Description

Technical Field

[0001] This utility model relates to the field of drilling and water injection testing technology for seepage-proof walls, and more specifically, to a seepage-proof wall drilling and water injection testing device that prevents deviation. Background Technology

[0002] In the construction of concrete cut-off walls, water injection testing is a crucial step in evaluating seepage prevention performance. Existing water injection testing equipment typically employs a fixed structure, where the equipment is installed in the test borehole for water injection. However, this existing equipment has the following shortcomings in practical applications: Most existing equipment uses a rigid structure, resulting in a large overall size that is difficult to adapt to changes in test borehole size. Installation and disassembly require additional tools or complex procedures, leading to long preparation times and low work efficiency. Furthermore, because the diameter of the test borehole may vary, existing equipment cannot flexibly adjust its dimensions to accommodate different borehole sizes. Test holes may lead to insufficient sealing between the equipment and the test holes, affecting the accuracy of test data. Since water injection tests on the seepage barrier are usually conducted outdoors, the existing equipment may be affected by external forces (such as wind, water flow, mechanical vibration, etc.) after installation, causing it to shift. In liquid level measurement, scale deviation will cause the read liquid level height to be inconsistent with the actual height, which in turn may cause the rise and fall height of the float to be inconsistent with the actual water level change, affecting the reliability of test data. Furthermore, if the equipment shifts, the float will generate greater friction with other components, which will further affect the reliability of test data. Utility Model Content

[0003] The purpose of this invention is to provide a test device for drilling and injecting water into a seepage-proof wall to prevent deviation, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, a water injection test device for a seepage-proof wall borehole with anti-deviation capability is provided. The device includes a frame assembly, through which water is injected from the top of the frame assembly and stored between the frame assembly and the test hole wall, permeating into the sidewall of the test hole. A float plate is slidably disposed inside the frame assembly, floating on the water surface. A scale is fixedly connected above the float plate, its surface engraved with graduations. The float plate supports the scale, and its position is adjusted by the rise and fall of the water level, causing the portion of the float plate exposed above the top of the frame assembly to change. A fixing component is disposed inside the frame assembly above the float plate, vertically positioned on the axis of the frame assembly. The frame assembly can be folded or unfolded internally. The fixing component automatically unfolds in the normal state. Pulling the fixing component upwards causes it to fold. The folded fixing component slides in the test hole. The unfolded fixing component presses against the inner wall of the test hole, fixing the fixing component in the test hole and driving the frame assembly to be fixed in the test hole. A sealing component is provided below the float plate. The sealing component is coaxially arranged with the fixing component and cooperates with the frame assembly to keep the scale vertical. The sealing component is located at the bottom of the frame assembly. Rotating the fixing component causes the sealing component to slide upwards and press against the bottom of the frame assembly, deforming the sealing component and pressing against the side wall of the test hole.

[0005] The frame assembly includes a fixed cover that is snapped onto the ground. The top of the fixed cover has a water injection hole and a limiting hole. A scale slides through the limiting hole. Several grooved rods are fixedly connected to the bottom of the fixed cover. A base plate is fixedly connected to the bottom of the grooved rods. A float is disposed between the fixed cover and the base plate and slides up and down. Several sliders are provided on the side wall of the float. A sliding groove is provided on the inner side of several grooved rods. The sliders slide in the sliding grooves so that the float remains vertical when sliding.

[0006] The fixing assembly includes a pull rod that passes through the fixing cover. A fixing triangular plate is rotatably sleeved on the pull rod. The top of the fixing triangular plate is fixedly connected to the bottom of the fixing cover. A hinge rod is hinged to the bottom of the fixing triangular plate. A connector is hinged to the bottom of the hinge rod. The hinge rod is hinged to the middle section of the connector. An L-shaped rod is hinged to the end of the connector near the pull rod. The top of the L-shaped rod is hinged to the bottom of the fixing triangular plate near the pull rod. A movable groove is formed on the upper side of the L-shaped rod away from the hinge rod. A movable triangular plate is slidably disposed below the fixing triangular plate. The lower side of the movable triangular plate is engaged in the movable groove. The movable triangular plate slides up and down, driving several L-shaped rods to swing through the movable groove. The swinging L-shaped rods push the connector to slide horizontally, causing the connector to unfold or fold relative to the pull rod.

