Hail, rain and snow all the year round, and the severe lack of oxygen in the no-man's land in northern Tibet add a lot of horror to the Tanggula Mountains at an altitude of more than 5,000 meters. The young college students of China Railway 18th Bureau Group 1 Company, who undertook the construction task of the ninth tender section of the Qinghai-Tibet Railway, played a series of high-pitched road-building movements when they collided with the dangerous living environment with their youth and wisdom.
Ensure quality without hidden danger
The 12.8-kilometer construction mileage of China Railway 18th Bureau Group 1 Company is either located on the permafrost layer or in the swamp wetland. The sub-projects have high technological content, which virtually increases the difficulty of construction and puts forward special requirements for project quality control. .
In order to ensure the quality of railway construction in special sections and eliminate the hidden dangers of accidents from the root, Liu Guisheng, the head of the safety and quality department, who shoulders the responsibility of safety and quality, started from the opening of the construction title page, in accordance with the quality control system. The "three inspections" system of inspection and reporting to the resident project supervisor for strict inspection is taken seriously as a solid foundation for building a solid project quality dam and creating a first-class engineering brand. It requires engineering and technical personnel responsible for the entire process of implementation at the construction site Starting from the standardization of on-site process form filling and reporting, a more rigorous work style has been developed, the overall sense of responsibility has been strengthened, and the quality of physical engineering construction and the quality of internal data sorting and archiving have been improved.
While doing a good job of macro control in the construction pipe section under his jurisdiction, Liu Guisheng used his professional vision acquired in safety and quality work for a long time to eliminate "impurities" in the construction of extremely complicated sub-projects to ensure the integrity of each process under special geological structure conditions. High level.
In the Yiqiaodailu No. 1 super-large bridge, when the pile foundation of one of the piers is being poured with concrete, the steel casing that blocks the quicksand collapse and the steel hook that protrudes from the pier cap to break the pile and connect the pile are out of proportion. A small negligence, although it will not affect the load-bearing capacity of the bridge pier, will bring some troubles to the follow-up project. Liu Guisheng seized the problem and called back the construction team that had already evacuated from the site. According to the technical requirements, he standardized the ratio of the steel casing and the steel bar, and cleared the obstacles for the construction from the details with a meticulous spirit.
Show your skills in times of crisis
As a director of the engineering technology department of the company, Zheng Yan regards going deep into the front line of construction, understanding practical problems, and sinking down to help the grassroots solve construction technical problems as her work goals, and constantly drives responsibility and passion, the "wind" "fire wheel" to make fruitful work performance.
On August 3 last year, during the construction of the nearly two-kilometer Riana Zangbute Bridge in Amdo County, Tibet, the No. 2 bored pile of No. 35 pier was completed. When more than one meter of frozen layer and quicksand layer were pulled out, Zheng Yan, who was guiding the construction on site, intuitively felt signs of precipitation around the bored piles. After cleaning up the sediment in the hole according to the process procedures, when reporting to the resident supervisor for inspection, reserve an additional 30 cm of drilling diameter, which has been reduced to 20 cm. If no drastic measures are taken, the permanently thawed parts will be partially thawed under the action of mechanical drilling friction and heat. The frozen layer, as well as the quicksand layer with little support and stability, may soon silt up the pile foundation pits of the piers formed by drilling.
At a critical juncture where there was no room for any hesitation, Zheng Yan, in addition to taking emergency measures such as commanding the mechanical equipment for on-site construction, quickly hoisting and placing the steel casing for solid walls, and delaying the shrinkage of the borehole diameter, quickly notified the headquarters through the walkie-talkie to dispatch the reinforcement cage. When they arrived at the site, they activated the mixing plant with insulation measures at the same time, mixed the concrete urgently, and started a battle for time against the dreaded formation extrusion and sedimentation.
After the reinforcement cage and the mixed concrete arrived at the site, Zheng Yan was in a state of extreme physical and energy exhaustion because he kept walking back and forth in the high cold and hypoxic environment and gave various operating instructions, but he did not evacuate the site. With a super passion and will to deal with emergencies, until the bored pile foundation pit was poured with reinforced concrete, and then dragged his tired body back to the headquarters.
Self-aware financial responsibility
Since the Qinghai-Tibet Railway is a large-scale project, the storage and transportation of various project consumables and materials, as well as labor costs, supplies and guarantees for the participating teams, etc., must be converted in the form of financial currency. If there is any negligence in financial management, it will be It is possible to make the whole construction fall into a passive predicament. Zhou Weidong, Chief Financial Officer of the Qinghai-Tibet Line Headquarters of China Railway 18th Bureau Group 1 Company, organically integrated the advanced and agile thinking and responsibility consciousness of college students in the new era into financial management, and exchanged knowledge and sweat for a good construction environment.
When a construction team of more than 1,000 people entered the site, Zhou Weidong realized that the timely payment of wages to migrant workers participating in the construction was an important part of management. After implementing the detailed financial management rules, devote energy to go to the site to find out the specific strength and number of migrant workers participating in the construction, and plug the management loopholes. On this basis, Xiao Zhou, relying on a more sensitive professional sense, adopted a mandatory measure on the spot where migrant workers received wages and had to sign and return them to the finance department for filing. Using strict rules and regulations, they first stopped some leaders of migrant workers. The evil thoughts of keeping the money privately after getting it, or simply leaving it, eliminated the phenomenon that migrant workers could not get the money for their efforts and had disputes with the construction unit.
Taking the initiative to resolve conflicts, for the sake of construction, but also for the benefit of migrant workers, is another focus of Zhou Weidong in the process of financial management and operation.
A migrant worker team from Golmud, Qinghai Province, more than 700 kilometers away, came to the construction site. Due to lack of skills and experience, they asked for travel expenses to go home after working on the construction site for a period of time. Xiao Zhou calculated the amount of work done by the migrant workers, and after deducting the uniform distribution of clothing and living supplies uniformly distributed by the unit, he found that the migrant workers still owed the unit several thousand yuan. In the situation where the two sides were at a stalemate, Xiao Zhou, through meticulous work, persuaded the head of the migrant worker team to write off the money owed by the migrant workers in the form of attendance and work days under the condition that the unit guarantees their living conditions, which will soon intensify. The contradictions of the conflicts are eliminated in the bud.
