钻孔注浆技术在处理桥头路基沉陷中的应用

Application of Drilling Grouting Technology in Treatment of Bridge Head Subgrade Settlement

随着公路工程数量的日益增加,各种新的施工技术也层出不穷。在公路工程养护的过程中,对于桥头路基的沉陷处理极为重要,直接影响了行车的舒适度。钻孔注浆技术是甘肃省桥头路基沉陷处理的一种有效方式,其利用注浆设备向钻取好的孔洞内注入灌注液,并在注入的过程中不断搅拌,进而形成稳定的桩基,利用桩基来承载整体负荷,具有较高的稳定性。

With the increasing number of highway projects,various new construction techniques are emerging.In the process of road engineering maintenance,it is extremely important for the subsidence treatment of the bridge head subgrade,which directly affects the driving comfort.Drilling and grouting technology is an effective way to treat the subsidence of Qiaotou roadbed in Gansu Province.It uses grouting equipment to inject perfusate into the drilled hole,and continuously stirs during the injection process to form a stable pile foundation.The pile foundation is used to carry the overall load and has high stability.
