Intelligent compaction (IC), also known as continuous compaction control (CCC), is an evolving and innovative technology. Using this technology, equipment equipped with integrated measurement and navigation systems delivers the best compaction performance. As a leading manufacturer of compaction equipment, the Wirtgen Group's Hummer brand provides users with a complete intelligent compaction and data management system through this compact navigation system.
At the 2016 Bauma show in China, the Hummer brand presented the latest generation of compaction navigation systems to help users improve compaction quality and reduce compaction. The Hummer compaction navigation system can easily and flexibly improve the compaction process in the earthwork implementation, leaving a deep impression on the user.
Modern intelligent twin drum rollers and single drum rollers not only perform compaction operations, but also have many other uses, such as accurately determining the time and area for further compaction, which is the HCQ Hummer compaction navigation system. Advantages are located.
The system significantly optimizes the compaction process in terms of both technical and economic benefits and offers a wide range of construction solutions. The HCQ system can be integrated into any single drum roller of the Hummer 3000 series and on all other rollers equipped with Tier 3 engines.
Generate real-time compacted maps
During the compaction process, the Hummer Compaction Navigation System records different materials and equipment data. At the same time, a DGNSS receiver (GNSS: Global Navigation Satellite Positioning System, such as GPS) will determine the current position of the roller. The Hummer compaction navigation system links the construction process to the location information, creating a real-time compacted image that is displayed on the tablet in the cab.
The display image is clear and easy to identify, allowing the operator to understand the compaction process based on the color image, and the location map or geographic coordinate line can be clearly displayed for better positioning. At the same time, the system can also display two images side by side (such as the increase in compaction and compaction passes), as well as other information such as vibration frequency or amplitude.
Better compaction quality and more time saving
Hummer compaction navigation system can effectively avoid unnecessary repeated compaction and make construction more efficient. In addition, the compaction effect under the system is more uniform and the quality is higher, which can effectively prevent the lack of ground stiffness caused by insufficient compaction in some areas.
Successfully introduced to China
The Bijie Highway Administration is the first user in China to use the Hummer compaction navigation system. During the course of their use, they quickly discovered that this advanced technology can achieve higher construction quality in a shorter period of time.
The first construction project carried out by the customer using the 3625 HT earthmoving roller equipped with the Hummer compaction navigation system was carried out in the cold recycling construction of Bijie City, Yungui Plateau. This project is to repair the Bijie-Nayong X 307 highway and the 49-km long, average 6.5 m wide S 102 expressway Weining Zhao passage section. This mountainous section has a large amount of traffic, complex terrain and poor geological conditions, and must be compacted.
During the construction process, the Hummer compaction navigation system can display the compaction process in real time, allowing the operator to accurately observe where the ground has not been fully compacted. The operator stated that with the Hummer compaction navigation system, it is always possible to see which areas need further compaction. Whether it is compacted in a scenic spot or elsewhere, it can form a uniform road surface.
The success of this project fully demonstrates the great advantages of the Hummer compaction navigation system. The project manager of the Bijie Highway Administration stated that the use of the Hummer compaction navigation system not only significantly improved the compaction efficiency. It can also effectively avoid insufficient compaction and over-compaction.
The compaction analysis also proves that the Hummer single drum roller equipped with the Hummer compaction navigation system can form a high quality compacted road surface. At the same time, construction time and fuel are greatly saved due to fewer compaction passes. The person in charge of the project said that with the Hummer single-roller roller equipped with HCQ compaction navigation system, the compaction degree was significantly improved, and the road bearing capacity and service life were increased by 10 - 15%. Compared with the traditional compaction process, the compaction advantage of the Hummer compaction navigation system is significant.
Rugged parts
The construction project of the Yunnan-Guizhou Plateau uses a Hummer single drum roller equipped with a cab. The rugged, high-powered tablet is military-standard and stable at temperatures from -40°C to +70°C. The enclosed, all-metal enclosure (IP65) ensures that the computer is effectively waterproof and vibration-proof, so it can also be installed On the model of the open bridge. The magnetic base allows the receiver to be easily and quickly mounted on the cab roof. At the same time, the DGNSS receiver and tablet can be changed freely between the rollers, offering unique flexibility.
Transmitting compacted data over a wireless LAN
When two or more rollers are used simultaneously in a project, they can establish a network connection via a wireless LAN. The Hummer compaction navigation system determines the current compaction process via a wireless LAN; for example, the system records the number of compaction passes of all rollers and displays the compaction results on all tablets, making it easy for each operator to understand the entire compaction Ground conditions in the area.
Easy to manipulate
The Hummer brand places great emphasis on the intuitive operation of the equipment, and the Hummer compaction navigation system also meets this standard: an easy-to-manage system that allows users to quickly understand how to operate the equipment for better compaction. Plug and play, no configuration changes are required from the start of construction.
Even when the equipment is temporarily suspended or new shifts are started, the Hummer compaction navigation system can quickly provide a stable signal: after the equipment is turned off, the system will continue to maintain the GNSS signal for up to 16 hours, avoiding the system initializing the reception of satellite signals. Waiting time.
Convenient data management
Another great advantage of the Hummer Compaction Navigation System for easy on-site management is the ability to archive data very simply. All data in the system can be easily stored and archived using a standard USB interface. Therefore, Zhunyang Road Company is able to monitor and record the compaction process and compaction quality by itself. Through this system, whether the paving is compacted or the soil is stable, it can meet the construction requirements of continuous compaction control (CCC). (This article is from Wirtgen China)
