Jacket swirling pile foundation structure and construction method thereof
The invention belongs to the technical field of foundation structures, and discloses a jacket swirling pile foundation structure and a construction method thereof. The jacket swirling pile foundationstructure comprises a jacket formed by connecting main legs and supporting structures. A skirt sleeve is welded to the outer side of the bottom of each main leg, and the jacket is connected with swirling piles through the skirt sleeves; the swirling piles comprise central piles, stiffening rib plates and swirling bearing blades, the stiffening rib plates are arranged at the tops of the central piles, and the swirling bearing blades are arranged at different heights of the central piles according to the soil conditions of an in position site; after the swirling piles are inserted into the skirtsleeves, the swirling piles are in grouting connection with the skirt sleeves through the stiffening rib plates; an anti-sinking structure is arranged at the bottom of the jacket; and during the construction, an integral structure formed by connecting the jacket, the skirt sleeves and the anti-sinking structure is sunk first, and the swirling piles are inserted into a soil body through the skirtsleeves, and pile driving equipment is used for pile driving of the swirling piles; and finally, grouting is used for completing the connection between the swirling piles and the jacket. According tothe jacket swirling pile foundation structure and the construction method thereof, the purposes of saving materials, improving the bearing capacity, reducing the construction time and improving the construction efficiency are achieved.
本发明属于基础结构技术领域，公开了一种导管架打旋桩基础结构及其施工方法，包括由主腿和支撑结构连接构成的导管架，每个主腿底部外侧焊接有裙装套筒，导管架通过裙装套筒连接打旋桩；打旋桩包括中心桩、加劲肋板和打旋承载叶片，加劲肋板设置在中心桩顶部，打旋承载叶片根据就位场地土质条件布置在中心桩的不同高度；打旋桩插入裙装套筒后，通过加劲肋板与裙装套筒灌浆连接；导管架底部设置有防沉结构；施工时，先沉放导管架、裙装套筒和防沉结构连接而成的整体结构，将打旋桩通过裙桩套筒插入土体，并采用打桩设备对打旋桩进行打桩；最后灌浆完成打旋桩与导管架的连接。本发明可以达到节约材料，提高承载力，减少施工时间，提高施工效率的目的。
