A drop of water sweeping the sea indecently, and see the world in a grain of sand.
From a steel cable on the “Chinese Sky Eye” to a grain of sand and gravel in the “highway plain” of Fengguanzhou; from a main cable on the sky high bridge to a “twist stick” in the moon exploration sky, the key to serious engineering failures is often determined by the breakthrough and distinction on the key components. Over the years, batches of restingers have overcome difficulties and continuously improved. They have used their craftsmanship to serve the national concept and help China invent their inventions. escort is also their unremitting efforts, allowing “a grain of sand” to build the road to the river and sea, and “a net” has brought up the world’s best, “a pin” to catch the dream of exploring the moon and flying in the sky…

“One grain of sand” builds the Tongjiangdahai Road
The high-profile majestic mountain gate. In 1935, the Red Army won great success here.
The heroic lord is like a turbulent iron, and now it is moving forward. Now, a new attack in northern Guizhou is ongoing.
The total length is 118 kilometers, and the bridge tunnel is 71.7% of the Chongqing-Zunyi section (Qianzhou) expansion project (simplified by Zunyi) of the Lanzhou-Haikou Guodu Expressway, which is a flat mountain.
According to the project to control the project, the total length is about 10.5 kilometers. He wants to go to the Sugar daddy listened to his daughter’s thoughts before making a decision, even if he and his wife had the same differences. The authenticity went into the last construction stage, and the pavement exhibition stopped synchronously with Sugar baby motor and greening.
This is the Tongzi tunnel of the Chongqing-Zunyi section (Qianzhou) expansion project of the Lanzhou-Haikou Guodu Expressway, which was taken on October 13, 2022. On that day, the right side of the Tongzi tunnel was then passed through. Xinhua News Agency reporter Tao Liang
To enable the longest tunnel of this precious-zhou expressway to be completed as soon as possible, the supply of data is guaranteed.
Leave the Qingqing Mixing Station, which is 23-tax road surface of the project, a truck that transports sand to make the machine is constantly entering, and the aggregate comes from a sand factory in Huanglien Township, Tongzi County around.
<p style="text-indent: In the factory shed, aggregates are stacked in seven specifications in detail. Zheng Zhiliang, director of the Z1 test room of the Z1 test room and the technical director of Zunyi Jiaoke Engineering Inspection Co., Ltd., said that aggregates only need to pass the sampling inspection before they can leave the venue.
“We have a baby mechanismSugar baby The raw materials of sand are mostly lime silt. “Qianzhou Expressway Group Co., Ltd. Director of the Mainland Development Project, said that Feizhou belongs to Karst, with more limes than the market, and the cost of building a large amount of materials nearby was greatly reduced when the site was taken to obtain materials nearby.

As a province in the country without plain support, Guizhou has high mountains and deep valleys, and does not have river sandSugar daddy capital, in the past, to support engineering support, we had to go to Chongqing, Hunan, Guangxi and even Malaysia to buy river sand, and the transportation cost was high.
To fight the data bottle, local builders and engineers have been able to develop 20 years of skill and research and development, and developed unique mechanical sand and childbirth techniques, grinding and modifying the rocks, and reaching Sugar daddy is comparable to river sandEscort manilaAfter the beautiful details and difficulties, EscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscortEscort daddy has become an inexhaustible raw material for building bridge development roads.
“We calculated that it is like buying in Guangxi. The river sand transportation cost per party is more than 350 yuan, while the cost of our homemade mechanical sand, which is the production, nearby transportation and other costs, each party only needs 50 yuan. ”Sugar daddyGeneral engineer of Guizhou Expressway Group Co., Ltd., said that this skill has been different and has accumulated billions or even hundreds of billions of yuan in capital for Guizhou Engineering Support.
“Mechanized sand utilization is a lifeline of our engineering support. “Zhi Liang said that the area of Sugar baby can build highways in a large area, and the utilization of mechanical sand has been achieved. In recent years, the Sugar baby tunnel and water-to-water bridge have been opened across the mountains. The Qianzhou Expressway has a vehicle mileage of more than 8,000 kilometers. The bridge beams have been built and under construction. baby30,000, the plateau with thousands of valleys has become a “high-speed plain”.
“A single cable” pulls up the most world’s best
After the “three-line support” era, Guizhou Steel Co., Ltd. has always been focusing on the research and development of steel wire ropes. Walking into the factory, the atmosphere of giving birth is coming from the hottest, and the various products ripped on the I-shaped wheel are waiting to be unloaded.
Leave and be wrapped by a mountaineering tigerEscort In the old office building of manila, there are also famous sayings such as “Manufacturing Single Championship Demonstration Enterprise” on the interior wall. Zhang Chengyu, deputy director of the skills center, said that the important aspects of their products are particularly rough, long, and special construction.
Taking the use of bridge beams as an example, the main cables and slings of the cable bridge, the cable-stayed cables of the cable-stayed bridge, as well as some construction cables, cat tracks and bearing cables used in the construction bridges, all have the figure of the Qianzhou Steel Scroll. The Huajiang Island Valley Bridge, which is being built and estimated to become the world’s tallest bridge after completion in 2025, is a cable bridge, and its slings use the sealed steel wire ropes they developed.
