Construction method for large-span pipe corridor pipeline

Abstract

The invention discloses a construction method for a large-span pipe corridor pipeline. The method comprises the following steps of: S1, manufacturing and installing a pipeline installation and welding protective shed; S2, installing two pulley blocks on pipe corridor truss columns, pairing pipeline segments 1 on the ground, wherein the length of the pipeline segments is greater than the distance between two adjacent pipeline support truss columns; S3, connecting a winch and a whole-pavement hydraulic crane with two sends of the pipeline segments 1 by virtue of steel wire ropes; S4, hoisting the pipeline segments 1 into proper positions on pipeline brackets by virtue of combination of the winch and the whole-pavement hydraulic crane; S5, hoisting the pipeline segments 2 to the pipeline brackets; and S6, welding so as to finish assembled welding of interfaces of the pipeline segments 1 and pipeline segments 2. The construction method for the large-span pipe corridor pipeline is capable of reducing displacement of the crane and increasing the use efficiency of the crane, not only is simple to manufacture, convenient to operate and high in applicability, but also is capable of reducing the construction cost and unsafe factors and ensuring the construction quality and safety.

Description

technical field [0001] The invention belongs to the field of pipeline construction, in particular to a construction method of a large-span pipe gallery pipeline. Background technique [0002] At present, due to the long straight-line installation distance of pipelines, within the allowable range of the selected hoisting machinery performance, frequent shifting is required in the construction area to meet the hoisting conditions, thereby reducing the use efficiency of the crane and increasing the cost of mechanical use; in addition, in some areas, Affected by the surrounding environment, the crane operating surface and space are limited, which brings many unfavorable and unsafe factors to personnel operation. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a construction method for large-span pipe gallery pipes, so as to solve the problems raised in the above background technology. [0004] To achieve the above object, the present inven...
