Description

Technical Field

[0001] This utility model relates to the field of water pressure testing technology, and in particular to a water pressure testing device for engineering geological exploration. Background Technology

[0002] Engineering geological surveys provide geological information for engineering design and construction in various engineering projects. Water pressure testing is a commonly used in-situ testing method to determine the permeability characteristics of soil and rock masses. The water pressure testing device used in engineering geological surveys achieves the test by injecting water at a certain pressure into the borehole. Based on the water injection volume and pressure data, the permeability coefficient parameters of the soil and rock masses are accurately calculated, helping engineers to accurately assess the permeability and stability of the soil and rock masses, and providing a basis for the formulation of subsequent engineering plans.

[0003] In the field of existing engineering geological exploration technology, water pressure testing devices have been widely used. Traditional water pressure testing devices mainly consist of a water supply system, a pressure control system, a measurement system, and borehole connection components. The water supply system is responsible for providing the water required for the test, the pressure control system can adjust the water pressure, and the measurement system can monitor the water injection volume and pressure in real time, and can complete the entire process and operation of water pressure testing.

The existing equipment pumps water from the storage tank through the water pressure testing equipment into the borehole, which can ensure the supply of water pressure. However, due to poor sealing, the water pump cannot deliver water pressure stably during operation. The internal pressure during the water pressure test is insufficient, resulting in inaccurate water pressure test data. This seriously affects the reliability of engineering geological survey results and produces erroneous data for the formulation of subsequent engineering design and construction plans.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 3 and Figure 5This utility model provides an embodiment of a water pressure testing device for engineering geological exploration, comprising a water inlet pipe 1 for conveying water, a water pump 3 fixedly connected to the left side of the water inlet pipe 1 for pressurizing the water flow, a booster 4 connected to the rear side of the water pump 3 for increasing the water flow pressure, an air tank 5 fixedly connected to the left side of the booster 4 for storing air, stabilizing the pressure, and ensuring the continuity and stability of the water flow pressure, and a high-pressure water pipe 6 connected to the left side of the air tank 5 for transferring the pressurized and stabilized high-pressure water to the water flow. Water flow is transported via a high-pressure water pipe 6. A flow converter 7 is connected to the left side of the high-pressure water pipe 6, which changes the direction of the water flow. A steel pipe 10 is threadedly connected to the bottom of the flow converter 7, serving as a water transmission channel to deliver the water to a designated location for a pressure test. A sealing bolt 8 is threadedly connected to the top of the steel pipe 10 to prevent leakage and ensure that the water flows in a closed environment during the test. A pressure relief pipe 14 is threadedly connected to the bottom of the steel pipe 10, used for pressure testing during the experiment. The bottom of the pressure relief pipe 14... A threaded connection is made to a second steel pipe 15, which also serves as a water flow channel, working in conjunction with a first steel pipe 10 to guide the water flow to the test area. Clips 9 are fixedly connected to the upper and lower ends of the first steel pipe 10 and the pressure relief pipe 14, and to the top of the second steel pipe 15. Clips 9 are used to secure the air pipe 13, ensuring a tight and stable connection. Expansion rubber 11 is fixedly connected to the outer walls of both the first steel pipe 10 and the second steel pipe 15. After expansion, the expansion rubber 11 seals the gap between the pipe and the borehole wall, preventing water leakage and ensuring test accuracy. Multiple clips are used. The device 9 is internally connected to an air pipe 13 and passes through the interior of steel pipe 10 and steel pipe 15. The air pipe 13 is used to transmit air to provide an air source for the expansion of the rubber 11. The top of the air pipe 13 is connected to an air pressure device 12. The air pressure device 12 adjusts the air pressure to control the degree of expansion of the rubber 11. The bottom of the water pump 3 is equipped with a stabilizing mechanism 2. The stabilizing mechanism 2 is used to enhance the stability of the device on various terrains, ensure that the device can work normally under different ground conditions, and avoid the device shaking or displacement due to uneven ground, which would affect the test.

