[0002] As an important part of foundation and foundation engineering, pile foundation is an engineering measure to bear and transfer building loads on soft soil foundation. It mainly consists of three parts: pile body, pile neck and pile bottom. The pile body transfers the load from the ground to the more solid soil or rock layer.

[0003] During pile foundation construction, unreacted cement slurry will remain at the bottom of the pit to form sediment. Therefore, a sediment cleaning device is needed to deal with the sediment in the pile foundation. During use, the existing sediment cleaning device usually extracts the mud and sediment at the same time, and cannot separate the mud and sediment, resulting in mud waste. In the past, pile foundation sediment and mud were easy to flow back into the pile foundation hole due to untimely sedimentation, which reduced the hole cleaning efficiency, increased the hole cleaning time, and easily caused the risk of hole collapse or hole expansion, affecting the quality of pile foundation hole formation.

[0004] Therefore, it is necessary to provide a new mud box device for effectively separating pile foundation sediment to solve the above technical problems. Utility Model Content

[0025] Working principle: When the device is in use, the air is compressed by the air compressor body 4, and the compressed air enters the pile hole body 1 through the air duct 3 and the conduit 2. The high-pressure gas is mixed with the mud to form a slurry-gas mixture with a density lower than that of the mud in the conduit 2. The slurry-gas mixture rises due to its small specific gravity, forming a negative pressure in the conduit 2. The mud below rises under the negative pressure, and is continuously replenished under the combined action of the air pressure momentum. After the mud and gas form an air-slurry mixture, they continue to rise, thus forming a flow. Because the cross-sectional area inside the conduit 2 is smaller than the annular cross-sectional area between the outer wall of the conduit 2 and the pile wall, a flow velocity and flow rate reverse flow is formed. Circulation, the conduit 2 carries the sediment back out, the conduit 2 pours the sediment into the discharge port 6, the sediment falls onto the filter screen 8, the sediment is filtered and separated from the mud sediment through the filter screen 8, the mud enters the mud box body 7 through the filter screen 8, the sediment falls into the sediment box 10, thereby separating the sediment from the mud, the starting motor 15 drives the first pulley 16 and the second pulley 17 to rotate, the driving rod 18 drives the fixed sleeve 19 to rotate, and the multiple groups of protrusions 20 rotate, so that the protrusions 20 knock and dredge the filter screen 8 to avoid the problem of clogging of the filter screen 8.
