Description

Technical Field

[0001] The present invention relates to the technical field of vertical permeameters, and particularly to a vertical permeameter for geotechnical tests. Background Art

[0002] In geotechnical tests, it is a particularly important step to test the permeability of geosynthetics. Geosynthetics is the general term for synthetic materials used in civil engineering. As a civil engineering material, it is made of artificially synthesized polymers (such as plastics, chemical fibers, synthetic rubbers, etc.) into various types of products and placed inside, on the surface of the soil or between various soils to play the role of strengthening or protecting the soil. As a new type of geotechnical engineering material, geosynthetics is known as the "fourth major building material" after the three major building materials of steel, cement, and wood in the world. With the development of China's infrastructure construction, its application is becoming more and more extensive. For example, the permeability of geotextiles or drainage boards directly affects the quality of construction projects. Most of the existing testing methods are to conduct permeability tests on materials through vertical permeameters;

[0003] In the production or use of existing geosynthetics, it is extremely easy for the surface or inside to be contaminated or mixed with some dust, mud, or other sundries. After the water penetrates and dilutes the geosynthetics, these dust and mud often drain out. After multiple tests, the remaining dust, mud, and other sundries accumulate in the test tube for storing the test samples, seriously affecting the accuracy of subsequent tests. Therefore, we propose a vertical permeameter for geotechnical tests. Summary of the Invention

[0022] 1.

[0023] 2. The present invention is provided with a pigging device. The moving sponge sleeve plate cleans the inner wall of the transparent test tube and absorbs the undrained water, preventing sundries such as residual dust and mud from accumulating in the test tube for storing test samples after multiple tests, which seriously affects the accuracy of subsequent tests. The bottom baffle squeezes and drains the sponge sleeve plate from the bottom of the sponge sleeve plate and discharges the absorbed residual water, preventing the sponge sleeve plate from being in a wet state after absorbing the residual water each time, making it difficult to effectively remove sundries such as dust on the surface. By opening a plurality of liquid discharge round holes, it is convenient for the water between the sponge sleeve plate and the bottom baffle to be fully discharged, preventing a large amount of squeezed-out water from still adhering to the top surface of the bottom baffle and being absorbed by the sponge sleeve plate again. When the corrugated connecting piece extends and contracts, it always wraps and covers the connection part of the driving shaft at the bottom of the bidirectional electric telescopic rod, preventing the liquid discharged from the sponge sleeve plate from overflowing at the connection part of the driving shaft at the bottom of the bidirectional electric telescopic rod and seeping into the interior to affect its use.

[0024] 3. The present invention is provided with a cleaning mechanism. The rotating built-in brush rubs and cleans the outer side of the sponge sleeve plate, preventing excessive dust and other sundries from being mixed in the sponge small holes of the sponge sleeve plate after it has cleaned the inner wall of the transparent test tube for a long time and is difficult to remove. By setting an inclined surface concave shell at the bottom of the annular thick plate, it is convenient to store the cleaned dust and the squeezed-out liquid, preventing the cleaned dust and the squeezed-out liquid from the sponge sleeve plate from falling down into the transparent test tube and being difficult to handle. The corrugated ring piece arranged inside the inclined surface concave shell covers most of the area at the bottom of the sponge sleeve plate and facilitates the passing of the sponge sleeve plate, preventing the cleaned dust and the squeezed-out liquid from the sponge sleeve plate from failing to fall smoothly into the inclined surface concave shell for storage. The bidirectional electric telescopic rod can drive the annular sleeve plate to move down to the top of the transparent test tube and block its top, preventing some sundries from entering the transparent test tube during the test and affecting the test effect due to the influence of the external environment.

[0025] 4. The present invention is provided with a drainage device. By setting a circular inclined platform, the liquid discharged after multiple tests is collected and stored, preventing the need for staff to pour out the experimental water after each test, which increases labor and reduces the test efficiency. By opening a first arc hole and a second arc hole, the liquid in the circular inclined platform is stored and discharged, preventing the liquid on the circular inclined platform from accumulating to a certain height and contacting the transparent test tube and gradually seeping into the transparent test tube to affect the test data. The rotating curved scraping rod scrapes and cleans the inner side of the first ring plate and the inclined surface of the circular inclined platform, preventing the inner side of the first ring plate and the inclined surface of the circular inclined platform from still having residual undrained liquid or dust and other sundries. The arc-shaped thorns intermittently pierce into the first arc hole as the curved scraping rod rotates, preventing the liquid and dust and other sundries on the circular inclined platform from blocking the first arc hole during long-term accumulation and storage.

