The embodiment of the application discloses underground aquifer drainage system.

Referring to fig. 1, a groundwater aquifer 100 drainage system includes a drainage assembly 1 and a pump 2.

After the workers have found the location of the underground aquifer 100, they then drill a well at the job site that is accessible to one person. The well is then entered by a human operator who transports the drainage assembly 1 to the human operator in the well, who removes the drainage assembly 1 from the well after it has been installed in the aquifer 100, and the pump 2 may be a mud pump or other pump capable of pumping a mixture of water and silt. The pump 2 pumps the mixture of water and silt in the aquifer 100 to the ground, and the pile hole 200 is not easy to collapse after the mixture of water and silt in the aquifer 100 is pumped.

Referring to fig. 2 and 3, the drain assembly 1 includes a plurality of first drain pipes 11, an elbow pipe 12, and a second drain pipe 13. The circumferential outer walls of the first and second water discharge pipes 11 and 13 in the axial direction are provided with thread portions 111, and the outer walls of the pipe orifices at the two ends of the elbow pipe 12 are also provided with thread portions 111. An internally threaded pipe 14 is threadedly coupled to one of the threaded portions 111 of the first drain pipe 11, and an internally threaded pipe 14 is also threadedly coupled to one of the threaded portions 111 of the elbow 12. The adjacent first drainage pipes 11 are connected by the internal threaded pipe 14, the bent pipe 12 is connected with the first drainage pipes 11 by the internal threaded pipe 14, and the bent pipe 12 is connected with the second threaded pipe by the internal threaded pipe 14.

The staff installs many first calandrias 11 as required, and subaerial staff transports first calandria 11 to the staff in the well, and the staff in the well does not have threaded connection internal thread pipe 14 with first calandria 11 one end and injects in the aquifer 100, then connects many first calandrias 11 in proper order, rotates internal thread pipe 14 and links together two adjacent first calandrias 11. After the first drainage pipe 11 is installed, the elbow 12 is conveyed to the well by an operator on the ground, the elbow 12 is connected with the internal thread pipe 14 on the first drainage pipe 11 by the operator in the well, the internal thread pipe 14 is rotated to lock the elbow 12, and the pipe orifice of one end of the elbow 12, which is in threaded connection with the internal thread pipe 14, faces the ground. Then, the second drain pipe 13 is conveyed into the well by the above-ground worker, the second drain pipe 13 is in threaded connection with the internal threaded pipe 14 on the elbow 12 by the well worker, and the internal threaded pipe 14 on the elbow 12 is rotated to tightly push the second drain pipe 13.

After the installation of drainage assembly 1 is completed, the staff in the well returns to above ground, the staff is connected pump 2 and second drain pipe 13 through the ring flange, pump 2 pumps the mixture of water and silt in aquifer 100 to subaerial, and after the mixture of water and silt in aquifer 100 is pumped out completely, pile hole 200 is difficult to produce and sinks.

Referring to fig. 2, since the wrinkled portion 112 is more fragile than other portions of the first drain pipe 11, the wrinkled portion 112 may be crushed in the aquifer 100 and deformed, thereby affecting the drainage effect, and the reinforcing sleeve 6 is slidably connected to the circumferential outer wall of the first drain pipe 11 so that the wrinkled portion 112 is not easily deformed by pressure. The reinforcing sleeve 6 protects the corrugated portion 112 so that the corrugated portion 112 is not easily deformed when subjected to a pressure. Due to the sliding connection of the reinforcing sleeve 6 with the first drain pipe 11, the reinforcing sleeve 6 may slide out of the corrugated portion 112, thereby exposing the corrugated portion 112 to deformation under pressure. The baffle 7 is fixedly connected to the circumferential outer wall of the first drainage pipe 11, the axis of the first drainage pipe 11 is perpendicular to the baffle 7, and the baffle 7 is located between the corrugated portion 112 on the first drainage pipe 11 and the internally threaded pipe 14. When a worker in the well inserts the first drainage pipe 11 into the aquifer 100, the corrugated part 112 is blocked by the reinforcing sleeve 6, and the baffle 7 blocks the reinforcing sleeve 6 in the process of moving the first drainage pipe 11, so that the reinforcing sleeve 6 is not easy to separate from the corrugated part 112.

Referring to fig. 1, a collapse may occur where the first drain pipe 11 and the bent pipe 12 are inserted into the aquifer 100, and a reinforcement plate 4 is fixedly coupled to a circumferential side wall of the bent pipe 12 in order to stabilize the first drain pipe 11 and the bent pipe 12 in the aquifer 100. After the elbow 12 is installed by a worker in the well, the reinforcing plate 4 is inserted into the inner wall of the well, and the reinforcing plate 4 enables the elbow 12 to be firmer in the well. The pump 2 is more stable in the drain assembly 1 when in operation.

Referring to fig. 2, in order to improve the sealing performance of the drainage assembly 1, a pipe opening fixedly connected with sealing gasket 5 of the internal thread pipe 14 is arranged on the first drainage pipe 11, a pipe opening fixedly connected with sealing gasket 5 of the internal thread pipe 14 is arranged on the bent pipe 12, when two adjacent first drainage pipes 11 are connected, the first drainage pipe 11 abuts against the sealing gasket 5, when the second drainage pipe 13 is connected with the bent pipe 12, the second drainage pipe 13 and the bent pipe 12 abut against the sealing gasket 5, and therefore the pump 2 is not prone to leakage when pumping water and a mixture of silt.

Referring to fig. 3, the pump 2 may clog the drainage assembly 1 while pumping the water and sediment mixture of the aquifer 100. In order to facilitate the dredging of the first drain pipe 11, the bend 12 or the second drain pipe 13. The second water discharge pipe 13 is communicated with a branch pipe 8, the branch pipe 8 is positioned at one end of the second water discharge pipe 13 close to the pump 2, and the branch pipe 8 is also in threaded connection with a sealing cover 9. When the blockage occurs, the worker rotates the sealing cover 9 to remove the sealing cover 9, and then inserts a rod or the like into the branch pipe 8 or pressurizes the second drain pipe 13 to dredge the blocked position.
