Research On Intrinsic Safety Management Of Smart Construction Sites In Construction Enterprises

In recent years,with the continuous development of the construction industry,the increase in engineering volume and complexity,the state has put forward higher requirements for the safety management level of construction sites.In order to adapt to the requirements of building construction safety management under the new situation and to explore new safety management models,it is necessary to use advanced technical means to control the full cycle of building construction.As a new way of transforming traditional safety management methods,intelligent construction site safety management informatization has gradually entered more and more construction sites.This article explores how to use advanced science and technology to promote the construction of intrinsic safety in smart construction sites by introducing relevant theories of intrinsic safety.This provides support for the transformation of the safety management model to the direction of intelligent,essential,and systematic.First of all,this article sorts out the related concepts of the intrinsic safety of smart construction sites,and defines the intrinsic safety management of smart construction sites.On this basis,a smart construction site intrinsic safety management structure model including personnel management,mechanical equipment management,on-site monitoring and early warning,and process control management has been constructed.In the context of smart construction sites,a new definition is given to the model,and the model structure is analyzed,which provides a theoretical basis for the study of the full text.Secondly,the 20 key elements of the intrinsic safety management system for smart construction sites were screened out using methods such as Delphi and DEMATLE.Based on the core technology and equipment of the smart construction site,the framework of the intrinsic safety management system for the smart construction site has been constructed.The framework defines the main content of the 20 key elements of the system and the working principles of functional applications,and provides a reference for the information construction of the intrinsic safety management of smart construction sites.Then,this paper studied the evaluation method of the intrinsic safety of smart construction sites and established an evaluation model of the intrinsic safety.The intrinsic safety of smart construction sites is divided into initial level,simple level,standard level,mature level and excellent level,and the specific definitions and characteristics of each level are defined.Then an evaluation index system including 4first-level indicators and 20 second-level indicators was constructed and the index evaluation standards were formulated.Through the use of C-OWA method and unascertained measurement model to evaluate the level of intrinsic safety management,and use the intrinsic safety management priority improvement area method to determine the priority improvement order.Finally,this article analyzes a smart construction site project in Xi’an Metro and determines the intrinsic safety level of the project as a standard level.Through evaluation and improvement analysis,it helps the company to correctly grasp the actual construction and implementation of the various elements of the system,and clarify the specifics.The improvement direction provides a reference for the construction and continuous improvement of the intrinsic safety management of smart construction sites.
