Construction method of bridge pile foundation on highway
The invention discloses a construction method of a bridge pile foundation on a road. Comprising the following steps of staking out in survey, burying a pile casing, preparing slurry, forming holes in a combined mode, treating a melt pile foundation hole, checking the formed holes, installing a guide pipe after the first time of hole cleaning is finished, processing, hoisting and placing a reinforcement cage, cleaning the holes for the second time, pouring underwater concrete, disassembling a hopper and the guide pipe, detecting the formed pile, and grouting after the pile, main reinforcements of the steel reinforcement cage are connected through straight thread sleeves, the cage body is required to be integrally firm and free of deformation, lug reinforcements are arranged on the outer side of the steel reinforcement cage every 2 meters in the longitudinal direction, so that the thickness of a foundation pile net protection layer is guaranteed, connectors of the steel reinforcement cage are staggered, and the number of the connectors in the same section is not larger than 50%. According to the construction method of the bridge pile foundation on the road, collapse can be avoided, and the reinforcement cage is not prone to deformation.
本发明公开了一种公路上桥梁桩基的施工方法，包括以下步骤：测量放样、埋设护筒、泥浆制备、组合方式成孔、溶桩基洞处理、成孔检查、第一次清孔结束后进行导管安装、钢筋笼加工及吊放、第二次清孔、灌注水下混凝土、拆卸料斗及导管、成桩检测、桩后压浆，其中，钢精笼采用分段吊装的方式入孔，钢精笼的主筋采用直螺纹套筒连接，笼体要求整体牢固不变形，在钢筋笼外侧延纵向每2米设置一道耳筋，以保证基桩净保护层厚度，钢筋笼连接头相互错开，同一截面内接头数量不得大于50％。该公路上桥梁桩基的施工方法可以避免坍塌，且钢筋笼不易变形。
