Construction of Gaoligongshan Tunnel of Dali-Ruili Railway under Extreme Working Conditions by Promoting Jianyou Concrete Mixing Station Deep Tunnel

Recently，The longest railway mountain tunnel in Asia、Darui Railway Throat Control Project，Construction site of Gaoligongshan Tunnel，Shantui Jianyou is specially customized for shaft construction.E5R-The 180 concrete mixing station is busy day and night.，It is the longest auxiliary tunnel of railway tunnel in China.——Gaoligongshan Tunnel 764m Shaft Auxiliary Tunnel Construction Escort。

In order to ensure the construction of the shaft，The R & D team of Shantui Jianyou fully considers the restrictions of underground construction and the homogeneity of concrete mixing.、High efficiency and the like，Overall consideration of height and structure of Concrete Mixing Plant，Adjust powder metering and conveying height，Improve the secondary conveying efficiency，Solve shaft construction problems with professional technology，The feasibility of the scheme is effectively guaranteed.、Accurate measurement、And that construction is efficient。This Concrete Mixing Plant has continuous material conveying、Shorter weighing cycle、More accurate measurement accuracy，In particular to a patented arc discharge door.，Satisfy the secondary feeding and stirring proces，Guarantee the strict proportion and delivery time of material delivery；Professional concrete mixing machine，More uniform mixing of concrete raw materials，More reliable for field use。

During the installation and adjustment，Shantui Jianyou's after-sales service team gives full play to its hard work.、Struggle hard、The spirit of climbing the peak forever，Even if the water on the ground is knee-deep，It also insists on the erection and installation of the concrete mixing station.。They travel day and night，More than 12 hours of deep well operation every day，It took only 7 days to complete the erection and installation of the concrete mixing station.，Ensure the progress of the project efficiently，It provides a guarantee for the project.，It shows the service quality and installation speed of Shantui Jianyou.。

With excellent quality，Shantui Jianyou Concrete Mixing Station has been applied to the Qinghai-Xizang Plateau at an altitude of more than 4000 meters for many times.、Extreme construction environments such as the Pacific Ocean with strong winds and high waves，And has been affirmed by customers in the industry.。This time, it continues to be applied to deep wells more than 700 meters underground.，It also fully demonstrates the extreme environmental adaptability and excellent technical strength of Shantui Jianyou Concrete Mixing Station.，It explains the heart of Shantui Jianyou to help the national infrastructure construction.。

It is reported that，Darui Railway is“The Belt and Road”It is an important part of the western line of the Pan-Asian Railway and the China-Myanmar International Corridor.，It is the China-Myanmar International Railway in China.“The last paragraph”。After its completion, it will end the history of no railway in western Yunnan.，To promote exchanges and cooperation between China and Southeast Asian and South Asian countries，Reshape“Ancient Silk Road in the south”Brilliance plays a very important role.。
