[0027] The first connector 5 is provided with a first connection unit 10, and the second connector 6 is provided with a second connection unit 11 that cooperates with the first connection unit 10. The first connection unit 10 includes a plug rod 15, a limit slide plate 16, and a first spring 17. The first connector 5 is provided with a sliding cavity, the limit slide plate 16 is slidably arranged in the sliding cavity, the plug rod 15 is arranged on the limit slide plate 16 and is clamped and slidably penetrates through the sliding cavity. The cross-section of the plug rod 15 is elliptical. The second connector 6 is provided with a jack 12, and the plug rod 15 can be inserted into the jack 12. The first spring 17 is sleeved on the plug rod 15, and the two ends of the first spring 17 are respectively arranged on the limit slide plate 16 and the inner wall of the sliding cavity. A button 18 is arranged on the plug rod 15. The second connection unit 11 includes a pressure rod 19, a connecting plate 20, a fixed rod 21, and a second spring 22. A cavity and a chute are arranged in the second connector 6.

The fixed rod 21 can be inserted into the fixing hole 24; a slope 25 is arranged at the top of the fixed rod 21.

[0028] The pipeline main body 2 includes a polyethylene inner pipe 28, a polyethylene outer pipe 29, a first steel wire skeleton layer 30, a second steel wire skeleton layer 31, and a buffer layer 32.

[0029] During specific use, first insert the plug 3 of a group of pipeline main bodies 2 into the slot 4 of another group of pipeline main bodies 2 connected thereto, and make the first connectors 5 and the second connectors 6 on the two groups of pipeline main bodies 2 dock together. Then, by pressing the button 18, the plug rod 15 is inserted into the jack 12, and the first spring 17 is compressed. During the process of inserting the plug rod 15 into the jack 12, the plug rod 15 will slide along the slope 25 and continuously press the fixed rod 21 to move downward, so that the second spring 22 is compressed. Until the fixed rod 21 is inserted into the fixing hole 24, the first connector 5 and the second connector 6 can be connected together. At this time, the preliminary connection and fixation of two adjacent groups of pipeline main bodies 2 are realized. Then, dock the first flange 7 and the second flange 8 on the two groups of pipeline main bodies 2 together, and fix the first flange 7 and the second flange 8 through the bolt 9, so as to realize the further connection and fixation of two adjacent groups of pipeline main bodies 2.

By setting the buffer layer 32 between the first steel wire skeleton layer 30 and the second steel wire skeleton layer 31, the impact resistance of the pipe can be significantly improved. Since the buffer layer 32 has certain elasticity and toughness, it can effectively absorb and disperse energy when being impacted, and disperse the impact force through its own deformation, so as to protect the pipe from damage.

[0032] In summary, this solution is provided with a connection structure 1. Through the connection structure, two adjacent pipeline main bodies 2 can be quickly connected together. At the same time, through double connection reinforcement, the connection effect is better, and it is also convenient to demolish the connected pipeline main bodies 2, so as to more conveniently replace the pipeline main bodies 2; this solution can effectively improve the strength of the pipe by setting a double-layer steel wire skeleton, and at the same time, a buffer layer 32 is set between the two layers of steel wire skeletons, which can significantly improve the impact resistance of the pipe.
