The embankment is narrowest at 6 meters, widest at 8 meters

Height 10 meters, slope 21 degrees

Conducting TRD method construction on such a narrow embankment?

Isn't this directly discouraging?

Today

Let's change our perspective

To see Shanggong Machinery's first pure electric TRD-C40E method machine

Shouldering its mission, setting out for the first time

To assist in the construction of China's second-largest freshwater lake's massive remediation project

The Dongting Lake area key embankment reinforcement project

Steadily advancing for dam body filling!

The first phase of the Dongting Lake area key embankment reinforcement project in Hunan Province is one of the 150 major water conservancy projects in the country. The Dongting Lake area has a total of 226 embankments of various sizes, of which 11 are nationally recognized key embankments. Since the flood control efforts in 1998, due to poor embankment soil quality and poor foundation geological conditions for a long time, coupled with frequent exceedance of the design flood level in recent years, the flood control safety of key embankments cannot be guaranteed, and embankment reinforcement construction is needed.

According to the importance of the protected objects, among the 11 key embankments, 6 key embankments—Songli, Anzao, Yuanli, Changchun, Lannihu, and Huarong Hucheng—were selected for comprehensive standard-compliant reinforcement treatment. The project duration is 45 months, with a total investment of 8.5 billion yuan.

The section participating in this project is the first-line flood control embankment of Songzaowan. On this winding embankment with a total length of 88.7 km, embankment reinforcement construction is carried out. Due to the extremely narrow dam body, terrain elevation differences, and fragile ecological environment, the construction is extremely difficult, placing higher demands on construction equipment.

After the first pure electric TRD-C40E method machine of Shanggong Machinery rolled off the production line, it set out for the first time and went straight to the first-line flood control embankment of Songzaowan in the Dongting Lake area to construct a multi-section water-stop curtain continuous wall with a depth of 32 m and a wall thickness of 550 mm on the narrow embankment. At the site, the TRD-C40E method machine, with its excellent practical performance, became a beautiful scenery on the embankment.

First Deployment, Battling a Major Water Conservancy Project

The embankment is narrowest at 6 meters, widest at 8 meters, height 10 meters, slope 21 degrees. Just this narrow construction site makes it difficult for many similar TRD method machines to operate. The TRD-C40E method machine, with its small body size, low power consumption, and a newly designed pure electric driven crawler chassis, has stronger mobility and higher construction efficiency.

The TRD-C40E method machine has a dual power system: a pure electric main power system and a hydraulic auxiliary system (pure electric drive, higher efficiency, energy saving and environmental protection). It can adjust motor speed and motor torque to meet different geological requirements. The equipment has a maximum construction depth of 50 m, wall width of 550-900 mm, and net construction height of 6.8 m-10 m. At the same time, the equipment has an intelligent construction management system, making operation and management easier, allowing owners to track the construction process and remotely supervise construction quality.

On-site operator Master Wang exclaimed: The TRD-40E pure electric power is completely comparable to diesel engine power, yet far more energy-saving and environmentally friendly than diesel engine power. It only uses 3 kWh per cubic meter. The on-site geological layers are mainly silty clay, silty sand, and cobbles. The equipment's cutting speed can reach 2-3 m/h, with nearly 20 hours of work per day. The equipment runs continuously with a very low failure rate. With two shifts of personnel, work efficiency is very high. Shanggong is a brand I have always trusted, and this product's performance has indeed not disappointed us!

Thoughtful Service   Full Support

Due to limited site space, terrain elevation differences, and the need to protect the fragile ecological environment, the TRD-C40E method machine also faces numerous difficult challenges. Although advance preparations were made on site before construction, unexpected situations are unavoidable.

To this end, Shanggong Machinery dispatched a professional service team to station at the project site for a long time, on call 24 hours a day, ready to respond to service needs at any time, ensuring safe, efficient, and stable support for project construction.

▲Service team supporting project construction

After the implementation of the Dongting Lake area key embankment reinforcement project, the flood control capacity of each key embankment will be effectively improved, greatly reducing the pressure of flood control, conducive to promoting high-quality social and economic development, conducive to social stability and unity, and its benefits will permeate all aspects of social economy and people's lives.

▲TRD-C40E method machine working on site

As the market demand for water-stop curtain continuous wall construction increases year by year, TRD method machines and equipment construction methods have been widely used in water conservancy project construction, foundation pit support, subway stations, sealing and isolation of pollution sources, revetment, and other purposes. With the gradual increase of domestic application cases of TRD construction technology, the superiority of TRD construction will be gradually verified. We firmly believe that TRD construction technology will usher in a magnificent blooming in the near future.
