Cast-in-place pile penetrating through super-large karst cave and construction method thereof
The invention relates to a cast-in-place pile capable of penetrating through a super-large karst cave and a construction method of the cast-in-place pile, and belongs to the technical field of pile foundations in civil engineering. Comprising a combined pile casing and a reinforcement cage arranged in the combined pile casing, and the combined pile casing and the reinforcement cage are welded into a whole through a positioning clamp. The problems of stability and bearing capacity of the pile body due to the fact that the free section of the pile body in the ultra-large karst cave area is not restrained and protected by the soil body are solved.
本发明涉及一种能够穿越超大溶洞的灌注桩及其施工方法，属于土木工程中桩基础技术领域。包括组合护筒及设于组合护筒内的钢筋笼，组合护筒与钢筋笼通过定位卡焊接为一体。本发明解决了超大溶洞区内桩身临空段不受土体约束和保护而导致的桩体稳定性和承载力的问题。
