Description

Technical Field

[0001] This utility model relates to the field of agricultural production engineering, and in particular to a device for detecting the erosion resistance of channel slopes in saline-alkali soil areas. Background Technology

[0002] The soil salinization in western Jilin Province, my country, is severe, significantly impacting local agriculture and industry. Currently, there is no comprehensive testing system for canal lining projects using saline soil from western Jilin for soil solidification, and there is a limited availability of machinery for testing the erosion resistance of solidified saline soil canals. In my country's agricultural water conservancy construction, canal erosion resistance testing technology is crucial, providing essential reference data for efficient quality assessment of canal projects. Its convenience and ability to simulate various working conditions have promoted the development of the irrigation industry. However, the limitations of traditional erosion resistance testing techniques, primarily applicable to high-strength materials like concrete, prevent its application in the solidified soil field. Utility Model Content

[0003] The purpose of this invention is to provide a soil erosion resistance testing device for channel slopes in saline-alkali soil areas to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A device for testing the erosion resistance of channel slopes in saline-alkali soil areas includes a housing, a spraying device, an erosion bearing device, and a clamping device. The housing comprises a water storage chamber, a immersion test chamber, and an erosion test chamber. The immersion test chamber is located to the left of the water storage chamber. The erosion test chamber is located above the immersion test chamber. A flow controller is installed on the spraying device. The spraying device is mounted above the erosion test chamber. The water storage chamber is connected to the spraying device via a first water pump and a first pipeline. The erosion bearing device... The device is installed inside the scouring test chamber and located below the spraying device. The scouring support device includes a tray, a slope adjustment component, and a soil collection trough. The right end of the tray is rotatably connected to the scouring test chamber, and the left end is installed inside the scouring test chamber via the slope adjustment component. A water outlet is provided on the right side of the tray. The soil collection trough is connected to the right end of the tray. The bottom of the soil collection trough is a screen. The clamping device is installed inside the immersion test chamber and is used to clamp the sample. The water storage chamber is connected to the immersion test chamber via a second water pump and a second pipeline.

[0006] In a further description of the present invention, the slope adjustment assembly includes a sleeve and an adjustment rod; the lower end of the sleeve is rotatably connected to the immersion test chamber; the adjustment rod is telescopically adjustable and installed inside the sleeve, and its end is fixedly connected to the tray.

[0007] In a further description of this utility model, the soil collection trough is fixed to the upper part of the immersion test chamber; the upper right end of the soil collection trough extends into the flushing test chamber and connects with the right end of the tray.

[0008] As further described in this utility model, the bottom of the flushing test chamber is provided with several water leakage holes.

[0009] In a further description of the present invention, the clamping device includes two sets of telescopic adjusting rods and a pressure plate; the two sets of telescopic adjusting rods are installed left and right in the immersion test chamber and their ends are connected to the pressure plate for controlling the lifting and lowering of the pressure plate.

[0010] In a further description of this utility model, the bottom of the immersion test chamber is provided with a drain outlet; a rubber plug is installed in the drain outlet.

[0011] The beneficial effects of this utility model are as follows:

[0012] This design features two testing modes: rainfall erosion test and immersion test. For the rainfall erosion test, the tray's inclination is adjusted using the slope adjustment component, and the spray flow rate is controlled by the flow controller. The pre-prepared sample is placed in the tray, the water pump is activated, and water is supplied from the storage chamber to the spraying device. The water is then sprayed into the test chamber to simulate rainfall erosion. Water from the tray flows through the outlet into the soil collection trough, where it is filtered by a screen at the bottom to separate soil particles. The water then flows downwards into the immersion test chamber. After the rainfall erosion is complete, soil samples that entered the collection trough are collected. This testing mode can simulate the erosion resistance of soil under different slopes and rainfall levels. For the immersion test, compacted soil blocks are placed in the immersion test chamber and clamped in place. After soaking for a set time, the blocks are removed, and particle collection is performed. Therefore, this design can simulate the performance testing of solidified soil under different environments and with different water ingress times, providing a reliable reference for construction quality testing.

