CN2775147Y - Blocking structure for anti-dirty water for well - Google Patents

Abstract

The utility model relates to a ground dirty water penetration prevention structure for a water well, which is composed of an outer wall (16) at the upper part of a steel cement sleeve pipe (11), an inner wall (8) of a water well and blocking materials (7) between the outer wall of the steel cement sleeve pipe and the inner wall of the water well, wherein the blocking materials (7) are seaweed or palm sheets, and correspond to a shale layer (13). The lower surface of the shale layer is a rice stone (10), and the upper surface of the shale layer is provided with concrete (6). The steel cement sleeve pipe (11) is formed by welding a plurality of sleeve pipes, wherein the middle part of the steel cement sleeve pipe has a plurality of water penetration holes (9) which correspond to a water containing layer (14). Clean water in the water containing layer (14) enters the well, namely the steel cement sleeve pipe (11), through the rice stone (10) and the water penetration holes (9). Because the blocking materials (7) are the seaweed or the palm sheets, the blocking materials (7) are expanded because of water, the condition that dirty water on the ground penetrates into the water containing layer (14) along a gap between the outer wall (16) of the steel cement sleeve pipe (11) and the inner wall (8) of the water well can be effectively blocked, and the water quantity in the water well can be ensured. The utility model is a ground dirty water penetration prevention structure for a water well, which is widely used for urban and rural residents' drinking water.

Description

Well bilge water resisting plugging structure

Technical field

The utility model relates to a kind of plugging structure that is used for the infiltration of well bilge water resisting.

Background technology

As everyone knows, generally beat and drink well, all will pass the unconsolidated formation on ground, middle rammell is to following aquifer water intaking.In order to guarantee the quality of drinking water WIH, prevent that ground sewage from permeating between the inwall of the outer wall on steel cement sleeve pipe top and well, pollute the water source in aquifer, the method that people adopt usually is to add filler compactings such as one deck such as braid over braid, fiber crops, straw between the outer wall on steel cement sleeve pipe top and well inwall, uses the concrete capping above.But because concrete is easy to crack, ground sewage leaks down by the crack, and fillers such as braid over braid, fiber crops, straw through water is long-time soak after, perishable, plugging effect is bad, but also has further polluted the water source.

The utility model content

The purpose of this utility model provide a kind of can prevent effectively, reliably, enduringly ground sewage by steel cement sleeve pipe top outer wall and the inwall of well between immerse underground plugging structure.

The purpose of this utility model is achieved in that

A kind of well bilge water resisting plugging structure, by steel cement sleeve outer wall, well inwall and between filler constitute, described filler is the plugging material that stops the water infiltration, the described plugging material of plugging material is sea-tangle or brown sheet.

The utility model as sea-tangle or brown sheet, has been placed a layer concrete owing to placed one deck plugging material between steel cement sleeve pipe top and well inwall rammell part above the plugging material, even concrete cracking or other reason, ground sewage is along under the infiltration of crack, and after sea-tangle or brown sheet were met water, volume will expand tempestuously, can be effectively and shutoff crack reliably, sea-tangle sewage can not permeated down, owing to can survive growth in water, imputrescibility prolongs the time of shutoff greatly.And sea-tangle also played and filtered and the effect of clarification sewage, so ground sewage can not guarantee that the drinking water in the well cleans by being penetrated in the aquifer between steel cement sleeve outer wall and the well inwall, can not polluted.

Description of drawings

Fig. 1 looks sectional view for master of the present utility model.

The specific embodiment

With reference to the accompanying drawings the utility model embodiment is described further below.

In Fig. 1, well top is outwards conical, and the middle and lower part is cylindrical, and a length is dark in identical steel cement sleeve pipe 11 erectly is placed in the well with one heart with well, and pipe of cement 5 is placed on the conical end on well top with one heart.Well passes ground unconsolidated formation 12, rammell 13 and aquifer 14.Steel cement sleeve pipe 11 is welded by many sleeve pipes, there are many permeable holes 9 corresponding around the middle part of steel cement sleeve pipe 11 with the position in aquifer 14, between the external surface 16 of steel cement sleeve pipe 11 and well inwall 8 with a rice stone 10, fill out the rammell 13 from the shaft bottom always, the rice stone 10 of grain of rice size can flow through the water in the aquifer 14 unobstructedly, and the granule foreign in the energy filtered water, permeable hole 9 through steel cement sleeve pipe 11 middle parts enters in the steel cement sleeve pipe 11 then, on rice stone 10, be with one deck plugging material 7, under the sewage permeation that prevents ground between the rammell 13 of the outside 16 of steel cement sleeve pipe 11 and well inwall 8.Plugging material 7 can be with sea-tangle or brown sheet, and according to the actual conditions of shutoff, the thickness of shutoff can reach 30-60cm.Sea-tangle or brown sheet can be placed respectively, also can intersect placement.Then, be with concrete 6 cappings on plugging material 7 between the outer surface of upper 16 of steel cement sleeve pipe 11 and the pipe of cement 5.Pipe of cement 5 external surfaces and well conical surface are are also filled and led up with concrete 4.Raised platform around a well 3 is set on the pipe of cement 5, seals the well mouth with well lid 1 then.When ground sewage passes through ground unconsolidated formation 12, or permeate following time by the crack that concrete 6 produces, sea-tangle or brown sheet are by water saturates, expand rapidly then, crack around having blocked, the outer wall 16 and the ground sewage between the well inwall 8 of steel cement sleeve pipe 11 can not permeated down, played the effect of shutoff ground sewage.And sea-tangle can survive in water, imputrescibility, so the quality height of shutoff, effective, the shutoff time is long.And sea-tangle has also played filtration and the effect of clarification sewage.Therefore, guaranteed in the well, be water in the steel cement sleeve pipe 11 all from aquifer 14, improved the quality of water WIH.During water intaking, the end of water pipe 2 is connected with water pump 15, puts it in the steel cement sleeve pipe 11, just the source, water source in the well constantly can be extracted into ground and use for people and animals.

Claims (3)

1, a kind of well bilge water resisting plugging structure, by steel cement sleeve outer wall (16), well inwall (8) and between filler constitute, it is characterized in that: described filler is the plugging material (7) that stops the water infiltration, and plugging material (7) is corresponding with rammell (13).
