According to a report by Tianjin TV's "Tianjin News", on May 26th, the construction project for the expansion and seepage prevention reinforcement of the Erwangzhuang Reservoir, an important hub project of Tianjin's Luan River Diversion and Yangtze River Diversion projects, was officially launched.

Jing'an Heavy Industry has multiple TRD (Trenchless Diaphragm Wall Drilling Rig) equipment distributed on the reinforced embankment of the Erwangzhuang Reservoir. The TRD cutter head is inserted into the ground for 40 to 50 meters, and the chain cutter on the cutter head stirs the cement-soil slurry. As the TRD equipment continues to advance forward, a solid underground diaphragm wall is built, serving as an underground barrier for seepage prevention and reinforcement of the embankment.

In 2024, the TRD7095 chain cutter wall-forming machine developed by Xuzhou Jing'an Heavy Industry Machinery Manufacturing Co., Ltd. was selected as the first major equipment of Jiangsu Province for the year. Seizing the opportunity presented by the national increase in investment in water conservancy projects, the company has been continuously improving the TRD equipment series and enhancing its production capacity with a sense of urgency. Through the "quick, simple, and effective" tactics, Jing'an's TRD equipment quickly entered the market and achieved a good market share. In the first quarter of this year, during the dam reinforcement construction of Dongting Lake, Jing'an Heavy Industry stood out and fully demonstrated the market competitiveness of Jing'an's TRD equipment.

Guided by market demand, Jing'an Heavy Industry focuses on the research, development, and manufacturing of specialized pile driving equipment. It has established a "rapid research and rapid production" market response mechanism, achieved fruitful results, and become one of the national-level "little giant" enterprises specializing in precision, specialty, uniqueness, and novelty.
