摘要:
Disclosed is a method for foresting a vertical wall and a highly-inclined surface and an aggregate container, a shelf assembly, and a water supply apparatus used for the method. The shelf assembly (10) includes a support unit (12) and a support plate (20). The support unit (12) has a fixing leg (14) fixed to a reinforcement soil layer (3), and a load support unit (16) is positioned at the front end of the fixing leg (14) and is forced against and supported on a vertical wall (7) or an inclined surface at the front end of the reinforcement soil layer (3). The load support unit (16) has a support leg (18) extending from its front end to be inclined in the opposite gravitational direction. The support plate (20) is supported on the support leg (18), and vegetation soil (40) is placed on the support plate (20). A horizontal supply tube (36) is positioned inside the vegetation soil (40) with both ends connected to vertical supply tubes (30), which have a predetermined interval between them. Water supply tubes (38) are installed on the horizontal supply tube (36). The water supply tubes (38) are filled with a filler (38), and pressure-reduction valves (37') are installed on connection tubes (37), which connect the water supply tubes (38) and the horizontal supply tube (36). The shelf assembly (10) can support the load of the vegetation soil (40) more efficiently, and water is supplied into the vegetation soil (40) more effectively.

PROBLEM TO BE SOLVED: To provide a sand movement preventive construction method, a vegetation improving method thereby, and cylindrical fabric for a sandbag optimal for these sand movement preventive construction method and vegetation forming-improving method, by using the lightweight sandbag superior in folding-up performance, easy in transport even in a desert area, superior in ease of work by reducing a load of a worker, and capable of minimizing use of resources, as a material of the sandbag. SOLUTION: This sand movement preventive construction method is provided for preventing the movement of sand by placing the cylindrical sandbag formed of the cylindrical fabric and filling sand inside, on a sandy place surface by crossing a plurality. In the sand movement preventive construction method, a placing pitch of the cylindrical sandbag is desirably set to 3-30 pieces/10 m, and the cross-sectional area of the cylindrical sandbag is set to 10 to 400 cm 2 . The vegetation forming-improving method is also provided for rearing desired plants on the sandy place surface between the crossed/ placed cylindrical sandbags. The cylindrical sandbag is formed of the cylindrical fabric for the cylindrical sandbag knitted by polylactic acid fiber. COPYRIGHT: (C)2009,JPO&INPIT

PROBLEM TO BE SOLVED: To solve problems in conventional technology wherein there is a defect of providing neither a retreat place nor a place for protected growing of fish because a passage provided with much trouble is buried with slurry if an earth retaining frame is installed on foot protection, the river bottom, or the like, and further it is difficult to fill inside filling stones, particularly to support from below in the case of a tubular or cylindrical pipe body or net body, and there is a possibility of losing stability to worsen the whole balance or to damage the pipe body or net body if the way of filling is not good. SOLUTION: This fish net gabion 1 is constituted by building a cylindrical or elliptic cylindrical gabion body inside to pass through laterally or longitudinally, supporting a part of at least the lower side face of the gabion body by a stone product having a recessed circular arc surface, and filling the filling stones such as stone end pieces in a remaining void space in the gabion.

PURPOSE:To easily construct a cell revetment by a method in which plural steel cells are uprightly erected at a given interval on the upside of a base steel casing, and connected with each other by paired arcs facing each other, and soil is packed into the steel cells. CONSTITUTION:Plural steel cells 5 are installed and welded at a given interval on the upside of the steel casing 11 of a base 3 with an air chamber formed of a high-strength film 13. Paired arcs 7 are each set between the cells 5 in a mutually facing manner, the cells 5 are welded on the upside of the cell 11, and connecting pieces 9 are welded to the cells 5 on both ends to construct a structure 1. The structure 1 is towed to a construction site and settled on a mound 21 while adjusting ballast in the base 3, and a filling material 23 is placed into the base 3. New structure 1 is then settled and connected through connecting pieces 9, a filling material is placed, and the structures 1 are connected in order.

PURPOSE:To simplify the forming work of a vegetation foundation on a face of slope, by a method wherein grooves are formed at intervals in a hard slope ground with a jet of water, and the grooves are filled and the whole of a face of slope is covered with a vegetation material. CONSTITUTION:Grooves 2 are formed in a hard slope ground 1 at intervals in a vertical direction, and the groove recess is excavated with a jet of water to form a vertical cut surface 2a and a horizontal cut surface 2b of the groove 2. The shape of the groove 2 may be a round hole or groove. The interior of the groove 2 is filled with a vegetation material 4, the whole surface of the face of slope is covered with the vegetation material 4, and the vegetation material is prepared by mixing a fertilizer, a fiber material, a self-adhesive, and seeds in cultivated soil. This enables simplification of a work of forming a vegetation foundation on the face of slope.
