Description
Technical Field
The invention relates to the technical field of intelligent construction, in particular to a highway foundation continuous compaction monitoring and management system.
Background
The foundation treatment is a crucial part in the engineering construction process. The roadbed is used as a basic structure of highway engineering, and the construction quality of the roadbed engineering directly influences the quality of the highway engineering, the service life, and the safety of the construction period and the operation period. The highway engineering construction generally has the characteristics of long construction line, complex engineering environment, compact construction period, high working strength, high quality requirement and the like. In actual engineering, uneven settlement of a roadbed, roadbed sliding, slope collapse, roadbed structure damage related to the slope collapse and the like caused by improper roadbed construction often influence the normal traffic of a highway. The method for guaranteeing the roadbed construction quality through a new technology, a new process and a new material is an important subject in the technical field of highway construction.
In the existing roadbed construction technical specification, the emphasis is that the compaction quality is detected in a spot inspection mode mainly by controlling the rolling process. However, the conventional high-grade highway construction mainly depends on supervision and constructors to manually control the rolling process of the road roller, and due to the interference of human factors and relatively extensive management, problems of pressure leakage, under pressure, over pressure and the like are often caused, and the construction quality is difficult to ensure. Meanwhile, the traditional compaction quality detection is mainly carried out by a field sampling test, and has the phenomena of undervoltage, pressure leakage and overvoltage, belongs to point control and after-the-fact control, and is difficult to realize process control and comprehensive control. Based on the defects, the method adopts a continuous compaction control technology to comprehensively monitor and detect the compaction quality of the whole rolling surface in real time in the whole process, and is a new way for improving the roadbed construction quality.
The continuous compaction control technology is characterized in that a detection evaluation and feedback control system is established by continuously measuring vertical vibration response signals of a vibration wheel of the vibratory roller according to the interaction dynamic action principle of a soil body and the vibratory roller in the compaction process of a filling body, so that the real-time dynamic monitoring and control of the compaction quality of the whole compaction surface are realized. Currently, three important branches are mainly developed: a harmonic ratio CMV method in Sweden; (vii) vibrational modulus method of germany; and thirdly, a dynamic vibration compaction value VCV method independently developed in China. The principle and the limitation of the harmonic ratio CMV method are as follows:
The harmonic ratio CMV method is a signal analysis method which is used for evaluating the compaction degree by adopting the distortion degree of a dynamic (vibration) response signal of a vibration wheel of a road roller. The method processes the response signal of the vibratory roller from the perspective of signal form processing, and the index is a dimensionless relative value.
In the formula, A2ΩThe second harmonic amplitude of the acceleration of the vibrating wheel; a. theΩThe first harmonic amplitude of the acceleration of the vibrating wheel; c is a formula constant coefficient.
The CMV is a dimensionless ratio whose magnitude is not only related to the behavior of the filling but also limited by the vibration parameters of the road press. The engineering practice and related research at home and abroad show that: under the condition of normally rolling fine granules, the CMV has better relevance with the conventional detection index of the compaction degree, and for coarse-grained hard fillers such as rockfill and the like, the relevance of the CMV and the conventional detection index of the compaction degree is very poor, and the problems still exist when the index is adopted for carrying out compaction quality control and management.
The principle and limitation of the vibration modulus are as follows: the method simulates the interaction between the road roller and the filling body by adopting 'mass-spring-damping', establishes a dynamic equation of a vibration wheel, and solves the stiffness coefficient K in the vibration equation according to the related parameters of the road roller and the related parameters of the soil body B。
Then, a calculation model of the relationship between the load on the round roller and the impression area of the round roller on an elastic half space in contact mechanics is utilized to obtain a rigidity coefficient KBThe relation with the elastic modulus, but when the quality inspection is carried out, the two indexes still need to be related to the conventional indexes to establish the corresponding relation between the two indexes. The limitations of this approach are:
1) the rigidity coefficient and modulus index are determined by support with more parameters, except that the acceleration is directly measured, the speed and displacement are obtained according to the acceleration integral, and other mechanical performance parameters and the like are determined in advance, so that the method is difficult to be applied to a common vibratory roller and can be realized only by equipping a special vibratory roller with known performance parameters;
2) because parameters needed for calculating the index are mostly determined in advance, the index can be realized by a special matched vibratory roller.
The kinetic methods and limitations are: the basic dynamic principle of continuous compaction control is that the vibration rolling process of the filling body is regarded as a dynamic test process (vibration compaction test), and a vibratory roller is dynamic loading equipment. During rolling, the vibrating wheel is subjected to both the exciting force from the machine itself and the resistance (counterforce) of the filling body, and the combined action of the exciting force and the counterforce causes the vibrating response of the vibrating wheel. According to the dynamics and the system identification principle, indexes (such as a vibration compaction value VCV) related to the structural resistance of the filling body can be obtained through real-time measurement and processing of the dynamic response of the vibration wheel, and therefore corresponding compaction quality control is carried out. The limitations of this approach are:
1) In many cases, a verification comparison test is required to be carried out, the relation between the standard index and the standard index is established, and the property of a test road section is required to be the same as that of a subsequent rolling section;
2) the method is suitable for large-area plane compaction detection, and is difficult to be adopted for narrow and small filling sections around buildings or ditches.

The acquisition recorder mainly has the tasks of converting analog signals conditioned by the secondary instrument into digital signals for storage and display, and communicating data with an upper computer. The frequency band of the road roller in operation is generally 20-160 Hz, so the highest sampling frequency is 100kHz, and the sampling precision is enough. The roadbed compaction process is a process of applying vibration load to the compressed filler by the vibratory roller, and is represented as forced vibration. The vibration exciting frequency of a general vibration road roller is 28-45 Hz. For the roadbed, the frequency is 28-32 Hz mostly and 30Hz mostly. Therefore, the dynamic response of the roadbed structure will not generate too high frequency vibration, so the low-pass filtering should be selected to allow the low-frequency component to pass through and filter out the high-frequency signal.
The frequency spectrum structure component of the dynamic response signal of the vibration wheel is generally within the working frequency range of 2-3 times. Therefore, it is appropriate to select an operating frequency with a filtering cutoff frequency of 4 times, which can not only ensure the correctness of the analyzed signal, but also filter out the interference of other noises. The cut-off frequency here is the highest frequency f in the analysis signal mTherefore, there are

After the rolling vehicle finishes working, the system gives a rolling effect evaluation report of the whole area, and the rolling construction quality is judged in an auxiliary mode. The entire visualization system gives a deployment view as shown in fig. 4.