[0007] The end of the connector away from the pull rod is thicker than the other end. A pressure plate is fixedly installed on the end of the connector away from the pull rod. A rubber plate is fixedly installed on the side of the pressure plate away from the connector. The rubber plate is in close contact with the side wall of the test hole.

[0008] A spring is provided between the fixed triangle plate and the movable triangle plate. The spring keeps the fixed triangle plate and the movable triangle plate away from each other. Under normal conditions, the movable triangle plate presses downward against the inner wall of the movable groove, and several rubber plates continuously press against the side wall of the test hole under normal conditions. Pulling the pull rod upward compresses the spring and drives the movable triangle plate to slide upward, so that the several rubber plates move away from the side wall of the test hole.

[0009] The lower end of the pull rod is fixedly connected to a first spline rod, and the top of the first spline rod is fixedly connected to a friction ring. A friction sleeve is rotatably fitted around the friction ring. The top surface of the friction sleeve contacts the bottom surface of the movable triangular plate. The spring presses the movable triangular plate downward, so that the movable triangular plate is in close contact with the friction sleeve. The friction sleeve prevents the friction ring from rotating without external force.

[0010] The lower end of the first spline rod is slidably fitted with a spline groove sleeve. The sealing assembly includes a second spline rod slidably inserted into the lower end of the spline groove sleeve. The first spline rod and the second spline rod are connected in a non-contact manner through the spline groove sleeve. When the pull rod rotates, it drives the second spline rod to rotate through the first spline rod and the spline groove sleeve. When the pull rod slides upward, it slides inside the spline groove sleeve and continues to maintain connection with the second spline rod.

[0011] A screw is fixedly connected to the lower part of the second spline rod, and an isolation ring is fixedly sleeved on the top of the screw. The isolation ring is in rotatable contact with the bottom of the spline groove sleeve. The isolation ring drives the spline groove sleeve to slide upward, and makes the spline groove sleeve continue to be sleeved on the outside of the first spline rod and the second spline rod.

[0012] The lower end of the screw is connected to a rubber plug via a thread. The rubber plug is located below the base plate and contacts the bottom of the base plate. The rotating splined sleeve drives the screw to rotate via the second splined rod. The rotating screw drives the rubber plug to slide upward via the thread. The upward sliding rubber plug and the base plate are pressed against each other, and the outer ring of the rubber plug is deformed. The deformed rubber plug presses against the side wall of the test hole, sealing the test hole from the bottom. The deformed rubber plug fixes the bottom of the device in the test hole, and together with the several rubber plates above, it fixes the device vertically in the test hole.

[0013] A retaining ring is rotatably fitted at the bottom of the screw. The retaining ring is located below the rubber plug. When the pull rod rotates, the retaining ring limits the rubber plug and prevents the rubber plug from separating from the base plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. In this anti-deviation seepage-proof wall drilling and water injection test equipment, the rotating pull rod drives the splined sliding sleeve to rotate, and the splined sliding sleeve transmits power to the second splined rod, causing the screw to drive the rubber plug upward to press against the base plate. This causes the rubber plug to undergo elastic deformation, automatically filling the gap at the bottom of the test hole, enhancing the overall stability of the equipment in the test hole. This self-adaptability allows the equipment to quickly adapt to test holes of different diameters and shapes, improving the equipment's versatility and flexibility. The elastic deformation of the rubber plug not only serves as a seal but also, through cooperation with several rubber plates and fixed covers above, forms a sturdy cylindrical shape that is vertically fixed in the test hole, reducing the influence of external forces. This ensures that the equipment will not deviate due to external forces during the water injection test, keeping the scale plate always vertical. This avoids discrepancies between the read liquid level and the actual height due to scale deviation, improving the accuracy and reliability of the test data.

