Hole entering method for bias pressure tunnel
The invention provides an unsymmetrical pressure tunnel hole entering method, and relates to the technical field of tunnel construction. The unsymmetrical pressure tunnel entering method comprises the following steps that a supporting structure is arranged at a slope with a preset height, and a first arch frame is arranged between the top of the supporting structure and the slope; the slope below the first arch frame is excavated, so that a tunnel is jointly defined by the supporting structure, the first arch frame and the slope; and the first arch frame is subjected to layer sealing treatment. Construction is simpler and more convenient, roof collapse, collapse and other phenomena can be prevented in the construction process, the construction safety is improved, and disturbance to the surface layer of a slope mountain can be reduced.
本发明提供了一种偏压隧道进洞方法，涉及隧道施工技术领域。偏压隧道进洞方法包括以下步骤：在预设高度的斜坡处设置支撑结构，并在支撑结构的顶部和斜坡的之间设置第一拱架；挖除第一拱架下方的斜坡，以使支撑结构、第一拱架以及斜坡共同围成隧道；对第一拱架进行封层处理。不仅施工更加简单方便，也能够防止施工中发生冒顶、坍塌等现象，提高了施工的安全性，还能够降低对斜坡山体表层扰动。
