Method for grooving cutter suction dredger while tide exists in shallow water area
The invention provides a method for grooving a cutter-suction dredger while the tide in a shallow water area, which is characterized in that the method generally adopts the thinking of grooving the cutter-suction dredger at a high tide level, turning the dredger and keeping the dredger horizontally in a low-tide level groove, the cutter-suction dredger constantly adjusts the posture of the dredger in a groove, and the dredger is switched between a construction state and a tide waiting state; according to the method, a mathematical model is established according to cutter suction dredger body scale parameters, construction parameters, water depth and tide level data, the tide level meeting the construction conditions is screened, the tidewhile water level, the entering point time point, the grooving width and the turning time point are calculated, and the method can be directly used for guiding the cutter suction dredger to conduct tidewhile grooving in the shallow water area. By means of the method, the excavation work amount and the waste volume can be reduced, the construction cost is reduced, the grooving efficiency is improved, and the construction period is shortened.
本发明提供一种绞吸船浅水区趁潮开槽的方法，其特征在于该方法总体采用绞吸船高潮位开槽及船舶转体、低潮位槽内横卧养船的思路，绞吸船始终在挖槽内不断调整船舶姿态，在施工状态和待潮状态之间切换，直至平槽段长度超过船长后正常施工，本发明根据绞吸船船体尺度参数、施工参数、水深及潮位数据建立数学模型，筛选满足施工条件的潮位，计算趁潮水位、进点时间点、挖槽宽度、转体时间点，可直接用于指导绞吸船浅水区趁潮开槽，采用本发明的方法可减少开挖工程量和废方量，降低施工成本，提高开槽效率，缩短工期。
