[0002] Permeable drainage pipe system is a widely used drainage facility in sponge engineering, which can prevent water accumulation on roads.

[0003] For example, a rainwater permeable drainage pipe with the authorization announcement number "CN205421492U" has a permeable filler layer filled in the pipe cavity groove, and the outside of the pipe cavity groove is natural soil. The inner layer of the drainage pipe is a permeable pipe, and the outer surface of the permeable pipe is a filtering and anti-filtering inner layer. The above-mentioned permeable pipe is a permeable sand pipe with a socket joint, and there is a rubber ring at the plug joint. The utility model solves the problem that the existing rainwater drainage pipes are impermeable and seep, and cannot effectively replenish the water content in the soil and reduce the discharge volume while draining water. However, in the construction of the permeable drainage pipe, it is necessary to lay geotextile in the groove, backfill part of the filter material, install and lay the permeable drainage pipe (including geotextile wrapped around the permeable pipe), backfill part of the filter material on the top of the pipe, arrange and seal the top geotextile, and backfill the top planting soil. The whole process is relatively cumbersome, the construction speed is slow, and the project quality is difficult to guarantee, which reduces the construction efficiency of the permeable drainage pipe and shortens the service life of the permeable drainage pipe. Utility Model Content

[0004] The utility model aims to solve the problem of reducing the construction efficiency of the permeable drainage pipeline and shortening the service life of the permeable drainage pipeline, and proposes an assembled permeable drainage pipeline system.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An assembled permeable drainage pipe system is designed, comprising a connector and an outer pipe, wherein the front of the inner wall of the connector is plugged into the rear of the outer wall of the outer pipe, the outer wall of the outer pipe is processed with multiple openings, the inner wall of the outer pipe is connected to a drainage structure, the inner wall of the outer pipe and the outer wall of the drainage structure are both filled with a filler layer, the inner wall of the outer pipe is fitted with the outer wall of the filler layer, and a reinforcement structure is provided on the surface of the outer pipe.

[0007] Preferably, the drainage structure includes a support ring and a first filter cloth, the outer walls of the multiple support rings are respectively fixedly connected to the inner wall of the outer tube, the inner walls of the multiple support rings are all fixedly connected to the outer wall of the first filter cloth, the inner wall of the first filter cloth is wrapped with an inner tube, and the outer wall of the inner tube is respectively fixedly connected to baffles on the front and rear sides.

[0008] Preferably, the outer wall of the baffle is fixedly connected to the inner wall of the outer tube.

[0009] Preferably, the outer wall of the inner tube is processed with a plurality of openings.

[0010] Preferably, the outer wall of the inner tube and the inner wall of the support ring are both in contact with the inner wall of the packing layer.

[0011] Preferably, the outer wall of the outer tube is wrapped with a second filter cloth.

[0012] The utility model proposes an assembled permeable drainage pipe system, which has the following beneficial effects: a layer of first filter cloth is wrapped around the outer wall of the inner pipe in the drainage structure, and the first filter cloth can shield the soil and ensure that water penetrates into the inner pipe by its own permeable geotextile material, and at the same time, the support ring supports the outer wall of the inner pipe and the inner wall of the outer pipe to ensure that the inner pipe and the outer pipe will not be deformed, thereby changing the layout of the original drainage pipe, improving the construction efficiency of the permeable drainage pipe, and ensuring the service life of the permeable drainage pipe.

[0019] The utility model is further described below in conjunction with the accompanying drawings: Example

[0020] See also Figure 1-5In the present embodiment, an assembled permeable drainage pipe system includes a connector 1 and an outer tube 4. The front of the inner wall of the connector 1 is plugged into the rear of the outer wall of the outer tube 4. After the rear of the inner wall of the connector 1 is plugged into the outer tube 4, it needs to be welded to form a whole. The outer wall of the outer tube 4 is processed with multiple openings. The inner wall of the outer tube 4 is connected to the drainage structure 2. The inner wall of the outer tube 4 and the outer wall of the drainage structure 2 are filled with a filler layer 6. The material of the filler layer 6 is gravel and ceramic particles. The inner wall of the outer tube 4 fits the outer wall of the filler layer 6.

