Description
Technical field
The present invention relates to a kind of rainer, particularly 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 the rotation generation centrifugal acceleration by hydro-extractor pivoted arm, an artificial high gravity field is provided, the main body of research is set up to the model of certain guide, by centrifugal acceleration, increasing soil body gravity stress makes prototype and model reach ess-strain to equate, be out of shape similar, prototype is carried out to simulation test.Under stronger rainfall or continuous overcast and rainy effect, usually there is the landslide of all kinds and scale, the phenomenon of caving in soil-slope.The relation stable and rainfall of side slope is very close, in geotechnical centrifuge, side slope is studied in the working property under condition of raining, need to develop geotechnical centrifuge rainer.In the high centrifugal force field producing at geotechnical centrifuge, simulated rainfall can be subject to the hypergravity effect in centrifugal acceleration direction, thereby affects the serviceability of rainer.
Summary of the invention
The present invention provides a kind of geotechnical centrifuge rainer for solving the technical matters existing in known technology, this rainer is adapted at applying in strong centrifugal force field that geotechnical centrifuge produces, there is good serviceability and ease of use, can meet the requirement that realizes rainfall under geotechnical centrifuge environment.
The technical scheme that the present invention takes for the technical matters existing in solution known technology is: a kind of geotechnical centrifuge rainer, comprise the model casing that is positioned at bottom, at the top of described model casing, rainfall plate is installed, the bottom of described rainfall plate is porous plate, on described porous plate, convexes with cancelled structure; On described rainfall plate, be buckled with cover plate, described cover plate is sealed on described cancelled structure; Described rainfall plate is connected with described model casing by bolt with described cover plate; Between described porous plate and described cover plate, be formed with a plurality of rainfalls chamber, a plurality of atomizers are installed on described cover plate, the corresponding described atomizer in rainfall chamber described in each, described atomizer is arranged on the top center place of corresponding described rainfall chamber, and described in each, atomizer is all connected with water source.
Described in each, atomizer is connected with water source by connecting line is independent.
Described in each, on atomizer, be all connected with a water inlet pipe, be equipped with a valve described in each on water inlet pipe, described in each, water inlet pipe is all connected with described water source.
Described in each, on atomizer, be all connected with a water inlet pipe, all described water inlet pipes are connected with a water source by a feed pipe, are equipped with a valve described in each on water inlet pipe.
Advantage and good effect that the present invention has are: by atomizer, make water fogging, and it is indoor to be evenly sprayed at rainfall, can overcomes water problem pockety in high centrifugal field; Water falls into model casing by the porous plate of bottom, rainfall chamber, can guarantee that pilot region is realized uniform rainfall in model casing.Each atomizer is connected with water source by connecting line is independent, can in model casing, realize by the combinatory water supply mode of shower nozzle the rainfall of zones of different scope, by regulating the valve on water inlet pipe, can in model casing, realize the rainfall of varying strength.The present invention innovates by mechanism, can avoid the impact on rainfall of high centrifugal field that geotechnical centrifuge produces, and simple in structure, easy to operate.
