发明名称 INJECTING HOSE APPARATUS FOR CONCRETE CONSTRUCTION
摘要 PROBLEM TO BE SOLVED: To provide an injecting hose apparatus for a concrete construction, which makes an injecting liquid penetrate surely into a placing joint face to cut off water even after post-cast concrete is laid. SOLUTION: The filling hose apparatus comprises a hose body 1 having the outer wall surface 1a on which a number of check valves lip pieces 3, which are formed via sloped cutting faces 2, are formed integrally, and a cylindrical net 4, which is fitted at the outside of the hose body 1 to keep the lip pieces 3 closed when the filling liquid 11 is not filled into the hose body. A small hole 5 drilled in the radial direction to reach the hole 1b of the hose body 1 is formed on a remaining inner diameter side wall 1c corresponding to each lip piece 3 integrally formed via the sloped cutting face 2, so that pressure inside the hole 1b is applied to each lip piece 3.
