Abstract

The invention provides a corrugated steel pressure pipeline welding and sealing method, and belongs to the technical field of corrugated pipes. The corrugated steel pressure pipeline welding and sealing method comprises the steps of firstly assembling a plurality of connecting plate sheets into annular structures, temporarily fixing two adjacent connecting plate sheets through bolts, and fixing each connecting plate sheet through taper pins; then temporarily fixing the multiple annular structures through bolts, then detecting whether the mounting size between the two annular structures reachesthe standard or not, and after the mounting size reaches the standard, fixing the two adjacent annular structures through taper pins to form a corrugated pipe; and finally welding and sealing the joint of a first flange and a second flange. According to the corrugated steel pressure pipeline welding and sealing method provided by the invention, the shear capacity of the corrugated pipe is improved by means of the taper pins, then higher water pressure can be borne, later-period fixation can be conveniently conducted through the taper pins in a bolt temporary fixing mode, the installation of the corrugated pipe also can be facilitated, and meanwhile, the corrugated pipe can bear high water pressure due to the fact that welding sealing is adopted.

Description

technical field [0001] The invention belongs to the technical field of corrugated pipes, and more specifically relates to a method for welding and sealing corrugated steel pressure pipes. Background technique [0002] The corrugated steel plate is light in weight, can withstand large pressure loads, and is prefabricated in a factory, which can realize standardized production and processing, and is a good building structural material. The current installation of corrugated steel pipes relies on bolted connections, and gaskets are provided at the joints of the connecting plates, which can achieve low-pressure waterproof sealing, but the sealing effect is poor in high-water-pressure application scenarios. Contents of the invention [0003] The object of the present invention is to provide a method for welding and sealing corrugated steel pressure pipes to solve the technical problem of poor sealing effect of corrugated steel pipes in the prior art. [0004] In order to achie...
