Hot pile structure, composite foundation and composite foundation construction method
The invention relates to a hot pile structure which comprises a supporting pipe pile used for being arranged in a foundation and a heat exchange pipe section arranged in the supporting pipe pile, and a heat exchange working medium is arranged in the heat exchange pipe section. And the heat dissipation pipe section is used for being arranged outside the foundation and communicates with the heat exchange pipe section. Thus, through mutual cooperation of the heat exchange pipe sections, the heat dissipation pipe sections and the supporting pipe piles, on the first hand, the synergistic effect of cooling and foundation strengthening is achieved, long-term stability of road engineering is guaranteed, and through the supporting and protecting effects of the supporting pipe piles, the risk that internal heat exchange working media leak and lose efficacy due to the fact that the heat exchange pipe sections are damaged due to stress can be avoided; and on the second aspect, through a cold conduction loop formed between the heat dissipation pipe section and the heat exchange pipe section, natural cold energy of the permafrost region is fully utilized to conduct temperature control on the foundation, cooling refrigeration is conducted on the permafrost soft foundation based on the passive refrigeration technology, and the method is environmentally friendly, low in carbon and capable of saving energy. The invention further discloses a composite foundation and a composite foundation construction method.
本发明涉及一种热桩结构，包括：用于设置在地基中的支撑管桩，设于支撑管桩中的换热管段，换热管段内设有换热工质；用于设置在地基之外的散热管段，散热管段连通换热管段。如此，通过换热管段、散热管段和支撑管桩的相互配合，在第一方面，实现了冷却和强化地基的协同作用，保障道路工程的长期稳定，并且通过支撑管桩的支撑和保护作用，可以避免换热管段因受力损坏而导致的内部换热工质泄露失效的风险；在第二方面，通过散热管段、换热管段之间形成的导冷回路，充分利用冻土区的自然冷能为地基进行温度控制，以基于无源制冷技术对多年冻土软弱地基进行冷却制冷，绿色环保，低碳节能。本申请还公开一种复合地基及复合地基施工方法。
