本文介绍的是一种用生物措施整治河道的工程——深栽柳树坝.适用范围主要是我国北方多沙河道.做法是用深栽柳树做成活柳坝,籍其深植的根系和土壤盘结成牢固的基础,靠其被定型修剪的枝干形成坝体,以起到改善河势、缓流促淤、固岸护滩、束水攻沙的作用.还可减轻在河道植树与行洪的矛盾.优点是可就地取材,工程造价低.在安平县用这种措施整治滹沱河,仅三年时间,坝体就枝叶郁闭,根系盘结,初见成效. 本文通过实例,具体阐明了深栽柳树坝的工程结构、施工方法、管理措施以及观测成果.最后指出了生物治河工程是整治河道的一种有效措施.
This article describes a kind of biological measures to harness the river project - deep planting willow dam. The scope of application is mainly the northern Dasha River. The practice is to use deep willow made of live Willow dam, its deep roots and soil Plate formed a solid foundation, by its stereotypes pruning of the branches to form a dam body, in order to play to improve the river, slow flow silt, solid shore beach, water beam attack the role of sand. Can also reduce the river planting trees and The advantages of row flood, the advantage is available locally, the project cost is low .In this measure to rectify the Houtuo River in Anping, only three years, the dam on the canopy and the root, the root system, initial results.In this paper, through examples, Concretely expounded the engineering structure, construction method, management measures and observation results of the deep planting willow dam.At last, it points out that the biological river regulation project is an effective measure to rehabilitate the river course.
