Rock breaking construction method of underwater deep foundation trench
The invention relates to a rock breaking construction method of an underwater deep foundation trench. The method comprises the following steps that the depth and sound velocity profile information ofa dredging construction area is determined; a construction ship accurately positions the dredging construction area through a positioning system; the construction ship excavates the soil covering layer of the dredging construction area; the rock distribution condition of the dredging construction area is determined through secondary measurement; rock drilling points and the number of times of rockdrilling are set, and rock breaking construction is conducted through a rock breaking hammer; broken rock is removed; and the dredging construction area is measured, and if the measurement result meets the acceptance standard, construction of the dredging construction area is finished. According to the method, rock breaking treatment can be conducted on rock of an underwater deep trench foundation bed, the adaptability is high, the method can be applied to treatment construction of rock strata with various strengths and large water depth, the implementation precision is high, the implementation process does not relate to use of detonators and explosives, the influence on the surrounding environment is small, environmental protection is achieved, the operation process is safe and reliable,and the popularization value is extremely high.
本发明涉及一种水下深基槽破岩施工方法，包括以下步骤：确定疏浚施工区域的深度和声速剖面信息；施工船舶通过定位系统对疏浚施工区域进行精准定位；施工船舶对疏浚施工区域的泥土覆盖层进行开挖；通过二次测量确定疏浚施工区域的岩石分布情况；设定凿岩点和凿岩次数，通过破岩锤进行破岩施工；对破碎的岩石进行清除；对疏浚施工区域进行测量，若测量结果满足验收标准，则结束该疏浚施工区域的施工。该方法能够对水下深槽基床的岩石进行破岩处理，适应性强可应用于水深较深的各种强度的岩层处理施工，实施精度高，且实施过程不涉及雷管、炸药的使用，对周边环境影响小，绿色环保，操作过程安全可靠，极具推广价值。
