Document Type and Number:
WIPO Patent Application WO/2023/286935
Kind Code:
A1
Abstract:
The present invention relates to a structure pipe thawing system using hot water and, specifically, to a structure pipe thawing system using hot water that can quickly and efficiently thaw a frozen pipe portion by using hot water even when a buried pipe is bent in various ways, can quickly and efficiently thaw a frozen pipe portion by dividing the reuse of melt water into an immediate reuse and a reuse after heating according to the temperature of the melt water, can automatically control the operation of the thawing system for a frozen pipe portion through a control unit configured to control the injection and recovery of hot water, etc. at intervals that are set on the basis of the length of the entire pipe and the length of the frozen pipe portion of the pipe, and particularly can quickly and efficiently thaw a frozen pipe portion by actively controlling the system according to a site situation and progress by adjusting/controlling the intervals of injection and recovery of hot water, etc. that are controlled for thawing according to the temperature of the hot water or melt water recovered through an injection pipe or a recovery pipe, the distance from a pipe inlet to a frozen pipe portion, or the degree of thawing in the thawing process.
