Abstract

The invention relates to a fault fracture zone gravel and water discharging device used for tunnel construction. A structure of the device comprises a tunnel floor, a soil layer and gravel and water discharging devices, wherein a lower surface of the tunnel floor and an upper surface of the soil layer are laminated, lower ends of the gravel and water discharging devices are installed in the soil layer in an embedded mode, through water collecting pits, water flows ooze from fault fracture zones of a tunnel are collected, then water pumping pipes are used for discharging the water flows in thewater collecting pits to make ponding in the tunnel maintained in a controllable range, meanwhile, rotating pit bottom turntables and stone discharging belts on the bottoms of the water collecting pits are used for discharging and collecting gravel which falls into the water collecting pits along with the water flows to prevent accumulation of the gravel in the water collecting pits, and thus notonly is required capability of the water collecting pits maintained, but also barrier of the gravel to water pumping of the water pumping pipes is reduced, so that the water collecting pies have enough water discharging speed in stages with large water yields on rainy days.

Description

technical field [0001] The invention relates to a rock discharge device for a fault fracture zone used in tunnel construction, and relates to the field of tunnel construction drainage. Background technique [0002] For the drainage of tunnel construction, by setting up multiple sumps in the tunnel, the accumulated water in the sumps is drained out of the tunnel with a water pump, and the water is pumped to the sewage sedimentation treatment tank outside the tunnel for collection and treatment by means of relay, so as to prevent the tunnel from The internal accumulation of water endangers the construction safety and corrodes the equipment in the cave. [0003] However, when the tunnel sump collects water, it is easy for the crushed stones produced by the tunnel construction to fall in and deposit at the bottom, which affects the pumping capacity of the suction pipe at the bottom of the sump, and affects the capacity of the sump under a large amount of deposition. In the peri...