[0051] A plurality of liquid discharge round holes 506 are provided, and the plurality of liquid discharge round holes 506 are evenly distributed at the bottom of the bottom baffle 505. The top of the corrugated connecting piece 507 is fixedly connected to the output end at the bottom of the bidirectional electric telescopic rod 503;

[0052] The cleaning mechanism 504 includes an annular sleeve plate 5041 and a small sleeve plate 5042. An arc-shaped long rod 5043 is fixedly connected to the outer side of the small sleeve plate 5042. One end of the arc-shaped long rod 5043 away from the small sleeve plate 5042 is fixedly connected to an annular thick plate 5044. An internal brush 5045 is fixedly connected to the inner side of the annular thick plate 5044. A connecting block 5046 is fixedly connected to the bottom of the annular thick plate 5044.

The small sleeve plate 5042 is sleeved on the drive shaft at the top of the bidirectional electric telescopic rod 503 and is rotatably connected to the drive shaft at the top of the bidirectional electric telescopic rod 503 through a bearing. A plurality of internal brushes 5045 are provided, and the plurality of internal brushes 5045 are evenly distributed on the inner side of the annular thick plate 5044. The bevel concave shell 5047 has an annular shape with an inclined inner side. When in use, the pipe cleaning device 5 is adjusted to a position above the transparent test tube 1 and at a certain distance from the top of the transparent test tube 1 for easy placement of the sample. The water pump 10 is started to pump the water in the water tank 11 into the annular water passing plate 9, and then the annular water passing plate 9 fills the transparent test tube 1 with water. Then the sample is placed in the transparent test tube 1 and completely immersed in the water. Then the pipe cleaning device 5 is adjusted again to contact the top of the transparent test tube 1 to block it. When the sample is soaked and permeated in the water, the rotating block 14 can be manually rotated to drive the perforated round block 13 to rotate until the perforated round block 13 rotates to communicate with the air outlet of the air pump 16. At this time, the air pump 16 is started to inflate and pressurize the inside of the transparent test tube 1 through the perforated round block 13 and the annular water passing plate 9, so that the osmotic pressure of the sample inside the transparent test tube 1 in the water changes, and then the permeation effect of the sample under different pressures can be observed. At the same time, a plurality of round holes with different pore diameters are opened on the porous plate 17 in the transparent test tube 1 to facilitate the fine particles carried away during the seepage process to pass through. The carried-away fine particles enter the funnel 18 through the porous plate 17 and then precipitate at the bottom of the transparent test tube 1 through the funnel 18. After waiting for a period of time, the pipe cleaning device 5 is adjusted again to a position above the transparent test tube 1 and at a certain distance from the top of the transparent test tube 1. At this time, the sample in the transparent test tube 1 can be taken out and the water level in the transparent test tube 1 can be observed to obtain the permeability of the sample. After observing the data, the electric push rod 7 drives the drainage device 6 at the top to move downward until it disengages from the contact with the transparent test tube 1, that is, no longer blocks the bottom of the transparent test tube 1. At this time, the water in the transparent test tube 1 drains downward into the drainage device 6, and then the pipe cleaning device 5 is adjusted to move downward and enter the transparent test tube 1 to clean the dust and other sundries on its inner wall and absorb the residual water. After cleaning, the electric push rod 7 can be used to push the drainage device 6 upward to block the bottom of the transparent test tube 1, so as to conduct the sample penetration test again. The drive shaft at the bottom is driven by the bidirectional electric telescopic rod 503 to drive the outer small sleeve block 502 and the bottom-mounted baffle 505 to move downward into the transparent test tube 1 together,When the small cover plate 5042 moves downward, it drives the outer sponge cover plate 501 to move downward together, and pulls the top corrugated connecting piece 507 to stretch downward. The sponge cover plate 501 moves down to the inside of the transparent test tube 1 and is in contact with the inner wall of the transparent test tube 1 at all times. The moving sponge cover plate 501 cleans the inner wall of the transparent test tube 1 and absorbs the undrained moisture. After the sponge cover plate 501 has cleaned the transparent test tube 1, the top driving shaft and the bottom driving shaft are driven by the two-way electric telescopic rod 503 to drive the sponge cover plate 501 to gradually move upward to the inside of the cleaning mechanism 504. At this time, the bottom baffle plate 505 and the sponge cover plate 501 are driven upward together by the driving