Description

Technical Field

[0001] This invention relates to the field of resistivity detection in urban shield tunnels, and particularly to an electrical detection device and method using the shield cutterhead and shield as power supply electrodes. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] To address urban traffic congestion, subways have become an indispensable transportation measure in densely populated cities. Shield tunneling is the mainstream construction method for urban subways; however, shield tunneling for urban subways also faces numerous challenges. For example, the complex underground geological conditions in cities, including karst caves, weak interlayers, and water-rich zones, can easily trigger disasters such as sudden water inrushes, ground instability, and surface subsidence. These can lead to severe economic losses and casualties, posing a serious threat to the safety of shield tunnel construction.

[0004] It is understood that the DC resistivity method can effectively identify groundwater, faults, karst caves, mudstone, hard rock, and other geological structures, and can treat risk areas not yet excavated to avoid disasters such as sudden water inrush and ground instability, thus ensuring the safety of construction personnel. However, the following problems exist when conducting detection in shield tunnels:

[0005] (1) Common detection methods require the placement of measuring electrodes on the tunnel face and power supply electrodes on the tunnel sidewalls, which requires some space in front of the tunnel face and affects the tunnel excavation period; (2) Detection instruments need to be transported manually, and each detection requires the re-arrangement of measuring electrodes and power supply electrodes, which reduces detection efficiency and increases manpower consumption; (3) Traditional shield tunnel detection requires workers to enter the shield cutterhead to set up electrodes, and the safety of workers cannot be guaranteed.

[0041] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0042] It should be noted that the following detailed descriptions are exemplary and intended to provide further illustration of the invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0043] In this implementation, an electrical detection device using the shield cutterhead and shield as power supply electrodes is proposed, such as... Figure 1 and Figure 2 As shown, it includes: transmitter unit 3, receiver unit 5, transmitting electrode unit and receiving electrode unit.

[0044] Specifically, the transmitter unit 3 includes: a power filtering module, a power switch, a signal decoding module, a constant voltage control module, a constant current control module, a voltage data receiving module, a current data receiving module, and an indicator light;

[0045] The receiver unit 5 includes: a power switch module, a data acquisition module, a Wi-Fi module, a GPS, a data transmission module, an electrode information transmission module, and a receiving electrode access module;

[0046] The transmitting electrode unit includes: a shield cutterhead 8 and a shield shield 7;

[0047] The receiving electrode unit includes: a measuring electrode 6 ( Figure 2 Only the first measuring electrode, the second measuring electrode, and the third measuring electrode are shown.

[0048] In this implementation, the preferred method is as follows: Figure 1 As shown, the transmitter unit 3 integrates a power filtering module, a power switch, a signal decoding module, a constant voltage control module, a constant current control module, a voltage data receiving module, a current data receiving module, and indicator lights. The transmitter unit 3 is mounted in the shield machine main control room 2, and the transmitter unit 3 is controlled by the shield machine main control room computer in the main control room 2 to transmit, which facilitates the operation of the transmitter unit by the operator. A cable 4 is also provided to connect the transmitter unit 3 to the shield machine main control room computer.

[0049] More specifically, the transmitter unit 3's transmitter switch is connected to the constant voltage control module and the constant current control module. The AC power supply is filtered by the EMC filter unit (i.e., the power supply filter module) and then input into the transmitter unit. The transmitter mode and transmitter current are set by the shield tunnel main control room computer in the main control room 2, and the set current is output by the signal decoding module.

[0050] The 220V AC power is filtered by the power supply filter module and the power switch, then converted into DC power by the AC / DC module, and finally converted into DC power suitable for detection by the DC / DC module.

[0051] The signal interpretation module in this implementation is used to receive the transmission control signals set in the computer in the shield tunnel main control room or transmitted from the ground, and to control the relevant units inside the transmitter unit 3 to complete the transmission work in the specified mode.

[0052] The constant voltage control module and constant current control module in this implementation are used to execute the pre-set transmission task and control the magnitude of the transmission current and transmission voltage.

[0053] The transmit switch in this implementation is used to control the transmit current and stop the transmit current of transmitter unit 3.

[0054] The indicator lights in this implementation are used to indicate the status of transmitter unit 3. The off state indicates that transmitter unit 3 is powered off and not connected to power. The red state (i.e., the first color) indicates that power is connected but no transmission is being performed. The green state (i.e., the second color) indicates that transmitter unit 3 is transmitting.

[0055] The current data receiving module and voltage data receiving module in this implementation are used to collect the magnitude of the transmitted current and voltage after the transmitter unit 3 transmits the current, and transmit them to the shield tunnel main control room computer. The shield tunnel main control room computer displays the actual transmitted signal of the transmitter unit 3.

[0056] In this implementation, the power switch of transmitter unit 3 is controlled by the computer in the shield tunnel main control room. When the red light of transmitter unit 3 is on, the desired transmission mode is selected in the control software of the computer in the shield tunnel main control room. The signal decoding module of transmitter unit 3 receives the instructions from the computer in the shield tunnel main control room and, according to the instructions, activates the constant voltage control module or the constant current control module to transmit current. After the transmission parameters are set, the transmission switch is controlled by the computer in the shield tunnel main control room to transmit current. When the indicator light of transmitter unit 3 is green, it indicates that transmitter unit 3 is transmitting normally.

[0057] In this implementation, the preferred method is as follows: Figure 2 As shown, receiver unit 5 integrates a power switch module, a data acquisition module, a Wi-Fi module, GPS, a data transmission module, and an electrode information transmission module. The power switch module of receiver unit 5 is turned on by the computer in the shield tunnel main control room. The received data is collected by the data acquisition module and then transmitted to the computer in the shield tunnel main control room for interpretation and processing via the data transmission module and the Wi-Fi module.

