Claims

[Scope of Claim for Utility Model Registration] 1. In a cylindrical socket fixed to a grout injection hole of a segment forming a unit wall plate in the circumferential direction of a shield pipe for construction work, a valve seat forming a stepped portion of the inner hole of the socket; a support member that is penetrated in the thickness direction of the valve seat and whose one end in the penetration direction is integrated with the valve seat; and a support member that is inserted into the support member and slides between a closed position and an open position of the socket inner hole. a dynamically displaceable valve body; one end of the valve body is in contact with the surface of the valve body on which the grout is injected; the other end is fixed by the support member; An elastic body that biases toward a closed position, wherein the valve body opens the inner hole of the socket when a pressure greater than the bias of the elastic body is applied. 2. In a cylindrical socket fixedly installed in a grout injection hole of a segment forming a unit wall plate in the circumferential direction of a shield pipe for construction work, a valve seat forming a stepped part of the inner hole of the socket, and a valve seat integrated with the above valve seat. The socket has a support shaft that fits into the support shaft, and a bearing part that fits into the support shaft at one end, and is formed into a semicircle with a size that bisects the inner hole of the socket, and the inner hole can be in a closed state or an open state. a valve plate that is displaceable in the closed position; and a valve plate that is fitted onto the support shaft and comes into contact with a surface of the valve plate on the side where grout is injected, and provides an urging force that permanently maintains the valve plate in the closed position. An elastic body, wherein the valve plate is switched to an open position when a pressure greater than the biasing force of the elastic body is applied.
