一种隧道工程挤压式二衬混凝土浇筑装置及二衬工法
摘要：
本发明涉及隧道工程技术领域，公开了一种隧道工程挤压式二衬混凝土浇筑装置，包括二衬模板支架和呈环形设置的二衬模板，所述二衬模板支架上设置有若干升降装置，所述升降装置沿隧道周向分布，且升降装置的输出端与二衬模板抵触连接。本发明提供了一种隧道工程挤压式二衬混凝土浇筑装置及浇筑工法。本发明可实现隧道拱部二衬与初衬之间紧密贴合的目的，通过设置二衬模板支架，并在二衬模板支架上设置若干升降装置，使升降装置的输出端与二衬模板抵触，解决了当前现浇混凝土拱部脱空的工程问题。
摘要（英）：

The invention relates to the technical field of tunnel engineering, and discloses an extruded secondary lining concrete pouring device for tunnel engineering. The concrete pouring device comprises a secondary lining template bracket and a secondary lining template arranged annually, and the secondary lining template bracket is provided with a plurality of lifting devices; the lifting devices are distributed in the circumferential direction of a tunnel; and the output ends of the lifting devices are in contact connection with the secondary lining template. The invention provides an extruded secondary lining concrete pouring device for the tunnel engineering, and a pouring construction method. According to the concrete pouring device, the purpose of close fit between a secondary lining and apreliminary lining of a tunnel arch part can be achieved, and through arrangement of the secondary lining template bracket and the multiple lifting devices on the secondary lining template bracket, the output ends of the lifting devices are in contact with the secondary lining template, and the engineering problem that a current cast-in-place concrete arch part is disengaged is solved.
