Abstract

The invention discloses a continuous laying and water-saving pressure testing construction method of a long-distance water pipe. The method comprises the steps of designing and manufacturing of a fabricated pipe pressure testing device, groove excavation, mounting of the water pipe, mounting of the fabricated pipe pressure testing device, construction of a water filling system, pipe water filling, pipe pressure testing, drainage and pipe connection. The defects in the traditional pressure testing technology are overcome, a large number of waste resources can be saved, pipe laying construction does not need to be stopped during pressure testing, and the method has the beneficial effects that the construction progress is quick, construction is safe and reliable, and construction cost is reduced.

Description

technical field [0001] The invention relates to the field of pipeline construction methods, in particular to a construction method for continuous laying of long-distance water pipelines and water-saving pressure testing. Background technique [0002] During the laying of the water pipeline, the pressure test must be carried out in sections, and the next section of the pipeline can only be laid after the pressure test of the previous section of the pipeline is qualified. That is to install a pipe section, pressure test a pipe section, and then the next pipe section, and the installation and pressure test reciprocate. Such laying of pipelines requires intermittent construction, and the back of the original soil must be reserved, and the back will be removed after the pressure test, and the construction process is cumbersome. The construction organization is complex and the project progress is slow. In addition, the pressure test water cannot be recycled, and a large amount o...
