In 2021, our company participated in the construction system science and technology project of zhongyifeng - "construction innovation technology of fair faced concrete high-rise bundle tube structure (268m Kangli elevator test tower)", which won the Huaxia Construction Science and technology award, reaching the international advanced level on the whole! The company is the first super-high beam tube structure fair faced concrete project undertaken by zhongyifeng, and also the first project in China to apply Zhuoliang formwork hydraulic climbing formwork to carry out fair faced concrete construction. The project is simple and flexible in shape, and has the highest height and fastest test speed in the world.

Huaxia Construction Science and technology award, as well as Luban Award and green building innovation award, is the highest award in the field of construction science and technology in China. The projects selected for the award need to reach the international advanced level, have greater technical difficulty and depth, play an important role in promoting the progress of Science and technology in the industry, and can achieve significant economic, social and environmental benefits. This is the first time that the company has won this award and the first major technological breakthrough.

Kangli elevator test tower has a building area of 17225m2, 2 floors underground, 33 floors above ground, and a building height of 268m. Based on the Kangli elevator test tower project and combined with the engineering difficulties, the research group has carried out systematic research and innovation on the major technical problems related to the high-rise beam tube structure of fair faced concrete, including "fair faced concrete construction method of high-rise beam tube structure based on hydraulic climbing formwork system", "C60 high-strength and high fluidity fair faced concrete mix proportion technology", and "high-strength and high fluidity fair faced concrete mix proportion technology" ”A series of technical research achievements, such as "the appearance quality optimization technology of 288M fair faced concrete outer surface". The scheme of fair faced concrete exterior wall can not only meet the requirement of maintenance free exterior wall, but also effectively reduce the construction cost, reduce the construction cost in many links, save the construction period and ensure the project quality. In this research topic, combined with the engineering difficulties, through the research of climbing formwork system, formwork support system, concrete mix proportion design and other construction technology improvement and innovation, formed a series of as cast finish concrete construction technology research.

In 2019, the science and technology project of construction system undertaken by zhongyifeng - "construction innovation technology of fair faced concrete high-rise bundle tube structure (268m Kangli elevator test tower)", passed the provincial scientific and technological achievements appraisal, and generally reached the international advanced level! It is also the first super-high beam tube structure fair faced concrete project undertaken by zhongyifeng. It is also the first project in China to apply Zhuoliang formwork hydraulic climbing formwork for fair faced concrete construction. The project is simple and flexible in shape, and has the highest height and fastest test speed in the world.
