Reading device for collecting height of water head in penetration test by using laser

The utility model discloses a reading device for acquiring the height of a penetration test water head by using laser, and relates to the technical field of geotechnical penetration tests. The reading device comprises a mounting seat, a variable water head pipe, a variable water floating head and a laser measuring mechanism, the laser measuring mechanism is fixed at the upper end of the mounting seat, the variable water head pipe is vertically fixed on the mounting seat, the variable water floating head is arranged in the variable water head pipe, and the variable water head pipe is vertically fixed on the mounting seat. The water-changing floating head is located in the laser emission direction of the laser measuring mechanism, and the upper side of the water-changing floating head is a reflective surface. According to the utility model, the height of a water head is measured and read by using laser, so that automatic acquisition can be realized, and the tedious process of manually inputting test data into p
