Abstract

The invention relates to the technical field of pipeline laying and provides water application pipeline laying facility which comprises a first water retaining wall mounted at an entrance port of a sleeve, wherein a pipeline-through hole for penetrating into a pipeline is formed in the first water retaining wall. When the water application pipeline laying facility is applied to pipeline laying, after the end part of the to-be-laid pipeline penetrates into the pipeline-through hole in the first water retaining wall, liquid can be injected into a liquid accommodating chamber. At the moment, the pipeline entering the sleeve undergoes vertical upward buoyancy, then the acting force for a pipeline laying process is reduced, the requirements on the laying equipment as well as the operation complexity are lowered, the construction safety and laying speed are improved, and the pipeline is laid in place for sure. Moreover, since a support member is mounted in advance and then drives the pipeline to enter the sleeve, the damage and deformation of the support member can be prevented; meanwhile, the frictional resistance against the pipeline is reduced under the buoyancy, and thus the pipeline is effectively protected from outer corrosion.

Description

Technical field [0001] The invention relates to the technical field of pipeline laying, and provides a water laying method pipeline laying facility. Background technique [0002] In the construction of the municipal supporting pipeline project on Cuihu East Road (North Side Road of Jingmi Water Diversion Canal-Cuihu South Road) in Haidian District-the reclaimed water project, the reclaimed water pipeline passes through Beiqing Road, the landscape river is planned and the Dazhai Canal section is planned. Among them, the reclaimed water pipelines corresponding to Beiqing Road, the planned landscape river and the planned Dazhai canal section are 133.5m, 97.5m and 65.5m long respectively. Since the construction site does not have the open slot condition, the prior art proposes to install the casing in place by the jacking method first, and then lay the reclaimed water pipeline in the casing. [0003] See figure 1 , The casing adopts a reinforced concrete casing with a diameter of 3000...
