制造具有热塑性阻隔层的丘宾筒片的方法
Abstract:
本发明的核心是制造由混凝土构成的丘宾筒片的方法，所述丘宾筒片用于加衬隧道，特别是交通隧道，其中丘宾筒片(1)具有凸形弯曲的外表面(2)和与外表面(2)相对的凹形弯曲的内表面(3)，所述方法包括以下步骤：a)在外表面(2)上施加具有热熔粘合剂层(5)和热塑性阻隔层(6)的膜(4)，并进一步将该膜至少部分地施加在丘宾筒片外侧面(7,8)的所有的面向外表面(2)的侧面上，其中所述热熔粘合剂层(5)面向丘宾筒片(1)；b)导入热熔化热熔粘合剂层(5)；c)冷却热熔粘合剂层(5)并在膜(4)和丘宾筒片(1)之间形成粘接复合体。
Abstract(English):

The invention relates to a method for producing a lining segment made of concrete for lining a tunnel, in particular a traffic tunnel. The lining segment (1) has a convexly curved exterior (2) and a concavely curved interior (3) opposite the exterior (2). The method consists of the following steps; of a) placing a membrane (4) having a hot-melt adhesive layer (5) and a thermoplastic barrier layer (6) on the exterior (2) and additionally on each lining segment outer surface (7, 8) face facing the exterior (2), said hot-melt adhesive layer (5) facing the lining segment (1); b) supplying heat while melting the hot-melt adhesive layer (5); and c) cooling the hot-melt adhesive layer (5) while forming an adhesive bond between the membrane (4) and the lining segment (1).
