This structure is usually used during the construction of underground buildings to prevent groundwater from invading the construction area, ensure construction safety, and prevent excessive water pressure around the basement from squeezing the main body of the basement after it is built.
[0003] The basement dewatering vacuum deep well structure with the publication number CN215406137U includes a perforated steel pipe and a water pump. The perforated steel pipe is inserted below the basement floor slab. A steel mesh is sleeved on the outer wall of the perforated steel pipe. A gravel filling layer, a rapid-hardening cement layer, and a polyurethane grouting layer are successively arranged in the perforated steel pipe from bottom to top. An upper steel pipe is coaxially installed at the top of the perforated steel pipe, and the upper steel pipe is inserted into the perforated steel pipe; the upper steel pipe is buried in the basement floor slab layer. A first steel plate is welded and installed in the upper middle part of the upper steel pipe. A second steel plate is welded at the top of the upper steel pipe. Grouting material is filled below the first steel plate in the upper steel pipe, and micro-expansion concrete is filled between the first steel plate and the second steel plate; the water suction pipe of the water pump passes through the upper steel pipe and the perforated steel plate and is inserted into the gravel filling layer. The sealing effect of the technical solution of this patent is good, it is suitable for occasions with relatively large groundwater pressure, and the upper steel pipe can be recycled, saving costs.
[0004] The above patent improved the disadvantages that the plugging treatment of the deep well wellhead in the prior art is not good, and serious concrete slurry leakage and cavity phenomena are likely to occur, which will not only affect the strength and durability of the structure, but also cause concrete leakage, seriously affecting the normal use of the project. However, this technical solution uses a perforated steel pipe to drain and filter groundwater. When in use, the holes on the surface of the perforated steel pipe are in direct contact with the soil, which is likely to cause blockage of the holes, resulting in the inability to use the perforated steel pipe normally.

[0021] A vacuum pumping assembly is provided between the mounting plate 3 and the inner well 2.

A sealing cover 10 is fixedly installed at the top of the outer well 1. A first vacuum tube 11 communicating with the inner well 2 is fixedly installed at the air inlet end of the vacuum pump 8.

The water pump 9, the first water delivery pipe 13, and the second water delivery pipe 14 are used to pump the water in the inner well 2 out. When the water in the outer well 1 and the inner well 2 is too much, the water enters the overflow pipe 17, and the water pressure pushes the one-way valve 18 open, allowing the water to flow into the soil through the overflow pipe 17.

When the pressure reaches the set value, the vacuum pump 8 is started to pump vacuum.
