Description
Technical field
Subgrade soils dry method and wet compaction test device are the utility model is related to, belongs to road construction experimental technique field.
Background technology
Traditional subgrade soils Indoor Impaction Test generally hits reality using dry method, i.e.,：Nature soil sample is first dried
It is dry, then different water cut proportioning, shelving are carried out, finally carry out hitting reality.In some damp-heat area surroundings weathers, soil property and hydrology bar
Part is complicated, and the state of subgrade soils interior humidity changes with the change in time and space, under the influence of local climate environment, after work
Roadbed soil's water content can be adopted subgrade soils close to a kind of equilibrium state that the conditions such as local climate, soil property, the hydrology are adapted
With the more close this equilibrium state of wet compaction test, also more meet engineering reality.During roadbed site operation, usual roadbed
Soil's water content is higher compared to optimum moisture content, thus it is more in the case of, need during subgrade construction using it from
The method for so air-drying or drying, makes the reduction of its moisture content, it is exactly such a simulation process that wet method, which is hit real,.According to conventional research
Achievement understands, dry method and wet method hit the construction moisture content at real obtained optimum moisture content and scene also there is certain area
Not.It is distinguished and the scope of application is studied, it appears it is particularly important that.Each result of the test is subjected to longitudinal contrast at the same time, with
Meet that the sample soil under equal conditions compares.
Utility model content
The purpose of this utility model is that devising subgrade soils dry method and wet compaction test device, pass through the experimental rig
Effectively the sample soil under equal conditions can be compacted or be heated, to improve the construction quality of subgrade soils.
To achieve the above object, the technical solution adopted in the utility model fills for subgrade soils dry method and wet compaction test
Put, which includes sample original soil mould 1, heating clay model tool 2, compacted soil mould 3, electric heating wire 4, driving motor 5, spiral shell
Bar 6, compacting base 7, contiguous block 8, compacting block 9, clump weight 10, spillway hole 11 and test stand 12；It is former to heat clay model tool 2, sample
