Description
Technical field
The invention belongs to intensity and deformation test technical field in rock-soil mechanics, be specifically related to a kind of portable rock
Soil body surface intensity nondestructive test instrument.
Background technology
The surface strength of Rock And Soil is one of important indicator evaluating Rock And Soil weatherability, in ground ruins
In recovery project, it usually needs repairing effect is evaluated by the surface strength measuring ground ruins.Evaluate rock
The best means of soil body surface repairing and reinforcement effect is that the Rock And Soil historical relic after repairing is placed under natural environment,
Long-time observe repair after the weatherability of ground historical relic body, but it practice, owing to time scale is excessive,
The weatherability of long-term observation ground historical relic body does not possess feasibility, it is impossible to scientific evaluation consolidation effect.
Accordingly, it would be desirable to reinforcement and repair effect is detected and evaluates by other means immediately.At present strong to Rock And Soil
Degree detection method belongs to destructive detection, and one of basic principle of historical relic reparation is minimum of interference, conventional
Rock And Soil strength test method protectiveness can be caused to destroy earthen ruins.In addition, ground matter historical relic
Body mostly is and is in weathered state, and its mechanical strength is low, and the thickness carrying out historical relic reparation is less, therefore, all
Such as large power test instruments such as concrete bouncing back instruments, it is impossible to ensure ground historical relic itself is not produced destruction.
The Chinese invention patent of Application No. CN200710063029.4, discloses a kind of mensuration rock wear-resisting
Property method, the method use draw point abrasion rock surface, by micrometering instrument measure the rock indenture degree of depth
Determine the wearability of rock, due to the immovability of ground matter historical relic, Application No.
The Chinese invention patent of CN200710063029.4 can not meet the demand of Site Detection.
Based on use above demand, the present invention provides a kind of portable Rock And Soil surface strength tester, passes through
The power of nondestructive measurement press-in Rock And Soil and displacement determine the surface strength of ground matter historical relic, and then evaluate ground matter
The repairing and reinforcement effect of historical relic.
Summary of the invention
In order to fill up the blank of Rock And Soil cultural artifact surface intensity non-destructive testing, the present invention provides a kind of portable rock
Soil body surface intensity lossless survey instrument, can monitor power and the numerical value of displacement of press-in soil body process in real time；Can be indirectly
Measure the surface strength of Rock And Soil, be the device evaluating a kind of effective simplicity of Rock And Soil historical relic repairing effect.
Portable Rock And Soil surface strength tester, is made up of press-in device part and surveying record part, institute
State press-in device part to be made up of handle 1, feeler lever 2, sleeve 3 and conical probe 4；Described surveying record
Part is made up of pressure transducer 5, displacement transducer 6 and signal recorder 7.
Ultimate principle and technology: under external force, the degree of depth of conical probe press-in Rock And Soil and ground body surface
Face intensity is proportional.According to pressure transducer and displacement transducer real time record signal, taper can be obtained and visit
The head press-in degree of depth of Rock And Soil and conical probe to Rock And Soil merit, so that it is determined that Rock And Soil surface is strong
Degree.
Feeler lever 2 is made of stainless steel, a length of 200mm, a diameter of 10mm, and conical probe 4 is by stainless
Steel is made, and probe total length is 80mm, and cone height is 17.32mm, a diameter of 20mm.
Under external force, it is assumed that it is d that conical probe 1 is pressed into Rock And Soil case depth, unit is mm,
Conical probe 4 is external force integration on direction of displacement to Rock And Soil work.
The data recorded according to pressure transducer 5 and displacement transducer 6 draw displacement-outer force curve, then bent
The area of the figure that line and coordinate axes surround is that external force is to Rock And Soil surface work done, it is assumed that displacement-external force
The area of the figure that curve and coordinate axes surround is S, and unit is mm2。
The degree of depth that conical probe 4 is pressed into the soil body to Rock And Soil work done with ground soil strength and feeler lever just becomes
Ratio relation, is pressed into Rock And Soil case depth d with area S divided by conical probe 1, i.e. obtains Rock And Soil surface
Intensive parameter.
Accompanying drawing explanation

Detailed description of the invention
Embodiment 1
A kind of portable Rock And Soil surface strength nondestructive test instrument, by press-in device part and surveying record part
Composition, described press-in device part is made up of handle 1, feeler lever 2, sleeve 3 and conical probe 4；Described measurement
Record part is made up of pressure transducer 5, displacement transducer 6 and signal recorder 7.
Handle 1 is connected with feeler lever 2, accesses pressure transducer 5 between handle 1 and feeler lever 2.
Displacement transducer 6 is accessed in feeler lever 2.
Pressure transducer 5 and displacement transducer 6 are accessed in signal recorder 7.
After instrument assembles, conical probe 4 is made to connect with the reinforced Rock And Soil surface repaired by handle 1
Touch.
The zeros data that pressure transducer 5 and displacement transducer 6 are recorded.
Applying external force, logical handle 1 makes conical probe 4 be pressed into Rock And Soil surface, by signal recorder 7 record pressure
Force transducer 5 and the data of displacement transducer 6.
By computer drawing displacement-outer force curve, and calculate the figure that displacement-outer force curve surrounds with coordinate axes
