The roof of Yantian Food Street Station of Shenzhen Metro Line 8 Phase II project in the first working area has been completed successfully

On August 18, with the completion of the last roof pouring, shenzhen Metro Line 8 Phase II project Yantian Food Street station has been completed. This is another important project node after the double line of yanbei shield tunnel. So far, the construction task of "two stations and three sections" of the project has been successfully completed: "two stations" (Beishandao Station, Yantian Shijie Station) and "one section" (Yanbei shield tunnel section), which also marks the completion of the main construction of the station.

It is reported that Yantian Shijie station for the underground two layer island platform station, the structural form of the underground two layer single column double span closed frame structure, the total length of the station 210.8m, the effective platform width of 11m, three entrances, the south side of the reserved business district, the station set up two groups of wind pavilion, using open excavation method construction.

Due to the small construction site, close distance from surrounding buildings, and numerous underground pipelines, it is necessary to carry out trench construction in breezed rock strata during the process. Besides, the thickness and characteristics of the strata change greatly, and the underlying bedrock is complex and lithologic, making the construction extremely difficult. To this, since the start, combined with actual project group, overall consideration, in view of the difficult point of construction, on the premise of security, technology as the leading, optimizing the process method, reasonable arrangement of construction process, take the "wall", measures such as foundation pit in the middle of partition wall, solve the station traffic impact caused by seafood street space narrow, palisade structure can't in full swing, The construction difficulties of "high rock surface" of the station were successfully broken through to ensure the rapid progress of the main construction of the station. At the same time, by setting automatic mobile protective greenhouse, while ensuring the safety of blasting construction, it achieves green environmental protection, reduces the influence of weather factors, and realizes continuous operation.

In addition, on the premise of strictly completes the epidemic prevention and control work, the project team make full use of the site safety experience training education center, in the form of "immersion" safety training education, and organize to carry out the blasting, fire, typhoon, flood, such as lifting field drill, the safety management task decomposition to the finest point, security responsibility to implement, It further improves the safety awareness of operators, ensures the safe and orderly construction of the station, and realizes the balance and control of quality, safety and progress.
