Hydraulic Sliding Insertion Panel and Its Using Method

Abstract

A hydraulic sliding insertion panel comprises a reinforced concrete poling board (1), a flow guide tube (2) is set in the poling board (1) and a water distributing pipe (3) communicated with the flow guide tube (2) is set in the bottom of the poling board; moreover, a slideway (5) and a slide plate (6) are set on the two sides of the poling board (1) respectively, and an erection loop (8) is set on the top of the poling board. The using method comprises steps as follows: (A) firstly, hoisting the reinforced concrete poling board by a lifting appliance and sinking it into the stratum by hydraulic jet via the flow guide tube and the distributing pipe, then inserting the slide plate of the other reinforced concrete poling board into the stratum in the hollow square steel slideway with a gap of the poling board sunk in the stratum; (B) flushing the isolated watercourse firstly, then setting down the strip bag and infusing the grout, so forming an inner cavity isolated from the exterior between the boards; (C) putting a grout pipe into the hollow square steel in the inner cavity, and filling the grout subsequently; (D) casting the top crossbeam in position after seizing the preset steel bars and the added cross steel bars. In addition, step (D) can be omitted according to the requirements of the engineering.

Description

FIELD OF THE INVENTION[0001]The present invention relates to water engineering and reinforced concrete poling board integrated underground engineering, such as embankment, harbor waterway, artificial island, roadway bridge, sluice, culvert and water channel, and particularly to a hydraulic sliding insertion panel and its using method.DESCRIPTION OF THE RELATED ART[0002]The conventional hydraulic insertion of reinforced concrete poling board generally has the following shortcomings: 1. Hydraulic thrusting is the only means, so that sinking is slow and hard to bypass and eliminate the underground obstacles; 2. it is hard to form an integrated structure in the connection portion that has high strength and tightness. Although Chinese patent ZL200420040430.8 SLIDEWAY AND SLIDE PLATE OF A HYDRAULIC SLIDING INSERTION PANEL provides a connection technique, no inner cavity is formed in the connection portion of two panels that cannot be sealed by the water isolation path. Thus grout injected...

Benefits of technology

[0003]The object of the invention is to provide a hydraulic sliding insertion panel that can be quickly sunk into the stratum and effectively remove underground obstacles and the method of using the same. The prior art disadvantages and shortcomings may be effectively overcome by employing the connecting technique in which a connection between two boards which has a strength and tightness fully meeting the performance index of the board body and employing the constructing technique in which the engineering boards with no flow guide tube and water jetting pipe can in combination with a tool board sink into the stratum. In this way, the board sinking speed is increased, the capability of eliminating the underground obstacles is enhanced, the amount of steel consumed is reduced, time spent for loading and unloading of water supply pipe for each board is shortened, and the high strength integral connection between boards is achieved, so as to achieve the object of speeding up construction, reducing the engineering cost, enhancing safety and stability, and altering the constructing pattern of existing engineering construction.

Problems solved by technology

The conventional hydraulic insertion of reinforced concrete poling board generally has the following shortcomings: 1. Hydraulic thrusting is the only means, so that sinking is slow and hard to bypass and eliminate the underground obstacles; 2. it is hard to form an integrated structure in the connection portion that has high strength and tightness.

Thus grout injected into the bottom of the connection portion of two panels cannot normally return to the top of the board due to leakage, thus the expected tightness of the connection portion cannot be achieved.

Each pile board and existing hydraulic sliding insertion panel has to be provided thereon with a flow guide tube, a sprinkler pipe and a sprinkler head, which substantially increases the cost in fabrication and steel consumption.

And the high pressure water supply pipe needs to be connected once for each poling board during construction, thus extending the period spent for construction and increasing cost.
