Description

Technical Field

[0001] This utility model relates to the field of engineering construction technology, and in particular to a testing device for the permeability of solidified soil after it has been molded and solidified. Background Technology

[0002] Solidified soil is an engineering material formed by modifying traditional soil through specific technical means. Its core principle is to use solidifying agents such as cement, lime, and fly ash to undergo a physicochemical reaction with the particles in the soil, forming a cementing effect between the soil particles, thereby improving the strength, stability, and durability of the soil. Specifically, after the solidifying agent is mixed with the soil, a hydration reaction occurs to generate cementitious substances, which fill the soil pores and encapsulate the particles to form a dense structure.

[0003] Testing the permeability of solidified soil after it has been solidified is a crucial step in evaluating its impermeability and engineering application effectiveness. Existing testing devices typically place the solidified soil inside a testing chamber for permeability testing. However, current technology can lead to sidewall leakage during testing, making it impossible to ensure that water flows only through the pores inside the solidified soil during the test. This results in the measured permeation amount being greater than the actual permeation amount through the pores of the solidified soil, thus overestimating the permeability of the solidified soil and failing to accurately reflect its impermeability. Consequently, the test results vary significantly, which is detrimental to the quality control of the permeability of solidified soil. Utility Model Content

[0024] Example 1:

[0025] Reference Figures 1-4 This is the first embodiment of the present invention. This embodiment provides a device for testing the permeability of solidified soil after it has been formed and solidified. The device includes a cylinder 1, a support frame 2 fixed to the inner wall of the cylinder 1, a tank 3 installed on the top of the support frame 2, a solidified soil body 4 disposed inside the tank 3, an air-filled sleeve 5 for eliminating gaps in the inner wall of the tank 3 installed on the inner wall of the tank 3, a sealing component 6 disposed on the outer side of the solidified soil body 4, a liquid storage tank 7 installed on the top of the cylinder 1, a first liquid level sensor 8 installed on the top of the liquid storage tank 7, a water outlet pipe 9 connected to the bottom of the liquid storage tank 7, and a connecting hose 10 connected to the bottom of the water outlet pipe 9.

[0026] Tank 3 is used to place the solidified soil sample and is the main container for the permeation test. The air-filled sleeve 5 eliminates the gap between the inner wall of tank 3 and the solidified soil body 4 by inflating and expanding, preventing side wall leakage and ensuring the accuracy of the permeation test. The sealing component 6 further improves the sealing between the solidified soil body 4 and tank 3. The water or other permeation liquid required for the permeation test is stored in the storage tank 7. The permeation liquid is supplied to the inside of tank 3 through the water outlet pipe 9 and the connecting hose 10. The liquid level inside the storage tank 7 is monitored by the first liquid level sensor 8.

[0027] The sealing assembly 6 includes a protective membrane 61 installed on the outside of the solidified soil body 4, with a latex membrane 62 fixed to the inner wall of the protective membrane 61 and a silicone membrane 63 fixed to the outside of the protective membrane 61.

[0028] The protective film 61 is placed over the outside of the solidified soil body 4, and the latex film 62 is tightly attached to the sample to prevent the solidified soil particles from falling off and to serve as the first waterproof barrier. The silicone film 63 provides the main waterproof function and further enhances the sealing performance.

[0034] The sealing cap 13 is fixed to the top of the tank 3 with bolts, sealing the tank 3 and connecting it to the connecting hose 10, allowing the permeate to enter the tank 3. The sealing gasket at the bottom of the sealing cap 13 further enhances the sealing performance of the tank 3. The first liquid level sensor 8 and the second liquid level sensor 14 are both existing technologies, with the same structure and working principle as the liquid level sensor in application number CN202323273111.3, used to monitor the liquid level height. As they are existing technologies, they will not be described in detail here. The second liquid level sensor 14 achieves the effect of monitoring the liquid level inside the tank 3, thereby calculating the permeate volume. The drain pipe 15 is used to drain the liquid after the test, facilitating cleaning and the next round of testing.

[0035] Example 3:

[0036] This is the third embodiment of the present invention, which is based on the first two embodiments.

[0037] Specifically, a mounting bracket 16 is fixed to the bottom of the support frame 2, and a limit bracket 17 is fixed to the inner wall of the mounting bracket 16.

[0038] The mounting bracket 16 is provided in two sets, and the limiting bracket 17 facilitates the subsequent installation of equipment and the subsequent collection of leaked liquid from the tank 3.

[0039] Specifically, the inner wall of the limiting frame 17 is fitted with an installation block 18, and a collection box 19 for collecting leakage from the tank 3 is fixed on one side of the installation block 18.

[0040] The mounting block 18 is snapped into the limiting frame 17 to fix the collection box 19. The collection box 19 is used to collect the leakage from the tank 3 to prevent the liquid from leaking into the cylinder 1 and causing pollution or affecting the test results. At the same time, it can collect the liquid discharged from the drain pipe 15.

[0041] Specifically, a fixing sleeve 20 is fixed to the outside of the liquid storage tank 7, and a support rod 21 is fixed to the outside of the fixing sleeve 20. One end of the support rod 21 is fixedly connected to the top of the cylinder 1.

[0045] In use, the protective film 61 is placed over the outside of the solidified soil body 4, and the latex film 62 is tightly attached to the sample to prevent the solidified soil particles from falling off and to act as the first waterproof barrier. The silicone film 63 provides the main waterproof function and further enhances the sealing. The solidified soil body 4 is placed inside the tank 3, and air is injected into the air sleeve 5 through the air inlet 11 to expand it and fit the sample, effectively preventing side wall leakage. This ensures that water flows only through the internal pores of the sample during the permeation test, improving the accuracy of the test. The sealing ring 12 enhances the sealing of the tank 3 and prevents liquid leakage. Then, the sealing cap 13 is fixed to the top of the tank 3 with bolts to seal the tank 3 and connect it to the connecting hose 10, allowing the permeate to enter the tank 3. The sealing gasket at the bottom of the sealing cap 13 further enhances the sealing of the tank 3. The storage tank 7 stores the water or other permeate required for the permeation test. The permeate is supplied to the tank body 3 through the outlet pipe 9 and the connecting hose 10. The liquid level inside the storage tank 7 is monitored by the first liquid level sensor 8. When permeation occurs inside the solidified soil body 4, the permeation volume can be calculated by comparing the liquid level changes in the storage tank 7 and the tank body, thereby evaluating the permeation efficiency of the solidified soil. The mounting block 18 is snapped into the limiting frame 17 to fix the collection box 19. The collection box 19 is used to collect the liquid leaking from the tank body 3 to prevent the liquid from leaking into the cylinder 1 and causing pollution or affecting the test results. At the same time, it can collect the liquid discharged from the drain pipe 15. The collection cover 22 is used to collect or guide the liquid leaking around the storage tank 7 to prevent it from spreading. The viewing window 23 facilitates observation of the liquid level and liquid condition inside the storage tank 7.
