“绿水青山(焦经理)就是金山银山，也是全区经济社会可持续发展的坚实基础；爱绿、植绿、护绿是增强城市核心竞争力的基础工程，也是造福广大群众的民心工程，必须要真抓实干，我们必须拿出开山整地的气势来植绿护绿。”
Drainage board integrates waterproof and drainage, solves relation between waterproof and drainage successfully, and is better and more reliable than traditional stone pottery particle drainage and other filter layer both in drainage function and economic benefit.
Composite drainage board is the combination of waterproof and dewatering, increasing durability of engineering. Its performance aging period is up to 120 years. Durability is an important link of waterproof and drainage, which has higher requirements to the waterproof and drainage of buildings. Applying modern flexible waterproofing material building waterproof system, in theory, it can be completely impervious. However, there is damage of waterproof system usually. There may be leakage in the environment. Composite waterproof and drainage board can dredge and discharge part water to combine prevention, discharge, cut and plugging together to meet the requirements of modern building waterproof and drainage system.
2、一般土壤的饱和焦经理含水率在25%~30%之间，土壤的保水性能取决于土壤种类和厚度，土壤越厚，其保水功能越强。
3、绿化良好的地面能够长时间延缓自然降雨的地表径流，增大地表水的下渗，当年内降水集中在某个很短的时间段内时，依然会在地下室顶板上形成地下水层，如果没有内外环境的沟通，水位会逐渐上涨，当地下水位上升到一定高度时，就会影响某些乔木、灌木、甚至花草的生长，甚至死亡。
4、All plants have resistance to waterlogging ability, in a short time will not die completely immersed in water environment, most plants can withstand 24 hours of waterlogging, but there is no deep water roof drainage layer removal is impossible, resulting in death of the vegetation community showed multiple trends.