[0016] 2. In this anti-deviation seepage wall drilling and water injection test equipment, by releasing the pull rod, the elastic force of the spring can automatically push the movable triangular plate downward, causing the L-shaped rod to swing and push the connecting piece to slide horizontally, thereby enabling the equipment to quickly unfold and be fixed in the test hole. This process does not require complicated tools or manual adjustment, which significantly improves the installation efficiency. When disassembling, simply pull the pull rod upward, and the equipment can be quickly folded and easily removed from the test hole, greatly shortening the test preparation and end time.

[0033] Example 1

[0034] Please see Figures 1-9As shown, the purpose of this embodiment is to provide a seepage prevention wall drilling and water injection test device, including a frame assembly 1. Water is injected from the top of the frame assembly 1 and stored between the frame assembly 1 and the test hole wall, and permeates into the side wall of the test hole. This structural design allows the device to simulate the seepage environment under actual working conditions, providing a basic condition for seepage performance testing. It has the advantages of simple operation and realistic simulation. A float 5 is slidably installed inside the frame assembly 1. The float 5 floats on the water surface. This design can automatically adjust the position of the float 5 according to the water level change, thereby realizing real-time monitoring of water level changes. It has the advantages of strong automatic adaptability and high measurement accuracy. A scale 6 is fixedly connected above the float 5. The surface of the scale 6 is engraved with graduations. The float 5 supports the scale 6. The rise and fall of the water level drives the float 5 to rise and fall, so that the part of the float 5 exposed above the top of the frame assembly 1 changes. This structure can intuitively show the changes in the water level. The water level changes are read by scale, providing accurate data support for the experiment. It has the advantages of intuitive measurement and convenient data acquisition. The frame component 1 is equipped with a fixing component 2 located above the float 5. The fixing component 2 is vertically set on the axis of the frame component 1. The fixing component 2 can be folded or unfolded inside the frame component 1. The fixing component 2 unfolds automatically in the normal state. Pulling the fixing component 2 upward will fold it, allowing the fixing component 2 to flexibly adjust its shape in the test hole, which is convenient for the installation and fixation of the equipment. It has the characteristics of flexible operation and strong adaptability. The folded fixing component 2 slides in the test hole. The unfolded fixing component 2 presses against the inner wall of the test hole, fixing the fixing component 2 in the test hole and driving the frame component 1 to be fixed in the test hole. This structure can ensure the stability and reliability of the equipment during the test, avoiding the impact of the test results due to the loosening of the equipment. It has the advantages of firm fixation and stable test.

[0035] A sealing component 3 is installed below the float plate 5. The sealing component 3 expands radially under pressure, adaptively filling the cracks in the hole wall to form a dynamic seal. The sealing component 3 is coaxially arranged with the fixing component 2 and cooperates with the frame component 1 to keep the scale 6 vertical. Since the liquid level measurement is designed based on the vertical state of the scale 6, keeping the scale 6 vertical can ensure that the equipment operates normally according to the design principle, and at the same time ensure that the related moving parts move smoothly without obstruction, avoiding problems such as jamming or excessive friction, thereby improving the reliability of the test data. The sealing component 3 is located at the bottom of the frame component 1. The sealing component 3 blocks the water flow from below. Rotating the fixing component 2 causes the sealing component 3 to slide upward and squeeze the bottom of the frame component 1, causing the sealing component 3 to deform and squeeze the side wall of the test hole. This structure can further enhance the sealing between the equipment and the test hole, prevent water leakage, and ensure the accuracy of the test data. It has the advantages of good sealing performance and high test accuracy.

