| A liner assembly for use in a soil sampling system comprises a thin sheet of flexible plastic that can be laid flat for shipping and rolled into a cylindrical shape with overlapping edges for use as a liner. The rolled sheet can be inserted into a soil sample tube to line the sample tube during soil sampling operations. A wedge assembly comprising a split holding ring and a wedge ring holds the liner in place at the bottom of the soil sample tube. After the soil sampling system is advanced into the subsurface to collect a soil sample, the soil sample is removed by removing the cutting shoe from the sample tube and sliding the rolled liner sheet out the bottom end of the sample tube. The liner sheet can be unrolled to access and remove the soil sample. The liner sheet can be reused after removing the soil sample. | ||||||
