Description

Laser pit parameter measurement device

Technical Field

The utility model relates to the technical field of airport pavement pit repair, in particular to a laser pit parameter measuring device.

Background

Air force flight and combat require the reliance on air force airports, however, the air force is most fragile at the airport precisely. Air force airports are the most straightforward and cost effective hit targets for opponents, as it is much more efficient to destroy aircraft on the ground than to kill them in the air. Destroying the infrastructure of the guaranteed aircraft essentially destroys its air combat capabilities. Therefore, after the airport is in distress, whether the damaged pavement can be quickly repaired, so that the damaged pavement meets the take-off and landing operation requirements of the airplane, and the damaged pavement becomes an important factor for restricting the generation of air force fight.

After an airport is struck, there may be hundreds of conventional pits (varying in diameter, depth, possibly accompanied by bumps), underground pits (slight surface damage, cavities in the ground), pits (damage not swept to the substrate), and unperforated shots. In order to recover airport guarantee capability as soon as possible, a complete airport rush repair needs to go through the following stages: the method comprises the steps of evaluating the damage degree, determining a minimum take-off and landing zone, removing non-explosive bullets, cleaning a working surface, determining a repair range, cutting and crushing, backfilling scattered matters, constructing a base layer and a surface layer, cleaning a road surface, and arranging emergency lights, signs and aircraft arresting facilities. The repair range is determined, the scattered matter backfilling and the base layer and surface layer construction are several key links for repairing the road surface, the method has very important decision function on the total efficiency of airport rush repair, and the related test in each link, particularly in the process, is required to be as simple and fast as possible on the premise of ensuring the quality.

After an airport pavement, in particular a cement concrete pavement, the pits formed by the damage of the airport pavement are often accompanied by bulges, as shown in fig. 1. The raised pavement is difficult to recover by rolling, tamping and other methods, and the raised part also belongs to the damaged pavement and needs to be repaired. Therefore, how to quickly determine the uplift range of the pit, i.e., the road surface restoration range, is a very important task before the restoration work starts. The determination of the range is too large, which will significantly increase the repair effort, too small, and will not completely repair the damaged road surface, and in principle, the determination of the damaged range is to determine the boundary of the bulge around the pit, i.e. the abrupt boundary of the elevation of the road surface around the pit.

In the process of measuring parameters of a pit, one of the current common testing methods is called a 'visual method' or a 'measuring rod method', the required tools are two support posts and one measuring rod, the principle of the method is shown in fig. 2, the measuring work of the method is generally operated by 3 persons, 2 persons are responsible for moving the support posts, 1 person is responsible for moving the measuring rod, and the measuring rod is responsible for keeping the measuring rod vertically placed on each measuring point. When testing, each upright post is arranged on two sides of the bullet pit along the direction of the central line of the original runway, the posts are required to be placed on the intact road surface, 1 person moves the measuring rod, and moves along the connecting line between the two posts from the obvious raised position, when the horizontal mark of the measuring rod is horizontal with the three points at the top ends of the two posts, the placing point of the measuring rod is the raised starting point of the road surface, and after the starting point is determined, the mark is taken out from the paint spraying process, so that the test of one measuring line is completed. And transversely moving for 1m or 1.5m, repeating the steps until the whole pit is tested, and connecting the starting points of the bulges measured by each measuring line to obtain the pit bulge range. The test method has the advantages of simple and easily available test equipment, but in the test process, not only the measuring rod is required to be moved, but also the support column is required to be transversely moved for many times, the test process is tedious, the time is long, and the visual alignment of people is only relied on, so that the time is wasted, and a large error is possible. From the operator's demand, the test requires 3 people to cooperate, and a minimum of two people are required, but the test speed is slower. In the testing operation process, an operator needs to take out a paint spraying bottle to bend down to spray paint on the bulge part every time the bulge is determined, and the operation is tedious and time-consuming.
