Description

[0001] The present application relates to the technical field of ground source heat pump pipeline construction, in particular to a shallow ground source heat pump pipeline temporary fixing protection device. BACKGROUND

[0002] After the horizontal pipe and vertical pipe of the ground source heat pump under the foundation pit are constructed, the fixed horizontal pipe and vertical pipe usually have no stretchable margin, during backfilling and compaction of the vertical pipe root and the backfilling trench, the backfilling soil compaction causes the pipeline to stretch downward, which easily leads to deformation of the buried pipeline caused by vertical force, resulting in pipeline damage, and the pipeline cannot be effectively protected.
