[0003] After searching, the prior art disclosed a Chinese patent application numbered CN 214997625 U, which discloses a tunnel advanced geological prediction device. To address the problems of easy sample dropout and poor water-blocking performance raised in the prior art, the following solution is proposed, comprising a sampling sleeve and a casing. The inner wall of the sampling sleeve is provided with a sampling mechanism, and the sampling mechanism includes a first semicircular sampling plate mounted on the outer wall of the bottom of the sampling sleeve, a rotating column rotatably connected to the outer wall of the top of the first semicircular sampling plate, and a second semicircular sampling plate mounted on the outer wall of the bottom end of the rotating column. However, the following defects still exist:

[0004] (1) When sampling, the sample entrance is small and the resistance encountered when inserting into the soil layer is large, resulting in low sampling efficiency and poor sample quality, which can easily cause inaccurate geological forecasts and endanger construction safety.
