Deep Buried Undisturbed Sand Sampling Technique

Abstract:

Considering the feature of the sand samples being easily disturbed, a swivel type rotary-push sand sampler is developed. Quality control of the samples is carried out in regard to each procedure in the entire process of recovering, taking out and preparation of the sample. It offers a solution to the technical problem of obtaining the deep buried undisturbed sand sample encountered in the Water Transfer Project from the South China to the North China and the Three Gorges Project.
