Application Research On Safety Management Of Earthquake Collapse Building Rescue Based On Wood Support System

China is one of the countries with the most serious earthquake disasters in the world,and also one of the countries with more earthquake casualties in the world.Earthquake lead to many secondary disasters,among which the collapse of buildings is the main reason for people being trapped and buried.There is a risk of secondary collapse of collapsed buildings.When rescuers are searching and rescuing,it is necessary to carry out safety management on the rescue site,that is,to support the rescue passage and protect the rescue working space,so as to solve the secondary injury of trapped people and the safety problems of rescuers themselves that may be caused by secondary collapse.This paper is aimed at the actual needs of rescue workers for wood support technology in the rescue of earthquake collapsed buildings.According to the relevant standards and specifications,this paper studies the rescue cases of earthquake collapsed buildings.There is no uniform and standard design and use procedure for wood support technology in the rescue of collapsed buildings,so this paper summarizes the experience of Chinese rescue team participating in IEC assessment.At the same time,we conducted earthquake rescue team training,drills and trainee training at the Kunming Training Corps.The reference documents,guidance documents and team experience will be researched and innovated in actual combat training,so as to realize the standardized application of wood support technology in earthquake collapse building rescue scenes from scratch.This paper has carried out the following aspects of research: first,this paper summarizes the application of wood support in earthquake building collapse rescue,which is based on the collapse form of earthquake-collapsed buildings,people’s living space and potential risks,and the safety management of rescue site.At the same time,this paper studies the design standards,design points and system strength of the application of wood support technology in collapsed building rescue.Second,fourteen kinds of support types are designed systematically,including three types of vertical support,horizontal support and oblique support.These support methods are mainly used in four types of rescue scenes: broken doors and Windows,broken floor beams,broken wall columns and broken corridors.Finally,combining with the four application scenarios in the rescue of earthquake-collapsed buildings,the division of labor,equipment and basic principles of the wood support system in the application are studied in the actual combat training.At the same time,repeated actual combat training in daily training and training,focusing on the standardized and standardized application of wood support system in four types of scenes from the aspects of material bill,application program and application key points.It solves the problem that the rescue team has the application need and guidance plan of wooden support,but there is no specific application program and standard application method.In two years of practical training,the application of the wooden support technology has successfully completed all kinds of teaching and training and various kinds of drills.At the same time,the project of Kunming Training Corps,which focuses on the standardized application of wood support technology studied in this paper,has successfully been completed and won the praise of experts in the same trade.
