Description

A kind of inside and outside infiltration filter pipe

One, technical field

The utility model relates to a kind of infiltration pipe; The water pipe of especially a kind of inside and outside infiltration filter water compatibility.

Two, background technology

The proposition in sponge city is that nature and ecological thinking are produced by the mankind, comprising the theory that the Nature is revered, the construction in sponge city need comprehensive to adopt " ooze, stagnant, store, clean, 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 owing to original natural hydrological characteristics and water ecological environment are caused by city development construction behavior to greatest extent, urban construction is become " cavernous body " of " accumulation naturally, naturally osmotic, natural purification ". Namely city is as sponge, run into can absorb on the spot or nearby when having rainfall, save, permeate, purifying rainwater, recharge of groundwater, regulate water cycle; Have ready conditions when drought and water shortage and the water stored is discharged, and be used.

The construction in sponge city needs to ooze, stagnant, store, clean, use, the engineering technological facilities 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, the source such as stagnant, storage is to rainwater utilization and reduction of discharging is the most important part. In source, rainwater is oozed, stagnant, store must combining road and place construction and use and filter water water pipe.

Existing filter pipe, can also prevent except water inlet is outer the particle of soil or rock around the borehole wall from flowing in well and silt well pipe up, also plays a part to support simultaneously and protects the borehole wall, and the hole that makes to draw water can normally use. The charges that some hard crack, solution crack waterbearing stratum wellbore stability are unloose again, the Shi Buxu that draws water installs filter pipe, and loose hole waterbearing stratum or the basement rock waterbearing stratum of fragmentation, must install applicable filter pipe. Also commonly using cement gravel filter pipe in agricultural supply well, the brick wood borehole wall of people's well has in fact also been the effect of filter water, resource of purifying waste water. Meanwhile, in large-scale country project, e.g., divert water from the south to the north project, Olympic Games diving place-the Water Cube, thing conveying engineering etc., all to be used and high-quality 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 the application of current petroleum industry all also exist certain weak point. Cutting seam sieve tube, due to technology and the reason becoming present aspect, slot width is greater than 0.15mm, and (plasma slot patented technology can reach the most I of 0.15mm laser slotted and reach 0.2mm, but cost is too high, and it is not suitable for the process taking out filter and agricultural water of underground water), thus can not be used for the stratum that gravel granularity central diameter is less than 0.15mm.

Three, practical novel content:

The purpose of this utility model is, for the needs of the deficiencies in the prior art and market, propose a kind of inside and outside infiltration filter pipe, especially propose a kind of cost low, in source, rainwater is oozed, stagnant, store function and combining road and place construction use inside and outside seep water filter pipe. There is the slot relatively mated, lower preparation cost; To the infiltration pipe taking out filter works very well of the underground water of high shale content, cohesive soil, Extra-fine sand.

Technical solutions of the utility model are: 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, seam width is 0.7-3.5mm, the two ends of water pipe are that inside and outside silk is buckled or flange ring structure, and the length of seam is 20-150cm; It is provided with filter screen 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, even 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 woven wire 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 beneficial effects of the utility model are: the even level of the utility model water pipe is laid on bottom, stratum 50-150cm, is the position that irrigation consideration can also 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 various can bear the road surface of pressure or various material. Reach run into can absorb on the spot or nearby when having rainfall, save, permeate, the function of purifying rainwater, inside and outside infiltration filter pipe has the function containing water retaining, during arid underground water by filter pipe imbibition to pipe thus be evenly discarded to ground surface layer by water pump lifting to water. Because of connect inside and outside silk button or flange ring structure be connect between water pipe when sealing uses with. Adopting the high efficiency method of cut mechanically after the utility model extruded pipe, tooling cost is low.

Four, accompanying drawing illustrates:

Fig. 1 is structural representation of the present utility model;

Fig. 2 is structural representation of the present utility model;

Fig. 3 a, 3b are two circular tube circumference component cloth cutter distribution schematic diagrams.

In figure: water pipe 1, silk buckle or flange 4, slot 2, filter screen 3, flange 4, cutter 5.

Five, embodiment:

1 the utility model will be further described by reference to the accompanying drawings:

The utility model from inside to outside successively by water pipe 1, slot 2, filter screen 3, flange 4, form. Comprising plumbing solid wall pipe and the corrugated tube water pipe of Polymer materialspreparation, in the axis of water pipe and the tube wall of length direction, longitudinal axes 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; Be provided with filter screen outside the slot of water pipe and gravel material coated. Tubing comprises various solid wall pipes, the corrugated tube 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, adopting the cutter of same widths to carry out longitudinally and cutting, longitudinal line of cut is evenly distributed on circumferential direction. The two ends of water pipe connect buckles or flange ring structure for inside and outside silk. The total length of the seam of every root water pipe is 20-150cm; Can being provided with filter screen outside the slot of water pipe coated, on water pipe, hoop has minimum twice two layers of ring-type fixed strip, and wherein coated filter screen is fixed between two layers of fixed strip; Filter screen can be 50-80 object stainless steel woven wire or plastic silk screen.
