Claims

[Scope of Claim for Utility Model Registration] A saddle portion of a block member having a concave close contact placement portion on the lower surface that is removably placed in close contact with a fresh concrete delivery pipe, and a lower end of the block member that is movable up and down into an insertion hole of the saddle portion. A valve body consisting of a group of dam bars that are inserted through and engaged with the portal frame at the upper part and arranged in parallel at arbitrary pitches, and the upper end is removably connected to both ends of the saddle part. and a pair of opposing adhesive bands which are attached to the outer periphery of the fresh concrete delivery pipe and whose lower ends are opposite to each other, and whose lower ends can be freely connected and opened; 1. A stop valve for a fresh concrete delivery pipe, characterized in that the stop valve has a structure including a raised and lowered mechanism for the damming bar group consisting of a formed rack and a pinion provided in the saddle portion and paired with the rack.
