Abstract
A slope section lifting monitoring device comprises a measuring tube. The upper end of the measuring tube is fixed on a seat plate, a plurality of limiting blocks are further arranged at the lower portion of the upper end of the measuring tube, a sleeve is arranged out of the measuring tube, a magnetic seat of a measuring frame is positioned on the seat plate, a deformation meter is arranged between a dowel bar of the measuring frame and a measuring pier, the measuring pier is a square concrete pier, a glass plate is arranged on the top surface of the measuring pier, and the upper surface of the glass plate is in contact with a measuring pointer of the deformation meter. The slope section lifting monitoring device is used for continuously monitoring whether a stratum lifts in a grouting construction process of a slope section, is visual, timely and accurate in monitoring data and is wholly simple, economical and applicable.
Description
Technical field
The utility model relates to the stratum monitoring technical field, particularly a kind ofly is applicable to monitor the device that sloping area ground lifts.
Background technology
At present, in the construction of dam foundation grouting works, especially be positioned at the grouting works construction at position, dam abutment slope, need the stratum is lifted deformation monitoring, traditional method is to adopt level gage measurement method, namely on the ground of grouting scope a plurality of fixed observer points is set, whether the elevation that then uses level gauge to measure observation point in the grouting construction process changes, thereby judge whether the stratum lifts situation, the shortcoming that this method exists is, survey crew must continuous measurement in whole grouting construction process, otherwise just can not find in time that whether the stratum lifts phenomenon, will cause the stratum to be lifted destruction; In addition, the expense of measureing equipment is comparatively expensive, and is therefore also uneconomical.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of sloping area lift monitoring device, can be used for sloping area and whether lift phenomenon on grouting construction process continuous measurement stratum, monitored data is directly perceived, timely, accurate, and package unit is simple, economic and practical.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of sloping area lift monitoring device, comprise test tube, the upper end head of test tube is fixed with seat board, upper end bottom in test tube also is provided with the polylith limited block, test tube is equipped with sleeve pipe outward, and the magnet base of test aircraft places on the seat board, and deformation gauge is installed in the dowel bar of test aircraft and measures between the pier.
Described measurement pier is the square concrete pier, and its end face is provided with a glass plate, and the upper surface of glass plate contacts with the chaining pin of deformation gauge.
Described limited block is iron block, is fixed on the outer wall of test tube.
Described seat board is circular steel plate, and diameter is than the slightly larger in diameter of measuring staff.
The sloping area lift monitoring device that the utility model provides is used for sloping area and whether lifts phenomenon on grouting construction process continuous measurement stratum, and monitored data is directly perceived, timely, accurate, and package unit is simple, economic and practical.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is main TV structure schematic diagram of the present utility model.
The specific embodiment
Structure of the present utility model as shown in Figure 1, a kind of sloping area lift monitoring device, comprise test tube 1, the upper end of test tube 1 is fixed with seat board 2, upper end bottom in test tube 1 also is provided with polylith limited block 3, outside the test tube 1 sleeve pipe 4 is installed, the magnet base 5-1 of test aircraft 5 places on the seat board 2, and deformation gauge 6 is installed in the dowel bar 5-2 of test aircraft 5 and measures between the pier 7.Described measurement pier 7 is the square concrete pier, and its end face is provided with a glass plate 8, and the upper surface of glass plate 8 contacts with the chaining pin of deformation gauge 6.Described limited block 3 is iron block, is fixed on the outer wall of test tube 1.Described seat board 2 is circular steel plate, and diameter is than the slightly larger in diameter of measuring staff 1.The limited block 3 that arranges can make test tube 1 placed in the middle, is conducive to guarantee certainty of measurement.
In the utility model, the hypomere of test tube 1 is anchored in the boring 10 by mortar 11, and the lower end of sleeve pipe 4 is positioned at the mortar 11 end face places of boring 10, and its hypomere is filled with butter gypsum mixtures 12, and the gap backfill between its top and the borehole wall has fine sand 9.
The utility model installation process:
1) hole 10 at slope first according to designing requirement, adopt mortar 11 that test tube 1 is anchored in the boring, the length of mortar section is controlled at about 20cm; After the mortar initial set, under the hole, enter butter gypsum mixtures 12, its length also is controlled at about 20cm, then is lowered to sleeve pipe 4 in the hole, and the purpose of butter gypsum mixtures 12 is set, and is convenient to can extract easily sleeve pipe 4 after the completion.
2) on the ground of distance boring 50cm, adopt concrete for making one square measurement pier 7, and the surface embeds a glass plate 8 thereon, the upper surface of glass plate 8 flushes with concrete surface.
3) according to the requirement of Fig. 1 test aircraft 5 and deformation gauge 6 are installed at last, deformation gauge 6 is strain meter in this example, also can use dial gauge.
4) monitoring: in filling process, if surface of stratum produces and lifts, because test tube 1 is anchored at the depths, stratum, relatively motionless, and deformation gauge 6 produces displacement, therefore will accurately demonstrate and lift numerical value, the observation personnel just can in time take preventive measures according to lifting numerical value, avoid the earth's surface to produce and lift destruction.
