Technical Field
[0001] This utility model relates to the field of engineering quality testing technology, specifically a permeameter for engineering quality testing. Background Technology
[0002] A permeameter for engineering quality testing is an instrument specifically designed for soil testing. It assesses the soil's permeability by measuring the rate at which water or other liquids permeate a soil sample under simulated pressure conditions. This is crucial for determining the soil's drainage performance, saturation, foundation stability, and predicting groundwater level changes. It is an indispensable key device in soil engineering property evaluation and geotechnical engineering design.
[0003] Authorization announcement number CN217717419U discloses a permeameter for testing the quality of building engineering. The technical solution is as follows: "It includes a fixed shell first, on which a fixed shell second is mounted. A driver is fixedly connected to the top of the fixed shell second, and a driving rod is fixedly connected to the output end of the driver, penetrating the fixed shell second. A pressing plate is fixedly connected to the other end of the driving rod. A connecting rod is fixedly connected to the lower inner wall of the fixed shell first, and a collecting cylinder is also provided at the bottom of the fixed shell first. The connecting rod extends into the collecting cylinder." The beneficial effects are: the pressing plate compacts the soil, thus avoiding excessive gaps between soil particles, resulting in more accurate test results. Furthermore, it allows moisture to be expelled from the soil during compaction, preventing it from affecting the test and facilitating soil testing.
[0004] The above technical solution has the following defects: the soil is squeezed by the back pressure plate inside the fixed shell, causing the soil to adhere to the inside of the fixed shell. Since the fixed shell cannot be disassembled, it is difficult to remove the soil adhering to its inner wall, thus affecting the subsequent soil testing. Therefore, a permeameter for engineering quality testing is proposed to solve the above-mentioned problems. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this utility model provides a permeameter for engineering quality testing, which has advantages such as easy removal of the squeezed soil. It solves the problem that after the soil is squeezed by existing testing permeameters, the soil adheres to the inside of the device. Because the device is difficult to disassemble and assemble, it is difficult to remove the soil adhering to the inner wall of the device, thus affecting the subsequent soil testing work.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A permeameter for engineering quality testing includes a housing, the outer wall of which is provided with a pressing structure, the outer wall of which is provided with a separation structure, and the bottom of which is provided with a discharge sealing structure;
[0008] The separation structure includes side plates fixedly connected to the left and right sides of the box body, four support bases fixedly connected to the bottom of the side plates, a base plate fixedly connected between the four support bases, a first cylinder fixedly connected to the top of the base plate, a placement platform fixedly connected to the telescopic shaft of the first cylinder, a support plate fixedly connected to the back of the box body, an electric slide fixedly connected to the bottom of the support plate, a connecting rod fixedly connected to the movable shaft of the electric slide, and a separation blade fixedly connected to the top of the connecting rod.
[0009] Furthermore, the clamping structure includes a support rod fixedly connected to the top of the side plate, a top plate fixedly connected to the top of the support rod, a second cylinder fixedly connected to the top of the top plate, and a pressure plate fixedly connected to the telescopic shaft of the second cylinder.
[0010] Furthermore, the discharge sealing structure includes a threaded rod rotatably connected inside the left side plate, a threaded ring threadedly connected to the outer peripheral wall of the threaded rod, an installation rod fixedly connected to the outer peripheral wall of the threaded ring, a sealing seat fixedly connected to the side of the installation rod away from the threaded ring, and a drain pipe fixedly connected to the bottom of the placement platform.
[0011] Furthermore, the sealing seat is slidably connected to the inner circumferential wall of the drain pipe, and the tops of both the sealing seat and the drain pipe are located at the same horizontal plane as the top of the placement platform.
[0012] Furthermore, a limiting rod is fixedly connected to the bottom of the housing, and a limiting hole is formed inside the limiting rod. The mounting rod is slidably connected inside the limiting hole, and the size of the mounting rod is adapted to the limiting hole.
[0013] Furthermore, a positioning seat is fixedly connected to the top of the base plate, and a collection bottle is slidably connected inside the positioning seat.
[0014] Furthermore, the support plate has a groove inside, the connecting rod is slidably connected inside the groove, and the separating blade is slidably connected to the top of the support plate.
[0015] Furthermore, a support frame is fixedly connected inside the box, the placement platform is movably connected to the top of the support frame, and the placement platform is slidably connected inside the box.
[0016] Compared with the prior art, this utility model provides a permeameter for engineering quality testing, which has the following beneficial effects:
[0017] The permeameter used for quality testing in this project uses a first cylinder to push the placement platform upwards. The placement platform scrapes and cleans the soil adhering to the inner wall of the chamber. The electric slide and connecting rod drive the separating blade to move closer to the soil. Because the cutting surface of the separating blade is inclined, it easily cuts and separates the soil adhering to the top of the placement platform, thus preventing the soil from adhering to the top of the placement platform, which is convenient for subsequent testing of other soil.
