Floating slab ballast bed foundation surface plastering device and working method
The invention provides a floating slab ballast bed foundation surface plastering device and a working method, and relates to the technical field of tunnel foundation construction, the floating slab ballast bed foundation surface plastering device comprises a guide frame and a plastering plate, the two ends of the guide frame are respectively provided with a sliding rail along the inner wall of a duct piece, and the sliding rails are matched with sliding supports hinged to the guide frame so as to maintain the guide frame to be parallel to a ballast bed foundation; the plastering plate is connected with a suspender, the suspender is in sliding fit with a guide groove preset in the guide frame, the plane where the plastering plate is located is parallel to a ballast bed foundation, and the plastering plate is used for horizontally moving in the direction perpendicular to the axis of a tunnel. In order to solve the problem that an existing trowelling tool cannot meet the leveling requirement of a ballast bed foundation, a sliding rail and a sliding support are arranged to serve as a structure for bearing a guide frame, the posture of the guide frame is adjusted according to the inclination of the ballast bed foundation at different positions, the plane where a trowelling plate is located is parallel to the ballast bed foundation, and the trowelling plate is driven to transversely move along a tunnel when being driven to move; the surface of the ballast bed foundation is scraped to achieve trowelling, and the installation requirement of the assembly type ballast bed slab is met.
本发明提供一种浮置板道床基础表面抹灰装置及工作方法，涉及隧道基础施工技术领域，包括导向框架和抹灰板，导向框架两端分别设有沿管片内壁的滑轨，滑轨上配合有与导向框架铰接的滑动支座，以维持导向框架与道床基础平行；抹灰板连接吊杆，吊杆滑动配合导向框架上预设的导向槽，抹灰板所在平面与道床基础平行，抹灰板用于沿垂直于隧道轴线方向平动；针对目前抹平工具难以满足道床基础找平需求的问题，通过布置滑轨和滑动支座作为承载导向框架的结构，根据不同位置道床基础的倾斜度调节导向框架的姿态，使抹灰板所在平面与道床基础平行，驱动抹灰板移动时沿隧道横向平动，刮动道床基础表面实现抹平，满足装配式道床板的安装需求。
