强夯施工工序是利用强夯机将一定质量的夯锤吊起,在其达到一定的高度后释放,使夯锤自由下落,以一定的速度冲击地面,从而使地面达到所需的密实度。然后利用离合器自由落钩,使脱钩器迅速下降到地面,由机组人员将吊钩与夯锤连接,将夯锤起升,重复以上工序。1.改进履带架与活动节结构(1)故障现象及原因分析某工地施工现场,1台由桁架臂履带吊改装的强夯机释放夯锤后,整机出现振动幅度和频率过大现象,严重影响强
Dynamic compaction construction process is the use of tamping machine will be a certain amount of ram hammer lifted, after it reaches a certain height release, the rammer free fall to a certain speed impact on the ground, so that the ground to achieve the required density. And then use the clutch free-fall hook, so that the decoupling device quickly dropped to the ground, the crew will hook and rammer connected to rammer lifting, repeat the above process. 1. Improve the structure of crawler frame and movable section (1) Analysis of the failure phenomenon and its causes After a rammer is released by a tamper modified by a truss boom crawler crane, the vibration amplitude and frequency of the whole machine appear excessive, Seriously affected
