Embodiment

[0039] Such as figure 1 and figure 2 As shown, the present invention provides an artificial simulated rainfall device for full-scale model tests on slopes, which is mainly composed of a water supply system, a spray system, a movable support and a rainwater return system.

[0040] (1) Water supply system

[0041] The water supply system is mainly composed of two water storage barrels 1, a frequency conversion self-priming booster pump 2, a flow meter 3, a check valve 4, a joint 5, a main water pipe 6 and a water delivery pipe 21. The test rainwater is stored in two water storage barrels 1, which are connected by the water delivery pipe 21 and connected to the frequency conversion self-priming booster pump 2. After being pressurized, the rainwater passes through the flow meter 3, the check valve 4, and the union 5 in sequence, and then flows into the main water pipe. 6. Send the rainwater to the sprinkler system, such as image 3 shown.

Abstract

The invention discloses an artificial simulated rainfall device for a side slope full-scale model test. The device is mainly composed of a water supply system, a spraying system, a movable bracket anda rainwater backflow system. The water supply system is mainly used for providing power source, and adjusting pipeline pressure through a variable frequency self-priming pump at the same time; the spraying system generates simulated rainfall for the whole system, and simultaneously perform real-time monitoring for rainfall intensity through a rain gauge; the movable bracket is mainly used for keeping out natural rainfall, keeping out wind and collecting rainwater sprayed to the outside of a model box; and the backflow system is used for recycling the rainwater at a slope toe and the rainwatercollected by a rain curtain, thus, water cyclic utilization efficiency of the whole device is improved. The artificial simulated rainfall device for the side slope full-scale model test is convenientto operate, simple in structure, low-cost in manufacturing and environment-friendly can generate the artificial simulated rainfall highly similar to the natural rainfall, has a wide adjustable rain intensity range, and can provide technical assurance for carrying out the side slope full-scale model test and acquiring reliable test data.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering, and in particular relates to an artificial simulated rainfall device used for full-scale model tests of slopes. Background technique [0002] Rainfall is one of the main factors that induce landslides. To study the impact of rainfall on slope stability needs to be based on a large number of experimental data. However, the uncertainty of rainfall has brought great difficulties to the research work. In addition, the use of natural rainfall has a long research period and is greatly affected by the environment, so it is difficult to obtain ideal results. By artificially simulating rainfall, the experiment process can be conveniently controlled, the experiment cycle can be shortened, and the shortcomings of natural rainfall in the study of slope stability can be effectively overcome. [0003] Natural rainfall characteristics include rainfall intensity, uniformity of rainfall distribu...
