According to a report by Tianjin TV's "Tianjin News," on May 26, the anti-seepage reinforcement construction project of the Erwangzhuang Reservoir expansion project—an important hub of Tianjin's Luan River Diversion Project and Yangtze River Diversion Project—commenced.

Multiple TRD (chain cutter trench cutter for underground diaphragm walls) units from Jing'an Heavy Industry are deployed onthe Erwangzhuang Reservoirraised cofferdam. The TRD cutter box is inserted forty to fifty meters underground, and the chain cutters on the cutter box churn the cement-soil slurry. As the TRD equipment continuously advances, a solid underground diaphragm wall is built, forming an underground barrier for anti-seepage reinforcement of the dam.

In 2024, the TDR7095 chain cutter trench cutter developed by Xuzhou Jing'an Heavy Industry Machinery Manufacturing Co., Ltd. was selected as one of Jiangsu Province's first (set) major equipment for 2024. Seizing the opportunity of the country's increased investment in water conservancy project construction, the company, with a spirit of seizing every moment, has continuously improved its TRD equipment series and enhanced TRD equipment production capacity. Through a "quick and efficient" strategy, Jing'an TRD equipment quickly entered the market and achieved a good market share. In the first quarter of this year, during dam reinforcement construction at Dongting Lake, Jing'an Heavy Industry stood out even more, fully demonstrating the market competitiveness of Jing'an TRD equipment.

Guided by market demand, Jing'an Heavy Industry focuses on the R&D and manufacturing of specializedpile-drivingequipment, has established a "rapid R&D and rapid production" market response mechanism, achieved fruitful results, and joined the ranks ofnational-level specialized, refined, distinctive and innovative"little giant"enterprises.
