In the engineering test field; In order to study that the hole crack of construction material such as rock under stress field and seepage field coupling situation distributes and characteristic such as expansion; Need triaxial test that parameters such as the sonic transmissions speed of construction materials such as rock and water permeability are tested; At the trial; Be required to be three servo test system configuration, one cover pressure-bearing infiltration type sounding probe, promptly in order to satisfy testing requirements, except the need such as strength and stiffness of popping one's head in are complementary with construction materials such as three servo test mechanisms and rocks; Probe need possess outside the sonic sensor of functions such as having sound wave emissions and reception, and probe also will possess the function of the construction materials of being tested such as rock being carried out infiltration pore water.
In order to make test findings meet the objective characteristic of construction materials self such as rock more; To draw objective and accurate infiltration result, need ask corresponding coupling of the infiltration lane in probe and the construction material sample such as rock should meet the distribution characteristics in the hole crack of construction materials such as rock as far as possible.
Because of the inside of construction materials such as rock and the hole crack that is formed at the surface are random distribution; And present existing pressure-bearing infiltration type sounding probe its be used to carry the pore water through hole of infiltration water to be arranged on the center of the pressure-bearing surface of probe more; Not corresponding with the hole crack of construction material stochastic distribution such as rock; Water can not evenly be permeated in the hole crack effectively; Cause to draw objective and accurate permeability test result, and then influence the overall reliability of whole threeaxis test results, distribute and extended attribute to such an extent as to can not study the hole crack of construction material such as rock under stress field and seepage field coupling situation scientifically and rationally.
The utility model content
The purpose of the utility model is to provide a kind of engineering to pop one's head in the sounding of pressure-bearing infiltration type; It can make water evenly permeate effectively in the hole crack of construction materials such as rock, and then can study the hole crack of construction material such as rock under stress field and seepage field coupling situation scientifically and rationally and distribute and extended attribute.
In order to achieve the above object, the utility model adopts such technical scheme:
A kind of engineering comprises the probe body with pressure-bearing infiltration type sounding probe, and said probe body has the pore water through hole, and the pressure-bearing surface rule of said probe body is laid with groove, said groove and said pore water through hole UNICOM.
Above-mentioned probe body is cylindric, and above-mentioned groove is annular concentric and radially is crisscross arranged.
Above-mentioned pore water through hole is laid in the intersection point place of above-mentioned groove.
The pressure-bearing surface of above-mentioned probe body is with permeable pad.
Above-mentioned probe body has the sound wave transducing head.
