Pile foundation pile repairing construction technology under existing pile foundation condition
The invention provides a pile foundation pile repairing construction process under the existing pile foundation condition, which comprises the following steps of: acquiring a coordinate system of original pile foundation construction, and determining pile sinking information of an existing pile foundation; after the precast pile foundation is sunk to a first set position at the position to be repaired, a pile body is pulled out, a detection assembly is arranged at the downward end of the pile body, the peripheral environment of a detection point is obtained through the measuring pipe and the first detection assembly in the measuring pipe in a rotary detection mode, and a geological radar detection record chart is drawn; according to the geological radar detection record chart, whether pile repairing and pile sinking are continued or pile repairing is carried out again is judged; if pile sinking continues, when pile sinking of the prefabricated pile foundation is conducted at a second set position, the measuring pipe and a second detection assembly in the measuring pipe are used for detecting coordinates of the original pile foundation at the second set position and distribution of the original pile foundations on the periphery of the measuring pipe, and a pile sinking scheme for pile foundation repairing is set according to detection data till pile sinking is finished. According to the invention, by arranging the detection unit, obstacle avoidance detection and the like in encryption are realized.
本发明提供了既有桩基条件下的桩基补桩施工工艺，包括以下步骤：获取原有桩基施工的坐标系，确定现有桩基的沉桩信息；于待补桩位置，预制桩基沉桩至第一设定位置后，拔出桩身，在桩身朝下端设置探测组件，通过测量管以及其内的第一探测组件，选用旋转探测的方式，获取探测点外周环境，并绘制地质雷达探测记录图；根据地质雷达探测记录图，判断是否继续进行补桩沉桩或重新补桩；若继续沉桩，则预制桩基沉桩在第二设定位置时，利用测量管以及其内的第二探测组件探测第二设定位置处原有桩基的坐标以及外周的原有桩基分布，并根据探测数据设定补桩桩基的沉桩方案，直至沉桩结束。本发明通过设置探测单元，以实现加密中的避障探测等。
