BLOCK FOR FORMING LEADING PASSAGE, AND PANEL MEMBER AND FRAME FOR CONSTRUCTING WALL BODY WITH LEADING PASSAGE

WIPO Patent Application WO/2004/038105

A1

A block for forming a leading passage, characterized by having a ridge line, a recess line or a step on the front face of the block, so that, when a plural number of the blocks are used to form a continuous leading passage by piling up the blocks, the ridge line, recess line or step of each of the blocks continues between the blocks of which end portions are adjacent to each other. The ridge lines, recess lines or steps may be arranged in different directions in blocks of upper steps and blocks of lower steps so as to form the leading passage by uncoursed masonry. The leading passage may have a flat portion on an end portion of or the center of the front face of the blocks. A slope passage completed on a wall body face makes it possible that amphibians such as frogs and newts, and even insects such as larvae of fireflies, moves from water to land and in the opposite direction.