[0036] The frame assembly 1 includes a fixed cover 11, which is secured to the ground to ensure the stability of the equipment during testing and prevent displacement due to external forces or water flow impact, thereby ensuring the accuracy of the test. The top of the fixed cover 11 has a water injection hole and a limiting hole. A scale 6 slides through the limiting hole. The water injection hole is used to inject test water into the equipment, and the limiting hole guides the sliding of the scale 6. This design allows the water injection and measuring equipment to be integrated into the same structure, simplifying the overall design of the equipment while ensuring the stability of the scale 6 during sliding. Several grooved rods 12 are fixedly connected to the bottom of the fixed cover 11. The bottom of the 12 is fixedly connected to the base plate 13, thus forming a layered structure. This design not only increases the overall strength of the equipment, but also provides a stable support platform for the internal components, enabling the various components to work together better. The float 5 is set between the fixed cover 11 and the base plate 13 and slides up and down. The side wall of the float 5 is provided with several sliders, and the inner side of several groove rods 12 is provided with a sliding groove. The sliders slide in the sliding groove, so that the float 5 remains vertical when sliding. This structural design can effectively prevent the float 5 from tilting or shifting during the sliding process, ensuring the stability of its movement, thereby improving the accuracy of the test data.

[0037] The fixing component 2 includes a pull rod 21 that passes through the fixing cover 11. A fixing triangular plate 23 is rotatably sleeved on the pull rod 21. The top of the fixing triangular plate 23 is fixedly connected to the bottom of the fixing cover 11, allowing the fixing triangular plate 23 to rotate around the pull rod 21 while fixing the rest of the structure to the fixing cover 11, providing stable support for subsequent unfolding and folding operations. A hinge rod 26 is hinged to the bottom of the fixing triangular plate 23, and a connector 27 is hinged to the bottom of the hinge rod 26. The hinge rod 26 is hinged to the middle section of the connector 27. This multi-stage hinge structure allows the hinge rod 26 and the connector 27 to flexibly adjust their angles and positions, providing the necessary space for the unfolding and folding operations of the fixing component 2. An L-shaped rod 25 is hinged to the end of the connector 27 near the pull rod 21. The top of the L-shaped rod 25 is hinged to the bottom of the fixing triangular plate 23 near the pull rod 21. On the side near the pull rod 21, the L-shaped rod 25 can transmit force and movement between the fixed triangle plate 23 and the connector 27, serving as a connection and transmission mechanism. The upper end of the L-shaped rod 25 away from the hinge rod 26 has a movable groove. A movable triangle plate 24 is slidably arranged below the fixed triangle plate 23. The lower side of the movable triangle plate 24 is engaged in the movable groove, allowing the sliding of the movable triangle plate 24 to drive the L-shaped rod 25 to swing through the movable groove, thereby realizing the transmission of force and the conversion of motion. The movable triangle plate 24 slides up and down, driving several L-shaped rods 25 to swing through the movable groove. The swinging L-shaped rods 25 push the connector 27 to slide horizontally, causing the connector 27 to unfold or fold relative to the pull rod 21. This linkage structure realizes the flexible unfolding and folding function of the fixed component 2, providing convenience for the installation and fixation of the equipment in the test hole.

[0038] The end of connector 27 furthest from pull rod 21 is thicker than the other end. This design increases the strength and stability of this end, while providing a larger contact area for the connection of subsequent components. It can better withstand lateral forces and pressures during deployment, ensuring the overall structural robustness. A pressure plate 29 is fixedly installed on the end of connector 27 furthest from pull rod 21. The larger connection area enhances the stability of pressure plate 29. This design allows pressure plate 29 to remain stable when subjected to external forces, avoiding structural deformation or damage caused by local stress concentration, thereby improving the overall reliability of the equipment. A rubber plate 28 is fixedly installed on the side of pressure plate 29 furthest from connector 27. The rubber plate 28 is in close contact with the sidewall of the test hole. By increasing the contact area and friction, the equipment can be firmly fixed in the test hole, preventing loosening or displacement due to water flow impact or external forces, ensuring the stability of the equipment during the test.

