Cover-excavation top-down method permanent steel pipe column positioning verticality adjusting device and construction method
The invention discloses a cover-excavation top-down method permanent steel pipe column positioning verticality adjusting system which comprises a tool section, a positioning platform, a positioning mechanism, a cross sight bead plate, a laser positioning instrument and a controller, the upper end of the tool section extends out of a pile hole, the lower end of the tool section is connected with the upper end of a steel pipe of a steel pipe column, and the lower end of the steel pipe is inserted into a cast-in-situ bored pile at the bottom; the positioning platform is rectangular and fixed to the horizontal ground on the periphery of a pile hole, the positioning platform and the pile hole are coaxially arranged, and the lower end of the tool section exceeds the top of the positioning platform. The multiple sets of positioning mechanisms are arranged between the inner edge of the positioning platform and the tool section in the circumferential direction at intervals, and the driving ends of the positioning mechanisms make contact with the outer circumferential face of the tool section. The invention further discloses a construction method for positioning the permanent steel pipe column through the cover-excavation top-down method. The method has the beneficial effects that the information technology and mechanical equipment are connected to achieve automatic adjustment of the positioning perpendicularity, an operator does not need to enter a steel sleeve, the steel pipe column and the pile foundation can be accurately positioned rapidly and conveniently, and automatic adjustment work of the perpendicularity is efficiently completed.
本发明公开了一种盖挖逆作法永久钢管柱定位调垂系统，包括工具节、定位平台、定位机构、十字准星板、激光定位仪和控制器，所述工具节的上端伸出桩孔，工具节的下端与钢管柱的钢管上端相连，钢管下端插入底部的钻孔灌注桩内；所述定位平台为矩形，其固定于桩孔外围的水平地面上，定位平台与桩孔同轴配置，工具节的下端超出定位平台顶部；所述定位机构有多组，周向间隔布置于定位平台内沿与工具节之间，定位机构的驱动端与工具节的外周面接触。本发明还公开了一种盖挖逆作法永久钢管柱定位施工方法。本发明的有益效果为：本发明利用信息技术与机械设备联机实现定位垂直度自动化调整，无需作业人员进入钢套筒，即可快速、方便地将钢管柱与桩基精确定位，并高效完成垂直度自动调整工作。
