Method for laying pulp pipelines in marsh district

Abstract

The invention discloses a method for laying pulp pipelines in a marsh district, which is simple, convenient and rapid. The method disclosed by the invention comprises the following steps: A. digging a pipe ditch in the marsh district and arranging a pipeline floating region and a pipeline assembling region in the region at the external side of the pipe ditch, wherein the height above sea level ofthe pipeline assembling region is higher than that of the pipeline floating region; B. injecting water into the pipeline floating region and the pipe ditch; C. enabling N pipelines to float on the water surface of the pipeline floating region after being assembled into a pipeline line in the pipeline assembling region; and D. enabling the pipe line in the step C to be floated into the reserve installing position in the pipe ditch from the pipeline floating region and finally enabling the pipe line to be sunk at the bottom of the pipe ditch. Because the pipe line is moved through floating, thedegree of movement freedom of the pipe line is high and the movement is rapid and convenient, thus the laying course of the integral pipe line is convenient, simple and rapid and has the advantages of time and labor conservation, high safety and low cost.

Description

technical field [0001] The invention relates to a method for laying a slurry pipeline, in particular to a method for laying a slurry pipeline in a swamp area. Background technique [0002] At present, when laying slurry pipelines in swampy areas, multiple pipelines are first welded into pipelines on dry ground, and then slides are erected on the moving path of the pipelines. After the pipelines are hoisted onto the slides, 5 rocket engines are tied on the pipelines. Ignite 3 rocket engines at a time, and use the thrust of the rocket engine to project the pipeline 300 to 500 meters along the slideway until the pipeline is moved to the inside of the trench, and then set up the slideway inside the trench, and then use the same The method is to move the pipeline to the predetermined installation position for installation until all the pipelines to be laid in the pipe trench in the section are installed. The above method has the following disadvantages: 1. It is necessary to ins...

AI Technical Summary

Problems solved by technology

The above method has the following disadvantages: 1. It is necessary to insulate the surface of the pipeline corresponding to the tail of the rocket engine, which is complicated in technology and high in construction cost; 2. The rocket engine after ignition must be refilled with fuel, which is more dangerous. It is time-consuming and labor-intensive to hire rocket engine experts; 3. The requirements for the slideway are very high; 4. Each launch is expensive and costly; 5. The preparation time before each ignition of the rocket engine is long, which makes the entire pipeline laying cycle longer
