Abstract
The invention is a saturation reinforced clay triaxial test sample preparation mould. The mould comprises a sample preparation circular cylinder that the inner wall is smooth and the upper and the lower parts are open; the sample preparation circular cylinder is arranged on a base seat; on the wall of the sample preparation circular cylinder, inner screwed holes are symmetrically arranged at reinforced height position according to a preset sample, so that screws are matched rotatably; a reinforced slice is horizontally put at the inner end of the screws stretching into the cylinder wall; the upper part of the inner cavity of the sample preparation circular cylinder is matched with a bearing plate, and drain holes are distributed on the bearing plate; the base seat is formed in a way that a drip mold is collocated below a porous plate; and drip holes are evenly distributed on the porous plate. In the invention, the compactness of each part of the sample is even, thus ensuring the horizontal position of added reinforced slices in soil sample; the preparation of triaxial test clay sample is simple and convenient, thus saving the sample preparation time and improving the quality of the sample preparation.
Description
Technical field
The present invention relates to the saturated reinforcement soil triaxial test sample preparation mold in a kind of civil engineering work soil test field.
Background technology
Triaxial test is widely used in studying the reinforced earth Reinforced Mechanism always.Triaxial test can reflect the sample stress deformation until the process of destroying, and both can do the intensity test, also can do the stress-strain relation test.The notion of reinforced earth itself proposes according to threeaxis test results.Therefore triaxial test is the indispensable test method of research reinforced earth.
Novel reinforced earth triaxial test specimen preparation utensil of the present invention adopts saturated clay to adopt the load time effect that sample is carried out discharging consolidation, and default bolt is fixed reinforcement material in mould, is arranged in predeterminated position to guarantee reinforcement material.Preparation method of sample is easy, and the sample preparation time is short, and the reinforcement stationkeeping is difficult for deviation takes place, guarantee that specimen preparation is finished after, reinforcement material can level be laid in the predeterminated position in the soil sample.
Summary of the invention
The object of the present invention is to provide a kind of saturated reinforcement clay triaxial test sample preparation mold, guarantee muscle sheet maintenance level in position in preparation process of reinforcement clay sample inside, deviation does not take place, simple and efficient preparation reinforcement soil sample.
The object of the present invention is achieved like this:
A kind of saturated reinforcement clay triaxial test sample preparation mold comprises that the sample preparation cylinder of the inwall brilliance of a upper and lower opening is placed on the base, it is characterized in that:
1). on the barrel of described sample preparation cylinder, be provided with the internal thread hole of symmetry by predetermined sample reinforcement height place, rotary screw in described internal thread, the level on the inner of barrel of stretching at described screw is shelved the muscle sheet of sample reinforcement;
2). bearing plate of described sample preparation cylinder bore top configuration, uniform osculum on the described bearing plate; Water filter plate of sample preparation cylinder bore bottom configuration;
3). described base disposes a drip and constitutes below a porous disc, described porous disc upper surface has circular groove and described sample preparation cylinder coupling, uniform weeper on the porous disc.
On the barrel of above-mentioned sample preparation cylinder, have the multilayer height to be provided with the internal thread hole of symmetry, in the internal thread by predetermined sample reinforcement height place, the screw of screw-in stretches in the barrel; In the internal thread hole of reinforcement, the screw of screw-in is inner not to flush with the barrel inwall for all the other.
The present invention has following advantage compared with prior art: 1 reserves the hole of band internal whorl on the sample preparation mould, the available screw muscle sheet that fixedly rigidity is bigger, and deflection takes place in muscle sheet position when avoiding sample preparation.2, at sample preparation mould bottom design drip, avoid muddy water that instrument is caused corrosion.
Description of drawings
Fig. 1 is a sample preparation mould structure synoptic diagram of the present invention.
Embodiment
Details are as follows in conjunction with the accompanying drawings for a preferred embodiment of the invention: referring to Fig. 1, this saturated reinforcement clay triaxial test sample preparation mold, the sample preparation cylinder that comprises the inwall brilliance of a upper and lower opening is placed on the base, on the barrel of described sample preparation cylinder, be provided with the internal thread hole of symmetry by predetermined sample reinforcement height place, rotary screw in described internal thread, the level on the inner of barrel of stretching at described screw is shelved the muscle sheet of sample reinforcement; Bearing plate of described sample preparation cylinder bore top configuration, uniform osculum on the described bearing plate; Water filter plate of sample preparation cylinder bore bottom configuration; Described base disposes a drip and constitutes below a porous disc, described porous disc upper surface has circular groove and described sample preparation cylinder coupling, uniform weeper on the porous disc.
On the barrel of above-mentioned sample preparation cylinder, have the multilayer height to be provided with the internal thread hole of symmetry, in the internal thread by predetermined sample reinforcement height place, the screw of screw-in stretches in the barrel; In the internal thread hole of reinforcement, the screw of screw-in is inner not to flush with the barrel inwall for all the other.
During the preparation sample, on sample preparation cylinder 6 inwalls, evenly smear lubricant earlier.After drip 1, water filter plate 9 and sample preparation cylinder 6 are put well successively the fractional saturation clay is inserted in the tube.The screw 3 at design reinforcement position is screwed into preformed hole, and muscle sheet 4 is placed on the screw 3, continue to put into saturated clay.Saturated clay by testing requirements add finish after, in sample preparation cylinder 6, put into bearing plate 7, the boosting-rod on the sampling instrument lever with after bearing plate 7 fully contacts, is pressurizeed with counterweight by design load, and static certain hour.After loading certain hour, the saturated soil body has certain intensity, and fixedly the screw 3 of muscle sheet 4 screws out again, but still can block the aperture.Because the existing certain intensity of soil body this moment, muscle sheet 4 with can not be offset by occurrence positions after the soil body contacts, the aperture also still has screw 3 to block, and can not spill muddy water.Specimen preparation by design load continuation loading finishes then.
