A construction device for pre-embedded temperature sensor on road site

Abstract

The invention discloses a construction device for pre-burying a temperature sensor on a road site, and belongs to the field of road engineering. The construction device comprises a base, a front supporting rod, a rear supporting rod, a jack and a vibration platform are arranged on the base, the vibration platform is provided with a vibrator, a supporting plate is further arranged on the rear supporting rod, a rolling shaft and a conveying belt are arranged on the supporting plate, and vertical clamps for fixing the temperature sensor are arranged on the conveying belt. During construction, the temperature sensor located on the conveying belt can fall to an asphalt road surface through transmission of a series of operations so that temperature field characteristic study of the asphalt road surface can be completed according to the temperature sensor. Compared with a mode of core boring sampling in the prior art, temperature data of the inner layer of the asphalt road surface can be accurately obtained, and therefore the service life of the asphalt road surface is accurately judged according to the actually-obtained temperature data.

Description

technical field [0001] The invention belongs to the field of road engineering, in particular to a construction device for pre-embedding a temperature sensor on the road site. Background technique [0002] Asphalt pavement is widely used in high-grade pavement due to its own comprehensive advantages (comfortable driving, low noise, convenient maintenance, etc.). However, asphalt mixture is a typical temperature-sensitive material. The performance changes that occur under these conditions often become the root of various diseases of asphalt pavement, such as high-temperature rutting, low-temperature cracking, etc., which reduce the performance and driving comfort of the pavement, and seriously shorten the service life of the road. Therefore, it is of great theoretical and practical significance to carry out corresponding research on the temperature field characteristics of asphalt pavement and clarify its performance change law under changing temperature conditions for prolong...

Problems solved by technology

[0005] The temperature detection point of the drill core sampling is inconsistent with the actual temperature state of the measured pavement, and the test depth is limited, only the asphalt surface layer, which cannot fully reflect the temperature state of the pavement structure, resulting in the inability to accurately obtain the actual temperature of the asphalt pavement. Leading to the inability to accurately judge the life of the road
