Method for replacing bridge ultra-low clearance embedded anchor type support
The invention relates to a bridge ultra-low clearance embedded anchor type support replacing method, and belongs to the field of bridge supports.The bridge ultra-low clearance embedded anchor type support replacing method comprises the steps that firstly, a new support structure is optimized, a new anchoring assembly is optimized, an overwater platform is erected, a bridge is jacked synchronously, and all supports fall in the air through double control over jacking force and jacking amount and graded jacking; secondly, the old support is dismantled, a temporary support is arranged, after the old support is dismantled, the hole position of a new support bolt hole is measured, then drilling is conducted, the new support and a new anchoring assembly are installed, bolts on the new support are tightened, and finally a dust cover is installed; by means of the plane right-angle coring drilling machine, a bridge can be drilled in a water area through an overwater platform under the ultra-low clearance, the drilling efficiency is improved, the replacement efficiency of a new support and an old support is improved, and the situation that a conventional coring drilling machine cannot be suitable for the use condition under the ultra-low clearance even if the height of the conventional coring drilling machine is reduced through modification is avoided.
本申请涉及一种桥梁超低净空嵌锚式支座更换方法，属于桥梁支座领域，桥梁超低净空嵌锚式支座更换方法，包括首先将新支座结构优化，新锚固组件优化，搭设水上平台，桥梁同步顶升，通过顶升力和顶升量双控，分级顶升使支座全部落空，然后拆除旧支座并设置临时支撑，旧支座拆除后，测量新支座螺栓孔的孔位，然后钻孔，安装新支座及新锚固组件，拧紧新支座上的螺栓，最后安装防尘罩；本申请可以通过平面直角取芯钻机，可使在超低净空下通过水上平台在水域上对桥梁钻孔，提高了钻孔效率，提高了新旧支座更换效率，避免了常规取芯钻孔机即使通过改制来降低其自身高度，也无法适用于如此超低净空下的使用条件。
