Submarine cable landing construction method for penetrating through hard rock based on trenchless directional drilling
The invention relates to a submarine cable landing construction method for penetrating through a hard rock based on trenchless directional drilling, which belongs to the technical field of optical cable laying and comprises the following steps of: designing a preset track which downwards forms a certain angle with a vertical plane from a high position and penetrates through a hard rock slope surface; controlling a directional drilling machine to drill a guide hole along the preset track; a drill rod of the directional drilling machine is controlled to drag back along a preset track, the guide hole is expanded, and finally a guide final hole is formed; an anchoring well for construction operation and a cable trench communicated with the anchoring well are excavated in a proper position, and an anchoring device is installed in the anchoring well; and a pulling rope of the armored submarine cable passes through the guiding end hole to the shore. According to the method, ditching and laying on hard rock are avoided, the construction cost is reasonably reduced, meanwhile, a trestle is prevented from being erected on an abrupt slope, the landscape influence on a rock bank reef is reduced, and the influence of scouring and corrosion on a cable structure is avoided.
本发明涉及一种基于非开挖定向钻穿越硬质岩的海缆登陆施工方法，属于光缆布设技术领域，包括下列步骤：设计自高处向下与竖直平面之间呈一定角度且贯穿硬质岩坡面的预设轨迹；控制定向钻机沿所述预设轨迹钻取导向孔；控制定向钻机的钻杆沿预设轨迹回拖，对导向孔进行扩孔，最后形成导向终孔；在合适的位置开挖施工作业的锚固井以及与所述锚固井连通的电缆沟，并在锚固井内部安装锚固装置；将铠装海缆的牵引绳从导向终孔中穿过至岸上。本发明避免了在硬质岩上开沟敷设，合理的降低了施工成本，同时避免了在陡坡上搭设栈桥，减少了对岩石岸礁的景观影响，避免了冲刷、腐蚀对电缆构筑物的影响。
