摘要： PROBLEM TO BE SOLVED: To provide a construction method which is easy to handle due to light weight and capable of executing work with safety and easily following up with an uneven slope and restricting a cultivated soil stably while holding the strength as a scaffolding during the execution of work and further promoting the growth of seeds of vegetation. SOLUTION: A point of intersection 13 of a hexagonal lattice pattern 12 predetermined on a substrate 11 at a construction site is marked. Support posts 17a and 17b are erected at the marking point 14. Band-like synthetic resin made nets 20a to 20e, while being stretched, are mounted on the posts 17a and 17b, thereby forming a honey comb-like structure 30 where earth and sand are filled up in a frame enveloped with the nets 20a to 20e.

摘要： PURPOSE: To easily form a slope at low cost and to prevent an L-shaped net member from being easily deformed due to pressure of embankment. CONSTITUTION: An embankment reinforcing sheet is laid over the surface of the ground. An L-shaped net member 20 made of metal is disposed on the surface of the ground, where a slope is to be formed, with an upper side portion 20a of the member oriented toward the side of the slope of the surface of the ground. A reinforcing cap 40 made of metal is mounted to the upper edge of the portion 20a of the member 20. Sand and earth is poured into the member 20 from above the embankment reinforcing sheet 50. By repeating these steps, a slope of embankment having a desired height can be formed.

摘要： PURPOSE:To provide a waste water treatment method in which the partial oxidation of organic compounds in waste water can be conducted stably with a photocaralyst making the following biological oxidation treatment easy and good biological oxidation treatment efficiency is given. CONSTITUTION:Waste water D is introduced into a waste water receiving part 3 quipped with a cathode 3a having titanium oxides at least in its surface layer, and an anode 5 having platinum or nickel at least in its surface layer is contacted with the waste water D to make a circuit. The surface of the cathode 3a is irradiated with electromagnetic waves such as sunlight and ultraviolet rays so that oxygen is generated on the surface of the cathode 3a by the decomposition of water. Organic compounds in the waste water D are partially decomposed by the oxygen to make the biological treatment easy. Then the waste water D is treated in a biological catalytic oxidation tank 2 arranged downstream from the wastewater receiving part 3.

摘要： PROBLEM TO BE SOLVED: To prevent concrete from entering by arranging fiber structures having water repellent performance in both sides of a three-dimensional structure formed by twining bristle yarn between an impermeable sheet and a permeable sheet into a Roman figure III shape. SOLUTION: A belt-shaped impermeable sheet 18 and a permeable sheet 32 are faced to each other and a long crimped bristle yarn is twined between the both sheets 18, 32 so as to form a three-dimensional structure 14. Fiber structures 33, 33 having water repellent performance are arranged into a Roman figure III shape with the three-dimensional structure 14 set in the center so that the three-layer structured or a sandwich structured drain material 31 is constituted. Among the fiber structures 33 are a nonwoven fabric composed of a fiber having water repellent performance such as polyolefine adding no oil, tow, and felt. This constitution can prevent concrete from entering into the three-dimensional structure 14, when the concrete is placed between a shotcrete surface and a form.
