Description

Technical Field

[0001] The present application relates to the technical field of engineering geological survey, and in particular to a water pressure testing device for engineering geological survey. Background Art

[0002] The water pressure test is a test that uses a water pump or the weight of a water column to pressurize clean water into the test section of the borehole. Based on the relationship between the amount of water pressed in a certain period of time and the amount of pressure applied, the relative permeability of the rock mass and the degree of fracture development are calculated. When conducting a water pressure test, a water pressure test device is required.

[0003] Chinese patent CN218865723U discloses a device for water pressure test in engineering geological survey, including a load-bearing plate and a water pressure tank, wherein a universal wheel is movably mounted on the bottom of the load-bearing plate, a placement sleeve is fixedly connected to the top of the load-bearing plate, a lifting device is placed outside the placement sleeve, and the lifting device includes a protection box fixedly connected to the right side of the placement sleeve, a threaded rod is movably connected inside the protection box, and a rotating rod is threadedly connected outside the threaded rod.

[0004] In the above patent, the water gun is vertically facing the ground, and there is no adjustment for the angle of the water gun. When the angle of the borehole is not vertical (for example, when building a tunnel, in order to find out the engineering geological conditions of the tunnel, it is necessary to conduct drilling exploration on both sides of the tunnel), the borehole cannot be tested for water pressure, which reduces the practicality of the device. Therefore, a technical measure is proposed to solve the problem of lack of adjustment for the angle of the water gun. When the angle of the borehole is not vertical, the borehole cannot be tested for water pressure, which reduces the practicality of the device. Utility Model Content

[0025] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0026] Reference Figure 1 and Figure 2 As shown, the workbench 1 comprises a workbench 1 and a lifting assembly 2. A water tank 5 is installed on the upper surface of the workbench 1. A water pump 10 is installed on the upper surface of the water tank 5. The water pump 10 is connected to the water tank 5. A water pressure gauge 8 and a water flow meter 9 are installed on the water pump 10. A column 12 is installed at one end of the workbench 1 away from the water tank 5. A rotating assembly 3 is installed on the upper part of the column 12. A plurality of moving wheels 6 are installed on the lower surface of the workbench 1. A push handle 4 is installed at one end of the workbench 1 away from the column 12. A water inlet is provided on the upper part of the water tank 5. The lifting assembly 2 comprises a connecting block 202, the connecting block 202 is connected to the rotating assembly 3, the side of the connecting block 202 is connected to the box body 201, the upper part of the box body 201 is threaded with a screw 207, the upper end of the screw 207 is connected to a turntable 208, the lower end of the screw 207 is rotatably connected to a connecting plate 206, the lower part of the connecting plate 206 is connected to a water gun 205, and the side of the water gun 205 is equipped with a connecting pipe 204, The connecting pipe 204 is fixedly connected to the hose 11, and a limiting groove 203 is provided on the side of the box body 201. The connecting pipe 204 is adapted to the limiting groove 203. When the water pressure test is actually performed on the borehole, water is injected into the water tank 5 through the water inlet pipe 7, and the device is pushed to the borehole through the push handle 4. The angle of the water gun 205 is adjusted using the rotating component 3 according to the angle of the borehole, and then the water gun 205 is clamped into the borehole through the lifting component 2. Specifically, the turntable 208 is rotated, and the turntable 208 is pressed. The rotation drives the screw 207 to rotate, and the rotation of the screw 207 pushes the connecting plate 206 to move. When the connecting plate 206 moves, it drives the water gun 205 to enter the borehole. When the water gun 205 enters the borehole, it drives the connecting pipe 204 to slide along the limiting groove 203. When the water gun 205 is stuck in the borehole at an appropriate distance, the rotation of the turntable 208 is stopped, and then the water pump 10 is started. The water pump 10 starts to draw water from the water tank 5 into the hose 11, and then the water flows into the water gun 205 and finally enters the borehole.

