Recently, 23 Jintai hydraulic diaphragm wall grabs have arrived one after another at the construction site of Shanghai Baoshan High-Speed Railway Station, forming a rare full-model equipment cluster operation scenario in China's underground engineering field. With the outstanding technical performance parameters of Jintai grabs, the construction site presents the full product line of the Jintai SG series in a concentrated manner, precisely adapting to the construction conditions of the 63m ultra-deep diaphragm wall at Shanghai Baoshan High-Speed Railway Station and providing an efficient solution for the construction of a Yangtze River Delta transportation hub.

     Shanghai Baoshan Station of the high-speed railway is the originating station of the Shanghai-Chongqing-Chengdu High-Speed Railway (the northern route along the Yangtze River) and also the northern starting point of Shanghai's newly built Rail Transit Line 19, while connecting multiple important railway and highway networks that are already built, under construction, or planned. Once completed, it will completely rewrite the transportation landscape of northern Shanghai, becoming not only a key node connecting the Yangtze River Delta, the Yangtze River Economic Belt, and the coastal economic belt, but also a super hub that receives the radiation of the center to the south, links across the river to the north, connects to the Pudong Leading Zone to the east, and links to the Yangtze River Economic Belt to the west. The project strata: 1-30m silt layer; 30-50m soil layer; 50-63m gravel layer.

     The diaphragm wall project of Baoshan High-Speed Railway Station faces multiple construction challenges: First, recent severe weather in Shanghai such as sustained high temperatures, typhoons, and heavy rainfall, with surface temperatures exceeding 70°C, poses a great test to the physical fitness of engineering personnel and equipment stability; second, the project requires the construction of an ultra-deep diaphragm wall with a trench width of 1.2m and a trench depth of 63m, breaking through conventional operating depths; third, the schedule is tight, with the operation time for each panel strictly controlled at 15-16 hours, placing extremely high demands on equipment performance and construction organization.

     To cope with the multiple challenges brought by severe climate and ultra-deep diaphragm wall construction, Jintai has deployed a dedicated service team integrating "equipment + technology + service" for 24-hour service, ensuring stable operation of the equipment under high-temperature environments. The project manager stated: "The Jintai team takes equipment as the foundation and uses service to build a solid guarantee line for construction. This all-weather response model makes construction under complex working conditions controllable."

     Shanghai Jintai Engineering Machinery Co., Ltd. has been deeply engaged in the field of underground engineering equipment for nearly 70 years, and the market share of its SG series hydraulic grabs has ranked first in the industry for more than 10 consecutive years. Adhering to the century-engineering philosophy of "co-creation and co-building," the company continues to promote the modernization of China's foundation construction equipment.
