PROBLEM TO BE SOLVED: To provide a box culvert in which a lubricant for pipe jacking injected outside each side face of the box culvert is easy to creep around a corner section, a cut-off rubber ring has high adhesion and correction in the case of rolling can be conducted easily.;SOLUTION: The box culvert has a cylindrical main body section 3 in which a passage hole 7 is formed on the inside surrounded by four side faces 5 and a cross section in a rectangular plane in the extending direction of the passage hole 7 is formed in an approximately rectangular shape. Lubricant injection holes 9 for injecting the lubricant for pipe jacking to the surfaces of the side faces 5 from the passage hole 7 side are formed to each of the four side faces 5, and the outer edges of the corner sections 13 formed among the four side faces 5 are formed substantially in an arcuate shape.;COPYRIGHT: (C)2001,JPO
