Description

Technical Field

[0001] This utility model belongs to the field of cast-in-place pile construction technology, specifically relating to a pile hole cleaning device. Background Technology

[0002] In the construction of photovoltaic power stations in mountainous and Gobi desert areas, micro-grown piles are often used as the foundation for photovoltaic supports. These piles are generally micro-drilled piles with a diameter of 300mm or less and a depth of no more than 2.5m. The construction equipment mainly uses auger drilling rigs and down-the-hole drilling rigs depending on the lithology of the photovoltaic field. After drilling, there is a thick layer of loose soil at the bottom of the hole. If the loose soil is not poured in time after the pile is formed, the thickness will be further increased due to factors such as hole collapse and rainwater. The thickness of the loose soil exceeds the specifications and design requirements, which has a significant impact on the quality of subsequent micro-grown piles. Summary of the Invention

[0003] In view of this, the purpose of this utility model is to provide a pile hole cleaning device to solve the problem of excessive loose soil at the bottom of micro-drilled cast-in-place pile holes and eliminate the adverse effects of excessive sediment thickness on the quality of micro-drilled cast-in-place piles.

[0004] The present invention discloses a pile hole cleaning device comprising a first connecting pipe, a second connecting pipe, a third connecting pipe, and an air compressor; the outlet end of the first connecting pipe is connected to the inlet end of the second connecting pipe at an angle and interconnected; the outlet end of the third connecting pipe is connected to the pipe body of the first connecting pipe, and the inlet end is connected to the gas output port of the air compressor; the diameter of the third connecting pipe is smaller than the diameter of the first connecting pipe.

[0005] When using the equipment, place the inlet end of the first pipe downwards into the pile hole to be cleaned, and the outlet end of the second pipe upwards. Connect the air compressor's air output port to the third pipe on the first pipe body. Turn on the air compressor to send air to the bottom of the pile hole. Loose soil and sediment at the bottom of the hole are carried by the airflow through the larger diameter first pipe and discharged through the second pipe, thus achieving the purpose of cleaning the pile hole. The first and second pipes are connected at an angle to disperse the dust far away from the pile hole and prevent it from falling back into the pile hole and surrounding area.

[0006] Furthermore, the included angle α between the axes of the first and second pipes is 25°-35°, which ensures that dust is discharged to the side while also preventing the flow rate from decreasing due to an excessively large turning angle at the connection between the first and second pipes, thus affecting the cleaning effect.

[0007] Furthermore, the angle β between the axes of the first conduit and the third conduit is 35°-55° to prevent dust from entering the third conduit.

[0008] Furthermore, the diameter R1 of the first conduit is 80mm-120mm to accommodate the diameter of 150mm-300mm commonly used in the foundation piles of photovoltaic supports.

[0009] Furthermore, the diameter R2 of the third conduit is 20mm-32mm to generate greater air pressure and adapt to the air pipe diameter of most commercially available air compressors.

[0010] Furthermore, the distance L4 between the outlet end of the third pipe and the outlet end of the first pipe is 45-55cm, so as to avoid L4 being too long and affecting the scum discharge effect, and L4 being too short and causing the air intake and dust exhaust airflow to be unable to be effectively separated.

[0011] Furthermore, the third conduit is equipped with a valve for closing the gas passage.

[0012] Furthermore, a handle is provided on the outside of the first conduit body to enhance operability and stability during construction.

[0013] This utility model has the following beneficial effects: 1. The pile hole cleaning device provided by this utility model has a simple and lightweight structure, is easy to process, has low cost, and is convenient to use.

[0014] 2. Compared with the traditional manual excavation and cleaning of loose soil at the bottom of cast-in-place piles, this utility model has high hole cleaning efficiency and can effectively improve the quality of micro-cast-in-place piles. Attached Figure Description

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] like Figure 1 As shown, this utility model discloses a pile hole cleaning device, including a first through pipe 100, a second through pipe 200, and a third through pipe 300. The lower end of the first through pipe 100 is the inlet end, and the upper end is the outlet end; the lower end of the second through pipe 200 is the inlet end, and the upper end is the outlet end.

[0019] A first connecting pipe 100, with a diameter R1 of 100 mm and a length L1 of 300 cm, is connected at its upper end to a second connecting pipe 200, with a diameter of 100 mm and a length L2 of approximately 20 cm. The angle α between the axes of the first connecting pipe 100 and the second connecting pipe 200 is 30°. At a distance L4 50 cm from the outlet end of the first connecting pipe 100, the first port of a third connecting pipe 300 is connected to the first connecting pipe 100. The distance L3 between the inlet end of the third connecting pipe 300 and the inlet end of the first connecting pipe 100 is 250 cm. The second port of the third connecting pipe 300 is connected to the gas outlet of an air compressor 400. The diameter R2 of the third connecting pipe 300 is 20 mm, and the angle β between the axes of the third connecting pipe 300 and the first connecting pipe 100 is 45°.

[0020] In some embodiments, a valve is provided on the third conduit 300.

[0021] In some embodiments, the first conduit 100, the second conduit 200, and the third conduit 300 are all steel pipes, welded together, and a handle is welded to an appropriate position on the body of the first conduit 100 to enhance operability and stability during construction.

[0022] The usage process is as follows: First, the lower end of the first connecting pipe 100 is placed into the already drilled pile. The air compressor 400 air supply pipe is connected to the valve on the third connecting pipe 300. The operator holds the pipe and adjusts the direction of the slag discharge hole at the top of the second connecting pipe 200.

[0023] Then, the interface valve of the air compressor 400 is opened. The air pressure generated by the air compressor 400 will clear the loose soil and sediment at the bottom of the hole through the first pipe 100 and the second pipe 200, and then send it away from the pile hole through the outlet end of the second pipe 200.

[0024] After cleaning the bottom of the hole, close the valve, lift the pipe and check the cleaning effect.

[0025] After cleaning the hole, move the device to the next hole. During the construction process, the pipe fittings can be moved up, down, left, and right to improve the cleaning effect.
