摘要： PROBLEM TO BE SOLVED: To acquire the subsurface infiltration execution method of rain water continuously displaying a rain-water infiltration function by burying a rain-water infiltrating product under the state, in which a water-permeable sheet material apparently closing holes and slits, from which rain water is infiltrated, is interposed, and filling the outside of the product with regenerated-resource aggregate. SOLUTION: A cylindrical vinyl chloride pipe 2 with holes 6 is used as an infiltration inlet. A water-permeable sheet material 5 consisting of a nonwoven fabric is wound on the outer circumference of the vinyl chloride pipe 2. A woven fabric, a geo-grid, a geo-net, a geo-composite, a wire gauze, etc., can be employed as the water-permeable sheet material 5 besides the nonwoven fabric. The rain-water infiltration facility formed in this manner is buried, the outside of the facility is filled with regenerated resource aggregate 3 composed of a concrete waste material, and the facility is backfilled with backfilling soil 4. Fine grain sections in the regenerated resource aggregate 3 are difficult to infiltrate from the outside without damaging water permeability by interposing the water-permeable sheet material 5 in this manner. Accordingly, an infiltration function can be displayed continuously for a prolonged term.

摘要： PURPOSE:To firmly join a mold frame and a concrete structure by constructing a concrete structure by using a mold frame which is formed by laying aggregate which is formed by attaching the bonding agent such as cement on the surface of the artificial or natural aggregate and forming the continuous cavities. CONSTITUTION:The aggregate which is formed by attaching the bonding agent of cement or resin paste on the surface of the artificial or natural aggregate which is adjusted to a necessary particle size is laid, and curing is performed, and a mold frame 1 is manufactured. The mold frame 1 possesses water- permeability, and cavity is generated between the aggregates, and the cavities communicate each other, and a continuous gap is formed. When a concrete structure is constructed by using the mold frame 1, the excessive water W and the air A in the concrete 3 are excluded through the continuous gap, and mortar flows into the gap and hardened, and the mold frame 1 and the concrete 3 are firmly joined. Accordingly, the excessive water can be easily removed during the curing of concrete, and the joint performance with the laid concrete can be improved.

摘要： PURPOSE:To efficiently treat waste water by constructing a support so as to form a membrane on which aerobic bacteria propagate preferentially on the outer surface and a membrane on which anaerobic bacteria propagate preferentially in the hollow part. CONSTITUTION:A biological membrane support 1 made of a hollow said body having an internal space which communicates with the outer surface through many pores 2 is immersed in waste water in a treatment tank under aeration. An aerobic biological membrane is formed in the vicinity of the outer surface of the support 1. Dissolved oxygen in the waste water permeating into the support 1 through the pores 2 is consumed by aerobic bacteria, the hollow 3 in the support 1 becomes an anaerobic state and anaerobic bacteria propagate preferentially in the hollow 3. Biological membranes can stably be formed over a long period by impregnating glucose or heptone into the support.

摘要： PROBLEM TO BE SOLVED: To prevent local clogging from occurring by providing a gutter having a plurality of drilled parts on the pavement side in the transverse direction, and letting a water permeable concrete block having a cutout part cutting out one corner part in the lengthwise direction adjacent to this so as to communicate the drilled parts to the cutout part. SOLUTION: A gutter 11 of which the side upper edge is formed with a plurality of drilled parts 111 on the pavement side in the transverse direction is provided on the end part of pavement. A used water permeable concrete block 21 is formed into a nearly square pillar of which one corner part in the lengthwise direction is cut out arc-likely or angle-likely so as to form cutout part 211. The water permeable cncrete block 21 and the gutter 11 are adjoined each other so as to communicate the drilled parts 111 to the cutout part 211. consequently, the cutout part 211 of the water permeable concrete block 21 becomes a led-out gap for rain water, rain water is derived without being locally concentrated, and hence local clogging can be prevented from occurring.
