Abstract
A kind of drainage of foundation pit pipeline be applied in building trade is vented from pressurization system, comprise supercharging standpipe, first Flange joint, turn to elbow, second Flange joint, horizontal short tube, conduit coupling, branch drain, stack, drain header road, dewatering well, supercharging riser bottom is connected with drain header road, supercharging riser upper is connected with turning to elbow by the first Flange joint, bend horizontal section is turned to be connected with horizontal short tube by the second Flange joint, horizontal short tube is connected by conduit coupling with branch drain, branch drain is connected with dewatering well, stack is connected with drain header road.This system, without the need to additionaling power, by utilizing the self gravitation of water to increase pressure for flowing line, can discharge the additional air in flowing line in time, reaches and improves the object of drainage effect, simple to operate, easy for installation and with low cost.
Description
Technical field
A kind of drainage of foundation pit pipeline that the utility model relates in building trade is vented from pressurization system.
Background technology
At present, in building trade super-giant foundation pit work progress, because drainage of foundation pit Trunk Line is long, cannot conveniently way carry out 3 ‰-5 ‰ and look for slope to lay, significantly can only reduce and put the slope gradient, drain header line almost horizontal is arranged, cause precipitation overpressure to diminish, and there is large quantity of air in pipe, cannot draining unobstructed, reduce row speed, affect drainage effect.Therefore, research and develop the exhaust of a kind of drainage of foundation pit pipeline is new problem anxious to be resolved from pressurization system always.
Summary of the invention
The purpose of this utility model is to provide a kind of drainage of foundation pit pipeline to be vented from pressurization system, this system is without the need to additionaling power, pressure is increased for flowing line by utilizing the self gravitation of water, and the additional air can discharged in time in flowing line, reach quickening flow rate, improve the object of drainage effect, simple to operate, easy for installation and with low cost.
The purpose of this utility model is achieved in that the exhaust of a kind of drainage of foundation pit pipeline is from pressurization system, comprise supercharging standpipe, first Flange joint, turn to elbow, second Flange joint, horizontal short tube, conduit coupling, branch drain, stack, drain header road, dewatering well, supercharging riser bottom is connected with drain header road, supercharging riser upper is connected with turning to elbow by the first Flange joint, bend horizontal section is turned to be connected with horizontal short tube by the second Flange joint, horizontal short tube is connected by conduit coupling with branch drain, branch drain is connected with dewatering well, stack is connected with drain header road.
Main points of the present utility model are its structure.Its operating principle is, this device is connected between drain header line and branch drain line, and the underground water extracted out by water pump, after this device, obtains that certain acceleration of gravity is laggard becomes owner of flowing line, accelerate flow rate, extrude air unnecessary in main discharge line simultaneously and discharge from stack.
A kind of drainage of foundation pit pipeline exhaust from pressurization system compared with prior art, there is system without the need to additionaling power, pressure is increased for flowing line by utilizing the self gravitation of water, the additional air in flowing line can be discharged in time, reach the object improving drainage effect, simple to operate, the easy for installation and advantage such as with low cost, will be widely used in building trade.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in detail.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
With reference to accompanying drawing, a kind of drainage of foundation pit pipeline exhaust is from pressurization system, comprise supercharging standpipe 1, first Flange joint 2, turn to elbow 3, second Flange joint 4, horizontal short tube 5, conduit coupling 6, branch drain 7, stack 8, drain header road 9, dewatering well 10, be connected with drain header road 9 bottom supercharging standpipe 1, supercharging standpipe 1 top is connected with turning to elbow 3 by the first Flange joint 2, elbow 3 horizontal segment is turned to be connected with horizontal short tube 5 by the second Flange joint 4, horizontal short tube 5 is connected by conduit coupling 6 with branch drain 7, branch drain 7 is connected with dewatering well 10, stack 8 is connected with drain header road 9.
