Abstract
The utility model discloses a boring elastic modulus instrument probe, which is cylinder-shaped. The utility model is divided into three sections, wherein, the front section and the rear section are outer cylinders; a cavity is arranged in the middle section; a plurality of hydrocylinders which are perpendicular to the axis of the cylinder shape are arranged in parallel in the cavity; a piston which can move along the radial direction of the cylinder is arranged in each hydrocylinder; the top of each piston is connected with a strip- shaped tip pressing board; a loading board is arranged on the strip- shaped top pressing board; the two ends of the tip pressing board are provided with a displacement sensor and a displacement sensor plate; an oil- input pipe and an oil- output pipe which are in series connection are respectively arranged on the corresponding positions of the upper end and the lower end of the hydrocylinder. The probe of the utility model can use the hydrocylinder piston in the probe to push a rigid tip pressing board and the loading board while the pressure is applied. And a symmetrical strip load can be exerted on a borehole wall rock. As the displacement sensor arranged on the tip pressing board is used to measure the borehole wall rock body and the radial deflections of the borehole wall under different pressures during the loading process.
Description
Technical field
The utility model belongs to measuring equipment, the deflection when being used for measuring the rock loading on the borehole apparatus.
Background technology
Boring elastic modulus is a kind of segmentation measurement of carrying out in the rock mass deep with below the underground water table, determines the deformation characteristic of deep rock mass and a kind of very little to the rock mass disturbance home position testing method of elastic parameter thereof.The ultimate principle of this method is: by movably popping one's head in, borehole wall is applied radial pressure, measure the deflection that rock mass produces under pressure, obtain elastic modulus, deformation modulus and the anisotropic parameters etc. of rock mass according to rock mass pressure and deformation relationship curve, be used for rock mass is carried out evaluation of classification and checks that with engineering geophysics building foundation grouting effect boring elastic modulus test belongs to the boring loading test, the probe that uses mostly is a columniform probe that is radially expanded at present.A throughput probing cumulative volume changes to determine distortion, this device structure complexity, and the sensitivity of measurement is not high, and swelling gasbag very easily damages, and consumables cost is high.
The utility model content
In view of this, the technical matters that mainly solves of the utility model be to provide a kind of simple in structure, make the highly sensitive boring elastic modulus instrument probe of measurement that plays the mould instrument.
For reaching above-mentioned technical matters, the technical solution of the utility model is achieved in that a kind of boring elastic modulus instrument probe, its profile is cylindrical, and before, during and after be divided into three sections, forward and backward two sections is urceolus, be provided with cavity in the stage casing, be set side by side with several and the perpendicular hydraulic cylinder of the cylindrical axis of described profile in the described cavity, be respectively arranged with the piston that can move along the cylindrical radial direction in described each hydraulic cylinder, each top land links to each other with the bar shaped top pressing board respectively, is provided with load plate above the bar shaped top pressing board; Described top pressing board two ends are provided with displacement transducer and displacement transducer pressing plate; With hydraulic cylinder top and bottom opposite position on be respectively arranged with the turnover oil-piping of connecting.
Described being positioned at also is provided with outside surface on the cavity place load plate and is circular-arc cover cap.
The technique effect that the utility model reaches is as follows:
Use boring elastic modulus instrument probe of the present utility model, can promote the top pressing board and the load plate of a rigidity by the piston in the hydraulic cylinder in the when pressurization probe, the wall of a borehole rock is applied the band load of a symmetry, owing on the top pressing board hole wall rock mass that displacement transducer is used for measuring boring is housed, the radial-deformation when loading under the hole wall different pressures.The utility model is simple in structure, and is highly sensitive, and it is strong to adapt to the engineering-environment ability, can satisfy rock mass mechanics parameter testing requirement, and can be used for having the heterogeneous rock mass of joint fissure.
Description of drawings
Fig. 1 is the lateral cross section cut-away view of the utility model probe;
Embodiment
As shown in Figure 1, be boring elastic modulus instrument probe of the present utility model cross section cut-away view, be one and be installed on the drilling hole type probe that plays cylindrical radial distortion on the mould instrument, be used for engineering site and determine elastic modulus of rock, be applicable to the rock mass that hard complete sum is more complete.Boring elastic modulus instrument mainly is made up of compression system and displacement test system, and probe of the present utility model is that the deflection on the compression system is measured equipment.
Before, during and after boring elastic modulus instrument probe of the present utility model is divided into three sections, forward and backward two sections is urceolus 1,8, be provided with cavity in the stage casing, be provided with in this cavity and play mould instrument main part 2, also be provided with side by side in the cavity 3 connection oil pumps and with the perpendicular hydraulic cylinder 4 of the cylindrical axis of profile, be respectively arranged with the piston that can move along the cylindrical radial direction in each hydraulic cylinder.The top land of hydraulic cylinder 4 the be sticked top pressing board 6 and the load plate 5 of bar shaped, the two ends of top pressing board 6 are provided with displacement transducer and displacement transducer pressing plate 3.Make the piston of 3 hydraulic cylinders 4 in the probe promote the top pressing board 6 and the load plate 5 of a rigidity by pressurization during test, the wall of a borehole rock is applied the band load of a symmetry, owing on the top pressing board 6 the hole wall rock mass that displacement transducer is used for measuring boring is housed, the radial-deformation when loading under the hole wall different pressures.With hydraulic cylinder 4 top and bottom opposite positions on be respectively arranged with the turnover oil- piping 9,11 of connecting.Be positioned at and be provided with outside surface on the cavity place load plate and be circular-arc cover cap, play a protective role.Boring elastic modulus instrument probe of the present utility model is simple in structure, and is highly sensitive, and can be used for having the heterogeneous rock mass of joint fissure.
The above only is preferred embodiment of the present utility model, non-limiting protection domain of the present utility model.
