一种双液注浆型土钉在基坑支护中的应用

Application of Cement-silicate Double Solution Grouting Soil Nail in Pit Construction

针对深厚填土地层基坑开挖特点和传统土钉的不足,提出了一种水泥-水玻璃双液注浆型土钉,并在实际工程中应用,通过对比分析发现该种土钉具有安全、高效和经济效果明显的优点。水泥-水玻璃双液注浆型土钉为类似工程提供了一种新型基坑支护结构。

According to the properties of pit excavation in deep filling earth layers＇ and traditional soil nail＇ s defects, a cement-silicate double solution grouting soil nail was developed. The application of this new soil nail in pit excavation showed that it was a good pit excavation supporting structure in deep filling earth layer site, with high security, construction efficiency and economical benefit comparing to traditional soil nails. The cement-silicate double solution grouting soil nail was a good pit excavation supporting structure for the pit excavation in homologous earth conditions.
