Water jet cutting device and rapid repair method for airport runway crater based on water jet cutting device

Abstract

The invention relates to a water jet cutting device and a method for quickly repairing an airport runway crater based on the water jet cutting device. First, a portable water jet cutting device is used to quickly repair the loose area of ​​the crater, so that its cutting shape is as square as possible, and then it is trimmed. The crater was quickly grouted, the concrete modules were filled, and finally the adjustment modules were fixed to make it level, and the repair of the runway was completed. The advantages of the present invention are: the cutting and trimming speed of the water jet cutting device is better than that of a conventional mechanical cutting machine, because the water cutting ability is concentrated, the influence area on the road surface is small, the cutting quality is also better than the mechanical cutting technology, and there will be no jamming phenomenon, There is no need for deep feed during the cutting process, and it is not necessary to ensure the straightness of cutting. Since the cutting medium is water and abrasive (sand), there is no tool damage during cutting, the cost is low, and there is no dust and noise pollution; the invention repairs the crater Methods By adopting the rapid filling method of modules, the shortcomings of insufficient early strength and long hydration reaction time of grouting cement were overcome, and the repairing time was greatly shortened.

Description

technical field [0001] The invention relates to the repair of the bomb crater of the airport runway, in particular to a method for quickly repairing the bomb crater of the airport runway based on a water jet cutting device. 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 ...

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.