shaft at the bottom of the two-way electric telescopic rod 503. When the small sleeve 5042 moves up to the top and contacts the parts of the cleaning mechanism 504, the bottom baffle 505 squeezes the sponge sleeve 501 from the bottom of the sponge sleeve 501 to drain the water and discharge the absorbed residual water. A part of the water discharged from the sponge sleeve 501 will flow downward through the drainage circular hole 506. By opening a plurality of drainage circular holes 506, it is convenient to fully discharge the water between the sponge sleeve 501 and the bottom baffle 505. When the small sleeve 5042 moves up, it pushes the top corrugated connecting piece 507 to contract upward in a corrugated manner. When the corrugated connecting piece 507 stretches and contracts, it wraps and covers the connection between the driving shaft at the bottom of the two-way electric telescopic rod 503 at all times. When the sponge sleeve 501 moves up to the top and contacts the annular sleeve 5041, The bottom baffle plate 505 which continues to move upward will squeeze and drain the water. The sponge cover plate 501 is moved upward through the adjustment of the two-way electric telescopic rod 503 to pass through the corrugated ring piece 5048 and enter between the annular thick plate 5044. At this time, the arc-shaped long rod 5043 is manually pushed to drive the annular thick plate 5044 to rotate around the sponge cover plate 501. When the annular thick plate 5044 rotates, the built-in brush 5045 on the inside will rotate together. When the built-in brush 5045 rotates, it will always rub against the outer side surface of the sponge cover plate 501, that is, the surface in contact with the inner wall of the transparent test tube 1. The rotating built-in brush 5045 rubs and cleans the outer side surface of the sponge cover plate 501, and the cleaned dust and squeezed liquid will fall on the corrugated ring piece 5048 , and slides down along the inclined path of the corrugated ring piece 5048 to the inside of the inclined concave shell 5047. The inclined concave shell 5047 is arranged at the bottom of the annular thick plate 5044 to facilitate the storage of the cleaned dust and the squeezed liquid. The presence of liquid and dust in the inclined concave shell 5047 can also achieve a certain dust reduction effect to prevent the dust from flying. The corrugated ring piece 5048 arranged inside the inclined concave shell 5047 covers most of the bottom area of ​​the sponge sleeve 501 and facilitates the passage of the sponge sleeve 501. When the sample needs to be tested again after cleaning, the two-way electric telescopic rod 503 can be used to drive the annular sleeve 5041 to move down to the top of the transparent test tube 1 and seal its top. ,

There are multiple second arc holes 606, and the multiple second arc holes 606 are evenly distributed on the outside of the second ring plate 605. There are three curved scraping rods 608, and the three curved scraping rods 608 are evenly distributed on the top of the second ring plate 605. There are multiple arc-shaped barbs 609, and the multiple arc-shaped barbs 609 are respectively distributed on both sides of the curved scraping rod 608. When in use, after the test is over, the electric push rod 7 drives the circular inclined platform 602 at the top to move downward. The downward movement of the circular inclined platform 602 drives the bottom plug 601 at the top and the first ring plate 603 on the outside to move downward together. After the bottom plug 601 moves downward to release the blockage of the bottom of the transparent test tube 1, the tested liquid in the transparent test tube 1 drains downward onto the circular inclined platform 602. By providing the circular inclined platform 602, the liquid discharged after multiple tests is collected and stored. When the liquid on the circular inclined platform 602 accumulates to a height close to the transparent test tube 1, the second ring plate 605 is manually rotated through the arc-shaped grip 607 to drive the second arc hole 606 opened on its outside to rotate to a position aligned with the first arc hole 604 of the first ring plate 603. At this time, the liquid on the circular inclined platform 602 can be discharged outward through the first arc hole 604 and the second arc hole 606. By opening the first arc hole 604 and the second arc hole 606, the liquid in the circular inclined platform 602 is stored and discharged. When the second ring plate 605 rotates, it drives the curved scraping rod 608 at the top to rotate together. When the curved scraping rod 608 rotates, it is always in contact with the inner side surface of the first ring plate 603 and the inclined surface of the circular inclined platform 602. The rotating curved scraping rod 608 scrapes and cleans the inner side surface of the first ring plate 603 and the inclined surface of the circular inclined platform 602. When the curved scraping rod 608 rotates, it drives the arc-shaped barbs 609 on both sides to move together. The arc-shaped barbs 609 intermittently penetrate into the first arc hole 604 as the curved scraping rod 608 rotates.

