【摘要】：近年来,以绿化混凝土技术为依托的水岸生态防护技术纷纷涌现,在一定程度上推动了我国生态水利事业的发展。但随着这种技术的大量推广,一些严重的问题,如植被持续再生和板块防护稳定问题日益凸显,出现的典型现象是植被枯萎,不可再生,板块无砂混凝土体破碎,整体稳定性失衡等,严重威胁河岸的稳定安全。本文在系统分析目前典型的生态岸坡防护技术基础上,以吉林省水利科学研究院专利绿化混凝土技术为依托,对板块的外框构成、板块强度和耐久性、板块适用植物、板块防护能力和板块制作等进行了较为系统的研究,提出了板块在设计应用时所需的各种要素。经过研究得出,带有凹槽的绿化混凝土六边形板块是较为合理的板块型式,能够有效增加植被面积、降低吸热效果、改善植被生长环境；提出了板块强度与水泥和骨料用量的一般规律,解决了板块在严寒地区推广应用的关键问题；推导出了板块在不同水流冲刷条件下板块厚度与波高和流速等重要要素的一般性关系,解决了板块设计中的一些重要问题；总结出四季气温变化与绿化混凝土板块表面温度变化及常见植物在绿化混凝土表面播种、生长的规律；通过实验广泛播种花草,实现了植物选用的广谱性：研制出了适用的轻便型板块制作机具,为绿化混凝土防护技术的推广应用奠定了良好的基础。本文的研究成果对于进一步规范绿化混凝土板块护坡技术的发展,改善传统水岸防护环境,加强生态水岸建设具有一定的积极意义。
[Abstract]:In recent years, waterfront ecological protection technology based on greening concrete technology has emerged one after another, which has promoted the development of ecological water conservancy in China to a certain extent. However, with the popularization of this technology, some serious problems, such as vegetation regeneration and plate protection and stability, are becoming more and more prominent. The typical phenomena are vegetation withered, non-renewable, slab sand-free concrete body broken. The unbalance of the whole stability seriously threatens the stability and safety of the river banks. On the basis of systematic analysis of typical ecological bank slope protection technology at present, based on patent greening concrete technology of Jilin Water Conservancy Research Institute, this paper deals with the construction of outer frame of the plate, the strength and durability of the plate, and the suitable plants for the plate. The ability of plate protection and plate making are studied systematically, and various elements for plate design and application are put forward. Through the research, the green concrete hexagonal plate with grooves is a more reasonable plate type, which can effectively increase the vegetation area, reduce the heat absorption effect, improve the vegetation growth environment; The general rules of plate strength and cement and aggregate content are put forward, and the key problems of plate popularization and application in cold regions are solved. The general relationship between plate thickness, wave height, velocity and other important factors under different flow erosion conditions is deduced, and some important problems in plate design are solved. Summing up the variation of temperature in four seasons and the change of surface temperature of greening concrete plate and the regularity of planting and growing of common plants on the surface of greening concrete. The wide spectrum of plant selection has been realized: a suitable portable plate making machine has been developed, which has laid a good foundation for the popularization and application of greening concrete protection technology. The research results of this paper have certain positive significance for further standardizing the development of slope protection technology of greening concrete plate, improving the traditional waterfront protection environment and strengthening the construction of ecological waterfront.
