Two, background technology
In large hydraulic engineering is built, carry out the radially purpose of applied voltage test of tunnel flat jack, be according to tunnel hole week suffered evenly radially the deformation values of internal water pressure and surperficial rock mass inquire into design parameters such as the deformation modulus of rock mass and unit resistance coefficient.Boring lifting jack radial loaded and tester are according to " Hydraulic and Hydro-Power Engineering rock test rules " (SL264-2001) tunnel flat jack computing formula and boundary condition requirement during radially pressurization is tested, to distortion Δ R, calculate rock mass deformation modulus E by the surperficial overall diameter of the hole wall rock mass of the unit pressure P that acts on borehole wall, measurement by following formula
0With the resistance coefficient K of unit
0
In the formula:
μ-Poisson ratio;
R-examination hole radius;
φ-distortion correction factor.
The at present domestic above-mentioned parameter that obtains mainly is to adopt radially applied voltage test of tunnel flat jack, excavation test hole, processing experiment equipment, and the installation and checkout of equipment etc. wastes time and energy, and testing expenses reach hundreds thousand of (not containing excavation test hole expense), and experimentation cost is very high; And the test section rock mass need manually add and cut a hole into round hole, deposit concrete piece, and reaction frame and testing tool equipment that pressure-bearing is installed, and deposit concrete and equipment installation procedure be complexity very; Blasting Excavation test hole causes the tunnel country rock to be disturbed, bigger to the test result influence, the installation of environmental baseline such as temperature, humidity and testing apparatus also has to a certain degree influence to test result in the tunnel in addition, and the restriction of tested equipment, can't carry out full section to load; Test normally needs with people more than 20, and the test period is longer, and the time spent reaches 2-3 month (time that does not contain excavation test hole), and the participation testing crew is many, the time is long, efficient is low, thus its improvement and innovate imperative.
Three, utility model content
At above-mentioned situation, for overcoming the defective of prior art, the purpose of the utility model just provides a kind of boring lifting jack radial loaded and tester, the test of carrying out at tunnel changed in the boring finish, can effectively solve the testing expenses height like this, troublesome poeration, test period is long, inefficient problem, the technical scheme of its solution is: include oil cylinder, displacement transducer and communication cable, oil-feed and oil return oil nozzle are arranged on the oil cylinder, the oil cylinder periphery is evenly equipped with and stretches into in-oil cylinder horizontal piston, on each horizontal piston outer end bearing plate is housed, constitute the jack structure of a shared oil cylinder, the displacement transducer terminal box is equipped with at the center in the closed chamber of oil cylinder inner face, be equipped with on the displacement transducer terminal box and the corresponding displacement transducer of each horizontal piston, the displacement transducer terminal box picks out the outside through communication cable.The utility model novel structure, simple, easy to use, expense is low, saving of work and time, efficient height, test accurately, be the radially innovation on the pressurized equipment.
