Main bridge steel casing composite pile foundation and bridge pile foundation construction technology
The invention provides a main bridge steel casing composite pile foundation and a bridge pile foundation construction technology, and relates to the technical field of building construction. The main bridge steel pile casing composite pile foundation comprises a pile casing body and a reinforcement cage, the pile casing body comprises an insertion pile casing section, a positioning pile casing section, an anti-shearing pile casing section and a bearing platform pile casing section which are sequentially welded and fixed, an insertion section of the insertion pile casing section is provided with a cutting edge, and the insertion pile casing section is used for entering a pile foundation hole through an insertion end; the bearing platform pile casing section comprises an integrated annular cylinder body and a plurality of ribs, the ribs are all located at one end of the annular cylinder body and distributed in the circumferential direction of the annular cylinder body at intervals, positioning grooves are formed in the two side faces, in the circumferential direction of the annular cylinder body, of each rib, and the positioning grooves are used for being matched with the knocking belts in an inserted mode; each rib can incline outwards under external force by taking the end part, connected with the annular cylinder body, of the rib as a fulcrum; the reinforcement cage is used for being inserted into the pile casing body. The pile foundation is low in construction difficulty, high in construction efficiency and high in construction quality.
本申请提供一种主桥钢护筒复合桩基和桥梁桩基施工工艺，涉及建筑施工技术领域。主桥钢护筒复合桩基包括护筒主体和钢筋笼，护筒主体包括依次焊接固定的插入护筒段、定位护筒段、抗剪护筒段和承台护筒段，插入护筒段的插入断设有刃口，插入护筒段用于利用插入端进入桩基孔内；承台护筒段包括一体式的环形筒体和多根肋条，多根肋条均位于环形筒体的一端且在环形筒体的周向上间隔排布，每根肋条在环形筒体的周向上的两个侧面上均设置有定位槽，定位槽用于与敲击带插接配合；每根肋条能够在外力下以肋条的与环形筒体连接的端部为支点向外倾斜；钢筋笼用于插入护筒主体内。该桩基施工难度低，施工效率高，施工质量高。
