A water filter pit and its application

Abstract

The invention discloses a water-draining residue soil collecting pit and application thereof. The water-draining residue soil collecting pit comprises a residue soil collecting pit bottom plate and a residue soil collecting pit side wall, and further comprises water collecting joints and water pumping equipment. The residue soil collecting pit side wall is provided with water collecting holes at intervals; each water collecting hole comprises an inner end and an outer end; and the water collecting holes are formed in the lower portion of the side wall. The water collecting joints are arranged in the water collecting holes of the water collecting pit side wall at intervals and used for collecting water in residue soil. The water pumping equipment is communicated with the water collecting joints through connecting pipes, and used for discharging water in the connecting pipes to a draining pipe which is connected with the water pumping equipment. By the water collecting joints arranged in the lateral wall of the residue soil-collecting pit, water in the residue soil collecting pit can be pumped in time by the water pumping equipment in time, water content of residue soil is lowered, transportability and disposal of residue soil are improved, transportation work amount is reduced, and transport cost is lowered. Water pumped from the residue soil collecting pit is treated into water for dust settling on construction sites, flushing toilets, synchronous grouting or slurry preparing and the like, so that the water resource is saved while the construction cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of shield tunneling, and in particular relates to a filter water collection pit and its application. Background technique [0002] As the most advanced super-large special equipment for tunneling today, the shield machine is a high-tech construction equipment that realizes excavation, excavation, support, etc., and is widely used in urban rail transit, railways, highways, municipal administration, hydropower, etc. tunnel Engineering. [0003] During the construction of the earth pressure balance shield, as the shield machine excavates, the rock and soil cut by the cutter head are mixed with the improved materials and are continuously conveyed to the muck truck through the screw conveyor and belt, and then transported to the ground by the electric locomotive and the gantry crane In the soil collection pit, it will be transported by earth truck to the city's designated spoil ground. In the past, the moisture...
