Description

Technical Field

[0001] This invention belongs to the field of permeable pipe technology, and in particular relates to a flexible permeable pipe connection structure and construction method. Background Technology

[0002] Flexible permeable pipes are a new type of pipe material with reverse filtration and drainage functions. Utilizing capillary action and the siphon principle, they integrate water absorption, permeability, and drainage, possessing pressure resistance, permeability, and reverse filtration properties. They are widely used in drainage systems in civil engineering, roadbeds, tunnels, water conservancy dams, and sports stadiums. In existing technologies, when multiple flexible permeable pipes need to be connected together, tees or crosses are typically used. The flexible permeable pipe is directly fitted onto the outside of the tee or cross and secured with adhesive tape. However, because the flexible permeable pipe is exposed to water for extended periods, the adhesive tape loses its stickiness upon contact with water, leading to insecure connections between the flexible permeable pipe and the tee or cross, or even detachment, causing the drainage system to malfunction. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides a flexible permeable pipe connection structure and construction method, which realizes a reliable and tight connection between the flexible permeable pipe and the multi-port fitting, and is suitable for long-term use.

[0004] The technical solution adopted in this invention is: a flexible permeable pipe connection structure, including a flexible permeable pipe, a multi-port fitting and a friction clamp; one end of the friction clamp is inserted into the flexible permeable pipe and tied to the spiral steel wire of the flexible permeable pipe; the other end is inserted into the multi-port fitting.

[0005] Furthermore, the friction clamp includes a tube wall and a base, the base being disposed at one end of the tube wall along its axial direction, and a through-flow hole being provided in the middle of the two; a hollow interlayer is provided at one end of the tube wall near the base, the hollow interlayer being disposed circumferentially along the tube wall; the base is provided with at least two connecting holes, the connecting holes communicating with the hollow interlayer for threading the spiral steel wire.

[0006] Furthermore, one of the spiral steel wires passes through one of the connecting holes, wraps around the hollow sandwich layer circumferentially, and then passes through another connecting hole to be tied and connected to another spiral steel wire.

[0007] Furthermore, the friction clip includes a first clip and a second clip. The first clip includes an outer ring wall, and the second clip includes an inner ring wall and the base. A columnar groove is formed in the middle of one end of the outer ring wall. The inner ring wall is connected to the base and has an annular groove along its circumference. The end of the inner ring wall away from the base is inserted into the columnar groove to form the tube wall and the hollow interlayer.

[0008] Furthermore, the base is provided with an outwardly flared flange, and the outer ring wall abuts against the outwardly flared flange.

[0009] Furthermore, the outer edge of the outwardly expanding flange is interference-fitted with the inner wall of the flexible permeable pipe.

[0010] Furthermore, the multi-port fitting includes multiple ports, each port having a slot, and the outer wall of the outer ring wall is interference-fitted with the inner wall of the slot.

[0011] Furthermore, the friction clip extends into the flexible permeable pipe to a set depth, and the flexible permeable pipe overlaps with the multi-port fitting, with tape wrapped around the outside of the overlap.

[0012] Furthermore, both the first buckle and the second buckle are thermoplastic molded.

[0013] The construction method for the flexible permeable pipe connection structure described above includes the following steps:

[0014] Remove the layered structure on the outside of the flexible permeable pipe by a set length to expose the spiral steel wire;

[0015] Insert the spiral steel wire into one of the connection holes of the base, wrap it around the hollow interlayer once, and then pass it out through another connection hole to tie it to another spiral steel wire.

[0016] Connect the outer ring wall and the inner ring wall;

[0017] Connect the outer ring wall to the multi-port fitting;

[0018] Insert the second clip into the inside of the flexible permeable pipe;

[0019] Restore the layered structure and wrap tape around the overlap between the layered structure and the multi-port fitting.

[0020] The advantages and positive effects of this invention are:

[0021] (1) By designing friction clips, the spiral steel wire of the flexible permeable pipe is tied to the friction clips, making full use of the original structure of the flexible permeable pipe and realizing a stable connection between the two. At the same time, the two ends of the friction clips are inserted into the flexible permeable pipe and the multi-way fitting respectively. By utilizing the friction between the insertion surfaces, a reliable and tight connection between the friction clips and the multi-way fitting and the flexible permeable pipe is realized. It will not be affected by the water environment, is suitable for long-term use, and ensures the normal operation of the drainage system.

