Submarine cable trestle suitable for abrupt slope landing and construction method thereof
The invention relates to a submarine cable trestle suitable for abrupt slope landing and a construction method of the submarine cable trestle, and belongs to the technical field of optical cable laying. The submarine cable trestle comprises a landing trestle body which is arranged to be attached to a slope from a seabed surface and extends to the top surface of the slope, and one end, located on the top surface of the slope, of the landing trestle body communicates with a cable trench; the bottom of the landing trestle is sequentially connected with a plurality of anchoring anchor rods embedded in the slope from top to bottom, the end, located on the seabed surface, of the landing trestle is in butt joint with a riprap protection layer, a plurality of filling sandbags are arranged at the bottom end of the riprap protection layer, and armored cables are embedded in the filling sandbags. And the end part of the armored cable extends along the length direction of the landing trestle and then is butted with the cable trench. According to the method, ditching and laying on hard rock are avoided, the construction cost is reasonably reduced, meanwhile, overhaul and construction of a cable climbing section trestle are avoided, and construction operation of a suspended section is achieved by fully utilizing the time of tide rising and falling.
本发明涉及一种适用于陡坡登陆的海缆栈桥及其施工方法，属于光缆布设技术领域，包括从海床面开始贴合斜坡设置且延伸至斜坡顶面的登陆栈桥，所述登陆栈桥位于斜坡顶面的一端连通有电缆沟，所述登陆栈桥底部从上至下依次连接有若干根嵌设在斜坡内部的锚固锚杆，所述登陆栈桥位于海床面的一端对接有抛石保护层，所述抛石保护层底端设置有若干填充沙袋，若干所述填充沙袋内部埋设有铠装电缆，且铠装电缆端部沿登陆栈桥长度方向延伸后与电缆沟对接。本发明避免了在硬质岩上开沟敷设，合理降低了施工成本，同时避免了电缆爬升段栈桥的大修大建，充分利用张退潮的时间实现了悬空段的施工作业。
