Background Art

[0002] During the excavation process of civil engineering, the traditional method of collecting construction geological information and compiling reports requires geologists to enter and compile all the data of each cycle one by one. This is not only labor-intensive and time-consuming, but also prone to human errors, causing unnecessary troubles, especially in underground projects with many engineering parts and frequent compilation, which will cause a great burden on human resources. How to avoid duplication of work, improve work efficiency, and reduce the error rate is an urgent problem to be solved in the construction geological work of civil engineering.

[0003] The digitization, informatization and intelligence of engineering geology are the directions that the engineering industry urgently needs to develop. Exploring effective, fast, targeted and systematic geological information during the construction geological period is one of the technologies to be developed, and it is also the data basis for establishing a full life cycle BIM model. At present, in the field of underground cavern geological information collection, a structural surface automatic collection system based on three-dimensional laser scanning and image processing and a personal handheld mobile system have been developed, but they have high requirements for the construction environment of underground caverns and tunnels, such as light, noise, air, dust, and slag. These factors have a great impact on the recognition results. At present, there is no mature, stable and widely applicable system that can completely solve this problem. Although the field data collection has been automated, the current technical level cannot meet the accuracy requirements. Later data processing still requires manual intervention and interpretation, which may take more time and reduce efficiency. Summary of the invention

The system collects data based on a tablet computer on the mobile end, and connects to the total station via Bluetooth to assist in the collection of geological feature points, lines, surfaces and other geological information. After completion, the data is uploaded to the cloud server through the 4G signal in the cave, and the data is processed and analyzed on the computer end.

[0028] like Figure 2 As shown, the system includes a total station connection module, a data acquisition module, a data storage module, and a data processing module. The basic information of the project is input in advance into the data acquisition system at the computer port, and the typical section and its applicable pile number range are defined.

[0029] After the surveying department has completed the installation and calibration of the total station, the geological technicians open the project management system collection system customized for the mobile terminal and connect to the total station with the help of the Bluetooth module. The geodetic coordinates (X / Y / Z) collected by the total station are interacted with the mobile terminal data to accurately collect field data.

[0030] Open the data collection module in the mobile application, select the project and project location, and input and select information in the three sub-directories of project overview, section definition, and excavation cycle.

[0031] like Figure 3 As shown, the information collected on its interface includes project overview, which records basic descriptive information such as the project's scale, location, person in charge, adopted specifications, and surrounding rock classification standards.

[0032] exist Figure 3 Select the section definition module in the interface to define the dimensions of different excavation sections of the upper horizontal tunnel (HRT). The section definition can also be automatically imported in the computer-side data management system in advance through .Dwg / .Dxf format files.

[0033] exist Figure 3 Select the excavation cycle menu in the interface to collect information from the four sub-menus: cycle information, display map drawing, geological information and image information.

[0034] The following steps are used to collect excavation cycle information: Step 1: If Figure 2 As shown, basic information is collected for each new excavation cycle, including project location [upper flat tunnel], cycle number

[010] , cycle pile number m [30.0~33.00], excavation elevation m [none], excavation method [drilling and blasting method], excavation direction [azimuth 270°], blasting time [9:00 am, October 30, 2021], burial depth m

[70] , groundwater [dry], cataloging time [16:00 pm, October 30, 2021, cataloging personnel [Zhang San], verification personnel [Li XX].

[0035] Step 2: Enter the upper horizontal tunnel [HRT] display drawing module, select the excavation section as Type A, such as Figure 4 As shown, the contour lines are defined according to the section and the tunnel face as the basic plane base map for on-site geological line recording. Figure 4 The left side is the geological information display module, and the right side is the tunnel face display map catalog area. According to the specific geological conditions on site, click on different line types such as geological division, lithology, structural surface, and set the attributes. The attribute settings of joints are as follows: Figure 4 As shown. Geological structure categories include joints, long joints, faults, deformation zones, dislocation zones, fracture zones, and dykes, and attributes include number, occurrence, spacing, opening, roughness, filling, and weathering grade. The tablet computer gyroscope is called in the lower left corner of the screen to realize the automatic occurrence measurement function of the electronic compass, which is convenient for on-site collection of structural surface occurrence.

[0036] Complete the attribute setting of the line, draw different lines, and use a stylus or total station to draw lines. For the face, the origin of the catalog coordinates O is located in the middle of the tunnel, the horizontal axis is the X axis, and the vertical axis is the Y axis. The system can generate corresponding base maps according to different sections, and convert the three-dimensional geological information coordinates collected by the total station into two-dimensional coordinates according to the rules and automatically draw them on the display map. And it can perform plane fitting according to geological feature points, automatically calculate the plane occurrence, and check with the on-site compass data.

[0037] Draw the side wall display map and collect geological information such as Figure 5 As shown in the figure, it is similar to the tunnel face. The length of the side wall display diagram is consistent with the side wall and the perimeter of the tunnel face, and the width is consistent with the excavation footage length of this cycle. For the side wall display diagram, the origin of the catalog coordinates is set at the starting point of the tunnel pile number, such as Figure 5As shown, the three-dimensional coordinates measured by the total station are converted into catalog coordinates through mathematical rules and automatically drawn on the display diagram.

[0038] After the display map and geological information collection are completed, click the Save button to complete the automatic saving of the information in this cycle, and upload it to the server with the help of wireless network.

For the GSI value, the empirical formula is also used for conversion (GSI=0.5RQD+1.5R4, RQD is the integrity of the rock mass, and R4 is the structural surface state value of the RMR method).

[0040] Step 4: Collect image information of the excavation cycle, such as Figure 7 Click the corresponding button to call the camera function of the mobile tablet to collect photos of different parts of the tunnel. After completion, click to save to the local and database, and can be updated and downloaded on the computer.

To ensure that the data is not lost, each operation of the mobile port is automatically saved. Figure 1 As shown, when there is no network, the data is directly stored locally, and when there is a network, it is automatically uploaded to the cloud server.
