综合爆破技术在渠道开挖中的应用

Integrated Blasting Techniques Applied in Channel Excavation

以南水北调中线工程焦作段溃城寨河渠道倒虹吸石方爆破开挖为例,基于爆破理论探讨综合爆破技术在渠道开挖中应用的可行性和关键技术问题,提出了"分区分爆"的综合爆破方法。实践表明,在石区渠道开挖过程中,由于实际施工条件的限制及施工进度、质量的要求,多种爆破方法的综合应用是加快施工进度和保证施工质量的有效措施。

Taking the excavation of rock blasting as the research object, which belong to the collapse walled city river inverted siphon in Jiaozuo stage in the middle route project for South-to-North Water Transfer, based on blasting theories to explore the feasibility and key technical problems for the comprehensive blasting technology in the channel excavation, proposed a “partitions explosion” integrated blasting method. Practices shows that, due to limited engineering conditions and require-ments of engineering progress and quality, integrated application of several blasting techniques is an effective measure to speed up the progress and ensure quality In the process of stone area channel excavation.
