Abstract
The utility model relates to an on-water floating platform standard penetration test measuring and recording standard surveying ruler which comprises a fixing sleeve arranged below a mud face. The upper end of the fixing sleeve penetrates through a drilling platform, a base is fixedly arranged on the upper portion of the fixing sleeve, a surveying ruler main rod is arranged on the base, and a sliding surveying ruler is arranged on the upper portion of the surveying ruler main rod. The on-water floating platform standard penetration test measuring and recording standard surveying ruler removes penetration errors of a standard penetration test due to vertical fluctuation of an on-water floating platform, improves test accuracy, guarantees test quality and accordingly improves reconnaissance quality.
Description
Technical field
The utility model relates to a kind of benchmark scale, and particularly note benchmark scale is surveyed in a kind of floating platform standard penetration test waterborne.
Background technology
Standard penetration test is widely used in the geological drilling process at present as intensity, compactness and the inhomogeneity a kind of important and general test method of determining soil layer.When adopting floating platform drilling operation waterborne, especially on the river that does not have shielding, particularly during operation on the sea, owing to influenced by morning and evening tides, wave etc., the floating platform of probing teetertotters, and the drilling tool drilling rod rises and falls with platform and plays pendulum, the test reading datum is difficult for grasping, to directly influence accuracy of reading, and cause the pile penetration distortion situation of standard penetration test serious, influence is to the judgement of soil layer property.
Understand in depth by many-side, at present domestic still do not have a benchmark scale that the drilling platform that floats in the waters is used for surveying note standard penetration test pile penetration, the determine general execute-in-place skilled worker of dependence and technician's experience of test pile penetration are judged, error is difficult to avoid, and the stormy waves floating is more big, and error is also more big.
Summary of the invention
Technical problem to be solved in the utility model is to improve standard penetration test pile penetration waterborne to survey the accuracy of remembering and provide a kind of can the adaptation to drill the waterborne floating platform standard penetration test survey note benchmark scale that big, the floating yo-yo working condition of platform of stormy waves is measured on the water.
The utility model is that the technical scheme that the problem of the above-mentioned proposition of solution adopts is: note benchmark scale is surveyed in floating platform standard penetration test waterborne, comprise and be arranged at the following fixed sleeving of mud face, the fixed sleeving upper end passes offshore boring island, described fixed sleeving top is set with pedestal, pedestal is provided with the scale mobile jib, and scale mobile jib top is provided with slide scale.
Press such scheme, described pedestal is fastened on the outer rim of the sleeve opening on fixed sleeving top.
Press such scheme, described scale mobile jib is fixed on the pedestal by interior screw thread rotation.
Press such scheme, described slide scale is fixed on the scale mobile jib by the pressing fixing means.
The beneficial effects of the utility model are: 1, be convenient to observation and metering.2, with using with slotting, conveniently assemble and disassemble.3, simple in structure, material is solid, scale is not easy to wear, can use repeatedly.4, simple in structure, cheap, easy to process.

Among the figure: 1, pedestal, 2, the scale mobile jib, 3, slide scale, 4, fixed sleeving, 5, telescoping tube, 6, the mud face, 7, the water surface, 8, drilling ship, 9, drilling platform, 10, the horizontal scale bar, 11, sleeve opening, 12, drilling rod.
The specific embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, note benchmark scale is surveyed in floating platform standard penetration test waterborne, fixed sleeving 4 general 1.5m-2.0m one joints, plug into by internal thread, the mud face is inserted in the bottom, and until the face of being fixed on 6 times, top connects drilling platform 9 with the sledgehammer hammering; About the general 1.5m of telescoping tube 5 length, diameter is slightly thinner than fixed sleeving 4, can inject 4 li of fixed sleevings, is stuck in by iron plate on the girder steel of drilling platform 9.When the hull of drilling ship 8 fluctuated along with wave, fixed sleeving 4 maintained static, and telescoping tube 5 is with the hull dipping and heaving of drilling ship 8, but connect with fixed sleeving 4; Fixed sleeving 4 is the floating unique reference points of platform of whole drilling on waterways, telescoping tube 5 inside are provided with drilling rod 12, the outer rim engaging of the upper sleeve mouth of fixed sleeving 4 has pedestal 1, be vertically installed with scale mobile jib 2 on the pedestal 1, scale mobile jib 2 is fixed on the pedestal 1 by interior screw thread rotation mode, scale mobile jib 2 and drilling rod 12 keeping parallelisms, scale mobile jib 2 tops are provided with slide scale 3, the spacing normative reference penetration test length of the horizontal scale bar 10 on the length of slide scale 3 and the slide scale 3 is made, slide scale 3 is fixed on the scale mobile jib 2 by the pressing fixing means, slide up and down the arrival testing position and fix, horizontal scale bar 10 puts down and can begin to carry out standard penetration test.
The utility model beneficial effect is: this scale is surveyed note accurately, is simple and easy to usefulness, load and unload quick and convenient, cheap, long service life, applied widely, when floating platform fluctuates big rise and fall up and down on the water, reach the purpose that the standard penetration test pile penetration is remembered in accurate survey.Floating platform standard penetration test waterborne is surveyed note benchmark scale and has been eliminated the standard penetration test pile penetration error that fluctuates up and down and cause because of floating platform waterborne, has improved the accuracy of test, has guaranteed test mass, thereby has improved the prospecting quality.
The above; only being preferred embodiment of the present utility model, is not that the utility model is done any pro forma restriction, and those skilled in the art utilize the technology contents of above-mentioned announcement to make a little simple modification; equivalent variations or modification all drop in the protection domain of the present utility model.
