[0002] Pore water pressure measurement refers to the pressure of groundwater in soil or rock, which acts between particles or pores. It is divided into static pore water pressure measurement and excess pore water pressure measurement. For highly permeable soil under no-flow conditions, the pore water pressure measurement is approximately equal to the static water pressure measurement without water flow, and it is often achieved by burying a series of piezometers at the soil slope site and measuring the head height after stabilization.

[0033] Please refer to Figures 1-3 , a groundwater pore water pressure monitoring device, including a detection component 1 and a fixture component 2 for clamping the detection component 1. The setting of the fixture component 2 facilitates fixing the detection component 1 in the soil, and the setting of the detection component 1 facilitates detecting the water pressure of groundwater. The detection component 1 includes a detection tube 13, and a conical protective head 15 is installed at one end of the detection tube 13.

A plurality of equidistant arc-shaped openings are formed on the outer wall of the protective head 15, and a filter screen 16 is fixedly connected to the inner wall of the arc-shaped opening. The filter screen 16 in the arc-shaped opening facilitates filtering groundwater and introducing it into the detection tube 13. The protective head 15 is made of corrosion-resistant material to enhance its durability in a harsh groundwater environment. Three equidistantly distributed rectangular openings are formed on the outer wall of the protective head 15, and a connection component 19 is installed on the inner walls of the three rectangular openings. The setting of the connection component 19 facilitates quickly installing the protective head 15 on the detection tube 13.

[0034] During use, the setting of the detection component 1 facilitates detecting the water pressure of groundwater, and the setting of the fixture component 2 facilitates fixing the detection component 1 at a specified position for stable detection of groundwater pressure. The conical protective head 15 is made of anti-corrosion material, thereby increasing the service life of the protective head 15. The setting of the filter screen 16 facilitates filtering groundwater and introducing it into the detection tube 13, and the setting of the connection component 19 facilitates quickly disassembling and assembling the protective head 15.

[0035] Refer to Figure 5, three rectangular grooves 17 are provided at equal distances on the outer wall of the detection tube 13. The arrangement of the rectangular grooves 17 facilitates the installation in cooperation with the connection assembly 19. Limit grooves 18 are provided on the inner walls on both sides of the three rectangular grooves 17. The arrangement of the limit grooves 18 facilitates the fixing of the connection assembly 19 in the rectangular grooves 17. A pressure sensor is fixedly connected to the inner wall of the detection tube 13. A pressure sensor is a device or apparatus that can sense pressure signals and convert the pressure signals into available output electrical signals according to certain rules. A pressure sensor usually consists of a pressure-sensitive element and a signal processing unit. According to different types of test pressures, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors, and absolute pressure sensors. One end of the detection tube 13 is fixedly connected with a connection cable 14 connected to the pressure sensor. The water pressure of groundwater can be conveniently detected through the pressure sensor in the detection tube 13. The connection cable 14 is designed to be waterproof and pressure-resistant to ensure the stable transmission of data under complex geological conditions. At the same time, the outer part of the connection cable 14 is coated with wear-resistant material to reduce the risk of damage to the line due to friction.

The limit seats 22 are slidably installed in the installation cavity 21. The specifications of the limit seats 22 match the specifications of the limit grooves 18. When the limit seats 22 extend out, they are directly inserted into the limit grooves 18, thereby facilitating the fixing of the connection seat 20 in the rectangular groove 17, and thus facilitating the installation of the protective head 15 on the detection tube 13. Through the provision of the installation cavity 21 in the connection seat 20, the sliding installation of the limit seats 22 is facilitated. When the limit seats 22 are inserted into the limit grooves 18, the protective head 15 can be installed. The specifications of the connection seat 20 match the specifications of the rectangular groove 17.

[0037] Refer to Figure 7, on both inner walls of the installation cavity 21, there is a same screw rod 23 rotatably connected. The setting of the installation cavity 21 facilitates the rotational installation of the screw rod 23. And on the outer wall of the screw rod 23, there is a trapezoidal block 24 screwed. The trapezoidal block 24 is slidably connected to the inner wall of the installation cavity 21. When the screw rod 23 rotates, it drives the trapezoidal block 24 to move. In order to prevent the trapezoidal block 24 from rotating along with the screw rod 23, the trapezoidal block 24 is slidably installed in the installation cavity 21. On one outer wall of the connecting seat 20, there is a rotating disk 25 rotatably connected. And one end of the transmission shaft of the rotating disk 25 is fixedly connected to the screw rod 23. The setting of the rotating disk 25 facilitates manually driving the screw rod 23 to rotate.

