Abstract
A kind of coarse granule frozen soil holds, retentiveness testing equipment, can effectively measure coarse-grained soil and hold aqueous and retentiveness, provides advantageous data for the theoretical calculation of soil body pore volume and analysis and supports.It include sample bucket and transparent pressure-measuring pipe, sample bucket have upper end opening, be provided with straight-through valve water inlet straight tube, water outlet straight tube be respectively fixedly disposed at one side lower part of sample bucket and another side bottom, be connected with sample bucket internal cavities.The axis of the transparent pressure-measuring pipe is L-shape, and horizontal segment port is connect with being discharged the water outlet of straight tube, erects the upper end opening that section port is higher than sample bucket.
Description
Technical field
The utility model is related to technical field of civil engineering, more particularly to a kind of coarse granule frozen soil holds, retentiveness experiment is set
It is standby
Background technology
Specific specification is had not yet been formed to aqueous and retentiveness the experimental study of appearance of the soil body both at home and abroad at present, there are no rule
Appearance that the unified testing equipment of model measures the soil body is aqueous, retentiveness.It is therefore, it is necessary to aqueous and retentiveness according to holding for the soil body
Basic conception develops a set of measure coarse-grained soil that is suitable for and holds aqueous and retentiveness testing equipment, is soil body pore volume
Theoretical calculation and analysis provide advantageous data and support.
Utility model content
Hold the technical problem to be solved by the utility model is to provide a kind of coarse granule frozen soil, retentiveness testing equipment, it can
It effectively measures coarse-grained soil and holds aqueous and retentiveness, advantageous data are provided for the theoretical calculation of soil body pore volume and analysis
It supports.
Technical solution is as follows used by the utility model solves its technical problem：
A kind of coarse granule frozen soil of the utility model holds, retentiveness testing equipment, it is characterized in that：It is including sample bucket and thoroughly
Bright pressure-measuring pipe, sample bucket have upper end opening, are provided with the water inlet straight tube of straight-through valve, water outlet straight tube is respectively fixedly disposed at
One side lower part of sample bucket and another side bottom are connected with sample bucket internal cavities；The axis of the transparent pressure-measuring pipe is L-shape,
Its horizontal segment port is connect with being discharged the water outlet of straight tube, erects the upper end opening that section port is higher than sample bucket.
The beneficial effects of the utility model are can effectively to measure coarse-grained soil to hold aqueous and retentiveness, are soil body pore-body
Long-pending theoretical calculation and analysis provides advantageous data and supports, is suitable for coarse-grained soil appearance, the water holding of maximum particle diameter≤30mm
Property experiment.It is simple in structure, it is easy to operate.
Description of the drawings
This specification includes such as next width attached drawing：
Fig. 1 is a kind of coarse granule frozen soil appearance of the utility model, retentiveness testing equipment；
Component and corresponding label are shown in figure：Sample bucket 10, water inlet straight tube 11, water outlet straight tube 12, transparent pressure-measuring pipe 13.
Specific embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
With reference to Fig. 1, a kind of coarse granule frozen soil of the utility model holds, retentiveness testing equipment includes sample bucket 10 and transparent
Pressure-measuring pipe 13, sample bucket 10 have upper end opening, are provided with the water inlet straight tube 11 of straight-through valve, water outlet straight tube 12 is fixed respectively
10 1 side lower part of sample bucket and another side bottom are arranged on, is connected with 10 internal cavities of sample bucket.The transparent pressure-measuring pipe 13
Axis it is L-shape, horizontal segment port connect with being discharged the water outlet of straight tube 12, erects the upper end of section port higher than sample bucket 10
Opening.
10 headroom geometric dimension of sample bucket is generally：Diameter × height=300mm × 200mm, experiment frozen soil sample are maximum
Permission grain size is 30mm.
The above only explain through diagrams a kind of coarse granule frozen soil of the utility model hold, retentiveness testing equipment some
Principle, be not intended to by the utility model be confined to shown in and the concrete structure and the scope of application in, therefore it is every it is all can
The corresponding modification that can be utilized and equivalent, belong to the apllied the scope of the claims of the utility model.
