HABITABLE MAT FOR AQUATIC ANIMAL AND PLANT, REVETMENT STRUCTURE USING MAT FOR RIVER, BOTTOM CONSTRUCTION USING MAT FOR RIVER, MARSH AND LAKE, AND REVETMENT BUILDING METHOD USING MAT FOR RIVER, MARSH AND LAKE

摘要

PROBLEM TO BE SOLVED: To provide a habitable mat that can be built in a short time and at a low cost by utilizing wood chips, which has a simple construction, a light weight with excellent portability and is capable of building a greening habitable region at the levee of a river or lake for aquatic animals and plants, a revetment structure using the mat for a river, a bottom structure using the mat for a river, marsh or lake, and a revetment building method using the mat for river, marsh or lake. SOLUTION: A mat 10 for the habitat of aquatic animals and plants is formed by filling up a water permeable bag having a plurality of pores permitting the entry and exit of the aquatic animals and plants with wood chips and then closing the mouth of the bag; a plurality of pile members 36 are driven into the ground at the shore of a face of slope of a levee 34; the habitat mat 10 is arranged in contact with the pile members 36; and a space between the habitat mat 10 and the face of slope of the levee is filled up with a supporting bed. Also, the habitat mat 10 is laid on a river floor or lake bottom, and a dead weight is stacked on the top surface of the mat thereby constituting a bottom structure.
