Abstract
Description
Technical Field
[0001] This application relates to the field of hydrogeological exploration and geotechnical engineering testing technology, and in particular to a device and testing method for real-time monitoring of borehole confined water pressure. Background Technology
[0002] Confined aquifers are groundwater that fills an aquifer between two impermeable layers. In engineering construction, mining, and water conservancy and hydropower projects, the hydraulic pressure test of confined aquifers is a fundamental task for obtaining engineering geological parameters. It is of great significance for evaluating the groundwater flow field, predicting the risk of water inrush, and guiding the design of engineering dewatering and support systems.
[0003] Traditional methods for reading the pressure of confined borehole water often rely solely on mechanical pressure gauges for manual on-site readings. This approach has several drawbacks: First, the readings are significantly affected by human factors, typically only providing an instantaneous reading and failing to reflect the pressure stabilization process over time. Second, mechanical readings are difficult to record continuously digitally, hindering integration with subsequent work such as permeability parameter calculations and seepage field evolution analysis. Third, when measuring only pressure parameters, it is difficult to simultaneously acquire water temperature information related to the confined water condition and sensor calibration. Fourth, some electronic pressure measurement systems require independent external data acquisition boxes and multi-stage transfer lines, resulting in long connection links and relatively cumbersome on-site rapid reading and data processing procedures. Therefore, there is an urgent need to design a borehole confined water monitoring device and testing method that can simultaneously acquire both pressure and temperature, reduce the need for external acquisition boxes and intermediate transfer links, and extract in-situ stable pressure based on continuous pressure-time curves. In hydrogeological tests such as pumping tests and injection tests, the change of water head in the observation well over time is an important basis for calculating parameters such as permeability coefficient, hydraulic conductivity, and storage coefficient. If only manual intermittent readings are relied upon, it is difficult to fully record the dynamic response of the water head in the observation well during the pumping and injection process.

[0059] The data transmission component includes a data transmission line connected to the tail of the integrated pressure and temperature sensor.

[0064] refer to Figure 4 According to another aspect of this application, a test method for real-time monitoring of borehole confined water pressure is also included, comprising the following steps:
[0065] S1. Install the orifice sealing cap 1 onto the borehole sleeve to seal the borehole.
[0066] S2. Install the mechanical pressure gauge 3 on one branch pipe of the pipeline diversion adapter 5, install the integrated pressure and temperature sensor 6 on the rear end of the control valve 4, and connect the integrated pressure and temperature sensor to the data processing terminal via the data transmission component and the data acquisition and conversion module 9.
[0067] S3. Turn on the data acquisition software in the data processing terminal and turn on the control valve 4 to allow the pressurized water in the borehole to enter the pipeline diversion adapter and act on the mechanical pressure gauge and the pressure-temperature integrated sensor respectively.
[0068] S4. Read the on-site pressure changes and make pressure predictions through the mechanical pressure gauge 3. Collect pressure and temperature signals in real time through the integrated pressure and temperature sensor 6. The data processing terminal displays the test data in real time, records it continuously, and generates pressure-time change curves and temperature-time change curves.
[0069] S5. After the test is completed, close the control valve 4, and disconnect the connection between the data processing terminal, the data acquisition and conversion module 9, the data transmission component and the pressure and temperature integrated sensor 6 in sequence, while keeping the mechanical pressure gauge 3, the pipeline diversion adapter 5 and the orifice sealing cap 1 closed.
[0070] It should be noted that before installing the integrated pressure and temperature sensor, the initial pressurized water pressure inside the borehole is pre-judged using a mechanical pressure gauge. The data processing terminal receives and parses the pressure and temperature signals output by the integrated pressure and temperature sensor via the RS485 communication protocol, and these signals are converted and transmitted by a portable data acquisition and conversion module that can be directly plugged into the data processing terminal. After the test, a data processing step is also included: exporting the pressure and temperature data collected and stored in the data processing terminal, and analyzing the data curves in conjunction with the on-site test time, measuring point number, and borehole information to extract the pressure and temperature parameters in the stable phase. The device can be used for dynamic monitoring of observation holes in pumping or injection tests. The data acquisition and processing program generates a head-time change curve based on the pressure data collected by the integrated pressure and temperature sensor; the temperature data is used to verify or correct the water density.
[0071] refer to Figures 1-4 The apparatus and method of this application will be described below through a specific example.
[0072] The method for in-situ measurement of borehole confined water pressure using the device of the present invention is as follows:
[0073] Step 1, Connecting the device
[0074] Install the orifice sealing cap 1 onto the borehole casing, and tighten and fix the orifice sealing cap 1 with the horizontal handle 2 to seal the borehole. Install the mechanical pressure gauge 3, valve 4, and pressure-temperature integrated sensor 6 sequentially at each interface of the tee pipe 5. The mechanical pressure gauge 3 is used to read the pressure value directly on site, and the pressure-temperature integrated sensor 6 is used to collect the pressure and temperature signals of the pressurized water in the borehole. Then connect the pressure-temperature integrated sensor 6 to the cable 7. The other end of the cable 7 is connected to the RS485 to USB reader 9 through the aviation socket interface 8. Connect the RS485 to USB reader 9 to the computer to complete the overall connection of the test device.
[0075] Step 2, On-site measurement and recording
[0076] Turn on the data acquisition software on the computer and check if the communication status of the integrated pressure and temperature sensor 6 is normal. Then, slowly open the valve 4 to allow the pressurized water in the borehole to enter the tee pipe 5 and be transmitted to the mechanical pressure gauge 3 and the integrated pressure and temperature sensor 6 respectively. During the test, the staff observes the pressure change in the borehole in real time through the mechanical pressure gauge 3 and judges whether there is a risk of exceeding the range. At the same time, the pressure and temperature sensor 6 transmits the collected pressure and temperature signals directly to the computer via the cable 7, aviation socket interface 8 and RS485 to USB reader 9. The computer displays the test data in real time, records it continuously and generates a pressure / temperature-time change curve. When the pressure / temperature-time change curve tends to stabilize, the in-situ measurement and real-time monitoring and recording of the pressurized water pressure in the borehole is completed.
[0077] Step 3, disassemble the device.
[0078] After the on-site measurement is completed, first close valve 4 to stop the pressurized water in the borehole from continuing to enter the test system; after the residual pressure in the tee pipe 5 and each connecting component is released, disconnect the RS485 to USB reader 9, aviation socket interface 8, cable 7 and pressure and temperature integrated sensor 6 in sequence, then disassemble pressure and temperature integrated sensor 6, leaving mechanical pressure gauge 3, valve 4, tee pipe 5 and orifice sealing cap 1 to achieve orifice sealing, which will facilitate subsequent measurement work.
[0079] Step 4, Data Processing
[0080] The raw pressure and temperature data collected on-site and stored in the computer are exported and processed in conjunction with the on-site test time, measuring point number and borehole information. During the pumping or injection test, the integrated pressure and temperature sensor 6 continuously collects pressure and temperature signals in the observation borehole. The data acquisition and processing program generates a head-time change curve. This curve can record the dynamic response of the head in the observation borehole during pumping or injection, providing continuous monitoring data for subsequent hydrogeological parameter calculation and test process analysis, and finally forming corresponding test records and data analysis results.
