At 9:30 am on August 3, the last steel beam in the center of Shanghai was hoisted in place to cap the main structure of 580 meters and the tallest building in China was born. It is understood that during the construction of Shanghai Center, up to now, a total of 23 units of SANY pumping equipment to participate in operations, pouring floor 60,000 square, pouring the main structure over 90,000 square. Among them, "China Pump King" once again create a single vertical pumping pump new height, reaching 580 meters.
580 meters Chinese pump king to create a new vertical pump pump a new height
"I've been doing this line for more than 20 years, and I used to use foreign brands before, but the appearance of SANY changed the situation. Shanghai Construction started using the Sany pump from 2003 and Sany pump as we did a lot Large projects, Shanghai is now 70-80% of the landmark projects are completed, like 492 meters next to Shanghai World Financial Center, Trinity products really good, service is good.
Xue Zhengming is a construction supervisor of Shanghai Construction Engineering and participated in the construction of Shanghai Center. At the construction site, he pointed to the Shanghai World Financial Center near the Shanghai Center and said: "I have been involved in the construction of most of the tall buildings in Shanghai. Before, all the pumps we used were overseas, and their products were not bad at that time. However, we found that the materials Roughly speaking, they will not do anything and will not be able to beat them, and in comparison, I still think that SANY's pump is good. "
When it comes to the March 1 pump, Xue Zhengming told reporters a story. At that time, the person in charge of construction in Shanghai on the 31st trailer in the end how high heart did not end. "We are ready to pick up a tractor at 400 meters in the building and then call up." The head of this idea will be disclosed to the Trinity, Trinity Institute of breast cancer assurance, Trinity trailers will be able to "pump in the end" , Do not need to pick a midway pump.
Out of the trust of Trinity, Shanghai Construction Engineering selected the then Trinity developed ace products - HBT90CH2150D EHV concrete pump. The outlet pressure of the extra-high pressure pump is up to 50MPa and the total power is (273 × 2) kW, which guarantees double the outlet pressure and the power of the whole machine during the pumping construction of the super high-rise building. The theoretical pumping height is more than 800 meters.
"More than 1700 days down, Sanyotong pump stable quality, pumping ability, which makes us worry." As a faithful fans Sanyi products, Xue Zhengming HBT90CH2150D EHV concrete pump amazed. "Especially in high-temperature environment, the job, Trinity drag pump no burst pipe, plugging phenomenon."
In addition, the cap of the main structure of Shanghai Center also means that "China Pump King" single pump vertical pumping capacity of 580 meters, creating a new height.
15 Wanfang 23 sets of equipment pouring Shanghai Center
Shanghai Center, to be completed in 2014, is located in Shanghai Lujiazui Financial Center and covers an area of ​​over 30,000 square meters. It is an integrated building integrating office, hotel and sightseeing. Upon completion, Jinmao Tower and Shanghai World Financial Center will form a "product" shaped super high-rise buildings.
The main structure of the Shanghai center capped, built on a thickness of two floors, an area equivalent to 1.6 standard football ground on the floor. This floor concrete pouring volume equivalent to one-quarter pumping a quarter of the global financial center, is the world floor volume of civilian buildings most.
By the end of March 2010, 18 Trinity equipment was under construction. After more than 60 hours of day and night fighting, 12 pump trucks, 4 tow pumps and 2 car pumps successfully completed the 60,000 square concrete pouring task.
"Uninterrupted pumping of more than 60,000 square feet of ultra-high-strength concrete in more than 60 hours is a tremendous test for pumping equipment, both in terms of construction and pumping difficulty." In industry experts Come, "Uninterrupted pumping of 60,000 square ultra-high-strength concrete in one go, previously unimaginable, is rare in the world."
In April of that year, after the pouring of the floor was completed, 31 sets of tow pumps and 2 sets of fabric bars began to carry high-rise concrete. As of August 6, this year, it completed the concrete pouring operation of the 123-core core barrel and the 110-story peripheral wall in Shanghai Tower, and poured more than 90,000 square meters of concrete.
It is understood that the pumping strength of the concrete grade C60, but after the addition of concrete admixtures, the concrete strength of the actual pumping level reached C100. "If pumping plain concrete to pumping tap water, pumping ultra-high strength concrete such as C100 is pumping asphalt," industry experts told reporters, high-strength concrete pumping equipment requirements are very high.
Such a large national key projects, such a difficult project, the contractor Shanghai Construction Engineering, but all of the 23 pumping equipment all selected Sany brand. Shanghai Construction Engineering official said: "If not for many years on the quality of Trinity full trust, we are certainly not dare to do so."
Seventy of China's 70% super tall buildings are pumped by Trinity equipment
According to statistics, so far, the whole country has been completed and under construction in Shanghai, Guangdong , Hong Kong, Taiwan, Liaoning and other places, 31 pump equipment involved in the construction of nine of them, accounting for the country's ultra-high-rise buildings near 70%. More than 500 meters of skyscrapers in China, then all are responsible for the construction of SANY equipment. SANY therefore laid the absolute leading position in the domestic and global high-rise pumping field.
Looking ahead, the Shanghai World Financial Center adjacent to the construction site of Shanghai Central is still eye-catching. The 491-meter tall today, the tallest building in China, also uses a Trinity device during construction and created a world record for single-pumped vertical concrete at the time. Sany Heavy Industry Chief Engineer Yi Xiaogang has proudly said: "how high architectural design, equipment can be pumped by Trinity." Today, the Sany pump once again created China's first new high.
Hu Jianhua, deputy general manager of Shanghai Construction First Construction Co., Ltd., said: "In actual terms, like Trinity's commitment, Trinity's equipment is the best in service, cost performance and process maturity in China, The best, we hope to work together with Trinity to continue the project of Shanghai Center. "
Hu Jianhua told reporters that in addition to the full participation of concrete equipment in the construction of Shanghai Center, Trinity also set up a special service team stationed in the special field, providing "expert-level" service around the clock. Day and night in the Sany equipment continuous construction at the same time, the service staff also keep fighting at the site, did not miss the slightest device anomalies, to ensure that the construction foolproof.
According to "squatting" site super service engineer Lin Zi introduced, as of now, 31 equipment in addition to the normal replacement of wearing parts, there is no other major fault. "The entire construction project may be completed before the end of this year, after the main structure of the ceiling, Trinity equipment will also be responsible for concrete pumping peripheral wall tasks."Electric Power Converter
