基于注浆加固工艺的道路拓宽施工关键技术研究OA

By discussing the application of grouting reinforcement technology in highway reconstruction and expansion projects,an elaboration was made for the widening process of new and old roadbeds based on geopolymer grouting process.Geopolymer grouting reinforcement technology was used to increase the utilization ratio of old roads,reduce road excavation,construction and any adverse impact on local environment.In Beijing-Qinhuangdao expressway project,geological radar,deflection detection and other indicators were adopted to check the effect of applying the grouting reinforcement technology to the road widening works.The results show that the technology effectively improves the foundation stability and bearing capacity,meets the settlement demands,lead to significant social and economic benefits.
