Connector-free buried pipe heat exchange assembly in foundation pit and construction technology

Abstract

The invention relates to the technical field of energy, in particular to a connector-free buried pipe heat exchange assembly in a foundation pit and a construction technology. The technology comprisesthe steps that the vertical section of a buried pipe is laid in the foundation pit; the horizontal section of the buried pipe is laid after the vertical section of the buried pipe is laid; the perpendicular section of the buried pipe is laid after the horizontal section of the buried pipe is laid; and after the perpendicular section of the buried pipe is laid, the ground section of the buried pipe is laid to a sub-catchment device. A buried hole of a buried pipe heat exchange system is arranged in the foundation pit of a building, the problem that the buried pipe heat exchanger arrangement area around the building is insufficient is effectively solved, the buried pipe heat exchange system is provided with no connector, the problem that the welding spot leakage risk is caused since hot melting, electric melting and other conventional connection ways are adopted for the buried pipe heat exchange system in the foundation pit is effectively avoided, and construction quality and operationsafety of the buried pipe heat exchange system are ensured.

Description

technical field [0001] The invention relates to the field of energy technology, in particular to a non-joint buried pipe heat exchange component in a foundation pit and a construction process. Background technique [0002] At present, the development and application of renewable energy has attracted much attention. Ground-source heat pumps with buried pipes can use shallow geothermal energy to meet the demand for cooling and heating loads of buildings, which has good energy saving and environmental protection. Arranging buried tube heat exchangers in building foundation pits is one of the effective ways to solve the insufficient layout area of ​​buried tube heat exchangers around buildings. At this time, the pressure of the pipes of the buried pipe heat exchange system is relatively high. If the connection methods such as conventional thermal fusion or electric fusion are adopted, the water supply and return pipes in the heat exchange holes of the buried pipes are connected ...
