A road bridge concrete detection device

Abstract

The invention discloses a road bridge concrete detection device, which comprises a front continuous camera, a road detection camera, a telescopic arm, a wireless receiver, a rear continuous camera, a rear driving wheel, a road condition feedback detection device, a main control chassis, and a front driving wheel , the present invention has the effect: because shock absorbers are installed on the front drive wheel and the rear drive wheel, the main control chassis can maintain relative balance when the road surface or bridge surface is bumpy, so when the equipment travels to a bumpy or damaged road section , the undulating force generated by the front drive wheel and the rear drive wheel cooperates with the front road condition detection bracket and the rear road condition detection bracket. The ultrasonic rebound instrument works to detect the concrete quality of the road surface or the bumpy road section of the bridge deck, and uses a continuous camera to shoot and receive the cross bar The degree of undulation can be used to judge the damage degree of concrete on bumpy sections of road or bridge deck, thereby reducing the time for concrete quality inspection of roads or bridges.

Description

technical field [0001] The invention relates to the field of concrete detection equipment, in particular to a road and bridge concrete detection device. Background technique [0002] In today's construction projects, concrete is widely used. No matter it is road structure or bridge and tunnel construction, it is inseparable from concrete. The quality of concrete not only has a great impact on the safety of building structures, but also has a great impact on the cost of construction projects. Therefore, concrete quality inspection is one of the important links in the whole inspection work. At present, most of the roads and bridges in China adopt cast-in-place reinforced concrete structures. During the long-term use of roads and bridges, the structure will inevitably be deformed, resulting in uneven road or bridge decks. In order to ensure the safety of roads and bridges, people need to regularly overhaul roads and bridges to judge whether the quality of concrete can meet the ...

[0002] In today's construction projects, concrete is widely used. No matter it is road structure or bridge and tunnel construction, it is inseparable from concrete. The quality of concrete not only has a great impact on the safety of building structures, but also has a great impact on the cost of construction projects. Therefore, concrete quality inspection is one of the important links in the whole inspection work. At present, most of the roads and bridges in China adopt cast-in-place reinforced concrete structures. During the long-term use of roads and bridges, the structure will inevitably be deformed, resulting in uneven road or bridge decks. In order to ensure the safety of roads and bridges, people need to regularly overhaul roads and bridges to judge whether the quality of concrete can meet the quality standards for continued use. Nowadays, non-destructive methods are usually used to test concrete, which can avoid damage to the concrete. The structure causes local damage. Non-destructive methods are commonly used rebound method and ultrasonic rebound comprehensive method. Compared with the single rebound method, the ultrasonic rebound comprehensive method can reduce the influence of age and moisture content on concrete strength. , to make up for the shortcomings and improve the test accuracy, so the utilization rate of the ultrasonic rebound comprehensive method is relatively high. When the ultrasonic rebound comprehensive method is used to detect the concrete quality of roads or bridges, it is necessary to employ multiple workers to scan the road or bridge section by section. In addition to the data collation and analysis in the later period, it takes a lot of time, manpower and material resources to obtain accurate detection data, which greatly reduces the efficiency of concrete quality detection. Therefore, it is necessary to develop a new type of road bridge concrete detection device to solve the problem of ultrasonic echo When testing the concrete quality of roads or bridges using the comprehensive elastic method, it is necessary to use multiple workers to scan the roads or bridges section by section, and in addition to the later data sorting and analysis, it takes a lot of time, manpower and material resources to obtain accurate testing data. The problem of greatly reducing the efficiency of concrete quality inspection
