    • PROBLEM TO BE SOLVED: To reduce the cross section of a wall body, a girder material or the like and improve the stability or the like in a permeable check dam securing the sand settling capacity in a debris flow by providing the girder materials in an opening part. SOLUTION: The opening part 10 between the wall bodies 2 is set twice or more as large as the maximum flowing-down gravel diameter, and a plurality of the girder materials 3 are vertically disposed at intervals of 1.5 times or less the size of the maximum flowing-down gravel diameter in the downstream side of the opening part 10 and slantly disposed to position in an upstream side as getting vertically upward. The sand gravel in the debris flow is led between the wall bodies and stopped by the girder materials, the sand gravel is settled in a space in the upstream side of the opening part, and the sand settling shape is formed into a gentle slope to reduce a settling sand pressure applied to the girder material. The girder material 3 is detachably attached by embedding a sheath pipe into a hole formed in a wall body and inserting the end of the girder material joined through a joining part into the sheath pipe.

    • PROBLEM TO BE SOLVED: To provide a vibration damping device and an erecting member superior in vibration damping performance, capable of effectively coping with vibration with a frequency varying over a wide range from a low frequency up to a high frequency regardless of the direction of the vibration. SOLUTION: This vibration damping device 1 is composed of a vertical hollow body 10 suspending a suspending member inside. The vibration damping device and the erecting member superior in vibration damping performance are characterized in that the axis of the suspending member coincides with the axis of the vertical hollow body, and the suspending member is composed of a linear upper suspending member such as a wire 9 and a lower suspending member formed by connecting a plurality of metallic bodies 8. In the erecting member superior in vibration damping performance, there are a case of imparting the vibration damping performance by installing the vibration damping device outside or inside the erecting member, and a case of imparting the vibration damping performance to the erecting member itself by directly suspending the suspending member inside the vertical hollow body being the erecting member.

    • PROBLEM TO BE SOLVED: To provide a sound insulating wall for an expansion/contraction section, which has a structure enabling the sound-insulating wall itself to be expanded/contracted depending on the expansion/contraction of a bridge section. SOLUTION: In this sound insulating wall for the expansion/contraction section of the bridge section, an expansion joint section T of the bridge section is positioned between H-shaped cross-section supports 1 and 1 which are erected at each predetermined interval in the longitudinal direction of the bridge section; and a plurality of vertical steps of sound insulating panels are mounted between the supports 1 and 1 adjacent to each other with the joint section T in between. The sound insulating panel is composed of three panel members which are connected together in such a manner as to be mutually expandable/contractible and slidable in the longitudinal direction of the bridge section; the two panel members on both sides are fixed to the adjacent panel members 1 and 1, respectively; and the intermediate panel member is slidably supported on both the panel members.
