The utility model has a good airtightness, can be used for testing various parameters of one soil sample; is low in experiment cost, can collect the water discharged during the process of the solidification and sedimentation of the soil sample, and is used for studying water absorbing rule during the unloading and the resilience of the soil sample.
Description
Technical field
The utility model relates to the experimental provision of measuring the fixed usefulness of soil body penetration, especially relates to a kind of experiment container of measuring the fixed usefulness of soil body penetration.
Background technology
If utilize the osmotic coefficient k of the soil sample that permeameter measures inconsistent with the actual forced status at scene in the laboratory, it measures the result can have very large deviation with actual conditions; Though the geotechnique that traditional consolidometer carries out experiment can be satisfied requirement of engineering, will carry out more intensive research for the consolidation characteristics of soft clay but has tangible deficiency.Through document and patent retrieval, find that existing scholar transforms the fixed experimental provision of tradition, but main thought is the measurement to pore water pressure.Because the sealing problem of infiltration consolidation container is still unresolved in the experimental provision, can not the pore water that soil sample in the process of consolidation is extruded be collected, and causes some experimental projects to carry out, and has influenced the deformation characteristic and the mechanism of more deep research soft clay.
Summary of the invention
The purpose of the utility model is to provide the experiment container of a kind of good airproof performance, the fixed usefulness of the more cost effective mensuration soil body penetration of experimental cost.
For realizing above-mentioned purpose, the utility model can be taked following technical proposals:
The experiment container of the fixed usefulness of the described mensuration soil body penetration of the utility model; Comprise and have the base that encircles platform, be arranged on inner core in the base ring platform and the pressurizing piston that moves up and down along the inner core inwall; Said base, inner core and pressurizing piston three surround a cavity that holds soil sample; The annular faying face of said inner core and base is provided with O-ring seal, and the outer wall of said inner core is provided with presents a theatrical performance as the last item on a programme, and the fastening screw latch closure that is screwed on the base ring platform is pressed on said the presenting a theatrical performance as the last item on a programme; Offer the twice U-lag on the outer wall of said pressurizing piston, be placed with O-ring seals in it, offer osculum and the vent port that is connected with the cavity that holds soil sample at the top of pressurizing piston; Extend in the cavity that holds soil sample from the bottom of base with the joining passage of external valve.
Offer annular groove on the bottom surface of said inner core, said O-ring seal is arranged in the said annular groove.
The top of said pressurizing piston is a concave panel.
Be respectively arranged with the permeable stone layer on the susceptor surface that said inner core ring encloses and the bottom surface of pressurizing piston.
The bottom surface middle part of said base is provided with locating slot.
The advantage applies of the utility model is in the following aspects:
1, the good airproof performance of experiment container can guarantee that the minor amount of water of from soil sample, discharging can be collected fully;
2, can carry out the infiltration coefficient under the different loads effect to same soil sample, the parameter that obtains is many, and soil sample is fully used, and is reasonable more economically on experimental cost;
3, can measure the distortion of sample, the dissipation of bottom interstitial hydraulic pressure, can collect the water yield that soil sample is discharged in process of consolidation, so that the suction rule during research soil sample off-load resilience.