[0039] A spring is installed between the fixed triangular plate 23 and the movable triangular plate 24. The elastic force of the spring keeps the fixed triangular plate 23 and the movable triangular plate 24 away from each other. This keeps the movable triangular plate 24 pressing downward against the inner wall of the movable groove under normal conditions, causing several rubber plates 28 to continuously press against the side wall of the test hole under normal conditions. Due to the action of the spring, the movable triangular plate 24 presses downward against the inner wall of the movable groove under normal conditions. Furthermore, through the linkage of the L-shaped rod 25 and the connecting piece 27, several rubber plates 28 continuously press against the side wall of the test hole. This design utilizes a spring. The elastic force ensures that the rubber plate 28 remains in close contact with the side wall of the test hole, thereby increasing friction and firmly fixing the equipment in the test hole to prevent loosening or displacement. Pulling the pull rod 21 upward compresses the spring and causes the movable triangular plate 24 to slide upward, moving the rubber plate 28 away from the side wall of the test hole, thereby releasing the close contact between the equipment and the side wall of the test hole. This design allows the equipment to quickly switch from a fixed state to a movable state when needed, facilitating the installation and disassembly of the equipment and realizing the flexibility and convenience of the equipment during the installation process. At the same time, it ensures that the equipment can be firmly fixed in the working state to meet the test requirements.

[0040] The lower end of the pull rod 21 is fixedly connected to the first spline rod 22, and the top of the first spline rod 22 is fixedly connected to the friction ring 211. The friction ring 211 is rotatably sleeved on the outside of the friction sleeve 221. The top surface of the friction sleeve 221 contacts the bottom surface of the movable triangular plate 24, so that the friction sleeve 221 can rotate freely outside the friction ring 211. At the same time, through the contact with the movable triangular plate 24, the elastic force of the spring is transmitted to the friction sleeve 221, forming a stable force transmission path. The spring presses the movable triangular plate 24 downward, so that the movable triangular plate 24 and the friction sleeve 221 are in close contact. The friction sleeve 221 prevents the friction ring 211 from rotating without external force. The elastic force of the spring ensures that the movable triangular plate 24 and the friction sleeve 221 always maintain a stable contact state, preventing equipment failure due to poor contact caused by external force or vibration.

[0041] The lower end of the first spline rod 22 is slidably fitted with a spline groove sleeve 4. This sliding sleeve structure allows the first spline rod 22 to slide up and down within the spline groove sleeve 4 while maintaining the mechanical connection between the two, providing a flexible connection method for the motion transmission of the equipment. The sealing assembly 3 includes a second spline rod 32 slidably inserted into the lower end of the spline groove sleeve 4. The first spline rod 22 and the second spline rod 32 are connected non-contactly through the spline groove sleeve 4. This design provides redundant space for subsequent transmission while ensuring the smoothness and reliability of motion transmission. When the pull rod 21 rotates, it drives the second spline rod 32 to rotate through the first spline rod 22 and the spline groove sleeve 4. This transmission path design enables the rotational motion of the pull rod 21 to be effectively transmitted to the second spline rod 32, realizing the linkage function of the equipment. When the pull rod 21 slides upward, it slides inside the spline groove sleeve 4 and continues to maintain the connection with the second spline rod 32.

[0042] A screw 31 is fixedly connected to the lower part of the second spline rod 32. An isolation ring 33 is fixedly sleeved on the top of the screw 31. The isolation ring 33 rotates in contact with the bottom of the spline groove sleeve 4, allowing the isolation ring 33 to rotate freely at the bottom of the spline groove sleeve 4. At the same time, motion is transmitted through rotational contact. This rotational contact method not only reduces friction during movement but also ensures the flexibility and reliability of motion transmission, avoiding jamming or wear caused by direct contact. The isolation ring 33 drives the spline groove sleeve 4 to slide upward, and the spline groove sleeve 4 continues to be sleeved outside the first spline rod 22 and the second spline rod 32. This ensures that the spline groove sleeve 4 always maintains a connection with the first spline rod 22 and the second spline rod 32 during the sliding process. This structure not only ensures the integrity of the equipment during movement but also realizes the dynamic adjustment and motion transmission of the equipment through the sliding function of the spline groove sleeve 4, enabling the equipment to maintain a stable operating state under complex operating conditions.

