Description
Technical field
The utility model relates to the deformation observation of highway soft soil roadbed, is a kind of soft visual fixedly tiltmeter.
Background technology
Be monitoring embankment stability and evaluation ground treatment effect, the position of being everlasting about side slope of embankment toe or gutter outer rim 1.0m suitable for reading is buried the development that tiltmeter is measured the displacement of roadbed deep horizontal underground.Tiltmeter is a kind of in-situ monitoring instrument of measuring the boring horizontal shift; Requirement is holed to the enough degree of depth of hard stratum and pore-forming degree of tilt and is not more than 1 °; Bury the deviational survey pipe again underground; During test deviational survey pipe induction direction is aimed in the horizontal shift direction guide groove, clinometer is slipped into stable back, the pipe end gently survey its reading, the every survey at a distance from 0.5m read once.Measuring the horizontal shift of embankment side direction with this method has certain limitation, because the rigidity of deviational survey pipe tubing is far longer than saturated soft soil, causes weak soil and the deviational survey pipe can not compatible deformation and observational error greatly occurs.In dam and vertical shaft deviational survey; Plumb line coordinator is a kind of observation instrument of maturation; Its principle be through measure vertical line and fixedly the distance of punctuate observe degree of tilt; Existing all kinds of plumb line coordinators are widely used in the engineering safety monitoring, but owing to do not develop suitable deviational survey pipe, these class methods can't be used for the horizontal displacement observation of roadbed side slope at present.
The utility model content
The utility model technical matters to be solved provides a kind of soft visual fixedly tiltmeter that can accurately measure the horizontal shift of the saturated soft soil roadbed deep soil body.
In order to solve the problems of the technologies described above; The soft visual fixedly tiltmeter that the utility model provides; Form by soft stake and computing machine shooting visible system; The structure of described soft stake is: between cup dolly and stake ceiling hold, be connected with spring steel reinforcement support body and form cylindrical flexible support with the support constraining rod; The diameter of waterproof geotextile and described waterproof geotextile that is sealedly connected with described spring steel reinforcement support body of parcel and described support constraining rod in described cup dolly and stake between the ceiling hold is bigger slightly than cylindrical flexible support diameter; In described waterproof geotextile, be full of liquid is arranged; Stake end observed object point at the position, the center of circle of described cup dolly is provided with a vertical line, and the described vertical line other end links to each other with the center of circular kickboard bottom surface, and the diameter of described circular kickboard is less than the internal diameter of described spring steel reinforcement support body; The end face center of described circular kickboard is provided with the pile bottom settlements observation point, and described stake ceiling hold is provided with directed pin; Described computing machine shooting visible system is made up of luminous coordinate and shooting two parts; Described luminous coordinate partly is made up of the luminous template and the connected control device that are arranged on described stake ceiling hold lower end; Said camera part is made up of the computing machine that 1～3 camera and the lead thereof of the upper end that is located at described stake ceiling hold connects, and described pile bottom settlements observation point touches with luminous template bottom surface mutually.
The structure of described luminous template is: the black paint envelope curve that the etching of organic glass fixed head embeds the 0.0125mm diameter constitutes coordinate line; The spacing of described coordinate line is 5mm or 10mm; The coordinate line scope is 400mm * 400mm or 800mm * 800mm; Post the flexible rainbow line that diameter is 2mm in the circumscribed circle gluing of described coordinate line, described flexible rainbow line is connected with described control device, and described control device is made up of lead, power supply, energizer and switch.

Described pile bottom settlements observation point is a conical plumb bob.
Adopt the soft visual fixedly tiltmeter of technique scheme; Because the waterproof geotextile of the outside full of liquid of soft stake is bigger slightly than cylindrical flexible support diameter; After with directional catheter the boring end and back-up sand being put in soft stake, soft stake can form the compatibility of deformation body rapidly with the borehole circumference soil body; In the process of burying underground of soft stake,, obtain the initial orientation and the origin of luminous coordinate when soft stake being put into the boring end and when being promoted to the orientation pin position of top-support, can be passed through aperture catheter center's point and conduit well azimuth and pitch angle with directional catheter.The measuring method of soft visual fixedly tiltmeter is through luminous coordinate line and the pile bottom settlements observation point of illuminating of flexible rainbow line; The computing machine that connects through camera and lead thereof in the setting of the upper end of top-support again carries out real-time photography; Gather shooting figure; The displacement observation punctuate is in the position of coordinate line at the bottom of analyzing and calculate shooting figure king-pile, and the horizontal shift value that has neither just obtained the effective observation scope roadbed of the soft visual fixedly tiltmeter deep soil body with the variable quantity of this position of period is obtained in contrast.Be to reduce error, the correction coefficient when can be on ground obtaining pile bottom settlements observation point that soft visual fixedly tiltmeter obtains and fall into different coordinate grid through actual measurement.Soft visual fixedly tiltmeter is specially adapted to the long-term observation of soft soil roadbed lateral shift of high-moisture and creep.
Advantage of the utility model and good effect:
When having drillhole inclination survey pipe deviational survey now; Need clinometer in deviational survey pipe guide rail, to slide, clinometer is actual to be the lateral shift that comes the perception soil body through the distortion of testing tubing, because the rigidity of deviational survey pipe tubing is far longer than saturated soft soil; During saturated soft soil generation micro-deformation; Deviational survey pipe tubing is not out of shape, and this has just caused saturated soft soil and the deviational survey pipe can not the compatible deformation problem, and this has just caused the generation of observational error; Especially when needing the soft soil roadbed lateral shift of long-term monitoring high-moisture or need the horizontal deformation of creep of the observation saturated soft soil roadbed deep soil body, such error is just bigger.The soft visual fixedly tiltmeter that the utility model provides utilizes the test philosophy of plumb line coordinator, and carries out real-time monitored through visual device, has overcome the error that the sensor quasi-instrument causes because of signal drift, and has very easily realized remote monitoring; The soft visual fixedly tiltmeter that the utility model provides has also overcome the test error that existing clinograph test process can not compatible deformation causes because of saturated soft soil and deviational survey pipe; Can measure the horizontal shift of the saturated soft soil soil body more accurately, be specially adapted to the long-term observation of soft soil roadbed lateral shift of high-moisture and creep.Because computing machine camera system and image interception in the utility model can adopt the common software in the conventional household PC, make this tester easier and economical.
In sum, the utility model is a kind of soft visual fixedly tiltmeter that can accurately measure the horizontal shift of the saturated soft soil roadbed deep soil body.
