Description
Technical field
The present invention relates to a kind of method with ultrasound examination multilayered medium coupling mass, belong to Ultrasonic Detection and analysis technical field.
Background technology
At engineering construction field, because underground structure stands Water And Earth Pressures and the reason such as structure self is aging for a long time, make the local sedimentation of structures, cracking, distortion, therefore need these structures to carry out local stiffening, as the strengthening reconstruction of tunnel-liner etc.Reinforce the general steel plate materials (according to requirement of engineering) that adopts thickness not wait, the ectonexine of steel plate adopts multiple compound substance to carry out anticorrosion, anti-aging processing, according to engine request, adopt Standard Module to make steel plate structures reinforcing member, these reinforcing members are " standard components " of unified size.But actual conditions are, underground structure is due to discontinuity, build the reasons such as asynchronism(-nization), distortion, bending, cracks etc. are damaged different, therefore, reinforce the structures of Local Damaged with " standard component ", between structures and reinforcing member, can there is the space differing in size, general gap thickness reaches several centimeters, extreme gap thickness is up to tens of centimetres, whole space filled by reinforcement material by the special device of general employing, guarantee the coupling mass of reinforcing member, make new after reinforcing, old structures become stressed uniform entirety, otherwise, if still there is space in part, stressed meeting inhomogeneous (having the position in space not stress), new non-uniform settling will be produced, distortion.Therefore, be full of after reinforcement material, need to detecting it, determining its coupling mass.
Existing building trade detection method has electromagnetic radar method, ultrasonic Detection Method, X ray and gamma-rays method etc.Because the relative dielectric constant of steel plate is very high, in the time that electromagnetic wave passes steel plate, almost entirely absorbed by steel plate, therefore electromagnetic radar method cannot be used for this detection.
The steel construction of ultrasonic Detection Method in building trade detects the flaw detection that is mainly used in welding joint, weld seam.Ultrasonic Detection Method concrete density in building trade detects, and is that when measurement, according to sound, duration judges the concrete defect degree between transmitting transducer and receiving transducer at concrete positive transmitting transducer, the reverse side installation receiving transducer installed.
X ray and gamma-rays method are known from experience and are damaged and cost costliness people, are not generally suitable for building trade and detect.
Therefore there are the following problems, to utilize existing technology for detection multilayered medium coupling mass:
One, electromagnetic radar method is because the absorption effect of steel plate cannot be used for this detection; Two, ultrasonic Detection Method need to detect at the positive and negative of material installation transducer, but the reinforcing of underground structure (as tunnel) detects, and because reverse side is at Rock And Soil, transducer cannot be installed, so can only carry out in front, invalid to underground structure reinforcing detection; Three, to be only applicable to surface for Welded Joint in Steel, seam inspection be that steel structure material and investigative range are shallow to ultrasound wave, and underground structure reinforcing body surface is for anti-corrosion material and have multilayered medium, therefore inapplicable; Four, X ray and gamma-rays method, because of high to human injury and cost, are not suitable for the detection on a large scale in underground structure reinforcing.
