Inflatable sleeve device for eliminating lateral resistance of test pile
The inflatable sleeve device comprises a foundation pile reinforcement cage, a ring rib fixing support, a ring rib, an annular thin plate and an annular air bag, one end of the ring rib fixing support is connected to the periphery of the foundation pile reinforcement cage, the other end of the ring rib fixing support is connected to the ring rib, the annular thin plate is connected to the periphery of the ring rib, and the annular air bag is connected to the annular thin plate. The annular thin plate is sleeved with the annular air bag. The device has the beneficial effects that the annular air bag is arranged, in the foundation pile construction stage, the annular air bag is pressurized and inflated to fix the reinforcement cage and prevent the foundation pile from expanding a mold, in the pile testing stage, the annular air bag is deflated and decompressed and taken out, a certain gap is formed between the side wall of the pile and the surrounding soil body, and therefore the side resistance of the test pile and the soil around the pile is eliminated. In addition, the device is simple in structure, convenient to implement, capable of being repeatedly used, good in economical efficiency and real and reliable in result.
本发明公开了一种消除试验桩侧阻的可充气套筒装置，包括基桩钢筋笼、环筋固定支座、环筋、环形薄板、环形气囊，环筋固定支座的一端连接在基桩钢筋笼的外围，环筋固定支座的另一端连接在环筋上，环形薄板连接在环筋外围，环形气囊套在环形薄板外围。本发明有益效果：本发明设置环形气囊，在基桩施工阶段通过给环形气囊加压充气实现钢筋笼的固定及基桩不涨模，在试桩阶段通过环形气囊放气泄压并拿出环形气囊，桩侧壁与周围土体形成一定间隙，从而消除试验桩与桩周土的侧阻。环形气囊取出后可以二次利用，且本装置构造简单、实施方便、可重复利用具有很好的经济性、结果真实可靠。
