Description

Earthworks information management system, method, and a recording medium recording a computer readable program for executing the method

The present invention relates to a system and method for managing earthworks information, and more particularly, to the productivity of earthworks by collecting and processing data generated in all stages of earthworks (survey / design / construction / maintenance) It relates to a system and method for improving and sharing data.

In construction work, earthwork is an important work that accounts for 20 to 30% of the total construction work. However, the survey/design/construction process related to earthworks has a problem in that the work process is segmented and the productivity is low due to the lack of connection between repetitive work and data. In particular, information acquired during design and construction is inevitably subject to design change during the construction process due to the lack of connectivity for each process.

In addition, since the design and construction of earthworks uses the cross-sectional average method based on the two-dimensional design drawing, it is not easy to accurately grasp the construction volume and the precision of schedule management is low.

In addition, in the compaction construction process, which is the final stage of earthworks, it is inefficient because the inspection and construction process are repeatedly performed, and the lack of reliability in the compaction construction result occurs due to insufficient data management related to construction quality. Due to this, it appears that the construction procedure and construction quantity vary according to the subjective judgment of the work manager in the construction process.

Therefore, stable design and construction methods are needed to calculate accurate construction quantities and improve work efficiency in the earthworks process. To this end, it is necessary to develop standardized processes with high precision and flexible data management.

According to this configuration, a separate test can be omitted by automatically measuring the compaction degree information while the compaction construction equipment is in operation, so that the entire earthwork schedule can be shortened because the operation of the equipment does not have to be stopped for the test. By including and sharing compaction state information in BIM information, it can be easily utilized without preprocessing in subsequent work after earthworks are completed.

② Generate 3D original ground data

Using the 3D location information coordinates (X, Y, Z) and ground layer information (thickness of soil layer, weathered rock, bedrock, etc.) acquired through ground drilling survey, the layer boundaries of each borehole are connected, converted into 3D, and stored.

③ If ground property information is insufficient, ground property prediction and interpolation for the non-bored section

In the case of lack of ground properties, use the kriging technique (a geostatistical technique that predicts the value with a linear combination of already known values in order to find the characteristic value at the point of interest ) or machine learning technique for the micro-situ section. to predict and interpolate and use it as data for generating 3D ground data

④ Generate 3D original topography/ground BIM data

By integrating the ground and terrain data created in 3D, combining them into a single 3D model, converting to BIM (Building Information Modeling) data and saving it

⑤ Original topography/ground BIM data extraction and design utilization

The generated BIM data is extracted in *.obj or *.fbx for 3D terrain information and in *.XML for property information and used in commercial civil engineering software (Autocad - Civil3D, Bently - InRoad, etc.) Use as 3D design data for planned topography and ground

2) Virtual simulation for review of design results using 3D BIM data

⑥ 3D design using 3D BIM data

In the design stage using 3D BIM data, the planned (facility, topography and ground shape at the time of final completion) is designed in 3D for the topography and ground to create BIM data, and at this time, the original topography and ground and the planned topography and ground are created. Calculate the construction quantity (construction amount-schedule, cumulative amount, input equipment, cutting/filling amount, etc.)

⑦ 3D virtual construction simulation to review constructability of design results

In order to review the construction quantity calculated in the design process, a 3D virtual space is created based on the 3D original terrain/ground BIM data of ④ above, and the construction quantity calculated in the design process is set (schedule, unit price, etc.) and arranging (equipment, movement path), reproducing, simulating with reinforcement learning, and comparing design results and virtual construction results.

⑧ Comparison of design results and virtual construction simulation and design update

After comparing the design result and the virtual construction result through 3D virtual construction simulation, if the difference in construction quantity output exceeds 5%, the process of ⑥ to ⑦ above is repeated to derive the optimal value and update to the optimal design result.

Coordinates of the moving path of the compaction construction equipment are acquired with a GPS device, and the degree of compaction is measured with an accelerometer to measure the repulsive force of the ground. It is necessary to visualize the acquired information using real-time sensors because it is necessary to monitor the condition of compaction and the number of movements rather than observing changes in volume, such as dumping.)

Since compaction construction is based on compaction by floor (thickness of about 30cm) in terms of construction standards, the compaction state of each floor is identified by considering the GPS coordinate value and the compaction movement path.

⑭ Sharing of final earthwork DB after compaction construction

Compaction construction is the final stage of earthworks, so that it can be used in subsequent processes (road pavement, facility installation, etc.) after the final earthworks are completed. ) and store it, and attribute information such as ground layer information is extracted by defining and saving data in *.XML format to be used in subsequent processes.
