Description
Technical field
The present invention relates to pressure testing protective devices, and in particular to a kind of anti-rubble being arranged on pressure testing machine splashes
Collection device.
Background technology
With the rapid development of concrete technology, high-strength concrete is as a kind of new construction material, in particular to resistance to compression
Intensity meets or exceeds the concrete of 60MPa, superior with its compression strength is high, non-deformability is strong, density is big, porosity is low
Property, it is widely applied in fields such as science of bridge building, skyscraper, ocean engineering and mine constructions.
The characteristics of high-strength concrete is maximum is compression strength height, generally the 4~6 of regular tenacity concrete times, with coal mine
For borehole wall concrete, as New Built Mine passes through table soil alluvium and rock section more and more deeper, it is desirable that the borehole wall can sustain
The complicated external load effect such as powerful ground pressure, hydraulic pressure, therefore the borehole wall strength grade of concrete made at this stage is higher and higher,
Highest has case of the C100 concrete applications of result in engineering practice.
But concrete is as a kind of fragile material, with strength grade, to improve Brittleness all the more apparent.Usually in reality
When testing progress high-strength concrete uniaxial compressive strength test on indoor pressure testing machine, test specimen destruction shows sudden, anxious
The characteristics of rush property, be embodied in and send out suddenly " bang " loud noise, destroy immediately, and destroy preceding without any apparent sex character
Million.Since concrete sample is flash disruption, the most of energy moment saved bit by bit in loading procedure is released so that comes off
Rubble splashes, and rubble has corner angle mostly, if certain journey can inevitably be caused by being splashed to human body face or skin exposed section
The injury of degree, therefore be very unsafe for testing crew.Secondly, just because of Brittleness of Concrete feature it is apparent, destroy
The characteristics of rapid, testing crew be in security consideration can not close-ups to the entire full mistake of high-strength concrete uniaxial compressive test
The situation of change of crackle during the Initiation And Propagation perforation situation, especially critical slope langth of journey crackle, therefore high-strength concrete single shaft is resisted
Press each stage stress of overall process and the grasp of the correspondence of crack growth situation not thorough.
Accordingly, it is desirable to provide a kind of improved technology scheme insufficient for the above-mentioned prior art.
Invention content
