Embodiment Construction
[0069] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.
[0070] Such as Figures 1 to 18 As shown, a construction method for an overall straight mid-wall type double-arch tunnel comprises the following steps:
[0071] Ⅰ. Excavate the intermediate pilot tunnel according to the design requirements, and carry out the initial support of the intermediate pilot tunnel;
[0072] Step 1: Excavate the upper steps of the pilot tunnel according to the design requirements 1, carry out the initial support of the pilot tunnel 600;
[0073] Step 2: Excavate the lower steps of the pilot tunnel according to the design requirements 2. Perform the initial support of the pilot tunnel 600;
[0074] Ⅱ. The middle wall of the double-arch tunnel is constructed in the middle pilot tunnel, and there is a hollow on the top of the middle wall between the top of the middle wall and the top wall of the middle pilot tunnel;...
