Abstract

The invention provides a positioning device for mounting a tunnel two-lining butterfly waterstop. The positioning device comprises a first end mold, a second end mold and multiple side wing positioning devices, wherein the first end mold and the second end mold are arranged in a butt joint manner, and a butterfly waterstop is placed between the first end mold and the second end mold; a free end ofthe first end mold is fixed to a two-lining trolley mold plate; a free end of the first end mold is fixed to tunnel primary support concentrate; and the multiple side wing positioning devices are fixed to side wings of the butterfly waterstop at intervals. The positioning device can effectively control the space position and state of the waterstop in engineering solids; and penetration of waterstop ribs by nails is not required and the overall sealing performance of the waterstop is guaranteed.

Description

technical field [0001] The invention belongs to the field of tunnel waterproofing and drainage, and in particular relates to an installation and positioning device for a butterfly-shaped waterstop on the second lining of a tunnel. Background technique [0002] Tunnel waterstop installation is a routine process in the construction of composite lining tunnels. The quality of waterstop installation directly affects the waterproof quality of tunnels. For the installation of the second lining butterfly waterstop, the current conventional method is to press the waterstop to the end formwork of the lining section from the side (the side of the first lining section), so that the waterstop on the side of the lining section after pouring The deformation is close to the end formwork, and the waterstop is fixed point by point from the rib interval with iron nails; the lining section is first poured and maintained for a period of time, and then the formwork is removed, and the previously...