[0022] (2) The structure is simple, the installation is convenient, and the connection quality of the flexible permeable pipe and the multi-way hose is easy to control. Attached Figure Description

[0029] The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0030] This invention proposes a flexible permeable pipe connection structure and construction method to solve the problem in the prior art where the connection between the flexible permeable pipe and the multi-way fitting is not firm or falls off due to the decrease in the viscosity of the tape in rainwater when connecting the flexible permeable pipe and the multi-way fitting. This application, by setting friction clips, provides a stable and firm connection between the flexible permeable pipe and the multi-way fitting, which is not affected by the water environment, ensuring the connection quality of the two in the water environment for a long time, thereby ensuring the construction quality of the drainage project.

[0031] like Figure 1 As shown, this embodiment of the invention proposes a flexible permeable pipe connection structure, including a flexible permeable pipe 1, a multi-port fitting 2, and a friction clamp 3; one end of the friction clamp 3 is inserted into the flexible permeable pipe 1 and tied to the spiral steel wire 11 of the flexible permeable pipe 1; the other end is inserted into the multi-port fitting 2.

[0032] The flexible permeable pipe 1 can be any type of flexible permeable pipe 1 in the prior art, and there are no restrictions here. In general, the flexible permeable pipe 1 includes a spiral steel wire 11 and a layered structure such as a filter layer and a permeable layer arranged sequentially on the outside of the spiral steel wire 11. The spiral steel wire 11 is the supporting skeleton of the layered structure, so that the flexible permeable pipe 1 forms a tubular structure.

[0033] The multi-way fitting 2 can be a tee connector, a cross connector, or other connectors used to connect multiple pipes, and there are no restrictions here.

[0034] This application binds the spiral steel wire 11 to the friction clip 3, making full use of the original structure of the flexible permeable pipe 1 to achieve a stable connection between the two. At the same time, the two ends of the friction clip 3 are respectively inserted into the flexible permeable pipe 1 and the multi-way pipe fitting 2 at the set insertion depth, so that they form a tight contact insertion surface. Through the friction between the insertion surfaces, a reliable and tight connection between the friction clip 3 and the multi-way pipe fitting 2 is achieved, and a tight connection between the flexible permeable pipe 1 and the friction clip 3 is achieved, forming a connected water passage. Through the above technical solution, a stable and reliable connection structure is formed between the multi-way pipe fitting 2, the friction clip 3 and the flexible permeable pipe 1, ensuring the connection stability and tightness of the three. Moreover, compared with the tape connection in the prior art, this connection structure is not affected by the water environment, is suitable for long-term use, and ensures the normal operation of the drainage system.

[0035] Furthermore, in the embodiments of this application, such as Figure 2 As shown, the friction clip 3 includes a tube wall 31 and a base 343. The base 343 is disposed at one end of the tube wall 31 in the axial direction, and a through flow hole 333 is provided in the middle of the two. A hollow interlayer 32 is provided at one end of the tube wall 31 near the base 343. The hollow interlayer 32 is arranged circumferentially along the tube wall 31. The base 343 is provided with at least two connecting holes 344, which communicate with the hollow interlayer 32 for threading a spiral steel wire 11. In other words, the friction clip 3 is a tubular structure with open ends to form a flow hole 333 that allows water to flow through. Along the axial direction of the flow hole 333, the friction clip 3 includes a pipe wall 31 and a base 343. By setting a hollow interlayer 32 and a connecting hole 344, the spiral steel wire 11 of the flexible elastic permeable pipe 1 can enter the interior of the friction clip 3 and then pass through the connecting hole 344 to exit the friction clip 3 for binding connection, so that the friction clip 3 and the flexible elastic permeable pipe 1 are stably connected together.

