Description

Technical Field

[0001] The utility model relates to the technical field of pipe pile hole cleaning, in particular to a hole cleaning device suitable for prestressed pipe piles. Background Art

[0002] At present, the commonly used equipment for pile core excavation is the pipe pile core excavator. The traditional method is to weld a spiral blade device (Luoyang shovel) at the bottom of the steel pipe and use manual rotation to extract it. This method is inefficient, with high labor and time costs. The steel pipe is too long for the operator to operate, and it is also very easy to cause injuries.

[0003] However, the use of pipe pile excavator equipment, which is more mature in the market, has exposed mechanical drill screws, which may cause injuries when encountering hard objects thrown out of the soil, and the risk factor is relatively high. In addition, the pipe pile excavator has high requirements on the cooperation of the operators, and the power generated during operation cannot be accurately controlled, which makes it easy to over-excavate and damage the pipe wall. The purchase and maintenance costs of the machinery are high, and the replacement of drill bits requires high professional skills. Therefore, we provide a hole cleaning device suitable for prestressed pipe piles. Utility Model Content

To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a hole cleaning device suitable for prestressed pipe piles, comprising a fixed pipe pile, a circulation assembly is provided on the top of the fixed pipe pile, the circulation assembly comprises a fixed frame, the fixed frame is fixedly connected to the top of the fixed pipe pile, the inner wall of the fixed frame is fixedly connected to a high-pressure water pump, the bottom of the high-pressure water pump is fixedly connected to a high-pressure water pipe, the interior of the fixed pipe pile is movably connected to a sewage pipe, one end of the sewage pipe is fixedly connected to the sewage pump, a slurry discharge groove is provided on one side of the sewage pump, and the inner wall of the slurry discharge groove is movably connected to the sewage pipe. By installing the circulation assembly, the high-pressure water pump is used to flush the silt at the bottom of the fixed pipe pile, and the silt, sediment and debris in the fixed pipe pile are mixed with water. The mixed debris enters the interior through the filter hole of the outer pipe for secondary filtration. The water after secondary filtration enters the primary sedimentation tank and the final sedimentation tank through the sewage pipe, and enters the high-pressure water pump again through the high-pressure pipe for use, which not only realizes the utilization of water circulation, but also greatly reduces the construction cost and minimizes the pollution to the surrounding environment.

[0013] In the present utility model, the double screen meshes of the inner pipe and the outer pipe cooperate to effectively filter the sundries inside the fixed pipe pile. The sundries are stored in the outer pipe. When there is more sediment, it can be lifted out of the fixed pipe pile for cleaning operations, effectively improving the cleaning effect of the fixed pipe pile, enhancing the practicability of the device, ensuring the bonding force between the core filling concrete and the inner wall of the fixed pipe pile, and meeting the bearing capacity requirements of the fixed pipe pile.
