Description
Technical field
The invention belongs to Geological Engineering technical fields, are related to a kind of influent well, especially a kind of to convert high concentration of sediment river water
For the seepage flow well construction of underground water.
Background technology
Infitration galleries (gallery) and to be close to river pipe well, large-diameter well, radial be traditional water intaking for converting river water to underground water
Method is to excite the supply of river surface water leakage to increase the water-supply method of individual well water withdrawal by river valley area phreatic aquifer,
It is primarily suitable for the river river valley area that the small sedimentary particle of silt content is pure, water penetration is strong, by the high permeability for rushing diluvial formation
River big intensity supply is obtained, and river load content is small does not generate sediment siltation substantially and block, can continuously convert river
Water realizes lasting water intaking.But infitration galleries (gallery) and it is close to river pipe well, large-diameter well, radial these method for fetching water in high concentration of sediment river
It flows river valley area and fetches water effect with regard to phase strain differential, fully-loaded stream river valley area will be not suitable for excite the water intaking side of river surface water
Formula, this is because to rush proluvial thickness of deposits typically small for fully-loaded stream river valley area, in river deposit shale content also compared with
The water penetration of height, water-bearing layer is not generally strong, is fetched water using river pipe well, large-diameter well, radial mode is close to, the supply model influenced
Enclose small, water withdrawal will be extremely limited, it is difficult to meet water intaking water demand；It is fetched water using infitration galleries (gallery) method, though it can pass through
Increase length to increase supply range, but the sand gravel artificial water-bearing layer strong by riverbed backfill water penetration is excavated, not only seriously breaks
Bad riverbed superficial form and lower part aquifer structure, since river load content is high, the silt in river surface water also will be serious
Block artificial water-bearing layer so that the permeability in artificial water-bearing layer drastically reduces water withdrawal and substantially falls sharply and cause infitration galleries water intake engineering
Long-term water supply purpose is not achieved, this is particularly acute in the fully-loaded stream river valley area in northwest China area, and infitration galleries excavates deep in addition
Degree limitation generally can not reach in underlying stratum so that infitration galleries foundation construction is unstable to be added as provisional method for fetching water
To utilize.And these water-supply methods will expose water-bearing layer from top to bottom from water intaking location water-bearing layer earth's surface, this will necessarily be deposited
The drawbacks of destroying riverbed location surface configuration and phreatic aquifer structure.Therefore, it is necessary to explore a kind of novel break the normal procedure
Method for fetching water exactly converts high concentration of sediment river water to the novel of underground water especially in northwest China fully-loaded stream River Valley Region
Influent well method for fetching water, the drawbacks of overcoming infitration galleries (gallery) and be close to the method for fetching water such as river pipe well, large-diameter well, radial, to expire
Demand of the foot length phase stable water supply to water source construction.
