[0034] See Figures 1-5 This utility model provides an unattended intelligent permeameter, especially a permeameter used to perform destructive experiments on crushed stone and gravel, including an intelligent control main water inlet device 4 and multiple intelligent permeation measurement units;

[0035] Each intelligent permeation measurement unit includes a cylinder 1, a top pressurization system 2, and a bottom water inlet structure 3;

[0036] See Figure 2 The cylinder 1 includes a water pressure sensor 1.3, a flow recorder 1.4, a return water pipe 1.5, and the cylinder body 1.6; see reference. Figure 4 The bottom water inlet structure 3 includes a uniformly distributed water inlet plate 3.1, a water inlet pipe 3.2, and a sealing rubber ring 3.3;

[0037] Multiple water pressure sensors 1.3 are installed at different heights on the side of the tank body 1.6; a sealing rubber ring 3.3 is installed at the bottom of the tank body 1.6; a uniformly distributed water inlet plate 3.1 is fixedly installed above the sealing rubber ring 3.3 and inside the tank body 1.6; the uniformly distributed water inlet plate 3.1 has multiple uniformly distributed water inlet holes. One end of the water inlet pipe 3.2 is connected to the uniformly distributed water inlet plate 3.1; the other end of the water inlet pipe 3.2 is connected to an osmometer interface 4.3 of the intelligent control main water inlet device 4; a top pressurization system 2 is installed on the top of the tank body 1.6; a return water inlet is opened on the side of the tank body 1.6, above each water pressure sensor 1.3; a flow recorder 1.4 is installed at the return water inlet and is connected to one end of the return water pipe 1.5.

[0038] In practical applications, the tank body 1.6 is made of high-strength transparent material. The top of the tank body 1 has an upper flange 1.1 for mounting the top pressurization system 2; the bottom of the tank body 1 has a lower flange 1.2 for mounting the bottom water inlet structure 3.

[0039] See Figure 5 The intelligent control main water inlet device 4 includes a data processing assembly 4.1, a power pump 4.2, an osmometer interface 4.3, and a water tank interface 4.4; the intelligent control main water inlet device 4 is a key structure for unattended operation.

[0040] The power pump 4.2 is electrically connected to the data processing assembly 4.1; the water inlet of the power pump 4.2 is connected to the water tank interface 4.4; the power pump 4.2 has multiple water outlets; each water outlet is equipped with a permeameter interface 4.3 for connecting to the water inlet pipe 3.2 of the bottom water inlet structure 3.

[0043] The unattended intelligent permeabilizer provided by this utility model has the following characteristics:

[0044] (1) The traditional permeameter barrel is mainly made of iron and PVC. Iron is prone to rust after repeated use and will block the pipeline; PVC has low strength and the barrel may crack when the pressure is high, thus making it impossible to complete the permeameter experiment.

[0045] In this application, the barrel body 1.6 is made of high-strength transparent material, which facilitates observation of the sample breakage and has high strength;

[0046] (2) In this application, multiple water pressure sensors 1.3 are installed at different heights on the side of the barrel 1.6; they can simultaneously and accurately measure water pressure at different heights.

[0047] (3) In this application, a flow recorder 1.4 is installed at the return water inlet of the tank 1.6, which can accurately measure the overflow water flow in real time;

[0048] (4) In this application, the remote control center is connected to the water pressure sensor 1.3, the flow recorder 1.4, the sensing fastening plate 2.3, the data processing assembly 4.1, and the power pump 4.2. The remote control center can use a PLC controller to remotely control the permeation test parameters, including: controlling the water pressure through the sensing fastening plate 2.3; controlling the inlet flow rate through the power pump 4.2; and collecting the test parameters in real time during the permeation test, including: the water pressure collected in real time by each water pressure sensor 1.3 and the outlet flow rate collected by the flow recorder 1.4. This enables remote control of the permeation test and remote acquisition of test parameters, achieving unattended operation, reducing personnel workload, and timely data acquisition, which can accurately analyze the water pressure change trend per unit time. Therefore, human error can be eliminated, and the accuracy of permeameter sample measurement can be improved.

[0049] (5) In this application, the outflow rate is collected in real time by the flow recorder 1.4 to ensure the timeliness of the collection and avoid problems caused by evaporation. The method of this application can improve the accuracy of the experimental results.

[0050] (6) In this application, the intelligent control main water inlet device 4 can be connected to multiple intelligent permeation measurement units to carry out multiple permeation tests at the same time, thereby improving the efficiency of the test.

[0051] This utility model provides an unattended intelligent permeameter, one testing method of which is as follows:

[0052] ① The sample is saturated.

[0053] Three samples were added to the barrels 1.6 of the three intelligent osmosis measurement units, and then the evenly distributed water inlet plate 3.1 and sealing rubber ring 3.3 of the bottom water inlet structure 3 were fitted into the inside of the barrels 1.6. This connected the water inlet pipe 3.2 to the osmosis instrument interface 4.3 of the intelligent control main water inlet device 4.

[0054] The power pump 4.2 is started, and external water head is introduced through the inlet pipe 3.2, entering the barrel 1.6 through the evenly distributed inlet plate 3.1, gradually raising the water head until the sample is saturated. In order to improve the sealing between the bottom water inlet structure 3 and the barrel 1.6, a sealing rubber ring 3.3 is added to prevent water leakage.

[0055] ② Apply pressure to the sample.

[0056] For samples with larger particle sizes, the loading plate 2.4 is used, while for samples with smaller particle sizes, it can be replaced with a porous permeable plate. For the top pressurization system 2, it is pre-tightened by the torsion bar 2.1, and then the pressure is gradually increased to the preset pressure by controlling the sensing fastening plate 2.3 through the data control terminal.

[0057] ③ Raise the water head.

[0058] The signal is transmitted to the data processing assembly 4.1 via the data control terminal, which controls the power pump 4.2 to supply water. Once the water pressure sensor 1.3 registers a reading, remote control can be performed.

[0059] ④ Experimentation and data collection.

[0060] The data processing assembly can automatically collect pressure data from the water pressure sensor 1.3 and water flow data from the flow recorder 1.4, and control the sensing fastening plate 2.3 to pressurize or depressurize the sample, control the pressure and flow rate of the water entering the power pump 4.2, and can periodically summarize and record the above data and transmit it to the data control terminal via wireless communication.

[0061] This utility model provides an unattended intelligent permeabilizer, which has the following advantages:

[0062] ① Three samples can be tested simultaneously to reduce errors caused by soil weathering and improve the efficiency of the permeability test;

[0063] ② It facilitates observation of sample breakage and has high strength;

[0064] ③ Accurately measure water pressure at different heights;

[0065] ④ Accurately measure the overflow water flow rate;

[0066] ⑤ Eliminate human error and improve the accuracy of permeameter sample measurement.

[0067] ⑥ Unmanned operation reduces the workload of personnel, and data is collected on a regular basis, which can accurately analyze the trend of water pressure change per unit time.
