Dredging method for dredging below wharf
The invention discloses a dredging method for dredging below a wharf. The dredging method comprises the following steps: S001, preparation before construction; s002, an obstacle removing ship is adopted for fixed-point removing and fishing; s003, a grab dredger is adopted to dig a temporary mud storage tank at the front edge of the wharf; s004, an excavation type dredging device is adopted to conduct dredging and dredging on the lower portion of the wharf; and S005, the excavation type dredging device is withdrawn. The dredger head is directly used for underwater dredging, a small ship machine does not need to enter a bridge opening during dredging construction, only the scraper bucket of the dredger needs to be directly controlled to enter the position below a wharf for underwater dredging, the labor cost is reduced, the time for workers to enter the bridge opening for operation is greatly shortened, the workers basically work outside the bridge opening, and the working efficiency is greatly improved. The potential safety hazard that workers cannot evacuate in time when entering the bridge opening for operation due to the rising tide of seawater is avoided, the situation that the workers cannot work due to the influence of tide water is greatly improved, the time utilization rate is remarkably increased, and the dredging efficiency is greatly improved.
本发明公开了一种码头下方疏浚清淤方法，包括以下步骤：S001、施工前准备；S002、采用清障船舶进行定点清除打捞；S003、采用抓斗挖泥船在码头前沿挖临时贮泥槽；S004、采用挖掘型疏浚装置对码头下方进行疏浚挖泥；S005、撤离挖掘型疏浚装置。本发明直接使用耙头水下疏浚，在疏浚施工时不需要小型船机进入桥洞，只需直接控制疏浚船的耙斗进入码头下方进行水下疏浚，不仅减少了人工成本，极大缩短了工人进入桥洞作业的时间，而且工作人员基本在桥洞外作业，避免了工人进入桥洞作业因海水涨潮来不及撤离的安全隐患，使得受潮水影响无法作业的情况得到很大的改善，时间利用率显著提升，疏浚效率得到很大提高。
