Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water-permeable pipes, in particular to a water-permeable pipe capable of directional drainage. Background Art
[0002] Permeable pipe is a kind of pipe that has the function of filtering water and draining water. Common permeable pipes include blind pipes and soft permeable pipes. It can be used for underground drainage in tunnels, central isolation zones of highways, water conservancy dams and other occasions. Permeable pipes are mostly circular pipes. Existing permeable pipes can filter water in all directions. The water in the soil layer is filtered and then seeps into the permeable pipe, and then is discharged along the inner cavity of the permeable pipe. During the discharge process, water on the path will enter the permeable pipe, and water that has entered the permeable pipe will also leak. This phenomenon has no effect on occasions where there are no requirements for the foundation. However, in occasions such as roads and tunnels, a waterproof layer needs to be laid when building the foundation to prevent water leakage. When the permeable pipe is used to drain the central isolation zone of the highway or the tunnel, it will inevitably pass through the roadbed. The accumulated water seeping into the roadbed will affect the service life.
[0003] The existing solution is to lay pipes in sections: permeable pipes are laid under areas with accumulated water, and impermeable drainage pipes are laid in areas that need waterproofing. This method is cumbersome to operate, and water still seeps into the foundation where the two pipes are connected. Summary of the invention
[0004] The utility model aims at the deficiencies of the prior art and develops a directional drainage permeable pipe, which can independently drain water in the soil layer to a designated area without leakage on the way.
[0005] The technical solution of the utility model to solve the technical problem is: the embodiment of the utility model provides a permeable pipe with directionable drainage, including a support frame and a water filter layer, the support frame is a spiral steel wire, the water filter layer is wrapped around the outside of the support frame, the water filter layer is a cylindrical shape composed of non-woven fabric, and a water-proof layer is also provided at the bottom of the water filter layer, the water-proof layer is fitted with the bottom of the water filter layer, and the water-proof layer is a concave shape composed of a plastic film.
[0006] As an optimization, the waterproof layer is arranged on the inner side or outer side of the bottom of the water filtering layer.
[0007] As an optimization, the rotation path of the support frame is a square spiral, the waterproof layer is U-shaped, and the waterproof layer includes a horizontal bottom surface and two symmetrical side surfaces, and the two side surfaces are perpendicular to the bottom surface.
[0008] As an optimization, the height of the two sides of the waterproof layer accounts for 1 / 3 of the height of the water filtering layer.
[0009] As an optimization, the rotation path of the support frame is a circular spiral, and the waterproof layer is an arc shape.
[0010] As an optimization, the curvature of the waterproof layer is 120 degrees.
[0011] As an optimization, a plurality of counterweight blocks are evenly arranged on the outer side of the bottom of the water filtration layer.
[0012] As an optimization, a plurality of guide blocks are symmetrically arranged on both sides of the bottom of the water filtration layer.
[0013] 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:
[0014] 1. By improving the soft permeable pipe, a plastic film waterproof layer is set at the bottom of the water filter layer. The plastic film waterproof layer is elastic and can be folded and bent with the soft permeable pipe, which is convenient for transportation and pipe laying. The moisture in the soil layer can enter the permeable pipe through the non-woven fabric filter layer and finally fall on the waterproof layer, and then be discharged along the waterproof layer. The moisture will not leak out after entering the permeable pipe. The moisture can enter the permeable pipe through the non-woven fabric filter layer, but cannot spread horizontally along the filter layer and will not penetrate into the foundation. The permeable pipe can independently drain the water in the soil layer to the designated area without leakage on the way.
[0015] 2. Setting the waterproof layer on the inner side of the bottom of the water filter layer can protect the waterproof layer; setting the waterproof layer on the outer side of the bottom of the water filter layer is convenient for processing.
[0016] 3. Water can only enter the permeable pipe through the area where the water filter layer is not covered by the water-blocking layer. The water-passing area of the water-blocking layer must be able to meet the drainage requirements. The support frame is set to be square, and the height of the two sides of the water-blocking layer accounts for 1 / 3 of the height of the water filter layer, or the support frame is circular, and the curvature of the water-blocking layer is 120 degrees, which can meet both the permeability and drainage requirements.
[0017] 4. By arranging a counterweight block on the outside of the bottom of the water filter layer, the bottom of the water pipe can be easily found when laying the water pipe, ensuring that the installation direction of the water pipe is correct.