[0033] Specifically, in the engineering geological survey, the inlet pipe 1 serves to transport the water source. Water is introduced into the device through the inlet pipe 1, and the water pump 3 starts working. The water pump 3 is connected to the left side of the inlet pipe 1. Using the high-speed rotation of the impeller, it pressurizes the water flow, giving it an initial pressure boost. The water flow pressurized by the water pump 3 then flows into the booster 4, which is located behind the water pump 3 and connected to it. The booster 4 further increases the water pressure by compressing air, achieving a higher pressure level to meet the high-pressure water flow requirements of the pressure test, ensuring the continuity and stability of the water pressure. The air tank 5 is connected to the left side of the booster 4 and is used to store air. This air is used when the water pressure fluctuates. The air inside air tank 5 acts as a buffer, ensuring a stable output of water pressure and providing a stable high-pressure water flow for the test. After stabilization, the high-pressure water flow continues to be transmitted through high-pressure water pipe 6, which is connected to the left side of air tank 5. This high-pressure water flow, after pressurization and stabilization, is delivered to converter 7. Converter 7 changes the water flow direction, transforming the horizontally transmitted water flow into a downward direction via steel pipe 10. A sealing bolt 8 is connected to the top of steel pipe 10 to prevent leakage, ensuring the water flows in a closed environment throughout the test and preventing leakage from affecting the test results. A pressure relief pipe 14 is threaded to the bottom of steel pipe 10. Pressure relief pipe 14 is used for pressure testing during the test. In this test section, pressure can be released through the pressure relief pipe 14, and pressure changes can be measured to understand the permeability characteristics of the test section. The bottom of the pressure relief pipe 14 is connected to the second steel pipe 15, which also serves as a water flow transmission channel and works in conjunction with the first steel pipe 10. The upper and lower ends of the first steel pipe 10, the pressure relief pipe 14, and the top of the second steel pipe 15 are all fixedly connected to the clamps 9. The clamps 9 are used to fix the air pipe 13, ensuring the tightness and stability of the connection, preventing air leakage, and ensuring smooth air transmission. The air pipe 13 runs through the interior of the first steel pipe 10 and the second steel pipe 15, and is connected to the interior of multiple clamps 9. The function of the air pipe 13 is to transmit air and provide an air source for the expansion of the expanding rubber 11. The top of the air pipe 13 is connected to An air pressure device 12 is provided, which can adjust the air pressure. By controlling the air pressure entering the air pipe 13, the expansion degree of the expansion rubber 11 can be precisely controlled. When the expansion rubber 11 expands, it can tightly seal the gap between the pipe and the borehole wall, preventing water from leaking out of the gap between the pipe and the borehole wall, and ensuring the accuracy of the test. A stabilizing mechanism 2 is provided at the bottom of the water pump 3. The stabilizing mechanism 2 can be adjusted according to different terrains. By adjusting the support leg structure, it can adapt to various uneven ground conditions, enhance the stability of the device on various terrains, ensure that the device can work normally under different ground conditions, and avoid the device shaking or displacement due to uneven ground, thereby affecting the accuracy and reliability of the water pressure test.

[0034] Reference Figure 1 , Figure 2and Figure 4 The stabilizing mechanism 2 includes a base plate 201, the top of which is fixedly connected to the bottom of the water pump 3, providing a stable support base for the water pump 3 and ensuring its stability during operation. Fixing rings 202 are fixedly connected to the four corners of the bottom of the base plate 201. These fixing rings 202 connect to multi-stage telescopic rods 203. The bottoms of the multiple fixing rings 202 are all fixedly connected to the multi-stage telescopic rods 203, whose lengths can be adjusted according to different terrains to adapt to varying ground elevations. A horizontal shaft 204 passes through the bottom of each of the multiple multi-stage telescopic rods 203, providing rotational support for a fixing block 205, allowing the fixing block 205 to rotate flexibly to adapt to different ground shapes. Fixing blocks 205 are rotatably connected to both ends of the multiple horizontal shafts 204, and these fixing blocks 205 are used to install bearings. 206. To ensure a stable connection, bearings 206 are fixedly connected to the outer walls of multiple fixing blocks 205. Bearings 206 allow the fixing blocks 205 to rotate in different ground conditions. Fixing cones 207 are fixedly connected to the bottom of multiple bearings 206. Fixing cones 207 can be inserted into the ground to enhance the connection stability between the device and the ground. Limiting screws 208 are rotatably connected to the top left and right ends of the front side of multiple bearings 206. Limiting screws 208 are used to adjust the angle of fixing cones 207. The rear side of multiple limiting screws 208 passes through the interior of limiters 209 and is threaded to the top left and right ends of the front side of fixing cones 207. Limiters 209, in conjunction with limiting screws 208, limit the rotation angle of fixing cones 207 to ensure that fixing cones 207 work within a suitable angle range.

