摘要
采用定向钻法建造的某水库坝下涵管在运行几个月后即发生垮塌。通过现场勘察和理论计算,查明了事故原因,从施工工艺、管材选取、工程管理三方面对定向钻法的关键技术进行了深入探讨,提出了相关建议,证明了定向钻法在技术上的可行性,并给出了涵管的补救措施。
A new dam culvert diversion of reservoir was built by directional drilling, but only few months later the culvert collapsed. Through on-site investigation and theoretical calculations, it finds out the causes of the accident. And then this paper deeply explores the key technology of directional drilling method from the aspects of construction process, pipe selection and project management. Finally, the corresponding recommendations are put forward and it demonstrates that the directional drilling method is technically feasible. At the same time, the remedial measures of culvert diversion are proposed.
