Embodiment Construction
[0049] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0050] like figure 1 and figure 2 As shown, the method includes:
[0051] Step 1. Clean up the gravel and debris in the construction site, level the construction site, and compact and harden the construction site.
[0052] Step 2. Design the position of the longitudinal probe hole 2 along the tunnel centerline 1. The diameter of the longitudinal probe hole 2 is φ800mm, the hole distance is 750mm, and the occlusal width is 50mm. By analogy, the position of the horizontal clearance hole 3 is confirmed according to the position of the longitudinal probe hole 2. The diameter of the horizontal clearance hole 3 is φ800 mm, and the hole distance is 1300 mm. out), and add a sub-serial number on the basis of the number of the longitudinal probe hole 2 as the number of the horizontal clearance hole 3. 2#, 1-3#, 1-4#, and so on, are used to...
