Consulting unit for the project.

Owner approach of sustainability

The project focuses on the general goal of protecting industrial style, inheriting culture and stimulating new momentum, and actively promotes the transformation and development of old industrial zones. In the process, aiming at three aspects of planning and design, intelligent application and reconstruction construction, continuous practice on the road of green intelligent transformation and construction has achieved the desired goal satisfactorily.

Firstly, it realizes the reconstruction and functional regeneration of industrial heritage space at the planning and design level, excavates and deliberates the industrial heritage form, and carries out the block reservation and spatial reconstruction without destroying the overall industrial atmosphere, so as to ensure the perfect continuation of the industrial beauty of "plain face". Secondly, high-standard certification of green evaluation of industrial parks has been achieved at the level of energy-saving renovation, and Research on organic combination and effective utilization of old industrial buildings and green renewable energy has been carried out. Thirdly, BIM model data integration and digital management platform are realized at the application level of building intelligence. Fourthly, at the level of reconstruction and construction, the key technologies of protective demolition, old reinforcement and transformation are optimized and upgraded, and finally the new path of transformation and development of old industrial zones in urban areas is constructed.

At present, more than 120 old industrial cities in China are promoting transformation and upgrading. Many old industrial enterprises in cities have visited Shougang Old Industrial Zone for investigation. The practical experience of transformation and development of Shougang Old Industrial Zone provides useful reference for the transformation and development of old industrial zones in urban areas of China.

Architectural description

1. Application of Waste Building Materials

In the landscape project of XiShi Winter Olympic Plaza, some abandoned building materials and equipment facilities are used for artistic reprocessing and become landscape sketch facilities. After silo window opening, the remaining complete concrete blocks are transformed into outdoor tables and benches and landscape devices. Waste equipment and facilities have very industrial characteristics, through artistic processing into sculpture sketches.

2. Eco-brick of recycled building aggregate

The recycled building aggregate ecological brick is used in the hard pavement of the West Ten Winter Olympic Plaza project. The brick is made from the construction waste dismantled by the project, and meets the requirements of JC/T422-2007 technical specification of "Non-sintered Waste Tailings Brick". The recycled building aggregate ecological brick is paved and reused in the West Ten Winter Olympics Plaza. The total area is about 20,000 m2, the replacement rate of recycled aggregate is 70%, and the compressive strength is more than 35 MPa.

If you had to do it again?

The bottom of the chimney in the site is 9 meters in diameter and 90.5 meters in height. Influenced by the surrounding environment, it does not have the conditions for demolition by blasting, it can only adopt manual and mechanical construction methods. Because of the tense construction period, in order to reduce the construction difficulties caused by the traditional demolition methods and the high uncertainty of the construction period, it organizes innovative research and initiates "Tongtong", green demolition technology of tall buildings with integration of demolition and demolition.
Mainly hang a number of steel structure portals on the wall of the structure, the outside of the portal is a safety guardrail, the inner testing wire rope is woven mesh locking each other, the plane is laid with wooden boards, for sealing protection measures, the top is covered with springboards, forming an operation platform. Using manual and hydraulic forceps from top to bottom, the concrete on both sides of the portal frame is dismantled by rubbing teeth in opposite direction. A circle around the structure, the height of demolition is 200 mm, and the height of demolition is about 2 meters per day. The slag is poured into the enclosed space inside the structure from the platform crevice, and finally cleaned up by the ground machinery. Every demolition to a certain height, with the change of the diameter of the structure, the linkage tension between the steel rope and the distance between the portal frames is realized, and the size of the platform is fine-tuned to ensure that the size of the construction platform is appropriate. Through this innovation, the safe and green demolition of high-rise buildings has been realized, and the time limit for the project has been met. After practical testing, the developed "a kind of concrete chimney manual demolition operation platform" has been patented, and the green demolition construction method of concrete chimney under special environment has been certified by the Ministry of Metallurgy.

The dining environment is good, and there are Muslim Restaurant and other special areas, which greatly meet the dining needs of all groups.
After visiting Shougang Park, President Xi Jinping fully affirmed the acceleration of planning and construction of the northern area of Shougang Park to build a new landmark for the capital city renewal in the new era. Vice Premier Han Zheng of the State Council affirmed that Shougang Park was a "benchmark project for urban renewal". On August 26, 2017, President Bach of International Olympic Committee visited Shougang Industrial Park and said, "Shougang Office Park of Beijing Winter Olympic Organizing Committee revitalizes the old industrial relics. The protective transformation of Shougang Industrial Park is a great idea. It turns the old industrial buildings such as factory buildings and blast furnaces into sports and leisure facilities, as well as a museum. It is an exciting way for people to remember the history of Shougang, Beijing and China. This concept can be said to be the leading one in the world. It has provided an excellent demonstration. If you want to know how the Olympic Games can change the development plan of a city, a region or even a country, please look around and have a look at this exemplary Shougang Park. "

Product category :

Because of the limitation of the whole land use, the landscape greening area can not meet the requirement of greening rate. Vertical greening curtain wall is used to improve the greening structure, increase the total green amount and leaf area, expand the greening space, increase the green amount and greening coverage, and improve the overall greening level of the city. Vertical greening of wall surface is adopted in this project, which is beautiful, waterproof, super thin, long life and easy to construct without skeleton.

Making full use of the advantages of vertical greening curtain wall technology, saving the area of regional construction land, improving the green coverage, making comprehensive use of urban space, greening and beautifying the environment, has inestimable social and economic benefits. According to the calculation, the economic benefit of using this construction technology is 400,000 yuan less than that of traditional curtain wall. Vertical gardens are inexpensive, but they can bring fresh greenness to public and private space, reduce the cold feeling of the city, and their advantages are becoming increasingly obvious.
