Wide and flexible permeable pipe

Description :

　　Soft permeable pipe is a new type of pipe material with the function of reverse filtration (drainage) of water. It overcomes many drawbacks of drainage pipes due to its unique design principles and excellent performance of constituent materials. It has strong drainage and seepage effects, utilizing the "capillary" phenomenon and "siphon" principle to collect water, permeate and drain in one go. It has the ability to withstand pressure, permeability and filtration to meet engineering design requirements. Not afraid of geological and geographical temperature changes that may cause fractures, and can achieve the effect of discharging clean water without causing secondary pollution to the environment, it belongs to a new type of environmentally friendly product. It is easy to construct, has no joints, and has no special requirements for geology or terrain. It can be used freely in any place where concealed drainage is needed. Soft permeable pipes are widely used by design and construction units due to their excellent quality, perfect performance, and low cost.

　　(1) Soft permeable pipes are treated with high carbon steel wire phosphorus rust prevention and covered with PVC to prevent acid and alkali corrosion. The unique steel wire spiral skeleton ensures that the pipe wall appears flat and can withstand external pressure

　　(2) The non-woven filter layer ensures effective filtration and prevents sediment from entering the tube.

　　(3) High strength polyester fiber. Jingwei adopts high-strength polyester fiber PVC coating. The weft uses special fibers to form sufficient tensile strength

　　Performance testing of soft permeable pipes: The tensile strength and permeability of the newly reinforced fiber spring permeable blind pipe were sampled and tested by the authorized institution Nanjing Institute of Water Resources in China. The results showed that it can withstand sufficient tension during geological sliding and has excellent all-round water permeability and permeability performance.

　　Soft permeable pipe acid and alkali resistance test: The blind pipe adopts high-strength polyester fiber and steel wire wrapped PVC, which has strong acid and alkali resistance and has a protective effect on organic and inorganic chemicals in water quality and soil.

　　(1) Pressure resistant flatness ratio, the blind pipe adopts a spiral reinforcement structure of high-strength spring steel wire, which evenly distributes the external pressure load around the pipe.

　　(2) Restoration performance test: Blind tubes should be compressed by 70% and compressed 50 times during the test, and the restoration should be greater than 90% Soft permeable pipes are supported by rust proof spring coils to form a high pressure resistant soft structure. The non-woven lining is filtered to prevent mud, sand, and impurities from entering the pipe, thus achieving the effect of clean water seepage. The outer layer of polypropylene filament coating has excellent water absorption and can quickly collect excess water from the soil. The covering layer of the rubber reinforcement wall tube and the spring steel ring tube body become an organic whole, with excellent all-round permeability function, which can smoothly penetrate into the tube, while mud and sand impurities are blocked outside the tube, thus achieving the goal of permeability, filtration, and drainage in one go.

　　Connection method: Based on the principle of reliability and convenience

　　Reinforced soft permeable pipe, lined with high-strength spring hard steel wire, treated with phosphoric acid waterproofing, and covered with P.V.C (resistance heating method) on the outside. Filter layer: non-woven fabric filter layer; Permeable and covering materials: High strength nylon yarn is used for warp yarn, and special fibers are used for weft yarn. Pulling Material: Special Strong P.V.C Pulling Agent. Soft permeable pipe is a drainage pipe made of advanced equipment processed by wrapping anti-corrosion steel wire with geotextile and polyester fiber.

　　Application and Function of Flexible Permeable Pipe and Elastic Permeable Pipe

　　In practical engineering applications, considering the dual relationship between drainage and filtration based on engineering conditions and design requirements can fully reflect the unique role of permeable conduits.

　　Intercept and divert rainwater seepage, eliminate the self weight squeezing water of dams, protective slopes and other engineering projects, and the water inside the foundation to increase the stability of the project.

　　In areas with high precipitation, waterproof embankments, protective slopes, and other engineering projects are affected by the impact and infiltration of flowing water inside the embankment (slope), as well as the surface precipitation of the embankment (slope), resulting in a decrease in the bearing capacity of the soil inside the embankment (slope) and the adhesion between the soils. The self weight of the embankment (slope) compresses the water and the water inside the foundation gradually increases. After a long period of accumulation, large pores will be formed along a certain direction inside the embankment (slope), which gradually increase with the pore size and eventually cause collapse and collapse of the embankment, which is commonly known as the phenomenon of pipe surge. The use of non-woven artificial water infiltration pipes will completely solve this problem.

　　Under the significant pressure of the soil layer, the self weight inside the embankment (slope) and the water inside the foundation enter the seepage conduit and are guided away. This reduces the water pressure in the voids inside the embankment (slope), which can maintain the inherent structure of the soil for a long time and increase the stability of the embankment (slope). flexible perforated pipe
