[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0019] Reference Figure 1-Figure 3A high pressure-resistant and wear-resistant double-wall corrugated pipe comprises a corrugated pipe 1. The high pressure-resistant and wear-resistant double-wall corrugated pipe is composed of two layers of pipe walls of different materials, one of which is an inner wall and the other is an outer wall, and the two layers are connected by corrugations. The left side wall of the corrugated pipe 1 is fixedly connected with an outward extension ring 2, and the right side wall of the corrugated pipe 1 is fixedly connected with an inward contraction ring 10. The left outer side wall of the corrugated pipe 1 is sleeved and fixed with a reinforcement hoop 4, and the top of the reinforcement hoop 4 is provided with an opening. The top of the reinforcement hoop 4 is fixedly connected with two reinforcement blocks 7 in contact with the opening. The two reinforcement blocks 7 are provided with threaded holes 11. The two reinforcement blocks 7 include bolts 6 threadedly connected with the threaded holes 11. The outer side wall of the corrugated pipe 1 is coated with a surface coating 12. The diameter of the outward extension ring 2 is larger than that of the inward contraction ring 10. The reinforcement block 7 is located directly above the opening. The outer wall thickness of the corrugated pipe 1 is increased. Increasing the thickness of the outer wall can improve the wear resistance of the pipe. By increasing the thickness of the outer wall, the pipe can To better resist external impact and wear, the bellows 1 is made of high-density polyethylene material, which can effectively resist wear and erosion of particles and extend the service life of the pipeline. The surface coating 12 is made of rubber coating, which can provide an additional protective layer to improve the wear resistance of the pipeline. When two bellows 1 need to be installed and fixed, first place the first bellows 1 in the ground where it needs to be installed, and then place the second bellows 1 behind the protruding ring 2 of the first bellows 1 in the direction of the inward-retracting ring 10, and then push the second bellows 1 to make the inward-retracting ring 10 pass through the protruding ring 2 of the first bellows 1. When the inward-retracting ring 10 moves to the reinforcement hoop 4 of the first bellows 1, the bolt 6 is twisted to make it threadedly connected with the threaded hole 11, so that the reinforcement hoop 4 shrinks inward to make the inner wall of the first bellows 1 contact with the outer wall of the second bellows 1, and then the reinforcement installation is completed.
[0020] A reinforcement ring 8 is fixedly mounted on the right outer wall of the bellows 1, a plurality of welding blocks 2 9 are fixedly connected to the left side wall of the reinforcement ring 8, a plurality of welding blocks 1 3 are fixedly connected to the right side wall of the reinforcement hoop 4, a reinforcement sleeve 5 mounted on the outer side wall of the bellows 1 is welded to the outer side walls of the plurality of welding blocks 1 3, a right side wall of the reinforcement sleeve 5 is welded to the left side wall of the welding block 2 9, a plurality of welding blocks 1 3 and welding blocks 2 9 are evenly distributed on the outer side walls of the reinforcement hoop 4 and the reinforcement ring 8, the reinforcement sleeve 5 can effectively improve the wear resistance of the bellows 1, so that the bellows 1 can better resist external impact and wear, and extend the service life of the pipeline.
