The starting point of the G329 Sunbu to Dawang Village first-class highway reconstruction project is located in Sunbu Town, Xuanzhou District, Xuancheng City, Anhui Province, across Xuanning Expressway, through Jitouling, Shuidong Town, Conch Cement Plant, and the end point is located in Dawang Village, with a total length of 20.18 kilometers, the construction will start on February 8, 2023, with a contract period of 30 months, and is expected to be completed and opened to traffic in the second half of 2025.
This section of the road is constructed according to the standard of two-way four-lane first-class highway, with a design speed of 80 km/h. After completion, it will effectively alleviate the traffic pressure between Xuanzhou District and Ningguo, further shorten the traffic time between Xuancheng City and cities along G329 National Highway, and make positive contributions to the integrated development of the Yangtze River Delta.
The asphalt professional subcontractor of this project is the construction company of Liju Group, a strategic major customer of Sanyi Road Crane, and the Sany equipment participating in the construction of the G329 project has two SSP80C-8 pavers, two STR130C-10C tandem rollers, one SPR300C-10H tire roller, and one SZR30C-8S roller. In the construction of the G329 Sunbu to Dawangcun section of the first-class highway reconstruction and expansion project, Sany pavement equipment has been praised by the owners and construction parties for its high convenience, efficient construction, durability and reliability.
The reconstruction and expansion of roads is different from the new construction, and the difficulty of project safety production management and emergency maintenance has increased significantly due to factors such as opening to traffic, construction and cross-operation, and the shuttle of vehicles and crowds at the project site have also brought certain pressure to construction safety.
Sany SPR300C-10H tire roller is equipped with a 360-degree panoramic cab, with no dead angle in the operation vision; adopts four-stage braking scheme, low action delay, large braking force and linearity, and industry-leading braking performance; can realize hydraulic wheel braking after the vehicle is powered off; equipped with active safety system, using millimeter wave radar collision avoidance + position sensor mechanical collision avoidance, and cooperating with Sany's self-developed active safety control algorithm, it can easily realize obstacle identification, collision prediction, intelligent deceleration and parking. Actively avoid obstacles to ensure safe construction with zero accidents.
On the working face of the asphalt surface course, the Sany STR130C-10C tandem roller is also busy shuttling. The 13-ton tandem roller, known as the "king of asphalt compaction", is equipped with a new generation of non-road China IV Cummins engine, which adopts the third-generation vibration energy-saving technology with invention patents, driving vibration peak reduction control, intelligent control engine and pump high-efficiency range matching, and lower use cost.
Equipped with flexible start-stop electronic control technology and dual-mode driving technology, the start-stop is more flexible. The stepless electronically controlled driving technology combined with the 67Hz high-frequency vibration technology allows the asphalt to be quickly formed at high temperatures, and the compacted pavement has higher flatness and compactness, helping the project to obtain high-quality construction pavement.
As one of the largest construction machinery in the industry, Sany stall and pressure equipment have been playing an important role in the protracted battle of rural road construction, and have worked with customers to build high-quality pavement projects with high-quality, high-standard and intelligent products, and made outstanding contributions to the high-quality development of rural roads!
