Description
Technical field
The utility model belongs to seepage well antiseepage field, is specifically related to a kind of shutoff antiseepage well.
Background technology
Increase fast along with regional economy, water head site ground water environment increasing pressure is large.Run into continuous dry years part, when artesian water water level is lower than groundwater level, in artificial string layer well location, the diving that top may be polluted very easily pollutes bottom artesian water, because karsts developing area is good, connectedness strong, its polluted-water will be rapidly to downstream or periphery diffusion, very easily causes water pollutions accident, affects water supply security.Top Quaternary system is dived under water and is easily formed potential pollution threat to bottom Ordovician karstic water, for this reason, needs to carry out Quaternary system diving Anti-seeping technology to these wells, does not also have well Quaternary system diving seepage control technique at present.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of shutoff antiseepage well, prevents Quaternary system water table aquifer water to be seeped in well, and realizes the segmentation of Quaternary system water table aquifer and karst aquifer, mutual non-cross strata.
Shutoff antiseepage well described in the utility model, well top is Quaternary system water table aquifer, well bottom is karst aquifer, well inside arranges steel pipe, steel pipe is divided into two sections, be respectively epimere steel pipe and hypomere steel pipe, epimere steel pipe is near Quaternary system water table aquifer, hypomere steel pipe is near karst aquifer, the diameter of epimere steel pipe is greater than the diameter of hypomere steel pipe, connected by reducing head between epimere steel pipe and hypomere steel pipe, the first sea-tangle winding layer is set gradually from down to up between hypomere steel pipe bottom and well inwall, rubber seal belt and the second sea-tangle winding layer, lining high pressure fire fighting water-band support will be had to be fixed on hypomere steel pipe top, outside reducing head and epimere outer wall of steel pipe, hole injecting paste material between steel pipe and well inwall is filled.
Well top is Quaternary system water table aquifer, and well bottom is karst aquifer, and well is greater than the diameter at karst aquifer at the diameter of Quaternary system water table aquifer.Epimere steel pipe welds with well well head place, prevents steel pipe from gliding before grouting reinforcement.In order to reach shutoff anti-seepage effect, the first sea-tangle winding layer, rubber seal belt and the second sea-tangle winding layer is set gradually from down to up between hypomere steel pipe bottom and well inwall, in order to reach better shutoff anti-seepage effect, the place partially overlapped at the karst aquifer of hypomere steel pipe bottom outside and this well with complete rock section arranges the first sea-tangle winding layer, rubber seal belt and the second sea-tangle winding layer, first sea-tangle winding layer and the second sea-tangle winding layer are and are wrapped on hypomere steel pipe by sea-tangle, then fix with iron wire; Rubber seal belt is rubber waterproof belt with expansion when in water; The effect arranging the first sea-tangle winding layer, rubber seal belt and the second sea-tangle winding layer is isolation injecting paste material.Lining high pressure fire fighting water-band support will be had to be fixed on outside hypomere steel pipe top, reducing head and epimere outer wall of steel pipe, that is, lining high pressure fire fighting water-band will be had to be stuck in outside hypomere steel pipe top, reducing head and epimere outer wall of steel pipe with support, lining high pressure fire fighting water-band is had to be hollow structure inside, during slip casting, slurry is carried out reflection slip casting, until the hole between steel pipe and well inwall is all filled with injecting paste material by there being lining high pressure fire fighting water-band to enter hypomere steel pipe place.
In sum, the utility model has the following advantages:
(1) the utility model provides a kind of antiseepage well, damaged mainly for water supply well wall protection pipe, the problem such as borehole wall seepage in water supply well fresh water, salt water shutoff and drilling process;
(2) the utility model effectively prevents from Quaternary system water table aquifer water to be seeped in well karst going, achieve Quaternary system water table aquifer and the mutual non-cross strata of karst aquifer complete parttion;
(3) the utility model will have lining high pressure fire fighting water-band to fix by support, adopt and will have lining high pressure fire fighting water-band reflective filler, effectively prevent filler from occurring the shortcoming such as honeycomb or the unreal seepage again of slip casting;
(4) the utility model sets gradually the first sea-tangle winding layer, rubber seal belt and the second sea-tangle winding layer from down to up between hypomere steel pipe bottom and well inwall, is environment-friendly products, can not cause secondary pollution to this well.
