Description

Technical Field

[0001] The invention relates to the technical field of vertical permeameters, in particular to a vertical permeameter used for geotechnical tests. Background Art

[0002] Testing the permeability of geosynthetics in geotechnical tests is a particularly important step. Geosynthetics is a 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 rubber, etc.) as raw materials to make various types of products, which are placed inside, on the surface or between various soil bodies to strengthen or protect the soil. Geosynthetics, as a new type of geotechnical engineering material, is known internationally as the "fourth largest building material" after steel, cement, and wood. With the development of my country's infrastructure, 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] The existing geosynthetics are easily contaminated or mixed with dust, mud and other debris on the surface or inside during production or use. These dust and mud are often discharged after water penetrates and dilutes the geosynthetics. After multiple tests, the remaining dust, mud and other debris accumulate in the test tube where the test products are stored, seriously affecting the accuracy of subsequent tests. Therefore, we proposed a vertical permeameter for geotechnical tests. Summary of the invention

A plurality of built-in brushes 5045 are provided, and the plurality of built-in brushes 5045 are evenly distributed on the inner side of the annular thick plate 5044. The inclined concave shell 5047 has an annular shape with an inclined inner side. When in use, the cleaning device 5 is adjusted to a position above the transparent test tube 1 and 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 water in the water tank 11 into the annular water-passing plate 9, and then the annular water-passing plate 9 adds water to the transparent test tube 1. The sample is then placed in the transparent test tube 1 and completely immersed in water. The cleaning device 5 is then adjusted again to contact the top of the transparent test tube 1 to seal it. When the sample is immersed and infiltrated in water, the rotating block 14 can be manually rotated to drive the perforated round block 13 Rotate until the perforated round block 13 rotates to be connected with the air outlet of the air pump 16. At this time, start the air pump 16 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 in the water inside the transparent test tube 1 changes, and then observe the osmotic effect of the sample under different pressures. At the same time, a plurality of circular holes with different apertures are opened on the porous plate 17 in the transparent test tube 1 to facilitate the passage of fine particles carried away during the seepage process. The carried away fine particles pass through the porous plate 17 and enter the funnel 18, and then pass through the funnel 18 and settle at the bottom of the transparent test tube 1. After waiting for a period of time, the pipe cleaning device 5 is again moved to the 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 then The water level of the transparent test tube 1 is observed to obtain the permeability of the sample. After observing the data, the electric push rod 7 drives the drainage device 6 on the top to move downward until it is out of contact with the transparent test tube 1, that is, the bottom of the transparent test tube 1 is no longer blocked. At this time, the water in the transparent test tube 1 is discharged downward into the drainage device 6, and then the cleaning 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 to clean the dust and other debris and absorb the residual water. After cleaning, the drainage device 6 can be pushed upward by the electric push rod 7 to block the bottom of the transparent test tube 1, so as to conduct the permeability test of the sample again, and 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.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. ,

[0053] For the second embodiment, please refer to Figure 1-Figure 9The present invention provides a vertical permeameter for geotechnical testing: the drainage device 6 includes a bottom-mounted block 601, the bottom of the bottom-mounted block 601 is fixedly connected to a circular inclined platform 602, the outer side of the circular inclined platform 602 is sleeved and fixedly connected to a first ring plate 603, the outer side of the first ring plate 603 is provided with a first arc hole 604, the outer side of the first ring plate 603 is rotatably connected to a second ring plate 605 through a bearing, the outer side of the second ring plate 605 is provided with a second arc hole 606, the outer side of the second ring plate 605 is fixedly connected to an arc handle 607, the top of the second ring plate 605 is fixedly connected to a curved scraper rod 608, and both sides of the curved scraper rod 608 are fixedly connected to arc-shaped barbed strips 609, the bottom of the circular inclined platform 602 is fixedly connected to the driving shaft of the electric push rod 7, a plurality of first arc holes 604 are provided, and the plurality of first arc holes 604 are evenly distributed on the outside of the first ring plate 603, a plurality of second arc holes 606 are provided, and the plurality of second arc holes 606 are evenly distributed on the outside of the second ring plate 605, three curved scraper rods 608 are provided, and the three curved scraper rods 608 are evenly distributed on the top of the second ring plate 605, a plurality of arc-shaped thorn bars 609 are provided, and the plurality of arc-shaped thorn bars 609 are respectively distributed on both sides of the curved scraper rod 608. When in use, after the test is completed, the electric push rod 7 drives the top circular inclined platform 602 to move down, and the circular inclined platform 602 moves down The bottom blocking block 601 at the top and the first ring plate 603 on the outside are driven to move downward together. After the bottom blocking block 601 moves downward to be free from the blockage on the bottom of the transparent test tube 1, the tested liquid in the transparent test tube 1 is discharged downward onto the circular inclined platform 602. The circular inclined platform 602 is provided to collect and store the liquid discharged after multiple tests. 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 by the arc handle 607 to drive the second arc hole 606 on the outside thereof 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 pass through the first arc hole 60 4 and the second arc hole 606 are discharged outward, and the liquid in the circular inclined platform 602 is stored and discharged by opening the first arc hole 604 and the second arc hole 606. When the second ring plate 605 rotates, it drives the curved scraper 608 on the top to rotate together. When the curved scraper 608 rotates, it always contacts the inner side surface of the first ring plate 603 and the inclined surface of the circular inclined platform 602. The rotating curved scraper 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 scraper 608 rotates, it drives the arc-shaped barbs 609 on both sides to move together. The arc-shaped barbs 609 intermittently pierce into the first arc hole 604 as the curved scraper 608 rotates.

