众所周知,现代我国生产的绞吸式挖泥船挖泥机械的控制系统没有连锁,是按孤立控制的原则设计的,并缺乏必要的安全设施,因此,在施工中,常常发生诸如尾桩倒伏,尾桩冲击提升油缸,拉断摆动缆,拨毁地龙等事故。在开阔水域的航道上施工时,必须投设浮标或标杆作为导标,以掌握疏浚航槽的方向和宽度。由于投放的浮标或安插的标杆,受风浪水流的冲击,所以定线误差较大,难免造成超宽或漏挖的质量事故。
It is known to all that the control system of the cutter suction dredger dredging machine produced in our country is not interlocked and is designed according to the principle of isolated control and lacks the necessary safety facilities. Therefore, during the construction, such as tail pile lodging, Tail pile impact upgrade cylinder, pull off the swing cable, dragged down the earth and other accidents. When constructing a waterway in an open water area, a buoy or benchmark must be used as a guide to grasp the direction and width of the dredging navigation channel. Due to the placement of the buoy or placement of the pole, by the impact of wind and waves, so the alignment error is larger, inevitably lead to wide or digging the quality of the accident.
