en.Wedoany.com Reported - On August 5, with the completion of the pouring of the last cast-in-place pile in the water tank area, the pile foundation construction of the water tank area of the Tongchuan Compressed Air Energy Storage Project undertaken by CEEC Construction Group was successfully concluded.
Strictly Upholding Bottom Lines to Build Defenses, Weaving a Dense Safety Management Network
The project department firmly established the safety concept that "without safety as the '1', all other elements are '0'", placing safe production at the top priority. In response to the construction characteristics of complex geological conditions and intensive cross operations, the project department strictly implemented safety control requirements such as the "Eight Uniforms" and "Ten Hard Measures", deepened the mechanism of "no construction without video surveillance", promoted the application scenarios of "AI + Safety", and empowered safety management with technological means.
In view of the characteristics of numerous large mechanical equipment and frequent cross operations in the pile foundation construction of the water tank area, the project department implemented lean safety down to the working face and built a safety control system covering "all personnel, the entire process, and full coverage". Before construction, the project department solidly carried out the dual prevention mechanism of risk classification and control and hidden danger investigation and treatment, conducted identity verification for every piece of equipment entering the site, and provided safety technical disclosure and physical examination screening for every worker, strictly prohibiting "working with illness". During construction, full-time safety officers were stationed on the front line throughout the process, implementing "day and night" two-shift safety inspections, with key monitoring on high-risk links such as the movement of rotary drilling rigs, hoisting of reinforcement cages, and concrete pouring, and establishing a closed-loop management mechanism of "hidden danger detection - immediate rectification - re-inspection and closure". At the same time, the construction site strictly implemented civilized construction and environmental protection requirements, with mist cannons and sprinkler systems installed to effectively suppress dust pollution, adhering to the concept of green construction, and achieving the established goal of "zero accidents" in safe production.
Meticulous Control with Strict Management, Crafting High Quality with Ingenuity
Facing extreme geological conditions such as dramatic undulations in the underground rock surface, with a maximum elevation difference of nearly 20 meters in the rock layer beneath the same water tank, and the highly uneven distribution of backfilled moderately weathered schist, the project department adhered to scientific construction, letting data speak, and strictly controlling quality.
The project department adopted a forward-looking plan of "exploratory drilling for each pile with dynamic feedback", organizing rotary drilling rigs to excavate exploratory holes at the original pile positions, with technical personnel taking shifts to stay on site and record rock layer changes in real time. A total of dozens of exploratory holes were arranged, with real-time data synchronously transmitted to the geological survey and design teams. After multi-party verification, the rock entry depth of each pile was scientifically determined, and construction parameters were reasonably optimized on the premise of meeting bearing capacity requirements. In terms of raw material control, the "double inspection" system for incoming materials was strictly implemented, with all main materials such as steel reinforcement and concrete fully traceable and archived. Each process, including hole formation, hole cleaning, fabrication and installation of reinforcement cages, and concrete pouring, implemented the "self-inspection, mutual inspection, and special inspection" three-inspection system, and process parameters such as mud density and drilling speed were adjusted in real time based on geological changes, achieving refined management and dynamic optimization. Quality acceptance at all stages, including pile foundation testing, passed at one go, with all technical indicators fully meeting design standards.
Lean Party Building to Promote Development, Demonstrating Responsibility on the Front Line
Facing the multiple pressures of tight schedule, high standards, and complex geology, the party branch of the project department fully leveraged the leading role of party building, implemented "lean party building" management, and promptly established a "Water Tank Area Pile Foundation Construction" party member commando team and a youth safety production demonstration post. All party members took the lead in rooting themselves on the front line and charging ahead, planting the party flag at the forefront of tackling tough tasks.
In response to the highly uneven distribution of backfilled moderately weathered schist, the "uneven" rotary drilling construction, and the frequent replacement of drill bits that seriously affected progress, the party member commando team took the lead in stationing on site, recording changes in drilling parameters in real time, jointly analyzing drill bit wear patterns with manufacturer technical personnel, and scientifically adjusting the drill tooth configuration plan, effectively improving drilling efficiency. At the same time, a mechanism of "daily reporting and weekly review" was established, with daily statistics on the number of completed piles, average footage, and abnormal conditions, and weekly summaries and analyses of typical problems to form improvement lists, achieving deep integration and synchronized resonance between party building and production. The party branch also ensured care and support for frontline personnel, setting up "cooling stations" and party member service teams at the construction site, equipped with heatstroke prevention medicines, mung bean soup, etc., and reasonably arranging rest rotation schedules. The role of the party organization as a fighting fortress and the exemplary vanguard role of party members were fully demonstrated throughout the pile foundation construction process, injecting "red momentum" into the smooth achievement of various milestone goals.
Mentoring Pairing for Knowledge Transfer, Accelerating Youth Development
Youth account for 80% of the project team. The project department regarded the tough battle of water tank area pile foundation construction as a "training ground" for cultivating young talent. The party branch delineated "party member responsibility zones" and implemented a mentoring pairing model of "one party member leading multiple young employees", placing responsibilities, providing platforms, and promoting growth through practical combat.
The project department also focused on identifying and training young employees in urgent, difficult, dangerous, and heavy tasks, arranging young technicians to independently take charge of technical management and data compilation for specific areas, and encouraging them to identify problems, propose solutions, and drive resolutions on the front line. From the operating principles of rotary drilling rigs to hole-forming processes under complex geological conditions, from fabrication specifications for reinforcement cages to key technical points of concrete pouring, young employees grew rapidly through practical combat. At the same time, a business exchange platform was built to foster an atmosphere of learning and competition. The project department regularly organized youth symposiums, where project leaders communicated face-to-face with young employees, listened to the difficulties and problems encountered in technical research, and promptly helped resolve practical difficulties in work and life, allowing young employees to work with ease. Multiple "technicians explain drawings" activities were carried out, arranging young technicians to take the podium and, based on their responsible construction areas, explain technical details such as pile layout, reinforcement requirements, and concrete grades against the design drawings, with the project chief engineer and other technical backbone providing on-site comments, supplements, and corrections. Promoting learning through teaching and training through lecturing forced young employees to proactively study drawings, thoroughly understand specifications, exercise their presentation skills, and consolidate their professional foundation, reserving solid talent strength for the continued high-quality advancement of the project.
In the next step, the project department will continue to firmly adhere to milestone goals, advance subsequent project construction in a whole-process, high-standard, and lean manner, strive to build the project into a benchmark project for the company's strategic emerging industries, and deliver a satisfactory answer sheet with solid work and tangible results.
