[0034] In this embodiment, if Figure 1-3 As shown, first, a layer of concrete base 2 is laid on the bottom surface of the groove, and a prefabricated steel plate abutment seat 3 is embedded in the concrete base 2. The prefabricated steel plate abutment seat 3 is arranged at intervals according to the forward direction of the installation of the pipeline 1. Then, before the installation of the pipeline 1, a prefabricated counterweight block 4 is cast in situ at a nearby site. A plurality of prefabricated counterweight blocks 4 are placed between the end face of the pipeline 1 and the prefabricated steel plate abutment seat 3. A jack 5 is installed on the prefabricated counterweight block 3 close to the end face of the pipeline 1. The friction force of the prefabricated counterweight block 4 and the reverse resistance of the steel plate abutment seat 3 act as a backrest for the jack 5. Then, the horizontal thrust of the jack 5 is used to tightly connect the end face of the pipeline 1 to be installed with the installed pipeline 1.

[0035] Prefabricated steel plate abutment seats 3 are installed on both sides of the pipeline 1, and two jacks 5 are respectively abutted on the end faces of the pipeline 1 at the same height. When the pipeline 1 is a DN2000 reinforced concrete grade III F-type steel socket pipe and the weight of a single section of the pipeline is 8T, the prefabricated steel plate abutment seats 3 can be set every 8 meters, and the jacks 5 can be 20T grade, and the top position of the jacks 5 is on the end face of the pipeline 1 at a height of 80cm from the concrete base surface 2.
