Abstract

The invention discloses an underwater repair method of a large-diameter HDPE pipeline. Through the manner that semicircular clamps cooperate with concrete packing, rubber plates are fixed to the to-be-repaired pipeline, rubber cloth is wound on the pipeline, water stop is carried out, underwater repair of the pipeline is carried out, no extra pipeline needs to be mounted, operation difficulty is small, the repair performance is high, economic performance is good, and the underwater repair method is suitable for underwater repair of the large-diameter HDPE pipeline. The underwater repair methodis used for the fields of port engineering, traffic engineering, water conservancy engineering and highway engineering.

Description

technical field [0001] The invention relates to the fields of port engineering, traffic engineering, water conservancy engineering, highway engineering and the like, in particular to an underwater repair method for a large-diameter HDPE pipeline. Background technique [0002] High-density polyethylene pipes (hereinafter referred to as HDPE pipes) are widely used in many fields such as water supply systems, water diversion systems, drainage systems, and gas transmission. After the underwater installation of the large-diameter HDPE pipe is completed, the connection of the pipe section may be damaged due to some force majeure factors. If using traditional techniques such as underwater cutting and then reinstalling, not only the construction process is complicated, but also the production cost of pipes and other materials is wasted. With the development of the economy, the application of large-diameter HDPE pipelines is bound to become more extensive. Therefore, it is necessary...
