Embodiment 1

[0065] Comply with the above technical solutions, such as Figure 1 to Figure 8 As shown, the present embodiment provides a soil slope slope model scour test device, including a test box 1, and also includes a model box 2 and a loading device 3 installed in the test box 1, the test box Rainfall device 4 is also installed in 1;

[0066] One side of the model box 2 is hinged with the test box body 1 . The other end of the hinge of the model box 2 and the test box body 1 is also equipped with a reaction force plate 5, and a model box angle changing device 6 is also connected between the described reaction force plate 5 and the test box body 1. The model box angle changing device 6 is used to lift the side of the model box 2 where the reaction force plate 5 is installed. The rainfall device 4 is used to scour the model soil in the model box 2, the loading device 3 is used to compact the model soil in the model box 2, one side of the model box 2 is hinged with the test box 1, and...

Embodiment 2

[0088] A method for making a soil slope surface model, the method is carried out by the described device for making a soil slope surface model and scouring test, and the method includes the following steps:

[0089] Step 1: Calculate the amount of soil required to achieve the required compaction degree of the test;

[0090] Firstly, the maximum dry density ρ of the test soil was obtained through the indoor compaction test max , according to the degree of compaction required by the test, combined with the maximum dry density of the test soil, the bottom area S of the model box 2 and the thickness h of the slope model to calculate the amount of soil required to make a slope model;

[0091] Step 2: Filling and compacting successively;

[0092] The soil retaining plate 11 is installed in the retaining plate retaining groove 10, since the distance between the retaining plate retaining grooves 10 is equal, the soil mass weighed according to the amount of soil required for the test ...

Embodiment 3

[0096] A soil slope surface model, prepared by the method in Embodiment 2 of the soil slope surface model. The slope surface model is made by the pressure loading device and the model box, which can accurately ensure the compaction of the slope surface model, avoid the use of large earthwork volumes, shorten the test period, and save the test capital and manpower consumption;

Abstract

The invention provides a soil slope surface model manufacturing and scouring test device which comprises a test box body, and further comprises a model box and a loading device which are mounted in the test box body, and a rainfall device is further mounted in the test box body. One side of the model box is hinged to the test box body, the other end of the model box, which is hinged to the test box body, is also provided with a counter-force plate, and a model box angle changing device is also connected between the counter-force plate and the test box body. A slope surface model is manufactured through the pressure loading device and the model box, the compactness of the slope surface model can be accurately guaranteed, the use of a large amount of earthwork is avoided, the test period isshortened, and the capital and manpower consumption of the test is saved; and the inclination angle of the model box can be adjusted through the model box angle changing device, and the test requirements of slopes with different inclination angles can be met. The rainfall intensity, the rainfall duration and the rainfall type can be adjusted through a rainfall flow control device, and slope rainfall erosion tests with different rainfall parameters can be achieved.

Description

technical field [0001] The invention belongs to the technical field of geotechnical model experiments, and in particular relates to a soil slope surface model, a manufacturing method, a scour test device and a method. Background technique [0002] With the rapid development of our country's economy and the vigorous advancement of infrastructure construction, there are a large number of soil slopes in the construction of major projects such as highways and railways, ditch control land reclamation, and flat mountain construction. Under the interference of factors such as short-term heavy rainfall and continuous rainfall, the bare slope surface is prone to soil instability, which will cause shallow slope diseases such as erosion, spalling, and gullies, and even further cause The overall instability of the slope. [0003] A large number of scholars at home and abroad have studied the characteristics of slope erosion damage, and have developed many slope protection materials wit...