[0043] The lower end of the screw 31 is threadedly connected to a rubber plug 34. The rubber plug 34 is positioned below the base plate 13 and contacts the bottom of the base plate 13, allowing the rubber plug 34 to apply force to the base plate 13 from the bottom, thereby affecting the sealing performance between the entire device and the test hole. Through this contact method, the device can achieve a sealing function by deforming the rubber plug 34 when needed. The rotating splined sleeve 4 drives the screw 31 to rotate through the second splined rod 32. The rotating screw 31 drives the rubber plug 34 to slide upward through the thread. The upwardly sliding rubber plug 34 is pressed against the base plate 13, causing the outer ring of the rubber plug 34 to deform. Utilizing the elastic deformation characteristics of the rubber plug 34, it can adapt to the shape of the test hole, thereby achieving a sealing function. Through this compression and deformation mechanism, the device... The device can form a reliable seal at the bottom of the test hole to prevent water leakage. The deformed rubber plug 34 squeezes the side wall of the test hole to seal it from the bottom. This sealing mechanism not only effectively prevents water leakage from the bottom of the test hole, but also enhances the overall sealing performance of the device during the test. The deformed rubber plug 34 fixes the bottom of the device in the test hole and, together with several rubber plates 28 above, fixes the device vertically in the test hole, thereby preventing the device from shifting due to external forces during the test. If the device shifts, the measurement value may be inaccurate, affecting the test results. At the same time, keeping the device vertical ensures that the relevant moving parts move smoothly and without obstruction during the process, avoiding problems such as jamming or excessive friction, thereby further ensuring the accuracy of the test data.

[0044] A retaining ring 35 is rotatably fitted at the bottom of the screw 31. The retaining ring 35 is located below the rubber plug 34. When the pull rod 21 rotates, the retaining ring 35 limits the rubber plug 34, preventing the rubber plug 34 from separating from the base plate 13. This limiting mechanism ensures close contact between the rubber plug 34 and the base plate 13 through mechanical constraints, maintaining the stability and sealing of the overall structure even during dynamic adjustments of the equipment.

[0045] In practical use, pulling the pull rod 21 upward compresses the spring between the fixed triangular plate 23 and the movable triangular plate 24, causing the movable triangular plate 24 to slide upward. This causes the L-shaped rod 25 to swing through the movable groove, pushing the connector 27 to slide horizontally. This folds the connector 27 relative to the pull rod 21, reducing the overall size of the device and making it easier to insert into the test hole. The folded device is then slowly placed into the test hole, ensuring that it is inserted perpendicularly along the axis of the test hole to avoid tilting or jamming. Releasing the pull rod 21 restores the spring's elasticity, pushing the movable triangular plate 24 downward to press against the inner wall of the movable groove. This causes the L-shaped rod 25 to swing and push the connector 27 to slide horizontally, thus unfolding the connector 27 relative to the pull rod 21. The unfolded rubber plate 28 makes close contact with the side wall of the test hole, increasing friction and fixing the device in the test hole. Rotating the pull rod 21 causes the first spline rod 22 and the spline groove to slide... The sleeve 4 drives the second spline rod 32 to rotate, which in turn drives the screw 31 to rotate. The rotating screw 31 drives the rubber plug 34 to slide upward through the threaded connection, causing the rubber plug 34 to press against the base plate 13. The outer ring of the rubber plug 34 deforms, pressing against the side wall of the test hole to achieve a seal from the bottom. Through its cooperation with several rubber plates 28 above, the device is vertically installed in the test hole, thus keeping the scale 6 vertical with the test hole and ensuring the reliability of the test data. Test water is injected into the device through the water injection hole at the top of the fixed cover 11, and the scale change of the scale 6 is observed and the initial water level is recorded. The water level change is read according to the scale of the scale 6 to analyze the permeability performance of the concrete anti-seepage wall. Pulling the pull rod 21 upward causes the device to fold, releasing the contact between the rubber plate 28 and the side wall of the test hole and the sealing effect of the rubber plug 34, and the device is removed from the test hole.
