Coupling type ground source heat pump mixed backfill technology and backfill material
The invention provides a coupling type ground source heat pump mixed backfill technology. The technology comprises the seven steps of construction preparing, drilling hole forming, heat exchange pipe preconstructing, heat exchange pipe installing, drilling hole backfill, horizontal pipe constructing and horizontal pipe filling. The coupling type ground source heat pump mixed backfill material is formed by mixing cement, expansive soil and water. According to the adopted construction method and the backfill material, on one hand, the stability of heat exchange between a heat exchange system and the underground environment can be effectively improved, and the heat exchanging efficiency is improved; on the other hand, the damage and pollution to the geologic structure and the underground water environment from the heat exchange system can be effectively relieved, and environmental adaptability is improved. Meanwhile, the underground positioning safety and stability of a heat exchanger device can be effectively improved, and accordingly the integral running efficiency, the running reliability and the environment-friendliness performance of the heat exchange system are improved.
