Description

A mobile tunnel construction relay pumping and drainage device

technical field

The utility model relates to the field of tunnel reverse slope construction, in particular to a mobile relay pumping and drainage device for tunnel construction.

Background technique

Tunnel construction generally includes tunnel construction projects such as roads, railways, water conservancy, and electric power. When a tunnel is constructed in a water-rich area, a large amount of groundwater will penetrate into the tunnel. Generally, 1 to 5 inclined shafts are set up in long tunnels, and the construction from the inclined shaft to the main tunnel is generally reverse slope construction, that is, the inclined shaft enters the main tunnel for construction, and a water tank (water collection well) is set at the intersection of the inclined shaft and the main tunnel. The water in the main hole is introduced into the water tank, and then the collected water in the water tank is discharged out of the inclined shaft in stages. Grading drainage generally needs to set up a sump in the inclined shaft. The setting of the sump is not only time-consuming and laborious, but also causes cross-flow of sewage due to untimely collection and drainage, which affects the construction environment in the cave.

Detailed ways

Below in conjunction with accompanying drawing description and specific embodiment, the utility model is described in further detail:

As shown in the figure, a mobile tunnel construction relay pumping and drainage device includes a water collection box 1, the water collection box 1 is connected with a water inlet pipe 2 and a drainage pipe 3, and the end of the water inlet pipe 2 far away from the water collection box 1 is connected to a water pump 15 connection, the bottom of the water collection tank 1 is provided with a submersible pump 7, the top of the submersible pump 7 is connected to the outlet pipe 3, and the side wall of the water collection tank 1 is provided with a control dial 8 for controlling the opening and closing of the submersible pump 7. The dial 8 is electrically connected to the low water level electronic water level switch 9 and the high water level electronic water level switch 10 in the water collecting tank 1 , and the bottom four corners of the water collecting tank 1 are provided with universal wheels 13 and wheel fastening devices 14 .

The side of the water collecting box 1 connected to the outlet pipe 3 is provided with a drain port 4 and an overflow port 5, the drain port 4 is at the bottom of the water collecting tank 1 side, and the overflow port 5 is at the top of the water collecting box 1 side.
