Claims

[Scope of Claim for Utility Model Registration] (1) In addition to providing a discharge port on the tip side, the supply ports of the lining material and quick hardening agent supply tube are communicated with a cylindrical casing with a screw conveyor inside, and after the casing In a placing device that is provided with a drive source for rotating the screw conveyor on the end side, a plurality of stirring blades are provided on the screw shaft to stir the screw conveyor from approximately the center in the longitudinal direction to the tip. The supply tube for the lining material is connected to the casing with its axis inclined with respect to the axis of the screw conveyor, and the supply port for the quick hardening agent is connected to the supply tube for the quick hardening agent. A hollow annular body is provided which communicates with the injection port of the cylinder, and a hole penetrating from the hollow interior of the annular body into the casing is formed, and the lining material is introduced into the casting space via a piston sliding device. A mixing and pouring device for tunnel lining materials. (2) A mixing and casting device for tunnel lining materials, characterized in that the supply port for the quick hardening agent is located closer to the discharge port of the casing than the supply port for the lining material. (3) The tunnel according to claim 1 or claim 2, characterized in that the stirring blades of the stirring section are formed on the locus of the screw blades and have substantially the same curved surface as the screw blades. Lining material mixing and pouring equipment.
