Energy pile and pile burying method thereof
The invention relates to an energy pile and a pile burying method thereof.The energy pile comprises a PHC pipe pile, a high-heat-conduction pervious concrete pile core poured in the pipe pile, a steel reinforcement framework buried in the pile core and a heat exchange pipe, and a plurality of through holes extending in the radial direction are evenly distributed in the lower portion of the PHC pipe pile in the circumferential direction; the steel reinforcement framework is a cylindrical steel reinforcement mesh and is coaxial with the PHC pipe pile, and the heat exchange pipe is fixedly arranged on the inner side of the steel reinforcement mesh. The invention further relates to a pile burying method using the energy pile. The high-heat-conduction pervious concrete pile core is restrained in the PHC pipe pile, the PHC pipe pile plays a main bearing role, the problem that the high-heat-conduction pervious concrete is cracked and damaged under the high-bearing condition is solved, meanwhile, the multiple through holes extending in the radial direction are evenly distributed in the lower portion of the PHC pipe pile in the circumferential direction, after pile burying, the through holes are located below the underground water level, and the through holes are located below the underground water level. Underground water can conveniently penetrate through the PHC pipe pile to directly exchange energy with the high-heat-conduction pervious concrete, the aluminum annular fins and the heat exchange pipe, and the heat conduction efficiency is greatly improved.
本发明涉及一种能源桩及其埋桩方法，其中，能源桩，包括PHC管桩、浇筑在所述管桩内的高导热透水混凝土桩芯、埋设在桩芯中的钢筋骨架以及换热管，所述PHC管桩的下部沿周向均布多个径向延伸的通孔，所述钢筋骨架为筒状的钢筋网且与所述PHC管桩同轴线布置，所述换热管固设于钢筋网内侧；还涉及利用上述能源桩的埋桩方法。本发明的高导热透水混凝土桩芯被约束在PHC管桩内，PHC管桩起到主要承重作用，防止了高承载条件下，高导热透水混凝土崩裂破坏的问题，同时，PHC管桩下部沿周向均布多个径向延伸的通孔，使得埋桩之后，通孔位于地下水位以下，方便地下水穿过PHC管桩直接与高导热透水混凝土、铝制环形翅片以及换热管进行能量交换，导热效率大幅度提高。
