高压旋喷注浆在桩端持力层的应用

Application of Highly Pressed Rotary Infusion of Concrete Serosity upon Supporting Layer of Piling Foundations

广惠高速公路C2标长湖小桥3#台1’#桩在施工完毕后进行检测,发现桩底存在溶洞,造成桩端持力层不符合设计要求,为保证施工质量,决定采用“高压旋喷注浆法”进行加固处理,取得良好效果。

Tests for pile 1# and 3# of C2 section in Changhu Bridge of GuangHui Expressway,some resolving caves are found under the lower end of the pile,which lead to failure of the supporting layer.To ensure the construction quality,we offer consolidation to it,using highly pressed rotary infusion of concrete serosity upon supporting layer of piling foundations and have obtained a satisfactory result.
