Abstract

The invention relates to an automatic roadbed modulus testing device and a testing method. The automatic roadbed modulus testing device comprises a collision apparatus and a signal acquisition apparatus, the collision apparatus comprises a mounting frame, a first driving mechanism is fixedly connected to the mounting frame, an output shaft of the first driving mechanism is connected with a reel through a clutch, the collision apparatus further comprises a lead mechanism, the mounting frame is fixedly connected with a second driving mechanism for driving the lead mechanism to rotate in a horizontal plane, the lead mechanism comprises a support fixedly connected with an output shaft of the second driving mechanism, a lead rod rotationally assembled on the support and a third driving mechanism driving the lead rod to rotate, a lead groove is formed in the lead rod, a lead wheel is arranged at the end of the lead rod, and the rotating axis of the support perpendicularly intersects with therotating axis of the lead rod. The roadbed testing device is simpler to operate, a steel ball is sequentially located right above seven measuring points by rotating the lead rod, and the roadbed modulus testing efficiency and the automation degree are improved.

Description

technical field [0001] The invention belongs to the technical field of roadbed modulus testing, in particular to a roadbed modulus automatic testing device and a testing method. Background technique [0002] Subgrade refers to the belt-shaped structure built according to the location of the route and certain technical requirements as the foundation of the road surface. It is the foundation of railways and highways. The subgrade is a linear structure built with soil or stone. [0003] In terms of materials, roadbeds can be divided into three types: soil roadbeds, stone roadbeds, and earth-rock roadbeds. Subgrade is a structure that directly supports the road surface formed by filling or excavation. The subgrade is connected with bridges and tunnels to form a line together. There are two basic forms of subgrade according to its terrain conditions: embankment and cutting, commonly known as filling and excavation. The function of road subgrade is to pave the pavement structur...
