Description
One, technical field
The present invention relates to a kind of soakaway trench; Especially a kind of water pipe of inside and outside infiltration drainage compatibility and preparation method.
Two, background technology
The proposition in sponge city is that the mankind produce nature and ecological thinking, comprising the theory of revering to the Nature, the construction in sponge city needs comprehensively to adopt " ooze, stagnant, store, only, with, row " etc. project slash, control urban rainwater river rising in Ningxia and flowing into central Shaanxi stream, realize low affect city development build (LID), reduce the destruction because city development behavior of building causes original natural hydrology characteristic sum water ecological environment to greatest extent, urban construction is become " cavernous body " of " naturally accumulation, naturally osmotic, self-purification ".Namely city is as sponge, run into when having rainfall can absorb on the spot or nearby, save, permeate, purifying rainwater, recharge of groundwater, regulate water circulation; Have ready conditions when drought and water shortage and the water stored discharged, and be used.
The construction in sponge city needs to ooze, stagnant, store, only, use, the engineering facility such as row, specifically comprise drainage waterlogging prevention facility, town sewage pipeline network construction, rain dirt shunting transformation, rainwater catchment system facility, reuse of wastewater, leakage loss pipe network improving etc., wherein ooze, stagnant, the source such as to store to rainwater utilization and reduction of discharging is most important part.In source, rainwater is oozed, stagnant, storing must combining road and place construction use drainage water pipe.
Existing filter pipe, can also prevent the particle of soil or rock around the borehole wall from flowing in well and silt well casing up except water inlet, also plays a part to support and the protection borehole wall simultaneously, and suction eye can normally be used.The charges that some hard crack, solution crack aquifer wellbore stability are unloose again, the Shi Buxu that draws water installs filter pipe, and loose Porosity Aquifer or the bedrock aquifer of fragmentation, must install applicable filter pipe.Also conventional cement gravel filter pipe in agriculture water supply well, the brick wood borehole wall of people's well has in fact also been drainage, the effect of resource of purifying waste water.Meanwhile, in large-scale national project, e.g., project of South-to-North water diversion, Olympic Games diving place-the Water Cube, thing conveying engineering etc., all will use and high-qualityly reach filter pipe.The kind of common filter pipe: cage (Johnson) filter pipe, netted filter pipe, filament wrapped filter pipe and gravel filter pipe in bridge-type water strainer, dragon.
Cutting seam sieve tube, punching screen casing, precise screen pipe, the wire-wrapped screen etc. of current petroleum industry application all also exist certain weak point.Cutting seam sieve tube, due to the reason of technology and cost aspect, slot width is greater than 0.15mm, and (plasma panel slot patented technology can reach the most I of 0.15mm laser slotted and reach 0.2mm, but high cost, and be not suitable for the suction filtration of underground water and the process of agricultural water), thus can not be used for the stratum that gravel granularity central diameter is less than 0.15mm.
Three, summary of the invention:
The object of the invention is, for the needs in the deficiencies in the prior art and market, propose a kind of inside and outside infiltration filter pipe and preparation method, especially propose a kind of cost low, in source, rainwater is oozed, stagnant, the filter pipe that stores function and combining road and place construction are seeped water inside and outside using.There is the slot comparatively mated, lower preparation cost; To the soakaway trench of the suction filtration works very well of the underground water of high shale content, cohesive soil, Extra-fine sand.
Technical solution of the present invention is: a kind of inside and outside infiltration filter pipe, comprise the water pipe of Polymer materialspreparation, the axis of water pipe and the tube wall of longitudinal direction and length direction are evenly cracked, and seam width is 0.7-3.5mm, the two ends of water pipe are interior male thread or flange ring structure, and the length of seam is 20-150cm; Filter screen is provided with coated outside the slot of water pipe; Filter screen or add gravel material can according to geological condition and straight-through situation.
Further, the area of slot is the 2-13% of tube-surface area.
Further, uniform parallel slot in the axis of water pipe and the tube wall of length direction, and be dislocatedly distributed to intersect.Filter screen is 50-80 object stainless steel gauze wire cloth or plastic silk screen.
Further, on water pipe, hoop has some groups of twice ring-type fixed strips, and wherein coated filter screen is fixed between twice fixed strip, and the distance between twice fixed strip is 10-60cm.
Further, the area of slot is especially the 5-9% of tube-surface area.
The invention has the beneficial effects as follows: water pipe even level of the present invention is laid on bottom, stratum 50-150cm, is the position that irrigation consideration also can be more shallow, the diameter of inside and outside infiltration filter pipe is 5-60cm all size, filter screen can be provided with coated outside the slot of water pipe, pipe is outer can wrap up sandstone material on a small quantity, and road surface all adopts variously can bear the road surface of pressure or various material.Reach run into when having rainfall can absorb on the spot or nearby, save, permeate, the function of purifying rainwater, inside and outside infiltration filter pipe has the function containing water retaining, and during arid, underground water is by being evenly discarded to ground floor by water pump lifting to water in filter pipe imbibition to pipe.Because of connect interior male thread or flange ring structure be connect between water pipe when sealing uses with.Adopt the high efficiency method of machine cuts after extruded pipe of the present invention, processing cost is low.
Four, accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Fig. 2 is structural representation of the present invention;
Fig. 3 a, 3b are two circular tube circumference component cloth cutter distribution schematic diagrams.
In figure: water pipe 1, screw thread or flange 4, slot 2, filter screen 3, flange 4, cutter 5.
Five, detailed description of the invention:
1 the invention will be further described by reference to the accompanying drawings:
The present invention from inside to outside successively by water pipe 1, slot 2, filter screen 3, flange 4, form.Comprise plumbing solid wall pipe and the bellows water pipe of Polymer materialspreparation, in the axis of water pipe and the tube wall of length direction, longitudinal axis is to even slot, and seam width is 0.7-3.5mm, and the two ends of water pipe are flange ring structure, and the length of seam is 20-150cm; Filter screen is provided with and gravel material is coated outside the slot of water pipe.Tubing comprises various solid wall pipes, the bellows of Polymer materialspreparation, even slot in the axis of water pipe and the tube wall of length direction, seam width is that 0.7-3.5mm, 1.5-2mm are especially common, adopt the cutter of same widths to carry out longitudinal direction and cutting, longitudinal line of cut is evenly distributed on circumferencial direction.The two ends of water pipe connect for interior male thread or flange ring structure.The total length of the seam of every root water pipe is 20-150cm; Can be provided with filter screen outside the slot of water pipe coated, on water pipe, hoop has the two-layer ring-type fixed strip of minimum twice, and wherein coated filter screen is fixed between two-layer fixed strip; Filter screen can be 50-80 object stainless steel gauze wire cloth or plastic silk screen.
