Roadbed pavement deflection detection device

Abstract

The invention belongs to the technical field of detection devices, and particularly relates to a roadbed pavement deflection detection device. The roadbed pavement deflection detection device comprises a box body, a protection box which is arranged in the box body and is used for protecting the detector, and the detector arranged in the protection box, wherein the interior of the box body is also connected with a protection assembly which is used for protecting the detector; a stretching-out assembly is further arranged in the protection box and used for stretching the detector out of the protection box for detection; and the protection assembly comprises a protection plate connected with the protection box. According to the device, the hanging assembly is arranged so that the device can hang the detector, damage caused by vibration of the detector in the moving process is avoided, in the embodiment, through combination of the protection box, the protection assembly, the stretching-out assembly and the hanging assembly, the detection capacity of the detector is guaranteed, meanwhile, the protection capacity of the detector is greatly improved, and various use scenes can be met.

Description

Technical field [0001] The present invention belongs to the technical field of detection means, and particularly to a road surface detection apparatus Deflection subgrade. Background technique [0002] Deflection generally refers to a road surface or the roadbed surface modification hundred total vertical clearance position value produced wheel load or a predetermined standard vehicle vertical rebound deformation values, in units of 0.01mm, pavement deflection amount, not only reflects the structure of the pavement subgrade overall stiffness and strength, but also exist with the use of the road surface is an intrinsic relationship, usually greater deflection value, plastic deformation of the pavement structure greater, while the fatigue resistance is also poor, bear heavy traffic; the contrary, good fatigue resistance pavement structure, and can withstand heavy traffic. [0003] When the existing roadbed pavement deflection detection device, when the subgrade pavement deflection ...

AI Technical Summary

Problems solved by technology

[0003] When the existing subgrade pavement deflection detection device is used to detect subgrade pavement deflection, the detection device cannot be protected. Due to the complex road conditions of some subgrade road surfaces, it is easy to cause damage to the detection device and affect the normal detection of the device.

[0004] It can be seen from the above that the existing subgrade pavement deflection detection device cannot protect the detection device, which affects the service life of the detection device
