Abstract
The utility model belongs to a rock mass CT detector which detects rock masses and tests engineering quality and engineering foundation in a geotechnical engineering and a mineral engineering. The utility model is mainly composed of a transmitter and a receiver connected with the transmitter through a microcomputer controlling and processing instrument. The utility model is characterized in that the transmitter is connected with a transmitting probe through a cable wire, and the receiver is connected with a receiving probe through the cable wire. The utility model realizes the spatial two-dimensional or three-dimensional detection of the rock masses, and a detecting result has high precision and high resolution, so the utility model is a novel detector.
Description
The utility model belongs to the instrument that in Geotechnical Engineering and the Mineral Engineering rock mass detection, construction quality detection, engineering foundation is detected, and is a kind of novel rock mass CT detection instrument.
At present rock (soil) body is implemented to survey, the main instrument and equipments such as rig, sonic apparatus, density instrument, stress one strain gauge that adopt, these instrument and equipment measured results all are the rock mass structure states in tested borehole wall of reflection and the nearly wall scope, just " a peephole view ", can not reflect the peripheral rock mass structure state of hole wall, and the measurement result degree of accuracy is on the low side, thereby measured result often loses directive significance to engineering, even wrong conclusion occurs.
The purpose of this utility model is to rock mass implementation space two dimension or three-dimensional detection, result of detection can not only reflect the rock mass structure state in the borehole wall scope, and can reflect the peripheral rock mass structure state of hole wall, and reach the high-efficiency high-accuracy high-resolution and survey, be a kind of novel rock mass CT detection instrument.
The receiver that the utility model mainly links to each other with transmitter by transmitter, by system controlled by computer and processing instrument is formed, and it is characterized in that transmitter is connected with transmitting probe by cable, and receiver is connected with receiving transducer by cable.
The utility model adopts many probes to transmit and receive the data acquisition efficiency height.Utilize two or more borings and the rock mass cross section of combination in any, but implementation space two-dimensional measurement or three-dimensional measurement.Owing to can control measuring point spacing or the rare close degree of ray by the spacing of regulating probe, so suitably encrypt measuring point, guarantee enough radiographic densities, can guarantee the detection of high precision and high resolving power.
Description of drawings: Fig. 1 is a structured flowchart of the present utility model, and 1 is transmitter among the figure, and 2 is receiver, the 3rd, and system controlled by computer and processing instrument, the 4th, cable, the 5th, transmitting probe, the 6th, receiving transducer, the 7th, telescoping ram.
The receiver that the utility model mainly links to each other with transmitter by transmitter, by system controlled by computer and processing instrument is formed, and transmitter is connected with transmitting probe by cable, and receiver is connected with receiving transducer by cable.Transmitting probe, receiving transducer are put into boring A, the B that has bored respectively, the computer control transmitter produces pulse signal and arrives transmitting probe through cable transmission, producing ultrasound wave in boring A propagates in rock mass, the ultrasonic propagation direction is omnibearing, but wherein must there be a ray to pass to the receiving transducer of boring among the B, the acoustical signal that receiving transducer receives is delivered to receiver through cable, receiver is gathered, is stored signal in computer control with under handling, machine carries out CT imaging calculating, explains as calculated at last, generates achievement sectional view (or planimetric map).For the coupling that guarantees to pop one's head in the wall of a borehole, can in boring, inject water, but in boring under the anhydrous situation, can utilize telescoping ram backup probe, the effect of telescoping ram mainly plays mechanical backup effect, by the elasticity jam-packed probe and the borehole wall of spring steel plate, guarantee that probe and borehole wall rock mass are coupled.If expose the detection of rock mass, can measure directly transmitting and receiving the periphery that probe is placed in tested rock mass.C is the measured target rock mass, when it is static state, can survey once, when it is dynamic change, can the branch different time sections survey.
Transmitting probe is designed to 6 or some more, and receiving transducer can be 6 or more, and it is many more to transmit and receive probe, and efficiency of measurement is high more, and the spacing between transmitting probe and the receiving transducer has determined measuring accuracy and resolution.When high-accuracy high-resolution was measured, transmitting probe and receiving transducer spacing value should be little, generally get 0.5 meter of spacing.Because this device is to measure between the hole, so realized the space two-dimensional measurement,, can carry out any two hole measurements among the porous if there is porous to exist, according to the borehole space syntagmatic, the implementation space three-dimensional measurement.
Transmitter can adopt TYF-1A type high-power transmitter in the utility model, and receiver can adopt SYC-2 type sonic receiver, and transmitting probe can adopt DPF series transmitting probe, and receiving transducer can adopt the DPF receiving transducer.
