At the critical stage of sprinting the annual target, the affiliated units of China Gezhouba Cement Company pressed the "fast-forward key" and pulled the "progress bar" to help the orderly progress of several key projects with high-quality products and all-round services, in accordance with the requirements of the labor competition target of "building a successful Gezhouba to ensure growth". The Qinjiahe Bridge of Shanghai-Chongqing-Chengdu High-speed Railway supplied by
"Three Gorges Brand" cement was completed
on November 22, and the down connecting line of Qinjiahe Bridge of Shanghai-Chongqing-Chengdu High-speed Railway supplied by Dangyang Company was successfully completed. It has drawn a successful conclusion for the box girder laying and erection of Shanghai-Chongqing-Chengdu high-speed railway in Longquan Town, Yiling District.
Qinjiahe Bridge is the first bridge on the west side of Yichang North Railway Station. It is an important passageway for high-speed railway to enter and exit Yichang North Railway Station. The bridge is 726.35 meters long. The bridge is divided into upstream, main and downstream connecting lines by turnout continuous beams. The main line extends westward to Chongqing, and the upstream and downstream connecting lines are connected with Zhengzhou-Wanzhou High-speed Railway. The first high-speed railway line with a speed of 350 kilometers per hour in Yichang has realized the interconnection between Yichang East Railway Station and Yichang North Railway Station.
In order to ensure the smooth completion of the bridge, the company closely contacts the project department of the 7th Bureau of China Railway, and will do its best to guarantee the supply of services throughout the concept, arrange special personnel to conduct in-depth docking exchanges with customers, rationally adjust the product structure according to customer needs, and effectively guarantee the construction safety, quality and progress with high-quality products and dedicated services. Up to now, more than 600000 tons of PO42.5 low-alkali iron standard cement have been supplied for the project, which has fully contributed to the "Three Gorges Brand" cement strength for the project construction.
Recently, the preliminary design of
the Libu Yangtze River Highway and Railway Bridge in Jingzhou has been approved by the Provincial Transportation Department and the Provincial Development and Reform Commission, which marks that the control project has taken a crucial step. It is about to enter the stage of full construction. In the early stage, all the cement needed for the test piles of the auxiliary piers of the main bridge of Bid 2 and Bid 3 of the project was supplied by Songzi Company, which has been successfully completed.
Libu Yangtze River Bridge is the world's first highway and railway dual-purpose bridge integrating the three functions of high-speed railway, expressway and municipal road. After completion, it will become the world's largest span highway and railway layered cable-stayed suspension system bridge and an important node of the southbound high-speed railway corridor in Hubei Province.
"Sanxia brand low-alkali cement produced by Songzi Company has the advantages of strong impermeability and durability, and all performance indicators can meet the national standards and our engineering technical requirements.". Enthusiastic service and timely delivery of sales personnel have played a positive role in promoting the smooth construction of the project. The project technicians of the Third Bureau of China Construction introduced the site construction. Baiguoshu No.1 Tunnel of Shanghai-Chongqing-Chengdu High-speed Railway supplied by
"Three Gorges Brand" cement was successfully completed
on November 19. Baiguoshu No.1 Tunnel, a key control project of Wuyi Section of Shanghai-Chongqing-Chengdu High-speed Railway supplied by Jingmen Company, was successfully completed, laying a solid foundation for subsequent girder erection and ballastless track construction.
Baiguoshu No.1 Tunnel is located in Jingmen City, Hubei Province, with a total length of 3023.3 meters. It is designed as a single-hole double-track tunnel with a speed of 350 kilometers per hour. It is the longest tunnel in Wuyi section of Shanghai-Chongqing-Chengdu high-speed railway. The tunnel is located in the soluble rock area, the geological conditions are complex, and it is easy to cause geological disasters such as mud burst and water gushing. It is the only first-class risk tunnel in the whole line, and the tunnel is located on the girder passage, the construction is difficult, the safety risk is high, and the quality requirements for cement products are particularly strict.
In order to meet the overall requirements of tunnel construction and ensure the construction period and quality, Jingmen Company dispatched special personnel to dock with the personnel of the project department, followed up and guided the whole process of cement supply, use and concrete allocation on site, actively cooperated with the project to adjust the construction plan, strictly controlled the quality of cement supply, and flexibly adjusted the product guarantee. Build a solid foundation for the smooth penetration of the tunnel.
It is reported that the Shanghai-Chongqing-Chengdu high-speed railway is one of the backbone corridors of the national "eight vertical and eight horizontal" high-speed railway, with a total length of about 2100 kilometers and a design speed of 350 kilometers per hour. After completion, it will connect the Yangtze River Delta urban agglomeration, the middle reaches of the Yangtze River urban agglomeration and the Chengdu-Chongqing two-city economic circle in series, which is of great significance to the construction of the comprehensive transportation system of the Yangtze River and the promotion of the development of the Yangtze River Economic Zone. The right side of Luochengling Tunnel of Xianning-Jiujiang Expressway supplied by
"Sanxia Brand" cement has been successfully completed
recently. The right side of Luochengling Tunnel of the first section of Xianning-Jiujiang Expressway supplied by Jiayu Company has been successfully completed. So far, 11 of the 12 tunnels of the whole line have been completed.
The tunnel is an important nodal closing work of Xian-Jiu Expressway Project, which not only effectively speeds up the construction progress, but also breaks through the "middle obstruction" of material transportation and construction machinery between the first and second bids, and opens up the transportation channel for the pavement construction of the whole line of Xian-Jiu Expressway Project. The construction of this project will directly connect Wuhan City Circle and Poyang Lake Ecological Economic Zone, which is of great significance to improve the layout of expressway network in Hubei Province, improve the traffic conditions in the old revolutionary areas of Hubei and Jiangxi, accelerate the development of tourism resources in Hubei and Jiangxi provinces and promote the economic and social development along the line.
In order to ensure the smooth construction of the second phase of the project, the company anchors the task objectives, requires special personnel to keep close contact with the project department of the construction party, keep abreast of the construction progress of the project, formulate production plans in time, provide technical support for the retarding cement required by the project, strictly control and guarantee the quality of the products, and lay a solid foundation for the opening of the project next year.