[0021] The drainage structure 2 includes a support ring 201 and a first filter cloth 202. The outer walls of the multiple support rings 201 are respectively fixedly connected to the inner wall of the outer tube 4. The support ring 201 supports the outer tube 4 and the inner tube 203 to prevent deformation. The inner walls of the multiple support rings 201 are all fixedly connected to the outer wall of the first filter cloth 202. The first filter cloth 202 is a permeable geotextile. The inner wall of the first filter cloth 202 is wrapped with the inner tube 203. The outer wall of the inner tube 203 is fixedly connected with baffles 204 on both sides. The outer wall of the baffle 204 is processed with multiple openings to shield the packing layer 6 while allowing water to pass through.

[0022] By wrapping a layer of first filter cloth 202 around the outer wall of the inner tube 203 in the drainage structure 2, the first filter cloth 202 can block the soil and ensure that water penetrates into the inner tube 203 through its own permeable geotextile material. At the same time, the support ring 201 supports the outer wall of the inner tube 203 and the inner wall of the outer tube 4 to ensure that the inner tube 203 and the outer tube 4 will not be deformed, thereby changing the layout of the original drainage pipe, improving the construction efficiency of the permeable drainage pipe, and ensuring the service life of the permeable drainage pipe.

[0023] The outer wall of the baffle 204 is fixedly connected to the inner wall of the outer tube 4. The outer wall of the inner tube 203 is processed with multiple openings. The openings on the outer wall of the inner tube 203 are to ensure the normal passage of water. The outer wall of the inner tube 203 and the inner wall of the support ring 201 are both in contact with the inner wall of the packing layer 6. The outer wall of the outer tube 4 is wrapped with a second filter cloth 5, and the material of the second filter cloth 5 is a permeable geotextile.

[0024] Working principle:

[0025] When the pipe is used, a layer of first filter cloth 202 is wrapped around the outer wall of the inner pipe 203. The first filter cloth 202 can block the soil and ensure that water penetrates into the inner pipe 203 through its own permeable geotextile material. At the same time, the support ring 201 supports the outer wall of the inner pipe 203 and the inner wall of the outer pipe 4 to ensure that the inner pipe 203 and the outer pipe 4 will not be deformed, thereby changing the layout of the original drainage pipe. At the same time, the interlayer between the two pipes is filled with a filler layer 6. The filler layer 6 can block sand and soil through its own gravel and expanded clay material. At the same time, the baffles 204 on the front and back sides of the inner wall of the outer pipe 4 can block the filler layer 6 to prevent the filler layer 6 from loosening. When the two drainage pipes are connected, the front and back sides of the interior of the connector 1 are respectively plugged into the outer wall ends of the two outer pipes 4, and one end is welded and fixed to form a whole. Example

[0026] See also Figure 1-5 : In this embodiment, an assembled permeable drainage pipe system also includes a reinforcement structure 3, which includes a bent plate 301 and a circular mouth 302. The inner side of the bent plate 301 is fixedly connected to the rear of the outer wall of the outer tube 4. The inner wall of the bent plate 301 is processed with a circular mouth 302. The inner wall of the circular mouth 302 is threadedly connected with a bolt 303, and the inner side of the bolt 303 is tightly pressed against the outer wall of the connecting head 1.

[0027] Working principle:

[0028] After the front and rear sides of the inner wall of the connector 1 are respectively plugged into the outer wall of the outer tube 4, the bolt 303 is threaded through the round opening 302 and rotated inward, so that the inner side of the bolt 303 is pressed against the front of the outer wall of the connector 1, so that the connector 1 can be disassembled and assembled while ensuring stability.

[0029] Although the present invention has been shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
