[0021] Among them, a transport pipe assembly 11 is fixedly installed in the ditch and embedded in the ground through the positioning assembly 12, the sealing ring assembly 21 is inserted into the end with a flange on the transport pipe assembly 11, and then the end with a flange on the other transport pipe assembly 11 is inserted into the sealing ring assembly 21, and the positioning assembly 12 at the bottom of the other transport pipe assembly 11 is embedded in the ground. At this time, a short bolt 22 is used to penetrate and connect the sealing ring assembly 21 and a group of transport pipe assemblies 11, wherein the sealing ring assembly 21 is located in the middle position of a group of transport pipe assemblies 11, which can play a role in sealing and fixing a group of transport pipe assemblies 11, and a long bolt 3 is passed through a group of positioning assemblies 12, so that a group of transport pipe assemblies 11 can be reinforced and connected, and at the same time, the long bolt 3 can support the flange end of a group of transport pipe assemblies 11.

[0022] Specifically, the transport tube assembly 11 includes a transport tube body 111 , one side of the transport tube body 111 is fixedly connected with a flange 112 , and a notch 113 is formed on the lower side of the flange 112 .

[0024] Specifically, the sealing ring assembly 21 is embedded in a position between a group of flanges 112 , and the long bolts 3 penetrate through and are fixed on a group of support frames 121 .

[0025] As can be seen from the above, by embedding the positioning cone 122 into the ground, the support frame 121 can be prevented from moving, and the support frame 121 can support the transport tube body 111. By passing the long bolt 3 through and fixing it on a group of support frames 121, a group of transport tube bodies 111 can be further fixedly connected.
