In the continuous tea mountains in the southwest of Zhejiang Province, the 150000 mu tea garden in Songyang is rising with the spring breeze. This land, where tea has been planted since the Three Kingdoms Period, is the largest green tea producing market in China. Every year, more than 80,000 tons of tea are sold from here to the whole country. The aroma of famous tea such as "Songyang Silver Monkey" and "Suichang Longgu" drifts along the mountain road to thousands of households in the Yangtze River Delta. In the depths of the tea garden, a steel artery is extending forward through the mountains, and cement tankers with the "CONCH" logo shuttle back and forth, pouring high-quality cement produced by Jiande Conch into piers, tunnels and roadbeds, paving a fast passage to the outside world for this thousand-year-old tea village. As a key project connecting Quzhou and Lishui, the Quzhou-Lishui Railway Project
under
construction is a key project of the national medium and long-term railway network planning, with a total length of 160.1 kilometers and a design speed of 200 kilometers per hour. In March 2026, the bridge and tunnel of the whole line have been completed, and the second phase of Quzhou-Songyang section is 95.1 kilometers long, which is currently in the stage of construction. After the opening of the whole line, it will end the history of no high-speed rail in Suichang and Songyang counties. The journey from Songyang to Hangzhou will be shortened from three hours to one hour. Spring tea, which originally took two days to be transported to Beijing, will be delivered to consumers on the same day in the future.
Jiande Conch, as the main cement supplier of several key sections of Qu-Li Railway, has successfully guaranteed the construction needs of several control engineering nodes with high-quality products and services, and has built a solid material base for the construction of the Tea Township Gongfu Railway. The total cement supply is expected to reach 1.42 million tons.
Back in November 2025, one morning, as soon as Xiao Chen, the sales manager of Jiande Conch, arrived at the office, he received a call from Wang, the manager of the project material department: Xiao Chen, the main body of Chengpingxi Bridge will be poured next week, and 1800 tons of P.O4 2.5 low-alkali cement will be needed. The plan is large and the time is urgent. Can it be delivered on time?
"Rest assured that the construction period will not be delayed!" Xiao Chen hung up the phone and immediately coordinated all departments to start the supply guarantee plan: the production department produced P.O42.5 low-alkali cement at full capacity two days ahead of schedule, the quality department followed the whole process to ensure that the indicators met the railway engineering standards, coordinated the fleet to increase 8 cement tankers in advance, planned special transport routes to avoid peak traffic sections, and each vehicle was equipped with GPS real-time monitoring. The driver is familiar with the route in advance. At 5 A. M. on the third day, the first tanker arrived at the construction site smoothly, three hours ahead of schedule.
The customer looked at the tankers coming in one after another and said with a smile, "We all thought that the supply guarantee was not so timely, but we didn't expect you to arrange it so thoughtfully. The service of conch is really unspeakable!"
Later, Xiao Chen recalled the busy experience in Songyang, where the tea fragrance lingered, and felt a little more in his heart-the bridge and tunnel ratio
of Quli Railway was close to 89%, and the tunnel had to cross dozens of geological faults. Bridges have to cross mountain valleys, which require high strength, corrosion resistance and stability of cement. Only with high strength in the early stage, can it adapt to the rhythm of rapid construction in mountainous areas; only with strong resistance to sulfate erosion, can it cope with the complex geological environment of groundwater; only with good stability in the later stage, can it guarantee the service life of the project for a hundred years. As Songyang tea farmers often say, "Three years of land cultivation produces good tea", a piece of tea has to go through many processes of deactivation of enzymes, rolling and drying to have a long fragrance and mellow taste, while cement, the cornerstone of infrastructure projects supporting the development of economy, transportation and people's livelihood, has been calcined at thousands of degrees of high temperature, fine grinding and multi-round testing. This kind of stubbornness of "well-tempered material" is the conch's adherence to "the highest quality, sincere service".
In this way, truckloads of conch cement set out from Jiande Conch Factory and drove to the mountains in southwestern Zhejiang. The cement supplied by Jiande Conch has penetrated into every key part of Qu-Li Railway from the successful closure of the 128-meter tied arch of Chengpingxi Bridge to the breakthrough of the 5000-meter mark in the excavation of Yejiadian Tunnel, and then to the preparatory stage of track laying in the 3rd bid of Songli Section of Phase I. Up to now, all batches of cement supplied have zero quality objections and zero supply delays, which have been praised by owners and construction parties for many times.
Nowadays, the project progress of Qu-Li Railway has become a "top priority" in Xiao Chen's mind, and he often thinks that in the near future, when the high-speed rail carrying tourists and tea merchants fly between the tea mountains and bamboo seas in southwestern Zhejiang, the spring tea picked in the morning will appear in the teahouses of Shanghai and Hangzhou on the same day. When Suichang's long dumplings and Songyang's Torreya grandis are sold to the whole country through this railway, the tiny powder born in the mountains, after condensing the wisdom and sweat of the conch people, has now returned to the mountains where it belongs, completing the transformation from industrial products to the link of common prosperity, and will also become another vivid footnote for the conch to help the rural revitalization in the mountainous areas of southwestern Zhejiang.
