on September 5, 2010, the raft foundation pouring project of Guangzhou East Tower, a landmark building in South China, was officially launched. In the next 50 hours, more than 80 Sany pumping equipment will continue to operate, and the pouring will be completed to carry the foundation raft of China's second tallest building in the future. The contractor, China Construction Fourth Engineering Bureau, chose Sany brand for all the pumping equipment poured in the East Tower, which is another classic construction project participated by SANY equipment after the future China's tallest building, Shanghai center, used Sany equipment to pour 60000 square meters of floor slab for 60 hours in a row in March this year

Sany equipment in the pouring construction of the bottom plate of the East Tower (the highest building in the figure is the "brother" of the East Tower - the West Tower)

the main tower of Guangzhou East Tower is 530 meters high, located in the central section of the CBD of Zhujiang New City, with a total land area of about 26000 square meters, integrating international finance, trade, commerce, culture and entertainment, administration, residence and other urban first-class functional facilities. After the completion of the East Tower, it will form twin towers with the capped West Tower opposite, which are located on both sides of the central axis of the new city, and the basement of the twin towers is connected by the underground space in the middle; Facing the Guangzhou TV Tower across the river in the south, and connecting Tianhe Sports Center and CITIC Building in the north, it will become the financial and business district in the center of Guangzhou, which will centrally reflect the image of Guangzhou as an international city

the total pouring volume of the large raft foundation of the East Tower is 30000 m3, which requires continuous pumping within 50 hours. The pumping mode is to pump down for 29 meters; The average thickness of concrete is 7.5m. Downward pumping is the most difficult construction in concrete pumping projects, and in order to ensure the strength of concrete, the concrete used in this project is C40 concrete, and the sand rate is only 37%, which is far lower than the sand rate of general pumped concrete, which puts forward more stringent requirements for the stability of pumping equipment due to the rising price of raw materials. Four Sany 48m pump trucks, six Sany on-board pumps, and 70 Sany mixer trucks will jointly accept this severe test

construction scenario of pouring the bottom plate of the East Tower

the contractor of Guangzhou East Tower - China Construction Fourth Engineering Bureau Co., Ltd. (hereinafter referred to as China Construction Fourth Bureau) is a large directly subordinate main company of the world's top 500 enterprise "China Construction Engineering Corporation" and a wholly-owned subsidiary of A-share listed enterprise China Construction Corporation Limited. In addition to the East Tower, only in Guangzhou, China Construction Fourth Engineering Bureau took the lead in the construction of Guangzhou West Tower, China's third tallest building, Jingji international finance building, Guangzhou Swire Plaza, Guangzhou Textile Expo City, the largest textile center in Asia in the future, Guangzhou Asian Games Village media village and other major projects. Mr. Ye Haowen, chairman of China Construction Fourth Engineering Bureau, said that the mature experience of China Construction Fourth Engineering Bureau in undertaking major projects over the years, using the heat energy released by plastic combustion to generate electricity, coupled with Sany's advanced technology and reliable equipment, the strong cooperation of the two enterprises is the guarantee for the successful completion of this pouring task

in addition to Sany's high-quality concrete equipment participating in the construction of the Shanghai center in the whole process, Sany Heavy Industry West Guangdong service company also specially formed a 20 person equipment support service team to enter the construction site before the start of the project, from the preparation before pouring to the whole process of tracking during pouring, providing "expert" services 24 hours a day

On August 28, all the experts and members of the equipment support service team sent from Sany headquarters were in place. In order to ensure the stability of the equipment in the construction project, the service team carried out free maintenance for the customer's construction equipment before construction. The reserves of common accessories and emergency accessories prepared by SANY headquarters were also delivered to the construction site in advance to ensure that they can be solved in time in case of equipment failure

the concrete equipment of the east tower floor pouring project adopts Sany brand

before the pouring work begins, Sany's service personnel form a set value ≥ 10% FS within ± 1.0% of the two small set values of equipment pre inspection and on-site pipe laying command. The equipment pre inspection team is responsible for a comprehensive overhaul and compulsory maintenance of all equipment involved in the project, eliminating potential safety hazards and eliminating most faults in the embryonic stage. The on-site pipe laying command group is served by engineers with rich construction experience sent by the headquarters, who are responsible for the on-site pipe laying command of customers and assist customers in pipe laying. During the 50 hour pouring process, there are also two pumping emergency teams and one mixer emergency team for on-site service. One group of two pumping emergency teams is responsible for the on-site repair of 6 on-board pumps, the other group is responsible for the on-site repair of 4 pump trucks, and the mixer truck emergency team is responsible for the on-site repair of 60 mixer trucks to ensure the smooth progress of construction

it is reported that the most important thing in this construction process is to ensure 50 hours of uninterrupted pouring, so the stability of the equipment is very important. In many domestic and foreign key projects, such as the Hong Kong International Financial Center, the Shanghai World Financial Center, the Guangzhou TV Tower, the Hong Kong World Trade Plaza, the Moscow federal building, the Dubai Tower Project in the United Arab Emirates, Sany's equipment can live up to its mission and successfully complete the task with high reliability, thus winning the trust of customers, This is also the reason why the floor of Shanghai center building was poured in March this year and the contractor of the East Tower Project chose Sany brand equipment. "Quality changes the world" is the business philosophy that Sany has always adhered to since its establishment. Participating in the construction of China's first and second tallest buildings is the specific practice of Sany's solemn commitment of "quality changes the world"
