结合几个工程实例.探讨了重点地段取水建筑物改建中的爆破问题,并就改建时部分拆除和全部拆除重建两种情况的技术难点进行了研究和实施。工程实践证明,所提出的解决途径是可行有效的。 Combined with several engineering examples, the blasting problems of water intake structures in key sections were discussed, and the technical difficulties of partial dismantling and total dismantling and reconstruction in reconstruction were studied and implemented. Engineering practice proves that the proposed solution is feasible and effective.