[0035] Specifically, when the stabilizing mechanism 2 is placed on different surfaces, the base plate 201, as the initial load-bearing component, is connected to the water pump 3. The fixing rings 202 at the four corners at the bottom securely connect the multi-stage telescopic rods 203 to the base plate 201. When the stabilizing mechanism 2 needs to be adjusted, the operator can flexibly adjust the length of the multi-stage telescopic rods 203 at each position according to the actual ground conditions, ensuring that the base plate 201 remains horizontal and providing a stable platform for the operation of the device. The horizontal axis 204 at the bottom of the multi-stage telescopic rods 203 provides a rotating platform for the fixed block 205. As the ground shape changes, the fixed block 205 can rotate freely around the horizontal axis 204. On inclined ground, the fixed block 205 rotates accordingly, causing the components to conform to the ground surface, further enhancing the adaptability of the stabilizing mechanism 2 to complex ground conditions. The bearings 206 on the outer wall of the fixed block 205 optimize the rotation experience of the fixed block 205. As the fixed block 205 rotates following the changes in the ground, the bearing 206 reduces rotational friction to ensure smooth rotation and allows for flexible adjustment of the rotation direction of the fixed block 205. The fixed cone 207, fixed to the bottom of the bearing 206, inserts forcefully into the ground with its sharp shape after the entire mechanism is adjusted. This generates strong friction and gripping force through tight fixation with the ground, effectively reducing displacement and shaking during device operation. The limiting screws 208 connected to the left and right ends of the front top of the bearing 206 work closely with the limiters 209 to limit and stabilize the rotation angle of the fixed cone 207. To adjust the angle at which the fixed cone 207 is inserted into the ground, the operator rotates the limiting screws 208 to move it within the limiters 209, precisely controlling the tilt angle of the fixed cone 207 to ensure stable operation of the device that stabilizes the top of the base plate 201.

[0036] Reference Figure 1 , Figure 2 and Figure 3A support plate 27 is fixedly connected to the bottom of the air pressure unit 12. The support plate 27 supports the air pressure unit 12, enhances its stability, and ensures that the air pressure unit 12 can work normally. Support columns 16 are fixedly connected to the four corners of the bottom of the support plate 27. The support columns 16 support the support plate 27 and the air pressure unit 12 above it, ensuring the stable operation of the air pressure unit 12. A flow meter 19 is connected to the right side of the outer wall of the high-pressure water pipe 6. The flow meter 19 can monitor the flow rate of the water in the high-pressure water pipe 6 in real time, providing the test personnel with water flow data to facilitate the control of the test progress. The bottom of the flow meter 19 is fixedly connected to a fixing column 17. The fixing column 17 is used to stabilize the flow meter 19 and prevent it from shaking under the impact of water flow, so as to ensure the accuracy of the measurement data. The left side of the outer wall of the high-pressure water pipe 6 is connected to a pressure gauge 18. The pressure gauge 18 can intuitively display the pressure value of the water flow in the high-pressure water pipe 6, which helps the test personnel to understand the water flow pressure status and facilitate timely adjustment of the device parameters. The booster 4 is fixedly connected to an inlet valve 26. The inlet valve 26 can control the flow rate and on / off of the water entering the booster 4, which facilitates the adjustment of the working state of the booster 4 and ensures that the water flow can be effectively pressurized.

[0037] Specifically, the water pressurized by the water pump 3 flows into the booster 4 connected to the rear. The booster 4 is equipped with an inlet valve 26. By controlling the inlet valve 26, the flow rate and on / off state of the water entering the booster 4 can be adjusted. The pressurized water flows into the air tank 5, which is connected to the left side of the booster 4. When the water pressure fluctuates, the air inside the tank can act as a buffer to ensure a stable water pressure output. After the pressure stabilizes, the high-pressure water continues to be transmitted through the high-pressure water pipe 6. The right side of the outer wall of the high-pressure water pipe 6 is connected to a flow meter 19, which can monitor the water flow rate in real time and provide flow data for the test personnel. The left side of the outer wall is connected to a pressure gauge 18, which displays the water pressure value intuitively, making it convenient for the test personnel to understand the pressure status and adjust the device parameters in a timely manner. The bottom of the air pressure device 12 is connected to a support plate 27. The support columns 16 at the four corners of the bottom of the support plate 27 jointly support the air pressure device 12 to ensure stable operation.

