Patent ID: 8429988

Claim:
A soil-cement sampling device, comprising: a first cylindrical tube having a top end and a bottom end; a second cylindrical tube positioned within the first cylindrical tube and removably connected to the first cylindrical tube; a plate arranged at the bottom end of the first cylindrical tube, the plate including an aperture extending through the plate and aligned with an open end of the second cylindrical tube positioned within the first cylindrical tube; and a seal arranged between the plate and the open end of the second cylindrical tube; wherein the second cylindrical tube, when connected to the first cylindrical tube, is configured to recover a soil-cement sample when the sampling device is inserted into recently mixed soil-cement before it hardens, wherein the seal prevents the soil-cement sample from entering a void formed between an interior surface of the first cylindrical tube and an exterior surface of the second cylindrical tube, and wherein the second cylindrical tube is configured for removal from the first cylindrical tube after the soil-cement has hardened.
