[0002] The design of the drainage system of cold-region tunnels is crucial to the normal use and safe operation of the tunnels. Once the drainage system fails and cannot perform drainage work, the safety of the tunnel cannot be guaranteed.

[0028] Combination Figure 8The present embodiment is further improved on the basis of the embodiment 2 in that: an anti-freezing and blocking drain pipe suitable for use in a cold environment comprises a drain pipe body 1, a water pipe 47 is wound around the outside of the drain pipe body 1, a water tank 48 is arranged on the outside of the drain pipe body 1, a plurality of heating pipes 49 are fixed to the inner wall at the bottom of the water tank 48, a pump body 50 is fixed to the outside of the water tank 48, one end of the water pipe 47 is connected to the output end of the pump body 50, the other end of the water pipe 47 extends to the inside of the water tank 48, the input end of the pump body 50 is connected to the water inlet pipe 51, and the water inlet pipe 51 is away from the pump body 50. The end extends to the interior of the water tank 48. A liquid level valve is installed on the outside of the water tank 48. A sufficient amount of water can be injected into the water tank 48 through the liquid level valve. The water inside the water tank 48 can be heated by the operation of the heating tube 49. The operation of the pump body 50 can drive the water inlet pipe 51 to extract hot water from the water tank 48. At this time, the hot water extracted by the water inlet pipe 51 will be transported to the water supply pipe 47.

[0029] Working principle: prepare the material, convey the prepared material to the extruder, melt and extrude the material through the extruder, pull the material into the cooling mold through the clamp, cool and mold the material through the cooling mold, and then install the drain pipe body 1 inside the processing equipment. Then, the output shaft 4 can be driven to rotate through the operation of the motor 1, and the conveying roller 15 can be driven to rotate, and the drain pipe body 1 can be driven to move. At this time, the displaced drain pipe body 1 will push the connecting plate 121 to move. At this time, the displaced connecting plate 121 will drive the loading block 22 and the rack plate 120 to move. At this time, the displaced rack plate 120 will drive the driving gear 19 to rotate, and drive the driving shaft 15 to rotate. At this time, Through the cooperation of bevel gear 17 and bevel gear 2 18, the driving shaft 14 is driven to rotate, and at this time, the cutting blade 6 can be driven to rotate by the rotating driving shaft 14, and at this time, the drain pipe body 1 between the supporting sleeve 7 and the supporting cylinder 8 can be cut by the rotating cutting blade 6, and when the cutting blade 6 cuts the drain pipe body 1, the drain pipe body 1 can be supported by the supporting sleeve 7 and the supporting cylinder 8 to avoid deformation of the cutting edge of the drain pipe body 1 when the drain pipe body is cut by the cutting blade 6, thereby improving the flatness of the cutting edge of the drain pipe body 1 and the product quality of the drain pipe body 1, and the drain pipe body 1 can be limited by the supporting sleeve 7 and the supporting cylinder 8 to avoid deformation when the drain pipe body 1 is cut. The drain pipe body 1 is offset, which improves the stability of the drain pipe body 1. After the cutting of the drain pipe body 1 is completed, the output shaft 2 10 can be driven to rotate through the operation of the motor 2, and the conveying roller 2 11 can be driven to rotate. At this time, the supporting cylinder 8 can be driven to move through the rotating conveying roller 2 11. When the supporting cylinder 8 is separated from the interior of the drain pipe body 1, the cut drain pipe body 1 is discharged. Then, the output shaft 1 4 is driven to rotate through the operation of the motor 1, and the conveying roller 1 5 is driven to rotate to drive the drain pipe body 1 to move. When the drain pipe body 1 contacts the connecting plate 1 21, the above work is repeated to continue cutting the drain pipe body 1. When the drain pipe body 1 is separated from the supporting cylinder 8, the drain pipe body 1 will be The drain pipe body 1 falls into the receiving box 34. At this time, the cut drain pipe body 1 can be received by the receiving box 34. Then, the screw rod 35 can be rotated, and the screw rod 35 and the driving sleeve can cooperate with each other through the thread, so as to drive the driving sleeve and the push plate to move. At this time, the drain pipe body 1 inside the receiving box 34 can be pushed by the displaced push plate to discharge the drain pipe body 1 out of the receiving box 34, so as to facilitate the staff to receive the cut drain pipe body 1, and then the cut drain pipe can be quality inspected and packaged. When the drain pipe body 1 needs to be used for drainage, the water inlet pipe 51 can be wrapped around the outside of the drain pipe body 1. When the drain pipe body 1 works in a cold environment, a sufficient amount of water can be injected into the water tank 48. Through the operation of the heating pipe 49,The water inside the water tank 48 can be heated. The operation of the pump body 50 can drive the water inlet pipe 51 to extract hot water inside the water tank 48. At this time, the hot water extracted by the water inlet pipe 51 will be transported to the inside of the water delivery pipe 47. At this time, the hot water running inside the water delivery pipe 47 will emit heat, thereby heating the drainage pipe body 1 to prevent the water inside the drainage pipe body 1 from freezing in a cold environment.
