Below, go into these projects that explore the application of green low -carbon construction technology together ~

Qingdao Metro Line 6 project

"Optimization of TBM excavation parameters and secret digging station support systems"

The Department of Foundation (China Construction Basic) has led the Qingdao Metro Line 6 project. Since its implementation, it has cooperated in depth with Shandong University and Beijing University of Technology. Research on the research on the intelligent optimization of the hard rock digging parameters and the active support application of large span stations, etc., optimized the excavation parameters of the first dual shield TBM of the China Construction System and the support system of the dark excavation station, effectively reducing the wet spray concrete The amount of steel bars of the dosage, the use of the reinforced station, and the power consumption of TBM have improved the efficiency of excavation and effectively reducing carbon emissions.

The project also refers to the form of coal support to introduce a pre -stamping anchor support system to change the original design of 0.5m × 0.5m plum blossoms to arrange anchor rods to 0.8m × 0.8m, saving 37.5%anchor rod consumption.

Zhonghai Heshan Grand View Project

Passive ultra -low energy consumption building

The Zhonghai River Grand View project undertaken by Zhonghai Group is located in Hohhot, Inner Mongolia. It is the largest ultra -low energy residential demonstration project in the severe cold area of ​​Inner Mongolia. The total construction area of ​​the project was 165,500 square meters, of which 131,700 square meters were built in accordance with the national ultra -low energy design specifications and technical systems, becoming a pilot case for passive ultra -low energy consumption buildings at home and abroad.

△ Ultra -low energy consumption building technical characteristics

Ultra -low -energy buildings refer to architectural technology that adapt to climate characteristics and natural conditions, using passive technical means to greatly reduce the demand for active heating in the building, improve energy equipment and system efficiency, and provide a comfortable indoor environment with less energy consumption. architecture.

△ Reduce the heat sink and structural hot bridge through the simple architectural shape design, and reduce the heat load. The design of shallow into the deep surface and wide surface, make full use of natural glory and light, meet the needs of getting hot solar radiation as much as possible in winter

According to the characteristics of ultra -low energy consumption technology, the project innovation and application of the over low energy design technical standards and energy consumption solutions in the severe cold areas, adopt a performance design method to keep the exterior wall insulation, gas -hot bridge treatment, energy supply methods, energy supply methods, energy supply methods, energy supply methods, energy supply methods, and energy supply methods The combination of other technologies, optimize various technical measures, and achieve energy -saving effects under low -cost investment. Compared with the traditional heating method, the project uses a new air -cooling source all -in -one machine, which makes full use of air to heal, and uses the electricity of winter thermal power and abundant wind power in the cold area. While normal temperature and carbon reduction, heating costs are reduced.

△ New Wind Integrated Machine Physical Model

During the construction process, the project adopts innovative construction technology such as pull -type aluminum mold, hot bridge technology, gas -deficit technology, and band -band -frame embedded passive window installation process, forming an ultra -low energy -consuming building construction process and quality The management technology system ensures convenient construction and improves construction quality.

World Dingke Community · Haiyuntian Project

Create "green building Samsung" and "ultra -low energy consumption" building model

The World Dingke Community · Haiyuntian project undertaken by China Construction Second Bureau, closely linked to green, low -carbon, and intelligent brand positioning during the construction process, actively advocated energy -saving production methods, and created "green construction Samsung" and "ultra -low energy consumption" Building models to build a clean and beautiful home.

△ The World Dingke Community · Haiyuntian Project

The project is guided by the technical standard of "Green Construction Samsung", and is committed to creating an integrated shared intertwined garden with "safe and durable, healthy and comfortable, convenient life, resource conservation, and livable environment".

△ Eight ultra -low energy consumption technical schematic diagrams

The project also draws on the design concept of the "sponge city", and has new technologies such as rainwater reuse systems, high -efficiency VRV air -conditioning systems, and local solar heat water systems. Among them, rainwater reckles are collected and utilized through water transparent road surface, rainwater collection and utilization, and rainwater infiltration process, so that the rainwater runoffs of the site to achieve source purification, source stagnation, and source of the source, reduce rainwater runoff, and reduce surface source pollution caused by rainwater scouring. Energy -saving and environmental protection indicators of carbon reduction and emission reduction are completed, making the living environment more comfortable, healthier, and more economical.

Shenzhen Construction Engineering Quality Supervision

And testing experimental business building renovation project

Green low -carbon technology helps improve the energy efficiency of construction energy

Shenzhen's construction engineering quality supervision and testing experimental business building has been completed for more than 20 years. With the time migration, the level of energy conservation and emission reduction of construction is urgent. China Construction Technology explores the technical system of green transformation of public buildings in the summer and warm and winter warm areas. It conducts passive ultra -low energy consumption transformation of the building. Compared with the overall demolition and reconstruction method, this project not only saves the cost of building security, and can also be available every year. Save electricity and reduce carbon emissions, which has become a benchmarking project for green transformation in South China. △ Shenzhen Construction Engineering Quality Supervision and Testing Experimental Building Reconstruction Complete Map

Shenzhen is located in the summer heat and winter heating area. The east -west exterior wall is heated. The project's three -dimensional greening can effectively reduce the surface temperature of the outer wall and then reduce the energy consumption of air conditioning. Considering the construction conditions of the facade, the project was selected for three -dimensional greening on the west side of the north building, with a green area of ​​about 340 square meters.

△ Vertical green wall of the west facade

The project uses a solar photovoltaic energy system in the building roof. The installed capacity is 30 kW and the annual power generation is about 30,000 kilowatt -hours.

△ Roof solar use

This project uses roof greening, vertical greening, aluminum-plastic co-squeezing Low-E hollow glass window, perforated aluminum plates, solar photovoltaic power generation, air source heat pump thermal water system, LED lighting, first-level energy efficiency multi-online system, new wind heat heat heat Green and low -carbon technology measures such as the recycling system technology are expected to have a total annual electricity saving of about 267,000 kilowatt -hours, reducing carbon emissions by 209.6 tons.
