Positioning method for cast-in-place pile adjacent to underground deeply-buried pipeline
The invention relates to a method for positioning a cast-in-place pile adjacent to an underground deeply-buried pipeline, which comprises the following steps of: 1, marking a pile position according to a design drawing, and sloping and excavating a pit hole with the depth of about 1m at the pile position; 2, releasing a pipeline side line; 3, high-pressure water is introduced through a water supply main pipe, a hole is vertically and downwards punched in the side line of the pile position, a flushing pipeline is drawn up and down, and whether the pipeline collides with the underground pipeline or not is checked; if collision occurs, the flushing pipe is pulled out, and punching sounding is repeated after the position is adjusted until the actual sideline of the underground pipeline is found out; pumping accumulated water in the pit into a mud pit for cast-in-place pile construction by using a mud pump; 4, closing the water source, and keeping the water blowing pipe vertically inserted as a field marking point; fifthly, the pile casing is driven into the ground through a pile driving and pulling machine; and sixthly, the pits in the pile positions are backfilled. The method is simple and feasible, professional tools are not needed, the position of the adjacent underground deeply-buried pipeline is accurately detected, and the adjacent deeply-buried pipeline is prevented from being damaged during hole forming or construction of the cast-in-place pile.
本发明涉及一种紧邻地下深埋管线的灌注桩定位方法，步骤一：根据设计图纸标出桩位，在桩位处放坡开挖约1m深的坑洞；步骤二：放出管道边线；步骤三：用供水主管通高压水，在桩位边线上垂直向下冲孔，上下抽动冲水管道，看管道是否与地下管道相碰；如相碰则拔出冲水管，调整位置后重复冲孔触探，直至找出地下管道的实际边线；坑内积水用泥浆泵抽入灌注桩施工用的泥浆池；步骤四：关闭水源，吹水管保持垂直插入作为现场标记点；步骤五：把护筒用打拔桩机打入地下；步骤六：回填桩位处的坑洞。本发明简单可行、不需利用专业工具、准确探明紧邻的地下深埋管线位置灌注桩定位方法，避免灌注桩成孔或施工时损坏紧邻的深埋管线。
