Shantui: The Mainstay of the Construction of Shenzhen-Zhongshan Bridge

▌June 30，The world's first episode“Bridge、Island、Tunnel、Underwater communication”The Shenzhen-Medium Passage, a cross-sea cluster project, was officially opened for trial operation.。At this point，The east and west banks of the Pearl River Estuary“Shenzhen, Dongguan and Huizhou”And“Pearl River”The two urban agglomerations have been directly connected across the sea.，Deep in“Half-hour life circle”、The Greater Bay Area“One hour life circle”Become a reality。

▌For offshore bridge and tunnel construction scenario，The offshore platform concrete mixing station specially developed by Shantui has become a necessary tool for concrete production of the project.。As early as 2018，Shan Tui Duo SuitE3R-090、E3R-120、E3R-180 offshore platform concrete mixing stations have successively participated in the construction of Shenzhen-Medium Passage，Provide high quality concrete for bridge construction of Shenzhen-Medium Passage。

▌The layout of Shantui offshore platform concrete mixing station fully considers the construction cost of offshore platform.，Optimize the feeding path，Achieve a 20% reduction in floor space%；Container-type structure is adopted、The powder silos are interconnected、The main bearing points are arranged vertically and linearly，It provides convenience for the construction of platform pile foundation，At the same time, it greatly enhances the wind resistance of offshore construction process.。

▌For the convenience of offshore operation，Shantui Concrete Station is also specially equipped with a large amount of steel structure three-dimensional aggregate bin without foundation.，It can meet the maximum amount required for continuous pouring of concrete at one time.；Movable cover of aggregate bin with special structures，Ffectively prevent rainwater from entering that storage bin，Guarantee the accuracy of material proportioning；Coarse and fine weighing devices shall be provided for all material metering.，Further guarantee the measurement accuracy 99%Above，Achieve full traceability of aggregate flow direction。

▌In order to ensure the rigor of construction，Display the temperature of raw materials in the concrete mixing station of Shantui offshore platform、Sand moisture content on-line monitoring、The functions of powder and admixture storage and concrete temperature collection are integrated，It provides a guarantee for all kinds of data acquisition and monitoring on site.。

▌As an ordinary participant，Shantui has witnessed the trials and hardships of the Shenzhen-Zhongshan Bridge in the past seven years.。Many innovative technological achievements of the Shenzhen-Medium Passage have been demonstrated.“Made in China”The surging power of，It also shows the strength and strength of our country to speed up the construction of a strong transportation country.，Add a new chapter to the construction of the world's cross-sea passage project。
