Environment-friendly seabed DCM pile head removing construction technology
The invention belongs to the field of seabed DCM pile head body removing construction processes, and particularly relates to an environment-friendly seabed DCM pile head removing construction process which comprises the following steps that firstly, various construction devices of an overwater breaking excavation platform are overhauled; secondly, the overwater breaking excavation platform is moved to the position above the area to be broken and excavated, and the overwater breaking excavation platform is fixed through a winch anchor cable; 3, selecting a DCM test area to carry out a typical breaking excavation construction test; fourthly, the grab bucket is lowered to the DCM pile head body for breaking excavation; fifthly, the overwater breaking excavation platform is driven out of the first excavation area, multi-beam water depth measurement is conducted on the second excavation area, and a three-dimensional landform graph of the second excavation area is established; sixthly, analyzing the three-dimensional landform graph after breaking excavation, and continuing to construct the undercut area which does not reach the designed elevation according to the fourth to fifth steps; and 7, breaking excavation preparation work of the next area is carried out, and the steps are repeated.
本发明属于海底DCM桩头主体清除施工工艺领域，具体的说是一种环保型海底DCM桩头清除施工工艺，该施工工艺包括以下步骤：第一步：检修水上破除开挖平台的各类施工设备；第二步：将水上破除开挖平台行驶移至待破除开挖区域上方，通过绞锚缆固定水上破除开挖平台；第三步：选取DCM试验区域进行破除开挖典型施工试验；第四步：将抓斗下放至DCM桩头主体处进行破除开挖；第五步：将水上破除开挖平台驶出第一开挖区域，对第二开挖区域进行多波束水深测量，建立第二开挖区域的三维地貌图形；第六步：分析破除开挖后的三维地貌图形，对没有达到设计标高的欠挖区域按照第四至第五步继续施工；第七步：进行下一区域的破除开挖准备工作，以此循环。
