The invention belongs to the technical field of soil test, and in particular relates to a novel triaxial test soil sample preparation system. The novel triaxial test soil sample preparation system comprises a compaction device, a sample striking barrel, a side-to-side clamping ring, a barrel opener and a planing brush. The sample striking barrel can be effectively fixed by the compaction device, and a striking hammer rod can be effectively controlled by the compaction device to be maintained perpendicular. The striking hammer rod is provided with scales, so that the height of a soil sample can be observed in real time. The inner wall of the sample striking barrel is coated with high-strength super-hydrophobic paint, so that the adhesion of water and soil particles on the wall of the sample striking barrel can be effectively reduced, and the barrel opening success rate can be greatly increased. Two convex rings are arranged on the outer side of the wall of the barrel and matched with the side-to-side clamping ring. The side-to-side clamping ring adopts a symmetric semicircular structure. The barrel opener is applicable to the sample striking barrel, the trivalve sample striking barrel can be opened by utilizing an identical force, the damage of the soil sample caused by non-uniformity of the stress when the barrel is opened can be avoided, and the barrel opening success rate can be increased. The diameter of the planing brush is identical to that of the sample striking barrel, and short steel wires are distributed on the surface of the planing brush. By adopting the novel triaxial test soil sample preparation system, the precision and efficiency for preparing a triaxial test soil sample can be effectively improved, and the barrel opening success rate can be increased.
