Description

Technical Field

[0001] The utility model relates to the technical field of double-wall corrugated pipes, in particular to a double-wall corrugated pipe with a compression-resistant structure. Background Art

[0002] Double-wall corrugated pipes can be used for water supply, drainage, sewage discharge, and exhaust. They have a wide range of applications. They also have the characteristics of light weight, small drainage resistance, and high compressive strength. Therefore, there is a large demand for their use. At present, double-wall corrugated pipes are very mature in production technology and use technology, and have been greatly promoted and applied.

[0003] The connection of double-walled corrugated pipes mainly uses the socket connection method. Although the socket connection method is simple and quick, and the ends of the double-walled corrugated pipes can be directly inserted into each other, the stability and sealing after the connection are low. When the double-walled corrugated pipe is used to transport the medium and is subjected to impact force, long-term use will cause the connection end of the double-walled corrugated pipe to loosen, and the gap at the connection end of the double-walled corrugated pipe will increase, causing medium leakage. Therefore, we proposed a double-walled corrugated pipe with a pressure-resistant structure to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of the utility model is to provide a double-walled corrugated pipe with a pressure-resistant structure to solve the problem that the socket-type connection method of double-walled corrugated pipes on the current market has low stability and sealing, and when the double-walled corrugated pipe is used to transport the medium and is subjected to impact force, long-term use will cause the connection end of the double-walled corrugated pipe to loosen, and the gap at the connection end of the double-walled corrugated pipe will increase, resulting in medium leakage.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a double-walled corrugated pipe with a compression-resistant structure, comprising a double-walled corrugated pipe body, the double-walled corrugated pipe body comprising an annular outer wall, a smooth inner wall, a metal wire mesh and reinforcing ribs, the inner side of the annular outer wall is connected to the smooth inner wall, the smooth inner wall and the annular outer wall are filled with a metal wire mesh, and the smooth inner wall and the annular outer wall are connected with reinforcing ribs;

[0008] Preferably, a rubber airbag is bonded to the outer side of the fixing ring, an air pipe is connected to the inside of the rubber airbag, one end of the air pipe is connected to a sealing airbag, and the sealing airbag is bonded to the inner wall of the large-mouth section.

[0009] Preferably, the reinforcing ribs pass through the metal wire mesh and are connected between the annular outer wall and the smooth inner wall. The reinforcing ribs and the raised ends of the annular outer wall are staggered. The reinforcing ribs and the metal wire mesh can be used to improve the compression and fracture resistance of the double-wall corrugated pipe.

[0010] Preferably, the movable rod is slidably connected to the fixed ring, and a driving rod is slidably penetrated through the outer side of the fixed ring. The movable rod can be used to drive the adjusting rod to drive the driving rod to move, so as to adjust the position of the reinforcement plate.

[0011] Preferably, the reinforcement plate is a "concave" shaped structure, and the reinforcement plates are distributed at equal angles about the center line of the large mouth section, so that the reinforcement plates are stuck in the groove outside the small mouth section to connect and reinforce the spliced ​​double-wall corrugated pipes.

[0012] Preferably, the moving ring is sleeved on the outside of the large mouth section, and the inner diameter of the moving ring is larger than the outer diameter of the large mouth section, which can ensure the smooth movement of the moving ring outside the large mouth section and drive the moving rod to move.

[0013] Preferably, the sealing airbag and the rubber airbag are interconnected through an air pipe. The sealing airbag is distributed between the movable ring and the fixed ring. The rubber airbag can be used to inflate the sealing airbag so that the sealing airbag bulges and fits against the spliced ​​end of the double-wall corrugated pipe, thereby improving the sealing performance of the double-wall corrugated pipe.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

When the moving ring moves, the rubber airbag can be squeezed to fill the airflow into the sealing airbag, so that the sealing airbag bulges and fits with the splicing end of the double-walled corrugated tube, thereby improving the sealing of the double-walled corrugated tube and preventing leakage at the connection end of the double-walled corrugated tube.
