Abstract: The redbed soft rock samples from the Humaling Tunnel of LanYu Railway Project is Dingxi City, Gansu Province have strong slaking properties and they are disintegrated quickly during the sample preparation process. A new sample preparation tool consisting of nylon sample holding tube and sample grinding clamp was developed to isolate the sample from the water in sample preparation process. This device can improve the quality of the test sample.
