1In July, 990, Yan Zicai, who graduated from Southwest Jiaotong University with excellent results, not only obtained the admission qualification that his alma mater could study for a master's degree at any time within three years, but also stayed in the provincial bureau after being assigned to the fourth bureau. However, the formal work in the office has not heated up, and the notice of going to work and exercise at the grassroots level falls in the hand. Growing up in the countryside, he is no stranger to labor and is not afraid. He packed his bags and went to the north bridge site of Heying Bridge in Fuyang City, which was under construction by China Railway Fourth Bureau No.2 Company, and was assigned to Class Two, a comprehensive bridge section engaged in pure manual operation.
In the days of "labor training", Yan Zicai lived in a temporary adobe house with the workers on the construction site and poured concrete for the bridge deck together. Even once, because the rope was broken, he almost fell under a bridge more than 40 meters high. Fortunately, the worker grabbed his overalls, which was considered "near misses".
Gradually, Yan Zicai changed his original intention of "gilding" grass-roots construction sites. Lying on the edge of Datong shop, he wrote a letter directly to the director of the Fourth Bureau of China Railway, suggesting that the "labor training" on the production line should be extended from college graduates to all managers of the enterprise, and "transfer jobs" in batches on a regular basis, so as to facilitate the effective management and harmonious development of the enterprise. At the same time, he also showed his determination: "I will not return to the bureau after the expiration of labor training."
Break the routine and clear the "obstacles" for key projects in Shanghai
In August of 200 1 year, Yan Zicai was ordered to construct Yunzaobang Viaduct, a key municipal project in Shanghai.
This is a project called "obstacle" by Shanghai Key Project Command. The bridge is designed as a three-span prestressed concrete continuous beam. The construction technology is not difficult, but it is on the busy traffic artery of Gonghe New Road. In order to ensure the normal traffic of Gonghe New Road, a new bridge must be built next to the old one. After the new bridge is completed and opened to traffic, the old bridge will be demolished, and then a new bridge will be built on the old site. The engineering procedure is complicated and the site is particularly narrow, which can't affect the traffic. The original construction unit has nothing to do with the cracks in the old and new bridges, and the construction period has been delayed for half a year. This image project, which worries the leaders and concerns the people, is placed in an embarrassing situation where it is difficult to open to traffic on schedule. This project finally fell into the hands of the project management department led by Yan Zicai.
Many construction teams are timid before "getting in the way", because the pier foundation construction requires PHc600 pipe piles to be driven at low altitude, and the clearance is only 5 meters, which is undoubtedly like Yao Ming sleeping in a sleeper on the train, unable to open his legs. Yan Zicai boldly changed the construction scheme and changed the pipe pile into bored pile to improve the strength of concrete and meet the bearing capacity of bored L pile. At the same time, the drilling rig was reformed to make the original drilling rig smaller and shorter, and the operation process was completely adapted to the clearance height within 5 meters. The roar of the drilling rig finally lifted the eyebrows of the leaders of the engineering headquarters.
In order to speed up the progress and grab back the construction period, Yan Zicai made great efforts in innovation when it was still difficult to optimize the process organization and reverse the construction period in minutes, and put forward a conventional method of breaking the step-by-step construction of the cast-in-place section and the side span closure section of the bridge and implementing synchronous construction. This can be described as "the first person to eat crabs."
When the cast-in-place section of the bridge and the side span closure section are constructed simultaneously, the original internal prestress of the two sections will change. How many steel bars are laid in the bridge and how much strength does the concrete need? In order to ensure the balance of T-beam, how much back weight should be added during molding? Everything must be recalculated and tested. Yanzicai buried herself in front of the computer in front of her desk day and night. His eyes are red, and his back can hardly stand. After three days and nights, he finally finished all kinds of calculations and then finished the experiment.
A series of innovative reforms and scientific organization have advanced the whole construction period. Yan Zicai and his workmates have lived up to the trust and expectations of the people of Shanghai, and their reputation of "overcoming difficulties" is even louder.
Led the formulation of 10 management systems and promoted them within the group.
In June 2002, 35-year-old Yan Zicai was promoted to chief engineer of the second company. Runzi, who attended the leadership meeting for the first time after taking office, fired two shots at the meeting: establishing a management mechanism for engineering technical specifications and giving it to engineers and technicians for warmth. In his words: talent is the source of enterprise development, and engineering and technical personnel are like a swift horse, one needs to "get off" and the other needs to "feed". He wants to turn the technical staff of the whole company into a galloping horse for enterprise construction and production.
