Description

Technical Field

[0001] The utility model relates to a relay drainage device for vertical shaft construction in water-rich areas, belonging to the field of vertical shaft drainage tools. Background Art

[0002] When building a vertical shaft in a water-rich area, the risk of water accumulation at the bottom of the shaft is extremely high during construction. During the construction of the vertical shaft, the fissure water flows along the shaft wall to the excavation face, causing water accumulation on the face, which seriously affects the excavation and support work of the vertical shaft. When the vertical shaft is shallow, the use of a water pump with a larger head can solve the problem of water accumulation at the bottom of the shaft. However, as the depth of the vertical shaft increases, it is very difficult to drain the bottom of the vertical shaft due to the limitation of the water pump head.

[0003] Therefore, there is a need for a drainage device for vertical shaft construction in a water-rich area, which can drain the vertical shaft in the construction project and avoid affecting the construction process. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a relay drainage device for vertical shaft construction in water-rich areas, which can drain the vertical shaft in the construction project and avoid affecting the construction process; it can overcome the shortcomings of the existing technology.

[0005] The purpose of this utility model is achieved through the following technical solutions:

[0006] The utility model discloses a relay drainage device for vertical shaft construction in a water-rich area, which comprises a vertical shaft body, water collecting troughs are arranged on the inner wall of the vertical shaft body from top to bottom, a water retaining wall is arranged outside the water collecting trough, a water pump is arranged in the water collecting trough, a drainage pipe connected to the ground surface is arranged on the water pump, and an automatic switch capable of automatically draining water according to the water level is arranged in the water collecting trough.

[0007] The above-mentioned automatic switch includes a guide rod arranged in the water collection tank, a float box capable of moving up and down along the guide rod is arranged on the guide rod, a fixed first magnetic sheet is arranged at the upper end of the guide rod, a second magnetic sheet capable of moving up and down along the guide rod is arranged on the guide rod, a first touch sheet and a second touch sheet are respectively arranged on the first magnetic sheet and the second magnetic sheet, the first touch sheet and the second touch sheet contact or separate with each other to control the start or shut down of the water pump, and a traction rope connected to the second magnetic sheet is arranged on the float box.

[0008] As mentioned above, a horizontal annular groove communicating with the water collecting trough is provided on the inner wall of the vertical shaft body.

[0009] As mentioned above, a lining layer is provided in the shaft body.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The utility model can collect the flowing water on the side wall of the shaft body in sections through the segmented water collecting trough, and then pump it up through the water pump to realize the extraction of the accumulated water, thereby avoiding the influence on the construction surface. Through the automatic switch, when the water in the water collecting trough reaches a certain level, it can be automatically extracted without the need for workers to monitor the water level.

[0012] 2. The automatic switch includes a guide rod provided in the water collection tank, a buoyancy box capable of moving up and down along the guide rod, a first fixed magnetic sheet provided at the upper end of the guide rod, a second magnetic sheet capable of moving up and down along the guide rod, a first touch sheet and a second touch sheet provided on the first magnetic sheet and the second magnetic sheet, respectively, the first touch sheet and the second touch sheet contact or separate with each other to control the start or shut down of the water pump, a traction rope connected to the second magnetic sheet provided on the buoyancy box, connected to the live wire connected to the power supply through the first touch sheet and the second touch sheet, respectively, and the power supply, the live wire, the neutral wire, the first touch sheet and the second touch sheet are connected to the live wire connected to the power supply through the first touch sheet and the second touch sheet. The closure between the two touch plates can form a closed circuit, thereby controlling the power supply to the water pump and starting water pumping. More specifically, as the water level rises due to the accumulation of water, the float box moves upward along the guide rod. When the first magnetic plate and the second magnetic plate contact each other due to suction, the first touch plate and the second touch plate contact each other, thereby starting the water pump to pump water. As the water level drops, the float box moves downward along the guide rod, and the traction rope is continuously tightened. As the water level continues to drop, the second magnetic plate is separated from the first magnetic plate due to the pulling of the traction rope, thereby stopping the water pump from pumping water, and the second magnetic plate falls back onto the float box.

[0013] 3. A horizontal annular groove connected to the water collecting tank is arranged on the inner wall of the shaft body, so that water can be led to the water collecting tank in sections around the inner wall of the shaft body through the horizontal annular groove.
