Description
Technical field
The present invention relates to blasting vibration measurement equipment to fabricate field, and in particular to one kind is suitable for hard rock long term monitoring
Blasting vibration mounting frame for sensor, blasting vibration measurement system and blasting vibration measurement method.
Background technology
Explosion is widely used to mine, water conservancy and hydropower, highway, tunnel etc. as a kind of economical and effective digging mode
In work progress, however the ill effects such as noise, dust, pernicious gas, blasting vibration can be generated simultaneously in blasting process, wherein
Blasting vibration has larger danger, a certain range of personnel, equipment, house, important building etc. can be caused seriously
Damage, country correlation regulation also to explosion generate Blasting Vibration Velocity have clearly stipulate that therefore being carried out in blasting process
Blasting vibration measurement has great importance.Blasting vibration measurement equipment is generally by sensor, vasculum and connecting line group at present
Into sensor being fixed on pretest position before explosion, connection equipment, arrange parameter, in blasting process acquiring explosion shakes
Dynamic relevant information.
In test process, the installation of sensor plays the accuracy of test result vital.Usually first will
Surface layer scum silica frost, rubble etc. are cleared up, and are then fixed sensor and the rock after cleaning using gypsum, and such as patent, (one kind is suitable
Blasting vibration sensor installs fixture, a kind of fixing means of blasting vibration measurement vibration pickup for soil-structure interactions) it uses peace
Sensor is fixed in soil-structure interactions or weathered layer and carries out blasting vibration measurement by clamps, but it uses steel nail directly will installation
Fixture is fixed on soil-structure interactions or regolith surface, and the method does not apply to hard rock, while this method is disposable installation, is installed
The leveling of sensor and the quick-fried heart of alignment can not be adjusted afterwards, and rock hard rock blasting vibration monitoring still mainly fixes sensing using gypsum at present
The method of device.
There is following shortcomings for this blasting vibration sensor mounting technique widely used at present：
(1) the thickness difference of gypsum has result apparent influence；
(2) when being installed using gypsum, adhesion strength is more by ratio, the consolidation time of land plaster quality, land plaster and water etc.
Factor influences, it is difficult to ensure that the test condition of measuring point is consistent；
(3) it is fixed using gypsum, surface relaxation need to be cleared up and destroy rock stratum, it is cumbersome；
(4) fixed form used at present is cleaned out so that test knot for hard rock it is difficult to which surface layer is relaxed and destroys layer
Fruit is less than normal, it is understood that there may be security risk；
(5) when such as hydraulic tunnel, mine are needed to repeatedly being tested in region, to protect equipment, most of at present is every
It is secondary to be both needed to be installed, dismantle, it takes time and effort；
As it can be seen that develop it is a kind of for hard rock, it can be achieved that the easy blasting vibration sensor installation being used repeatedly
Stent has apparent realistic meaning and engineering demand.

Direction；
Step 3 is fixedly mounted platform and the X-direction of mounting platform is aligned the quick-fried heart；
Step 4, fixed blasting vibration sensor；
Step 5 carries out blasting vibration measurement to acquire blasting vibration data.
Compared with prior art, beneficial effects of the present invention：
(1) present invention improves the accuracy of test result：Inside the deep enough rock mass of mounting bracket energy, across rock mass pine
Relaxation layer, and rock mass surface test is mainly fixed on, test result is closer to very using land plaster using metal conduction than before
Real value；
(2) present invention improves long term monitoring efficiency：Test is required to install, and when gypsum sets need conventional method every time
Between, the method for the invention used is installed for the first time needs certain time, and later stage monitoring only needs to install sensor in test,
Used time is short, and without waiting for the time；
(3) present invention improves data validity：Sensor is not easy to loosen after fixing, and repeatedly test mounting condition is more consistent,
The data validity measured is improved, is conducive to multiple comparative analysis；
(4) present invention improves single-spot testing range：Its X-direction of sensor installation requirement is directed toward the quick-fried heart, conventional method 1
Measuring point is only used for explosion at test 1, this stent mounting platform direction is adjusted, when measuring point nearby has many places explosion, it is only necessary to adjust
Mounting platform direction is saved, improves single-spot testing range.
