Hollow interlayer concrete filled steel tube stiffening hybrid energy pile structure and construction method
The invention relates to the field of ground source heat pumps, in particular to a hollow interlayer concrete-filled steel tube stiffening hybrid energy pile structure and a construction method.The pile structure comprises a core hollow interlayer concrete-filled steel tube member which comprises an inner steel tube and an outer steel tube which are concentrically arranged, and core concrete is poured between the inner steel tube and the outer steel tube; the externally-wrapped reinforced concrete member comprises a reinforcement cage and externally-wrapped concrete, the reinforcement cage is bound to the outer side of the outer steel pipe, a geotextile bag is arranged on the periphery of the reinforcement cage, and the externally-wrapped concrete is formed by pouring the geotextile bag; the heat pump exchange pipe comprises a heat pump exchange spiral pipe and a heat pump exchange straight pipe which are communicated with each other, the heat pump exchange spiral pipe is arranged around the reinforcement cage, and the heat pump exchange straight pipe is laid in the hollow area of the inner steel pipe. The hollow interlayer concrete-filled steel tube stiffening mixed pile technology and the ground source heat pump technology are combined, the additionally-arranged externally-wrapped reinforced concrete member can provide high bearing capacity, and the corrosion resistance of the core hollow interlayer concrete-filled steel tube member and the heat pump exchange system is improved.
本发明涉及地源热泵领域，具体涉及一种中空夹层钢管混凝土加劲混合能源桩结构及施工方法，桩结构包括：核心中空夹层钢管混凝土构件，包括同心设置的内钢管和外钢管，内钢管和外钢管之间浇筑有核心混凝土；外包钢筋混凝土构件，包括钢筋笼和外包混凝土，钢筋笼绑扎于外钢管外侧，钢筋笼外围布设土工织物袋，外包混凝土通过土工织物袋浇筑形成；热泵交换管，包括相互连通的热泵交换螺旋管和热泵交换直管，热泵交换螺旋管围绕钢筋笼设置，热泵交换直管铺设于内钢管的中空区域。本发明结合中空夹层钢管混凝土加劲混合桩技术和地源热泵技术，加设的外包钢筋混凝土构件可以提供较强承载力，提升核心中空夹层钢管混凝土构件和热泵交换系统的抗腐蚀能力。
