Curve section large-curvature gravel foundation bed and laying method thereof
The invention relates to the technical field of subsea tunnel gravel foundation bed leveling, in particular to a curve section large-curvature gravel foundation bed and a laying method thereof.The curve section large-curvature gravel foundation bed comprises a long ridge area close to the head end of a to-be-installed pipe joint and a short ridge area close to the to-be-installed pipe joint, and the long ridge area comprises a plurality of gravel ridges arranged in parallel; each gravel ridge is parallel to the head end of a to-be-installed pipe joint, the last gravel ridge and the tail end of the gravel foundation bed form the short ridge area, a short gravel ridge is arranged in the short ridge area, the length of the short gravel ridge is smaller than that of the gravel ridge, the short gravel ridge is parallel to the head end of the to-be-installed pipe joint, and the length of the short gravel ridge is smaller than that of the gravel ridge. The elevations of the centers of all the ridges are ensured to be the same, elevation deviation and accumulated deviation do not exist, and the gravel foundation bed ridge body design modes are enriched; the gravel ridges are arranged in parallel in a staggered mode, the ship position arrangement frequency is not increased on the premise that the gravel foundation bed can completely bear the curve pipe joints, oblique movement of the riprap pipes of the leveling ship can be avoided, and the laying difficulty is lowered.
本发明涉及海底隧道碎石基床整平技术领域，尤其涉及一种曲线段大曲率碎石基床及其铺设方法，包括：靠近待安装管节首端的长垄区和靠近待安装管节的短垄区，所述长垄区包括多条平行设置的碎石垄，且每条所述碎石垄平行于待安装管节首端，最后一条所述碎石垄与所述碎石基床的尾端形成所述短垄区，所述短垄区内设置有短碎石垄，所述短碎石垄的长度小于所述碎石垄的长度，且所述短碎石垄平行于所述待安装管节首端，确保每条垄中心的高程均相同，不存在高程偏差及累计偏差，丰富了碎石基床垄体设计方式；碎石垄平行错位布设，保证碎石基床可以将曲线管节完全承托住的前提下，又不增加船位布置次数，而且可避免整平船抛石管斜线运动，降低铺设难度。
