Abstract

The invention relates to the field of pipelines, and particularly to a winding pipe capable of sealing a gap by expanding and a mounting method thereof. The winding pipe capable of sealing the gap by expanding comprises a pipe body and a plurality of rubber strips, wherein the plurality of rubber strips are arranged on the outer side of the pipe body; the rubber strips are made from a water-expandable material; the pipe body comprises a first connecting pipe, a second connecting pipe and a telescopic pipe; and the first connecting pipe is connected with the second connecting pipe through the telescopic pipe. According to the winding pipe capable of sealing the gap by expanding and the mounting method thereof, the plurality of rubber strips are arranged, the raw materials of the rubber strips comprise the water-expandable material, the rubber strips can expand in the presence of water to be increased in the volume, so that the rubber strips with the volume being increased can seal the gap between the winding pipe capable of sealing the gap by expanding and a surrounding filling structure thereof, and water or a fluid is prevented from leakage; and besides, the telescopic pipe can overcome the deformation stress of the pipe body in the axial direction, and the fracture risk of the pipe body due to shrinkage is reduced.

Description

technical field

[0001] The invention relates to the field of pipelines, in particular to a winding pipe capable of expanding and sealing gaps and an installation method thereof. Background technique

[0002] At present, in the water supply and drainage pipeline system, the winding reinforced pipe has gradually become the mainstream pipe material, and occupies a very important position in the water supply and drainage pipeline engineering. In the prior art, due to the material of the pipeline itself (such as HDPE winding pipe which can expand and close the gap) and the structure of the pipeline. During the installation of the coiled pipe capable of expanding and sealing gaps, surface or underground water may leak from the joint between the coiling pipe capable of expanding and sealing gaps and concrete. Contents of the invention

[0003] The object of the present invention is to provide a winding pipe that can expand and seal the gap and its installation method, which aims...
