Referring to fig. 5, the extension seat 9 includes a butting plate 91 butted against the positioning plate 5 and an L-shaped connecting rod 92 fixed on the sidewall of the butting plate 91 close to the positioning plate 5, the sidewall of the positioning plate 5 is provided with a connecting groove 54, the connecting rod 92 is inserted into the connecting groove 54, and the sidewalls of the positioning plate 5 and the butting plate 91 close to the duct unit 21 both form an arc-shaped groove 10 matched with the duct unit 21; when the liquid is transported, the pipeline unit 21 extrudes the supporting block 4 and descends, and the arc-shaped groove 10 can be abutted against the side wall of the pipeline unit 21 and attached to the side wall of the pipeline unit 21, so that a stable positioning effect is achieved.

A construction process of a novel municipal road pipe network comprises the following steps:

s1, after an underground pipeline 1 is excavated to form an installation groove 11, fixing supporting blocks 4 which are opposite to each other at intervals along the length direction of the bottom of the installation groove 11, respectively spacing a set positioning groove 111 on the side wall of the installation groove 11, forming a matching groove 112 above the positioning groove 111, then inserting a prefabricated insertion plate 51 with a tension spring 52 and a positioning plate 5 into the positioning groove 111 in an insertion mode, and then inserting a pressing plate 6 with a supporting spring 61 into the matching groove 112;

s2, respectively inserting the sliding strips 721 on different connecting blocks 72 into the sliding grooves 2121 on the corresponding sides of the pipeline units 21, installing the connecting blocks 72 in the through grooves 212, and enabling the bottoms of the pressure levers 8 to abut against the abdicating surfaces 722 on the connecting blocks 72; placing a pipeline unit 21 on the supporting block 4, enabling the positioning plate 5 and the pressing plate 6 to abut against the corresponding position of the side wall of the pipeline unit 21, then placing another pipeline unit 21 at an adjacent position, and pushing the adjacent ends of the two pipeline units 21 to move oppositely, so that the connecting lantern ring 71 is inserted into the annular groove 211, and the extending plate 213 is inserted into the through groove 212 until abutting against the side wall of the connecting block 72; then, the pressure lever 8 is pressed downwards, the connecting block 72 is pushed out to be clamped on the side walls of the connecting sleeve ring 71 and the sealing ring 711, adjacent pipeline units 21 are connected and positioned, and the whole pipe body 2 is connected in the same way;

s3, when carrying liquid, body 2 extrudees supporting shoe 4 under liquid weight, and supporting shoe 4 deformation makes body 2 descend, and the arc wall 10 laminating of locating plate 5 and butt correspond department in the lateral wall of body 2 this moment, and 6 butts in the top of body 2 of clamp plate, and supporting shoe 4 also plays limiting displacement to the bottom of body 2, and body 2 is stabilized positioning.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
