Construction method of cylindrical underground enclosure structure
The invention relates to the technical field of building construction, in particular to a construction method of a cylindrical underground enclosure structure. The cylindrical underground enclosure structure comprises an enclosure structure and a main body structure, and the enclosure structure comprises an upper combined pile and a lower combined pile connected to the bottom of the upper combined pile; the flow-state solidified soil filling layer is arranged between the upper combined pile and the main body structure, and the flow-state solidified soil filling layer and the upper combined pile are anchored through enclosing purlin embedded steel bars; the top beam is arranged at the top end of the upper combined pile, and the upper combined pile penetrates through the top beam; the construction method of the cylindrical underground enclosure structure has the beneficial effects that the cylindrical enclosure structure is adopted, water and soil pressure borne by the enclosure structure is converted into circumferential stress, and use of an inner support and an anchor rod is avoided; under the soil-rock binary stratum condition, the upper soil layer and soft rock adopt large-diameter plain concrete piles and combined piles to be meshed to form a wall, and the lower hard rock adopts combined micro piles, so that the large-diameter piles are prevented from being used in the hard rock.
本发明涉及建筑施工技术领域，具体为一种筒形地下围护结构施工方法包括围护结构和主体结构，所述围护结构包括上部组合桩以及连接在上部组合桩底部的下部组合桩；流态固化土灌填层设于上部组合桩与主体结构之间，且流态固化土灌填层和上部组合桩通过围檩植筋锚固；冠梁设于上部组合桩的顶端，且上部组合桩贯穿冠梁；有益效果为：本发明提出的筒形地下围护结构施工方法采用筒形围护结构，将围护结构受到的水土压力转化为环向应力,避免了内支撑和锚杆的使用；土岩双元地层条件下，上部土层及软岩采用大直径素砼桩与组合桩咬合成墙，下部坚硬岩石采用组合微型桩，避免了大直径桩在坚硬岩石中的使用。
