yesterday, at the construction site of Fenghuangshan tunnel in Longkou section of Longkou Yantai Railway, machines roared, slag extractors and sprinklers were operating in an orderly manner, and workers stepped up construction and pushed forward at a speed of nearly 1.6 meters a day. At the exit of the tunnel, the workers are spraying concrete on the arch after the early construction of blasting, slag removal, arch erection, anchor bolting and foot locking. Due to the shallow burial depth and poor surrounding rock of Fenghuangshan tunnel, some areas pass through natural gas pipelines, which is difficult to construct and requires a little blasting. 75 cubic meters of earth and rock need to be cleared for each meter of tunnel excavation, which is a large amount of work. However, the workers have always insisted on high efficiency and high quality to ensure that the project is completed on schedule
