Water jet cutting device for repairing craters in airport runway

Abstract

The invention relates to a water jet cutting device for repairing craters in an airport runway. The water jet cutting device comprises a cutting system, a sand supply system, a pressurization system and an auxiliary system, wherein the cutting system is provided with a high-pressure water sprayer, the sand supply system is provided with a sand storage tank, the pressurization system is provided with a reciprocating type pressurizer, and the auxiliary system is provided with a water energy accumulator; the two ends of the reciprocating type pressurizer of the pressurization system are connected to one end of the water energy accumulator of the auxiliary system through pipelines, and the other end of the water energy accumulator is connected with the high-pressure water inlet of the high-pressure water sprayer through a pipeline; the sand storage tank of the sand supply system is connected with the sand inlet of the high-pressure water sprayer through a pipeline. The water jet cutting device has the advantages that the cutting speed of the water jet cutting device is superior to that of a conventional mechanical cutting machine; as the water cutting ability is concentrated, the impact on the road surface is small, the cutting quality is superior to that of a mechanical cutting technology, and the locking phenomenon cannot occur; in the cutting process, the depth feeding is not needed, and the cutting straightness does not need to be ensured; as cutting media are water and abrasive materials, no damage phenomenon of cutters during cutting exists, the cost is low, and no dust and noise pollution exist.

Description

technical field [0001] The present invention relates to a mechanical device, specifically a water jet cutting device for repairing bomb craters on airport runways. technical background [0002] In military warfare under modern high-tech conditions, winning air supremacy is one of the important conditions to ensure the victory of the war. According to the history of war, attacking airports and striving to destroy enemy aircraft before they take off are also important means to seize air supremacy. When the airport is partially or slightly damaged, whether the runway crater can be quickly and effectively repaired to improve the ground survivability of the fighter is a very difficult problem at present, and it has been paid more and more attention. [0003] At this stage, concrete cutting machines are widely used in engineering to repair the damaged pavement. The core of the technology is concrete cutting machines, but there are the following problems in practical applications: ...

AI Technical Summary

Problems solved by technology

If the above conditions cannot be met, the straightness of the cutting machine cannot be guaranteed, which will seriously affect the cutting stability of the cutting machine

[0006] 3. The cutting blade is easily damaged; during mechanical cutting, different cutting environments use different types of knives. When the resistance suddenly increases or the straightness of cutting cannot be guaranteed, the blade is easily damaged

[0007] 4. The cutting noise is loud and there is a lot of dust; when cutting with a mechanical cutting machine, there will be a lot of dust, accompanied by harsh sounds, these factors are extremely unfavorable to cutting operators

The setting and hardening process of cement needs to last for several days or even months, so this method has problems such as long time and low early strength.
