The advantages such as speed and manufacturing cost are low, are highly widely popularized and use.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of sxemiquantitative unconfined compressive strength tester of the present invention；
In the figure, it is marked as 1- solidifies soil body sample, 2-bearing tables, 3-ballast repeated codes, 4-pilot holes, 5-guide posts, 6-are led
To block, 7-test tables, 8-adjust bolt, 9- horizontal bead.
Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples.
As shown in Figure 1, sxemiquantitative unconfined compressive strength tester of the invention, including for placing solidification soil body sample
1 rectangular bearing table 2 and for being gradually loaded into the rectangular ballast repeated code 3 for solidifying 1 upper surface of soil body sample；The ballast weight
3 two sides of code are symmetrically arranged with a square shaped guide pad 6, extend through on a pair of of guide pad 6 and are provided with a round guiding
Hole 4, ballast repeated code 3 is set to by 4 sliding sleeve of pilot hole on guide pad 6 is symmetrically arranged in two of 2 two sides of bearing table
Between cylindrical guide post 5, it is clear that the pilot hole 4 can also directly be opened in 3 two sides of ballast repeated code, then by ballast weight
Code 3 is set between guide post 5；The central position of the bearing table 2 is equipped with a rectangular test table 7, the test
The central position of workbench 7 is equipped with a shape and (does not show in figure with the locating groove that 1 shape of soil body sample matches is solidified
Out), solidify soil body sample 1 to be placed in the locating groove, the shape for the solidification soil body sample 1 that the present invention is tested is cylinder
Shape, therefore the shape of the locating groove to match with its shape is circle.
It is as above-mentioned technical proposal it is a kind of preferably, the bottom surface four corners of the bearing table 2 be respectively equipped with one with hold
The adjusting bolt 8 that object platform 2 is threadedly coupled also is inlaid with a horizontal bead 9 on bearing table 2, passes through and adjusts four adjustings
Bolt 8 simultaneously cooperates horizontal bead 9 to realize the leveling operations to bearing table 2.
The test process of sxemiquantitative unconfined compressive strength tester of the present invention is as follows:
Before test, four adjusting bolts of bearing table bottom surface are set by adjusting, are made in the horizontal bead being embedded on bearing table
Bubble it is in an intermediate position, to realize leveling operations to bearing table test table.
When specific test solidification soil body sample, the positioning that will solidify soil body sample first and be placed on bearing table test table
In card slot, the positioning to soil body sample is solidified is completed, is then calculated the compression area of soil body sample is solidified according to cylinder
The ballast repeated code that particular pressure numerical value is provided in customization is sheathed in guide post by the pilot hole on guide pad, and makes ballast weight
Successively load overlays on the top surface for solidifying the soil body circular sample cylinder code one by one, in loading procedure, avoids each ballast
It contacts on the inside of the pilot hole of repeated code with guide post, is influenced to avoid error is generated on test result, every load one has specific
When the ballast repeated code of pressure value (such as 5-10KPa), whether observation is deformed by inspection solidification soil body test specimen sample, to be loaded
Ballast repeated code is accumulated to certain amount, when observing that institute's test block sample begins with deformation tendency or cracking trend, at once
The quantity of all ballast repeated codes at this time is recorded, and is converted into the unconfined compressive strength of tested test specimen sample, i.e., ballast at this time
Repeated code quantity and the product of pressure possessed by every piece of ballast repeated code are the tested non-confining strength for solidifying soil body test specimen sample
Lower limit is spent, continues to load ballast repeated code later, until the compression of institute's test block sample is destroyed, and records all ballasts at this time
The quantity of repeated code, and be converted into the unconfined compressive strength of tested test specimen sample, i.e. ballast weight number of codes and every piece of ballast repeated code
The product of possessed pressure is the tested unconfined compressive strength upper limit for solidifying soil body test specimen sample, to test out tested solid
Change the unconfined compressive strength section of soil body test specimen sample.
The present invention (can by being gradually loaded with specified weight in the solidification soil body sample top surface with specific compression area
Be converted into corresponding pressure value) ballast repeated code, observational record solidifies soil body sample and deformation taking place and is completely being destroyed
When the ballast weight number of codes that is loaded, and be converted into the corresponding moment and solidify the unconfined compressive strength of soil body sample, to measure
Solidify the unconfined compressive strength section of soil body sample, i.e. this sxemiquantitative unconfined compressive strength tester is solidified by observation
The collapse state of soil body sample carries out test job, and in sludge curing-stabilisation work progress, general engine request
It is all to require the unconfined compressive strength for solidifying the soil body after treatment more than some numerical value, rather than require solidified earth
Body accurately reaches some special value after treatment, therefore can be applied to this sxemiquantitative unconfined compressive strength tester
In actual sludge curing-stabilisation construction work, solidify the unconfined compressive strength of soil body sample with fast and convenient measuring
Section, so that whether the unconfined compressive strength for solidifying the soil body of judgement after treatment meets practice of construction requirement, therefore this
Sxemiquantitative unconfined compressive strength tester can be widely applied for solidifying the soil body uses engineering site or laboratory quick half
Quantitative detection；Also, due to present conventional unconfined compressive strength instrument be by measure one's own ability ring or hydraulic device it is reversed come between
The compression strength parameter of tested sample is answered, and the present invention is then that resisting for tested sample is directly reacted using gravity ballast mode
In contrast Compressive Strength parameter has higher more intuitive measuring accuracy；In addition, this sxemiquantitative unconfined compressive strength is tested
Instrument also have the advantages that structure is simple, succinct, durable, measurement easy to use quickly and manufacturing cost is low etc., highly extensively
It promotes and uses.
It should be understood that above-mentioned specific embodiment of the invention is used only for exemplary illustration or explains of the invention
Principle, but not to limit the present invention.Therefore, that is done without departing from the spirit and scope of the present invention is any
Modification, equivalent replacement etc., should all be included in the protection scope of the present invention.