[0054] When the present invention is in operation, the pigging device 5 is adjusted to a position above the transparent test tube 1 and at a certain distance from the top of the transparent test tube 1 to facilitate placing the sample. The water pump 10 is started to pump the water in the water tank 11 into the annular water passing plate 9, and then the annular water passing plate 9 adds water into the transparent test tube 1. Then the sample is placed in the transparent test tube 1 and completely immersed in the water. Then the pigging device 5 is adjusted again to contact the top of the transparent test tube 1 to block it. When the sample is soaked and permeated in the water, the rotating block 14 can be manually rotated to drive the perforated round block 13 to rotate until the perforated round block 13 rotates to communicate with the air outlet of the air pump 16. At this time, the air pump 16 is started to inflate and pressurize the inside of the transparent test tube 1 through the perforated round block 13 and the annular water passing plate 9, so that the osmotic pressure of the sample inside the transparent test tube 1 in the water changes, and then the osmotic effect of the sample under different pressures can be observed. At the same time, a plurality of round holes with different apertures are formed on the porous plate 17 in the transparent test tube 1 to facilitate the fine particles carried away during the seepage process to pass through. The carried-away fine particles enter the funnel 18 through the porous plate 17 and then precipitate at the bottom of the transparent test tube 1 after passing through the funnel 18. After waiting for a period of time, the pigging device 5 is adjusted again to a position above the transparent test tube 1 and at a certain distance from the top of the transparent test tube 1. At this time, the sample in the transparent test tube 1 can be taken out and the water level in the transparent test tube 1 can be observed to obtain the permeability of the sample. After observing the data, the electric push rod 7 drives the drainage device 6 at the top to move downward until it disengages from the contact with the transparent test tube 1, that is, no longer blocks the bottom of the transparent test tube 1. At this time, the water in the transparent test tube 1 drains downward into the drainage device 6. Then the pigging device 5 is adjusted to move downward and enter the transparent test tube 1 to clean the inner wall of the transparent test tube 1 of dust and other sundries and absorb the remaining moisture. After cleaning, the electric push rod 7 can be used to push the drainage device 6 upward to block the bottom of the transparent test tube 1, so as to conduct the osmosis test of the sample again. The bidirectional electric telescopic rod 503 drives the driving shaft at the bottom to drive the small sleeve block 502 on the outside and the bottom baffle 505 at the bottom to move downward into the transparent test tube 1 together. When the small sleeve plate 5042 moves downward, it drives the sponge sleeve plate 501 on the outside to move downward together and pulls the corrugated connecting piece 507 at the top to stretch downward. When the sponge sleeve plate 501 moves downward into the transparent test tube 1, it is always in contact with the inner wall of the transparent test tube 1. The moving sponge sleeve plate 501 cleans the inner wall of the transparent test tube 1 and absorbs the undrained moisture. After the sponge sleeve plate 501 finishes cleaning the transparent test tube 1, the bidirectional electric telescopic rod 503 drives the driving shaft at the top and the driving shaft at the bottom to drive the sponge sleeve plate 501 to gradually move upward into the cleaning mechanism 504. At this time, the driving shaft at the bottom of the bidirectional electric telescopic rod 503 drives the bottom baffle 505 and the sponge sleeve plate 501 to move upward together. When the sponge sleeve plate 501 moves upward to the top and abuts against the components of the cleaning mechanism 504, the bottom baffle 505 squeezes the sponge sleeve plate 501 from the bottom of the sponge sleeve plate 501 to drain the absorbed remaining moisture, and a part of the moisture discharged from the sponge sleeve plate 501 will flow downward through the liquid discharge round hole 506.By opening a plurality of