あった。For example, as shown in FIG. 10, the conventional method of connecting two concrete cylindrical members 1.1 by arranging a band-shaped flexible connecting member 2 between the inner circumferential surfaces of opposing ends is conventional. This method involves inserting bolts 3 into bolt holes drilled on both sides of the connecting member 2, and screwing the ends of the bolts into embedded nuts 4 opened on the inner surface of the box culvert to fasten and secure the bolts. This conventional method has the drawback that the water stop surface is lost by drilling bolt holes in the connecting material, and if the embedded nuts and bolt holes do not match well, the water stop performance is reduced. There were problems such as the flexible connecting material being exposed on the inner circumferential surface of the culvert, causing failure and the connecting material being easily damaged.Also, when installing or replacing the connecting material, many bolts were inserted into the bolt holes. Insert the embedded nut into the
It requires a lot of time and effort to screw into the screw holes of the
This had the disadvantage that it was extremely difficult for people to enter and work inside.

端部外周面に周方向に長い押材で押圧し固定しである。This box culvert has the above structure, and the opposing ends of two cylindrical members are connected by a band-shaped flexible connecting material, and both side edges of the connecting material are the outer peripheries of the opposing ends of the cylindrical members. It is fixed by pressing on the surface with a circumferentially long pusher.

を発現できる。Therefore, (1) the strain applied to the box culvert is absorbed by the deformation of the connecting material between the two members, and the strain stress acting between the box culverts can be alleviated. ■The connecting material does not require drilling holes such as bolt holes, and is fixed by pressing with a continuous long pusher material, so there is no defective part and high water-stopping properties can be achieved.

る場合に比べ位置合せが容易で作業性が向上する。■Since the connecting material is fixed to the outer peripheral surface of the end of the cylindrical member, it can be fixed from the outside surface even if it is a small-diameter box culvert. Damage to the connecting material can be reduced. In addition, when installing the connecting material, the bolt inserted through the bolt hole of the pusher can be directly screwed into the embedded nut, making positioning easier than when inserting the bolt into the bolt hole of the connecting material. Improves work efficiency.

ある。In addition, if the bolt hole 15 is made into a long hole as in the pusher in the embodiment, the tip of the bolt 9 inserted through the bolt hole 15 can be easily aligned with the embedded nut 4, and the workability of fixing the connecting member 2 is improved. can be made even higher. Furthermore, it is preferable to cover the outer peripheral surface of the connecting portion with a steel collar or the like to protect the connecting member.

間の緩衝に作用するほか、端面間に挟まれて、止水性を
高め、三次止水の作用を発揮する。If a T-shaped cross section is used as the connecting member and the central piece is positioned between the opposing end faces of the cylindrical member, the central piece will not only act as a buffer between the end faces, but also be sandwiched between the end faces to provide water-stopping properties. , and exhibits a tertiary water stop effect.

折曲により生じる連結材の歪発生を防止できる。When a straight part connecting member and an L-shaped or T-shaped corner connecting member are joined between their ends to form a connecting member, the end of the cylindrical member with a square cross section is attached at a right angle to the outer circumferential corner part, and a pusher member is attached. Since it can be suppressed and fixed, it is easier to work with than when straight connecting materials are bent and attached along the outer circumferential surface of the corner.
It is possible to prevent distortion of the connecting material caused by bending.

。The box culvert according to the present invention can absorb strain caused by unevenness at the connecting member portion of the two cylindrical members, and can prevent the box culvert structure from being destroyed. The connecting material has high water-stop properties and is difficult to damage. Furthermore, the workability of attaching the connecting member is excellent, and there is no problem in attaching it even when the diameter is small.
