Handheld type roadbed bevel compactness measuring instrument
The invention discloses a handheld type roadbed bevel compactness measuring instrument. The measuring instrument comprises a vertical rod; an electromagnet is arranged on the upper portion of the vertical rod, and a buried probe is arranged at the lower end of the vertical rod; and a force sensor and an acceleration sensor are arranged between the buried probe and the vertical rod, and the position, between the electromagnet and the force sensor, of the vertical rod is sleeved with a heavy punch and a buffer spring. The measuring instrument has the beneficial effects that firstly, in the construction process, the bevel compactness can be reasonably measured, a certain precision requirement is achieved, technical parameter control can be conveniently carried out, and a roadbed structure is safer and more reliable; and secondly, carrying is convenient, operation is easy and rapid, a measuring result can be displayed immediately, survey classification can be carried out on a roadbed bevel side slope of an existing road segment, and serves as the basis of quality control in the construction process, and the reliable basis is provided for relevant daily maintenance and future protection measures of a roadbed. The measuring instrument well solves the problem that an existing method and an existing instrument cannot effectively measure the compactness of the roadbed bevel side slope, and consequently, stability cannot be judged.
