Construction method for detecting underwater pipeline using V-shaped probe groove
The invention discloses a construction method for detecting an underwater pipeline using a V-shaped probe groove. The method is characterized in that the V-shaped probe groove with a certain width is excavated in an area where pipelines are possibly distributed by using a sand pump dredger to detect the underwater pipeline, the excavation section of the V-shaped probe groove is V-shaped, the minimum excavation volume can be ensured, and the designed elevation of the probe groove is 1-2m higher than the designed elevation of dredging construction; during excavation of the probe groove, a diver carries out underwater detection on the probe groove layer by layer, and if the pipeline is detected, the specific position and the elevation of the pipeline are accurately measured so as to carry out next-step treatment; and if the pipeline is not detected, it is proved that no pipeline exists above the dredging design elevation, dredging construction is not affected, and dredging equipment can be arranged for construction. The construction method is not affected by an external environment, the material and size of the pipeline and the burying depth of the pipeline, the detection result precision is high, the quality and efficiency improvement effect is remarkable, the influence of the underwater pipeline on dredging construction is effectively eliminated, and the ship construction safety is guaranteed.
本发明公开了一种利用“V形探槽”探测水底管线的施工方法，该方法在可能分布管线的区域利用抽砂船开挖具有一定宽度的“V”形探槽探测水底管线，“V”形探槽的开挖断面呈“V”形，可保证开挖量最小，探槽设计标高比疏浚施工设计标高低1‑2m；探槽开挖期间由潜水员对探槽逐层进行水下探摸，如探摸到管线，则对其具体位置及标高进行精确测量，以便进行下一步处理；如未探摸到管线，则证明疏浚设计标高以上无管线，对疏浚施工无影响，可安排疏浚设备进行施工。本发明施工方法不受外界环境的影响、不受管线材质和尺寸的影响、不受管线埋设深度影响、探测结果精度高、提质增效效果显著，有效排除了水底管线对疏浚施工的影响，保障了船舶施工安全。
