Embodiment Construction

[0026] In Figure 1, the water source heat pump utilizes the low-temperature potential heat energy of the shallow groundwater geothermal resources on the surface. In winter, the heat of the groundwater in the shallow aquifer (2) is extracted through the engineering scrapped precipitation well type water source heat pump tube well (1), and is passed through the surface The exchange pipeline (3) and the ground source heat pump unit (4) supply the building (5) for heating; in summer, the heat of the building (5) is taken out and passed through the surface exchange pipeline (3), the ground source heat pump unit (4) and The discarded dewatering well type water source heat pump tube well (1) is released into the groundwater in the shallow aquifer (2).

[0027] In the embodiment shown in Fig. 2, engineering discarded dewatering well type water source heat pump tube well (1) is a single tube well, and the structure of normal whole well is to be filled with gravel (9 and 10) outside the ...

Abstract

The present invention is water source heat pump pipe well formed through reforming used engineering precipitating well. The engineering precipitating well after completing normal precipitating task is reformed through flushing, water pumping test, water refilling test, measuring water temperature, laying submerged water pump to form water source heat pump pipe well. By means of pumping out water and refilling water and the heat exchange of underground water and the stratum, an opened low temperature water source geothermal circulating system is formed.

Description

Technical field: [0001] The invention relates to the combination of the reprocessing technology of the discarded dewatering wells of construction projects and the technology of water source heat pumps. A multifunctional water source heat pump tube well with water source low temperature geothermal energy circulation heat transfer capability. Background technique: [0002] At present, known engineering dewatering wells mainly refer to tube wells serving engineering dewatering, and their use time limit is limited, generally ending with the completion of the main project or excavation engineering construction. The discarded precipitation wells must be sealed and filled in time, otherwise they will conspire to pollute the groundwater and cause safety hazards (Guan Chao, When will the well eat people, Labor Protection Magazine, 2000 (6): 35), affect the normal construction of other hidden projects, etc. Local governments have also issued relevant policies to report that waste wat...
