On the riverside of Anhui Province, a great project has been completed-the Wuhu Longwan Yangtze River Tunnel. A major artery of people's livelihood transportation, which crosses the north and south of the Yangtze River and connects the future of the city, is officially opened to traffic today.
This super project, which has attracted much public attention, not only witnesses the surging pace of Wuhu's "cross-river development and eastward acceleration", but also bears the efforts and sweat of thousands of builders.
In this engineering epic, there is an "invisible force" that has always been silently supported-that is, high-quality cement products from conch. Conch Cement , with its excellent quality, reliable supply and sincere service, has provided solid support for the construction of the tunnel and built this long underground dragon across the Yangtze River.

01. Outstanding Contribution
of Conch Cement Since October 2017, Wuhu Baimashan Cement Plant, a subsidiary of Conch Group, has been responsible for supplying Wuhu Big Shield Co., Ltd. of China Railway 14th Bureau Group. Cement is mainly used for the prefabrication of all segments of the two shield tunnels. These "invisible components" will become the "skeleton" of the tunnel forever.
Conch Cement has supplied about 112,000 tons of segment PII52.5 bulk cement and 34,900 tons of on-site piling PO42.5 bulk cement. In this supply cycle of several years, Conch Cement has always been a stable and continuous supply, escorting the smooth progress of tunnel construction.
Facing the continuous demand of tunnel construction, the factory continues to serve the national key projects such as Wuhu Yangtze River Third Bridge and Fuqing Nuclear Power Station, establishes the whole process tracking mechanism of "shipping-transportation-site" for tunnel projects, and closely links the sales office with the 14th Bureau of China Railway, the construction party, actively urges the transport units to carry out vehicle dispatching and open green. Priority should be given to ensuring the supply of cement for key projects and ensuring the timely supply of cement. The tunnel project of Baimashan Cement
Plant of Conch Group, which guarantees the supply of cement
for the prefabricated components of the river-crossing tunnel, has extremely strict requirements on the performance of cement. The PII52.5 bulk cement supplied by Conch Cement, with its excellent performance, perfectly meets the engineering needs. In the prefabrication of large shield segment, this kind of cement can meet the requirements of crack resistance and durability of shield segment, and provide a solid material basis for the permanent lining structure of the tunnel. From raw material selection, process quality control to fine production operation, Conch Cement strictly controls the whole process to ensure stable and reliable cement performance, so that the tunnel can be rock-solid in the face of water and soil pressure and load.
"It is not to send a ton of cement to the component factory to complete the task." The person in charge of Conch Cement said that the real guarantee is to make every segment stand the test of time and pressure.
Conch Cement cooperates closely with Wuhu Shield Machine Co., Ltd. of China Railway 14th Bureau Group to provide precise customized services for different stages and special parts of tunnel construction. During the supply guarantee period, the factory organized the heads of the quality control department and the sales department to go to the construction site to investigate the construction progress and understand the production process of large shield segments. The two sides exchanged views on key links such as tunnel supply guarantee technology, cement mix proportion and mixing amount. At the same time, according to the requirements of different parts of the tunnel construction, the compression and bending tests are carried out to ensure that the requirements of the tunnel construction are met. This deep communication and cooperation enables Conch Cement to accurately meet every detail of the project. Wuhu Shield Co., Ltd. of
China Railway 14th Bureau Group has highly recognized the quality and service of Conch Cement. Customers agree that the quality of Conch Cement is stable and the supply is timely to meet the production needs. This recognition is not only an affirmation of the quality of Conch Cement products, but also a praise of its service attitude and ability. Conch Cement has won the trust of customers and set a benchmark for cooperation in the industry with its business purpose of "high quality and sincere service".
