A heating system combining foundation pit support structure and building structure and its construction method

Abstract

The invention discloses a geothermal heating system combined with a foundation pit support structure and a building structure, comprising a deep water layer heating unit, a pile interlayer heating unit, a building layer heating unit and a circulation pipeline unit, a deep water layer heating unit, and a pile interlayer heating unit Both the unit and the heating unit on the building floor are connected to the steam engine room through the circulation pipe unit; the heat exchange efficiency is high, the heating pipes are arranged in the building pile foundation, and the heating pipes are arranged in the foundation pit support structure, which increases the heat exchange area and changes the The heating mode changes from laminar flow to floc flow, which improves the heat transfer efficiency of the heat transfer liquid; the resource utilization rate is high, and the temporary foundation pit support structure is used for heating without the need for separate drilling and embedding, which improves the Resource utilization rate; high construction efficiency, the number and shape of the pipe body are designed, occupy less construction space, have little impact on the building, heating pipes do not need to be drilled and buried separately, and have little disturbance to the building foundation.

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
