Description

Technical Field

[0001] The utility model relates to the technical field of underground engineering drainage, in particular to a DG drainage blind pipe. Background Art

[0002] A drainage blind pipe refers to a drainage system component that does not lead to the outside. It is usually installed at the bottom of the drainage pipe, which is equivalent to a water stop pit or a deceleration pit. The DG drainage blind pipe is a type of drainage blind pipe. It has the advantages of high surface water permeability, internal water permeability, pressure resistance, adaptability, long life, light weight and easy installation. Therefore, it is widely used in roadbed and shoulder reinforcement drainage of roads and railways, and drainage work in tunnels and subway underground passages.

[0003] After searching, the existing patent (Announcement No.: CN220564887U) discloses a lawn drainage blind seepage pipe, including a main body, a filtering mechanism and a blind pipe mechanism, wherein the filtering mechanism is located inside the main body, and the blind pipe mechanism is located inside the main body. The main body includes a water storage layer 1, a coarse filtering layer 1, a lawn layer 1, a bearing layer 1, a buffer rubber layer 1, a protective shell 1, a connecting pipe 1, a sealing groove 1 and a water inlet 1, wherein the coarse filtering layer 1 is fixedly mounted on the upper end of the water storage layer 1, the lawn layer 1 is fixedly mounted on the upper end of the coarse filtering layer 1, and the bearing layer 1 is fixedly mounted on the lower end of the water storage layer 1. The lawn drainage blind seepage pipe improves the filtering and protection capabilities of the drainage blind seepage pipe through the improvement of the main body. In the actual use of the drainage blind seepage pipe, the accumulated water above the lawn can be quickly infiltrated and filtered to the lower drainage blind seepage pipe as needed, thereby improving the working effect of the lawn drainage blind seepage pipe.

[0004] However, in the above scheme, its pressure-resistant drainage effect is poor. In actual use, the drainage blind pipe itself will be subjected to greater pressure, which may easily cause excessive local deformation or even damage. During installation, the surface is easily punctured by external force, resulting in inconvenience in subsequent use.

[0005] In view of this, the utility model proposes a DG drainage blind pipe. Utility Model Content

[0006] The utility model provides a DG drainage blind pipe, which solves the problem of poor pressure-resistant drainage effect in the related technology.

[0007] The technical solution of the utility model is as follows: a DG drainage blind pipe, comprising a blind pipe body, the surface of the blind pipe body is sleeved with a filter cloth, the inner wall of the blind pipe body is fixedly connected with a nano-anti-fouling layer, the surface of the blind pipe body is provided with seepage holes extending to the nano-anti-fouling layer at equal angles, and the inner wall of the seepage hole is coated with an anti-crystallization layer.

[0008] Preferably, elastic rings are fixedly connected to the surface of the blind tube body at equal intervals, and the cross-section of the elastic rings is in an O-shape.

[0009] Preferably, the filter cloth is made of a water-permeable material, and the cross-section of the filter cloth is O-shaped.

[0010] Preferably, water diversion grooves are provided on the surface of the blind pipe body between the elastic rings, and the water diversion grooves are distributed on the surface of the blind pipe body at equal intervals.

[0011] Preferably, reinforcement grooves are provided on the surface of the blind tube body, and the reinforcement grooves are symmetrically distributed about the vertical center axis of the blind tube body.

[0012] Preferably, the cross-section of the water seepage holes is in the shape of strip holes, and the water seepage holes are distributed on the surface of the blind pipe body at equal intervals and at equal angles.

[0013] The working principle and beneficial effects of the utility model are:

[0014] The utility model provides an elastic ring, a filter cloth, a water diversion groove, a nano-fouling resistant layer and an anti-crystallization layer, and utilizes the elastic ring to improve the pressure resistance and protection of the outer surface of the blind pipe body, avoids deformation and damage of the blind pipe body caused by external forces, and prolongs its service life. The filter cloth can prevent underground sharp objects from puncturing the blind pipe body, and protect its surface. At the same time, it can reduce the blockage of the blind pipe body caused by the entry of large particles of external impurities. The nano-fouling resistant layer can make the inner wall of the blind pipe body smooth, and further reduce the possibility of impurities accumulating on its inner wall to cause poor drainage. The water diversion groove is used to facilitate the accumulation of rainwater on the outer surface of the blind pipe body, and then flow from the seepage hole to the inside of the blind pipe body, thereby improving the flow rate of rainwater and facilitating the smoothness of drainage, thereby improving the pressure resistance and drainage effect of the blind pipe body itself, and facilitating its normal drainage use.
