Equipment for removing sediment inside small-diameter pipe piles and its application method

Abstract

The invention relates to the technical field of sediment discharge equipment, and provides equipment for removing sediments in a small-diameter pipe pile and an application method of the equipment. The equipment comprises a hydraulic power device, a traction sinking device, a vertical push device and a residue storage device. The hydraulic power device comprises a vertical drive hydraulic cylinder. The outer portion of the vertical drive hydraulic cylinder is provided with a horizontal supporting hydraulic cylinder. At least two fixing supporting feed are arranged in the horizontal supporting hydraulic cylinder. The traction sinking device comprises a traction rope. The traction rope is connected with the vertical drive hydraulic cylinder. The vertical push device comprises a connection cylinder. The connection cylinder is arranged at the bottom of the vertical drive hydraulic cylinder and communicated with the vertical drive hydraulic cylinder. A vertical thrust shaft is arranged in the connection cylinder and can move in the connection cylinder in the vertical direction. The residue storage device comprises a residue storage cylinder. The residue storage cylinder is movably connected with the vertical thrust shaft. A bottom sealing plate is hinged to the bottom of the residue storage cylinder. A residue storage portion rope is connected with the bottom sealing plate. The equipment is easy to operate, convenient to assemble and capable of removing rock blocks and brick residues in the pipe pile.

Description

technical field [0001] The invention relates to the technical field of slag discharging equipment, in particular to a device for removing slag inside a small-diameter pipe pile and a method for using the same. Background technique [0002] Pipe piles refer to high-strength prestressed concrete pipe piles or steel pipe piles, etc. Pipe piles are commonly used as a ground treatment method for soft soil foundations. The piles are driven piles. For the saturated muddy and cohesive soil layers with high water content, there are often problems such as radial cracks in the pile body and welding at the pile connection position due to the lax control of the pile driving process and the soil squeezing effect caused by pile driving. Therefore, it is necessary to deal with the defects of pipe piles. At present, the commonly used method is to place a reinforcement cage above the internal defect position of the pipe pile, and then pour micro-expansion concrete for reinforcement and reinf...

AI Technical Summary

Problems solved by technology

At present, the commonly used method is to place a reinforcement cage above the internal defect position of the pipe pile, and then pour micro-expansion concrete for reinforcement and reinforcement. Before this, the sediment in the pipe needs to be removed. How to remove the residue is the key issue in the treatment of pipe pile defects. One, the diameter of commonly used pipe piles is generally 600mm to 1000mm, and the diameter of the pipe is small. In addition, the location of the defect is generally located deep in the pipe pile. It is difficult for the construction personnel to go down to the working face to clean the slag in the pipe. As the middle depth increases, the air in the pipe becomes thinner gradually, which poses a great construction safety hazard. Therefore, the high-pressure mud pump is generally used to directly pump the mud-water mixture in the pipe, and the construction efficiency is low. In addition, the residual brick slag, block stones and other sundries in the pipe, It cannot be extracted through the mud discharge pipe. With the gradual increase of the depth of the hole cleaning, the construction efficiency of the hole cleaning will be seriously restricted. If the brick slag and block stones within the quality defect range cannot be removed, the reinforcement and reinforcement treatment effect of the pipe pile will be affected.

In addition, mud pump slag needs to control the mud content of the mud, often need to fill the pipe with water, the mud volume is large, it is necessary to set up a sedimentation tank to settle the mud water, and the discharge of residual water has a great impact on the surrounding environment of the project. In many For projects close to the center of the city, the above hole cleaning scheme is difficult to operate
