Description
Technical Field
The utility model relates to a bituminous paving sampling test equipment technical field especially relates to a can prevent bituminous paving that pitch splashes and detect and use sampler.
Background
Asphalt road is a popular name, known as asphalt concrete pavement, and is a road pavement widely used, also known as an asphalt road. Most of the highways in China are paved by asphalt roads. The materials required for paving asphalt road include graded aggregate, broken stone grading, asphalt cement, aggregate, stone powder, etc. The required tools comprise a road grader, an excavator, a vibration roller, a truck, a road scraper, an asphalt spreader, a paving machine, a pressure oil splashing vehicle and the like. The quality of the asphalt road is detected after the asphalt road is repaired, a sampler is usually used for sampling during detection, but asphalt gas is generated due to severe friction between a blade and the road surface during sampling of the existing sampler, which is not beneficial to the health of human bodies, and moreover, solid particles are splashed from the road surface cut by the blade during sampling, which easily injures people and has potential safety hazards; moreover, the whole sampler can vibrate greatly during sampling, which affects the sampling accuracy.
In order to solve the technical problems, a novel sampler for pavement quality detection is disclosed in the chinese utility model patent No. ZL 201721714118.6, which comprises a motor, a cylindrical frame, a handle, a sample storage box, a micro air pump, a gas absorption box, a corrugated pipe, a spring and an annular bottom plate; the method is characterized in that: the motor is arranged on the upper end face of the cylindrical frame, a rotating shaft is arranged at the bottom of the motor and penetrates through the cylindrical frame, a sample storage box is connected to the bottom of the rotating shaft, the sample storage box is of a hollow cylinder structure, cutter teeth are uniformly arranged on the edge of the bottom of the sample storage box in the circumferential direction, handles are arranged on the left side and the right side of the upper portion of the cylindrical frame, an exhaust port is formed in the middle of the left end face of the cylindrical frame, a miniature air pump is fixedly arranged in the middle of the cylindrical frame and aligned with the exhaust port, an air guide pipe is arranged at the bottom of the miniature air pump, a gas absorption box is connected to the bottom of the air guide pipe, a corrugated pipe is arranged at the bottom of the cylindrical frame, a spring is longitudinally arranged in the corrugated pipe, and the cylindrical frame is, and an air outlet is formed in the left side wall of the middle upper part of the sample storage box. In the use, miniature aspiration pump and gas absorption box mutually support and can produce the gaseous absorption of pitch with the violent friction in blade and road surface when taking a sample, and pitch gas is taken in by miniature aspiration pump and is passed through the air duct and get into gas absorption box to absorb by the sodium hydroxide solution in the gas absorption box, be favorable to human health. The corrugated pipe, the spring and the annular bottom plate are mutually matched, so that the phenomenon that the blades splash out small solid particles to hurt people when cutting a road surface can be avoided.
However, in the actual use process of the above prior art, the particles of crushed asphalt cannot be effectively prevented from splashing all around, and the small particles of splashed asphalt solids cannot be prevented from diffusing all around when the cutter teeth cut the asphalt pavement, because the annular bottom plate at the bottom is in rigid contact with the asphalt pavement, when the asphalt pavement is uneven, a certain gap exists between the annular bottom plate and the asphalt pavement, and when the asphalt pavement is violently cut, the solid particles of asphalt will splash all around from the gap between the annular bottom plate and the asphalt pavement. Therefore, the phenomenon that the small solid particles splashed when the blade cuts the pavement can not be avoided to hurt people.
