The good effect that the utlity model has: the extracting-recharge well that is applied to place polluted underground water reinstatement works of (1) the utility model both can be handled the underground water extracting of polluting to ground; Gather the underground water sample simultaneously; Also can clean tap water be poured in the well; Replenish underground water, accelerate the phreatic replacing velocity of polluting.Be specially adapted to the place of some high pollutions, geologic structure complicacy.(2) extracting that the is applied to place polluted underground water reinstatement works-recharge well water yield of the utility model is up to 8t/h～10t/h.
Description of drawings
Fig. 1 is the structural representation of the extracting-recharge well that is applied to place polluted underground water reinstatement works of the utility model.
Fig. 2 is the A portion enlarged drawing among Fig. 1.
The specific embodiment
(embodiment 1)
See Fig. 1 and Fig. 2, the extracting-recharge well that is applied to place polluted underground water reinstatement works of present embodiment comprises well casing 1, filler 2, extracting outlet pipe 3, recharges water inlet pipe 4, filter screen 5, flange 6, suction pump 7 and pressure meter 8.
Well casing 1 is the coating steel pipe of external diameter 0.325m, internal diameter 0.314m, and it is welded with the solid wall pipe 12 that is positioned at colored wall pipe 11 upper and lowers by flower wall pipe 11.Well casing 1 is total up to 20m, and wherein spending wall pipe 11 is 15m, and the solid wall pipe 12 of Hua Biguan top is 4m, and the solid wall pipe 12 of Hua Biguan below is 1m.The tube wall of flower wall pipe 11 is provided with some equally distributed treatment holes, thereby can intake.The tube wall of solid wall pipe 12 then can not be intake.
Filler 2 comprises quartz sand 21 and potter's clay 22, and quartz sand 21 is filled out between flower wall pipe 11 and the soil 9 and between the solid wall pipe 12 and soil 9 below the Hua Biguan, can let underground water pass through the quartz sand slit like this and get in the well casing 1.Potter's clay 22 is filled out between solid wall pipe above the Hua Biguan 12 and soil 9, can prevent that like this surface water around the well head from getting in the well casing 1.
The filter screen of being made up of 3 layer of 60 purpose nylon cloth 5 is wrapped in outside the colored wall pipe 11, is used for the silt of filtering underground.
Flange 6 is welded on well casing 1 top.Recharging water inlet pipe 4 is communicated with well casing 1 through this flange 6.Extracting outlet pipe 3 is communicated with well casing 1 through this flange 6, and the sample tap 31 of a band valve 31-1 also is installed on this extracting outlet pipe 3, takes a sample when being used for the underground water periodic monitoring.Pressure meter 8 is connected on this flange 6 through a short tube.Recharge on water inlet pipe 4 and the extracting outlet pipe 3 and be separately installed with valve 4-1 and 3-1, be used for the adjustment of extracting-between recharging.
