01 Thermal insulation construction process
_span8p2p _span8p2p Known as the "passive house with high thermal insulation", it can save more than 80% of energy compared with traditional buildings. The outer windows of the project use hollow glass, which can effectively block the heat exchange between the indoor and the external environment. Through the use of high-efficiency fresh air technology, it is possible to improve the air while maintaining the indoor constant temperature, which is between 18 to 24 degrees Celsius, which is the most suitable for the human body. It can truly achieve the effect of warming in winter and cooling in summer without heating in winter and air conditioning in summer.
02 The "sun room" built in seven days
is regarded as the "light building integrated photovoltaic house" by the Beijing National Solar Energy Group The wall replaces the traditional cement wall, and the annual power generation is expected to reach 75,000 kWh, meeting 30% to 40% of the electricity demand of the building. The project is also known as the "building block assembly house". The 410 steel structural components and 197 roof unit blocks used in the construction are prefabricated in the factory and assembled like building blocks, which only takes seven days and nights in total. Prefabricated construction is not only fast, but also can effectively reduce air pollution and construction waste emissions during construction, and reduce environmental pollution such as dust and noise.
03 Construction site construction waste recovery and recycling technology
_span8 Span5 Span5 Span5 Span 5 Span 8 The integrated engineering waste treatment equipment is mainly used to treat the construction waste generated during the construction of various projects such as housing construction, public construction, and municipal construction. China Construction First Bureau created the first quantitative forecasting platform in the country, which can sort and recycle 70% of construction waste. It is a national key research and development plan subject of " 13th Five-Year ". The equipment has the characteristics of strong mobility, modular combination, strong site adaptability, and low noise. It can be classified according to the original functions and availability of construction waste, accurately analyze the amount of waste of different building types, provide a data basis, and realize construction waste From the building to the building.
04 "4233" ecological restoration and management construction mode
ranked first in the national third batch of grassland, sand, forest, and water fields in Wuliang Lake, grass, mountain, and water The country’s largest pilot project for ecological restoration of landscapes, forests, fields, lakes and grasses. The desert control area ranks first among similar projects in the country. The ecological restoration area is about 14,700 square kilometers. This is the first case.
The builders of China Construction First Bureau adopted the "4233" ecological restoration and management construction model, which is a four-step standardization desert management, forest and grass restoration two artifacts, three-step mine management, and seawall renovation. Desertification control stabilizes sand dunes, forest and grass restoration improve regional soil and climatic conditions, and consolidate sand control results; through the restoration of the mine environment to curb surface water and soil loss, ensure vegetation coverage, and reduce regional soil desertification; restore water ecology through seawall governance to ensure water safety . The governance of various business forms takes multiple measures and complements each other, and finally realizes the harmonious coexistence of man and nature in the basin, repairs the kidney of the Yellow River, and helps the ecological protection of the Yellow River basin.
