Patent number: 4913587Abstract: A form structure for making a primary concrete covering wall on the surface of the wall of a tunnel which extends behind a shield type tunnel excavator advanced, wherein a form structure for casting concrete to make the covering wall is assembled with a plurality of arcuate form assemblies respectively including form segments and timbering members for reinforcing the cast and set concrete. The form segments of each assembly are detachably coupled to the timbering members. The form structure is disassembled after the cast concrete is set by detaching the form segments of the respective assemblies from the timbering members to leave the members on the primary covering wall of the set concrete, whereby the primary covering wall can be held in stable state simultaneously with completion of the primary covering wall on the tunnel wall surface.Type: GrantFiled: July 29, 1988Date of Patent: April 3, 1990Assignee: Tekken Construction Co., Ltd.Inventors: Fumitaka Kumai, Yoshihiro Takano
