Detailed Product Description: | K30 type plate load tester (plate load tester, plate load tester) applicable to crude, testing foundation coefficient of roadbed, grass and other fine-grained soil and soil compaction after filling can also be used to calculate uniform foundation soil deformation modulus the amount. Stress and deformation of soil tests to determine the foundation coefficient railway, highway roadbed, grass and the like. Plate load tester technical parameters 1, the load plate diameter: 300mm 2, jack load capacity range: 0 ~ 30T 3, extremely heavy items travel: 120mm 4, measurement bridge span: 3000mm 5, manual pump rated pressure: 70Mpa 6, stress testing range : 0 ~ 40Mpa 7, displacement measuring range: 0 ~ 10mm K30 plate loading test instrument calibration. First, the technical requirements 1.1 jack: 100kN, asked not to leak. 1.2 pressure gauge: Range 0 ~ 60Mpa, regularly inspected. 1.3 dial indicator: Range 0 ~ 30mm, dividing the value of 0.01mm, regularly inspected. 1.4 bearing plate: diameter 300mm, made of steel, and the base is connected to the jack, no deformation within the force range. Two, K30 plate loading tester (plate load tester, plate load tester) check items and condition of the press: 100kN, dividing the value of 50N. Third, check the range of 3.1 to stress test gauge calibration readings by 10 to 12 points, 5 Mpa is level. 3.2 High-pressure hose with quick connector with the top pick (jack), pressure gauge and horizontal pump with three whole body into a whole series, and the top pick was placed under 100kN press pressure plate. 3.3 The top picks piston playing 1 ~ 2cm, and then start the press, the upper bearing plate of the press plate in contact with the top surface of the piston top picks. 3.4 press for reaction force, with a hand pump pressure, step by step calibration calibration load rating according to the division. When the pressure force should be uniform in order to avoid hydraulic shock caused by the pressure gauge beating. 3.5 Fixed gauge calibration grade reading, recording a top force gauge dial pointer corresponds reading. 3.6 Calibration repeat 2 or 3 times, at least twice a calibration data taken mathematical statistics. Four, K30 plate loading tester (plate load tester, plate load tester) check results of the processing power of the press to establish a top reading the regression equation, complete calibration records. K30 plate loading tester field testing procedures should be flat surface and use a brush to sweep the loose soil. When in the slope, it should load plate support surface made of a horizontal plane. 1. Set plate load plate (1) Load the plate placed on the test ground, should make good contact with the load board ground, laying a thin layer of dried sand (2 to 3 mm) or gypsum putty, if necessary, when the plaster putty When doing cushion should load plate in the bottom surface of a layer of film wiping, and then load plate placed on the plaster layer, turning left and right load plate and gently hit the top, so that full contact with the ground at the same time can make use of Level load adjustment board level. (2) the load-bearing part of the anti-power plant placed in load plate side, and to brake, the anchor reaction force from the load device must 1m beyond the outside edge of the plate. (3) the jack is placed on the anti-load power plant following the board, you can use extensions and by adjusting the screw, so close to the jack on the top of the tee carrying the anti-power plant site, the assembly should not keep the jack vertical tilt (4) placement test bridge, measuring bridge support base should be set at a distance outside edge of the load plate and anti-power plant support point than 1m, placed measuring table must be symmetrical to each other, and should be kept equidistant and load center of the plate. 2. Load test (1) is a solid load boards, advance plus 0.01MPa load about 30s, until stable removing load, the indicator reading to zero or read the dial indicator readings as subsidence initial readings. 0.04MPa of increments, step by step loading for each additional head of load, when 1min settlement amount not greater than the level load generated 1% of the settlement amount, intensity and subsidence read loads of reading, then increase under a load. (2) when the total amount of subsidence exceeds a predetermined reference value (1.25㎜), or load strength than the estimated actual site maximum contact pressure, or reaches ground yield point test can be terminated. |
