"World Pump King" to create ultra-high-level pump "Trinity"
October 31, 2022
Recently, Shanghai Lujiazui Financial Center, the main height of 580 meters Shanghai Center successfully capped. The "China Pump King," said the reputation of the Trinity EHV trailers again to break the record, to create a single pump vertical pumping new heights.
Shanghai Center is the first high-rise over 600 meters in China with a core of 123 floors up to 580 meters. The core of the cap, for the industry has set a super high-level pumping of the classic model project, creating a super high-pumping "Trinity."
Liang Linhe, chairman of Sany Pumping Division, said: "580 meters is not only a high degree of breakthrough, but also a perfect leap from the Chinese pump king to the world pump king in March."
Trinity has a full set of mature construction experience for super high-rise buildings
August 3, China's tallest building in Shanghai center structure of the main cap, pumping height of 580 meters, once again refresh the previous record has been maintained in the country's highest pump. After the completion of the Shanghai Center's exterior tubular column, the Shanghai Center will reach a design height of 632 meters, and it is quite likely that SANY will create a new single-pump vertical pumping world record of 632 meters.
According to incomplete statistics, since 2002, SANY EHV concrete pump has been built in Hong Kong International Finance Center, China 117 Building, Suzhou International Financial Center, Guangzhou East Tower, Shanghai World Financial Center and other high buildings. 80% of high-rise buildings under construction are under construction by Trinity; all tall buildings above 500 meters are all involved in the construction of Sany's pumping equipment. Putzmeister in 2006 created the world's highest pumping record of 606 meters in Burj Dubai, the tallest building in the world. Now Putzmeister has become one with Trinity.
When it comes to Sany's EHV trailing pumps, Wang Anlin, an industry expert, said that he observed the construction of Shanghai World Financial Center in 2007 with 31 ultra-high pressure trailers. "At that time, SANYT dragged the pump 492 meters and created a world record of single-pump vertical pumping."
Why the Trinity has repeatedly set a world record in the field of high-rise pumping and has always maintained its global leadership position? Industry experts believe that this is mainly due to the high-rise buildings, Trinity already has a complete set of mature construction experience .
"This set of construction experience has five highlights, including stable and reliable equipment, long wearing consumables, unique piping technology, pipelines developed independently and super high-level washing technology." SANY Pumped Research Institute Yang workers told reporters.
According to reports, the reliability of equipment, Trinity Ultra-high pressure towing two diesel engines were used to drive two sets of pumps. The application of dual power and power confluence technology, usually two sets of pump work at the same time, when a group of fault can cut off the group, the other group still maintain 50% of the displacement to continue to work to avoid interruption of the construction process. Can work simultaneously to improve work efficiency, but also separate operations.
"Needless to say, the water-washing technology ( pump technology ) is the leading technology in China and around the world." Yang said that the super-high-rise concrete direct washing process ensures that the concrete in the pipeline is pressurized to the construction site with high-pressure water. How high the pump, washed high. "For Hong Kong's international financial center, this technology saves customers about HK $ 1.9 million and protects the environment."
In fact, Trinity's pipe routing process is also very unique. According to Yang workers introduced last year in a Wuhan site, a brand of a 26 MPa tow pump in pumping 200 meters tall, has been unable to pump up. Later, the construction side had to resort to the construction equipment on March 1. "Our product was 22 megapascals, and pumping was very easy at the time."
Mention this case, Yang workers believe that, in addition to the equipment there is a gap, the two sides of the pipe technology maturity is also different. "Sany owned more than a decade of mature technology, the domestic high-rise buildings over 500 meters are all Trinity equipment responsible for the construction, which can not find a second country."
Echelon management of a clear division of labor for the customer to make money
With the cap of the main structure of Shanghai Tower, the tallest building in China, "Global Big Brother" of "China Pump King" is full of demeanor.
Struggling in the concrete industry for more than 20 years Xue Zhengming, director of Shanghai Construction Equipment, not only highly recognized the Trinity equipment, but also greatly appreciated Trinity's management mode. "This is one of the reasons for Shanghai Construction Engineering to maintain 10-year cooperation with Trinity."
It is understood that in order to do this project, SANY quickly set up the project department. The project department continues the echelon management model, which includes three modules: the research and development support module headed by Wang Youyi, the president of SANY Pumped Research Institute, and the service support module led by Liu Ai- rong, general manager of Pumping Division Service Company. The on-site work consists of Lin Xi is responsible. "
These three modules interlocking. According to Lin Xi introduced each month they will hold a scene coordination meeting, equipment problems, research institutes, service companies, on-site responsible for the three modules speak their mind to jointly solve the problem of equipment.
The reliability of the equipment, the Institute responsible for the overall negative. Every month, Trinity will dispatch relevant technical experts to Shanghai center to check the operation status of the equipment and ensure that the technical parameters of the equipment are correct.
"For example, in the case of a 500-meter high-rise building, if it is shut down, the wasted concrete in a single pipe will reach 10 square meters, and the concrete cost per square meter will be about 600 yuan, which does not include other losses caused by downtime. Of the pump, every stoppage, probably give customers a loss of one hundred thousand yuan. "Sany Institute Liu workers told reporters. Liu workers in the field of hydraulic has more than 10 years of experience, each super high-rise pumping project, the company will send him to participate, tracking equipment throughout the hydraulic conditions.
Similarly, in on-site coordination, Lin Xi said pumping agents in Shanghai have also given full support. "For example, every time we need to replace consumable parts, Shanghai agents will be sent quickly to deliver them." In terms of service, SANY has been greatly appreciated by customers.
Service "double insurance" on-site stay with the "fast" experts reserve army
In addition to the high-quality concrete equipment involved in the construction of the Shanghai Center, Sany also set up a first-class special services team stationed in the site, 24 hours a day to provide "expert" service. In addition, many experienced "fast reversal" experts also joined in.
During the pouring of the floor of Shanghai Center, the service team of Trinity-20 multi-person service stationed at the construction site more than 10 hours before construction, with 24-hour shift, did not miss the slightest equipment anomalies to ensure the construction quality. Continuous construction equipment, service personnel are also fighting continuously.
In the previous work, taking into account the particularity of this project, SANY specially dispatched R & D engineers to carry out large-scale training on customer operators and equipment supervisors. The training contents include: equipment safety operation rules, knowledge of safe operation of long boom truck and generous The amount of various types of transport considerations, all possible problems to be addressed in the early stage to ensure that the construction process foolproof.
In the meantime, SANY Pumped the Department of Quality Assurance and Research Institute to conduct a series of comprehensive testing and inspection on all the cylinder arms, pin shafts, jibs and connecting rods involved in the construction so as to conduct investigation on all possible hidden dangers. It is these nuanced, comprehensive and thoughtful preparatory work before allowing SANY equipment in high-intensity work environment without any accidents.
Xie Xiangyang, an expert on the "31" with the title of "doctor of medicine," also participated in the construction of the Shanghai center. According to Xie Xiangyang introduction, the entire project construction, Sanyi products did not appear too big a fault. Some time ago tank cylinder commutation system failure, but also in the joint service of super service engineers and Xie Xiangyang successfully resolved, Shanghai Construction Engineering is also very satisfied with this.
