Description
Technical field
The utility model relates to the pile foundation detection range, is specifically related to a kind of bearing capacity of single pile detection reference device.
Background technology
One of main purpose that pile foundation detects is to determine bearing capacity of single pile, and the accurate test of bearing capacity of single pile all plays a part very important for the design of design of all kinds of building foundations and even superstructure.Detect principle and be with jack etc. pile foundation top (promptly measuring face) applied downward active force, the settling amount of measurement face under different active forces then reflected the pile foundation bearing capacity of single pile.The reading of dial gage changes can reflect measurement face settling amount, thus to guarantee in testing process, fixedly the datum line beam of dial gage must stablize, indeformable, otherwise the detection data can not truly reflect the pile foundation bearing capacity of single pile.Therefore, suitable testing equipment and correct mounting method play very important influence to the authenticity of result of the test.
For guaranteeing measuring accuracy, datum line beam should firmly be erected on the reference pegs, referring to Fig. 1, generally should select shaped steel for use from engineering test angle datum line beam 1, and shaped steel is convenient to install Magnetic gauge stand 2, and stiffness is big, and consistent being convenient to of shape processed.Datum line beam 1 main i iron (worker 12#) and the channel-section steel (126 * 53 * 5.5) of using, the steel pipe that scaffold is used is put up at the scene of also can using sometimes.Displacement dial gage 4 is fixed on the Magnetic gauge stand 2 by connecting rod 3, and Magnetic gauge stand 2 is fixed on the datum line beam 1, and dial gage 4 measures 5 displacements of measurement face, or the displacement measuring instrument that adopts resolution ratio to be better than 0.01mm is measured.When adopting shaped steel to do datum line beam, adopt following measure, prevent that it from influencing accuracy of detection, an end of datum line beam is fixed and the other end freely supports; Prevent datum line beam to be subjected to the sunlight direct irradiation and set up sunshade; Near the datum line beam high-power illumination and heating system can not be set; Also heat-barrier material such as available polystyrene wraps up datum line beam, to eliminate temperature effect.
Datum line beam is a shaped steel in the prior art scheme, and test mostly is open-air large-scale experiment, and datum line beam length is big, and therefore general 3-4m is subjected to temperature difference influence big.Generally all more than diel, because factors such as Exposure to Sunlight, the temperature difference cause rigidity datum line beam repeated deformation, influence accuracy of detection detection time, makes troubles to calculating correction values.Though adopt above measure to prevent from influence accuracy of detection when detecting the shortcomings below these measures exist: limited by site condition during being erected with of sunshade, area coverage is limited; The heat-barrier material role is limited; And when day and night temperature was big, the temperature deformation of rigidity datum line beam was inevitable, when detecting data preparation, utilized experience to carry out the data adjustment, had influenced the authenticity of testing result to a certain extent.
Summary of the invention
The utility model is in order to solve the deficiencies in the prior art, provide a kind of easy for installation, move light, as to improve accuracy of detection bearing capacity of single pile detection reference device.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of bearing capacity of single pile detection reference device, comprise datum line beam, dial gage and connecting rod, described connecting rod one end links to each other with dial gage, the material of described datum line beam is wooden, described datum line beam is provided with at least one installing hole, and the described connecting rod other end is fixedly installed in the installing hole.
Fixedly install two-sided threaded connector in the described installing hole, the described connecting rod other end is by the fixedly connected two-sided threaded connector of screw thread.
Described datum line beam cross section is rectangle or square.
Described datum line beam cross section is 150 * 150mm, and length is 3-4m.
The side of described datum line beam is arranged side by side 6-8 installing hole, and the center to center distance of adjacent installing hole is 100-150mm.
Compared with prior art, the utility model adopts wooden profile material to do datum line beam, has overcome the steel section bar drawback that deforms affected by environment, has improved measuring accuracy, can make datum line beam really plays provides benchmark for settlement measurement effect.Simultaneously the utility model has also been considered supporting with conventional dial gage, have easy for installation, move light, easy and simple to handle, laborsaving advantage; Also saved the expense of setting up sunshade and purchasing Magnetic gauge stand thereupon.
