The high efficiency experiment technology of chemical explosion in underground closed structure

Accroding to the technology need of high efficiency chemical explosion in underground steel fiber concrete lining chamber,the methods of structure engineering and technological designing were used.In order to do repeatability chemical explosion in same chamber,a pipe was designed for persoonel and materials passing in steel fiber concrete blocking structure.The different structures were designed for resisting blast load and experiment encapsulation,it make the experiment safe and reliable.After chemical explosion,for quick eliminating toxic gas in experiment chamber and rock near experiment site,the high-pressure gas was filled into closed chamber,the subsequent experiment was prepared continuously.It took about three days for preparing complex structure chemical explosion by using technology which were designed in this paper.
