新型砌块水土保持系统的应用研究

Application study on interlocking concrete block in the soil and water conservation system

我国江河湖库众多,同时水土流失日趋严重,流失面积及速度已逐年增加。每年水库除险加固和河流治理等投资数百亿元,随着人们环保意识的加强,特别在近几年以长江和黄河为重点的堤防建设护岸工程中,联锁式砼砌块水土保持系统已逐渐成为我国水土保持领域中最重要的一种全新解决方案,被广泛采用。该系统既能有效防止水土流失、长久地防止坡面冲刷和保持坡体稳定,又能代替成本较高的常规护面,具有较广的推广应用前景。联锁式砼砌块水土保持系统是由多个独立的砼砌块相互啮合组合在一起的联锁矩阵,联锁式砼砌块铺面在各种动、静水条件下具有良好的整体稳定性,铺设于渗水土工布上。能有效保护土体不受水流冲刷和浸泡破坏。该系统在欧美已有多年的历史,是被工程实践证明了的性能卓越、经济实用、美观环保、可持续发展的水土保持系统,可广泛应用于河道和灌渠衬砌、沿海防潮堤、水库大坝边坡加固、铁路、高速公路边坡等防护和城市绿化工程。

In our country,there are a number of rivers,lakes and reservoirs.The problem of soil erosion is becoming serious day by day,and the area and speed of soil erosion are increasing year after year.Every year several ten billions of yuan are invested in reservoir reinforcement and river control by the government.With the strengthening of environmental protection consciousness,the soil and water conservation system of interlocking concrete block is becoming the most important new solving plan in the field of soil and water conservation,especially in the levee construction and bankprotection works focused on the Changjiang River and the Huanghe River in recent years.It can protect from soil erosion effectively and slope erosion permanently to keep the slope stable.It can also replace the conventional facing with high cost.It is of wide application and dissemination.This system contains several independent concrete building blocks engaged each other.The interlocking concrete block paving is of fine monolithic stability in various hydrodynamic and hydrostatic conditions.If it is laid on the infiltration geomembrane,it can protect soil from water erosion.This system has been used for years in the West.It is proved economical and beautiful with remarkable performance.it can be widely used in river and canal lining,slope reinforcement of sea embankment and reservoir,slope protection of railway and expressway and city afforestation projects.
