Description
Technical field
The present invention relates to the soil test field in a kind of civil engineering work subject, particularly one reinvents fine grained soil sample preparation device.
Background technology
When engineering investigation designs, reinventing the engineering characteristic such as physics, mechanics, infiltration of fine grained soil for obtaining saturated or unsaturation, needing to carry out shop experiment to remoulded sample.Manipulated soil dry density according to designing requirement in advance, can carry out correlation test to the same nature soil body, for engineering design and analytical calculation provide reliable basis.
At present, remolding soil specimens preparation mainly contains two kinds of methods: (1) compacting process: adopt the method for hammering soil sample layering to be hit real in required testing equipment, compacted soil samples is cut into the earth pillar being a bit larger tham cutting ring diameter, cutting ring vertical depression, limit flanging is whittled into sample, the method advantage is that sample preparation is simple, and shortcoming is that sample production is uneven, and dry density is wayward.(2) pressure-like method or hit sample method: wet soil sample is poured in pre-packed cutting ring, adopt the method for hitting reality or static pressure to prepare sample, the method advantage to obtain uniform sample, shortcoming is complex steps, especially the bad control of sample dry density, sample preparation size is restricted, fragile sample preparation cutting ring.
Retrieve widely for the problems referred to above, not yet find the associated solutions to this problem.
Summary of the invention
The object of the invention is exactly the shortcoming making poor, the complicated operation of controlling that sample exists in order to solve existing remolding soil specimens preparation facilities, and the one provided reinvents fine grained soil sample preparation device.
The technical solution used in the present invention:
One reinvents fine grained soil sample preparation device,
Reinvent fine grained soil sample preparation device, it is characterized in that comprising:
A, the reaction frame be made up of top board, lower platen and pull bar;
B, lower platen are arranged a sample preparation device be made up of cover plate, base and sample preparation cylinder, connect base bottom sample preparation cylinder, top connects cover plate, the inner cylinder face that cover plate is provided with column part and sample preparation cylinder forms being slidably matched of movement, cover plate lower surface connects permeable stone, sample preparation chamber is formed in sample preparation cylinder between cover plate lower surface and base, the sample preparation cutting ring arranged in sample preparation chamber coordinates with cover plate lower surface, the vent port be provided with in cover plate and permeable stone corresponding matching;
The sample preparation pressure apparatus that c, top board are arranged coordinates with cover plate mineralization pressure, and described sample preparation pressure apparatus can adopt the conventional device providing pressure such as hydraulic cylinder, hydropress, flypress.
On the basis of technique scheme, there is following further technical scheme:
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, first by sample preparation cylinder, base, cover plate, forms sample preparation chamber, is placed in by cutting ring in sample preparation chamber; Then according to designing manipulated soil dry density in advance, weighing wet soil sample and putting into sample preparation chamber, covering cover plate.Again sample preparation device is put into reaction frame, by load pressure device for sample preparation provides pressure.Last detaching device, obtains dissimilar soil test sample.In this device development process, easily form the empty van body closed after discovery fine grained soil, water and air potpourri contact with barrel, make gas in empty van be high pressure conditions when pressing down, sample is difficult to compacting, therefore this device is by cover plate perforate discharge sample preparation indoor gas; Simultaneously for ensureing that in sample preparation chamber, soil particle does not run off, and solves this problem by the method for upper berth filter paper, permeable stone.
The present invention has following beneficial effect: the invention solves remolding soil specimens make uneven, dry density is wayward and specimen size restricted problem.Can the dry density of effective Control Assay by this device, make sample smooth, meet the accuracy requirement of related specifications sample production, easy to operate, unload sample simple, make quick etc.This device advantage is, by the setting of filter paper, permeable stone, cover plate and vent port, to solve the exhausting problem in fine grained soil sample making course, and effectively protects sample preparation cutting ring and be not damaged.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
