Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a device and method for cleaning the core soil of precast hollow pipe piles. Background Technology

[0002] In construction engineering, precast hollow pipe piles often require concrete core grouting. The grouting depth is generally 2m to 5m. After the precast hollow pipe pile is driven into the ground, the core will be filled with soil, so it needs to be cleared to the designed depth before core grouting can proceed.

[0003] Conventional methods for cleaning the core soil of piles involve manual or mechanical auger excavators. Manual excavation is inefficient and slow. Mechanical auger excavators are noisy, pose certain safety hazards, and leave soil residue on the pile sidewalls, making them difficult to clean completely. Additionally, the soil at the pipe opening needs to be cleaned up promptly.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0034] Continue reading Fig. 2 and Fig. 3 As shown, the water spray pipe 2 includes: pipe body 21 and pipe cap 22.

[0035] The pipe body is vertically installed within the cavity of the precast hollow pipe pile. The pipe body 21 has an upper port and a lower port. The upper port of the pipe body 21 is connected to the pumping pipe 23.

[0036] The pipe cap 22 has an open end and a closed end. The diameter of the pipe cap 22 gradually decreases from the open end to the closed end 3. The open end is connected to the lower port. The pipe wall of the pipe cap 22 is provided with a jet hole 220.

[0037] In this embodiment, the pipe cap 22 is conical. The pipe cap is used to break the pile core soil of the lower layer.

[0038] As a preferred embodiment, the number of jet holes 220 is multiple 3. The multiple jet holes 220 are arranged along the circumferential direction of the pipe cap 22.

[0039] In this embodiment, the water suction pipeline 23 is provided with a booster pump 24. The booster pump 24 is arranged in the clean water tank 13.

[0040] The sewage pump 3 is connected to the sewage tank 11 through the slurry discharge pipeline 31. The sewage pump 3 is arranged in the inner cavity to discharge the mud water slurry. The sewage pump 3 is connected with a sling 32. The sling 32 is connected with a winding device. The winding device is installed at the pile mouth of the prefabricated hollow pipe pile 4.

[0041] The prefabricated hollow pipe pile core soil cleaning device of the application uses a water jet to flush the pile core soil from top to bottom in the inner cavity of the prefabricated hollow pipe pile, cooperates with the sewage pump to discharge the mud water slurry formed by the dispersed pile core soil through the water jet, uses the disposal tank to precipitate the mud water slurry and collect the supernatant for recycling clean water to form a water jet to flush the pile core soil, which not only ensures the cleaning speed, but also almost has no noise during cleaning, and the cleaned soil can be discharged to the designated position in time. The prefabricated hollow pipe pile core soil cleaning device of the application also has the effect of cleaning the pile wall, which ensures the connection quality between the post-core concrete and the pile wall.

[0042] The prefabricated hollow pipe pile core soil cleaning device of the application is especially suitable for use in a southern silt foundation pit.

[0043] The application provides a prefabricated hollow pipe pile core soil cleaning method, which comprises the following steps:

[0044] S1: providing the prefabricated hollow pipe pile core soil cleaning device, wherein the disposal tank 1 is arranged near the prefabricated hollow pipe pile 4 to be cleaned.

[0045] S2: connecting the water jet pipe 2 to the clean water tank 13 of the disposal tank 1 through the water suction pipeline 23.

[0046] S3: aiming the water jet pipe 2 at the pile core soil 41 in the inner cavity of the prefabricated hollow pipe pile 4 and spraying a high-pressure water jet to flush the pile core soil 41 from top to bottom to form a mud water slurry in the inner cavity.

[0047] The booster pump is started to deliver clean water in the clean water tank to the water jet pipe through the water pumping pipeline to generate high pressure water jet through the cap of the water jet pipe. The jet hole is vertically arranged with the pipe wall of the cap, and then is arranged at an angle with the pipe body, that is, is arranged obliquely downward and outward, so that the multiple high pressure water jets are umbrella-shaped water curtain jetted to the pile core soil.

[0048] During the flushing process, the water jet pipe can efficiently and quickly flush the pile core soil to form the mud water slurry by rotating and pulling up and down the pipe body.

[0049] S4: The mud water slurry in the inner cavity of the sewage pump 3 is arranged, and the sewage pump 3 is started to pump the mud water slurry in the inner cavity to the sewage tank 11 of the disposal tank 1 through the slurry pipeline 31.

[0050] During the discharge of the mud water slurry, the lifting cable is reeled in and out by the cable reel device (such as a winch) to change the up and down position of the sewage pump, avoid the sewage pump being blocked, and make the sewage pump continuously discharge the mud water slurry to the sewage tank for disposal tank processing.

[0051] S5: The mud water slurry in the sewage tank 11 flows into the sedimentation tank 12 of the disposal tank 1 through the first overflow hole to form supernatant.

[0052] S6: The supernatant flows into the clean water tank 13 through the second overflow hole for the water jet pipe 2 to jet high pressure water jet.

[0053] When the water jet pipe flushes the pile core soil to the designed depth, the water jet pipe lance can be moved up and down to clean the residual soil on the pile wall. After cleaning, the water jet pipe is pulled out, the residual mud water slurry is pumped out, and then the concrete can be poured.
