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

Embodiment 1

[0040] Such as Figure 1-5 As shown, a detection method and an evaluation method for real-time online detection of the compaction quality of the pavement-affected area in the basic flight area in this embodiment. The method includes the following steps:

[0041] Step S1: During the rolling construction process of any vertical vibratory roller with stable performance in the project, the acceleration signal in the vertical direction of the vibrating wheel is collected through the acceleration sensor installed on the side of the vibrating wheel;

[0042] Step S2: Process the acceleration signal and calculate the continuous compaction index value E.

[0043] Step S21: automatically fitting the collected acceleration signal into a continuous acceleration change curve through the detection unit installed on the vibratory roller;

[0044] Step S22: use Fourier transform to perform harmonic analysis on the acceleration curve, the formula is as follows:

[0045]

[0046] In the f...

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...
