项目摘要

1. Techno-rock is a concrete block which was originally designed as a protector of the riverbed during high water discharge. It is revealed that the block has a water purifying ability and a function of creating ecosystem in rivers. Experiments were performed to investigate how to enhance both dynamical and environmental abilities of the block. In order to protect scour or sedimentation, effects of attaching shades at the top and the inside a hole of the block were examined. Among several types of shades tested, two-shades type attached to the inside of the vertical hole were most effective to protect both the scour and the sedimentation. Shades sttached at the top of the upstream side reduced the scouring rate, whereas shades in the hole of the downstream side prevented the sedimentation.2. Very recently, attempts have been made to restore damaged ecosystems in rivers and to improve watershed management. We have proposed the Mother's Rock which maintains or creates ecosystems along riverbanks. The block consists of two spaces, both are directly connected to the land. The upper space is filled with stones to drain well, so that banks should be protected from failure. The lower space is planned to be filled with soil suitable for stabilizing plant vegetations. The block can be useful in stabilizing the bank. creating wildife habitat and providing quasi-natural landscapes.

1. Techno-rock 是一种混凝土块，最初设计用于在高流量时保护河床。据透露，该区块具有净水能力和创建河流生态系统的功能。进行实验以研究如何增强块的动态和环境能力。为了防止冲刷或沉积，检查了在块的顶部和孔内部附加阴影的效果。在测试的几种类型的遮光罩中，安装在垂直孔内部的两种遮光罩类型对于保护冲刷和沉积最为有效。上游侧孔顶加设遮光罩可降低冲刷速度，下游侧孔洞内加设遮光罩可防止沉淀。2．最近，人们尝试恢复受损的河流生态系统并改善流域管理。我们提出了母亲之石，它可以维持或创造河岸生态系统。该街区由两个空间组成，两者都直接与土地相连。上部空间填满石块，以利于排水，防止堤坝崩塌。下部空间计划填充适合稳定植物植被的土壤。该封锁对于稳定银行很有用。创建野生动物栖息地并提供准自然景观。
