Problems solved by technology

[0005] Purpose of the invention: Aiming at the problem that traditional indoor small and medium-sized rainfall simulation devices cannot accurately simulate low rainfall intensity and that rainwater mainly flows down from the side wall of the model test box and produces a large boundary effect when the rainfall intensity is high, the present invention proposes a method that can better simulate Rainfall simulation device for indoor landslide physical model test to avoid rainfall impact and scattered water spray side wall concentration phenomenon under low rainfall intensity

Abstract

The invention discloses a rainfall simulation device for an indoor landslide physical model test. The device comprises a fixed truss, a box body, a box body top water injection pipe orifice, a box body water injection and distribution structure, a box body bottom array nozzle structure, a water injection pipeline and a rain intensity control system, except for the bottom array nozzle structure, the box body is of a closed structure, a water source is a pressure tap water pipe which can be seen everywhere in a laboratory, the defect that an existing rainfall simulation device cannot simulate light rainfall intensity uniform rainfall is overcome, and the rainfall simulation device can be used for rainfall simulation of indoor small and medium-sized landslide physical model tests.

Description

technical field [0001] The invention belongs to the technical field of indoor rainfall simulation, in particular to a rainfall simulation device for indoor landslide physical model tests. Background technique [0002] Landslides are the main type of common geological disasters, which are extremely harmful to people's lives and property safety. In the southwestern region of my country, especially in the southwestern hilly areas, there are many mountains, steep mountains, loose soil structure, easy to accumulate water, and valleys and rivers are all over the mountains, cutting each other, thus forming many slopes with enough sliding space and cut surfaces. The basic conditions for landslides to occur widely exist, and landslide disasters are quite frequent. Moreover, since the 21st century, my country has built many water conservancy projects in the southwest region, so the research on landslides involved in water conservancy projects has great engineering significance.
