Description

Technical Field

[0001] The present invention relates to the technical field of road construction, and in particular to an intelligent real-time measuring device for the rolling effect at a roadbed widening joint and a use method thereof. Background Art

[0002] In pavement engineering, the thickness of each structural layer is closely related to the overall strength of the road. The variation of paving compaction thickness has a great influence on the thickness of each structural layer and the strength of the pavement structure. It also has a certain impact on the generation of rutting, early damage to the pavement, the service life of the road and the flatness. Under the condition of total quantity control, if the measured compaction thickness deviates greatly from the design value of the loose paving thickness, there may be defects or shoddy work during the construction process, which need to be discovered and stopped in time.

[0003] Traditional compaction quality control is to test the compaction degree of the roadbed and pavement through manual core sampling after the rolling construction is completed. When in use, there are problems such as destructiveness to the pavement and low detection efficiency. In addition, the same area may be repeatedly tested during the dirty detection process, which is time-consuming and labor-intensive. If multiple detection and multi-layer measurement methods are used on the same equipment, the number of repeated detections can be reduced as much as possible, which is efficient and does not consume so much time and manpower. Therefore, the present application provides an intelligent real-time measurement device and a method for using the rolling effect at the roadbed widening connection to meet the needs.

[0015] A method for using an intelligent real-time measuring device for rolling effect at a roadbed widening joint comprises the following steps:

[0016] Step 1: First, the road condition scanner can be used to quickly transmit the data model of the road ahead to the construction personnel, and the image analysis of the local road surface can be collected in advance. Then, during the roller process, the built-in sensor and compaction acquisition device inside the front vibration steel wheel measurement component can transmit the compaction data to the construction personnel in real time;

[0017] Step 2: Install a real-time compaction degree collection device on the vibrating steel wheel of the roller, and then use the built-in sensor to collect and analyze the compaction data of the roller and the feedback force waveform of the compacted material, and transmit it to the system cloud center for comparison with the corresponding test data model to determine whether the compaction degree of the current compacted material is qualified;

Non-destructive, accurate and rapid detection is achieved throughout the process, and compaction parameters are fed back in real time to provide the operator with real compaction information and guidance, thereby improving the compaction quality. After the roller is installed with the intelligent compaction system, the driver can observe the rolling situation of the working surface in real time through the navigation tablet installed in the cab, so that the operation has visibility and reduces the leakage or over-pressure caused by the driver's lack of experience. The compaction system can reasonably control the roadbed width, compaction thickness and number of rolling in the roadbed compaction range. According to the compaction status diagram, the weak rolling area can be quickly located and the position can be determined to ensure the scientificity and reliability of the detection, improve the monitoring efficiency, and effectively avoid the misjudgment caused by lack of experience during human operation.

[0022] By setting up ultrasonic scanner components and surface settlement displacement monitoring components, multiple and multi-layer measurements and inspections of the compacted road surface can be provided. The use of ultrasonic scanning of the road surface can better detect the condition of the compacted road surface. At the same time, real-time modeling diagrams are generated to facilitate subsequent staff to compare and view. If there are still deficiencies, the modeling diagrams and data can be used in advance to adopt corresponding remedial measures. The surface settlement displacement monitoring component is placed on the road surface, and is attached to the foundation surface through anchor plates at both ends to accurately sense the slight tilt changes of the measuring unit caused by foundation settlement. The wireless data acquisition terminal adopts CAN field bus communication technology to automatically collect the inclination measurement signals of each settlement measurement unit connected to the bus in real time, automatically calculate each measured settlement, and regularly transmit the wireless remote transmission to the cloud through the GPRS / 4G wireless communication module to conduct a third measurement and inspection.

Non-destructive, accurate and rapid detection is achieved throughout the process, and compaction parameters are fed back in real time to provide the operator with real compaction information and guidance, thereby improving the compaction quality.
