Description

Technical Field

[0001] This utility model belongs to the field of asphalt pavement testing technology, and in particular relates to an asphalt pavement asphalt layer thickness testing device. Background Technology

[0002] Asphalt is a complex, dark brown mixture composed of hydrocarbons of varying molecular weights and their non-metallic derivatives. Due to its viscosity and waterproof / moisture-proof properties, asphalt is frequently used in road paving. Asphalt pavement consists of three layers: a surface layer, a base layer, and a subbase. The surface layer is the asphalt layer made from asphalt mixtures. The base layer is constructed from concrete and crushed stone, offering high strength and impact resistance. The subbase is made from natural gravel or other crushed stone, ensuring the stability of the surface and base layers. Therefore, asphalt pavement is one of the most widely used high-grade pavements in road construction. The most common quality inspection for highway pavements is the measurement of asphalt thickness.

[0003] The thickness of asphalt pavement is usually measured by drilling a core sample. This method can accurately measure the actual thickness of the asphalt pavement and has the widest range of applications. However, the existing devices for drilling core samples have certain shortcomings: gravel will fly everywhere during drilling, and water will be poured on the drill bit to cool it in order to protect it. The debris mixed with this sewage will also flow everywhere. After the core sample is taken, it is difficult to clean the road surface, which poses a certain safety hazard to vehicles traveling on the road. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an asphalt pavement asphalt layer thickness detection device, and the technical solution adopted is as follows:

[0005] An asphalt pavement asphalt layer thickness detection device includes a drilling machine. A T-shaped bracket is provided on both sides of the base of the drilling machine. A sleeve plate is provided below the drill bit in the drilling machine. A T-shaped clamping block connected to the T-shaped bracket is provided on one side of the sleeve plate. A sponge pad is clamped at the bottom of the sleeve plate. A pressing mechanism for squeezing the sponge pad is provided inside the sleeve plate and above the sponge pad.

[0006] Furthermore, the pressing mechanism includes a pressure plate that contacts the sponge pad, a connecting plate above the pressure plate for passing through the top of the sleeve plate, and a top plate above the connecting plate.

[0007] Furthermore, multiple mounting holes are provided in the connecting plate, and a connecting plate is provided inside the sleeve plate at the position of the mounting hole in the connecting plate. The connecting plate passes through the mounting hole in the connecting plate to prevent the pressing mechanism from falling out of the sleeve plate.

[0008] Furthermore, a spring is provided above the connecting plate to support the top plate. Under the action of the spring, the pressing mechanism can remain in the raised state.

[0009] Furthermore, a circular slot for spring embedding is provided on the upper surface of the connecting plate and the lower surface of the top plate, which can prevent the spring from deflecting and popping out when the pressing mechanism is pressed down.

[0010] Furthermore, after the sponge pad is embedded in the sleeve plate, the lower end of the sponge pad protrudes 2-5cm from the lower surface of the sleeve plate, which can block and absorb the flowing sewage and debris.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This invention uses a sleeve plate of a certain height and a pressing mechanism to block the flying stones during drilling. The protruding sponge pad under the sleeve plate can block and absorb the flowing sewage and debris, confining them within a certain range, which facilitates subsequent cleaning and collection, and makes it more efficient.

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0020] As attached Figure 1-4 As shown.

[0021] An asphalt pavement asphalt layer thickness detection device includes a drilling machine 1. A T-shaped bracket 11 is provided on both sides of the base of the drilling machine 1. A sleeve plate 2 is provided below the drill bit in the drilling machine 1. A T-shaped clamping block 21 connected to the T-shaped bracket 11 is provided on one side of the sleeve plate 2. The sleeve plate 2 is installed by a snap-fit ​​method, which is convenient for disassembly.

[0022] A sponge pad 4 is fitted at the bottom of the sleeve 2. Inside the sleeve 2 and above the sponge pad 4, there is a pressing mechanism for squeezing the sponge pad 4. The pressing mechanism includes a pressure plate 33 that contacts the sponge pad 4. Above the pressure plate 33, there is a connecting plate 3 for passing through the top of the sleeve 2. Above the connecting plate 3, there is a top plate 31. Multiple mounting holes 32 are formed in the connecting plate 3, as shown in the attached figure. Figure 3 As shown, a connecting plate is provided inside the sleeve plate 2 and at the position of the mounting hole 32 in the connecting plate 3.

[0023] A spring 5 is provided above the connecting plate to support the top plate 31. Under the action of the spring 5, the pressing mechanism is in the raised state. After the pressing mechanism is pressed down, the top plate 31, the connecting plate 3, and the pressure plate 33 fall together and squeeze the sponge pad below.

[0024] To prevent the spring 5 from deflecting and popping out when the pressing mechanism is pressed down, a circular slot for embedding the spring 5 is provided on the upper surface of the connecting plate and the lower surface of the top plate 31.

[0025] As attached Figure 3 As shown, after the sponge pad 4 is embedded in the sleeve plate 2, the lower end of the sponge pad 4 protrudes 2-5cm from the lower surface of the sleeve plate 2.

[0026] During use, the sleeve plate and pressing mechanism of a certain height can block the flying stones during drilling, and the protruding sponge pad under the sleeve plate 2 can block and absorb the flowing sewage and debris, confining them within a certain range for easy cleaning and collection later. After core taking is completed, the sleeve plate 2 can be separated from the drilling machine 1. After separation, by pressing the pressing mechanism above the sleeve plate 2, the pressure plate 33 can be moved down to squeeze out the sewage absorbed in the sponge pad 4 for the next use.
