Buried pipe stretcher

Abstract

The invention belongs to a buried pipe compensation device and relates to a buried pipe stretcher. A coiled pipe is mounted on a stand column of a support in a sleeving manner and fixed to the stand column of the support. The support and the coiled pipe are arranged in a barrel. End covers are fixed to the two ends of the barrel correspondingly. The two ends of the support are inserted into pin shaft holes in the end covers. The two ends of the coiled pipe extend out of holes in two ends of the barrel. The buried pipe stretcher has the beneficial effects that when a buried pipe is stretched, compensation can be achieved through the stretcher, and buried pipe stretching problems which are found are solved thoroughly; it is guaranteed that within the service life of a ground source heat pump, the problems of pipe distortion, tensile deformation, crack and water leakage and even fracture caused by tensile deformation of the buried pipe are avoided; and normal use of the buried pipe is guaranteed.

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...

AI Technical Summary

Problems solved by technology

Especially since the buildings are piled first and then the buildings are built, it is easy to cause the settlement of the building and the buried pipe to be inconsistent, that is, the settlement of the building body is small, and the settlement of the buried pipe is large, resulting in the stretching of the buried pipe. , when the stretching amount reaches a certain value, it is easy to cause the deformation of the buried pipe, so that the pipe is twisted, stretched, cracked, leaked, or even broken, which seriously affects the normal use of the ground source heat pump.

Even if remedial measures are taken, that is, to dig out the surface soil, find the place where the buried pipe leaks and then remedy it, but it is laborious and laborious, and it cannot guarantee good operation in the future.
