The buried pipe heat exchange system, especially the vertical buried pipe heat exchange system, is especially suitable for the national conditions of less land and more people in China due to small occupied area and large heat exchange amount, and is a main form for applying shallow geothermal energy in China. At present, large-scale shallow geothermal energy resources are developed and utilized in a large scale, and the construction scale tends to be larger and larger. The larger the project size, the higher the requirement for underground environment, the greater the requirement for underground space in the drilling area, and especially if a large number of borehole heat exchangers are concentrated in one land, a larger area of underground space is required. However, not any ground source heat pump project can provide enough available drilling area, which also becomes a reason for restricting the development of ground source heat pumps in cities with high building density, so that a pipe burying mode with larger heat exchange amount needs to be considered or drilling holes need to be arranged in other spaces.

The modes of pile foundation pipe burying include a series double U type (W type), a single U type, a parallel double U type, a parallel three U type, a spiral type and the like. The buried pipe is buried in the pile foundation, so that the buried pipe is easily limited by the number and the depth of the buried piles, a certain complementary effect can be achieved for small-sized projects, and if the project scale is large, such as large residential district ground source heat pump projects, the problem that the drilling area is insufficient can not be fundamentally solved.
