CBS基材生态护坡技术适用范围

Application scope of CBS substrate ecological slope protection technology

CBS基材生态护坡技术主要适用于各种类型的硬质边坡、坡度大于45°－90°的各种高陡边坡、以及受水流冲刷较为严重的坡体的浅层防护与植被恢复重建。其中硬质边坡包括各种风化程度的岩石边坡，混凝土边坡，浆砌石干砌石边坡等；各种高陡边坡除硬质边坡外，还包括高陡土切坡、堆积体边坡等；受水流冲刷较为严重的坡体主要指降雨侵蚀严重的坡地，湖泊、河流及水库的消落带等。由此，CBS基材生态护坡技术可应用于因工程建设开挖形成坡体的植被修复、采取工程硬化措施之后的坡体的植被重建、矿山采石场的生态恢复、裸露山体及堆积体的快速复绿及水土保持、湖泊、河流及水库消落带的植被恢复等。

CBS base material ecological slope protection technology is mainly suitable for various types of hard slopes, high and steep slopes with slope gradients greater than 45 -90, and shallow protection and vegetation restoration and reconstruction of slopes seriously scoured by water flow. Hard slopes include rock slopes with various weathering degrees, concrete slopes, dry masonry slopes, etc. High and steep slopes include high and steep soil cutting slopes, accumulation slopes, etc. Slopes with serious water erosion mainly refer to slopes with serious rainfall erosion, lakes, rivers and reservoirs. Fluctuating zone and so on. Therefore, CBS base material ecological slope protection technology can be applied to vegetation restoration of slope formed by engineering construction and excavation, vegetation reconstruction of slope body after adopting engineering hardening measures, ecological restoration of mining quarries, rapid greening of bare hills and accumulations, soil and water conservation, vegetation restoration of lakes, rivers and reservoirs.

一、坡体排水。为减小坡面汇水量，降低过大冲刷带来的CBS基材层失稳风险，可沿坡体外侧布设截流沟，沿坡面平台（如果有）内侧布设排水沟。排水沟由中间向两头设置一定比降，与截流沟相连，使地表径流最终进入总排水沟。截流沟和排水沟断面尺寸可根据截流面积及降雨强度确定。

First, slope drainage. In order to reduce the catchment of water on the slope and reduce the risk of instability of CBS substrate layer caused by excessive scouring, intercepting ditches can be arranged along the outside of the slope and drainage ditches can be arranged along the inside of the slope platform (if any). The drainage ditch is connected with the interception ditch by setting a certain ratio from the middle to the two ends, so that the surface runoff eventually enters the total drainage ditch. The section size of the trench and drain can be determined according to the interception area and rainfall intensity.

二、养护系统的布置。植被的生长离不开水分，特别是植物发芽初期，必须保证水分的供应，同时对于可能出现的干旱，也有必要补充水分。为便于水分浇灌，可在CBS基材基材施工完成后，进行养护系统的安装。养护系统的布置及喷头的数量根据边坡附近的水源情况和坡面植被生长需水量确定。

Two, maintenance system layout. Vegetation growth is inseparable from water, especially in the early stage of plant germination, water supply must be guaranteed, and for possible drought, it is also necessary to supplement water. In order to facilitate water irrigation, the maintenance system can be installed after the construction of CBS substrate material is completed. The layout of the maintenance system and the number of sprinklers are determined according to the water source near the slope and the water requirement of vegetation growth on the slope.
