[0003] The cross-section of the existing composite drainage pipe is usually circular, and it is very easy to deform when the drainage pipe is squeezed, causing the water flow pressure to change, which can easily cause the drainage pipe joint to fall off and the drainage pipe to be damaged, thereby affecting normal drainage.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 4 In order to solve the problem that the cross section of the existing composite drainage pipe is usually circular, and the drainage pipe is very easy to deform when squeezed, causing the water flow pressure to change, which is easy to cause the drainage pipe joint to fall off and the drainage pipe to be damaged, thereby affecting normal drainage, the following preferred technical solutions are provided:

[0022] A pressure-resistant and leak-proof composite drainage pipe comprises a pipe body 1, an outer wall of which is fixedly connected with a pressure-resistant ring 2, a plurality of pressure-resistant rings 2 are provided, and the plurality of pressure-resistant rings 2 are evenly arranged and distributed about the outer wall of the pipe body 1, the pressure-resistant ring 2 is a component made of rubber material, and the shape of the pressure-resistant ring 2 is a circular ring, an inner wall of the pressure-resistant ring 2 is fixedly connected with a first pressure-resistant block 3 and a second pressure-resistant block 4, the first pressure-resistant block 3 and the second pressure-resistant block 4 are symmetrically distributed about the center of the pressure-resistant ring 2, a plurality of first pressure-resistant blocks 3 and the second pressure-resistant blocks 4 are provided, and are evenly distributed around the center of the pressure-resistant ring 2, and the composition structure of the first pressure-resistant block 3 and the second pressure-resistant block 4 is the same.

[0023] The second anti-compression block 4 includes an upper connecting block 41 and a lower connecting block 42 which are respectively fixedly connected to the inner wall of the anti-compression ring 2, an elastic element 43 is fixedly connected between the upper connecting block 41 and the lower connecting block 42, a first connecting piece 44 is fixedly connected to one side of the upper connecting block 41, a second connecting piece 45 is fixedly connected to one side of the lower connecting block 42, an elastic bent rod 46 is fixedly connected between the first connecting piece 44 and the second connecting piece 45, and the elastic bent rod 46 is a component made of beryllium bronze.

[0024] Specifically, when the outer wall of the pipe body 1 is under pressure, the pressure will first act on the anti-pressure ring 2, and the pressure will squeeze and deform the anti-pressure ring 2, driving the upper connecting block 41 and the lower connecting block 42 to move closer to each other, thereby squeezing the elastic element 43, so that the elastic element 43 is in a compressed state, and the first connecting piece 44 and the second connecting piece 45 will also be driven to squeeze the elastic bent rod 46, so that the bending angle of the elastic bent rod 46 is larger. At this time, the elastic reaction force of the elastic element 43 and the elastic bent rod 46, combined with the restorability of the anti-pressure ring 2 itself, will buffer and weaken the pressure, thereby protecting the pipe body 1 and ensuring normal drainage. This solves the problem that the cross-section of the existing composite drainage pipe is usually circular, and it is very easy to deform when the drainage pipe is squeezed, causing changes in the water flow pressure, which can easily cause the drainage pipe joint to fall off and the drainage pipe to be damaged, thereby affecting normal drainage.

[0025] The pipe body 1 includes a substrate layer 11, an anti-corrosion layer 12 is bonded to the outer wall of the substrate layer 11, a water-absorbing layer 13 is bonded to the outer wall on the side of the substrate layer 11 away from the anti-corrosion layer 12, and a waterproof layer 14 is bonded to the outer wall on the side of the water-absorbing layer 13 away from the anti-corrosion layer 12. The water-absorbing layer 13 is a component made of water-absorbing resin material.

[0026] Specifically, the waterproof layer 14 can be used to make the substrate layer 11 waterproof to prevent water from corroding the substrate layer 11. The anti-corrosion layer 12 can alleviate the erosion and slow down the erosion rate, thereby increasing the service life. Since the water-absorbing resin material has high water absorption, the water that breaks through the waterproof layer 14 can be absorbed by the water-absorbing layer 13, thereby further slowing down the erosion rate, and the practicality is good.

[0027] To sum up: when the outer wall of the pipe body 1 is under pressure, the pressure will first act on the anti-pressure ring 2, and the pressure will squeeze and deform the anti-pressure ring 2, driving the upper connecting block 41 and the lower connecting block 42 to move closer to each other, thereby squeezing the elastic element 43, so that the elastic element 43 is in a compressed state, and the first connector 44 and the second connector 45 will also be driven to squeeze the elastic bent rod 46, so that the bending angle of the elastic bent rod 46 is larger. At this time, the elastic reaction force of the elastic element 43 and the elastic bent rod 46, combined with the restorability of the anti-pressure ring 2 itself, will buffer and weaken the pressure, thereby protecting the pipe body 1 and ensuring normal drainage; the waterproof layer 14 can waterproof the substrate layer 11 to prevent water from eroding the substrate layer 11, and the anti-corrosion layer 12 can alleviate the erosion and slow down the erosion rate, thereby increasing the service life. Since the water-absorbing resin material has high water absorption, the water that breaks through the waterproof layer 14 can be absorbed by the water-absorbing layer 13, so the erosion rate can be further slowed down.
