袖阀管注浆在桥涵台背填土加固中的试验研究

Experimental Study of Sleeve Valve Pipe Grouting in Bridge&Cul-vert Abutment Backfilling Reinforcement

文章结合对玉铁高速公路桥涵台背填筑质量的调查分析,在现场袖阀管注浆实体试验工程试验研究的基础上,提出了桥涵台背填土袖阀管注浆加固设计方案、施工工艺、质量控制与检测方法及评价标准。

In combination with the investigation analysis of bridge ＆ culvert abutment backfilling quality of Yutie Expressway, and on the basis of on-site experimental studies of sleeve valve pipe grouting body experiment engineering, the article proposed the reinforcement design plan, construction techniques, quality control, testing methods and evaluation standards of sleeve valve pipe grouting for bridge ＆ culvert abutment backfilling.
