Luoyang Jiujiu Technology Co., Ltd. Successfully Held the 2015 Baoduzhai Red Tourism Event
2015-09-17
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.
In August 2015, our company organized a two-day trip to Luanchuan Baoduzhai, themed "Remembering the Martyrs and Revisiting Our Revolutionary History."
The rugged, undulating terrain of Baodu Village stretches endlessly, its steep and perilous landscape serving as a natural fortress. Back then, PLA soldiers braved enemy fire—carrying explosive packs and scaling ladders—to liberate this ancient stronghold that had stood for millennia, rescuing the impoverished villagers from years of suffering. Here, employees visited the Heroes' Monument and watched a documentary chronicling the historic liberation of Baodu Village, vividly reenacting the courageous scenes of heroic martyrs who fearlessly fought valiantly to defend their homeland and safeguard their cherished home, no matter how daunting the challenges.
We followed in the footsteps of the revolutionary martyrs, revisiting this pivotal chapter of history. This experience deepened everyone’s appreciation for the hard-won happiness we enjoy today—and reinforced the enduring importance of remembering our past and honoring the sacrifices of those who came before us. At the same time, it fostered stronger communication among employees, strengthening the company’s sense of unity and enhancing our collaborative spirit, thus bringing this meaningful red-trip journey to a fitting close.

Drilling Well Flushing Technology
Abstract：This paper introduces the three core functions of well flushing in drilling: cooling drilling tools, removing cuttings and cleaning the bottom, and supporting the wellbore. It expounds the characteristics and selection requirements of four types of well flushing media. The two mainstream well flushing processes, direct circulation and reverse circulation, are compared, their respective characteristics are analyzed, and the technical parameter control standards for the reverse circulation process are clarified, which can provide a reference for field drilling construction.
Abstract: This paper introduces raise boring drilling, a highly efficient vertical shaft construction technique featuring reverse upward excavation from bottom to top. With advantages including high safety, low disturbance, and high efficiency, it is widely applied in mining, underground engineering, and other fields. The technology is divided into two categories: full-face raise boring and core barrel raise boring. Full-face raise boring, including pull-up and jack-up types, is suitable for large-diameter shafts and shafts of varying depths. Core barrel raise boring enables simultaneous shaft formation and geological coring, and is applicable to small‑to‑medium shallow‑to‑medium‑depth shafts. The technology is evolving toward intelligence, greater depth, and unmanned operation.
Abstract: This paper elaborates on bored pile drilling technology, identifying bored piles as an important type of cast-in-place end-bearing pile. Compared with precast piles, bored piles feature controllable costs, low steel consumption, strong capability for large-diameter and ultra-deep hole forming, wide geological applicability, and low environmental impact, while still facing deficiencies such as sediment cleaning and borehole wall mud cake issues. It also introduces the basic requirements, characteristics, conventional and innovative drilling processes, and points out the broad application prospects of this technology amid technological innovation.
