle plates and two live petal baffles;The live petal baffle is hinged with the bottom of the steel template; the bottom of the two living petals baffle is provided with oblique tip and magnet; when the two diagonal tips are adsorbed, the two live petals and two pieces are two.The triangular board is pasted, and a seal pouring cavity connected to the pouring cavity is formed.The present invention can make the board piles in the construction site formed a hole -in -shaping molding, eliminating complex intermediate links, reducing the cost, and the depth of the entry of board piles can also increase significantly.In addition, it can reduce environmental noise and improve construction efficiency.

Description

technical field [0001] The invention relates to pile foundation engineering, in particular to a hole-forming device and a hole-forming method for a flap-type concrete sheet pile. Background technique [0002] Concrete sheet piles have the advantages of high strength, high rigidity, convenient material acquisition, and simple construction. [0003] Before the development of underground diaphragm wall and bored cast-in-place piles, steel sheet piles and concrete sheet piles were basically used for the enclosure structure in foundation pit engineering. Compared with steel sheet piles, concrete sheet piles do not have to consider the problem of pile extraction. [0004] However, with the development of the times, compared with other types of pile foundations, the limitations of concrete sheet piles have become increasingly prominent, and the following shortcomings need to be improved: [0005] 1. The traditional concrete sheet pile refers to the pile body formed by the reinfor...
