Bridge pile foundation reaming construction technology
The invention discloses a bridge pile foundation reaming construction technology, and relates to the technical field of bridge pile foundations. A pile casing is embedded in the pre-selected position, a drilling machine rack body enters the site to be in place, a drill bit conducts two times of side-by-side construction, and two side-by-side pile foundation holes are constructed; a percussion bit is adopted for reaming operation, and a reaming bit is connected and installed; the rotating blades rotate through rotation of the pile expanding barrel, the rack body enables the pile expanding barrel to slide downwards to be matched with the rotating blades to take out soil, then the electric push rod is installed at the bottom end of the pile expanding barrel, rotation of the connecting drill bit enables the positioning shell to rotate, and rotation of the positioning shell enables the hole expanding head to rotate for hole expanding. The telescopic plate can slide during operation of the second air cylinder, the hole expanding caliber of the hole expanding head can be adjusted through sliding of the telescopic plate, hole expanding operation is conducted according to work requirements, hole expanding equipment does not need to be switched to conduct hole expanding work independently, and therefore the hole expanding construction efficiency of the bridge pile foundation is improved.
本发明公开了一种桥梁桩基扩孔施工工艺，涉及桥梁桩基技术领域，包括以下步骤；对预选位置进行埋设护筒，钻机机架体进场就位，钻头进行两次并排施工，施工成并排的两个桩基孔；采用冲击钻头进行扩孔操作，将扩孔钻头连接安装；通过扩桩筒的转动从而使旋转叶片转动，机架体使扩桩筒向下滑动配合旋转叶片将土壤取出，再将电动推杆安装支扩桩筒的底端处，连接钻头的转动进而使定位壳转动，定位壳的转动从而是扩孔头转动进行扩孔，二号气缸的运作可以是伸缩板滑动，伸缩板的滑动进而可以调节扩孔头扩孔的口径，根据工作需求进行扩孔操作，不需要切换扩孔设备单独进行扩孔工作，从而提高桥梁桩基扩孔施工效率。
