Anti-pulling connecting pile structure for foundation slab and construction method of anti-pulling connecting pile structure
The invention discloses an anti-pulling connecting pile structure for a foundation slab and a construction method. The structure comprises a prefabricated hollow pipe pile (4) and a threaded steel pipe (2), wherein the upper end of the prefabricated hollow pipe pile (4) is fixedly connected with a reinforced concrete foundation (6) and serves as a main anti-pulling component, and the threaded steel pipe (2) and the prefabricated hollow pipe pile (4) are kept in a concentric state and installed in a hole. The rhombic anchoring mechanisms (3) are uniformly and continuously arranged along the threaded steel pipe, and each rhombic anchoring mechanism (3) comprises a connecting sleeve (301) provided with an inner hole in sliding connection with the threaded steel pipe (2), a wall supporting connecting rod (302) and a force applying plate (303) which is rotationally connected with the extending end of the wall supporting connecting rod (302), keeps in contact with the inner wall and is used for providing supporting force; the upper end sealing end plate (8) is arranged at the upper end of the threaded steel pipe (2) in a sleeving manner and is fixed at the top of the prefabricated hollow pipe pile (4); and gaps in the prefabricated hollow pipe piles (4) are filled with the concrete.
本发明公开了一种用于基础底板的抗拔连接桩结构及施工方法，结构包括：上端与钢筋混凝土基础(6)固定连接的作为主要抗拔构件的预制空心管桩(4)、与所述预制空心管桩(4)保持同心状态并装入孔内的螺纹钢管(2)；菱形锚固机构(3)，其沿沿螺纹钢管均匀连续布置，所述菱形锚固机构(3)包括设有与螺纹钢管(2)滑动连接内孔的连接套筒(301)、撑壁连杆(302)，与撑壁连杆(302)的伸出端转动连接并与内壁保持接触的用于提供支撑力的施力板(303)；套设于螺纹钢管(2)上端并固定于预制空心管桩(4)顶部的上端封头端板(8)；填充于预制空心管桩(4)内的空隙的混凝土。