[0054] When the present invention is operated and used, the cleaning device 5 is adjusted to a position above the transparent test tube 1 and a certain distance away from the top of the transparent test tube 1 for convenient 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 adds water into the transparent test tube 1, and then the sample is placed in the transparent test tube 1 and completely immersed in the water, and then the cleaning device 5 is adjusted again to contact with the top of the transparent test tube 1 to seal it. When the sample is immersed and penetrated 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 be connected 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 sample inside the transparent test tube 1 is immersed in the water. The osmotic pressure changes, and then the osmotic effect of the sample under different pressures is observed. At the same time, a plurality of circular holes with different apertures are provided on the porous plate 17 in the transparent test tube 1 to facilitate the passage of fine particles carried away during the seepage process. The carried away fine particles pass through the porous plate 17 and enter the funnel 18, and then pass through the funnel 18 to settle at the bottom of the transparent test tube 1. After waiting for a period of time, the cleaning device 5 is again moved to the 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 of 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 on the top to move downward until it is out of contact with the transparent test tube 1, that is, the bottom of the transparent test tube 1 is no longer blocked. At this time, the permeability The water in the transparent test tube 1 is discharged downward into the drainage device 6, and then the cleaning 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 to clean the dust and other debris and absorb the residual water. After cleaning, the drainage device 6 can be pushed upward by the electric push rod 7 to seal the bottom of the transparent test tube 1, so as to carry out the penetration test of the sample again. The driving shaft at the bottom is driven by the two-way electric telescopic rod 503 to drive the small sleeve block 502 on the outside and the bottom baffle plate 505 on the bottom to move downward into the transparent test tube 1. 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 on the top to stretch downward. When the sponge sleeve plate 501 moves down to the inside of the transparent test tube 1, it is in contact with the inner wall of the transparent test tube 1 at all times, and moves The sponge cover 501 cleans the inner wall of the transparent test tube 1 and absorbs the undrained water. After the sponge cover 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 501 to gradually move upward to the inside of the cleaning mechanism 504. At this time, the bottom baffle 505 and the sponge cover 501 are driven by the bottom driving shaft of the two-way electric telescopic rod 503 to move upward together. When the sponge cover 501 moves up to the top and conflicts with the parts of the cleaning mechanism 504, the bottom baffle 505 squeezes the sponge cover 501 from the bottom of the sponge cover 501 to drain the water and discharge the absorbed residual water. A part of the water discharged from the sponge cover 501 will flow downward through the drainage circular hole 506.By opening a plurality of drainage circular holes 506, it is convenient for the water between the sponge sleeve 501 and the bottom baffle plate 505 to be fully discharged. When the small sleeve plate 5042 moves up, it pushes the top corrugated connecting piece 507 to shrink upward in a corrugated manner. When the corrugated connecting piece 507 stretches and shrinks, it is always wrapped and covered with the connection between the driving shaft at the bottom of the two-way electric telescopic rod 503. When the sponge sleeve 501 moves up to the top and contacts the annular sleeve 5041, it will be squeezed and drained by the bottom baffle plate 505 that continues to move upward. The sponge sleeve 501 is adjusted by 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 sleeve 501. When 5044 rotates, it drives the built-in brush 5045 on the inside to rotate together. When the built-in brush 5045 rotates, it is in friction contact with the outer side surface of the sponge sleeve 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 sleeve 501. The cleaned dust and squeezed liquid will fall on the corrugated ring piece 5048 and slide down along the inclined path of the corrugated ring piece 5048 to the inner side of the inclined concave shell 5047. By arranging the inclined concave shell 5047 at the bottom of the annular thick plate 5044, it is convenient to store the cleaned dust and squeezed liquid. The presence of liquid and dust in the inclined concave shell 5047 can also achieve a certain dust reduction effect to prevent dust from flying. The corrugated ring piece 5048 arranged on the inner side of 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 annular sleeve 5041 can be driven by the two-way electric telescopic rod 503 to move down to the top of the transparent test tube 1 and seal the top. After the test, the circular inclined platform 602 on the top is driven downward by the electric push rod 7. The downward movement of the circular inclined platform 602 drives the bottom blocking block 601 on the top and the first ring plate 603 on the outside to move downward together. After the bottom blocking block 601 moves down to break away from the blockage on the bottom of the transparent test tube 1, the tested liquid in the transparent test tube 1 is discharged downward onto the circular inclined platform 602. By setting the circular inclined platform 602 for multiple tests The liquid discharged after the circular inclined platform 602 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 by the arc-shaped handle 607 to drive the second arc hole 606 opened on the outer side thereof 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 to the outside through the first arc hole 604 and the second arc hole 606. The liquid in the circular inclined platform 602 is stored and discharged by opening the first arc hole 604 and the second arc hole 606. When the second ring plate 605 rotates, it drives the curved scraper 608 on the top to rotate together. When the curved scraper 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 scraper 608 scrapes and cleans the inner side of the first ring plate 603 and the inclined surface of the circular inclined platform 602. When the curved scraper 608 rotates, it drives the arc-shaped thorn bars 609 on both sides to move together. The arc-shaped thorn bars 609 intermittently pierce into the first arc hole 604 as the curved scraper 608 rotates.
