Smart construction site: cover the safety network for engineering construction

"Smart construction sites refer to the application of information technology in the construction site to reduce the dependence on the construction site. Smart construction sites require the support of emerging information technology, including perception, transmission, computing, memory, and analysis of several categories. We familiar with big data and cloud computing we are familiar with , Geographical Information System, etc., are the key support technologies of smart construction sites. "Ma Zhiliang, a professor at Tsinghua University, said that many smart construction site -related information systems have basically covered the main people, machines, materials, laws, etc. on the construction site. Management objects, as well as the main management of planning, progress, cost, quality, etc., and have been applied in the actual process.

In July 2020, the National Thirteen Ministry and Commission jointly issued the "Guiding Opinions on Promoting the Coordinated Development of Intelligent Construction and Construction Industrialization", stating that "to increase the application of intelligent construction in all aspects of engineering construction and form an intelligent construction industry with the integration of the entire industry chain System, improve engineering quality, safety, efficiency and quality ".

How does smart construction sites ensure safety in today's engineering construction? On June 30, at the midsummer, a reporter from the Science and Technology Daily came to Tongzhou, Beijing, and visited the two major projects under construction in Beijing's sub -center.

On the construction site of the Beijing East Sixth Ring Road Reconstruction Project, the Smart Construction Site shows all the operating processes of the "Jinghua" large shield structure.

"The project through the in -depth integration of advanced information technology such as cloud computing, the Internet of Things, artificial intelligence, and building information models with construction technology. Advanced technologies such as speed measurement illegal capture, and a construction site safety supervision system, which has greatly enhanced the safety management capabilities on the spot. At present, it has successfully achieved 943 days of safety production. "Yang Zhe, chief engineer of the Beijing East Sixth Ring project in China Railway, said At present, the "Jinghua" shield machine has successfully crossed the 17 secondary and above risk sources such as Tongyan Expressway, a comprehensive transportation hub of the urban auxiliary center, and the Jingha Railway. The new record of the rim in the diameter shield machine has achieved the goal of essential safety and zero casualties and zero accidents.

Not far from the East Sixth Ring Reconstruction Project, it is the comprehensive transportation hub project of the Beijing Urban Sub -center Station, which is under construction. The underground construction area is 1.28 million square meters and the ground building area is 1.39 million square meters. It is the largest underground transportation hub in Asia. On the large screen of the comprehensive transportation hub information command hall of the Beijing Urban Deputy Center, the intelligent production and control platform shows the various types of information of the project operations in real time, including safety supervision, safety hazards, risk management, video surveillance and emergency management.

China Railway Construction Industry Group Beijing Urban Sub -Central Centers Comprehensive Transportation Hub project has the deepest part of the foundation pit of 32.5 meters, and the safety management situation of foundation pit is severe. Song Xiao, chief engineer of the comprehensive transportation hub project of China Railway Construction Industry Group, told reporters that the project department adopts the foundation pit automation monitoring system to master the foundation pit deformation data at any time to provide a basis for the safety management of the project department.

On the intelligent production and control platform, the position of the main managers can be observed in real time. "When working on site safety, quality technology and other managers, wearing smart helmets to carry out work. The helmet should have effective functions such as positioning, SMS, voice intercom, video interaction, recent trajectory, automatic AI recognition, etc." Song Xiao said, intelligent The location and personnel of the hard hat detected, and then clearly understand the on -site distribution of workers through real -time data of the mobile terminal, and provide scientific on -site management and decision -making basis for project managers.

According to reports, as of June 30, the comprehensive transportation hub of the Beijing Urban Deputy Center Station has achieved a safe production of 943 days.

Experts believe that the smart construction site makes up for the lack and inefficiency of traditional regulatory methods, and the passive supervision is to active supervision, covering a safety net for the construction of the project, effectively protecting the safety and interests of the construction personnel, greatly improving the safety of the live safety, the on -site safety Management ability.