Therefore, he took the lead in refining technical management, and successively formulated many management systems, such as measurement review system, design document review system, technical disclosure system, etc. 10, which not only clarified the responsibilities of each technical post, but also clearly emphasized the strict supervision of the "responsible person", and conducted a quarterly work inspection to reward the excellent and punish the poor. At the same time, a series of incentive measures have been introduced: increasing the settling-in expenses of new college students; Implement the technical allowance system among engineering and technical personnel; Establish a special allowance system for post contributions; Establish the selection of "excellent technical supervisor and excellent chief engineer"; Establish a good employment mechanism for technical pacesetters, technical champions and technical experts; Welfare benefits are tilted towards technical talents.
The "cannon" quickly ignited the passion of engineers and technicians to "whip and leap" and formed an atmosphere of "respecting talents, knowledge and innovation" in enterprises. A large number of technicians work with peace of mind, take root in the front line, and the enterprise develops generate with new vitality. A leader of China Railway Fourth Bureau called this the crowning touch in technical management, and quickly promoted this "eye-catching" work in the group.
Every time you embroider a "rainbow", there is something "eye-catching".
Looking back at Yan Zicai's technological innovation achievements over the years, almost every time he embroiders a "rainbow", there is a touch of "envy".
65438-0995, Yan Zicai served as the technical director of the south bridge of Heying Bridge in Fuyang City. This is the first bridge where he really began to take technical responsibility. According to the characteristics of bridge engineering, he first designed the construction scheme of thin-walled concrete open caisson and rhombic hanging basket method, which successfully solved the problem of long cantilever splicing in T-truss construction.
During the period of 1998, Yan Zicai boldly adopted the I-type temporary horizontal prestress and lattice balance frame system in the construction of the V-shaped continuous rigid frame bridge in jiqingmen, Nanjing, and combined the V-shaped pier construction with the 0JHJ section construction support of the box girder, which not only solved the common problems of complicated internal forces such as root cracking and inaccurate alignment in the construction of the V-shaped pier, but also reduced the construction difficulty and saved the project cost.
200 1, Yan zicai adopted double-wall steel cofferdam technology in the construction of Huaihe railway bridge, which solved the problem that it is difficult to stand on the cofferdam construction on bare rock in deep water. The problem of underwater concrete leakage in deep water fine sand clay stratum is solved by using high pressure jet grouting pile to stop water. He presided over the whole floating and towing of multi-span steel beams at one time, creating a new record of the length of multi-support floating and towing steel beams in China of190.48m.. This first achievement in China won the "Second Prize of Anhui Science and Technology Progress".
From June 5438 to October 2004 10, 37-year-old Yan Zicai was appointed as the deputy chief engineer of China Railway Fourth Bureau, and later served as the director of the technical center of the bureau, focusing on comprehensive scientific research; In September, 2007, Yan Zicai became the chief engineer of China Railway Fourth Engineering Group with excellent technical innovation achievements and leadership ability. This created a bigger stage for his "eye-catching" works. The scientific research achievement of "Key Technology and Application of Digital Rail Transit Engineering Integration Construction" won the second prize of 2006 National Science and Technology Progress Award at the National Science and Technology Awards Conference held in the Central Committee of the Communist Party of China and the State Council on February 27th, 2006. The Technology Center of China Railway Fourth Bureau led by him was officially recognized as "National Enterprise Technology Center", and China Railway Fourth Bureau was rated as "National High-tech Enterprise".
As a technical leader, it laid a solid foundation for China to take off.
Yan Zicai, who took the post of technical management and left the construction line, still focused on the construction site and focused on the construction line, still making the finishing point and pioneering and innovating.
In 2004, the world-famous Hangzhou Bay Bridge started construction. This is an unprecedented feat of challenging nature in human history and has epoch-making significance in the history of bridge building in the world! Facing the eight technical problems encountered in offshore bridge construction, such as "shallow natural gas discharge, design, construction and safe operation of 9.78km super-long trestle, digital bridge construction, application of GPS in the whole construction process, development and construction of marine concrete, L-pile construction of super-long bored hole in offshore deep water area, and offshore pier foundation construction", Yan Zicai, as a bridge expert and main key researcher, often goes deep into the bridge site to study and determine the overall scheme. A lot of work has been done to track the implementation of supervision scheme and the control of key technologies on site. Finally, together with other technicians, the technical problems such as rapid positioning of bored L-piles, construction of long trestle, and preparation of marine durable concrete are solved. 34 sub-projects and 16 innovative achievements have been conquered successively, such as assembling cantilever guiding positioning frame for trestle construction, taking fresh water from offshore drilling, mixing ratio of marine concrete, assembling reinforced concrete bottom cofferdam, etc., which ensured the smooth completion of the bridge.
