The construction industry is an industry with frequent safety accidents. Due to the disadvantages of complex management personnel, dirty environment and cross-operation of multiple types of work, there are widespread characteristics such as extensive management and scattered construction site.
With the rapid development of the construction industry and the continuous expansion of the industrial scale, the original management mode has gradually shown its drawbacks, and the traditional construction site management mode has not met the requirements of the sustainable development market. Focusing on the rapid development of the Internet, the information age of the construction industry has arrived. Smart construction site has realized the informationization and refined management of the construction industry through the new generation of high-tech information technologies such as mobile Internet, Internet of Things, cloud computing and big data, which truly embodies the safe production and scientific management.
Smart construction sites can realize intelligent monitoring of elements, forecasting and alarming, sharing of work data and real-time collaboration through information technology, which can effectively help enterprises improve management efficiency, reduce labor costs and ensure construction safety.
The development of smart construction site not only stems from policy orientation, but also is the inherent requirement of construction enterprises' own information construction. On the basis of information technology, the smart construction site builds an information system supporting site management, interconnection and cooperation, intelligent decision-making and data sharing around the whole life cycle of the construction project, and firmly grasps the five elements of "people, machines, materials, law and environment" in the construction site.
Focusing on the work requirements of "controlling risks, eliminating hidden dangers and preventing disasters", data visualization technology focuses on key projects and important links, and concentrates time and energy on applying data visualization Web configuration to construction management. Hightopo visualization ensures the safety of building construction, curbs frequent accidents, and helps the industry's safety production situation to improve steadily.
Combined with BIM three-dimensional modeling, the whole process of site leveling, foundation preparation, backfilling and other stages is digitally twinned, and a Web three-dimensional construction management visualization platform is realized, so as to estimate the project cost and control the budget.
The three-dimensional models of buildings and construction sites are linked with the construction progress, and integrated with information such as construction resources, safety quality and site layout. It integrates various systems such as building construction progress, equipment worn by construction personnel and safety management. , to achieve visual expression. VR, handheld or fixed touch terminals can all support it, reducing the intermediate links of information transmission, ensuring the timeliness and timeliness of information transmission, and unifying project standards.
With the effect of 3D configuration, it can give an alarm for dangerous operations such as tower crane collision, display the cross operation of tower crane, and ensure the safety of tower crane operation to the greatest extent.
The system can independently set warning type information according to the construction points, simulate the whole process of earthwork excavation, avoid the defects such as uneven slope, uneven foundation and debris accumulation before backfilling, and repair with excavation, speed up the construction process and improve the quality of engineering work.
Based on UWB positioning base station, combined with BIM technology, the comprehensive layout of the floor is optimized through on-site lofting, and 3D virtual roaming is adopted for the feasibility of floor positioning, so as to determine the position of the penetration welding spot between the floor and the steel beam, coordinate installation, ensure the reasonable layout, and realize the effect of zero demolition and modification and one-time optimization.
The research and application of intelligent site management can effectively deepen the management mode of construction enterprises, improve the strength of enterprises, change the traditional site management mode, be more refined, exemplary and streamlined, and achieve the effects of management optimization, clean environment, standardized personnel and responsibility to people. Open up the data link from front-line operation to remote supervision, realize intelligent and internet management of labor, safety, environment and materials, and improve the management level of lean production on the construction site; Prevent the occurrence of safety accidents, investigate the responsibility of safety accidents, and make site management more in line with the needs of managers.
