Description
Technical field
The invention belongs to earthwork test Instrument attachmentes, and three axis of modified ess-strain formula is used for more particularly to one kind
The opposite opened of instrument holds film cylinder.
Background technology
It is the indispensable attachment for sealing sample and sealing sample transfer being installed on to triaxial apparatus to hold film cylinder.
The existing film cylinder that holds is the integrated member that a kind of cylinder cannot be split, and composition includes cylinder, cylinder middle part gas
The stomata of slot intersection and the vacuum noz(zle) for being connected to stomata.
It holds film cylinder at work, the air held in film cylinder is extracted by air intake duct by rubber pipette bulb first, makes device in cylinder
Smooth being attached at of tubular latex mould hold film cylinder inner wall, the sample being set on supporting plate simultaneously makes the tight Shu Yu of tubular latex mould
Then sample is moved on the lower porous disc of triaxial apparatus mounting base and seals sample, it is last vertical above carry hold film cylinder disengage it from
Triaxial apparatus, the effect for so far holding film cylinder are completed.
It is existing hold film cylinder there are the problem of be due to metal material and the performance that can not be split, hold very much in working condition
Easily there is sealing sample and hold during film cylinder departs from triaxial apparatus to be not tight seal, damage sample, should not clean etc. and to ask
Topic.Moreover, the existing film cylinder that holds is comparatively laborious in the operating procedure of suit sample and sealing sample, easily disturbs sample and influence reality
The precision tested.
Split cavity avoids the soil body disturbed for holding after film cylinder removes when holding lotus cap at the top of dress soil sample.
The content of the invention
The purpose of the present invention is disclosing a kind of pumping type opposite opened for modified ess-strain formula triaxial apparatus to hold film cylinder,
This opposite opened holds that film cylinder has the characteristics that carry air extractor and cylinder can be split.
The present invention includes cylinder, hangers, nut, bolt, piston, exhaust tube, pitch brace, draw ring, hinge and sealing
Adhesive tape, cylinder include left semicircle cylinder and right semi-circle cylinder, pass through conjunction between left semicircle cylinder and right semi-circle cylinder one side
Page is hinged, left semicircle cylinder and right semi-circle cylinder be respectively provided with hangers, left semicircle cylinder and right semi-circle cylinder opposite side by hangers,
Screw bolt and nut is combined together, and the docking section of left semicircle cylinder and right semi-circle cylinder, which is equipped with positioning spigot and is embedded in positioning, stops
The sealing joint strip of port recess；The inner wall of cylinder has air drain, the horizontal and vertical distribution of air drain, horizontal air drain and longitudinal gas
Slot is interconnected, and the air drain of cylinder offers stomata, and stomata is connected with air drain, and with being connected outside stomata, piston is drawn exhaust tube
The forepart of bar has piston, and the rear portion of pitch brace has draw ring, and piston and pitch brace are located in exhaust tube.
The course of work of the present invention：
Left semicircle cylinder and right semi-circle cylinder inner surface are evenly distributed with the longitudinal air drain communicated and horizontal air drain, tubular
Rubber membrane is placed in opposite opened and holds in film cylinder, and rubber membrane both ends, which overturn and are closely set in, originally holds film cylinder both ends, holds on the outside of film cylinder
Respectively suit one tightens cushion rubber for lower end.Piston is controlled using draw ring, pumping can be realized and attach latex film.
Beneficial effects of the present invention：
Originally the cylinder for holding film cylinder is made of the docking of two halves cylinder, and is made and closed by hangers and its fixedly connected part
Close and split two states.The two halves cylinder being connected to one have it is existing hold film cylinder include vertically and horizontally air drain, gas
Hole and the design feature of exhaust tube, thus seal sample and transfer sample various configurations and application method hold film cylinder with existing
It is identical.After this opposite opened of disassembled form holds film cylinder for sample to be installed on improved triaxial apparatus, split cavity can be replaced, is torn open
Divide the fixedly connected part that hangers is only unclamped in operation can be easily by two halves cylinder and triaxial apparatus disengaging.It is and convenient clear
It washes.The present invention has simple and reasonable and easy to use outstanding advantages.
