Pipe-burying method for soil source heat pump system and soil source heat pump system

The invention provides a pipe-burying method for a soil source heat pump system and the soil source heat pump system. The pipe-burying method for the soil source heat pump system comprises the steps that vertical pipe-burying is performed in pile foundations, wherein first heat exchange pipes are prefabricated in the pile foundations, in detail, the first heat exchange pipes are pre-arranged in reinforcement cages of the pile foundations, and then concrete is poured into the reinforcement cages to form the pile foundations; vertical pipe-burying is performed between the pile foundations, wherein second heat exchange pipes are buried between the pile foundations; the first heat exchange pipes are communicated with the second heat exchange pipes through horizontal manifolds. According to the pipe-burying method for the soil source heat pump system, the heat exchange pipes can be arranged at the bottom of a building, and therefore the space at the bottom of the building is effectively utilized.
