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.技术岩石是一种混凝土块，最初设计用于在高水位排放期间保护河床。研究表明，该块体具有净化水体的能力和创造河流生态系统的功能。实验研究了如何提高块的动力学和环境能力。为了防止冲刷或沉积，在块体的顶部和孔内附加阴影的效果进行了研究。在几种类型的阴影测试，两个阴影类型附加到垂直孔的内部是最有效的保护冲刷和沉积。在上游侧顶部设置遮阳板可以减小冲刷速率，而下游侧孔内设置遮阳板则可以防止泥沙淤积.最近，人们试图恢复河流中被破坏的生态系统，并改善流域管理。我们提出了母亲的岩石，保持或创造生态系统沿沿着河岸。该地块由两个空间组成，两者都直接与土地相连。上部空间用石头填满，以便排水良好，因此应该保护堤岸免受破坏。下部空间计划用适合稳定植物植被的土壤填充。该块可用于稳定银行。创造野生动物栖息地，提供准自然景观。
