Description

Technical Field

[0001] The present invention relates to the technical field of road detection, and in particular to a road nondestructive detection method. Background Art

[0002] After the road construction, one of the tests is the road thickness test. The purpose is to better control the construction of different layers to meet the design strength requirements. It is necessary to accurately measure the thickness of different construction layers to ensure that the project quality meets the expected construction requirements. The traditional method is mainly the core drilling method after construction. Although this method can achieve accurate measurement standards, it is necessary to destroy the pavement structure in the actual operation process, and it is a random inspection after construction. It is impossible to control the construction quality in real time and guide the construction plan. For this reason, the latest technology MIT Scan T3 pulse induction non-destructive testing method was born. When paving the road, a metal plate will be set between the subbase, base, middle surface layer, and surface layer. The electromagnetic pulse in the MITSCAN T3 pavement thickness gauge is used to send a pulse signal to the pavement. The pulse signal bounces back through the metal plate, so that the sensor in the MIT SCAN T3 pavement thickness gauge senses the pulse signal, thereby displaying the thickness of each different layer on the panel of the MIT SCAN T3 pavement thickness gauge. However, it is inconvenient to use the MIT SCAN T3 pavement thickness gauge to detect the pavement.

[0003] Therefore, the present application proposes a road nondestructive testing method. Summary of the invention

[0004] The purpose of the present invention is to solve the disadvantage that the existing MIT SCAN T3 pavement thickness gauge is inconvenient to use, and to propose a road non-destructive testing method.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0011] Preferably, the second rod body is provided with a through hole, the through hole is slidably connected to a cross bar, one end of the cross bar is fixedly connected to a connecting rod, the diameter of the connecting rod is smaller than the cross bar, a cylinder is fixedly connected in the slide groove, the cylinder is a hollow structure, a second elastic member is arranged in the cylinder, the other end of the cross bar extends into the cylinder, a blocking ring is fixedly connected to the outside of the second rod body, a sealing ring is fixedly connected to the blocking ring, and the blocking ring and the sealing ring are both sleeved on the outer wall of the connecting rod.

[0012] Preferably, the second rod body is fixedly connected to a connecting plate, the electronic screen is arranged on the connecting plate, and the base is also fixedly connected to two blocks, the blocks have curved surfaces, and the blocks are made of elastic rubber material.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The present invention enables the second rod to rotate accordingly, so that when a person pushes the base to detect the road thickness, the second rod can be pushed at a suitable angle, which is convenient for use. The two blocks on the base are set to prevent the person's hands from slipping off the second rod, so that the second rod touches the blocks, thereby preventing the electronic screen from falling and being damaged.

[0015] 2. The present invention squeezes the connecting rod to move it toward the second elastic member until the slide groove is connected to the outside through the through hole. After that, the position of the first rod body in the slide groove can be adjusted, thereby adjusting the height of the second rod body, which is convenient for personnel to use.

[0016] 3. When the base of the present invention moves on the road, the brush bundle can block large hard objects from entering under the base, thereby preventing the bottom of the base from being hit by hard objects, which is helpful for people to use. At the same time, the brush bundle is subjected to the reaction force of the road, thereby driving the slider to squeeze the first elastic member. Under the elastic force of the first elastic member and the reaction force of the road on the brush bundle, the brush bundle continuously swings back and forth. Combined with the inclined setting of multiple brush bundles, the hard objects blocked by the brush bundles can be gradually moved to both sides of the base until they are completely free from the obstruction of the brush bundles, which is helpful for the movement of the base and further helpful for people to use.