The erosion test chamber 13 is located above the immersion test chamber 12. A flow controller 21 is installed on the spraying device 2. The spraying device 2 is mounted above the erosion test chamber 13. The water storage chamber 11... Chamber 11 is connected to spraying device 2 via first water pump 5 and first pipe 6; the scouring bearing device 3 is installed inside scouring test chamber 13 and located below spraying device 2; the scouring bearing device 3 includes tray 31, slope adjustment component 32, and soil collection trough 33; the right end of tray 31 is rotatably connected to scouring test chamber 13, and the left end is installed inside scouring test chamber 13 via slope adjustment component 32; a water outlet is provided on the right side of tray 31; the soil collection trough 33 is connected to the right end of tray 31; the soil collection... The bottom of the trough 33 is a sieve 331; the clamping device 4 is installed in the immersion test chamber 12 for clamping the sample; the water storage chamber 11 is connected to the immersion test chamber 12 via the second water pump 7 and the second pipe 8; this design has two testing modes: rainfall erosion test and immersion test. When the erosion test is required, the inclination of the tray 31 is adjusted according to the testing requirements by the slope adjustment component 32, the spray flow rate is controlled by the flow controller 21, the pre-prepared sample is placed in the tray 31, the water pump is started, and the water storage chamber 12 is filled with water. Water is supplied to the spraying device 2 and sprayed out to simulate rainfall erosion in the test. The water in the tray 31 flows into the soil collection tank 33 through the outlet and is filtered by the screen 331 at the bottom of the soil collection tank 33 to isolate soil particles. The water then flows down into the immersion test chamber 12. After the erosion is completed, the soil sample that entered the soil collection tank 33 during the erosion is collected. The collected soil sample is dried to ensure that the moisture in the soil sample is completely evaporated in order to obtain an accurate soil sample mass. The mass of the dried soil sample is weighed and the data is recorded. Based on the collected data, the erosion resistance of the soil samples is analyzed. This test mode can simulate the erosion resistance of soil under different slopes and rainfall conditions. When a water immersion test is required, the compacted soil block is placed in the water immersion test chamber 12 and clamped and positioned by the clamping device 4. Water is pumped from the water storage chamber 11 to the water immersion test chamber 12 by the second water pump 7 until the soil block sample is submerged. After soaking for a set time, the sample is removed and the particles are collected and tested. Therefore, this design can simulate the performance testing of solidified soil under different environments.

[0016] The slope adjustment component 32 includes a sleeve 321 and an adjusting rod 322; the lower end of the sleeve 321 is rotatably connected to the immersion test chamber 12; the adjusting rod 322 is telescopically adjustable and installed inside the sleeve 321, and its end is fixedly connected to the tray 31.

After applying a certain pressure manually, the extension and retraction of the adjusting rod 322 can be controlled.

[0017] In this design, the soil collection trough 33 is fixed in the upper part of the immersion test chamber 12; the upper right end of the soil collection trough 33 extends into the flushing test chamber 13 and connects with the right end of the tray 31, ensuring that the soil collection trough 33 can collect the water flowing down from the tray 31. After being filtered by the screen 331, the water flows down to the immersion test chamber 12, avoiding water accumulation and water waste.

[0018] The bottom of the flushing test chamber 13 is provided with several drainage holes 131, so that the water inside the flushing test chamber 13 can also fall into the immersion test chamber 12 through the drainage holes 131, thus avoiding water accumulation in the flushing test chamber 13 and affecting its detection.

[0019] The clamping device 4 includes two sets of telescopic adjustment rods 41 and a pressure plate 42. The two sets of telescopic adjustment rods 41 are installed in the immersion test chamber 12 on the left and right sides and their ends are connected to the pressure plate 42. They are used to control the lifting and lowering of the pressure plate 42. After compaction, the soil block sample is placed in the immersion test chamber 12 and then pushed under the pressure plate 42. Then, pressure is applied to the pressure plate 42 downward, causing the telescopic adjustment rods 41 to retract until the pressure plate 42 presses against the soil block sample to fix the soil block test.

[0020] The bottom of the immersion test chamber 12 is provided with a drain outlet 121; a rubber stopper is installed in the drain outlet 121, and the water in the immersion test chamber 12 can be drained by removing the rubber stopper.
