Geothermal heating system combining foundation pit supporting structure and building structure and construction method thereof

Abstract

The invention discloses a geothermal heating system combining a foundation pit supporting structure and a building structure. The geothermal heating system combining the foundation pit supporting structure and the building structure comprises a deep water layer heating unit, a pile interlayer heating unit, a building layer heating unit and a circulating pipeline unit, and the deep water layer heating unit, the pile interlayer heating unit and the building layer heating unit are connected with a steam engine room through the circulation pipeline unit. The heat transfer efficiency is high, and heating pipes are laid in a building pile foundation, and the heating pipes are laid in the foundation pit supporting structure, the heat transfer area is increased, a heating mode is changed from laminar flow to flocculation flow, and the heat transfer efficiency of a thermally conductive liquid is improved meanwhile; the resource utilization rate is high, the temporary foundation pit supporting structure is used for heating without the need for separate drilling and burial, and the resource utilization rate is improved; and the construction efficiency is high, the laying number and shape of pipe bodies are designed, the occupied construction space is less, the impact on the building is small, the heating pipes do not need to be drilled and buried separately, and the disturbance to the building foundation is small.

Description

technical field [0001] The invention relates to the technical field of building heating, in particular to a heating system combined with a foundation pit support structure and a building structure and a construction method thereof. Background technique [0002] The ground source heat pump is a high-efficiency, energy-saving and environment-friendly air-conditioning system that uses underground shallow geothermal resources to provide both heating and cooling. Ground source heat pumps can transfer energy from a low-temperature heat source to a high-temperature heat source by inputting a small amount of high-grade energy. In winter, the heat in the soil is "taken" out, and the temperature is raised and supplied to the room for heating; in summer, the heat in the room is "taken out" and released into the soil, and the indoor temperature can be maintained throughout the year. However, at present, the pipelines buried by ground source heat pumps are generally constructed separate...

AI Technical Summary

Problems solved by technology

However, at present, the pipelines buried by ground source heat pumps are generally constructed separately, and will have a certain impact on the building foundation during the construction process, which is not conducive to the safety of the building structure; A commonly used form of support, which is directly left on the ground after the construction of the building foundation is completed, and the resource utilization rate is low

[0003] An energy pile and its system disclosed in Chinese patent literature, the application number is CN201310459205, mainly includes a pile body and a heat exchange tube arranged inside the pile body, the pile body is arranged underground, and the pile body The body is a composite body composed of cement, fly ash and gravel. The heat exchange tube forms a heat conduction path inside the pile body, but it has the following disadvantages: (1) The heat transfer efficiency is low. Many heat exchange pipes are buried in the pile body, but the thermal conductivity of the pile body is limited, so the heating efficiency is not high; (2) The resource utilization rate is low, only the heating pipes are buried in the pile foundation, and the foundation pit support structure is not considered Application in heating; (3) The construction efficiency is low, and too many pipelines are buried in the pile body, which is not conducive to the pile body construction
