Embodiment Construction
[0024] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0025] Such as Figure 1 to Figure 4 Shown is a preferred embodiment of the method for speeding up the construction of multi-arch tunnels according to the present invention. In the construction of multi-arch tunnels, firstly, the middle pilot tunnel 1 is pre-supported by using double rows of leading small conduits 1-1. Carry out the excavation of middle pilot tunnel 1 next, in the excavation process of described middle pilot tunnel 1, carry out the construction of the cover arch of left main tunnel 2, right main tunnel 3 and middle pilot tunnel 1 and long pipe shed simultaneously, in During the excavation of the pilot tunnel 1 in the first half, the waste sla...
