Impact toughness detecting device and detecting method for airport runway pavement structure

Abstract

The invention discloses an impact toughness detecting device and an impact toughness detecting method for an airport runway pavement structure, which relate to the technical field of airport runway pavement impact resistance detection. The impact toughness detecting device comprises a bottom plate, wherein a pushing hand for pushing the bottom plate is mounted on one side of the bottom plate, three side plates are mounted on the upper end of the bottom plate equidistantly, and the upper end of the bottom plate is provided with a servo motor at a position close to one side of the side plates. The impact toughness detecting device calculates impact forces to the airport runway pavement under different gravities by utilizing a gravitational potential energy formula can obtain different data for comparison under the conditions of different heights and gravities, adopts a double-row design for testing pavements the adjacent regions simultaneously, makes the operation more labor-saving by combining with the se of electromagnetic chucks, saves the trouble of manual calculation by comparing multiple sets of data and utilizing automatic calculation of the computer, is convenient to move, issuitable for testing multiple regions of the airport runway, saves time and labor, and is precise in detected data values.

Description

technical field [0001] The invention relates to the technical field of impact resistance detection of airport runway surfaces, in particular to an impact resistance toughness detection device and detection method of airport runway surface structures. Background technique [0002] Airport runway refers to the ultra-long strip area used to supply aviation aircraft to take off or land in the airport. Its material can be asphalt or concrete, or flattened grass, soil or gravel ground, or water surface, or even It is laid with planks, shale, polyps, clay, etc. Runways around the world are now mostly land-based. The level of an airport's flight area generally depends on the level of the airport's runway. The performance of the runway and the corresponding facilities determine what level of aircraft can use the airport. Airports are classified according to this capability, called the level of the flight area. [0003] With the increasing use of aircraft, the paving of its airport ...

AI Technical Summary

Problems solved by technology

[0003] With the increasing use of aircraft, the paving of its airport runways is becoming more and more strict. During the construction of the runway, the runway surface needs to be strictly tested before it can start running. At present, the pressure and impact resistance of the runway surface The detection equipment for the force is too heavy and the detection is not convenient enoug
