隧道路面基层混凝土由拌合站集中拌制，采用混凝土罐车运输至隧道使用，搅拌

The concrete on the base of the tunnel pavement is centrally mixed by the mixing station and transported to the tunnel using a concrete tank truck. The drop of the unloading and discharging of the mixing station should not exceed 2m. During the transportation process, it is necessary to ensure that there is no slurry leakage, no drying, and no segregation. When discharging, try not to accumulate too high, and the discharging height should not exceed 1.5m.

Tunnel road grass-roots concrete by the mixing station centralized mixing, the use of concrete tanker transport to the tunnel use, mixing station leakage drop difference should not be greater than 2m. In the transport process to ensure that no leakage, constant dry, do not separate analysis, discharge as far as possible do not pile up too high, discharge height should not exceed 1.5m.

The base course concrete of the tunnel pavement is mixed by the mixing station in a centralized way and transported to the tunnel by the concrete tank truck. The leakage and discharge drop of the mixing station shall not be more than 2m. In the process of transportation, it is necessary to ensure that there is no leakage of slurry, no drying and no segregation. When unloading, try not to pile up too high, and the unloading height should not exceed 1.5m 。<br>
