Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an on-site soil cleaning device in a pile hole for construction engineering. Background Art

[0002] On-site pile holes for construction projects are holes for cast-in-place concrete piles drilled to reinforce the foundation and improve the foundation's load-bearing and earthquake-resistant capabilities. The pile holes are drilled by pile hole drilling rigs, which are special mechanical equipment widely used in water well and pile hole construction. Fully hydraulic pile hole drilling rigs are widely used as the main construction equipment in the construction of water wells in water-scarce areas, the drilling of air-conditioning wells in ground-source heat pump technology, and the construction of pile holes for high-rise building foundations and bridge foundations in urban construction. After the hole is opened, there is still a lot of soil in the pile hole, which needs to be cleaned before pouring concrete.

[0003] The existing device for cleaning soil in pile holes uses a rope to sink a suction pump into the drilled hole, and the suction pump draws out the soil in the pile hole. When the suction pump is sunk, the suction pump collides with the inner wall of the pile hole. When the suction pump sinks to the bottom of the pile hole, the suction pump is close to the inner wall of the pile hole, and the suction force acts on the hole wall, which will cause the hole wall to collapse. At the same time, the soil in the water will settle and settle at the bottom of the pile hole. When the suction pump is extracting, the settled soil will become compacted, resulting in incomplete soil cleaning. In order to solve the above problems, the present application proposes a device for cleaning soil in pile holes on site for construction projects. Utility Model Content