One end of the two limiting seats 22 is slidably connected to the trapezoidal block 24. Through the setting of the installation cavity 21, it is convenient to rotatably install the screw rod 23. When the screw rod 23 rotates, it is convenient to directly drive the trapezoidal block 24 to move. When the trapezoidal block 24 moves, it directly drives the two limiting seats 22 to act. The setting of the rotating disk 25 facilitates directly driving the screw rod 23 to rotate.

[0038] Refer to Figure 2 and Figure 3 , the fixture assembly 2 includes a fixture base 3. And on the top outer wall of the fixture base 3, there is a circular opening 8. The diameter of the circular opening 8 on the fixture base 3 is larger than the diameter of the test tube 13, thus facilitating the test tube 13 to pass through the circular opening 8. On both outer walls of the fixture base 3, there are installation ears 4 fixedly connected. The two installation ears 4 are symmetrically arranged on the fixture base 3. And on the top outer walls of the two installation ears 4, there are threaded openings. In the inner walls of the two threaded openings, there are adjusting screw rods 5 screwed. And on the bottom outer walls of the two adjusting screw rods 5, there are taper tips 6 fixedly connected. When the adjusting screw rod 5 rotates, it drives the taper tip 6 to move, thus facilitating driving the taper tip 6 to insert into the soil. By rotating the adjusting screw rod 5, the taper tip 6 is driven to insert into the soil. The circular opening 8 in the fixture base 3 facilitates the installation of the test tube 13.

[0039] Refer to Figures 2-3 , in the inner wall of the circular opening 8, there are two symmetrically arranged arc-shaped openings. And in the inner walls of the two arc-shaped openings, there are T-shaped seats 12 slidably connected. The two T-shaped seats 12 are symmetrically arranged on the fixture base 3. On the opposite outer walls of the two T-shaped seats 12, there are arc-shaped plates 9 fixedly connected. The T-shaped seats 12 slide in the arc-shaped openings, which further facilitates driving the two arc-shaped plates 9 to move through the T-shaped seats 12. The setting of the arc-shaped plates 9 facilitates clamping the test tube 13. Through the two arc-shaped openings in the circular opening 8, it is convenient to install the T-shaped seats 12. When the T-shaped seats 12 slide, it is convenient to drive the arc-shaped plates 9 to clamp the test tube 13, thus facilitating fixing the test tube 13.

[0040] Refer to Figures 2-3, both inner walls on both sides of the fixture base 3 are rotatably connected with two bidirectional screws 10. The two bidirectional screws 10 are symmetrically arranged in the fixture base 3, and one end of each of the two bidirectional screws 10 is fixedly connected with a synchronous pulley. The same synchronous belt 11 is connected between the two synchronous pulleys. The cooperation between the synchronous pulley and the synchronous belt 11 enables the two bidirectional screws 10 to rotate synchronously. By arranging synchronous pulleys on the bidirectional screws 10 and connecting the same synchronous belt 11 between the two synchronous pulleys, through the cooperation between the synchronous belt 11 and the synchronous pulleys, it is convenient to make the two bidirectional screws 10 rotate synchronously.

[0041] Refer to Figures 2-3 , two T-shaped seats 12 are respectively screwed on the outer walls of the two bidirectional screws 10. One side outer wall of the fixture base 3 is rotatably connected with a rotating part 7, and one end of the transmission shaft of the rotating part 7 is fixedly connected to one of the bidirectional screws 10. By rotating the rotating part 7 to drive one of the bidirectional screws 10 to rotate, and then through the cooperation between the synchronous pulley and the synchronous belt 11, the two bidirectional screws 10 rotate synchronously, thereby driving the two T-shaped seats 12 to move towards or away from each other, so as to conveniently drive the arc-shaped plate 9 to clamp and fix the test tube 13.

[0042] The implementation principle of this application is as follows: When in use, first determine the position of the water pressure detection, and then pass the test tube 13 through the round opening 8. When the position of the test tube 13 is determined, rotate the rotating part 7. When the rotating part 7 rotates, it drives the bidirectional screw 10 to rotate. The two bidirectional screws 10 are connected by a synchronous pulley and a synchronous belt 11, so as to conveniently make the two bidirectional screws 10 rotate synchronously. When the bidirectional screw 10 rotates, it drives the T-shaped seat 12 to drive the two arc-shaped plates 9 to move towards or away from each other. When the two arc-shaped plates 9 move towards each other, it is convenient to directly fix and clamp the test tube 13. Then rotate the two adjusting screws 5 to drive the conical tips 6 to insert into the soil, so as to conveniently fix the detection assembly 1 at the specified position. The groundwater enters the test tube 13 through the filtration of the filter net 16, and the pressure sensor in the test tube 13 directly detects the water pressure of the groundwater.

[0043] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
