Description

A kind of Quick plane plate load test instrument
Technical field
The present invention relates to a kind of checkout equipment, particularly relate to a kind of Quick plane plate load test instrument.
Background technology
Plate is the common method for detecting Subgrade Compaction Quality, mainly comprise ground coefficient K30 test and secondary deformation modulus Ev2 test.Traditional plate method is by different-diameter loading plate repeated loading or unloading, judges soil compaction quality according to its load and deflection relation.Traditional detection instrument in use shows certain weak point, on the one hand because roadbed considers that when designing draining needs, the weathering of certain slope can be made to both sides by line midline, as 2%, 4%, in order to the level of loading plate during warranty test, usual before the test test surfaces to be dug to level, or adopt dry sand, gypsum putty etc. that test surfaces is adjusted to level; On the other hand, in process of the test, need keep the regular hour at constant pressure, as required in railway engineering, ground coefficient K30 is tested, and all keeps constant voltage to be no less than 3min under 0.04MPa, 0.08MPa, 0.12MPa equal pressure.At present in test due to cannot constant pressure be kept, therefore by artificial constantly ftercompction.Above two aspects, will cause the inaccurate of plate result, and increase human factor impact in process of the test.
Summary of the invention
The object of this invention is to provide a kind of easy and simple to handle, result accurately objective Quick plane plate load test instrument.
The object of the invention is to be achieved through the following technical solutions:
Quick plane plate load test instrument of the present invention, comprise and survey bridge, loading plate, described loading plate is provided with device for pressure measurement, described device for pressure measurement is provided with lifting jack, described survey bridge is provided with displacement measuring device, the chaining pin of institute's displacement measurement device and the surface contact of described loading plate, described device for pressure measurement and displacement measuring device are respectively by wire and data processing equipment.
As seen from the above technical solution provided by the invention, the Quick plane plate load test instrument that the embodiment of the present invention provides, bridge, loading plate is surveyed owing to comprising, loading plate is provided with device for pressure measurement, device for pressure measurement is provided with lifting jack, surveys bridge and is provided with displacement measuring device, the chaining pin of displacement measuring device and the surface contact of loading plate, device for pressure measurement and displacement measuring device, respectively by wire and data processing equipment, have easy and simple to handle, the result accurately advantage such as objective.

Institute's displacement measurement device is hundred clock gauges or displacement transducer.
Described device for pressure measurement is pressure transducer or LOAD CELLS.
Data processing equipment, can the test figure of pick-up transducers, and operates the operation valve opening and closing of lifting jack.
Specific embodiment:
As shown in Figure 1, the basic step using Quick plane plate load test instrument to carry out testing is as follows:
1. on road bed to be detected, selected test point.
2. assemble instrument, displacement tester is fixed on the support of survey bridge, and the probe of displacement tester contacts with loading plate end face.Loading plate is directly positioned on road bed, without the need to smooth in advance, and the oil cylinder of its top placement force proving installation, lifting jack successively.Data processing equipment is connected with the operation valve of displacement tester, pressure test device and lifting jack respectively.
3. carry out load or unload test, in process of the test, when arriving the spot pressure of regulatory requirements, data processing equipment makes operation valve close, and keeps pressure constant state.
4. when after arrival official hour, data processing equipment makes operation valve open, and proceeds load or unload operation, and so forth until off-test.
5. after off-test, data processing equipment can calculate test findings automatically, and by mini-printer field print, the data that also can be connected with computing machine are transmitted.
Quick plane plate load test instrument of the present invention, has that installation rate is fast, easy and simple to handle, a result accurately advantage such as objective.Before test, do not need to dig level road basal plane, avoid the test error that classic method leveling test surfaces brings, the oil pressure of automatic control jack, enables pressure keep constant, improves test accuracy simultaneously, save test period, reduce the labour intensity of testing crew.
The above; be only the present invention's preferably embodiment, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
