up to date!The Hangzhou -Ningbo Reproduction Ningbo Phase I project Binhai Viaduct Establishment is completed

Today (0818) In the morning, the construction site of the Binhai Viaduct Bridge of the Ningbo Phase I project of Zhejiang Provincial Transportation Group Hangzhou -Ningbo Reunion Line was under the command of the Sixteen Bureau of Railway 16. , Another pores of prefabricated box beams accurately "landing" marked the complete completion of the Hangzhou -Ningbo Reprinting Line Ningbo Phase I project. The box beam standing of the bridge provides convenient conditions, and it also lays a solid foundation for the main line of the project waters.

The first phase of the Ningbo Phase of the Hangzhou -Ningbo Reunion Line is invested and constructed by Zhejiang Transportation Group. Among them, the Binhai Viaduct mainly connects the Xupu Interchange and Binhai Interchange of the project. The bridge is 4.5 kilometers long. There are 156 pillow beams of the rice, 16 fillets of 40 meters, 16 pieces of pre -production box beams, 720 pile foundations, 178 inheritance, and 178 vase pier body. Binhai viaduct and box beams in the sea section

The beams, transport beams, and frame beams are all constructed by the China Railway 16th Bureau Group. Among them, the 50 -meter -wide pre -production box beam weighs 1,800 tons. It is currently the heaviest rectification prefabricated box beam of the domestic highway construction system beam.

1800 tons of "Big Mac" contains "black technology"

"The" big guy "weighing 1800 tons that everyone saw in front of them is not the" simple zoom "of ordinary box beams. In order to ensure a prefabrication of the box beams, we joined the Ningbo Institute of Engineering and buried 124 in the beam body 124 Monitoring devices such as temperature sensors and 174 stress sensors are equivalent to implanting nearly 300 "nerve endings" in this "giant" beam sheet to perform real -time monitoring and monitoring of the box beams. The whole process tracking testing and analysis research provides comprehensive real -time data and professional technical guarantee for the pouring and later maintenance, storage, transportation, and setting up. "Wang Xiaofei, the person in charge of the first phase of Ningbo project in the Hangzhou -Ningbo Foundation of China Railway 16th Bureau.

The project vigorously promotes the innovation of craftsmanship and method. Through technological means such as the "BIM" model and 3D animation technology, the technical difficulties in the prefabricated, transportation, and erection of the box beams are repeatedly simulated. The overall of the 100 -ton tire handling machine is lifted into the mold to ensure the overall tied and molding of the box beam steel. At the same time, the tincture of the plug -in vibration tinkel and the attachment vibrator vibration is supplemented, and the construction of 640 square meters of concrete was completed within 6 hours, setting a new record for domestic large tonnage box beam prefabricated, realizing the realization, realization The breakthrough of "from 0 to 1" and "from scratch" has also filled the gap in the relevant domestic construction field.

460 acres of box beam prefabrication center realize "intelligent" management

How to manage the prefabricated center of the box beams with an area of ​​460 acres, how to store the box beams after the production of the box beams ... and so on, after the production of large tonnage box beams, another series of engineering management is difficult. In the early days of the project construction, in order to use the foundation of the beach, two pore box beams weighing 1,800 tons of "double storage beams" weighing 1,800 tons were achieved. The beach coating is transformed into a high -standard modern beam.

The steel processing workshop of the project box beam prefabricated center covers an area of ​​more than 6,500 square meters. All of them are intelligent CNC mechanical equipment. As long as 18 workers cooperate, they can achieve fully automatic and uninterrupted assembly steel steel processing operations. The project relies on platforms such as the "Liangchang Butler" and "Sunshine Project". At the same time, combined with assistive measures such as smart access control and video surveillance, the personnel attendance is transparent, the construction progress is dynamic, and the engineering management system is systematized. , Safety Education Training Experience Park and other facilities, carefully create a "smart beam farm".

The bridge machine of 512 wheels realizes "beams on the beam"

The Hangzhou -Ningbo Foundation Line Ningbo Phase I project is located in the sea area, surrounded by densely pipelines in Ningbo Zhenhai Chemical Zone. During the construction process, it is necessary to cross 17 underwater pipelines of national economy and people's livelihood in 17, such as the water pipeline of natural gas pipelines (LNG), imported crude oil pipelines, Zhenhai Power Plant's water shield tunnel, Zhoushan water supply pipeline, Zhoushan 500 kV sea cable, and drainage pipeline. The construction organization is complicated. At the same time, because the construction area is mainly coated with the beach and shallow seas, the water level is shallow, and the ship can be used to set up a ship. It is also necessary to face technical problems such as the super high bridge deck and the high and low pier, 1800 -meter super small curve radius. The way to transport the beam to the beam to achieve the most pre -made box beams in China. The successful realization of the mission of the beam is inseparable from the perfect cooperation of the two "big powers", the two "big powers". It is understood that the YL1800 transport beam car adopted by China Railway 16th Bureau Group adopts a modular design with a total of 512 tires. The vehicle weighs 760 tons, the rated carrier capacity is 1800 tons. 5.6 meters, equivalent to the size of four badminton courts. At the same time, the JQ1800 "Yuehai" bridge machine adopted by the project is the first independent research and development of my country and the world's largest highway bridge machine.

The first phase of Ningbo project in Hangzhou -Ning Dynasty is the first large -scale PPP highway project in the field of transportation infrastructure in Zhejiang Province, and it is also an important iconic project to sing the "double city" of Hangzhou -Ning Dynasty.

"Since the beginning of this year, the project has thoroughly implemented the spirit of the 15th Provincial Party Congress, strictly strictly followed Zhejiang Transportation Group's" bravery to be a strong force, and strive to build the activity of the leading soldiers' activities to sound the assembly number promoted at the high speed of the project. With the concern and support of superior units such as the Bureau, Ningbo Maritime Safety Administration, Ningbo Gao Construction Center, etc., with the joint efforts of nearly 4,000 construction personnel in 90 teams across the line, it has steadily improved quality, courageous to attack, and the project construction has entered the 'Express. The Tao is a good pioneer for the "two advances" for our province. "Yang Chengan, deputy general manager of the first phase of Ningbo project of Zhejiang Transportation Group, Hangzhou -Ningnhachi Line, said. As of August 10, the project had completed a total of 14.507 billion yuan, accounting for 80.63%of the total budget investment, and the overall image progress was 85.1%. It is expected to be completed by the end of 2023.
