Underwater hard rock excavation method based on fixed drilling machine
The invention relates to the technical field of channel dredging engineering construction, and discloses an underwater hard rock excavation method based on a fixed drilling machine, which comprises the following steps: S100, construction preparation; s200, the reef explosion ship is parked; s300, positioning piles are put down, and the ship body is fixed to the water surface; step S400, carrying out underwater drilling; s500, the positioning pile is lifted; s600, the ship is moved, and all drilling work of the same layer in the construction area is completed; step S700, carrying out underwater hydraulic crushing; s800, hard rock excavation is carried out; and S900, construction is finished. When the method is used for underwater hard rock excavation, underwater shock waves generated by underwater hydraulic crushing construction are very small, damage to aquatic creatures, underwater pipelines or underwater (building) structures in a construction area and around the construction area is avoided, and the requirement of modern green construction is met.
本发明涉及航道疏浚工程施工技术领域，且公开了一种基于固定式钻机的水下硬岩开挖方法，步骤S100、施工准备；步骤S200、炸礁船驻位；步骤S300、下放定位桩，将船身固定在水面上；步骤S400、水下钻孔；步骤S500、升起定位桩；步骤S600、移船，将施工区域内的同一分层的所有钻孔工作完成；步骤S700、水下液压破碎；步骤S800、硬岩开挖，步骤S900、施工结束；本发明的方法进行水下硬岩开挖时，水下液压破碎施工产生的水下冲击波微乎其微，不会对施工区域内及周边的水生物、水下管线或水下(建)构筑物造成伤害，满足现代绿色施工的要求。
