Background
With the increasing construction of long and large tunnels in the national engineering construction, the development machine is widely adopted in the tunnel construction due to the characteristics of high efficiency, environmental protection and safety. In order to ensure the convenience of later construction, the lining structure generally adopts a separate construction form of an arch wall lining and an inverted arch lining, wherein the inverted arch lining adopts a precast block form, centralized prefabrication production is carried out in a workshop outside a tunnel, the tunnel is transported and then synchronously installed along with tunneling, and concrete is backfilled between the precast block and an excavation surface.
During installation of the precast blocks, after measurement and lofting, the precast blocks need to be fixed by using cushion blocks, then concrete is backfilled on the bottom surfaces of the precast blocks to fix the precast blocks, and the cushion blocks are mostly concrete blocks or iron blocks at present; due to the influence of excavation deviation of the heading machine, gaps between the precast blocks and an excavation surface are not constant, and cushion blocks with different thicknesses are mostly combined for use on site. Sometimes, the height of the combined cushion block is not matched with the gap, so that the installation precision of the prefabricated block is deviated, the field combined cushion block is selected and paired, the efficiency is low, and the follow-up procedures are affected frequently and timely.
