Description

Technical Field

[0001] This application relates to the technical field of airport pavement, and particularly to a method and system for fine control of the thickness of the overlay project for airport pavement. Background Art

[0002] With the construction and operation of airports, China's early civil airports have gradually entered the stage of reconstruction and expansion, and the business volume of reconstructed and expanded airports is relatively large.

[0003] In the reconstruction and expansion of airports, the most important work is the overlay project for airport pavement. Laying an overlay on the existing pavement is restricted by various factors. First, due to the complex and intertwined current pavement, with large settlement, warping, and slab corner height differences, it is difficult to control the uniformity of the overlay; second, some airports have been reconstructed and expanded more than once, with a large number of overlaps between the new and old pavements, making the control of the step difference more cumbersome; third, in the overlay project, it is necessary to consider both the service thickness of the pavement and the slope connection for drainage, and it is difficult to achieve both thickness and slope control; fourth, in the overlay project, economic factors also need to be considered. Since the overlay area is huge, if the overlay thickness is relatively thick, the investment will increase significantly. If the overlay is relatively thin, although the investment is saved, the service life of the pavement is shortened and diseases are likely to occur. Therefore, it is very necessary to determine a reasonable and appropriate overlay thickness, finely control the overlay thickness, and improve the overlay uniformity. Summary of the Invention

Thus, features defined with "first", "second", and "third" may explicitly or implicitly include at least one of such features. In the description of this application, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined. In the embodiments of this application, all directional indications (such as up, down, left, right, front, back...) are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0044] The traditional design method of the pavement overlay in the industry controls the elevation and slope length of the control points and adopts the method of manual Excel calculation and manual proofreading. This method manually counts the elevation of each current point one by one, then inputs them into the Excel table one by one, derives the elevation of adjacent points according to the slope requirements, and then calculates the overlay thickness by back-calculating the current elevation of the points. Finally, the volume of the overlay is calculated using the grid volume method, and all the volumes are added up to obtain the total volume of the overlay. On the one hand, it is difficult to fully disclose problems such as pavement unevenness, local water accumulation, and excessive or insufficient overlay thickness through manual inspection, which is likely to cause serious design quality problems. On the other hand, even for an ordinary airport, since the number of pavement batching points is in the tens of thousands, the traditional method is time-consuming and laborious, with low accuracy and high difficulty in changing the scheme. Therefore, it is very urgent to propose a convenient and fast method for fine control and design of the pavement overlay project.
