摘　　要：某河道是贯穿县域的主要行洪河道,河道干流疏浚长度35.50 km。河道疏浚断面采用单一梯形断面,平均疏挖深度1.70 m。根据工程具体情况合理划分施工段,分段布设测量控制网,复核开挖断面和开挖工程量,测放开挖边线和高程控制桩河道开挖前,制定施工方案、配套施工机械设备。文章详细分析了疏浚工程土方开挖施工工艺,特别是水上及水下土方开挖的施工方法。土方开挖以机械化施工为主,并辅以人工配合实施作业保证开挖精度。A river channel is the main flood channel running through the county.The length of the river main stream dredged is 35.50km.The river dredging section adopts a single trapezoidal section with an average dredging depth of 1.70 m.According to the specific situation of the project,the construction section is reasonably divided,the measurement and control network is arranged in different sections,and the excavation section and the excavation quantity are reviewed.Before the excavation of the excavation edge line and the elevation control pile,the construction plan and supporting construction machinery and equipment are formulated.The construction technology of earthwork excavation in dredging engineering is analyzed in detail in this paper,especially the construction method of earthwork excavation above water and under water.Mechanical construction is the main method of the earthwork excavation,supplemented by manual cooperation to ensure the accuracy of excavation.
