入岩判定错误桩补救施工技术

Inserted Rock Decision Error Pile Remedy Construction Technology

工程桩地质勘察入岩判定错误,导致桩底持力层夹杂0.9m厚强风化岩层及残积砂质岩层,为保证桩身承载力,确保桩身不下沉,采取了水洗置换注浆法对工程桩进行了补救,经现场大应变检测,桩身承载力满足要求。

Because of inserted rock decision error of engineering piles,the bearing stratum of the pile bottom has 0. 9mthick strong weathered rock stratum and eluvial sandy rack stratum. To ensure load capacity of the pile,the remedy measure of washing replacement grouting method is taken. By big strain inspection,the load capacity of pile satisfies the requirement.
