Road surface thickness detection device for highway engineering

Abstract

The invention discloses a road surface thickness detection device for highway engineering, which comprises a supporting frame, a driving motor is connected to the surface of one end of the supporting frame close to the upper end, a first fixing frame is connected to the surface of one end of the supporting frame at the lower end of the driving motor, and a supporting plate is fixedly mounted on the surface of one end of the supporting frame close to the bottom end. According to the road surface thickness detection device for highway engineering, the pavement thickness detection device is stable in structural connection, exquisite in structure and reasonable in design, a user can mount and dismount the pavement thickness detection device by himself / herself without the help of professionals, the whole operation process is simple and easy to operate, and the pavement thickness detection device is very convenient to popularize and use; and through the arrangement of the driving motor structure and the cooperation of the fixing and supporting damping structure, accurate detection of the pavement thickness can be ensured, measurement errors caused by other factors are reduced, and accurate measurement data can be obtained after a core sample is taken out.

Description

technical field [0001] The invention relates to the technical field of road detection device structure, in particular to a road surface thickness detection device for road engineering. Background technique [0002] Asphalt pavement refers to various types of road surfaces formed by mixing asphalt materials into mineral materials, paving and rolling. Flat, dust-free, impermeable, and durable. Therefore, asphalt pavement is the most widely used high-grade pavement in road construction. After the asphalt is laid on the road, it needs to be laid to a certain thickness to achieve the desired effect. During the paving and compaction of hot-mix asphalt pavement, it is necessary to continuously use measuring tools to insert the paving layer to measure the thickness of loose paving and the compaction thickness before cooling, so as to judge whether the thickness of asphalt paving meets the standard. In pavement engineering, each level The thickness of the road surface is closely rel...

[0002] Asphalt pavement refers to various types of road surfaces formed by mixing asphalt materials into mineral materials, paving and rolling. Flat, dust-free, impermeable, and durable. Therefore, asphalt pavement is the most widely used high-grade pavement in road construction. After the asphalt is laid on the road, it needs to be laid to a certain thickness to achieve the desired effect. During the paving and compaction of hot-mix asphalt pavement, it is necessary to continuously use measuring tools to insert the paving layer to measure the thickness of loose paving and the compaction thickness before cooling, so as to judge whether the thickness of asphalt paving meets the standard. In pavement engineering, each level The thickness of the road surface is closely related to the overall strength of the road. Only when the thickness is guaranteed, the strength of each layer of the road surface and the overall strength can be guaranteed. At present, the core drilling method is a commonly used method for detecting the thickness of the road surface. After taking out the core sample on the road surface, the machine directly measures the thickness of the core sample to measure the thickness of the road surface; the existing road surface thickness detection device has certain disadvantages in use, and the installation and disassembly process is very troublesome due to the complicated structure. It is not a small expense to ask professionals to deal with it. At the same time, the vibration of the machine itself and the outside world may cause the measurement results to be inaccurate.
