摘要
对六安市污水管网建设中爆破顶管施工工艺进行了介绍,根据现场的条件提出浅埋小截面巷道掘进光面爆破施工方案。该方案将爆破成硐与顶管施工相结合避免了拆迁工作、减小了环境污染、加快了工程进度、节省了项目投资,对类似工程有很好的借鉴、指导作用。
This paper briefly introduced the blasting of digging top tunnel in the construction of city sewage pipe network in Liu'an city. The program of shallow burying-small section tunnel excavationsmooth blasting was adopted based on the site conditions. The adoption of this program combined the blasting with the top pipe construction, avoiding the work of relocation, reducing environmental pollution, speeding engineering schedule and saving project investment. This project is value to similar engineering work.
