Abstract

The invention provides a novel roadbed modulus automatic testing device which comprises a collision device; the collision device comprises a mounting frame, a lifting mechanism is arranged on the mounting frame, a collision ball is mounted on the lifting mechanism, a moving mechanism mounted on the mounting frame is arranged below the lifting mechanism, and under the action of the moving mechanism, the lifting mechanism drives the collision ball to move to a test point. According to the technical scheme, the novel roadbed modulus automatic testing device can complete roadbed modulus automatictesting, the structure of the roadbed modulus automatic testing device in the prior art is optimized, and the novel roadbed modulus automatic testing device is firm in structure, good in durability, long in service life, low in manufacturing cost, convenient to use and more practical.

Description

technical field [0001] The invention belongs to the technical field of roadbed modulus testing, in particular to a novel automatic testing device for roadbed modulus. Background technique [0002] Subgrade modulus testing is an important process of road construction quality testing. The method of testing soil subgrade modulus with a falling ball instrument is recorded in the on-site test regulations for highway subgrade pavement. Specifically, each measuring area contains at least seven measuring points, six of which are evenly spaced on a circle centered on another measuring point, and the falling ball is placed in each measuring point area in turn for measurement. During the use, it was found that the operation of moving the falling ball instrument multiple times is inconvenient. At the same time, it is difficult to ensure the accuracy of the falling ball height of each measuring point after manually moving the falling ball instrument many times, and the test efficiency is...
