Description
Technical field
The present invention relates to explosion test equipment processing and manufacturing field, be specifically related to a kind of blasting vibration installation of sensors fixture.
Background technology
In Geotechnical Engineering, explosion is a kind of common cheap quick digging mode, but rock mass carries out Blasting Excavation simultaneously, can produce a large amount of ill-effects, and wherein attenuation of seismic waves is one of them.The seismic event that explosion produces can produce adverse influence to the stability of buildings or structures around quick-fried source, in order to solve this phenomenon, at engineering site, conventionally adopt method for testing vibration to monitor its blasting vibration effect, to determine the coverage of attenuation of seismic waves and to change blasting parameter.Engineering circles method when carrying out concussion of blasting test is as follows at present: needing testing location to select the measuring point of some, normally at selecteed measuring point place, its surperficial earthing and rubble are cleared up, then by bonding agents such as the fast dry powder of gypsum, sensor is carried out bondingly, finally by data acquisition instrument, monitor.This convenient test is quick, and practical, is widely adopted.
But this blasting vibration installation of sensors technology extensively adopting at present exists following weak point: (1) is due to adhesives insufficient strength, different measuring points is successively bonding, bonding strength is variant each other, in native medium, particularly sandy soil medium bonding material and medium are understood bonding not going up, easily having there is pitching in various degree in sensor, can not obtain valid data; (2) use which kind of bonding agent all can produce sensor stained, cleaning up bothers very much; (3) bonding agent needs certain set time, increases tester's workload.
Summary of the invention
The vibration transducer major part that blasting vibration test is at present used is: long 6.4cm, wide 6.4cm, high 6.4cm, the square magnetoelectric velocity transducer of weight 644g, therefore the object of the invention is mainly in native medium, to carry out when concussion of blasting is tested how installing efficiently and stably in the wild for sensors with auxiliary electrode were, has designed a kind of blasting vibration installation of sensors fixture that is applicable to native medium.
In order to solve existing problem in background technology, it comprises train wheel bridge 1 and lower plate 2, described train wheel bridge 1 and the two ends on lower plate 2 offer respectively corresponding upper screw hole 3 and lower screw hole 4, described train wheel bridge 1 and lower plate 2 are provided with screw rod 5, the upper end of this screw rod 5 is through upper screw hole 3, its lower end is through corresponding lower screw hole 4, and the two ends of described screw rod 5 are connected with hold-down nut 6, and the both sides of described lower plate 2 are provided with fixed orifice 7.
Between described fixed orifice 7, being isosceles triangle shape arranges.
The hold-down nut 6 that described screw rod 5 is positioned at screw hole 3 one end is big-ear formula nut.
Owing to having adopted above technical scheme, the present invention has following beneficial effect: simple in structure, easy for installation, sensor is not easy to pitch in the process of explosion, can obtain active data, has good adaptability; Can not produce sensor stained, easy to clean; Installation rate is very fast, has reduced tester's workload.

Embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
Referring to Fig. 1-3, this embodiment is to be achieved by the following technical solutions, it comprises train wheel bridge 1 and lower plate 2, described train wheel bridge 1 and the two ends on lower plate 2 offer respectively corresponding upper screw hole 3 and lower screw hole 4, described train wheel bridge 1 and lower plate 2 are provided with screw rod 5, and the upper end of this screw rod 5 is through upper screw hole 3, and its lower end is through corresponding lower screw hole 4, the two ends of described screw rod 5 are connected with hold-down nut 6, and the both sides of described lower plate 2 are provided with fixed orifice 7.
Described determine to be isosceles triangle shape between hole 7 and arrange together.
The hold-down nut 6 that described screw rod 5 is positioned at screw hole 3 one end is big-ear formula nut.
Embodiment 1
The first step: select point position, and top layer earthing is removed, a large amount of earthing can have a strong impact on the stability of whole installation of sensors;
Second step: determine installation direction, according to actual test request, determine the relative direction in sensor and quick-fried source, conventionally the directions X of lower plate 2 is pointed to quick-fried source side to;
The 3rd step: steel nail, through fixed orifice 7, is knocked in the soil body with hammer, fixed lower plate 2;
The 4th step: the placement of aliging of piece directions X is stepped up in the directions X of blasting vibration sensor a and bottom, and by screw rod 5 with determining nut 6, blasting vibration sensor a is clamped between train wheel bridge 1 and lower plate 2;
