Hydraulic sheeting and use method thereof

Abstract

A hydraulic plug-in board includes reinforcement concrete pile board and water pipes installed in it vertically, water distribution pipes which bottom is installed horizontally and connected with water distribution pipes, preformed reinforcement which is buried and one side is equipped with slideway, another side is equipped with slide board and the top is equipped with hoisting lifting ring, vertical baffle water way which is installed on said concrete pile board, two sides of slideway and slide board. Its usage includes:(A) lifting the reinforcement concrete pile board with hoisting equipment, putting it into ground layer by the mode of hydraulic injection through the water pipes and the water distribution pipes, inserting the slide board of another reinforcement concrete pile board into ground layer through the hollow square steel slideway with gap in ground layer; (B) overall connectivity between the boards, firstly cleaning-up the baffle water way with flush pipe, then putting rectangular casting bag into it and filling with cement mortar to forming a inner chamber water between boards and isolated with outer of board; (C) putting the slip casting pipe into the hollow square steel in said inner chamber, filling it with cement mortar from bottom to up, to making the whole combining part between boards form a concrete pile board whole device with sandwich steel board; (D) casting-in-situs or not the top beams.

Description

1. Technical field [0001] The invention relates to water conservancy projects such as embankment projects, port waterway projects, artificial islands in water, road traffic bridges, sluices, culverts, water delivery channels, etc., and reinforced concrete underground integral projects, in particular to a hydraulic insert and its use method. 2. Background technology [0002] At present, the common shortcomings and deficiencies of various reinforced concrete pile-slab construction projects that use hydraulic sprinting to enter the ground are: ①The pile entry method completely relies on a single hydraulic sprint, on the one hand, the pile entry is slow, and on the other hand, it encounters underground obstacles It is difficult to pass and exclude objects; ② It is difficult to form an integral structure with high strength and high degree of sealing at the pile-slab joint. Although the Chinese patent ZL200420040430.8 "Hydraulic Insert Slideway Skateboard" proposes a pile-slab con...

Problems solved by technology

[0002] At present, the common shortcomings and deficiencies of various reinforced concrete pile slab construction projects that use hydraulic sprinting to enter the ground are: ①The pile entry method completely relies on a single hydraulic sprint, on the one hand, the pile entry is slow, and on the other hand, it encounters underground obstacles It is difficult for objects to pass through and be excluded; ②It is difficult to form an integral structure with high strength and high degree of sealing at the pile-slab joint

Although the Chinese patent ZL200420040430.8 "Hydraulic Insert Slideway Skateboard" proposes a pile-slab connection technology, there is no water barrier at the junction of the two boards and a sealed inner chamber cannot be formed, resulting in the cement slurry injected into the bottom of the junction of the two boards. Because of the leakage problem, it is difficult to achieve the predetermined sealing effect if it cannot be returned to the top of the pile slab normally; ③ Each pile slab needs to be equipped with water pipes, jet water pipes or hydraulic power Sprinklers, resulting in a substantial increase in processing costs and steel consumption

During the construction process, each pile slab must be connected to a high-pressure water supply pipeline, which prolongs the construction time and increases the construction cost
