Description
Technical field
The present invention relates to a kind of rainer, particularly to a kind of geotechnical centrifuge rainer.
Background technology
Geotechnical centrifuge is a kind of testing equipment for Geotechnical Engineering physical simulation experiment.Its ultimate principle is by centrifugal
The rotation of machine pivoted arm produces centrifugal acceleration, it is provided that an artificial high gravitational field, and the main body of research is set up a definite proportion chi
Model, by centrifugal acceleration increase soil body weight stress, prototype is reached ess-strain is equal, it is similar to deform with model,
Prototype is simulated test.Soil-slope is under stronger rainfall or continuously overcast and rainy effect, it occur frequently that various types of
Type and the landslide of scale, phenomenon of caving in.The relation of the stable and rainfall of side slope is very close, opposite side in geotechnical centrifuge
Slope working property under condition of raining is studied, and needs to develop geotechnical centrifuge rainer.Produce at geotechnical centrifuge
In raw high centrifugal force field, simulated rainfall by the hypergravity effect on centrifugal acceleration direction, thus can affect rainfall dress
The service behaviour put.
Summary of the invention
The present invention solves that technical problem present in known technology provides a kind of geotechnical centrifuge rainer, this rainfall
Device is suitable for applying in the strong centrifugal force field that geotechnical centrifuge produces, and has excellent service behaviour and ease of use,
Disclosure satisfy that the requirement realizing rainfall under geotechnical centrifuge environment.
The present invention solves that technical problem is adopted the technical scheme that present in known technology: a kind of geotechnical centrifuge fall
Rain device, including the model casing bottom being positioned at, is provided with rainfall plate, the end of described rainfall plate at the top of described model casing
Portion is porous plate, is convexly equipped with cancelled structure on described porous plate；Being buckled with cover plate on described rainfall plate, described cover plate covers
On described cancelled structure；Described rainfall plate and described cover plate are connected with described model casing by bolt；At described porous plate
And it is formed with multiple rainfall room between described cover plate, described cover plate is provided with multiple atomizer, each described rainfall
The corresponding described atomizer in room, described atomizer is arranged at the top center of corresponding described rainfall room, Mei Gesuo
State atomizer to be all connected with water source.
Each described atomizer is connected with water source by connecting line is independent.
It is respectively connected with a water inlet pipe on each described atomizer, each described water inlet pipe is equipped with a valve, often
Individual described water inlet pipe is all connected with described water source.
Being respectively connected with a water inlet pipe on each described atomizer, all described water inlet pipes pass through a feed pipe and a water
Source is connected, and each described water inlet pipe is equipped with a valve.
The present invention has the advantage that with good effect: made water fogging by atomizer, and it is indoor to be uniformly sprayed at rainfall,
Water problem pockety in high centrifugal field can be overcome；Water falls into model casing by the porous plate bottom rainfall room, can
Ensure that pilot region realizes uniform rainfall in model casing.Each atomizer is connected with water source by connecting line is independent,
The rainfall of zones of different scope can be realized in model casing, by regulation water inlet pipe by the combinatory water supply mode of shower nozzle
Valve, the rainfall of varying strength can be realized in model casing.The present invention passes through mechanics innovation, it is possible to avoid geotechnique centrifugal
The high centrifugal field that machine the produces impact on rainfall, and simple in construction, easy to operate.
