Furthermore, excessive water injection can easily affect the test results of the soil permeability coefficient. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a soil permeability testing device. This addresses the issue that existing soil permeability testing devices typically require manual control of water injection into the ring during use, which is cumbersome, affects work efficiency, and can easily influence the test results of the soil permeability coefficient when too much water is injected.

[0006] The purpose and effectiveness of this utility model's soil permeability testing device are achieved through the following specific technical means:

[0007] A soil permeability testing device includes a top plate, an outer ring, supporting rods, a bottom plate, measuring cylinders, water inlets, a connecting frame, an inner ring, an installation mechanism, and a water filling mechanism. Multiple supporting rods are fixedly connected to the lower end face of the top plate. The bottom plate is fixedly connected to the outer side of the lower ends of the multiple supporting rods. Two measuring cylinders are fixedly connected to the upper end face of the bottom plate. Two water inlets are fixedly connected to the upper end faces of the two measuring cylinders respectively. The connecting frame is fixedly connected to the inner side of the outer ring. The inner ring is fixedly connected to the inner side of the connecting frame. The installation mechanism is located at the lower end of the outer ring. The water filling mechanism is located inside the outer ring.

[0008] Furthermore, the mounting mechanism includes: a handle and a toothed ring; there are two handles, both of which are fixedly connected to the outside of the outer ring; there are two toothed rings, which are respectively fixedly connected to the lower end faces of the outer ring and the inner ring.

[0009] Furthermore, the water filling mechanism includes: a fixed rod, a sliding block, a water inlet, a water outlet, and a water supply pipe; there are two fixed rods, which are respectively fixedly connected to the inner sides of the outer ring and the inner ring; there are two sliding blocks, which are respectively slidably connected to the inner sides of the two fixed rods; there are two water inlets, which are respectively fixedly connected to the upper ends of the two sliding blocks; there are two water outlets, which are respectively fixedly connected to the outer sides of the two sliding blocks; there are two water supply pipes, the upper ends of which are respectively fixedly connected to the lower ends of the two measuring cylinders, and the lower ends of which are respectively inserted into the two water inlets.

[0010] Furthermore, the water filling mechanism also includes: scale lines, indicator rods, and threaded shafts; the scale lines are provided in two sets, and the two sets of scale lines are respectively opened on the outside of the two fixed rods; the indicator rods are provided in two sets, and the two indicator rods are respectively fixedly connected to the outside of the two sliding blocks; the threaded shafts are provided in two sets, and the two threaded shafts are respectively rotatably connected to the inside of the two fixed rods, and the two threaded shafts are respectively threadedly connected to the two sliding blocks.

[0011] Furthermore, the water filling mechanism also includes: a sealing plate and a buoyancy plate; there are two sealing plates, which are slidably connected to the inner sides of two sliding blocks respectively; there are two buoyancy plates, which are fixedly connected to the lower end faces of the two sealing plates respectively.

[0012] Furthermore, the water filling mechanism also includes: a connecting hose, a water injection block, and a water injection trough; there are two connecting hoses, which are respectively inserted into the outside of the two water outlets; there are two water injection blocks, which are respectively fixedly connected to the lower ends of the two connecting hoses; there are two water injection troughs, which are respectively opened on the inside of the two water injection blocks.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This utility model, through its installation mechanism, enables the installation of testing equipment. After the toothed ring is pressed against the ground, pressing down and rotating the handle causes the handle to rotate the outer and inner rings. This rotation of the outer and inner rings drives the toothed ring to rotate, cutting the ground and facilitating the insertion of the outer and inner rings into the ground, thus improving work efficiency and reducing labor intensity. The water filling mechanism ensures a constant water level in the outer and inner rings. Rotating the threaded shaft causes the sliding block to slide under the action of the threaded connection with the threaded shaft. By observing the scale indicated by the indicator rod, the sliding block is adjusted to a suitable position. Water is then injected into the outer and inner rings through the measuring cylinder. The water flows through the water supply pipe, inlet, outlet, and connecting hose, and then flows out through the water injection block, filling the outer and inner rings. When the water level in the outer and inner rings reaches a certain height, the buoyancy plate slides upward under the action of buoyancy, causing the sealing plate to block the sliding block. At this time, the water injection block stops injecting water. As the water in the outer and inner rings seeps into the soil, the water level drops, and the sealing plate opens again, keeping the water level in the outer and inner rings at a constant height. After the measurement is completed, the soil permeability is calculated by reading the water consumption scale on the measuring cylinder. No manual operation is required, which improves work efficiency, reduces labor intensity, and ensures the accuracy of test results. Through the above mechanism, the installation of the testing equipment is realized, work efficiency is improved, labor intensity is reduced, and the constant water level in the outer and inner rings is achieved, which also improves work efficiency, reduces labor intensity, and ensures the accuracy of test results.

After the measurement is completed, the permeability of the soil is calculated by reading the water consumption scale on the measuring cylinder 5.
