Hang it, align the center marks of the invert block and the bottom plate (y), and gently lower it onto the bottom plate (y) inside the manhole (5). Then, adjust with a crowbar so that the gap between the inner wall of the manhole (H) and the outside diameter of the invert block is constant, and use a crowbar to make fine adjustments so that each tube core and the mouth core of the block side match.

る。(Effects of the Invention) The invert block of the present invention is a factory product that has been carefully managed, so there is no variation, the finish is clean, the installation is accurate with adjustment bolts, and the finishing work is easy, so it can be done easily by plasterers, etc. It can be constructed by ordinary workers, not special workers. Furthermore, unlike conventional on-site construction, there is no floating or peeling of the surface mortar, and even if there is a small leak, the construction can be completed and water can be passed immediately, which shortens the construction period and reduces construction costs. This is a new and invented product that has many effects, including being able to be used for manholes.