[0018] 5. By symmetrically arranging a plurality of guide blocks on both sides of the bottom of the water filter layer, when the guide blocks on both sides touch the ground, the bottom surface of the permeable pipe automatically faces downward, which facilitates the correct installation of the permeable pipe.

[0028] In order to clearly illustrate the technical features of the present invention, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.
[0029] Embodiment 1: Figure 1 , Figure 2 The first embodiment of the present utility model is as follows: Figure 1 As shown, a permeable pipe capable of directional drainage includes a support frame 1 and a water filter layer 2. The support frame 1 is a spiral steel wire. The water filter layer 2 is wrapped outside the support frame 1. The water filter layer 2 is a cylindrical shape composed of non-woven fabric. A water-blocking layer 3 is also provided at the bottom of the water filter layer 2. The water-blocking layer 3 is in a concave shape composed of a plastic film. The water-blocking layer 3 is arranged on the inner side of the bottom of the water filter layer 2. The water-blocking layer 3 is arranged on the inner side of the bottom of the water filter layer 2 to protect the water-blocking layer 3 and prevent the water-blocking layer 3 from being punctured during transportation or construction, resulting in water leakage.
[0030] The rotation path of the support frame 1 is a circular spiral, and the waterproof layer 3 is an arc. The arc of the waterproof layer 3 is 120 degrees. Water can only enter the permeable pipe through the area where the water filter layer 2 does not cover the waterproof layer 3. The water flow area of the waterproof layer 3 must be able to meet the drainage requirements. The support frame 1 is set to be circular, and the arc of the waterproof layer 3 is 120 degrees, which can meet both the permeability requirements and the drainage requirements.
[0031] Working principle: By improving the soft permeable pipe, a plastic film waterproof layer 3 is set at the bottom of the water filter layer 2. The plastic film waterproof layer 3 is elastic and can be folded and bent together with the soft permeable pipe, which is convenient for transportation and pipe laying. After installation, the moisture in the soil layer can enter the permeable pipe through the non-woven fabric water filter layer 2, and finally fall on the waterproof layer 3, and then be discharged along the waterproof layer 3. The moisture will not leak out after entering the permeable pipe. The moisture can enter the permeable pipe through the non-woven fabric water filter layer 2, but it cannot spread horizontally along the water filter layer 2 and will not penetrate into the foundation. The permeable pipe can independently drain the water in the soil layer to the designated area without leakage on the way.
[0032] Embodiment 2: Figure 3 , Figure 4 This is the second embodiment of the utility model, which is different from the first embodiment in that the rotation path of the support frame 1 is a square spiral, the waterproof layer 3 is U-shaped, and the waterproof layer 3 includes a horizontal bottom surface and two symmetrical side surfaces, and the two side surfaces are perpendicular to the bottom surface. The height of the two side surfaces of the waterproof layer 3 accounts for 1 / 3 of the height of the water filter layer 2. The support frame 1 is set to be square, and the height of the two side surfaces of the waterproof layer 3 accounts for 1 / 3 of the height of the water filter layer 2, which can meet both the permeability requirements and the drainage requirements.
[0033] Embodiment 3: Figure 5 , Figure 6 This is the third embodiment of the utility model, which is different from the first embodiment in that a plurality of counterweights 4 are evenly arranged on the outside of the bottom of the water filter layer 2. By arranging the counterweights 4 on the outside of the bottom of the water filter layer 2, when laying the water permeable pipe, the bottom of the water permeable pipe can be easily found, ensuring that the installation direction of the water permeable pipe is correct.
[0034] Embodiment 4: Figure 7 , Figure 8 This is the fourth embodiment of the utility model, which is different from the first embodiment in that a plurality of guide blocks 5 are symmetrically arranged on both sides of the bottom of the water filter layer 2. By symmetrically arranging a plurality of guide blocks 5 on both sides of the bottom of the water filter layer 2, when the guide blocks 5 on both sides touch the ground, the bottom surface of the water permeable pipe automatically faces downward, which facilitates the correct installation of the water permeable pipe.
[0035] Although the specific implementation methods of the utility model are described above in conjunction with the accompanying drawings, this does not limit the scope of protection of the utility model. On the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
