Description

Technical Field

[0001] The utility model relates to the field of road construction, in particular to a device for calculating the rolling quality of a vibratory roller. Background Art

[0002] After searching Chinese patents, the publication number is: CN218405356U, a roadbed compaction detection device, including a roadbed compaction detection frame, a mobile base is provided below the roadbed compaction detection frame, a positioning ring is provided in the middle position inside the mobile base, a soil sampling detection tube is provided inside the positioning ring, and a driving mechanism is provided above the roadbed compaction detection frame. Positioning brackets are provided on both sides of the mobile base in the utility model, and the positioning brackets are adjusted by adjusting the screw rod. When the adjusting screw rod is rotated clockwise, the positioning bracket is extended downward and penetrated into the ground, and at the same time, the supporting spring is contracted to ensure the stability of the positioning bracket adjustment, so that the universal self-locking wheel is separated from the ground, and the sampling position is positioned. When the adjusting screw rod is rotated counterclockwise, it is used to contract the positioning bracket so that the universal self-locking wheel contacts the ground, so as to facilitate the movement of the roadbed compaction detection frame and facilitate carrying.

[0003] The compaction degree of roadbed is a quality control indicator of earth filling engineering. When testing the compaction degree of roadbed, the ring knife method, sand filling method and nuclear density meter method are generally used to test the compaction degree. These detection methods have disadvantages. The ring knife method is limited by the soil quality. When the ring knife is driven into the soil, the stress generated makes the soil loose. The stress generated when the wall is thick is large, so the dry density is reduced. The sand filling method is more complicated to operate, and the density and cone weight of standard sand must be measured frequently. The nuclear density meter method can only be used after comparison and calibration with the sand filling method, which is more troublesome. These detection methods require a lot of manpower and material resources during detection, and cannot continuously, real-time and accurately reflect the true quality of the compaction of the roadbed section. The point-to-surface detection error is large, and it is not easy to clean the smart terminal tablet. Generally, when the smart terminal tablet is in use, dust will adhere to the surface, affecting its use, and it needs to be cleaned. When cleaning, it is generally wiped with a rag, which is more troublesome to use and has low practicality. In order to solve the above problems, we propose a device for calculating the rolling quality of a vibratory roller. Utility Model Content
