Embodiment Construction
[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0035] In recent years, with the rapid development of my country's economy, the scale of urban infrastructure has gradually increased, the use of underground space has received more and more attention, and the requirements for foundation pit engineering have also become higher and higher. In order to fully meet the functional needs of urban residents for transportation, parking, and commerce, deep foundation pit projects are becoming more and more common. As a very important auxiliary project in the design and construction of foundation pit excavation and support engineering, support piles have a very important impact on the stability and safety of the side wall of the foundation pit. The traditional supporting piles are buried in the soil after the underground construction is completed and the foundation pit is backfilled, and exist ...

The invention discloses a heat exchange system based on deep buried pipe energy support piles and a construction technology, the heat exchange system comprises energy support piles distributed between cast-in-place support piles, each energy support pile comprises a cast-in-place support pile section, a support pile heat exchange well and a deep heat exchange well, the support pile heat exchange well is arranged in the cast-in-place support pile section, the deep heat exchange well is arranged at the bottom of the support pile heat exchange well and communicated with the support pile heat exchange well to form a deep buried pipe channel, an energy pile heat exchange pipe is arranged in the deep buried pipe channel, and a water inlet pipe and a water outlet pipe of the energy pile heat exchange pipe are connected into an indoor heat exchange unit. According to the heat exchange system based on the deep buried pipe energy support piles and the construction technology, secondary development is conducted on a pouring support pile, the pouring support pile is developed into the energy support pile in combination with the energy pile technology, and deep geothermal clean energy is extracted to supply energy to an upper building on the basis that original functions are not affected; the problem of waste caused by discarding of the cast-in-place support pile after the construction of an underground structure is completed is solved.
Description
technical field [0001] The invention relates to the technical field of resource utilization, in particular to a heat exchange system and construction technology based on deep-buried pipe energy support piles. Background technique [0002] With the rapid development of human society, the consumption of energy is also increasing. However, China's current energy structure is still dominated by coal. Coal is a non-renewable energy source, and the burning process will cause serious pollution to the environment. Therefore, the development of New energy is imperative. As a clean and renewable energy source, geothermal energy can greatly reduce building energy consumption. [0003] As a new type of ground source heat pump technology, energy piles have become a main form of geothermal clean energy utilization by virtue of saving floor space, saving additional drilling costs, and large heat transfer. It is an improvement of traditional ground source heat pumps and building pile found...
