The Dock Cofferdam Demolition Blasting Technology Research And Engineering Application

The blasting for demolition of dock cofferdam is the last working procedure for dockconstruction after accomplishing the internal constructions. Comparing other blasting techniques,the blasting demolition technique has some characteristics, such as larger explosive of ignition,higher technique content, shorter time limit for a project, more potential safety hazard and limitedfactors and so on. There are so many accsidents happened in the progress of the blasting fordemolition from time to time that the blasting for demolition of dock cofferdam need beresearched profoundly for cutting down accsidents and improving this techinique.The following are the main researches：(1) Comparasion and Selection of the blasting schemes for demolition of dock cofferdamcould be carried out.(2) In the research for the principles of design for the web of the blasting for demolition ofdock cofferdam, the principles of design and blast parameters for the blasting for demolition ofdock cofferdam in different structure and working conditions would be gained.(3) In the research for the blasting demolition technique and safety protection, importantconstruction technology and quality and safety technological demand for the blasting fordemolition of dock cofferdam and safty protection and control technology for closed-in blastingin water would be researched.(4) In combination with the engineering cases of the blasting for demolition of dockcofferdam in zhongyuan and jinhaiwan, Application in Engineering for this blasting demolitiontechnique could be researched.
