Abstract
The utility model relates to a broken rock and unconsolidated porosint infiltration testing additional equipment matched with the MTS815 and the MTS816 series of rock mechanics testing systems, consisting of a piston (1), a cylinder (2), a filter pad (3), a perforated plate (4) and a junction panel (5). The equipment is arranged in an axial loading apparatus of the rock mechanics testing system and can carry out the transient-state and the steady-state permeation tests of broken rocks and unconsolidated porosint, and can do compression tests of the materials; hereby the functions of the rock mechanics testing system can be expanded.
Description
One, technical field
The utility model relates to rock-soil material mechanical property test field, specifically a kind of matching used with MTS815 and 816 serial rock mechanics testing systems, the attachment device that is used for fractured rock and non-fixed porosint permeability test, make this rock mechanics testing system can carry out the transient state and the steady-state permeation test of fractured rock and non-fixed porosint, the double simultaneously compression test of doing these materials is expanded its function.
Two, background technology
At present, do not see as yet in the domestic and foreign literature about carry out the report of fractured rock and non-fixed porosint permeability test on MTS815 and 816 serial rock mechanics testing systems, the production firm of this rock mechanics testing system does not provide the attachment device of fractured rock and non-fixed porosint permeability test yet.This rock mechanics testing system can only carry out the transient state permeability test of the closely knit standard core of quality, its method is with thermal contractible plastic cover and plastic colloidal cloth core and porous plate, last push-down head to be bundled together, and carry out radial seal by confined pressure, carry out axial seal with O type rubber seal between last push-down head and the pilot system.
Three, technology contents
(1) goal of the invention: the purpose of this utility model provides a kind of and MTS815 and the supporting attachment device that is used for fractured rock and non-fixed porosint permeability test of 816 serial rock mechanics testing systems, can finish the transient state and the steady-state permeation test of fractured rock and non-fixed porosint, expand the test function of this rock mechanics testing system, for mining with prose style free from parallelism rock permeability characteristic is studied by Geotechnical Engineering department and dynamic behavior provides technical service, also the rule research of carrying out the phenomenon of osmosis of prose style free from parallelism rock for research institution provides technological means.
(2) technical scheme: the utility model is a kind of brand-new and MTS815 and matching used fractured rock of 816 serial rock mechanics testing systems and non-fixed porosint permeability test attachment device, its major technique is characterised in that: this rock mechanics testing system attachment device comprises piston, cylinder barrel, porous plate, filter pad and web joint, is installed in the axial charger of MTS815 and 816 serial rock mechanics testing systems.Web joint is placed on the axial loaded seat of rock mechanics testing system, its center pit docks with the central passage on the axial loaded seat, cylinder barrel is by being bolted on the web joint, piston forms cavity in cylinder barrel, place test material in the cavity, upper and lower at test material all has porous plate and filter pad, and the center pit of piston docks with the central passage that axially loads spherical indenter.For realizing highly reliable sealing, piston and axially load between the spherical indenter, web joint with axially between the loaded seat, axial seal and the radial seal between cylinder barrel and the piston between cylinder barrel and the web joint all adopt O type rubber seal to seal.Extract from cylinder barrel for ease of piston, the center pit of piston and web joint is made into the screw thread of M16.
(3) technique effect: the utility model has the following advantages through actual use the in MTS815.02 type rock mechanics testing system: 1. this device sealing realizes having high reliability and (just can reach desirable sealing effectiveness under the axial load of 2kN easily; 2. when carrying out the steady-state permeation test, going out the flow liquid body can discharge, and the pore pressure system of protection rock mechanics testing system avoids polluting; 3. porous plate weakens the end effect of inflow of seepage flow liquid and outflow test material, has saved the time that confined pressure liquid charges and discharge, the test efficiency height; 4. can doublely do the compactingproperties test and the creep test of fractured rock and non-fixed porosint, and the mechanical property test after the immersion.
Four, description of drawings
Accompanying drawing is a structural profile synoptic diagram of the present utility model.
Five, embodiment
The embodiment that provides below in conjunction with accompanying drawing does the utility model and describes in further detail, as shown in drawings, the utility model is a kind of brand-new and MTS815 and supporting fractured rock and non-fixed porosint permeability test attachment device of 816 serial rock mechanics testing systems, this attachment device is installed on the axial loaded seat of rock mechanics testing system by web joint 5, in cylinder barrel 2, place filter pad 3 and porous plate 4 earlier, put into test material again, put into porous plate 4 and filter pad 3 again, piston 1 is installed at last, piston 1 docks with the axial loading spherical indenter of rock mechanics testing system, and cylinder barrel 2 is connected with web joint 5 by bolt.Be the sealing effectiveness of assurance device, between piston 1 and the spherical indenter, web joint 5 and axially between the loaded seat, axial seal between cylinder barrel 2 and the web joint 5, and the radial seal between cylinder barrel 2 and the piston 4 is passed through O type rubber seal respectively and is sealed.When carrying out the material permeability test, seepage flow liquid is from the axial loaded seat of MTS815 and 816 serial rock mechanics testing systems, enter the test material zone by web joint 5, filter pad 3 and porous plate 4, discharge through the center pit of porous plate 4, filter pad 3 and piston 1 again.
Claims (2)
1. one kind and MTS 815 and the supporting use of 816 serial rock mechanics testing systems, be used for fractured rock and non-fixed porosint permeability test attachment device, it is characterized in that: this rock mechanics testing system attachment device comprises piston (1), cylinder barrel (2), porous plate (4), filter pad (3) and web joint (5), web joint (5) is placed on the axial loaded seat of rock mechanics testing system, its center pit docks with the central passage on the axial loaded seat, cylinder barrel (2) is by being bolted on the web joint (5), piston (1) forms cavity in cylinder barrel (2), place test material in the cavity, on test material, all there are porous plate (4) and filter pad (3) in the below, and the center pit of piston (1) docks with the central passage that axially loads spherical indenter.For realizing highly reliable sealing, piston (1) and axially load between the spherical indenter, web joint (5) with axially between the loaded seat, axial seal between cylinder barrel (2) and the web joint (5), and the radial seal between cylinder barrel (2) and the piston (1) all adopts O type rubber seal to seal.