[0036] In the above embodiment, the flexible permeable pipe 1 has multiple spiral steel wires 11. During binding connection, one spiral steel wire 11 passes through a connecting hole 344, wraps around the hollow interlayer 32 circumferentially, and then exits through another connecting hole 344, where it is bound to another spiral steel wire 11 of the flexible permeable pipe 1. Because the spiral steel wire 11 has a spiral structure, the hollow interlayer 32 allows for easy wrapping of the spiral steel wire 11 around the circumference of the hollow interlayer 32 before it exits through another connecting hole 344. This process does not require bending the spiral steel wire 11, making the operation simple and quick. Simultaneously, it ensures that the spiral steel wire 11 has a certain length inside the friction clip 3, evenly transmitting the tension to the pipe wall 31 and the base 343 when under tension, making it less prone to detachment and ensuring a stable connection. Preferably, the two connecting holes 344 are positioned close together, allowing the spiral steel wire 11 to wrap around the hollow interlayer 32 nearly once before exiting, further facilitating operation and improving connection stability.

[0037] In some other embodiments of this application, multiple connection holes 344 can also be provided, through which multiple spiral steel wires 11 are inserted into and out of the friction clip 3 and tied together with the multiple spiral steel wires 11, which can further enhance the connection stability between the flexible permeable pipe 1 and the friction clip 3.

[0038] Preferably, in another embodiment of this application, such as Figure 3 , Figure 4 As shown, the friction clip 3 includes a first clip 33 and a second clip 34. The first clip 33 includes an outer ring wall 331, and the second clip 34 includes an inner ring wall 341 and a base 343. A columnar groove is formed in the middle of one end of the outer ring wall 331. The inner ring wall 341 is connected to the base 343 and has an annular groove 342 formed along its circumference. The end of the inner ring wall 341 away from the base 343 is inserted into the columnar groove 332 to form a tube wall 31 and a hollow interlayer 32. Specifically, one end of the columnar groove 332 is provided with a flow hole 333, and the other end is provided with a columnar groove 332, which are connected. The diameter of the columnar groove 332 is larger than the diameter of the flow hole 333, so that the inner side of the outer ring wall 331 forms a stepped structure. The diameter of the columnar groove 332 is adapted to the outer diameter of the inner ring wall 341. When the inner ring wall 341 is inserted into the columnar groove 332, the end of the inner ring wall 341 away from the base 343 abuts against the stepped structure. The outer wall of the inner ring wall 341 is tightly connected to the inner wall of the columnar groove 332. The flow hole 333 of the inner ring wall 341 is connected with the flow hole 333 of the outer ring wall 331 to form a complete and continuous flow hole 333. By setting a separable first buckle 33 and a second buckle 34, it is easier to make a hollow sandwich 32 and to make it easier to thread the spiral steel wire 11. After the spiral steel wire 11 is tied, the first buckle 33 and the second buckle 34 are connected together.

[0039] Furthermore, the base 343 is provided with an outwardly expanding flange, and the outer ring wall 331 abuts against the outwardly expanding flange. Specifically, the outer diameter of the outwardly expanding flange is larger than the outer diameter of the outer ring wall 331. When the inner ring wall 341 is inserted into the columnar groove 332 of the outer ring wall 331 and abuts against the stepped structure, the outer ring wall 331 just abuts against the outwardly expanding flange. Through this technical solution, the depth of the inner ring wall 341 inserted into the inner ring wall 341 can be conveniently and accurately controlled, ensuring the connection quality between the two.

[0040] Furthermore, based on the above embodiments, the outer edge of the outwardly expanding flange is interference-fitted with the inner wall of the flexible permeable pipe 1. This arrangement increases the friction between the friction clip 3 and the connecting surface of the flexible permeable pipe 1, making the connection more stable and less prone to loosening. The connecting part can withstand greater external loads and resist certain vibrations.

[0041] Furthermore, the multi-port fitting 2 includes multiple ports, each with a slot. The slot is a common structure in existing multi-port fittings 2 and will not be described in detail here. The outer wall of the outer ring wall 331 is interference-fitted with the inner wall of the slot 21. Similarly, by setting the outer ring wall 331 and the slot to an interference fit, the friction between the friction clip 3 and the connecting surface of the multi-port fitting 2 can be increased, making the connection more stable and less prone to loosening.

