The inner wall of the ring is in contact with the outer wall of the No. 1 tube body 1.

One end of the No. 1 pipe body 1 is installed with a sealing ring, and one end of the sealing ring is in contact with an end inside the No. 2 pipe body 2 .

Inflatable assembly 4 includes:

The gas ring is fixedly installed on the inner wall of the No. 2 pipe body 2. After the gas ring is inflated internally, the inner wall of the gas ring contacts the outer wall of the No. 1 pipe body 1;

The valve core is fixedly installed on the breather pipe of the gas ring, and one end of the valve core penetrates the inner wall of the No. 2 tube body 2.

The outer wall of the No. 1 pipe body 1 is provided with a groove, and the inner wall of the gas ring is in contact with the inner wall of the groove.

The outer wall of the No. 2 fixing ring 302 is fixedly connected with a clamping piece. One end of the limiting ring 304 is in contact with the inner wall of the clamping piece. A screw is installed on one side of the clamping piece. The clamping piece is fixed to the limiting ring 304 through the screws.

The sealing ring is squeezed during use, thereby reducing the gap between the first pipe body 1 and the second pipe body 2.

The No. 2 pipe body 2 and the No. 1 pipe body 1 have the same structure. They are both composed of two semicircular rings combined by bolts. When producing the No. 1 pipe body 1 and the No. 2 pipe body 2, the bellows are used to set up the pipes respectively. The outer walls of the No. 1 pipe body 1 and the No. 2 pipe body 2 are provided with placement grooves. The No. 1 fixing ring 301 is installed on the No. 1 pipe body 1 through the placement groove. The No. 2 fixing ring 302 is installed on the No. 2 pipe body 2 through the placement groove. On the other hand, the No. 1 semi-circular ring and the No. 2 semi-circular ring can be fixed by welding.

After the No. 1 pipe body 1 and the No. 2 pipe body 2 are spliced to each other, rotate the rotating clamp 303 so that one end of the rotating clamp 303 contacts one side of the No. 1 fixed ring 301, install the limiting ring 304, and install the screws. , the position of the screw makes it subject to less external force. Even if the screw is not installed, the limiting ring 304 can always be in this position under the clamping effect of the clamping piece and the rotating clamp 303.

Inflate the inner wall of the air ring through the valve core, thereby reducing the gap between the first tube body 1 and the second tube body 2, thereby ensuring the sealing of the connection between the first tube body 1 and the second tube body 2.

Through the use of the rotating clamp 303, when the first pipe body 1 and the second pipe body 2 tend to separate from each other, the rotating clamp 303 and the first fixed ring 301 are in contact, and the rotating clamp 303 changes this trend. The direction of action makes the trend direction become the direction of outward divergence due to the inside of the bellows, and the use of the restriction ring 304 can effectively prevent the divergence force. At the same time, due to the working place of the bellows, the surrounding soil will exert an influence on the restriction ring 304 pressure, thereby further exerting force on the rotating clamp 303, so that during the working process of the double-walled corrugated pipe, the possibility of displacement between the No. 1 pipe body 1 and the No. 2 pipe body 2 is low, ensuring that the double-walled corrugated pipe is The effect of using wall corrugated pipes.

Through the arrangement of the connecting component 3, when there is a tendency of phase separation between the No. 1 pipe body 1 and the No. 2 pipe body 2, the rotating clamp 303 clamps the No. 1 fixed ring 301, and the rotating clamp 303 itself rotates , when the No. 1 pipe body 1 and the No. 2 pipe body 2 have a tendency to separate, the rotating clamp 303 changes the direction of the trend, so that the direction of the trend becomes the direction of outward divergence from the inside of the bellows, and the ring is restricted. The use of 304 can fix the position of the rotating clamp 303 and avoid the rotation of the rotating clamp 303. The rotating clamp 303 exerts force on the restricting ring 304. At the same time, the existence of the clamp allows the restricting ring 304 to be fixed in the current position, and the screw The use of can further fix the position of the limiting ring 304, and even if the screws are loose, it will not affect the fixing effect of the connecting component 3 on the first tube body 1 and the second tube body 2; through the setting of the inflatable component 4, After the connecting assembly 3 fixes the No. 1 pipe body 1 and the No. 2 pipe body 2, inflate the inside of the air ring through the valve core, and the air ring expands with air intake, so that the No. 1 pipe body 1 and the No. 2 pipe body 2 When force is applied, the No. 1 pipe body 1 is forced to squeeze the No. 2 pipe body 2, and the No. 2 pipe body 2 is forced to squeeze the No. 1 pipe body 1, thereby reducing the size of the No. 1 pipe body 1 and the No. 2 pipe body. The gap between 2 ensures the sealing between the No. 1 pipe body 1 and the No. 2 pipe body 2.
