Hot melt sleeve and production tool, production method, storage and transport method and construction method

Abstract

The invention discloses a hot melt sleeve and a production tool, a production method, a storage and transport method and a construction method. The hot melt cover comprises a seamless rubber sleeve. Afirst mesh strip is arranged on the edge of the inner side face of one end of the seamless rubber sleeve along a peripheral direction; two ends of the first mesh strip are close to each other; a first live wire electrode is arranged at one end of the first mesh strip; a first zero line electrode is arranged at the other end of the first mesh strip; a second mesh strip is arranged on the edge of an inner side face of the other end of the seamless rubber sleeve along a peripheral direction; two ends of the second mesh strip are close to each other; a second live wire electrode is arranged at one end of the second mesh strip; and a second zero line electrode is arranged at the other end of the second mesh strip. The hot melt sleeve disclosed by the invention does not cause any crack due to the thickness of the hot melt sleeve, and sealed fixed connection between the hot melt sleeve and a thermal insulation pipe is facilitated; and meanwhile, the production tool used for producing the hotmelt sleeve is small in floor space; and the hot melt piece is simple in production method, and the production efficiency is high.

Description

technical field [0001] The present invention relates to a sealing connection part used for thermal insulation joints of directly buried high-temperature hot water pipe networks in heating projects, a production tool for the sealing connection part, a production method for the sealing connection part, a storage and transportation method for the sealing connection part, the A construction method for a sealed connection part, in particular to a heat-melt sleeve, a production tool for a heat-melt sleeve, a production method for a heat-melt sleeve, a storage and transportation method for a heat-melt sleeve, and construction of a heat-melt sleeve method. Background technique [0002] Since the introduction of foreign prefabricated direct-buried thermal insulation pipes in my country in the 1980s, the construction technology of direct-buried heating and thermal insulation pipes in my country has developed rapidly. Progress; With the popularization of high-temperature hot water pipe...

Problems solved by technology

[0008] The hot-melt sheet in the prior art needs to be sealed by lapping the two wide sides, so the gap caused by the thickness of the hot-melt sheet cannot be avoided, and it cannot be completely eliminated; at the same time, it is used to produce heat The production tools of the fusion sheet occupy a large area; the production method of the hot-melt sheet is more complicated and the production efficiency is low; the storage and transportation of the hot-melt sheet need to occupy a separate space; the construction method of the hot-melt sheet is more complicated and the construction efficiency is lower
