深埋砂层取原状样技术研究

Deep Buried Undisturbed Sand Sampling Technique

摘要:

针对砂（上）样易扰动的特点，研制了ＨＹＳ－１型单动回转压人式取砂器，并从钻取、退样、试样制作的全过程各工序对取样质量进行控制，解决了南水北调和三峡工程中深埋砂层取原状样的技术难题。

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.
