摘要： PROBLEM TO BE SOLVED: To improve the durability and corrosion resistance of a flexible part of a flexible precast culvert, to secure the design expansion quantity and eccentric quantity to a work execution error of footing concrete or the like and to make repair work and confirmation work relatively easy. SOLUTION: A pair of spaced concrete box bodies 2, 2 of a flexible culvert 1K are connected to each other by solid type flexible rubber 3 (or filled type silicone rubber 10) with both end parts respectively embedded in the respective joint end parts of a pair of concrete box bodies, and filled type silicone rubber 4 of excellent durability and corrosion resistance in a liquid state when filled and having a function of elasticity of rubber after hardened being attached into recessed parts formed of recessed grooves 6, 7 formed on the outer peripheral surface and inner peripheral surface of the respective joint end parts of a pair of concrete box bodies. After the culvert is installed on the footing concrete, the silicone rubber 4 is filled to obtain the prescribed design expansion- eccentric quantity even if the culvert is deformed.

摘要： PROBLEM TO BE SOLVED: To easily construct even a precast concrete shaft having a large diameter excellent in durability and cut-off efficiency as well as high safety and high watertightness with high strength by facilitating the installation/ construction without requiring any skill in junction well or the like of a water conveyance route. SOLUTION: The bottom 6 of a shaft 2 connecting pipe conduits 3 and 4 thereto is formed of a cast-in-place concrete, precast concrete unit length rings 11, 21, 41 and 61 manufactured inside of a haft site or divided into a plurality of pieces and manufactured in a plant are piled up on the bottom of the shaft to form the upper part 5 thereof. A plurality of pieces are connected to each other with bolts by piece joints through sealing compound, at the same time, the upper and lower unit length rings are connected to each other with a bolt by a ring joint through the sealing compound, or both of them are combined with a PC steel bar, and a space between the upper part of the shaft of a plurality of unit length rings and an earth retaining wall is filled with back filling concrete 35.

摘要： PROBLEM TO BE SOLVED: To facilitate construction of a soundproof wall having two-layer structure of a concrete part and an earth part by a method wherein reinforced earth formed of a mixture of sand and continuous yarn is sprayed in a recessed part opened to one surface of a wall body made of concrete and accumulated therein. SOLUTION: Reinforced earth 16 comprised of a mixture wherein sand and a continuous yarn, such as a multifilament untwisted yarn of polyester, are mixed together in a ratio of a dry weight ratio of 0.15-0.2% of the continuous yarn to an amount of sand is sprayed in a plurality of recessed parts 14 in a rectangular shape in plane opened to a slope 18 of a wall body 12 made of concrete approximately in a trapezoidal shape in cross section, and a lower end part 22 of the wall body 12 is arranged below a ground surface 24. A bottom 26 to specify each recessed part 14 paralleling the slope 18 thereof and a plurality of pipes 28 are buried in the wall body 12. A plurality of pipes 30 protruding from the slope 18 are buried below each recessed part 14, and surplus water in the reinforced earth 16 is discharged to the outside of the recessed part 14 through the pipes 28 and 30.
