Description

Technical Field

[0001] The utility model relates to the technical field of cast-in-place pile construction, in particular to a hole cleaning device for the foundation of a mountain photovoltaic micro-hole cast-in-place pile. Background Technique

[0002] During the construction of mountain photovoltaic micro-hole cast-in-place piles, a large amount of soil chips and rock chips will be generated and deposited in the holes. If the drill cuttings in the holes are not removed in time and effectively, it will cause the hole depth and bearing capacity not to meet the design requirements. At present, the main hole cleaning methods for mountain photovoltaic micro-hole cast-in-place piles are: manual slag removal method, bailer hole cleaning, hole cleaning bit hole cleaning, down-the-hole drill: after the hole is formed, the sediment in the hole is blown out through the reverse circulation of the air compressor, which is mostly used for the construction of micro-hole cast-in-place piles with small slopes that can be mechanically drilled;

[0003] However, in the prior art, the manual slag removal method is time-consuming and laborious, and it is easy to damage the hole wall when operating the fixture, resulting in collapse. The traditional air compressor slag blowing method has poor effect on large soil blocks. At the same time, using the air compressor to generate negative pressure to suck slag may also cause the collapse of the soil wall at the bottom of the micro-hole cast-in-place pile;

[0004] In the prior art, the invention patent CN111411908B discloses a comprehensive hole cleaning device for bored cast-in-place piles and its hole cleaning method. Through the cooperation of a conduit, an air supply device, a gas-liquid dual pipeline, a mixer, a flusher, a mud treatment device, and a mud pump, the compressed air generated by the air compressor enters the air channel and is ejected from the air nozzle of the mixer, mixing with the mud and drill cuttings in the conduit to form a three-phase mixed flow of mud, drill cuttings, and air. The three-phase mixed flow rises along the conduit and then is ejected. This is also a commonly used technical solution in the prior art, but this solution has a complex structure, high cost, large installation difficulty, and is extremely inconvenient for disassembly and movement, seriously affecting the construction efficiency.

One end of the telescopic rod 5 away from the slag suction pipe 4 is fixedly connected to an arc-shaped baffle 10 through a telescopic inner pipe. A motor 6 is arranged at a position parallel to the telescopic rod 5 on the outer surface of the bottom of the slag suction pipe 4. A rotating shaft 7 is fixedly connected to the bottom of the motor 6. A crushing disc 8 is fixedly connected to the bottom of the rotating shaft 7. In this embodiment, the soil particles in the micropile are discharged through the slag discharge pipe 3 and the slag suction pipe 4 of the air compressor. During use, the telescopic rod 5 is adjusted according to the diameter of the pile to adjust the width of the arc-shaped baffle 10, and then the slag suction pipe 4 is inserted into the micropile. The motor 6 is started, and the motor drives the rotating shaft 7 to rotate, driving the crushing disc 8 to rotate to crush and stir the large-volume soil at the bottom of the hole of the micropile. Finally, the air compressor is turned on to blow out the soil.

[0021] Preferably, a connecting pipe 11 is arranged at the air outlet of the air supply pipe 2. Both ends of the connecting pipe 11 are detachably connected to the air supply pipe 2 and the slag discharge pipe 3 respectively. A control valve 9 is arranged on the connecting pipe 11. In this embodiment: The connecting pipe 11 is threadedly connected to the air supply pipe 2 and the slag discharge pipe 3, and the detachable connection is realized through threaded cooperation, which is more convenient for assembly or disassembly. By setting the control valve 9, the main purpose is to control the air flow size of the air supply pipe 2.

In this embodiment, during use, the slag suction pipe 4 of the L-shaped cylinder is fixedly connected to the slag discharge pipe 3 by welding, and other fixed connection methods can also be adopted.
