[0002] Groundwater has adverse effects on underground engineering. In many tunnel project construction and operation, especially in double-arch tunnel double-hole connection, the section is large, and drainage is much, tunnel leakage is almost inevitable. In the past, the tunnel leakage was often treated by directly discharging into the drainage ditch. However, this often causes inevitable soil erosion in the natural environment near the tunnel, and also causes waste of water resources. In the daily maintenance of the tunnel, the tunnel leakage cannot be utilized to achieve better utilization of water resources, and the collected leakage cannot be uniformly filtered and contains many impurities to block the pipeline. SUMMARY

[0016] The pressure relief valve can automatically open when the pressure in the equipment or pipeline exceeds the set pressure of the pressure relief valve, and automatically close when the pressure is lower than the set pressure; the filter pipe is connected to one side of the water flow outlet of the pressure relief valve, and is used for guiding and discharging the water discharged from the pressure relief valve to the lower part of the tunnel water layer, and can filter the water flow.

[0017] The double-layer nylon net is used for winding and wrapping the outer wall of the filter pipe, so as to prevent fine sand and the like from being discharged to the external environment with the water flow.

[0063] Example 3

[0064] Reference Figures 1-4 The third embodiment of the present application is different from the second embodiment in that the third embodiment provides a non-discharge multi-arch tunnel waterproof and drainage method and device.

[0065] Specifically, the storage mechanism 200 includes a water storage tank 201 connected to one end of the connecting pipe 103, a water valve 202 connected to one side of the water storage tank 201, and a water level meter 203 arranged on one side of the water storage tank 201.

[0068] The accumulated water in the storage mechanism 200 is discharged through the drainage mechanism 300.

[0069] Further, during use, the longitudinal water pipe 101 is connected to the ring drainage pipe A arranged in the tunnel during tunnel construction, the purified water tank 102 is installed at the partition wall, and the filter mat layer is correctly laid in the purified water tank 102, so that all the leakage water must pass through the filter layer before flowing into the water storage tank 201.

If the water valve 202 is not opened, the water in the water storage tank 201 will not flow out, and the water level in the water storage tank 201 will continue to rise, and the water pressure will also continue to increase, until the water pressure reaches the pressure value set by the pressure relief valve 302, the pressure relief valve 302 is opened, and the water in the water storage tank 201 flows into the filter pipe 303 through the drain pipe 301 and the pressure relief valve 302, and is discharged to the lower part of the tunnel water barrier layer after being filtered by the double-layer nylon mesh 304. After the water in the water storage tank 201 is discharged, the water pressure decreases.

The whole cycle is completed, and the water pressure increases again to the pressure set by the pressure relief valve 302, and the pressure relief valve 302 starts to work again. This process is repeated.

At the same time, it also has a positive effect on protecting the natural environment, reducing water and soil loss, and saving water resources.
