摘要
Abstract
The construction project of pile foundation engineering is prone to engineering quality accidents due to the development of karst(soil)caves.To ensure the safety,quality,progress,and cost control of pile infrastructure,mature sleeve valve pipe grouting treatment technology is selected in practical work.By analyzing geological survey data,the development area of karst caves can be identified,and the positions and depths of grouting holes and exhaust holes can be reasonably arranged.Suitable grouting parameters and processes can be selected to effectively solve the hazards caused by karst.This method can be used for the treatment of karst cave foundations of a certain scale in karst landform areas.关键词
