Detection system and method for detecting compaction quality of road surface influence area of basic flight area

Abstract

The invention discloses a detection system and method for real-time online detection of compaction quality of a road surface influence area of a basic flight area, and particularly relates to a real-time detection and acceptance method for the compaction quality of an airport flight area pavement influence area. According to the method, based on stress wave propagation in the compaction process, the frequency spectrum characteristics of reflected stress waves are obtained by analyzing the vibration characteristics of a vibrating wheel of the vertical vibratory roller, a continuous compaction index E is provided, and an evaluation system and an acceptance check method for the compaction quality are established. The method can quickly, accurately and efficiently detect the compaction degreeand uniformity of the compaction layer in a lossless manner, establish an acceptance standard and effectively guide compaction construction management.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to an online real-time detection system and method for detecting the compaction quality of a pavement-affected area in a basic flight area. Background technique [0002] It is the most important process in the construction of the affected area of ​​the pavement in the airport flight area when the pressure is implemented. At present, the compaction quality indicators of civil airports are mainly compaction degree, roadbed response modulus (k 0 ), California Bearing Ratio (CBR) indicators. The management and control of the compaction quality can be realized through these indexes in the field construction. The current compaction quality detection mainly has the following problems: [0003] (1) The compaction quality detection method obtains detection indicators through sampling, and there is a problem of whether the sampling point is representative, which cannot ref...

AI Technical Summary

Problems solved by technology

[0003] (1) The compaction quality detection method obtains detection indicators through sampling, and there is a problem of whether the sampling point is representative, which cannot reflect the overall construction quality, and after quality problems are found, it cannot accurately reflect the area and distribution of the area where the compaction quality does not meet the standard;

[0004] (2) The construction of the pavement affected area in the airport flight area has high requirements for post-construction settlement, and the post-construction differential settlement runway along the longitudinal direction requires 1.0-1.5‰, and has high requirements for the uniformity of site compaction. Conventional detection methods cannot reflect site pressure. Whether the actual quality is evenly up to the standard;

[0005] (3) The quality inspection method belongs to post-event control, and the efficiency is not high. The next step of construction can only be carried out after the inspection is completed. After the problem is found, it needs to be reworked, which will increase the labor cost and affect the construction progress;

[0006] At the same time, there is still a disconnect between the compaction quality inspection and the construction process. The airport compaction construction still lacks a relatively complete construction inspection and management system to manage and monitor the compaction quality and ensure the overall compaction quality of the site.