liquid drainage round holes 506, it is convenient for the moisture between the sponge sleeve plate 501 and the bottom baffle 505 to be fully discharged. When the small sleeve plate 5042 moves upward, it pushes the waveform connecting piece 507 at the top to contract upward in a waveform. When the waveform connecting piece 507 extends and contracts, it always wraps and covers the connection part of the driving shaft at the bottom of the bidirectional electric telescopic rod 503. When the sponge sleeve plate 501 moves upward to the top and contacts the annular sleeve plate 5041, it will be squeezed to drain water by the continuously upward moving bottom baffle 505. The sponge sleeve plate 501 is adjusted by the bidirectional electric telescopic rod 503 to move upward through the waveform ring piece 5048 and enter between the annular thick plates 5044. At this time, manually push the arc-shaped long rod 5043 to drive the annular thick plate 5044 to rotate around the sponge sleeve plate 501. When the annular thick plate 5044 rotates, it drives the built-in brush 5045 inside to rotate together. When the built-in brush 5045 rotates, it always makes frictional contact with the outer side surface of the sponge sleeve plate 501, that is, the surface in contact with the inner wall of the transparent test tube 1. The rotating built-in brush 5045 frictionally cleans the outer side surface of the sponge sleeve plate 501. The dust and the squeezed-out liquid will fall on the waveform ring piece 5048 and slide down along the inclined surface path of the waveform ring piece 5048 to the inside of the inclined surface concave shell 5047. By arranging the inclined surface concave shell 5047 at the bottom of the annular thick plate 5044, it is convenient to store the cleaned dust and the squeezed-out liquid. The coexistence of liquid and dust in the inclined surface concave shell 5047 can also achieve a certain dust reduction effect to avoid the phenomenon of dust flying. The waveform ring piece 5048 arranged inside the inclined surface concave shell 5047 covers most of the area at the bottom of the sponge sleeve plate 501 and is convenient for the sponge sleeve plate 501 to pass through. When it is necessary to test the sample again after the cleaning is completed, the bidirectional electric telescopic rod 503 can be used to drive the annular sleeve plate 5041 to move downward to the top of the transparent test tube 1 and block its top. After the test is completed, the electric push rod 7 drives the circular inclined platform 602 at the top to move downward. The downward movement of the circular inclined platform 602 drives the bottom plug 601 at the top and the first ring plate 603 on the outside to move downward together. After the bottom plug 601 moves downward to release the blockage of the bottom of the transparent test tube 1, the tested liquid in the transparent test tube 1 drains downward onto the circular inclined platform 602. By arranging the circular inclined platform 602, the liquid discharged after multiple tests is collected and stored. When the liquid on the circular inclined platform 602 accumulates to be about to approach the height of the transparent test tube 1, manually rotate the second ring plate 605 through the arc-shaped handle 607 to drive the second arc hole 606 opened on its outside to rotate to a position aligned with the first arc hole 604 of the first ring plate 603. At this time, the liquid on the circular inclined platform 602 can be discharged outward through the first arc hole 604 and the second arc hole 606. By opening the first arc hole 604 and the second arc hole 606, the liquid in the circular inclined platform 602 is stored and discharged. When the second ring plate 605 rotates, it drives the curved scraping rod 608 at the top to rotate together. When the curved scraping rod 608 rotates, it always makes contact with the inner side surface of the first ring plate 603 and the inclined surface of the circular inclined platform 602.The rotating curved scraping rod 608 scrapes and cleans the inner side of the first ring plate 603 and the inclined surface of the circular inclined table 602. When the curved scraping rod 608 rotates, it drives the arc-shaped barbs 609 on both sides to move together, and the arc-shaped barbs 609 intermittently penetrate into the first arc holes 604 as the curved scraping rod 608 rotates.
