Detection device for shear strength of film bag sand

The utility model provides a device for detecting the shearing strength of film bag sand, which comprises a press machine capable of displaying the current pressure value, the press machine is provided with a lower support and a propelling device, the lower support is provided with a reinforcing box with an opening at the upper end, the reinforcing box is filled with compacted soil, and the film bag sand to be detected can be placed above the reinforcing box. The propelling device comprises a pressing plate and a driving assembly for driving the pressing plate to move up and down, and the pressing plate abuts against the middle of the to-be-tested film bag sand. By increasing the pressure and reading the pressure reading of the press, the shear strength of the film bag sand can be calculated. The device has the characteristics of simplicity in operation, convenience and rapidness, and has good economic benefits. 本实用新型提供一种膜袋砂的剪切强度的检测装置，包括可显示当前压力值的压力机，压力机具有下部支座以及推进装置，下部支座上设置有上端敞口的加固箱，加固箱内填充有压实土，加固箱的上方可放置待测膜袋砂，推
