Description

Real time enbankment compaction control system with real time process control

The present invention relates to a fill compaction management system for managing the compaction state of the ground in the ground fill process.

The present invention provides a virtual base station formed in a relationship between a plurality of GPS reference station networks; A compaction device equipped with a GPS receiver for receiving location information data from the virtual base station, and a compaction information data collection device for collecting compaction information data; A control center for receiving location information data and compaction information data of compaction equipment in real time from the GPS receiver and compaction information data collection device; And a wireless communication system for transmitting and receiving location information data and compaction information data between the compaction equipment and the control center. Characterized in that consists of.

Filling works are the main processes required for civil engineering work to create a large site, and for the construction of roads, dams and ports. Filling work is mainly performed in order to provide convenience for use by matching the elevation difference between the surrounding area and the work area in the process of large scale site creation. In addition, the filling work may be carried out for the purpose of dispersing the load transmitted to the ground or consolidating the soft ground in the construction of roads and dams.

Filling works consist of soil cutting and excavation processes, soil transport and laying processes, and compaction processes. In particular, the compaction process is a process for securing the strength of the fill ground and preventing settlement, and corresponds to a process that forms the core of the fill work.

However, until now, there has been no systematic management system that can effectively manage the compaction process work. Therefore, the work was carried out by artificial judgment based on the memory and skill of field workers or supervisors. In other words, during the compaction process, the inventors rely on empirical management methods to observe compaction thickness, frequency, speed, and area. And even after the compaction process is completed, the whole soil compaction is managed by the spot test method using plate loading test, site density test, and field permeability test, so that the level of compaction of the entire site cannot be determined. Uniformity could not be proved, and even if the test results were good, it was a probabilistic choice and thus implied distrust.

In order to solve some of these shortcomings, some of them use the landfill compaction management system by DGPS positioning.

The system is configured to store compaction-related information in a storage medium attached to compaction equipment, and separate and process the storage medium separately after each compaction for a certain period. Therefore, if the compaction thickness or compaction section is insufficient later, rework of the compaction section is required with a certain time difference, which leads to an increase in overall air and construction cost. In addition to the driver of the compaction equipment in addition to the operator to manage the storage media installed in the compaction equipment, there was a problem that the service cost is exceeded. At the same time, it was difficult to obtain accurate mobile positioning at a location far from GPS stations.

Second, the present invention is to provide a compaction compaction management system that can improve the work efficiency by reducing the work waiting time by real-time notification of the compaction process data grasped by the control center in the field.

Third, the present invention intends to provide a fill compaction management system that can improve the quality of fill process by enabling accurate moving positioning by introducing a VRS (virtual reference system) using a temporary reference station.

Fourth, the present invention is to provide a fill compaction management system that can reduce the air and construction costs by introducing the scientific and automated fillet compaction management system as described above.

The present invention to solve the above problems is a virtual base station formed in a relationship between a plurality of GPS reference station network; A compaction equipment equipped with a GPS receiver for receiving location information data from the virtual base station and a compaction information data collection device for collecting compaction information data; A control center for receiving location information data and compaction information data of compaction equipment in real time from the GPS receiver and compaction information data collection device; And a wireless communication system for transmitting and receiving location information data and compaction information data between the compaction equipment and the control center. Provides a fill compaction management system capable of real-time process management, characterized in that consisting of.

In addition, since the position information data received from the virtual base station is corrected through DGPS positioning or RTK positioning, precise positioning is possible.

In addition, the location information data and the compaction information data received at the control center is delivered to the operator of the compaction equipment in real time through the work notification device, thereby improving work efficiency.

According to the present invention as described above is expected the following effects.

First, the supervisor can grasp the working situation in real time by transmitting the compaction process data acquired using DGPS positioning or RTK positioning to the control center in real time.

Second, real-time notification of the compaction process data obtained by the supervisor from the control center to the field workers can reduce work waiting time and improve work efficiency.

Third, by introducing a VRS (virtual reference system) using the temporary reference station to the fill compaction management system, it is possible to precisely move the fill process quality can be improved.

Fourth, by introducing a scientific and automated fill compaction management system, it is intended to provide a fill compaction management system that can reduce the number of workers required and reduce air and construction costs.
