Abstract
The utility model discloses a rock pervasion experiment pressure head based on servo test system, belonging to rock pervasion experiment field, including cylindrical pressure head noumenon with through hole opened in the centre of circle, the cylindrical pressure head noumenon is provided with four to sixteen rows through holes radioactive around the centre of circle, furrows interconnect to each other are disposed between through holes of every other rows on upper surface of pressure head noumenon; lower surface of the pressure head noumenon is provided with annular furrow with the through holes disposed inside. The pressure head is provided with advantage of high stiffness and experimental result conforming to practicality better.
Description
Technical field
The utility model relates to a kind of pressure head of rock permeability experiment usefulness.
Background technology
When carrying out the permeability test of rock, except requiring the servo experimental system of rock to possess enough rigidity and responsiveness, to satisfy outside the rock mechanics requirement of experiment, also necessarily require rock sample and the Contact Coupled of permeating the water stream channel in the pressure head should meet the hole crack feature of rock as far as possible, so just can make the rock permeability experimental result more meet the objective Penetration Signature of rock, draw scientific and reasonable permeability test result.Because rock surface and inner hole crack are scattered in stochastic distribution, therefore, guaranteeing under the situation that permeability test pressure head intensity and rigidity and the servo experiment frame of rock are complementary, should as far as possible greatly and be evenly distributed with the contacted water stream channel area of rock sample in the infiltration pressure head, the permeability test result could more meet the actual conditions of rock, just can draw more realistic Penetration Signature parameter.At present, there be surface and the inner unmatched defective of hole crack distribution characteristics with rock in the rock permeability of rock servo test system configuration experiment pressure head, can not draw the permeability test result who tallies with the actual situation during permeability test.
Summary of the invention
The purpose of this utility model is to provide the rock permeability experiment pressure head based on the servo test system, and this pressure head has advantages such as rigidity height, experimental result be more realistic.
The technical scheme in the invention for solving the above technical problem is: based on the rock permeability experiment pressure head of servo test system, comprise cylindrical pressure head body, the circle centre position of pressure head body offers through hole, offering with the center of circle on the described cylindrical pressure head body is radioactive 4-16 exhausting hole of basic point, is being provided with interconnective groove on the upper surface of pressure head body between a row through hole.
Offer ring-shaped groove on the lower surface of above-mentioned pressure head body, above-mentioned through hole is arranged in the ring-shaped groove.
The beneficial effects of the utility model are: permeability test pressure head and rock surface and internal void crack distribution characteristics are mated more, the result more tallies with the actual situation when carrying out permeability test again.
Description of drawings
Fig. 1 is the structural representation of the utility model upper surface;
Fig. 2 is the structural representation of the utility model lower surface.
Embodiment
Below in conjunction with accompanying drawing the utility model is described: a kind of rock permeability experiment pressure head described in the utility model based on the servo test system, comprise that diameter is 50 millimeters a cylindrical pressure head body 1, the circle centre position of pressure head body 1 offers through hole 2, offering with the center of circle on the described cylindrical pressure head body 1 is radioactive 16 exhausting holes 3 of being of basic point, angle between adjacent two exhausting holes 3 is 22.5 °, between a row through hole, be provided with interconnective groove 4 on the upper surface of pressure head body 1, angle between adjacent two row's grooves is 45 °, 0.8 millimeter of ditch groove width, dark 0.3 millimeter, as shown in Figure 1.
Offer four road ring-shaped grooves 5 on the lower surface of above-mentioned pressure head body 1, through hole 3 is positioned at ring-shaped groove 5,0.8 millimeter of ditch groove width, and dark 0.3 millimeter, as shown in Figure 2.
Certainly, protection domain of the present utility model is not limited to the foregoing description, so long as those of ordinary skill in the art is through creatively improving, and just should be within protection domain of the present utility model.
Claims (2)
1, tests pressure head based on the rock permeability of servo test system, comprise cylindrical pressure head body, the circle centre position of pressure head body offers through hole, it is characterized in that offering with the center of circle on the described cylindrical pressure head body is radioactive 4-16 exhausting hole of basic point, is being provided with interconnective groove on the upper surface of pressure head body between a row through hole.
