External heat exchange tube lower expansion U-shaped energy pile and construction method thereof
The invention relates to a U-shaped energy pile with an external heat exchange tube and a lower expansion body and a construction method of the U-shaped energy pile. The U-shaped energy pile comprises a prefabricated concrete pile body, the U-shaped heat exchange tube, high-thermal-conductivity pervious concrete, crescent aluminum fins and a pile shoe at the bottom of the pile. The U-shaped heat exchange pipe is fixed outside the prefabricated concrete pile body, the high-thermal-conductivity pervious concrete is poured outside the prefabricated concrete pile body, the crescent aluminum fins are arranged outside the U-shaped heat exchange pipe, the pile shoe is arranged at the bottom of the prefabricated concrete pile body, and the U-shaped heat exchange pipe is fixed outside the prefabricated concrete pile body. The lower portion of the high-thermal-conductivity pervious concrete is subjected to mechanical reaming to form a lower expanded body and then poured. Compared with the prior art, the structure is simple, construction is convenient, design is reasonable, production is convenient, the performance of high-thermal-conductivity pervious concrete can be achieved, meanwhile, the bearing capacity of a pile body is improved, the stability is excellent, and the advantages of an energy pile and an expansion pile are integrated.
本发明涉及一种外设换热管下部扩体U型能源桩及其施工方法，U型能源桩包括：预制混凝土桩体、U型换热管、高导热性透水混凝土、铝制月牙形翅片、桩底的桩靴；所述U型换热管固定于所述预制混凝土桩体外，所述高导热性透水混凝土浇筑于所述预制混凝土桩体外，所述铝制月牙形翅片设于所述U型换热管外，所述桩靴设于所述预制混凝土桩体的底部，所述高导热性透水混凝土下部采用机械扩孔形成下部扩体后浇筑。与现有技术相比，本发明结构简单，施工方便，设计合理，便于生产，能够实现高导热性透水混凝土的性能的同时也提高了桩体的承载力，具有优良的稳定性，融合能源桩和扩体桩各自的优点。
