近年来,油田工程改造项目呈明显地上升趋势,特别是在较大改造工程中,经常遇到需要拆除大型混凝土及钢筋混凝土基础的情况。由于这些体积庞大的基础多位于室内,不能使用普通的爆破拆除技术,这样就给使用机械、人工破碎施工带来很大困难。随着静态爆破技术的不断成熟,在有限的时间、空间里完成大型基础的拆除施工成为可能。 In recent years, oilfield reconstruction projects showed a clear upward trend, especially in the larger renovation project, often encountered the need to dismantle the large concrete and reinforced concrete foundation situation. Due to the fact that these bulky foundations are mostly indoors, ordinary blasting and demolition techniques can not be used, which poses great difficulties for using mechanical and manual crushing construction. With the continuous maturation of static blasting technology, it is possible to complete large-scale demolition and construction in a limited time and space.
