摘要
The present invention provides a method for tackling the repelling of hammering during pipe pile driving, which is of simply structure and can be carried out easily. The technical scheme of the present invention comprises: When repelling of hammering occurs in the process of piling through a sand layer, drill holes downwardly around and/or inside the pipe pile, and jet high-pressure water to the sand layer below to cut and disturb the sand layer, which consequently decreases the soil resistance to the pipe pile and increases the driveability. The present invention is applied to geotechnical engineering.
