Abstract

The invention belongs to a buried pipe compensating device, in particular relates to a buried pipe stretcher. A coil pipe is sleeved to and fixed to an upright post of a bracket which is arranged in a cylinder together with the coil pipe, end covers are respectively fixed at both ends of the cylinder, both ends of the bracket are respectively inserted in pin shaft holes in the end covers, and both ends of the coil pipe respectively extend out from both end holes of the cylinder. The invention has the advantages that the stretching problem of the buried pipe can be thoroughly solved by compensating the stretched buried pipe with the stretcher so as to prevent a pipeline from being twisted, stretched to be deformed, cracked to run water or even broken because of the stretching and the deformation of the buried pipe in the service life of a ground source heat pump and ensure the normal use of the buried pipe.

Description

technical field

[0001] The invention belongs to a buried pipe compensation device, in particular to a buried pipe tensioner. Background technique

[0002] With the maturity of ground source heat pump technology and the development in China in the past ten years, it has begun to be gradually used in actual production and life. From the perspective of distribution, most of them are in the inland or coastal areas, but these areas are rocky or conventional. Areas with good soil and other geological conditions.

[0003] With the global warming and the introduction of national energy conservation and emission reduction policies, the use of ground source heat pumps is becoming more and more popular, and soft soil subsidence generally occurs near the piers or beaches formed by artificial dredging in Tianjin Port. The characteristics of this kind of ground are: the ground surface is slightly higher than sea level, and the groundwater resources are very rich and complex, even includi...
