According to the seabed stone laying and ramming operation method, articulated chute stone laying equipment and vibrating ramming equipment are arranged on the broadside of a main deck of an engineering ship, an articulated chute of the articulated chute stone laying equipment extends downwards to the seabed, and a vibrating bar of the vibrating ramming equipment extends downwards to the seabed. Three full-revolving propellers are arranged on the stern portion of the engineering ship side by side, two side thrusters are arranged on the bow portion of the engineering ship, under the four-level sea condition, the propelling speed of the full-revolving propeller located in the middle is consistent with the stone laying and ramming operation speed, and the maximum tying thrust Fs of the two side thrusters is not smaller than 20 t; the maximum tying thrust of the full-revolving propellers located on the two sides is not smaller than 60 t, and the output thrust Fa of the bow thruster is smaller than or equal to Fs. The engineering ship travels at a constant speed and performs stone paving and ramming operation at the same time, the operation needs to be stopped only when all stones in a stone storage yard are used up, the continuous operation of offshore stone paving and ramming is truly achieved, and the operation efficiency is greatly improved.

    一种海底铺石及夯平作业方法,工程船的主甲板舷侧设置有溜管铺石设备和振动夯平设备,溜管铺石设备带有的溜管向下延伸至海底,振动夯平设备带有的振动棒向下延伸至海底。工程船艉部并排设置有三个全回转推进器,艏部设置有两个侧推装置,在4级海况条件下,位于中间的全回转推进器的推进速度与铺石夯平作业速度一致,两个侧推装置的最大系住推力Fs不小于20t,位于两侧的全回转推进器的最大系住推力不小于60t,艏侧推装置输出推力Fa≤Fs。本发明工程船一边匀速行驶,一边进行铺石和夯平作业,只需在石料堆场内的石料全部用尽时才需要停止作业,真正实现了海上铺石及夯平的连续作业,极大地提高了作业效率。
