Description

Technical Field

[0001] The utility model relates to the technical field of soft water-permeable pipes, in particular to a pressure-resistant soft water-permeable pipe. Background Art

[0002] Soft permeable pipe is a kind of pipe with water filtering and drainage functions. It has the advantages of being foldable, easy to transport, bendable, and easy to lay pipes. It can be used for underground drainage in tunnels, central isolation zones of highways, water conservancy dams and other places. The soft permeable pipe includes a support frame and a filter cloth. The support frame is a spiral round steel wire, and the filter cloth is a permeable non-woven fabric. The filter cloth is wrapped outside the support frame. The existing soft permeable pipe is prone to lodging, which affects the smooth progress of drainage operations.

[0003] In the prior art, in order to overcome the problem of easy deformation of soft water-permeable pipes, the utility model patent with authorization announcement number CN215596625U discloses a pressure-resistant soft water-permeable pipe, comprising an outer coil spring steel wire, an inner coil spring steel wire and a filter layer, wherein the filter layer is wrapped on the outer coil spring steel wire; the diameter of the inner coil spring steel wire is smaller than the diameter of the outer coil spring steel wire, the inner coil spring steel wire is located inside the outer coil spring steel wire, and the inner coil spring steel wire is arranged along the axial direction of the outer coil spring steel wire; multiple groups of connecting mechanisms are arranged between the outer coil spring steel wire and the inner coil spring steel wire, the multiple groups of connecting mechanisms are sequentially distributed along the axial direction of the outer coil spring steel wire, and the outer coil spring steel wire is connected to the inner coil spring steel wire through the multiple groups of connecting mechanisms. The overall structural strength and pressure resistance can be improved, and deformation is not easy to occur under the action of external force, thereby ensuring the smooth progress of drainage operations.

[0004] In the process of realizing the utility model, the inventors found that there are at least the following problems in the prior art: 1. The prior art improves the compressive resistance at the expense of the foldability and bending ability of the soft permeable pipe. The folding ability of the improved soft permeable pipe is reduced, and the volume after folding is larger than before, which is inconvenient for transportation; the bending ability is reduced, which is inconvenient for pipe laying; 2. The supporting structure in the prior art adds an inner coil spring steel wire and a connecting mechanism on the basis of the original outer coil spring steel wire, which increases the material cost on the one hand and the processing and manufacturing cost on the other hand, while increasing the product weight and the transportation cost, which is not conducive to market competition. Summary of the invention

[0005] The utility model aims at the deficiencies of the prior art and develops a pressure-resistant soft water-permeable pipe, which solves the problem of the soft water-permeable pipe being easy to fall over without sacrificing the folding performance and bending ability, thereby ensuring the smooth progress of drainage work.

[0006] The technical solution of the utility model to solve the technical problem is: an embodiment of the utility model provides a pressure-resistant soft permeable pipe, including a filter cloth and a support frame, the support frame is a spiral steel wire, the filter cloth is a water-permeable non-woven fabric, the filter cloth is wrapped around the outside of the support frame, and the cross-section of the steel wire of the support frame is any one of an elliptical, triangular, and rectangular shape.

[0007] As an optimization, the cross section of the steel wire of the support frame is square.

[0008] As an optimization, the cross section of the steel wire of the support frame is a rectangle, and the long side of the rectangle fits with the inner surface of the filter cloth.

[0009] As an optimization, the cross section of the steel wire of the support frame is a triangle, and the longest side of the triangle fits with the inner surface of the filter cloth.

[0010] As an optimization, the cross section of the steel wire of the support frame is elliptical, and the short diameter of the ellipse is perpendicular to the filter cloth.

[0011] As an optimization, support cloths are further arranged on both sides of the filter cloth, and the support cloths are horizontally and symmetrically arranged on both sides of the filter cloth.

[0012] As an optimization, the supporting cloth is arranged in the upper middle part of the filter cloth.

[0013] As an optimization, horizontal support bars are further arranged on both sides of the support frame, the support bars are connected to the support frame, and the support bars penetrate the filter cloth.

[0014] As an optimization, partitions are further provided at the openings at both ends of the filter cloth, water-permeable holes are evenly provided on the partitions, and the partitions are connected to the filter cloth.

[0015] The effects provided in the utility model content are only the effects of the embodiments, not all the effects of the utility model. The above technical solution has the following advantages or beneficial effects:

[0016] 1. The cross section of the steel wire of the original support frame is circular, and the circular surface contacts the ground, which has little grip and is prone to lodging. By setting the cross section of the steel wire of the support frame to any one of an ellipse, triangle, or rectangle, the contact surface between the steel wire and the ground becomes a plane or a large elliptical arc surface, which enhances the grip and is not prone to rotation and lodging. The soft permeable pipe changes the shape of the cross section of the steel wire of the support frame, solves the problem of the soft permeable pipe easily lodging without sacrificing the folding performance and bending ability, and ensures the smooth progress of drainage work.

