一种用于围护桩段明挖隧道的拱部外模台车
摘要：
一种用于围护桩段明挖隧道的拱部外模台车，属于隧道施工技术领域，可解决现有施工过程中出现的拱部外模上浮、偏移的问题，以及施工效率低，接缝多，外观效果差，且拉杆孔渗水风险高的问题，包括门架横梁、门架纵梁、门架弧形斜支撑和门架支腿，移动组件包括横移架横梁、横移架纵梁、液压千斤顶Ⅰ和液压千斤顶Ⅱ，弧形模板的两端分别位于隧道边墙的顶部，弧形模板通过若干模板支撑丝杆和门架弧形斜支撑连接，门架横梁的两端分别通过横梁支撑丝杆与隧道的围护桩连接，门架纵梁与门架支腿的一端连接，门架弧形斜支撑的一端与门架横梁连接，门架支腿的一端和门架横梁连接。本实用新型施工效率高，施工安全。
摘要（英）：

The utility model provides a hunch portion external mold platform truck for retaining pile section open trench tunnel, belong to tunnel construction technical field, can solve the hunch portion external mold come -up that appears in the present work progress, the problem of skew, and the efficiency of construction is low, the seam is many, the outward appearance effect is poor, and the high problem of draw bar infiltration risk, including the portal crossbeam, the portal longeron, portal arc bearing diagonal and portal landing leg, it includes the transverse moving rack crossbeam to remove thesubassembly, the transverse moving rack longeron, hydraulic jack I and hydraulic jack II, arc formwork's both ends are located tunnel side wall's top respectively, arc formwork connects through a plurality of formwork support lead screws and portal arc bearing diagonal, the both ends of portal crossbeam are connected through the retaining pile of crossbeam support lead screw with the tunnel respectively, the portal longeron is connected with the one end of portal landing leg, the one end and the portal crossbeam of portal arc bearing diagonal are connected, the one end and the portal crossbeam of portal landing leg are connected. The utility model discloses the efficiency of construction is high, construction safety.
