The domestic infrastructure sector kicked off 2026 with robust prosperity. Fueled by the dual support of policies and funding, major underground projects have been intensively launched, driving a surge in demand for shield tunneling equipment. This has in turn unleashed definite growth potential for upstream consumable sectors such as wear-resistant materials and seals. With the expansion of application scenarios and breakthroughs in overseas exports, the industrial chain synergy effect has become increasingly prominent, ushering the industry into an era of value revaluation and high-quality development opportunities.

The "Zhenxing" tunnel boring machine used for the right line of the Yanlu Passage over-river project is a 15-meter-class, ultra-large-diameter slurry shield designed and manufactured by CCCC Tianhe specifically for Nanjing's cross-river tunnel. The tunnel’s shield-driven section spans a total length of 2,975 meters. This project features significant characteristics such as a large cross-section, high water pressure, extended distances, and exceptionally abrasive ground conditions. Moreover, most of the construction lies beneath the riverbed, with the hardest rock layers in the hard-rock sections exceeding 70 MPa in strength. The diverse and complex geological conditions place extremely stringent demands on the cutting tools used during excavation.

Luoyang Jiujiu Technology Co., Ltd. 20th Anniversary Celebration & Yuntai Mountain Resort Retreat
In August 2016, to celebrate the company’s 20th anniversary, a Yuntai Mountain resort getaway was held under the theme "Moving Forward Together, Creating Brilliant Futures." Yuntai Mountain, historically known as "Fufu Mountain," earned its second name due to its towering peaks and the perpetual clouds and mist that shroud the mountain throughout the year. The terrain is rugged and steep, with pristine forests blanketing the entire area. Towering over the landscape are deep, serene valleys dotted with crystal-clear streams and tranquil pools, complemented by countless breathtaking waterfalls and cascading springs. The scenery is nothing short of picturesque, featuring uniquely shaped rock formations that seem straight out of a dream.

Luoyang Jiujiu Technology Co., Ltd. Successfully Held the 2015 Baoduzhai Red Tourism Event
In August 2015, our company organized a two-day trip to Luanchuan Baoduzhai, themed "Remembering the Martyrs and Revisiting Our Red History." Baoduzhai boasts rugged, undulating terrain that stretches endlessly, with its steep and perilous landscape. Back then, PLA soldiers bravely carried explosive packs and scaling ladders, defying enemy fire to liberate this ancient fortress—once home to generations of impoverished villagers trapped in dire suffering. At the site, employees paid tribute at the Heroes' Monument, watched a documentary chronicling the liberation of Baoduzhai, and witnessed firsthand the inspiring scenes of heroic martyrs fearlessly battling through relentless challenges to safeguard their homeland and protect their cherished community.
