Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application 1] The present invention relates to a joint structure for a waterway formed by connecting waterway construction blocks such as secondary concrete products.

[Prior art] As a conventional waterway joint structure, for example, the Japanese Patent Publication No. 55-41
There is one disclosed in Publication No. 64. In this joint structure, the nut body is embedded and fixed at the end of the waterway construction block.
With the ends of the waterway construction blocks butted against each other, screw a bolt passing through the small diameter hole at one end of the communication plate into the nut body of one waterway construction block, and then insert the bolt through the oblong hole at the other end of the communication plate. By screwing another bolt passing through the eccentric shaft hole of the eccentric seat plate into the nut body of the other waterway construction block, the left and right adjacent waterway construction blocks are joined.

[Problems to be Solved by the Invention] However, in such a waterway joint structure, the threaded tightening of the bolt may be weakened due to a construction error, or the gap between the gaps between the joint members may be shortened due to a manufacturing error. When the size exceeds the specified value, if an unexpected large L loading load is applied on weak ground, the block row may not be able to resist this and may flex and sink. It is not possible to have a very long span at the joints of the structure, and in soft ground, the number of support piles must be increased, and supports must be installed for each PI, that is, for each joint. There wasn't.

Therefore, the purpose of the present invention is to
In addition, even if the gap between the joints is larger than the predetermined value S, a moderate pressing force will be applied between the joint ends of each waterway construction block, so that unexpected large Even when a load is applied, the blow 7 row does not bend, and
