The invention discloses a dredging method suitable for full-tide-level maneuvering positioning operation under a long-piled wharf beam plate. The dredging method comprises the steps that an economical novel cutter suction dredger system is in place according to the dredging position under the plate, dredged materials are conveyed, positioning is conducted through an anchor cable pulley positioning and fixing system, first-section dredging operation is started, and multi-section dredging operation construction is conducted. The economical novel cutter suction dredger system is composed of a low-freeboard semi-submersible cutter suction dredger body, a high-power pump suction dredger, a mud conveying pipe, a mud floating hose and a mud barge. The high-power pumping ship can be moored on the periphery of a wharf by adjusting the length of the mud floating hose. Dredging operation under a high-pile beam plate is carried out through the economical and novel low-freeboard semi-submersible cutter suction ship body, the influence of high-pile wharf beam plate height limitation, a pile body structure and tide in an existing water transportation port wharf construction structure can be eliminated, the effective operation time of dredging work is greatly prolonged, and the dredging operation efficiency is improved.

    本发明公开了一种适于高桩码头梁板下全潮位机动定位作业的疏浚方法,该疏浚方法包括经济新型绞吸船系统按照板下疏浚位置就位、疏浚料输送、锚缆滑轮定位固定系统的定位、开始第一段疏浚作业、多段疏浚作业施工。本发明的经济新型绞吸船系统由低干舷半潜式绞吸船体、大功率泵吸船、输泥管、泥浮软管、泥驳组成。通过调整泥浮软管长度,可以将大功率泵吸船停泊于码头外围。本发明通过经济新型的低干舷半潜式绞吸船体进行高桩梁板下疏浚作业,可以排除了现有水运港口码头建设结构中高桩码头梁板限高、桩体结构及潮汐影响,大幅度提升疏浚工作有效作业时间,提升了疏浚作业效率。
