Civilization "Flower" is opened for the second time

——The project in the Jining area of ​​China Railway Twenty -five Bureau has been written on the side of the provincial safety and civilized standardization site.

The winds in July came to the rain in time, and the dried ground rejuvenated. Just like the weather in the early days of the rain, Zhang Zhihua, the head of the Jining District project of China Railway Twenty -five Bureau, was so comfortable that he and the two projects under the jurisdiction of the team were evaluated in Shandong Province's safe and civilized standardization site.

"Jining Expressway Engineering Project and Jining Taibai Lake New Area Aozi Road Cross Lao Canal Bridge Project both were awarded the honorary titles of the Safety and Civilization Standard Site of Shandong Province in Shandong Province."

"When the flowers are often encountered alone, the flowers bloom and you are strange." A good news reported that the work exchange group in the company caused a good praise.

Safety is our day

"Presidents, safety is the sky of our engineering person. Without safety, the sky collapses." This is the mantra that Zhang Zhihua, the head of the project department Zhang Zhihua, often hangs on his mouth.

Under his advocacy, the project was strong in safety.

"Giveting workers, workers' helmet must be worn! Absolutely not to play! Let the workers take some medicines for heatstroke and cool down." Wang Yingfang, who is responsible for safety, said.

The strictness of safety is the most true love. In the project department, the "safety knowledge" over and over, stringing daily management.

At the construction site of the old Canal Road in Jining Olympic Sports Road, the river soil was soft and adjacent to the main roads and river channels, which brought a lot of challenges to construction safety.

To this end, the project department has established a safety management team with the project leader as the team leader, and combined with the actual construction, scientifically and reasonably compile a safety management plan. The person in charge, security officers, protectors, and technicians on the site implementation system followed by the side of the class to monitor the construction process; establish a closed -loop management system for inspection, analysis, and rectification.

Nevertheless, the security protector did not dare to take it lightly. "As long as there is risks in construction, you have to watch the sixth road, listen to the eight parties, and strictly control the safety of the on -site operation." Wear a whistle and hold records in hand, becoming a standard equipment for each safety protector.

Up to now, 90%of the total cost of the total contract cost of the Old Canal Bridge project of the Olympic Sports Road of the Taibai Lake New Area in Jining. A 460 -day no safety accident, no environmental accident, and fire liability accident.

The quality is not allowed "almost"

"You can't think that it is almost okay. There is no different, and quality standards must be met." The chief engineer of the project told the construction staff while walking.

Under the relevant requirements of the company's continuous promotion of the "project standardized management year" and "standardization management deepening year", the "fault" of engineering quality, technical control, and process and process is the consistent style of on -site managers. The quality of engineering is good or not, to a large extent on construction technology and building materials.

In terms of construction technology, the project carries out template innovation, and the new template is used for the construction of the beams and columns. Strictly control the technical parameters of concrete raw materials, strictly monitor the pouring and vibration process of concrete, and ensure that the concrete is dense. Each work revolves from beginning to end to improve the quality of the project, and pays attention to details to ensure the quality of each detail of the project, thereby improving the overall quality of the project.

"At the beginning, the project strictly control the quality of the use of materials. Under the principle of quality priority, select preferred brand materials, and choose honest and credible qualified suppliers." Zhang Zhihua, the person in charge of the project, introduced. After the material enters the field, the principle of first testing and then use is strictly implemented to prevent unqualified materials mixed into the construction site. In terms of the amount of building materials, the ingredients and feeding are also strictly based on design and specifications to ensure that the quality and amount of engineering materials meet the requirements of design and specifications.

In addition, during the construction process, the project department used meetings, training, publicity and other methods to continuously strengthen the safety and civilized construction awareness of management personnel and construction personnel. During the construction, the site was sprinkled in time to reduce the dust, and the coverage of the naked soil in the operation area reached 100%. Set up spray systems at the construction office of earthwork excavation, infrastructure, and foundation pit excavation on site. Sprinkle water is not less than 6 times a day. The sprinkler spray time is not less than 6 hours. Dead ends.

On June 20, 2022, the construction unit organized the completion and acceptance meeting of the first phase of the Jining Expressway Project. At the acceptance meeting, all participants agreed that the construction technical indicators of the first phase of the Jining Expressway project were The requirements of technical specifications, standards and construction diagrams, reasonable engineering design, qualified engineering quality, complete engineering archives, compliance with the standards of acceptance and acceptance, and successfully passed the acceptance.

"The project is given to you, the people of Jining are assured"

In the early winter of November 2020, the cold wind did not block the big dry upsurge. A lively observation meeting was held at the construction site of Dongwai Ring Road in Jining. More than 60 people from the government, owner units, supervision units, construction enterprises, and reporters were interesting to observe its "air dance" on the spot.

Everyone took pictures and recorded short videos. At 2:15 in the morning, with the traction of the two jacks, after 45 minutes of counterclockwise rotating, the rotary bridge weighing 18,000 tons successfully crossed the new ruling railway.

Steady Railway on Jining Expressway cross -railway

The newly -spanned newly intersects with the three major north and south trunk lines of Beijing -Guangzhou, Beijing -Kowloon, and Beijing and Shanghai. On average, there is a train every 15 minutes. Data show that this rotary bridge is equivalent to the weight of 12,000 cars, and it also needs to cross the newly rotor to the newly risks, and the construction risk is large. Zhang Zhihua, the manager of the Jining Expressway Project of China Railway 25th Bureau: In order to achieve the smooth turning of the bridge, we rationally prepare the construction plan, apply steel bars to tie the fetal frame, use a qualitative steel mold, pour the formation on the prefabricated table, and on the box beams in the box beam. The automatic spraying system is installed in the prefabricated area, which is automatically and regular to maintain the prefabricated box beam to ensure the quality of the box beam.

"In addition, in order to ensure a safe and precise rotation, select the" Sky Window Point "of the railway operation from 1:30 to 2:30 in the morning for the transfer of the rotary construction, and use the Beidou satellite navigation system to measure the bridge body. To ensure the accurate docking of the turntable beam and the bridge pier. The practicality of the Beidou system, the signal strength and measurement accuracy are improved compared to GPS. "Liu Chengqi, chief of the project, said.

"You are good, the project is given to you, and the people of Jining are assured." The representative of the owner praised after watching. The Jining Municipal Government, Jining Highway Bureau, etc. have come to thank you many times, praising this as "a team that is particularly hard -working and fighting."

"We always adhere to the continuous deepening of the management level of the area with standardized management, continue to strengthen regional operations, and achieve rolling development in the highway and municipal fields. Great contribution. "Zhang Zhihua said.

At present, they are trying to march to the honor of the "Taishan Cup" ...

"A unique show is not spring, and the flowers are full of spring garden." We firmly believe that under the fine cultivation, there will be more "iron construction flowers" blooming on the land of Jining!
