Accurate positioning device suitable for permanent and temporary combined steel pipe column and construction method
The invention discloses an accurate positioning device suitable for a permanent and temporary combined steel pipe column, the accurate positioning device comprises a jack working platform, the steel pipe column, a laser emitter, a laser receiving plate and a rib plate, and a steel pipe column positioning use method comprises the following steps: carrying out hole detection on a construction part of the steel pipe column, excavating by using a rotary excavating drill after hole detection, putting the steel pipe column into a steel reinforcement cage, and carrying out hole detection on the steel pipe column; the top of the steel pipe column is adjusted and fixed through an upper jack, a lower jack is connected with a cushion block structure preset on a protection wall in advance in a mortise and tenon mode, then the hydraulic system and the control system adjust the jacks to adjust the lower position of the steel pipe column, and finally the perpendicularity of the steel pipe column is confirmed through a laser emitter. And then the steel reinforcement cage is poured through the guide pipe, concrete is poured to the position about 3 m above the bottom of the steel pipe column, and the lower jack is hoisted for the next steel pipe column to continue to use. According to the method, the permanent and temporary combined steel pipe column can be effectively and accurately positioned in cover-excavation method construction, and the construction quality of the steel pipe column is guaranteed.
本发明公开了一种适用于永临结合钢管柱的精确定位装置，精确定位装置包括千斤顶工作平台、钢管柱、激光发射仪、激光接收板和肋板，钢管柱定位使用方法为：在钢管柱施工部位进行探孔，探孔后使用旋挖钻开挖，将钢管柱放入钢筋笼中，顶部通过上部千斤顶调节固定，下部千斤顶通过榫卯式方式与提前预设在护壁上的垫块结构连接，再通过液压系统及控制系统通过对千斤顶的调节以调整钢管柱下部位置，最后通过激光发射仪确认钢管柱的垂直度，再通过导管对钢筋笼进行浇筑，混凝土浇筑至钢管柱底部以上3m左右，将下部千斤顶吊起，以供下根钢管柱继续使用。本发明可以有效的对盖挖法施工中永临结合钢管柱进行精确定位，保证钢管柱的施工质量。