[0042] The friction clip 3 extends into the flexible permeable pipe 1 to a set depth. The flexible permeable pipe 1 overlaps with the multi-way fitting 2, and tape is wrapped around the outside of the overlap. In a specific embodiment, when connecting the friction clip 3 and the flexible permeable pipe 1, the layered structure on the outside of the spiral steel wire 11 is removed by a set length. This length is set according to the required overlap length between the flexible permeable pipe 1 and the multi-way fitting 2. After the friction clip 3 and the flexible permeable pipe 1 are connected, the friction clip 3 and the multi-way fitting 2 are connected. The removed layered structure is then restored to its original state, so that the layered structure is fitted onto the outside of the multi-way fitting 2, thus achieving the overlap between the flexible permeable pipe 1 and the multi-way fitting 2. Then, tape is wrapped around the outside of the layered structure at the overlap. Through this technical solution, the tape and the friction clip 3 together form a multiple connection structure, further improving the stability of the connection between the flexible permeable pipe 1 and the multi-way fitting 2.

[0043] In this embodiment, both the first clip 33 and the second clip 34 are thermoplastic molded, which simplifies the manufacturing process, increases production efficiency, and improves the precision of the processing dimensions. This enhances the practicality of the friction clip 3 and helps ensure the construction quality of the connection structure of the flexible permeable pipe 1. The first clip 33 and the second clip 34 can be made of ABS or PC material, or other materials with similar properties; no limitation is imposed here.

[0044] The construction method for the above-mentioned flexible permeable pipe connection structure proposed in this application includes the following steps:

[0045] S1. Remove the layered structure on the outside of the flexible permeable pipe 1 by a set length to expose the spiral steel wire 11.

[0046] In this embodiment, the flexible permeable pipe 1 includes a spiral steel wire 11 and a layered structure such as a filter layer and a permeable layer arranged sequentially on the outside of the spiral steel wire 11. The layered structure is generally made of non-woven fabric or other fabrics. At the port of the flexible permeable pipe 1, in order to expose the spiral steel wire 11, the layered structure on the outside of the spiral steel wire 11 needs to be stacked away from the port. Care should be taken to avoid damaging the layered structure during operation.

[0047] S2. Insert the spiral steel wire 11 into one of the connection holes 344 of the base 343, wrap it around the hollow sandwich layer 32 once, and then pass it out through another connection hole 344 to tie it to another spiral steel wire 11.

[0048] In this embodiment, the base 343 is provided with two connection holes 344, which are adjacent to each other; the flexible permeable pipe 1 has multiple spiral steel wires 11; one spiral steel wire 11 is passed through one of the connection holes 344, and after wrapping around the hollow interlayer 32 once, it is passed out from the other connection hole 344 and tied to another spiral steel wire 11 on the flexible permeable pipe 1.

[0049] S3, connecting the outer ring wall 331 and the inner ring wall 341;

[0050] The inner ring wall 341 is inserted into the columnar groove 332 of the outer ring wall 331, so that one end of the outer ring wall 331 abuts against the outwardly expanding flange of the second buckle 34, thereby realizing the connection between the first buckle 33 and the second buckle 34.

[0051] S4. Connect the outer ring wall 331 to the multi-way fitting 2;

[0052] Align the slot of the multi-port fitting 2 with the outer ring wall 331, so that the outer ring wall 331 extends into the depth of the slot.

[0053] S5. Insert the second buckle 34 into the inside of the flexible permeable pipe 1;

[0054] Make the outwardly expanding flange of the second buckle 34 engage with the inner side of the flexible permeable pipe 1, and ensure a secure connection;

[0055] S6. Restore the layered structure and wrap tape around the overlap between the layered structure and the multi-port fitting 2.

[0056] The restored layered structure is fitted onto the outside of the multi-way fitting 2 to form an overlap; tape is wrapped around the overlap to ensure that the layered structure fits tightly against the outside of the multi-way hose.

[0057] The advantages and positive effects of this invention are:

[0058] (1) By designing friction clips, the spiral steel wire of the flexible permeable pipe is tied to the friction clips, making full use of the original structure of the flexible permeable pipe and realizing a stable connection between the two. At the same time, the two ends of the friction clips are inserted into the flexible permeable pipe and the multi-way fitting respectively. By utilizing the friction between the insertion surfaces, a reliable and tight connection between the friction clips and the multi-way fitting and the flexible permeable pipe is realized. It will not be affected by the water environment, is suitable for long-term use, and ensures the normal operation of the drainage system.

[0059] (2) The structure is simple, the installation is convenient, and the connection quality of the flexible permeable pipe and the multi-way hose is easy to control.

[0060] The embodiments of the present invention have been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
