Background technology
At present, national large area carries out underground pipe gallery project construction, as construction enterprises, at the beginning of underground pipe gallery is built
Exactly piping lane groove is excavated, scope involved by ultra-large type piping lane is to reach that below 8m, piping lane bottom width reach in depth
In the range of to more than 7m.The construction of this kind of piping lane groove not only should be noted that level of ground water is soaked to piping lane in channel excavation
Influence, while it is also noted that the influence of sleet sky precipitation.Piping lane before civil engineering it has to be ensured that piping lane ground it is close
Solidity, this is accomplished by us and takes measures to carry out water in piping lane groove outer arrange.Water in the piping lane groove of prior art
Outer row, using the methods such as open caisson, expensive, the DeGrain of generation.
The content of the invention
The purpose of the present invention is the deficiency for existing product, and provides a kind of raising precipitation efficiency, protects piping lane civil engineering
Construction and a kind of ultra-large type piping lane groove construction precipitation system of later stage piping lane operation safety.
The present invention a kind of ultra-large type piping lane groove construction precipitation system, the Dewatering system include catch pit, thoroughly
Water drum, protective cradle, submersible sewage pump, liquid-level floater controller, flexible pipe, check-valves, branch drain, drain header, the catch pit
Inside being provided with the water in permeable cylinder, catch pit can be entered in cylinder by permeable cylinder, and protective cradle, submersible sewage pump are provided with permeable cylinder
It is fixed in cylinder on protective cradle；Switch controller is provided with the submersible sewage pump, the switch controller and liquid level are floating
Ball controller is connected, and the delivery port of the submersible sewage pump is connected to flexible pipe, and the front end of the flexible pipe is provided with check-valves, the check-valves
With branch drain connection, branch drain and the drain header connection, the drain header and municipal rainwater or bilge well connect
Connect.
The Dewatering system sets a set of in ultra-large type piping lane groove every 30m, each Dewatering system
The switch controller of submersible sewage pump is connected by wire and programmable controller.
The beneficial effects of the invention are as follows：Compared with prior art, the Dewatering system that the present invention is provided, in whole super large
In the water level monitoring and Precipitation Process of type piping lane groove, the purpose of real-time tracking, precipitation at any time, whole system running are realized
Precipitation is obvious, it is ensured that piping lane foundation compactness.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
In figure：Catch pit 1, permeable cylinder 2, protective cradle 3, submersible sewage pump 4, liquid-level floater controller 5, flexible pipe 6, check-valves 7,
Branch drain 8, drain header 9.
Embodiment
Below by specific embodiment, technical scheme is described in further detail, but the present invention is simultaneously
It is not limited to embodiment.
In figure, a kind of ultra-large type piping lane groove construction precipitation system of the invention includes catch pit 1, permeable cylinder 2, protection
Support 3, submersible sewage pump 4, liquid-level floater controller 5, flexible pipe 6, check-valves 7, branch drain 8, drain header 9.
A kind of ultra-large type piping lane groove construction precipitation system is used in the piping lane construction of Zhuhai City Hengqin island, and Hengqin island is integrated
13 kilometers of piping lane length, piping lane is in underground 8m positions, and piping lane the widest part reaches 17m.In the piping lane construction stage, due to rainwater and
Basement enriches, using above ultra-large type piping lane groove construction Rainfall Monitoring and precipitation system, the submersible sewage pump model used
AS55-2CB types, branch drain diameter DN125, drain header diameter DN400.In channel excavation work progress, in piping lane avris
Excavating the water laid in one long wide * depth=1 meter of * 1 meter of * 1.5 meters of catch pit 1 of *, catch pit in permeable cylinder 2, catch pit 1 can lead to
Cross permeable cylinder 2 to enter in cylinder, protective cradle 3 is provided with cylinder, submersible sewage pump 4 is fixed in cylinder on protective cradle 3.Submersible sewage pump 4
Power supply uses interim normal power source, and submersible sewage pump 4 is opened and closed to be controlled by the liquid-level floater controller 5 being connected with submersible sewage pump 4, dives
The dirty delivery port of pump 4 is connected to flexible pipe 6, and the length of flexible pipe 6 is in 300mm-500mm scopes, and the diameter of flexible pipe 6 is big according to regional areas displacement
Small to determine, the other end of flexible pipe 6 is provided with steel branch drain 8, branch drain 8 and is provided with check-valves 7.It is attached at the top of piping lane groove
Near to install steel drain header 9, branch drain 8 is connected with drain header 9.To ensure that the water discharged in groove is not produced to environment
Raw influence, typically introduces the delivery port of drain header 9 in municipal rainwater nearby or bilge well.To ensure ultra-large type piping lane groove
Precipitation is smooth, effect is obvious, and general each 30m sets a set of draining submersible sewage pump system.
Dewatering system sets a set of, the latent dirt of each Dewatering system in ultra-large type piping lane groove every 30m
The switch controller of pump 4 is connected by wire and programmable controller.The power of Controlled by Programmable Controller submersible sewage pump 4, works as liquid level
When float control 5 floats to peak, the power of submersible sewage pump 4 is opened to maximum.
When ultra-large type piping lane groove underground water or precipitation water level rise, water level in each catch pit 1 and permeable cylinder 2
Rise, water level, which rises, causes liquid-level floater controller 5 to float, liquid-level floater controller 5 starts submersible sewage pump 4 and started to catch pit 1
It is interior to be drawn water.The water of extraction flows into city planting ductwork by drain header 9, so as to reduce water level in piping lane groove.
