Collimation pile double-pile-casing positioning structure, double-pile-casing device, collimation pile and construction method
The invention relates to a collimation pile double-pile-casing positioning structure, a double-pile-casing device, a collimation pile and a construction method. The invention relates to the technicalfield of building foundation collimation pile construction. The collimation pile double-pile-casing positioning structure comprises a plurality of layers of positioning assemblies which are evenly distributed at intervals in the axial direction of an outer pile casing. Each layer of positioning assembly comprises a plurality of positioning rods vertically inserted into through holes formed in thecylinder wall of the outer pile casing and adjusting pieces connected with the positioning rods and used for adjusting the depth of the positioning rods inserted into the through holes. The multiple positioning rods are evenly distributed in the circumferential direction of the outer pile casing at intervals, one ends of the positioning rods abut against the outer wall of the inner pile casing, and the other ends of the positioning rods extend out of the outer pile casing; the double-pile-casing device comprises the collimation pile double-pile-casing positioning structure. The collimation pile comprises the double-pile-casing device. The collimation pile is adopted in the construction method. According to the application, the problems of poor coaxiality and verticality and uneven stress of the double casings can be improved, and the technical effect of improving the coaxiality and verticality of the inner casing and the outer casing can be achieved.
本申请涉及一种准直桩双护筒定位结构、双护筒装置、准直桩及施工方法，涉及建筑基础准直桩施工技术领域，其准直桩双护筒定位结构包括若干层沿外护筒的轴向间隔均布的定位组件，每层定位组件包括若干个垂直插接在外护筒的筒壁上设有的通孔内的定位杆和与定位杆连接且用于调节定位杆插入通孔内的深度的调节件，若干个定位杆沿外护筒的周向间隔均布，定位杆的一端与内护筒的外壁顶接，定位杆的另一端伸出外护筒；其双护筒装置包括上述准直桩双护筒定位结构；其准直桩包括上述双护筒装置；其施工方法采用上述准直桩。本申请能够改善双护筒的同轴度和垂直度较差、受力不均匀的问题，能够达到提高内外护筒同轴度和垂直度的技术效果。
