UNIVERSAL JOINT FOR CULVERT CONNECTED BODY, AND CULVERT CONNECTED BODY
PROBLEM TO BE SOLVED: To provide a universal joint for a culvert connected body and a culvert connected body provided with the universal joint that minimize a length of the universal joint part while securing a function and durability as a culvert, at the same time improving efficiency of installation work for the overall culvert connected body by increasing flexibility of a bellows-like part.SOLUTION: In universal joints (3, 6, 7, 8) of a culvert connected body (1) used at a bent location of the culvert connected body (1) installed by fitting in a ditch and connecting each other, a bellows-like part (31) of a corrugated shape is formed by an elastic rubber body, and notch grooves (M1, M2) are formed on a surface layer of an inner surface and/or an outer surface of the bellows-like part 31.SELECTED DRAWING: Figure 9
【課題】溝渠としての機能及び耐久性を確保しつつ自在継手部分を極力短くするとともに、蛇腹状部分の可撓性を向上させて溝渠連結体全体の設置作業の作業効率を向上させることができる溝渠連結体の自在継手及びそれを備えた溝渠連結体を提供する。【解決手段】地溝に嵌め込んで連結しながら敷設される溝渠連結体（１）の屈曲箇所に用いられる溝渠連結体（１）の自在継手（３、６、７、８）において、コルゲート状に形成されたゴム弾性体の蛇腹状部（３１）を設け、この蛇腹状部３１の内面及び／又は外面の表層に切欠き溝（Ｍ１、Ｍ２）を形成する。【選択図】図９
