Problems solved by technology

The traditional indoor rainfall infiltration test device is mainly designed for a specific one or several items to be studied. For example, the device can only study the rainfall infiltration on the plane or the pressure infiltration under a constant water head. The corresponding The test device cannot be widely used
In addition, the traditional rainfall infiltration test device mainly simulates seepage under heavy rainfall, and the simulation under light rain is insufficient.

Abstract

The invention discloses an indoor rainfall infiltration test simulation system. The indoor rainfall infiltration test simulation system comprises a support, an indoor rainfall simulation system, a soil slope seepage simulation system and a measuring system; the indoor rainfall simulation system comprises a base, a bracket and a test trough, and a soil groove, a bottom seepage collection groove, a side seepage collection groove and a runoff collection groove are formed in the test trough; the base is provided with a hinge support and a pin support, the hinge support is connected with the base in a sliding manner, the support is provided with pin holes which are sequentially distributed from bottom to top, and the hinge support is fixedly connected with the base; the test trough is fixed on the bracket, and one side, which is provided with the runoff collection groove, of the test trough is adjacent to the hinge support. By adopting the indoor rainfall infiltration test simulation system, a water transfer form and a variation rule of various physical quantities in the rainfall infiltration process in different soil textures under different slopes and different rainfall intensities can be researched.

Description

technical field [0001] The invention relates to a rainfall infiltration research test device, in particular to an indoor rainfall infiltration test simulation system. Background technique [0002] The indoor rainfall infiltration test device is a basic tool for the study of rainfall infiltration. The infiltration test device is used to study the migration form of artificial rainfall in the medium, the change of matrix suction during the water migration process, the change of infiltration rate, and the rainfall infiltration. Changes in infiltration, rainfall runoff, rainfall infiltration and infiltration rate. The traditional indoor rainfall infiltration test device is mainly designed for a specific one or several items to be studied. For example, the device can only study the rainfall infiltration on the plane or the pressure infiltration under a constant water head. The corresponding The test device cannot be widely used. In addition, the traditional rainfall infiltration...
