Abstract
The utility model discloses a kind of subway station open-cut foundation ditch precipitation well water reutilization system, after the water solved in existing dewatering well is extracted into ground, carry out the problem of discharging the water resource waste caused.Comprise subway station open-cut foundation ditch (1), dewatering well (2) is provided with in subway station open-cut foundation ditch (1), the mouth of pipe that draws water of suction pump (3) is arranged in dewatering well (2), the effluent pipe mouth of suction pump (3) and the water inlet of sedimentation and filtration pond (4) are connected together, the delivery port of sedimentation and filtration pond (4) is provided with water pump (5), the delivery port of water pump (5) and the water inlet of water tower (6) are connected together, the delivery port of water tower (6) is provided with water pressurized equipment (7), the delivery port of hydraulic pressure pressurized equipment (7) is connected with construction site and uses waterpipe (8) temporarily.Save site construction water, the underground water that dewatering well is extracted out obtains and recycles.
Description
Technical field
The utility model relates to ponding in a kind of Metro station excavation and extracts rear reclaiming system out.
Background technology
Generally all dewatering well is provided with, for being assembled by the underground water in foundation ditch in the open-cut foundation ditch of subway station.Normally carry out to make every construction in foundation ditch, discharge after generally the water in dewatering well being extracted into ground, meanwhile, in work progress, various construction needs a large amount of municipal water supplies to supply with water temporarily, and the water extracted out in dewatering well can reach the demand that water is used in many constructions temporarily, this way of supplying water not only causes the waste of water resource, and directly increases the cost of interim water of constructing.
Summary of the invention
The utility model provides a kind of subway station open-cut foundation ditch precipitation well water reutilization system, carries out the technical problem of discharging the water resource waste caused after the water solved in existing dewatering well is extracted into ground.
The utility model solves above technical problem by the following technical programs:
A kind of subway station open-cut foundation ditch precipitation well water reutilization system, comprise subway station open-cut foundation ditch, dewatering well is provided with in the open-cut foundation ditch of subway station, the drinking-water pipe of suction pump is arranged in dewatering well, the outlet pipe of suction pump is communicated with the water inlet in sedimentation and filtration pond, the delivery port in sedimentation and filtration pond is provided with water pump, the delivery port of water pump is communicated with the water inlet of water tower, the delivery port of water tower is provided with water pressurized equipment, and what the delivery port of hydraulic pressure pressurized equipment was connected with construction site uses waterpipe temporarily.
Because subway station space enclosing structure constructs interim water supply volume greatly, and municipal water supply unit price is high, and by utilization of the present utility model, save site construction water, the underground water that dewatering well is extracted out obtains and recycles.
Accompanying drawing explanation
Fig. 1 is the structural representation of utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail:
A kind of subway station open-cut foundation ditch precipitation well water reutilization system, comprise subway station open-cut foundation ditch 1, dewatering well 2 is provided with in subway station open-cut foundation ditch 1, the drinking-water pipe of suction pump 3 is arranged in dewatering well 2, the outlet pipe of suction pump 3 is communicated with the water inlet in sedimentation and filtration pond 4, the delivery port in sedimentation and filtration pond 4 is provided with water pump 5, the delivery port of water pump 5 is communicated with the water inlet of water tower 6, the delivery port of water tower 6 is provided with water pressurized equipment 7, the delivery port of hydraulic pressure pressurized equipment 7 is connected with the interim waterpipe 8 of construction site.
Can connection construction building site land clearing pipeline on the interim waterpipe 8 of construction site, also can link together with job site concrete curing water supply line, the water supply webmaster simultaneously also can constructed with space enclosing structure links together.
