生态混凝土护坡在河堤加固中的应用

Application of eco-concrete slope protection to embankment reinforcement

现浇透水·植生高强生态混凝土技术主要解决了生态混凝土强度与孔隙率的矛盾,在实现岸坡长期稳定的同时,实现了水下部分的透水生态循环,水上部分的植生生态平衡以及整个生态系统的可持续发展。此项技术在合肥市南淝河某段河堤改造中对其与加固方案的综合使用,进行了一定的探索。文中对于这种护坡型式与加固方案的结合进行了研究,阐述了技术要点,介绍了施工工艺,分析了工程应用效果。

The technology of high-strength cast-in-situ greening porous eco-concrete can solve the contradiction between the strength and the porosity of the eco-concrete, and then not only the porous ecological cycle through the under-water part of the concrete slope protection is realized, but the sustainable development of both the green-growing ecological equilibrium on water and the entire eco-system related are also realized, while the long term stability of the embankment can ensured. The technology is comprehensively used in the scheme of the embankment reinforcement during the improvement of a section of Nanfeihe River in Hefei City; in which certain trials and experiments are carried out. The study on the combination of both the type of the slope protection and the reinforcement scheme is given herein, including the expatiation of the key points of the technology, introduction on the construction technique and the analysis on the effect of the engineering application.
