Heavy launch-Smart Rolling Monitoring System (SSFS-ICCC)

 

The Smart Rolling Monitoring System (SSFS-ICCC) is mainly for earth and rock filling projects in various types of infrastructure construction. It can remotely monitor the rolling trajectory, rolling rate, and number of rolling parameters of rolling equipment in real time. The proposed compaction value of CEV (Compaction E Value) reflects the phenomenon of "spring soil", local over-hardness (super-large particle size filler) or over-softness in real time, and reflects the compaction uniformity of the entire working surface. Combined with the falling ball detection equipment, the CEV index can be unified with the actual detection parameters. The system can also monitor the truck and loader through the mobile phone APP. After the rolling is completed, the rolling quality can be quickly detected by the falling ball detection equipment to achieve integrated management of rolling and detection, effectively prevent overpressure and underpressure, and achieve optimal rolling in the construction section. It has scientific judgment and intelligence. High, efficient and friendly man-machine interaction.

 

I. System Principle

 

The vibration compaction tool is used as the loading device. Based on the interaction between the compaction tool and the subgrade, the compaction status of the subgrade is analyzed and evaluated by the reaction force (resistance) of the subgrade structure, thereby achieving continuous compaction quality during the compaction control.

 

Purpose of R & D

 

1. Guide the subgrade rolling work to avoid over or under pressure on the subgrade

 

2. Efficient construction to improve the uniformity of subgrade compaction

 

3.Integrate continuous compaction data and compaction results, easy to query and analyze, test results

 

4. Improve compaction, uniformity and stability;

 

5.Combined with advanced detection technology;

 

6.Statistical data, generate reports, evaluate construction progress and effects, and grasp the progress of subgrade compaction

 

Three, system function

 

Remote online monitoring of roller compaction

 

① Real-time drawing of rolling track and automatic calculation of rolling times;

 

② Automatically calculate the vibration frequency and rolling rate;

 

③ Automatically draw the heat map of the rolling track;

 

④ The area proportion of each rolling times is calculated automatically.

 

2. Automatically calculate and draw cloud map based on CEV compaction value

 

的 The characteristics of using CEV compared to other methods:

 

① CEV itself is an elastic modulus index, and theoretically has a good linear relationship with the elastic modulus of the material;

 

② CEV can reflect the rolling force, quality, and width of rollers, and has wider applicability;

 

③ Poisson's ratio of the material is also reflected in the falling ball detection, and the technical matching is better.

 

3, using the falling ball for compaction detection

 

According to the special falling ball rebound modulus tester + Chihiro positioning module, the detection data is accurately positioned to the construction area, which accurately reflects the true compaction of the construction area.

 

4.Mobile APP monitors the track of the material carrier

 

Monitor the trajectory and unloading movement of the material truck, automatically calculate the number of times of transportation to prevent the phenomenon of cutting corners.

 

Technical advantages

 

1. Apply advanced falling ball detection technology innovation to rolling calibration to make the result more accurate;

 

2. All-round quality monitoring of compaction degree, compaction uniformity and compaction stability during compaction, and fast positioning of weak areas during compaction;

 

3.Compact efficiency is high. Compared with the traditional pumping point detection, continuous compaction detection achieves full coverage, guides conventional manual inspections, accurately locates weak areas, and accurately locks under-pressure areas after stopping rolling to compensate pressure

 

4. High-precision GPS positioning to achieve accurate recording of rolling track.