[0058] The functions of each component of the receiver unit are as follows:

[0059] The receiving electrode access module connects each measuring electrode 6 to the computer in the shield tunnel main control room and is used to connect the measuring electrode 6 to the receiver unit 5.

[0060] The electrode information transmission module is used to transmit the connection method of the receiving electrode on the receiver unit 5 and display it on the computer in the shield tunnel main control room. This module transmits the information to the computer in the shield tunnel main control room after the measuring electrode 6 is connected and the power switch is turned on.

[0061] A Wi-Fi module is used for wireless connection to the computer in the tunnel boring machine's main control room.

[0062] GPS is used to determine the geographical location of receiver unit 5.

[0063] In this implementation, receiver unit 5 is mounted on the tunnel boring machine (TBM). Before detection, the receiving electrode unit must be set up, the TBM main control room computer is connected to the receiving electrode access module, and the power switch of the receiver unit is turned on. The TBM main control room computer is connected to receiver unit 5. After the connection is completed, the electrode information transmission module will feed back the electrode access status to the TBM main control room computer and display it in specific software. The data measured during detection will be collected by the data acquisition module of receiver unit 5, and then sent to the Wi-Fi module through the data transmission mode. Finally, it will be stored and displayed in the TBM main control room computer.

[0064] In this implementation, the transmitter unit 3 is connected to the shield machine main control room computer via cable 4. When the transmitter unit 3 transmits current, it enables the shield shield 7 and the shield cutterhead 8 to be powered. More specifically, in this implementation, the power supply method is that the transmitter unit 3 mounted in the shield machine main control room 2 is connected to the shield shield 7 via cable 4, and the main control room computer in the main control room 2 controls the transmitter unit 3 to transmit current.

[0065] The electrode receiving unit in this implementation includes a measuring electrode 6, which is a common measuring electrode. It is arranged in three circles in the gap of the shield segment 1 behind the shield machine (the number of circles can be set according to the detection requirements, for example, one circle, two circles, four circles or more circles can be set).

[0066] like Figure 3As shown, before conducting the detection, the transmitter unit 3 located in the main control room 2 is connected to the shield shield 7 of the tunnel boring machine using cable 4, so that the shield shield 7 and the cutterhead 8 of the tunnel boring machine become power supply electrodes to achieve power supply to the tunnel face. The measuring electrode 6 is inserted into the gap of the shield segment and connected to the receiver unit 5 using cable. The power of the receiver unit 5 is turned on and connected to the computer in the main control room of the tunnel boring machine through the Wi-Fi module. After all the devices are connected, the computer in the main control room of the tunnel boring machine controls the transmitter unit 3 to transmit current and receives the data obtained by the receiver unit 5. Then, the data is analyzed and processed to determine the specific situation of the area 9 to be measured in front of the tunnel face and to take relevant actions.

[0067] During the exploration, since the shield cutterhead 8 and shield shield 7 are used as power supply electrodes, the shield machine does not need to retract. After determining the exploration method to be used, the measuring electrodes 6 are arranged in the gaps of the shield segments and connected to the receiver unit 5. The transmitter unit 3 is connected to the shield cutterhead 8 through a rotating power supply device. After debugging the equipment in the tunnel, the transmission parameters are set through the computer in the shield main control room. Then, the transmitter unit is controlled by the computer in the shield main control room to launch the probe and start the exploration operation. After the exploration is completed, the collected data is processed in time in the computer in the shield main control room to obtain the specific situation of the target area before making a decision on whether to continue the tunneling.

[0068] Specifically, such as Figure 4 As shown, the tunnel boring machine (TBM) stops tunneling, determines the detection method, arranges the measuring electrodes at the tail of the shield, connects the receiver and the electrodes, connects the transmitter and the electrodes, connects the computer, sets the detection parameters, performs detection operations, analyzes the results, and determines whether tunneling can continue. If yes, the TBM continues tunneling; if no, it handles the anomalies in the detection area and then continues tunneling.

[0069] More specifically, this implementation provides a specific method for operating the device, including:

[0070] Step 1: Deploy electrodes and connect instruments. Connect transmitter unit 3 to shield shield 7 in the tunnel boring machine. Shield cutterhead 8 and shield shield 7 serve as power supply electrodes and are connected by cable. At the rear of the tunnel boring machine, arrange measuring electrodes 6 in the gaps of the shield segments, deploying three circles, and connect them to receiver unit 5.

[0071] Step 2: Turn on the instrument, connect transmitter unit 3 to the external power supply, turn on the switch of transmitter unit 3, wait for the indicator light to turn red, turn on the power switch of receiver unit 5, connect receiver unit 5 and the shield tunnel main control room computer with Wi-Fi module, start the detection software in the shield tunnel main control room computer to prepare for the detection operation;

[0072] Step 3: Set the transmission parameters. After connecting the transmitter unit 3, receiver unit 5 and the shield tunnel main control room computer, select the transmission mode, duty cycle, power supply cycle, power supply and number of acquisition channels for transmitter unit 3 through the shield tunnel main control room computer.

[0073] Step 4: Detection and measurement. After confirming that there are no construction personnel at the shield cutterhead 8 and shield shield 7, the detection begins. The shield main control room computer in the main control room controls the constant current high power transmitter module to transmit the current and checks the indicator light of transmitter unit 3, which is green at this time.

[0074] Step 5: Viewing and saving data. All data from the detection will be stored in the computer in the shield tunnel main control room. The detection data will be processed by specific data processing software in the shield tunnel main control room computer to explain the specific situation of the area to be measured 9.

[0075] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
