Abstract

The invention discloses a method for remotely pumping thick cement slurry through a relay method, which comprises the following steps: equipment type selection, pipeline erection, communication equipment debugging, testing, stirring, pumping and cleaning, wherein a 7 Mpa double-layer high-pressure pipe is selected as a double-layer high-pressure pipe, a fixed support is additionally arranged between the pipeline and a stair railing every 10 m, a buffer barrel is additionally arranged at the position of each relay grouter and is used for temporarily storing cement grout in a pipeline when grouting is suspended. According to the method for remotely pumping the thick cement slurry through the relay method, the construction efficiency is greatly improved, the thick cement slurry transportation speed is high, the construction period is shortened, due to the fact that pipeline transportation is adopted, worker operation is reduced, the personnel organization difficulty caused by cross operation is reduced, pollution to completed structures is reduced, particularly dip dyeing of contact nets is reduced, the workload of secondary cleaning is reduced, and the cleaning cost is reduced.

Description

technical field [0001] The invention relates to the field of engineering construction, in particular to a relay method for long-distance pumping of cement thick slurry. Background technique [0002] In the later stage of the subway construction, all the reserved hoisting holes have been closed, and the cement cannot be lifted mechanically. In view of the void behind the subway tunnel segment and the large water leakage, it is necessary to transport the cement to the site and pour the cement slurry through the screw pump to solve the problem. Sometimes the cement can only be manually moved through the stairs and transported to the construction site by small trucks. Therefore, a large number of workers are required, the organization is difficult, and the construction cost is high. It is not conducive to the protection of completed buildings and increases the pollution to the construction site. Contents of the invention [0003] The purpose of the present invention is to prov...
