Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a device for cleaning the wall of interlocking piles. Background Technology

[0002] Interlocking piles are a common foundation treatment technique. During the interlocking process, the pile walls at the interlocking area need to be cleaned to ensure the quality and stability of the pile. Currently, the main technologies used in the market include hydraulic washing and pneumatic cleaning, but both have some drawbacks. Hydraulic washing requires using a high-pressure water gun to repeatedly rinse the pile body to remove silt and debris from the pile surface. However, this method can easily lead to soil erosion around the pile, affecting its stability. Simultaneously, the high-pressure water can also damage the pile body, thus affecting its quality. Pneumatic cleaning uses a pneumatic drilling rig to compress air into the pile hole, blowing out the soil inside the pile to achieve a cleaning effect. However, pneumatic cleaning has a limited range of action, only cleaning the surface of the pile hole and failing to achieve deep cleaning. Furthermore, pneumatic drilling rigs require a large air supply, resulting in higher construction costs.

[0003] Therefore, how to create a new device for cleaning the wall of interlocking piles is one of the important research and development topics at present. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a device for cleaning the wall of interlocking piles, which can conveniently and efficiently clean the mud on the wall of interlocking piles, improve the interlocking effect and construction quality of interlocking piles, reduce the slag inclusion rate, enhance the water-stopping ability of interlocking piles, improve construction efficiency and reduce costs, thereby overcoming the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, this utility model provides a pile wall cleaning device for interlocking piles, including a connecting pin, an arc-shaped steel plate and a steel brush. The steel brush is fixedly connected to the outer surface of the arc-shaped steel plate. The two arc-shaped steel plates are arranged opposite each other and have holes at the same height on the center line. The connecting pin passes horizontally between the two arc-shaped steel plates. The end of the connecting pin is machined with an external thread for locking the two arc-shaped steel plates to the two ends of the connecting pin with nuts.

[0006] As an improvement of this utility model, the outer wall of the rotary drilling machine's drill barrel is perforated, and a connecting pin passes horizontally through the drill barrel and fixes two arc-shaped steel plates on the outside of the drill barrel. The vertical shaft of the rotary drilling machine extends and retracts, driving the two arc-shaped steel plates and steel brushes to move up and down in the hole of the rough pile, which is used to clean the mud on the pile wall at the joint of the rough pile and the plain pile.

[0007] Furthermore, the thickness of the arc-shaped steel plate is 1-5mm.

[0008] With this design, the present invention has at least the following advantages:

[0009] 1. This utility model can effectively clean the residual mud on the pile wall of the interlocking part, reduce the slag inclusion rate, improve the strength and water-stopping performance of the interlocking pile, improve the construction quality and service life of the interlocking pile, and reduce the cost of later maintenance.

[0010] 2. The arc-shaped steel plate and the connecting pin are detachably connected, which is not only easy to install and reusable, but also allows for the production of arc-shaped steel plates of different specifications to suit different hole diameters;

[0011] 3. Compared with pneumatic cleaning, it has a more comprehensive cleaning range and can completely cover the interlocking parts. Compared with water pressure cleaning, it is more efficient and can clean without repeated operation.

[0012] 4. Easy to operate, requires no professional skills from construction personnel, and is easy to promote and popularize;

[0013] 5. It has a simple structure, is easy to manufacture, and has low cost. Attached Figure Description