[0017] 2. By setting the long side of the rectangle to fit with the inner surface of the filter cloth, or the longest side of the triangle to fit with the inner surface of the filter cloth, or the short diameter of the ellipse to be perpendicular to the filter cloth, the most stable side of the cross section of the support frame steel wire is fitted with the inner surface of the filter cloth. When in use, the most stable side of the cross section of the support frame steel wire is in contact with the ground, thereby achieving an optimal stability structure.

[0018] 3. By setting support cloth on both sides of the filter cloth, when burying the soft water-permeable pipe, first bury and tamp the bottom of the support cloth, then straighten the soft water-permeable pipe and lay the support cloth on both sides of the filter cloth, and continue to bury to complete the arrangement of the soft water-permeable pipe. The support cloth can offset the pressure on the soft water-permeable pipe and improve the anti-lodging ability. The support cloth is set in the middle and upper part of the filter cloth, and the landfill volume under the support cloth is increased, which can make the structure of the soft water-permeable pipe more stable.

[0019] 4. By setting horizontal support bars on both sides of the support frame, the support bars are kept horizontal when the soft water-permeable pipes are arranged. After the support bars are buried, the support bars are fixed in the soil layer, which can offset the pressure on the soft water-permeable pipes and improve the anti-lodging ability. Compared with the support cloth, there is no need to bury in steps.

[0020] 5. By setting partitions at the openings at both ends of the filter cloth, large soil and rocks can be prevented from entering the soft permeable pipe during the landfill process, affecting drainage. BRIEF DESCRIPTION OF THE DRAWINGS

The support frame 2 is a spiral steel wire, the filter cloth 1 is a water-permeable non-woven fabric, and the filter cloth 1 is wrapped around the outside of the support frame 2. The steel wire cross-section of the support frame 2 is a rectangle, and the long side of the rectangle is in contact with the inner surface of the filter cloth 1.

[0034] Embodiment 2: Figure 3 , Figure 4 This is the second embodiment of the utility model, which differs from the first embodiment in that the cross section of the steel wire of the support frame 2 is a triangle, and the longest side of the triangle is in contact with the inner surface of the filter cloth 1 .

[0035] Embodiment 3: Figure 5 , Figure 6 This is the second embodiment of the utility model, which differs from the first embodiment in that the cross section of the steel wire of the support frame 2 is elliptical, and the short diameter of the ellipse is perpendicular to the filter cloth 1 .

[0036] Design principle: The cross section of the steel wire of the support frame 2 is any one of an ellipse, a triangle, and a rectangle. The cross section of the steel wire of the original support frame 2 is a circle, and the round surface is in contact with the ground, so the grip is very small and it is easy to fall over. By setting the cross section of the steel wire of the support frame 2 to any one of an ellipse, a triangle, and a rectangle, the contact surface between the steel wire and the ground becomes a plane or a large elliptical arc surface, which enhances the grip and is not easy to rotate and fall over. The soft permeable pipe changes the shape of the cross section of the steel wire of the support frame 2, and solves the problem of the soft permeable pipe easily falling over without sacrificing the folding performance and bending ability, thereby ensuring the smooth progress of drainage work.

[0037] By setting the long side of the rectangle to fit with the inner surface of the filter cloth 1, or the longest side of the triangle to fit with the inner surface of the filter cloth 1, or the short diameter of the ellipse to be perpendicular to the filter cloth 1, the most stable side of the cross section of the steel wire of the support frame 2 is fitted with the inner surface of the filter cloth 1. When in use, the most stable side of the cross section of the steel wire of the support frame 2 is in contact with the ground, thereby achieving an optimal stability structure.

[0038] Embodiment 4: Figure 7 , Figure 8This is the fourth embodiment of the utility model, which differs from the first embodiment in that support cloth 11 is further provided on both sides of the filter cloth 1, and the support cloth 11 is horizontally symmetrically provided on both sides of the filter cloth 1. The support cloth 11 is provided in the middle and upper part of the filter cloth 1. By providing support cloth 11 on both sides of the filter cloth 1, when burying the soft water-permeable pipe, first bury and tamp the bottom of the support cloth 11, then straighten the soft water-permeable pipe and lay the support cloth 11 on both sides of the filter cloth 1, and continue to bury to complete the arrangement of the soft water-permeable pipe. The support cloth 11 can offset the pressure on the soft water-permeable pipe and improve the anti-lodging ability. The support cloth 11 is provided in the middle and upper part of the filter cloth 1, and the landfill amount under the support cloth 11 is increased, which can make the structure of the soft water-permeable pipe more stable.

By providing horizontal support bars 21 on both sides of the support frame 2, when the soft water-permeable pipe is arranged, the support bars 21 are kept horizontal, and after the support bars 21 are buried, the support bars 21 are fixed in the soil layer, which can offset the pressure on the soft water-permeable pipe and improve the anti-lodging ability. Compared with the support cloth 11, it is not necessary to bury in steps.
