河道疏浚技术在河道整治中的运用分析

Analysis on the Application of River Dredging Technology in River Regulation

针对河道整治问题展开研究,提出了环保型刀头绞吸式挖泥船开挖方案,解决了岸边构筑物密集,施工布置困难的问题。结合淤泥制砖技术、良田改造技术,实现了河道疏浚淤泥的再利用。基于甘肃省河道整治案例的研究表明,河道疏浚技术的应用不仅可以改变河道淤积困境,减少两侧岸坡损坏、冲毁的风险,还可以带来更多生态、经济收益。

Aiming at the problem of river regulation,this paper puts forward the excavation scheme of environmental protection cutter cutter suction dredger,which solves the problems of dense structures on the shore and difficult construction layout.Combined with the technology of making bricks from silt and the technology of transforming fertile land,the reuse of dredged silt in river channel is realized.Based on the case study of river regulation in Gansu Province,it shows that the application of river dredging technology can not only change the predicament of river siltation,reduce the risk of damage and erosion of both banks,but also bring more ecological and economic benefits.
