River dredging construction method
The invention relates to the technical field of water conservancy dredging, in particular to a riverway dredging construction method which comprises the steps that the water depth terrain is remeasured before dredging, a long-arm excavator is adopted to conduct grooving on the right side of a riverway along a river bank to form a dredging groove, and a drag suction dredger is adopted to conduct pushing and sweeping from the left side to the right side of the riverway obliquely in the river water flow direction so that an inclined slope can be formed on the bottom face of the riverway. The drag suction dredger is controlled to carry out silt suction operation for multiple times along the inclined slope surface, and after a period of time, the long-arm excavator is controlled to excavate back silt in the right dredging groove out; the cutter suction dredger is controlled to conduct dredging operation from the left side of the river channel; and the drag suction dredger is controlled to conduct dredging operation in the middle of the river channel in the river water flowing direction, and the bottom face of the river channel is lower than the required height. The bottom face of the river channel is pushed and swept into the inclined slope face through the drag suction dredger, then the cutter suction dredger is adopted for working from the high position of the inclined working face, the back silting situation can be effectively reduced, and the construction quality and efficiency are improved.
本申请涉及水利疏浚的技术领域，尤其是涉及一种河道疏浚施工方法，其包括疏浚前复测水深地形，采用长臂挖机沿着河岸在河道右侧挖槽形成清淤槽，采用耙吸式挖泥船沿河水流向斜着从河道左侧向右侧推扫，使河道底面形成倾斜坡面，控制耙吸式挖泥船沿着倾斜坡面进行多次吸淤作业，一段时间后控制长臂挖机将清淤右槽内的回淤物挖出；控制绞吸式挖泥船从河道左侧进行清淤作业；控制耙吸式挖泥船沿着河水流向在河道中部做清淤作业，使河道底面均低于要求高度。本申请通过耙吸式挖泥船将河道底面推扫成倾斜坡面，再采用绞吸式挖泥船从倾斜的工作面高处开始作业，可以有效减少回淤情况，提高施工质量和效率。