[0027] Reference Figure 1 , Figure 3 and Figure 4As shown, the rotating assembly 3 includes a mounting block 301, which is fixedly mounted on the upper part of the column 12, a slide groove 302 is provided on the upper surface of the mounting block 301, a rotating rod 303 is rotatably connected in the mounting block 301, a clamping groove 309 is provided in the middle position of the rotating rod 303, the rotating rod 303 is fixedly connected to the connecting block 202, a pull plate 307 is slidably connected to the slide groove 302, a round rod 304 is installed at one end of the pull plate 307 facing the rotating rod 303, a clamping plate 305 is connected to the round rod 304, the clamping plate 305 is arranged in an arc shape, the clamping plate 305 is provided with a clamping tooth 306, a spring 308 is installed at one end of the pull plate 307 away from the round rod 304, and the spring 308 is installed at the other end of the pull plate 307 away from the round rod 304. 08 The other end is installed inside the mounting block 301, and the slot 309 is matched with the tooth 306. The pull plate 307 is pulled in the direction close to the push handle 4. The pull plate 307 moves and drives the round rod 304 to move. When the pull plate 307 moves, the spring 308 is compressed. The round rod 304 moves and drives the card plate 305 to move. The card plate 305 moves and drives the tooth 306 to disengage from the slot 309, releasing the limit on the rotating rod 303. At this time, the lifting component 2 is rotated, and the lifting component 2 rotates and drives the water gun 205 to rotate. When the angle of the water gun 205 is matched with the angle of the drilling hole, the pull plate 307 is released, and the tooth 306 clamps the slot 309 under the rebound action of the spring 308.

[0028] Working principle: When the borehole is actually subjected to a water pressure test, water is injected into the water tank 5 through the water inlet pipe 7, the device is pushed to the borehole through the push handle 4, and the angle of the water gun 205 is adjusted according to the angle of the borehole. Specifically, the pull plate 307 is pulled in the direction close to the push handle 4, and the pull plate 307 moves to drive the round rod 304 to move. When the pull plate 307 moves, the spring 308 is compressed, and the round rod 304 moves to drive the card plate 305 to move, and the card plate 305 moves to drive the card tooth 306 to disengage from the card slot 309, thereby releasing the limit on the rotating rod 303. At this time, the lifting assembly 2 is rotated, and the lifting assembly 2 rotates to drive the water gun 205 to rotate. When the angle of the water gun 205 matches the angle of the borehole , release the pull plate 307, and the latch tooth 306 clamps the clamping slot 309 under the rebound action of the spring 308 (the clamping slot 309 and the latch tooth 306 can be arranged more closely to ensure that the latch tooth 306 is clamped into the clamping slot 309, and when the latch tooth 306 and the clamping slot 309 are more closely, when the latch tooth 306 is adjusted to clamp into the clamping slot 309, the angle movement of the water gun 205 is very small, and will not affect the next step of the water gun 205 being clamped into the drill hole). Through the setting of the rotating component 3, it is convenient to flexibly adjust the angle of the water gun 205 according to the angle of the drill hole, so that the water gun 205 can be clamped into the drill hole, which is convenient for the next step of the water pressure test, thereby improving the practicality of the device;

[0029] Then, the water gun 205 is inserted into the borehole through the lifting component 2. Specifically, the turntable 208 is rotated, and the rotation of the turntable 208 drives the screw 207 to rotate. The rotation of the screw 207 drives the connecting plate 206 to move. When the connecting plate 206 moves, it drives the water gun 205 to enter the borehole. When the water gun 205 enters the borehole, it drives the connecting pipe 204 to slide along the limiting groove 203. When the water gun 205 is inserted into the borehole at an appropriate distance, the rotation of the turntable 208 is stopped, and then the water pump 10 is started (the water pump 10 can be powered by connecting a long electric wire to observe the water flow and water pressure through the water pressure gauge 8 and the water flow meter 9). When the water pump 10 is started, water is pumped from the water tank 5 into the hose 11, and then the water flows into the water gun 205, and finally enters the borehole. The setting of the lifting component 2 facilitates the lifting and lowering adjustment of the water gun 205.
