小导管注浆与重力式抗滑墩加固浆砌片石挡墙技术

Soil-nailing wall technologies of ductule grouting and gravity-style anti-sliding pier reinforcing mortar rubble

以广东深圳某高速公路为例,结合注浆技术加固土体的原理,分析了挡墙的变形原因,介绍了小导管注浆结合抗滑支墩的加固技术,阐述了施工过程中的技术要点,结果表明:该技术在加固高浆砌片石挡墙中有很好的效果。

Taking Guangdong Shenzhen highway as an example, combining with soil reinforcing principles of grouting technology, the paper ana-lyzes soil retaining wall deformation causes, introduces reinforcing technologies of ductule grouting integrating with anti-sliding bearing pier, and describes technologies points of construction process. Results show that ： the above-mentioned technology has achieved great effect in reinforcing mortar rubble soil retaining wall.
