Description
Technical field
This utility model belongs to the test device technique field of rock sample moisture content.It is specifically related to the test device of rock sample moisture content under a kind of non-water-saturated state.
Background technology
The content of water has extremely important impact to physical-mechanical properties of rock, and the same rock of different water cut usually shows the physico mechanical characteristic of bigger difference.In Practical Project, rock intensity in dry conditions and hardness all meet engine request, and the phenomenon that after meeting water, rock strength substantially reduces is of common occurrence.On the one hand, water has certain cementation to rock particles, and the rock that especially argillaceous mineral are more is met water and softened, and directly affects deformation and the intensity property of rock；On the other hand, rock forming mineral granule can dissociate ion and molecule and water and other mineral generation chemical reactions in the case of meeting water, causes rock to be corroded and intensity reduction.
Studied by rock mechanics experiment: rock mechanics, Tunnel Engineering, underground chamber, rock slope engineering etc. are had great importance by the physical-mechanical properties of rock under different water cut.The method making saturated rock sample at present is more, such as natural bowssening, boiling method and vacuum saturation etc.；But it is mostly the rock sample preparation method of a certain moisture content of non-water-saturated state is the rock sample unknown by measuring multiple moisture content, thus select to meet the moisture content sample required, its uncertainty is bigger, inefficient, and the moisture content of rock sample is difficult to hold.
Utility model content
This utility model is intended to overcome above-mentioned technological deficiency, it is therefore an objective to provide a kind of simple in construction, the test device of rock sample moisture content under the non-water-saturated state that easy to operate, practical, precision is higher.
For achieving the above object, the technical solution adopted in the utility model is: described test device includes support, precision balance, Hanging Basket, beaker and mobile platform.
Support is made up of rectangular frame, top board and base plate；The upper and lower of rectangular frame is fixed with top board and base plate accordingly.Being provided with mobile platform on the base plate of support, mobile platform is made up of flat board, screw mandrel and base；The upper end of screw mandrel is fixed on the center position of flat board lower plane, and the lower end of screw mandrel is connected with whorl of base.The center position of top board has through hole, and top board is placed with precision balance, and the hook of precision balance is positioned at described through hole center, and Hanging Basket hangs on hook.
Beaker is placed on a mobile platform, and the bottom of Hanging Basket is positioned in beaker.
The centrage of the hook of precision balance, the bottom centre of Hanging Basket, the centrage of beaker and mobile platform is positioned on same plumb line.
Described Hanging Basket is made up of lanyard and chassis, and chassis is circular network structure；The diameter on chassis is less than the diameter of beaker.
The range of described precision balance is 2～3Kg, and precision is 0.01g.
Owing to using technique scheme, this utility model compared with prior art has the advantages that
1. simple in construction.This utility model is only made up of support, precision balance, Hanging Basket, beaker and mobile platform, and parts are mainly laboratory infrastructure device, and apparatus structure is simple.
The most easy to operate, practical.This utility model be easy to assemble and and dismounting, relate generally to balance weigh basic operation, provide new platform for the preparation of moisture content rock sample under non-water-saturated state, there is easy to operate, practical feature.
3. precision is higher.The precision balance that this utility model uses precision to be 0.01g weighs the quality of rock sample, uses distilled water immersion rock sample, and its rock sample moisture content precision made is higher.
Therefore, the feature that this utility model has simple in construction, easy to operate, practical and precision is higher, it is adaptable to meet the test of rock sample moisture content under water not disintegrate, insoluble and that drying shrinkage does not expands non-water-saturated state.
