Description
Technical field:
This utility model relates to rock mechanics detection equipment technical field, is specifically related to a kind of detecting earth stress device.
Background technology:
Stressometer is the instrument measuring crustal stress.The rigidity of the sensor used in the stress measurement of base area is different, sensor can be divided into two kinds: if the rigidity of ratio of rigidity institute geodetic point rock is big, referred to as stressometer；If less than the rigidity of tested area rock, then claim deformation gauge or strain gauge.Stress meter rigidity is big, the biggest ability is had to revolt rock deformation, and the stress that the pressure that born itself depends primarily in rock, little with the elastic constant relation of rock, the biggest this effect of rigidity is more obvious, is not required to accurately measure the elastic constant of rock with it when therefore measuring.Strain gauge is then contrary, its deformation extent except having with the stress in rock outside the Pass, also relevant with rock elasticity constant, must accurately measure the elastic modelling quantity of rock during geodetic stress.There are pressure magnetoelectric induction power meter, vibratory string stressometer, steel loop stressometer, electric capacity stressometer and photoelastic stressometer etc. multiple.
Traditional hollow inclusion detecting earth stress device needs punching, cleans and the filling of adhesive, operates cumbersome.
Utility model content:
The purpose of this utility model is the defect for prior art and deficiency, it is provided that a kind of detecting earth stress device, and its simple in construction is novel in design, it is possible to realize Rapid Cleaning and the rock ballast suction of test hole；Fast Filling adhesive can also be carried out simultaneously, convenient and practical.
In order to solve the problem existing for background technology, a kind of detecting earth stress device of the present utility model, it comprises hollow inclusion, strain rosette, upper connection terminal, signal cable, lower connection terminal, multi-functional filler pipe, hole cleaning head, apopore；The surface configuration of described hollow inclusion has strain rosette, the two ends of hollow inclusion are connected to connection terminal and lower connection terminal, the left side of upper connection terminal connects signal cable, signal cable is connected with strain rosette, described hollow inclusion be internally provided with multi-functional filler pipe, multi-functional filler pipe each extends over supreme connection terminal and the outside of lower connection terminal, and the right-hand member of described multi-functional filler pipe connects hole cleaning head, and the surface configuration of hole cleaning head has several apopore.
As preferably, described strain rosette is made up of annulus welded plate and resistance strain, in 72 degree of angles between the resistance strain that resistance strain transverse weld is on annulus welded plate and adjacent.
As preferably, described hollow inclusion with on be connected between terminal, lower connection terminal for seamless link.
Compared with prior art, the beneficial effects of the utility model are: it is novel in design, and the one section of conveying that is internally provided with at hollow inclusion is managed, it is possible to Rapid Cleaning and the rock ballast of test hole are aspirated by matching purge head；Simultaneously can also be convenient and practical by filling adhesive fixation hollow inclusion in conveying pipe first cavity.
