Cleaning machine for wheel mark on airfield pavement

Abstract

The invention discloses an airport pavement wheelmark scavenging machine, comprising a bracket, wherein a water tank, a disc brush and a fixing wheel are arranged on the bracket; the fore part of the bracket is in rotary connection with the fixing wheel; the rear part of the bracket is in rotary connection with the disc brush, and the rotary power of the disc brush is supplied by a motor; a crank is in threaded connection with the bracket; the lower end of the crank is connected with a universal wheel; the lower part of the water tank is provided with a water tank switch; a water outlet pipe is connected with the water tank switch and positioned in front of the disc brush; and water outlet pores are arranged on the water outlet pipe. Compared with the prior art, the invention has the following advantages that: the machine has no corrosive effect to a pavement, causes no strength reduction or pavement breakage, cannot damage the seam material of the pavement, cannot cause seam grouting material to fall off so that rainwater infiltrates foundations to reduce the strength of the foundations or cause pavement breakage, does no harm to the bodies of constructors, causes no environmental pollution, and has little difficulty in construction, relatively lower requirement on the constructors and relatively lower cost.

Description

technical field [0001] The invention relates to a mechanical device for removing tire marks on cement concrete airport pavement or pavement, in particular to an airport road wheel mark removing machine for cement concrete airport pavement or road wheel marks. Background technique [0002] The airport runway is an important carrier to ensure the safe take-off and landing of aircraft. Due to the frequent take-off and landing of aircraft all year round, there are many aircraft tire footprints in the take-off and landing zones at both ends of the runway. Under normal circumstances, thicker aircraft tire tracks are distributed within the range of 200-300 meters long and 30 meters wide near the centerline at both ends of the runway. Aircraft tire marks will bring the following flight safety hazards: First, the anti-skid performance (friction coefficient and roughness) of the road surface in the take-off and landing zone of the runway decreases, which cannot meet the requirements o...

AI Technical Summary

Problems solved by technology

Aircraft tire marks will bring the following flight safety hazards: First, the anti-skid performance (friction coefficient and roughness) of the road surface in the take-off and landing zone of the runway decreases, which cannot meet the requirements of the specification. According to measurements, the friction coefficient of the road surface in the area with aircraft tire marks is 0.3 -0.5, the minimum is only 0.2, or even lower, which is far from the standard of 0.61, which is a "good" friction coefficient required by the code.

The second is that the wheel tracks of the aircraft will blur the aircraft marking lines on the runway, which will affect the accuracy of the pilot's judgment of the runway when the aircraft takes off and lands.

Third, the long-term existence of aircraft wheel tracks has a certain corrosion effect on the pavement, affecting the strength of the pavement

[0003] Previously, there was a method for removing aircraft wheel tracks, that is, using chemical agents (certain formula). The disadvantages of this method are: first, it is highly corrosive to the pavement, resulting in reduced strength and damage to the pavement

The second is to directly dissolve the joint material of the pavement, causing the joint filling material to fall off, and the rainwater can easily seep into the foundation from the joint, reducing the strength of the foundation and causing damage to the pavement

Third, it is harmful to the health of construction workers

Fourth, the cost is high, and most of the organic agents used are relatively expensive

Fifth, the construction is difficult, and the mixed solution must be formed in strict accordance with the proportion, which requires high construction personnel

Sixth, the chemical method is only suitable for cement concrete pavement, never for asphalt pavement, because asphalt is easy to dissolve

[0004] The disadvantage of the present invention is that it has limited effect on the asphalt pavement, but it is not absolutely impossible to use it, and it can be used to remove the aircraft tire marks on the asphalt pavement if necessary

Because the aircraft tires are black, and the asphalt pavement is basically black, the aircraft tires are difficult to distinguish, and the effect is limited when used
