Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0027] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

Abstract

The invention discloses an acid rain corrosion test device which comprises a rainfall system and a circulation system, the rainfall system comprises a rainfall assembly and a rainfall simulation box, and the rainfall assembly is arranged at the top of the rainfall simulation box; the water inlet end of the circulating system is communicated with the drain hole of the rainfall simulation box, and the water outlet end of the circulating system is communicated with the water inlet of the rainfall assembly. According to the acid rain corrosion test device provided by the invention, the rainfall system and the circulating system are matched to simulate a scene that acid rain corrodes rocks in a natural environment, so that the technical problem that the test result of an acid rain corrosion test in the prior art is inaccurate is solved.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to an acid rain corrosion test device. Background technique [0002] Under the influence of acid rain environment, corrosive damage and deformation occur on the rock surface, the internal pores increase, the permeability increases, and the strength and bearing capacity decrease, which leads to rock slope landslides, karst collapse, corrosion damage of cultural relics and ancient buildings, and structural damage of buildings . [0003] At present, in domestic and foreign researches on rock corrosion by acid rain, a single solution is generally used to soak rock samples. This test method not only wastes test materials, but also has low test efficiency and inaccurate test results. Contents of the invention [0004] The main purpose of the present invention is to provide an acid rain corrosion test device, aiming at solving the technical problem of inaccurate test re...
