Description
Technical field
The present invention relates to a kind of base pit dewaterings, specifically, being a kind of base pit dewatering and interim waterworks for firefighting one
Change construction method.
Background technique
In the Sixian County home Hong Yun work of renovating shantytowns projects, 10 main buildings are 27/32 story shear wall construction, and water level buries
Deeply in 1.00m-2.20m, excavation of foundation pit depth is 5 meters.Since level of ground water is shallower, have an impact to construction.According to Suzhou Area
Building experience carries out dewatering construction using pipe well points.Cell library equipped with volume be 900 cubes of fire cistern, and it is corresponding
Fire pump room.In main body and secondary structure construction stage, mainly there are structure construction working face, scene spray, living area with water spot
Lavatory etc..If do not considered, using well-points dewatering, construction water can only pay water rate according to local operating service industry with water.
Therefore known well-points dewatering be not utilized and construction water expense there are problems that it is above-mentioned various inconvenient and.
Summary of the invention
The purpose of the present invention is to propose a kind of saving water resource and the scene of reducing is temporarily with the foundation pit of the investment of drainage facility
Precipitation and interim waterworks for firefighting integral construction method.
To achieve the above object, the technical solution of the invention is as follows:
Well-points dewatering, is discharged into cell by mud settling tank by a kind of base pit dewatering and interim waterworks for firefighting integral construction method
Fire cistern, the formal fire pump of installation cell and fire_fighting pipe network send each water spot water, it is characterised in that including following step
It is rapid:
A, dewatering construction unit connects each dewatering well in foundation pit periphery, establishes the water-supply-pipe from dewatering well to fire cistern
Road, including valve, mud settling tank, fire cistern；The precipitation well pump being arranged by dewatering well will by mud settling tank by well-points dewatering
Base pit dewatering is discharged into cell fire cistern；
B, the formal fire pump of fire-fighting unit in charge of construction installation cell and fire_fighting pipe network, floor standpipe are up pacified with main body construction
Dress；
C, the formal fire pump of installation cell and fire_fighting pipe network, send water to each and use water spot；
D, interim water system is combined with formal firewater system.
Base pit dewatering of the invention and interim waterworks for firefighting integral construction method can also use technology below
Measure further realizes.
Method above-mentioned, wherein the hydraulic pipeline further includes filter, filter is arranged in fire cistern and fire water
Between pump.
Method above-mentioned, wherein the filter is y-type filter.
Method above-mentioned, wherein the fire pump is temporarily used than commonly, water pump power is big, lift is high.
After adopting the above technical scheme, base pit dewatering of the invention and interim waterworks for firefighting integral construction method have
It has the advantage that
1, base pit dewatering system is conveniently connected with interim waterworks for firefighting；
2, it is discharged into fire cistern after live well-points dewatering filtering, formal fire cistern reservoir storage is big, and fire pump is more interim than common
With water pump power is big, lift is high, facilitate project water；
3, reducing project, with the investment on drainage facility, reduces engineering cost temporarily.

Specific embodiment
With reference to embodiments and its attached drawing further explains the present invention.
Embodiment 1
Referring now to Fig. 1, base pit dewatering system and interim waterworks for firefighting structural schematic diagram of the Fig. 1 for the embodiment of the present invention.
Well-points dewatering, is discharged into cell by mud settling tank by base pit dewatering and interim waterworks for firefighting integral construction method of the invention
Fire cistern, the formal fire pump of installation cell and fire_fighting pipe network send each water spot water, comprising the following steps:
A, dewatering construction unit connects each dewatering well in foundation pit periphery, establishes from three dewatering wells 1 to the defeated of fire cistern 5
Water lines, including valve 3, mud settling tank 4, fire cistern 5；The precipitation well pump 2 being arranged by dewatering well passes through well-points dewatering
Base pit dewatering is discharged into cell fire cistern by mud settling tank.Hydraulic pipeline further includes y-type filter 9, and y-type filter is arranged in fire-fighting
Between pond and fire pump.
B, the formal fire pump 6 of fire-fighting unit in charge of construction installation cell and fire_fighting pipe network, fire water standpipe 7, floor fire-fighting are vertical
Pipe is up installed with main body construction.
C, the formal fire pump of installation cell and fire_fighting pipe network, send water to each and use water spot；Fig. 2 is the embodiment of the present invention
Fire hydrant arrangement schematic diagram of the waterworks for firefighting in each floor.
D, interim water system is combined with formal firewater system.
The present invention has substantive distinguishing features and significant technological progress, base pit dewatering of the invention and interim fire fighting supply system
