River channel excavation diversion method and cofferdam structure
The invention discloses a river channel excavation diversion method and a cofferdam structure, and belongs to the field of water conservancy projects. The method comprises the following steps: planning a riverway section needing to be deeply excavated in advance, and decomposing the riverway section needing to be deeply excavated into a riverway zone a, a riverway zone b and a riverway zone c from left to right; a flow guide ditch used for guiding incoming water is constructed in the river channel belonging to the river channel partition a along the river channel, and then a cofferdam with the same height as the dike a and the dike b is constructed at the position, located at the river channel partition b, of the center line of the river channel; and secondly, a riverway partition c is excavated on the right side of the cofferdam, diversion is conducted through the riverway between the cofferdam and the dike b and the riverway partition c, excavation of the riverway partition a is completed, a diversion pipe is laid at the bottom of the constructed riverway partition a, excavation of the riverway partition b is completed, and finally the whole deep riverway excavation operation is completed. The method has the advantages of being high in construction speed, easy and convenient to install, environmentally friendly, economical and efficient, and materials can be recycled for multiple times.
本发明公开一种河道开挖导流方法及围堰结构，属于水利工程领域。提前规划河道需要施工挖深的河道断面，并将需要挖深的河道断面从左到右分解为河道分区a、河道分区b和河道分区c；先在属于河道分区a的河道中延河道施工用以导流来水的导流沟，再在河道中心线处且位于河道分区b处施工与堤防a、堤防b等高的围堰；其次，在围堰的右侧开挖河道分区c，利用围堰与堤防b之间的河道以及河道分区c进行导流，再完成河道分区a的开挖，并在完成施工的河道分区a底部铺设导流管，接着对河道分区b完成开挖，最终完成整个挖深河道的作业。本发明发具有施工速度快，安装简便，材料可多次回收利用，以及绿色、经济、高效的特点。
