Description

Technical Field

[0001] This invention relates to the field of erosion simulation testing of vegetation concrete, and in particular to an intelligent testing device for erosion resistance of vegetation concrete and its usage method. Background Technology

[0002] Vegetated concrete technology is widely used due to its advantages such as simple construction, high degree of mechanization, wide availability of materials, low cost, and good safety. Currently, research on the mechanical properties of vegetated concrete, substrate ratio, substrate fertility, and root-soil interaction is relatively mature, but research on its erosion resistance is less common. According to engineering experience, vegetated concrete can achieve good erosion resistance within a week after construction. However, in the early stages of construction, the hardening effect of the cement in the substrate has not yet been fully realized. If the surface becomes unstable under heavy rainfall or if large amounts of sediment erode, it can lead to soil and water loss on the slope, potentially causing serious safety hazards.

[0003] Current erosion resistance tests on vegetated concrete are relatively rudimentary and complex to operate. They also suffer from limited equipment options, cumbersome data recording, and mixed variable control procedures, failing to flexibly simulate different slopes (slope gradient, slope type) and incorporate local rainfall conditions. This results in significant discrepancies between measured data and actual conditions, and necessitates the fabrication of numerous molds when studying erosion under various scenarios, leading to a waste of materials and manpower.

[0004] In conclusion, it is essential to invent an intelligent testing device for erosion resistance of vegetation concrete that integrates scour material drying and weighing, which can flexibly simulate different local slope and rainfall conditions. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent testing device and method for testing the erosion resistance of vegetation concrete, which overcomes the limitations of traditional testing, is simple and convenient to operate and measure, and greatly simplifies the simulation steps, saving materials and manpower.

[0006] To achieve the above objectives, the present invention provides an intelligent testing device for erosion resistance of vegetated concrete, comprising a base frame, a rainfall simulation device, a turning slope, a mud and water collection box, and a mud and water drying and weighing integrated device. The mud and water drying and weighing integrated device is disposed on the base frame, the mud and water collection box is disposed on the top of the mud and water drying and weighing integrated device, the turning slope is disposed above the mud and water collection box, the rainfall simulation device is disposed above the turning slope, and the rainfall simulation device is connected to the base frame.

[0007] Preferably, the rainfall simulation device includes a rainfall nozzle, a water pipe, and a water storage tank. The rainfall nozzle is fixed directly above the turning slope by a strip support plate extending from the top of the base frame. One end of the water pipe is connected to the rainfall nozzle, and the other end of the water pipe passes through an intelligent rainfall control device fixed on the strip support plate and is connected to the water storage tank.

[0008] Preferably, the intelligent rainfall control device stores rainfall information from all over the country. By inputting the region name, the intelligent rainfall control device adjusts the pumping speed according to the input rainfall information, thereby simulating the effect of local rainfall eroding the slope.

[0009] Preferably, the bottom two sides of the base frame are used to place the water storage tank and the mud-water drying and weighing integrated device, respectively, and the middle part of the base frame is provided with two crossbeams for supporting the turning slope.

The slope control switch is equipped with a module selection knob for setting to a specific module and a slope angle knob for adjusting the rotation angle of the set module. The rotation angle range of the module is 0-90°, and various slope ratios can be simulated by adjusting every 10°.

[0011] Preferably, the module is a semi-open box structure, which is simulated and printed by a 3D printer to simulate the mainstream slope types in China, representing natural slopes and artificial slopes respectively. Natural slopes include erosion slopes, erosion slopes, and landslide slopes, while artificial slopes include road cut slopes, mine slopes, and fill slopes.

[0012] Preferably, the mud and water collection box is a semi-open box structure, which is located directly below the module and is used to collect the mud and water mixture washed down from the module.

The erosion modulus of the vegetation concrete was calculated to evaluate its erosion resistance.

[0019] In the formula: Q is the erosion modulus, C is the dry weight of the lost soil, A is the area of ​​the eroded surface, and T is time;

[0020] S5. Remove the mud and water collection box, clean out the dry soil inside, wash it with clean water, and prepare it for the next test.

After erosion is completed, turn on the power of the mud and water drying and weighing integrated device 6, turn on the drying control switch 605, dry the eroded mud and water, and record the numbers on the LED display 601 to obtain the dry soil mass. The dry soil mass is then calculated using the formula. Q represents the erosion modulus, C represents the dry weight of the lost soil (in g), A represents the area of ​​the eroded surface (in m²), and T represents the time (in min). The erosion modulus of the vegetation concrete is calculated to evaluate its erosion resistance.
