河道生态护岸设计中的底泥固化技术中试
Pilot Scale Test of River Sediment Solidification Technology for Ecological Revetment Design
摘要
Abstract
Nowadays,some small and medium sized rivers in Chongming Island are confronted with the problems of riverbed sedimentation and black and malodorous river.A pilot scale test for the ecological revetment design of a 60-meter river in Gangyan Town,Chongming District,Shanghai,was carried out based on the theory of sediment solidification and stabilization.According to the actual situation of the riverbank,solidified sediment and slope soil were taken as raw materials,and the construction was carried out based on Code for Design of Levee Project (GB 50286-2013).Stones or building wastes were stacked and concreted on the riverbed to reinforce the foundation.Eco-bricks of building material type and light type were utilized to construct revetment Plants were cultivated on the slope after in-situ solidification of the slope soil layer.All these measures not only stabilized the slope soil,but also beautified the environment and restored the natural habitat along the river.The project analysis demonstrated that the revetment structure was stable in 90 days and the leaching toxicity met the national standard.pH of the river water stayed at alkalescency level and no significant variation was observed.Natural ecosystem around the riverbank has been recovered.关键词