[0038] Reference Figure 1 , Figure 3 and Figure 4The rear side of the air tank 5 is connected to a pressure dividing pipe 20, which is used to divide the pressure inside the air tank 5. A pressure dividing valve 21 is fixedly connected to the outer wall, which can adjust the pressure inside the pressure dividing pipe 20. A support frame 24 is fixedly connected to the bottom of the water pump 3, which supports the water pump 3. A protective block 25 is fixedly connected to the bottom of the steel pipe 15, which can prevent damage to the bottom of the steel pipe 15. A protective pad 22 is fixedly installed on the front side of the top of the base plate 201, which prevents the control box 23 from being worn. The control box 23 is fixedly connected to the top of the protective pad 22, which is used to control the operation of the entire device.

[0039] Specifically, the air tank 5 plays a role in stabilizing the water flow pressure. The pressure-dividing pipe 20 connected to the rear of the air tank 5 can divert the pressure inside the air tank 5. The pressure-dividing valve 21 connected to the outer wall of the pressure-dividing pipe 20 can flexibly adjust the pressure inside the pressure-dividing pipe 20 according to actual needs, ensuring that the pressure after diversion meets the usage requirements of different stages. The water pump 3 is a component for pressurizing the water flow. The support frame 24 at the bottom supports the water pump 3 to ensure the stability of the water pump 3 during operation and avoid the impact of shaking on the pressurization effect. The steel pipe 15 is responsible for transmitting the water flow. The protective block 25 connected at the bottom effectively prevents the bottom of the steel pipe 15 from being damaged by friction and collision with the ground or other objects during the movement or placement of the device, thus extending its service life. The protective pad 22 set on the front of the top of the base plate 201 can prevent the control box 23 placed on top from being worn. The control box 23 is used to control the device. The operator controls the water pump 3 by starting and stopping, adjusting the pressure of the booster 4, and adjusting the air pressure of the air pressure device 12, ensuring that the entire device can successfully complete the geological exploration task of the water pressure test.

[0040] Working principle: In engineering geological exploration, water enters through inlet pipe 1 and flows to water pump 3. Pump 3 initially pressurizes the water flow. Booster 4 uses compressed air to further pressurize the water flow, meeting the high-pressure requirements of the pressure test and ensuring continuous and stable water pressure. Air tank 5 stores air, which acts as a buffer when water pressure fluctuates, ensuring stable water pressure output. The high-pressure water flow, after stabilization, is transmitted through high-pressure water pipe 6 to converter 7. Converter 7 changes the water flow direction, turning the horizontal flow downwards, flowing into steel pipe 10 with sealing bolts 8 at the top to prevent leakage. Water is used to ensure that the water flows in a closed environment. The bottom of the steel pipe 10 is connected to the pressure relief pipe 14 for pressure testing during the experiment. It can release pressure and measure changes to understand the permeability characteristics of the test section. The bottom of the pressure relief pipe 14 is connected to the steel pipe 2 15. The two work together to transmit water flow. The clamps 9 at the top and bottom of the steel pipe 10, the pressure relief pipe 14 and the top of the steel pipe 2 15 fix the air pipe 13 that runs through the inside to prevent air leakage. The air pipe 13 is connected to the air pressure device 12 at the top. By adjusting the air pressure, the expansion degree of the expansion rubber 11 is controlled to seal the gap between the pipe and the borehole wall and ensure the accuracy of the test.

[0041] When the position of the stabilizing mechanism 2 needs to be adjusted, the operator adjusts the length of the multi-stage telescopic rod 203 according to the ground conditions to keep the base plate 201 level, providing a stable foundation for the operation of the device. The horizontal axis 204 at the bottom of the multi-stage telescopic rod 203 allows the fixed block 205 to rotate freely. On inclined or complex ground, the fixed block 205 rotates around the horizontal axis 204, causing the device to conform to the ground and enhancing adaptability. The bearing 206 on the outer wall of the fixed block 205 reduces rotational friction, ensuring smooth rotation of the fixed block 205 and allowing for adjustment of the rotation direction at any time. After the device is adjusted, the fixed cone 207, with its sharp shape, inserts into the ground, generating strong friction and gripping force, reducing device displacement and shaking. When it is necessary to adjust the angle at which the fixed cone 207 is inserted into the ground, the operator rotates the limit screw 208 to move it within the limiter 209, precisely controlling the tilt angle of the fixed cone 207 to ensure the stability of the device. This allows the stabilizing mechanism 2 to play a stable supporting role, ensuring that the components above the base plate 201 can operate stably and smoothly.
