[0023] In the following, only some exemplary embodiments are briefly described to make the purpose, features and advantages of the utility model more obvious and understandable. As those skilled in the art will appreciate, the described embodiments can be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0024] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] like Figures 1 to 3 As shown, the utility model provides a pre-buried drainage well that can be used in a turnover manner, comprising: a steel column 1; the steel column 1 is used to connect a support beam 4 and a column supporting cast-in-place pile 5; a hollow portion is arranged in the steel column 1; a bellows mechanism 2; the bellows mechanism 2 is arranged in the hollow portion; a pumping and drainage mechanism 3; one end of the pumping and drainage mechanism 3 is arranged on the support beam 4, and the other end of the pumping and drainage mechanism 3 is connected to the bellows mechanism 2.

[0026] In this embodiment, the support beam 4 is the first support beam before casting, and the column supporting cast-in-place piles 5 can support the steel column 1. The support beam 4 and the column supporting cast-in-place piles 5 are both the original structures of the construction building; the two ends of the steel column 1 are respectively connected to the support beam 4 and the column supporting cast-in-place piles 5. Before the support beam 4 is cast, the prefabricated corrugated pipe mechanism 2 is buried in the hollow part of the steel column 1, and the upper and lower ends of the corrugated pipe mechanism 2 are respectively close to the bottom position of the support beam 4 and the top position of the column supporting cast-in-place piles 5; one end of the drainage mechanism 3 passes through and extends out of the upper surface of the support beam 4, and the other end is inserted into the corrugated pipe mechanism 2, and dewatering construction can be carried out; the pre-buried dewatering well can avoid on-site drilling construction of the dewatering well, and the used corrugated pipe mechanism 2 is easy to dismantle and can be continuously recycled, reducing construction costs and material waste.

[0027] Furthermore, a medium sand filling layer 6 is provided in the hollow portion; the medium sand filling layer 6 is connected to the steel column 1 and the bellows mechanism 2 respectively.

[0028] In this embodiment, the medium sand filling layer 6 is arranged in the hollow part of the steel column 1. The medium sand filling layer 6 can fill the gap between the corrugated pipe mechanism 2 and the inside of the steel column 1, thereby preventing the foundation pit soil from entering the hollow part and squeezing the corrugated pipe mechanism 2 to deform.

[0029] Furthermore, the bellows mechanism 2 includes: a bellows body 21, a nylon mesh and a tying wire; a plurality of holes 22 are evenly and densely distributed on the bellows body 21; the bellows body 21 is arranged in the hollow portion; the nylon mesh is wound around the bellows body 21; one end of the tying wire is connected to the bellows body 21, and the other end of the tying wire is connected to the nylon mesh.

[0030] In this embodiment, the length of the corrugated pipe body 21 is based on the distance from the top of the cast-in-place pile 5 supported by the on-site column to the bottom of the support beam 4. When the corrugated pipe mechanism 2 is prefabricated, two layers of nylon mesh are tied to the corrugated pipe body 21 using a wire, and the corrugated pipe body 21 is wrapped with nylon mesh and gauze. The wrapping range includes the upper and lower ends and all around the corrugated pipe body 21. After prefabrication, the corrugated pipe mechanism 2 is inserted into the hollow part of the steel column 1, with its lower end extending to the top of the cast-in-place pile 5 supported by the column, and the upper end extending to the bottom of the support beam 4, and then the gap is filled with a medium sand filling layer 6 to complete the installation.

[0031] Furthermore, the distance between the holes 22 is 50 mm; and the diameter of the hole 22 is 18 mm.

[0032] In this embodiment, the arrangement of the holes 22 on the corrugated tube body 21 can be determined according to the specific geological survey conditions. Otherwise, the holes 22 can be arranged in a uniform and dense manner with a diameter of 18 mm and a spacing of 50 mm, and the porosity is required to be not less than 30%, and there must be 2 circular holes with a diameter of 18 mm for every 25 square decimeters.

[0033] Furthermore, the diameter of the corrugated pipe body 21 is 300 mm, and the wall thickness of the corrugated pipe body 21 is 6 mm. The nylon mesh is a 60-mesh nylon mesh.

[0034] In this embodiment, the nylon mesh is a 60-mesh nylon mesh, and the corrugated tube body 21 is a corrugated tube with a diameter of 300 mm and a thickness of 6 mm.

[0035] Furthermore, the drainage mechanism 3 includes: a water pump 31 and a water pumping pipe 32; the water pump 31 is arranged on the support beam 4; one end of the water pumping pipe 32 is connected to the water pump 31, and the other end of the water pumping pipe 32 is arranged in the corrugated pipe body 21.

[0036] In this embodiment, the specific specifications of the water pump 31 are determined by the specific drainage demand on site, and it is equipped with an automatic switch for controlling the water level in the well, and a valve is installed at the wellhead to adjust the flow rate; the upper end of the pumping pipe 32 extends into the support beam 4 and is higher than the top surface of the beam by a certain distance to facilitate the connection of the water pump 31, and the lower end is inserted into the corrugated tube body 21, and the connection between the corrugated tube body 21 and the pumping pipe 32 is sealed.

[0037] Furthermore, the bottom of the water extraction pipe 32 is higher than the bottom of the corrugated pipe body 21. The distance between the bottom of the water extraction pipe 32 and the bottom of the corrugated pipe body 21 is D; and D is 0.5m to 1m.

[0038] In this embodiment, the bottom of the water pumping pipe 32 is higher than the bottom of the corrugated pipe body 21, and the distance between the bottoms of the two is 0.5 meters to 1 meter, thereby leaving space for water pumping.

[0039] Furthermore, a drainage pipe is also provided on the water pump 31 .

[0040] In this embodiment, after the water pump 31 is connected to the water pumping pipe 32, the water pump 31 is connected to the drainage pipe, and a test pumping is performed after the installation of the drainage mechanism 3 system is completed.
