前後進用のジヤツキ、１２は支持板である。The arch-shaped culvert 1 made of concrete has a bottom slab portion 2, side slab portions 3a, 3b, and an arcuate upper wall portion 4.
The outer corners on both sides are formed into curved shapes 5a and 5b. A blade opening frame 7 formed in the same shape as the culvert is attached by fitting a backing plate 6t to the front surface of the arch-shaped culvert l which becomes the head. The frame has vertical partition plates ga, 8b and a shelf plate 9 on the intermediate portion, and an intermediate deck 10t which moves forward and backward is attached thereto. 11 is a jack for forward and backward movement, and 12 is a support plate.
