Underwater foundation bed tamping construction method
The invention relates to an underwater foundation bed tamping construction method which is characterized in that the bottom of a tamping machine slides on a track of a tamping work ship, and a suspension arm of the tamping machine is a variable-amplitude suspension arm; the tamping work ship serves as the center, regional framing is conducted on the foundation bed according to the length of a rail and the amplitude stroke of a suspension arm, and after the position of the tamping work ship is determined, the center of a rammer is aligned with a framing region angular point to serve as a tamping starting point; starting the tamping machine, lifting the hammers to tamp the first hammer, tamping the second hammer after the tamping machine slides to the radius stroke of the tamping hammer, and the like, tamping while walking, tamping to the tail end of the array hammer by hammer, and then stopping walking and tamping; then a rammer is placed on the foundation bed, after the suspension arm is free of the rammer load, the amplitude of the suspension arm is changed to the next level, and ramming is conducted on the next array till the array reaches the other end; and in the same way, after all the suspension arms are subjected to graded variable-amplitude tamping, one-time adjacent joint pressure semi-tamping primary tamping of the positioning coverage area of the working ship is completed, then secondary tamping is conducted, the tamping times determined by the test are achieved, and the tamping efficiency and quality are improved.
本发明涉及一种水下基床夯实施工方法，打夯机底部滑动于打夯工作船轨道上，打夯机吊臂为变幅吊臂；以打夯工作船为中心，根据轨道长度和吊臂幅度行程对基床进行区域分幅，确定打夯工作船位置后，使夯锤中心对准一分幅区域角点作为起夯点；启动打夯机，提锤打夯第一锤，打夯机滑动至夯锤半径行程后夯击第二锤，以此类推，边走边夯，逐锤逐锤打至该排列的末端，然后停止行走和打夯；然后将夯锤放置基床上，使吊臂无夯锤荷载后，改变吊臂幅度至下一级，进行下一排列打夯，直至该排列至另一端；依此类推，完成所有吊臂分级变幅打夯后，即完成本次工作船定位覆盖区域的相邻接压半夯初夯一遍，接着复夯，达到试验确定的夯击遍数，提高了夯击效率和质量。
