Railway tunnel center ditch cutting construction device and method
The invention relates to a railway tunnel center ditch cutting device and a construction method, and belongs to the technical field of railway tunnel center ditch excavation, and a chain-shaped cutting lock sequentially penetrates through a power device, a tensioning device, a guide wheel and a rotating wheel to form a ring. The chain-shaped cutting rigging is driven by the power device, the guide column extends downwards to the designed depth of the tunnel center ditch, and hard rock is deeply cut to the designed depth; the chain-shaped cutting rigging is placed at the bottom of the cutting seam at the end away from the free face, and the bottom is horizontally cut; and the cutting body is crushed, excavated and discarded by a machine. The method has the beneficial effects that the geometric dimension required by excavation of the central ditch can be more accurately controlled according to design requirements, the construction efficiency can be improved, and unnecessary waste is avoided.
本发明涉及一种铁路隧道中心水沟切割装置及施工方法，属于铁路隧道中心水沟开挖技术领域，链形切割锁具依次穿过动力装置、张紧装置、导向轮和转轮，围成环形。通过动力装置驱动链形切割索具，通过导向柱向下伸张到隧道中心水沟设计深度，对硬岩进行深层切割至设计深度；将链形切割索具安放于远离临空面一端切割缝的底部，对底部进行水平切割；用机械将切割体破碎、挖除并外弃。本发明的有益效果是：便于更加精准地按设计要求控制开挖中心水沟所需的几何尺寸，有利于提高施工效率，避免不必要的浪费。
