Large-diameter pile foundation steel casing perpendicularity monitoring and correcting device and correcting method
The invention relates to a large-diameter pile foundation steel casing perpendicularity monitoring and correcting device and a correcting method. The device comprises a steel casing alignment line, a computer terminal, a steel casing, a steel pulley, a hydraulic jack, a reaction frame and a laser level meter, the laser level meter emits a vertical laser line, the steel casing alignment line is arranged on the peripheral side surface of the steel casing, the two steel casing alignment lines are arranged in the axial direction of the steel casing and are perpendicular to each other; four counter-force frames are fixed to four diagonal points of the steel casing respectively, scales are arranged on a piston rod of the hydraulic jack, the piston is arranged in the radial direction of the steel casing and installed on the counter-force frames, and the rigid pulley is installed at the tail end of the piston and abuts against the periphery of the steel casing; the steel casing alignment line, the center of the steel pulley and a plumb bob laser line of the laser level meter are positioned on the same vertical plane; when the steel casing alignment line deviates, a distance is formed between the plumb bob laser line of the laser level meter and the steel casing alignment line, and the computer terminal controls the four jacks to perform telescopic displacement so as to adjust the perpendicularity of the steel casing.
本发明涉及一种大直径桩基钢护筒垂直度监测和纠正装置及纠正方法，包括钢护筒照准线、电脑终端、钢护筒、刚滑轮、液压千斤顶、反力架、激光水平仪，激光水平仪发射铅垂激光线，钢护筒照准线设置在钢护筒外周侧面，钢护筒照准线沿钢护筒轴向设置两条且互相垂直；反力架设置四个，分别固定在钢护筒的四个对角点上，液压千斤顶的活塞杆上设置有刻度，活塞沿钢护筒径向设置并安装在反力架上，刚滑轮安装在活塞该末端并抵靠钢护筒外周；钢护筒照准线、刚滑轮的中心和激光水平仪的铅锤激光线位于同一铅垂面上；钢护筒照准线发生偏移时，激光水平仪的铅锤激光线与钢护筒照准线产生间距，电脑终端控制四个千斤顶进行伸缩位移，调整钢护筒的垂直度。
