Study On Identification And Control Of Hazard Sources In Construction Safety Production

Production safety has always been an important basis for the progress of human society and a major factor in ensuring the stable development of the national economy.People need to pay more attention to the harmony between human and natural environment under the condition of adhering to the people-oriented concept of safe production.Among many industries,the construction industry is one of the industries with the largest number of employees and the most complex operating environment.The production of construction projects is related to the safety of thousands of people's lives and property.In order to protect the people in the construction industry and follow the scientific development concept promoted by the state,people need to master the hazard source state in the construction project and control it.This paper revolving around a deep foundation pit excavation of a construction project in the process of the dynamic identification and control of the foundation pit collapse hazard to systematically study,analyses of the process of the construction environment,the operating personnel,machinery and equipment,construction technology and construction materials,using systematic analysis method to complete the work on the process of hazard identification,master the regular pattern of it,complete the hierarchies of hazard,and formulate concrete measures for its control.This paper is divided into five parts:The first part elaborates the research background,significance,research object,method,main content and framework of identifying and controlling the risk source of deep foundation pit construction.The second part is the theory.In this part,the concept,application direction and corresponding laws and regulations are analyzed from the perspective of project construction safety production management.The viewpoints of domestic and foreign scholars are expounded from the perspective of safety accident cause theory and modern system safety theory,indicating the importance of hazard source identification.The third part is based on the deep foundation pit construction process to develop the hazard identification,indicating the identification content,method,process,results,as well as from the initial identification and dynamic identification point of view to develop the hazard identification analysis at different levels.The fourth part is to carry out hazard source control in combination with a deep foundation pit project of a project.This part understands how to control hazard source from the perspective of principles,processes and methods,providing guarantee for the construction safety of deep foundation pit project.The fifth part is the conclusion part,which expounds that the hazard source identification of deep foundation pit project construction is related to the probability of accident.Hazards of the produce is caused by many factors,through the initial recognition and identification of dynamic form of hazards are identified,by using intuitive experience and method of hazard analysis and discussion,finally listing the possible hazards and giving the corresponding control strategy,so,as to really reduce the probability of building engineering construction safety accident and achieve the goal of safe production management.
