Supervision practice of blasting demolition of prestressed cable-stayed bridge with single tower and single cable surface
In order to make the downtown area of a cable-stayed bridge with a single pylon and one cable plane blasting demolition work carried out smoothly,the blasting safety supervision unit entered the site in advance and provided professional technical services for many aspects of the pre-blasting construction to ensure successful blasting.In the early stage of blasting construction,the blasting safety supervision unit proposed feasible suggestions for the establishment and testing of the cable-stayed bridge model,safety protection design,and vibration monitoring design,and deeply involved in the blasting design and construction unit of the cable-stayed bridge instability collapse model test,comprehensive consideration of the risk of blasting hazards,the development and efficient use of low visibility in complex environments under the all-round three-dimensional real-time intelligent blasting safety alert monitoring and search system and other processes.Cable-stayed bridge model blasting test for cable-stayed bridge solid blasting construction provided technical reference so that the blasting construction unit can more comprehensively consider the risk of blasting hazards,to avoid some of the economic losses and negative impacts.In addition,the application of vigilance monitoring and search system to promote the integration of high-tech means and blasting projects.In view of the early entry of this blasting project supervision unit,which is conducive to the smooth implementation of blasting,and provides a meaningful reference for the subsequent blasting supervision of similar projects.
