Description
Technical field
The present invention relates to the soil test field in a kind of civil engineering work subject, particularly a kind of fine grained soil sample preparation device of reinventing.
Background technology
When engineering investigation designs, reinvent the engineering characteristic such as physics, mechanics, infiltration of fine grained soil for obtaining saturated or unsaturation, need to carry out shop experiment to remoulded sample.The manipulated soil dry density can be carried out correlation test to the same nature soil body according in advance designing requirement, for engineering design and analytical calculation provide reliable basis.
At present, the remolding soil specimens preparation mainly contains two kinds of methods: (1) compacting process: adopt the method for hammering the soil sample layering to be hit real to required testing equipment, compacted soil samples is cut into the earth pillar that is a bit larger tham the cutting ring diameter, the cutting ring vertical depression, the limit flanging is whittled into sample, the method advantage is that sample preparation is simple, and shortcoming is that sample production is inhomogeneous, and dry density is wayward.(2) press sample method or hit the sample method: the wet soil sample is poured in the pre-packed cutting ring, adopted the method for hitting reality or static pressure to prepare sample, the method advantage is to obtain even sample, shortcoming is complex steps, especially the bad control of sample dry density, the sample preparation size is restricted, fragile sample preparation cutting ring.
Retrieve widely for the problems referred to above, not yet find the relevant solution to this problem.
Summary of the invention
The object of the invention is exactly the shortcoming for controlled poor, the complicated operation that solves that existing remolding soil specimens preparation facilities makes that sample exists, a kind of fine grained soil sample preparation device of reinventing that provides.
The technical solution used in the present invention:
A kind of fine grained soil sample preparation device of reinventing,
Reinvent the fine grained soil sample preparation device, it is characterized in that comprising:
A, the reaction frame that is formed by top board, lower platen and pull bar;
A sample preparation device that is comprised of cover plate, base and sample preparation cylinder is set on b, the lower platen, sample preparation cylinder bottom connects base, top connects cover plate, the inner cylinder face that cover plate is provided with column part and sample preparation cylinder forms being slidingly matched of piston form, the cover plate lower surface connects permeable stone, form sample preparation chamber in the sample preparation cylinder between cover plate lower surface and the base, the sample preparation cutting ring that arranges in the sample preparation chamber cooperates with the cover plate lower surface, the vent port that is provided with in the cover plate and permeable stone corresponding matching;
The sample preparation pressure apparatus that arranges on c, the top board cooperates with the cover plate mineralization pressure, and described sample preparation pressure apparatus can adopt the routines such as hydraulic cylinder, hydropress, flypress that the device of pressure is provided.
On the basis of technique scheme, following further technical scheme is arranged:
Between permeable stone and sample preparation cutting ring, be provided with filter paper, be embedded in the recess of cover plate lower surface at permeable stone.
The present invention forms sample preparation chamber at first by sample preparation cylinder, base, cover plate, and cutting ring is placed in the sample preparation chamber; Then according to designing the manipulated soil dry density in advance, weighing wet soil sample is put into sample preparation chamber, covers cover plate.Again sample preparation device is put into reaction frame, provide pressure by the load pressure device for the sample preparation.Last detaching device obtains dissimilar soil test samples.In this device development process, easily form the empty van body of sealing after discovery fine grained soil, water and air potpourri contact with barrel, so that the interior gas of empty van is high pressure conditions, sample is difficult to compacting, so this device is discharged the sample preparation indoor gas by the cover plate perforate when pressing down; Simultaneously for guaranteeing that soil particle does not run off in the sample preparation chamber, the method by upper berth filter paper, permeable stone addresses this problem.
The present invention has following beneficial effect: the invention solves remolding soil specimens make inhomogeneous, dry density is wayward and specimen size restricted problem.By the effective dry density of Control Assay of this device, it is smooth to make sample, satisfies the accuracy requirement of related specifications sample production, and easy to operate, it is simple to unload sample, makes quick etc.This device advantage is the setting by filter paper, permeable stone, cover plate and vent port, has solved the exhausting problem in the fine grained soil sample making course, and has effectively protected the sample preparation cutting ring not to be damaged.
