"It was an unforgettable day, with the workers, staying up for several days and nights, and having a heated debate with colleagues on technical issues." Wang feels that he has accumulated a lot of practical experience in the construction site and improved his ability to coordinate and deal with daily problems.
Jiangyin Yangtze River Highway Bridge is the first super-large suspension bridge with a main span of over 65,438+0,000m in China. The project won the' Luban Award' of the national construction project, which is a sign that the Second Aviation Administration has made great strides in the field of road and bridge construction. At that time, I was the executive deputy manager in charge of the project. " Wang Zihao told reporters quietly.
Wang, 34, has been the director of the Second Aviation Administration since 2002. He is the youngest director in the history of the Second Aviation Administration and China Hong Kong Group. It took only 1 1.000 years for this Shanwazi from Sichuan to become the leader of a large state-owned enterprise with 1.65438 million employees. 199 1 After graduating from our school, Wang came to the Second Navigation Bureau and worked as a technician in the Shanghai Combined Sewage Treatment Plant. He worked with the workers' masters, sometimes staying up for three days and nights in a row, and everyone soon liked this thin and diligent young man.
Since 1990s, No.2 Aviation Administration has entered the road and bridge market from the field of port construction.
Jiangyin Yangtze River Bridge is the first world-class bridge project undertaken by the Bureau. The main span of this super-large suspension bridge is1.385m, ranking first in China and fourth in the world. 1995, 27-year-old Wang was appointed as the executive deputy manager of one of the bid sections, and he organized personnel to overcome major technical difficulties such as temperature control of mass concrete, formwork climbing construction and beam support. After the completion of Jiangyin Bridge, it won the "Eugene Figo" award issued by the International Bridge Association, and the brand of "Erhang" became popular. 1999, Wang, who has been assistant to the director of the Second Navigation Bureau, became the project manager of the Hubei-Huang Yangtze River Bridge.
Ehuang Bridge is located between Huanggang and Ezhou. The river is deep and steep, and there are faults, cracks and caves in underwater geology. Expert evaluation: All the difficulties in the construction of the Yangtze River Bridge are concentrated here.
To build a super-large bridge on the Yangtze River, it usually takes two dry seasons before the main pier appears. However, this time, the owner requested that the main wharf should not be flooded in the dry season.
Wang boldly adopted new technologies and processes-
Replace the traditional steel cofferdam platform with a high-piled drilling platform with a bottom steel hanging box; Unconventional use of "three-way positioning ship pile stability construction technology", nearly two football field-sized building steel platforms stand on the river in a week; The construction technology of "casing secondary drilling" was used to treat cracks and caves, and 19 rock-socketed bored piles with a diameter of 3m were completed in 99 days.
Wang led Avionics No.2 Company to overcome 19 technical difficulties and completed 19 scientific research projects, creating an amazing "Hubei-Huang speed":
In a dry season, the 1 main tower and four deep-water piers will emerge at the same time, which is the first time in the history of bridge construction in the Yangtze River. In seven and a half months, the 172-meter-high main cable tower was capped, setting a new record for tower construction; The bridge was closed one year ahead of schedule, creating the fastest construction speed of similar bridges.
The chief engineer of the Ministry of Communications praised: "It is a miracle that the geological environment is so bad, the excellent rate reaches 100%, and the elevation error of Helong section is only 2 mm!"
In 2002, when he was young, he took office and proposed to build a "century-old second airline" to cultivate core competitiveness and enhance the ability of sustainable development.
In just one year, No.2 Aviation Administration passed the certification of international integrated management system of quality, environment and occupational safety and health, and got the pass to participate in international competition. There are more than 10 branches in Chongqing, Wuhan, Wuhu and Zhenjiang, and more than 10 projects are distributed all over the country and abroad every year. Wang is located in Wuhan, mobilizing 100,000 troops and strategizing.
In the communication with Wang, you can find his inner stormy waves and great originality from his weak appearance and calm tone. He is not from a management background, but he is familiar with modern management and uses it well.
In the bidding for Hangzhou Bay Bridge, Wang staged a classic case of "cooperation and competition" in front of domestic and foreign experts:
Hangzhou Bay Bridge is the longest sea-crossing bridge under construction in the world, which is a contest between technology and equipment. Wang made a decisive decision: a joint venture with Japanese Chinese and Western companies, with an investment of 654.38+0.6 billion yuan, to build the most advanced crane ship in the world. This move enabled the Second Navigation Bureau to successfully win the bid for two tenders, with the contract amount exceeding 654.38 billion yuan.
More than that, Wang has more considerations: "The most direct thing is to diversify investment risks, and the most important thing is to strengthen cooperation with world-class peers. The deepest intention is to explore the path of restructuring the Second Aviation Administration."
Since the end of last year, the No.2 Aviation Administration has signed a new contract worth 7 billion yuan, and built five world-class bridges on the Yangtze River, ranking among the first corps of bridge construction in China.
