referring to fig. 11, the plastic blind pipe is made of polypropylene through extrusion and random fusing. The defects of the method are poor pressure bearing capacity and brittle fracture. The flexibility is low, so that the device is not suitable for being used in parts with complicated geological structures. The cold resistance is extremely poor, and the cold-resistant coating can not be used in cold regions with high latitudes, such as northeast and northwest of China. The water permeability is limited and is not suitable for geotechnical engineering in water-rich areas.
Referring to fig. 12, the perforated corrugated pipe is a tubular permeable pipe perforated on the wall of the formed corrugated pipe according to a certain rule. The defects of the method are that the number of the permeable holes is limited, the permeable area is small, the permeable rate is low, and the method is not suitable for geotechnical engineering in regions with rich water. The mechanical property is poor, the compressive capacity is low, the mechanical property of the corrugated pipe is destroyed by secondary mechanical punching of the formed corrugated pipe, and the plastic notch effect is easy to form. The application range is narrow, and the device is not suitable for parts with high requirements on the bearing capacity of the pipe.

The corrosion is easy, the coating is easy to break, the steel wire is easy to corrode after being exposed in soil for a long time, the damage of the pipe is caused, and the seepage and drainage failure is generated, so that the basic requirements on seepage and drainage in various projects can not be met.

In other words, the water guide holes or water guide seams of the tubular members are overlapped and interwoven in a three-dimensional way through the plurality of tubular members which are overlapped in a three-dimensional way, so that the reticular pipe wall 4 of the water seepage pipe is formed.
Referring to fig. 1, 5 and 6, the tubular member is formed of more than 1 helical rib 1.
Further, the tubular member is constructed by 2 to 200 spiral ribs 1. The gaps between the spiral ribs 1 form water guide holes or water guide seams.

The long columnar support ribs 5 are uniformly distributed on the middle upper part of the inner surface of the tubular component, and play a role in strengthening the structural strength of the tubular component, and simultaneously play a role in enabling water near the outer surface of the tubular component to permeate into a cavity of the seepage and drainage pipe through the water guide holes or the water guide seams and then to be guided and drained by the tubular support ribs 5 with the ports not closed in a loop.
Preferably, the plastic net wall type seepage and drainage pipe is composed of more than 2 pipe-shaped structural members, and more than 1 supporting rib 5 is arranged between the inner pipe 2 and the outer pipe 3 and on the inner wall of the inner pipe 2 or the outer wall of the outer pipe 3.

The reinforcing ribs 6 are consistent with the water flow direction of the pipe body, and the water guide and drainage effects are achieved.
The processing technology of the invention is as follows: the material is prepared by using polyethylene PE, polypropylene PP, ethylene-vinyl acetate copolymer EVA, nylon PA or acrylonitrile-butadiene-styrene ABS as raw materials, heating, extruding, rotating, cooling and shaping.
In order to better illustrate the structural features and technical advancement of the present invention, another angle is illustrated as follows: the invention is composed of more than 1 layer of tubular members. The tubular member is composed of 1 or more spiral ribs 1. Water guide holes or water guide seams are formed in gaps among the spiral ribs, and the water guide holes or the water guide seams are overlapped and interwoven to form a net-shaped pipe wall with small water seepage holes distributed on the surface.

In the structure, the spiral ribs 1 on the inner layer and the outer layer support each other, and a powerful guarantee is provided for improving the ring stiffness of the pipe. The net wall type infiltration pipe can control the ring stiffness of the pipe between 3 and 18 by controlling the coil spacing of the spiral ribs 1 and the thickness of the spiral ribs 1. The wall thickness of each layer of structural member of the inner layer is 1-100 mm. The cross section is circular, and the external diameter is between 10 mm and 1000 mm. The cross section is polygonal, and the length of one side of the cross section is 10-1000 mm.
The invented spiral rib 1 forms the water-permeating holes on the wall of said net wall type water-permeating pipe on one hand and forms the supporting skeleton on the other hand. The water seepage holes can collect water seeping from rock soil in 360 degrees in all directions. The meshes on the side wall of the water penetration pipe play a role in collecting water seeped from the surrounding rock soil, and the water collected by the meshes is discharged from the inner cavity of the water penetration pipe, so that the purposes of penetration, drainage and soil stabilization are achieved.
In addition, in order to provide the present invention with better stability and drainage performance, more than 3 support ribs 5 can be added on the inner surface, the middle layer or the lower surface of the present invention, when the cross section of the support rib 5 is circular or rectangular, that is, the support rib 5 is long column, when the cross section of the support rib 5 is arc, that is, the support rib 5 is approximately tile-shaped and semi-circular tube, that is, the support rib 5 is a tube body with an unclosed port. The support ribs 5 are evenly distributed around the inner surface or/and the outer surface of the tubular member.
The preferred scheme is as follows: more than 10 supporting ribs 5 are provided. The supporting ribs 5 with circular or rectangular cross section are parallel to the length of the tubular member, i.e. more than 10 supporting ribs 5 enclose an arc-shaped curved surface. When the seepage drainage pipe is used, the seepage drainage pipe is horizontally arranged, one of more than 10 support ribs 5 with the arc-shaped cross section is positioned at the bottom of the seepage drainage pipe, namely, redundant water in a rock-soil layer infiltrated by meshes is removed through the smooth inner surface of the support rib 5 with the arc-shaped cross section, so that the mechanical strength and the water guiding and draining performance of the seepage drainage pipe are simultaneously improved.
The plastic spiral permeable pipe has the advantages of low investment, low cost, high water permeability, good mechanical property, wide application range and the like. Meets a series of requirements on infiltration, water drainage and soil stabilization, water seepage and drainage durability and the like in geotechnical engineering.
As a novel water permeating material, the plastic net wall type water permeating and draining pipe has excellent mechanical properties such as water permeating and draining properties, excellent compression resistance and impact resistance, high ring stiffness and the like in engineering. The comparison of the water permeability and the raw material cost per unit length M of the plastic blind pipe and the perforated corrugated pipe with the same type is listed below. The total area of the meshes on the unit area in the expanded projected area of the seepage and drainage pipe forms the water permeable area of the invention.
(all compare with the model number of 100mm in outside diameter DN/OD)
It can be seen from the table that the water permeability of the circular plastic net wall type water seepage pipe of the same model is 5.76 times of that of the traditional plastic blind pipe, 11.78 times of that of the traditional product perforated corrugated pipe and 1.06 times of that of the traditional product soft water seepage pipe, and the used raw materials are 62 percent of the plastic blind pipe, 87 percent of the perforated corrugated pipe and 97 percent of that of the soft water seepage pipe.
