Prestress anchor bolt tensioning construction process
The invention discloses a prestress anchor bolt tensioning construction process. The construction process comprises the following steps: drilling, corrugated pipe leveling, mud jacking and anchorage device installation. The drilling step comprises: a base hole is formed in the side face of a road through an electric drill, the base hole is perpendicular to the pavement, a lower anchor backing plate is placed in the bottom of the base hole, a corrugated pipe is inserted into the base hole, and the bottom of the corrugated pipe is in threaded connection with the lower anchor backing plate; and the step of leveling the corrugated pipe comprises: fixing the upper part of the corrugated pipe by using a leveling mechanism, fixing and limiting the corrugated pipe by using a limiting plate throughthe leveling mechanism until the corrugated pipe is vertical to the pavement, pouring concrete slurry into the base hole, and controlling the duration time of the concrete slurry from mixing to the tank hole to be within 30 minutes. The step of leveling is added in the installation process of the corrugated pipe and the base hole, and the concrete slurry is poured into the base hole after the corrugated pipe is leveled, so that the corrugated pipe can be perpendicularly fixed to the pavement, the fixing process is firmer, and the corrugated pipe is not prone to shaking after being extruded bythe slurry.
本发明公开了一种预应力锚栓张拉施工工艺，该施工工艺包括以下步骤：钻孔‑波纹管找平‑压浆‑锚具安装；步骤一：钻孔，采用电钻在道路的侧面开设基孔，基孔垂直于路面，在基孔的底部放入下锚垫板，并将波纹管插入到基孔的内部，波纹管的底部与下锚垫板螺纹连接；步骤二：波纹管找平，利用找平机构固定波纹管的上部，找平机构利用限位板对波纹管进行固定限位，直至波纹管与路面垂直，向基孔的内部倒入混凝土浆料，混凝土浆料自调制至罐孔的延续时间在30min以内。通过在波纹管与基孔安装过程中增加找平的步骤，波纹管经过找平后才向基孔的内部灌入混凝土浆料，使得波纹管能与路面垂直固定，固定过程中更加牢固，不易在受到浆料挤压后发生晃动。
