Abstract

The utility model relates to a flexible pipe. The pipe wall of the flexible pipe is divided into three layers. A spiral spring skeleton, nonwoven fabric which is coated on a spring pipe body, and synthetic fiber which is coated on the nonwoven fabric are arranged from an inner wall to an outer wall in sequence. Each layer is bonded. After the pipe of the utility model is buried in the ground, redundant water in a soil layer penetrates into the pipe through the pipe wall and is discharged, and mud, sand and sundries are blocked out of the pipe. The utility model and effectively eliminates the redundant water, and can also avoid soil and water loss. The utility model is especially suitable for the water discharging of soil layers in occasions, such as a retaining wall, a playground, a golf course, a park, a tunnel, etc.

Description

Water penetrative flexible pipe

The utility model relates to a kind of Water penetrative flexible pipe that is used for the stratum draining, and unnecessary water is that tube wall by this water pipe penetrates in the pipe and discharges in the stratum.

Along with development and national economy, quicken hillside development and use imperative, on hillside no matter be build a house, build a railway, highway or tunnel etc. all need to build at the soil layer section and build retaining wall, to prevent high-order native stone collapse, make soil erosion.Yet rainy season is interim, and often heavy rain causes disaster, and because of high-order stratum impeded drainage can cause excess surface water, even causes the landslide of retaining wall large tracts of land, makes traffic paralysis, and in the course of time, high-order water and soil runs off in a large number, and ground is loosening, and its consequence is hardly imaginable.As the also impeded drainage and cause excess surface water behind the Chang Yinyu of greenery patches of having a rest such as sports ground, football field, golf course and park, place mire, humidity are difficult to normal use in addition.For getting rid of the formation water of above-mentioned various occasions, and avoid earth flow to lose, once had and to adopt honeycombed cement pipe or porous PVC pipe abroad, this antipriming pipe is embedded in the stratum, the unnecessary water in stratum is discharged in the aperture inflow pipe of tube wall, and native stone is retained in the stratum.Yet owing to be rigid pipe, the tube wall punching has reduced crushing resistance, damage easily after the backfill of often constructing, and aperture displacement deficiency is also easily stopped up by silt, makes impeded drainage.

The purpose of this utility model provides a kind of being convenient to and buries underground, the soft gutter of cracky not, and it can soil layer water is discharged, and silt particle avoid running off by filtration, the osmosis of tube wall.

Tube wall of the present utility model is a three layer construction, is followed successively by spiral spring frame by inwall to outer wall, is coated on adhesive-bonded fabric on the spring body, is coated on the synthetic fibers on the adhesive-bonded fabric, and is bonding between each layer.Bonding agent between each layer is a PVC glue.

Fibrage and non-woven cloth layer are born and are filtered and the infiltration function in the utility model tube wall, and outermost fibrage is crossed filter sand mud, and the non-woven cloth layer of being close to the spring skeleton filters tiny mud and organic matter.Spring skeleton system adopts high-intensity spiral wire to make, and can bear distortion and resistance to compression.With the utility model pipe be embedded in underground after, unnecessary water in the soil layer infiltrates in the pipe by tube wall discharges, and silt particle and foreign material are blocked in outside the pipe, both got rid of unnecessary water effectively, can avoid soil erosion again, be specially adapted to the soil layer draining of occasions such as retaining wall, sports ground, golf course, park, tunnel.

The utility model is described in further detail below in conjunction with accompanying drawing.

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

As shown in Figure 1, coil spring 1 is the skeleton of tube wall, covers non-woven cloth layer 2 on spring 1, covers terylene fiber 3 on the adhesive-bonded fabric 2 again, forms three layers of mutual bonding tube wall.During the actual use of the utility model, can the multistage straight tube be connected into T shape according to landform, level and oblique 45 ° of uses such as shape combination, effect is better.

Claims

1, a kind of water tube hose that connects is characterized in that tube wall is a three layer construction, is followed successively by spiral spring frame, is coated on adhesive-bonded fabric on the spring body, is coated on the synthetic fibers on the adhesive-bonded fabric to outer wall by inwall, and is bonding between each layer.

2, Water penetrative flexible pipe according to claim 1 is characterized in that the bonding agent between each layer is a PVC glue.
