○ behind the curtain
In 3 years of many time, builder of nearly 10 thousand big bridges uses wisdom and science and technology, overcame wind, tide, stream, the harsh environment such as firedamp, created an another world most.
660 many pier, 36 thousand meters span, this not only refresh the mankind spans deep-sea record, and also will make the world on bridge history one new " Mount Everest " . Hangzhou bay crosses be well versed in of all fronts of Hai Daqiao yesterday, a in big bridge a record is medium, kept the figure of Anhui person everywhere.
Anhui army creates a company " new record "
"See big bridge be well versed in, very excited, very proud. " on June 26 afternoon, li Xuemin has feeling ground to say quite. The station crosses overlook of look as far as one can of Hai Daqiao south bank in Hangzhou bay, already of closure cross Hai Daqiao to be like megalosaurus to lie wave, grand and grand. But face this situation this scene, the builder that also has big bridge only just knows, they gave how many painstaking effort for this.
Li Xuemin, mound in relief person, bay of 4 bureaus Hangzhou crosses iron in the standing assistant manager of ministry of Hai Daqiao project, also be the chief engineer of project ministry, whole journey participated in the construction of big bridge. Yesterday afternoon, the Li Xuemin of spot of big bridge be well versed in, the telephone call that accepted a reporter is interviewed.
According to current public data, li Xuemin guided technical personnel to capture difficult problem of 7 cosmopolitan technologies: The sea is versed in the development of fast concrete is mixed apply, safety of shallow-layer natural gas is discharged beforehand, GPS whole journey is applied, the mound stage below condition of construction of landing stage of monitoring of whole process digitlization and management, maritime train in excess specified length and safe operation, ocean environment is construction, maritime construction of grown bore picket. Among them most those who let Li Xuemin remember profundity is " construction of landing stage of maritime train in excess specified length and safe operation " and " construction of picket of maritime and grown bore " . 9.78 kilometers landing stage, be south the channel with only construction of beach besmear area, can calls the world landing stage most, its safety is built and operation makes world-class task, li Xuemin is the group leader of this task group.
Start working is earlier 2003, because seabed distributings,methane natural gas, offing often has 8 class above and even the factor such as 12 class gale, landing stage construction for a time slower. For this, li Xuemin calls together technical personnel to study plan for many times, to the total construction of landing stage design and the programme of construction have sufficient proof, make span of landing stage design increases 15 meters 12 meters by every picket. The landing stage after building resisted successfully " Mai Sha " , " card exert " wait for strong typhoon 17 times invade.
A few days ago, in bay of 4 bureaus Hangzhou crosses ironwork Cheng ministry of Hai Daqiao project is in house of Beijing Diaoyutai state guest to obtain special honour: The construction craft that Hangzhou bay crosses landing stage of train in excess specified length of sea big bridge and shallow-layer natural gas to discharge is brought into enterprise of the 10th batch of China " new record " .
