框架结构护岸新技术在城市河道中的应用

好溪堰河是贯穿浙江省丽水市主城区的一条千年古河道,在河道整治过程中,受制于河道周边的密集建筑物,传统的河道护岸技术均难以同时满足水利、市政、交通及景观的多元化要求。在分析其他创新河道护岸技术特点及存在问题的基础上,提出了适用于城市河道的桩柱式、框柱式两种框架结构护岸新技术,这两种护岸在维护河道周边建筑物稳定的同时,均具有不加深河床就可拓宽河道过流断面、不减少河岸用地、保持岸路畅通、改善水质及生态效果、提高亲水性等优点,在丽水好溪堰河水系整治工程中应用较为成功。

Application of New Technology of Frame Structure Revetment in the Urban River

Haoxiyan River is an ancient river with thousand years history which flows through the main urban areas of Lishui city in Zhejiang province .During the channel improvement , there are restricted space due to dense buildings around the river ,therefore the traditional technology of river improvement are difficult to meet the diversified requirements from water conservancy ,municipal ,traffic and landscape project .Based on the analysis of features and existing problems of other new technology ,two new technologies of frame structure revetment are proposed which can maintain the stability of building surrounding river and widen the river channel without deepening the river channel ,it also can reduce the land use on the riverside and keep road on river bank coherent ,thus improve the water quality and the ecological effect and promote the human-water harmony .In conclusion the application of frame structure revetment is successful in the pro-ject of water system construction of Haoxiyan river in Lishui city .
