Abstract
The invention discloses a physical settlement meter with high measurement precision. The physical settlement meter comprises a fixed bottom plate (3), measurement rods (1) arranged in the center of the fixed bottom plate (3), and a PVC (polyvinyl chloride) protection tube (2) sleeved outside the measurement rods (1), wherein the measurement rods (1) and the PVC protection tube (2) are parallel to a center axial line, the measurement rods (1) are connected with the fixed bottom plate (3) through a thread, the measurement rods (1) are vertical to the fixed bottom plate (3) and are mutually connected, the length of the PVC protection tube (2) is slightly less than that of the measurement rods (1), parts of the measurement rods (1), which are exposed outside the PVC protection tube (2) are sequentially provided with uniform scale lines, and the scale lines are vertical to the length direction of the measurement rods (1). The physical settlement meter adopting the structure has the advantages of high structural precision, little influences by outside factors, low price, and accurate and rapid selection of a reference point.
Description
Technical field
The present invention relates to a kind of sedimentometer, be specifically related to the physical settlement gauge that a kind of measuring accuracy is high.
Background technology
What sedimentometer generally adopted at present is electromagnetic type sedimentometer, the sensor adopting is to design according to electromagnetic induction principle, magnetic induction sedimentation ring is imbedded to underground each point position to be measured by bore mode in advance, when sensor is during by magnetic induction ring, produce electromagnetic induction signal and deliver to ground instrument demonstration, send audible and visible alarm simultaneously.Read the scale numerical value of corresponding steel ruler on the gauge point of aperture, be the degree of depth of sedimentation ring.Each measured value and last time measured value subtract each other the settling amount that is this measuring point.The shortcoming of this sedimentometer is that precision is too low, is easily subject to extraneous factor and disturbs, and price is higher.And in measuring process, when setting up reference point by transit, owing to there is no scale on sedimentometer, tightly with visual inspection, in judgement, there is error unavoidably, and make the inconsequent of choosing of reference point, affect observed result.Thereby the settling data drawing has error, also unfavorable to the monitoring construction in later stage.
Summary of the invention
The present invention has overcome the deficiencies in the prior art, and the physical settlement gauge that a kind of measuring accuracy is high is provided, and has solved precision too low, is easily subject to extraneous factor and disturbs, and price is higher and choose the inaccurate shortcoming of reference point.
For solving above-mentioned technical matters, the present invention is by the following technical solutions: the physical settlement gauge that a kind of measuring accuracy is high, by fixed base plate, the sounding rod that is positioned at fixed base plate center forms with the PVC protection tube that is enclosed within corresponding sounding rod outside, sounding rod and PVC protection tube are parallel to central axis, described sounding rod and fixed base plate are threaded connection, sounding rod is perpendicular to fixed base plate, between sounding rod, can interconnect, the length of described PVC protection tube is slightly less than the length of sounding rod, the part that described sounding rod exposes PVC protection tube is distributed with uniform scale mark successively, scale mark is vertical with sounding rod length direction.
Above-mentioned sounding rod be shaped as cylinder, at least need one.
Above-mentioned sounding rod during more than one, uprightly links together many sounding rods by screw thread head and the tail successively.
Scale mark on above-mentioned sounding rod is red, and the part of just having exposed PVC protection tube from sounding rod starts from the bottom up label successively.
Above-mentioned first scale mark of sounding rod starts downwards indexing successively, and institute's indexing length and sounding rod expose part equal in length of PVC protection tube.
The diameter of above-mentioned PVC protection tube is slightly larger than the diameter of sounding rod and can freely takes out and be enclosed within on sounding rod.
The length of above-mentioned fixed base plate and wide equate and the ratio range of the length of height and fixed base plate between 1/6 ∽ 1/4.
Compared with prior art, the invention has the beneficial effects as follows:
(1) the present invention, by having PVC protection tube in sounding rod outer cover, because its pliability is good, is difficult for crisp; nontoxic pollution-free, the holding time is long, can play the impact of factor on sedimentometer such as preventing filler, water; be that measurement result is more accurate, improve the serviceable life of sounding rod.
(2) the present invention is provided with scale on sounding rod, when setting up reference point by transit, more easily locates the accurate location of the reference point of wanting, and records, and when need identical reference point next time, also more easily finds, and reduces hunting time.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Number in the figure is expressed as: 1, sounding rod; 2, PVC protection tube; 3, fixed base plate.
Embodiment
Below in conjunction with accompanying drawing 1, the present invention is further elaborated.The present invention is comprised of fixed base plate 3, the PVC protection tube 2 that is positioned at the sounding rod 1 of fixed base plate 3 centers and is enclosed within corresponding sounding rod 1 outside; sounding rod 1 and PVC protection tube 2 are parallel to central axis; described sounding rod 1 is threaded connection with fixed base plate 3; sounding rod 1 is perpendicular to fixed base plate 3; between sounding rod 1, can interconnect; the length of described PVC protection tube 2 is slightly less than the length of sounding rod 1; the part that described sounding rod 1 exposes PVC protection tube 2 is distributed with uniform scale mark successively, and scale mark is vertical with sounding rod 1 length direction.The diameter of PVC protection tube 2 is slightly larger than the diameter of sounding rod 1 and can freely takes out and be enclosed within on sounding rod 1.Sounding rod 1 be shaped as cylinder, at least need one, sounding rod 1 during more than one, uprightly links together many sounding rods 1 by screw thread head and the tail successively.Scale mark on sounding rod 1 is red, and the part of just having exposed PVC protection tube 2 from sounding rod 1 starts from the bottom up label successively, and the diameter of PVC protection tube 2 is slightly larger than the diameter of sounding rod 1 and can freely takes out and be enclosed within on sounding rod 1.The length of fixed base plate 3 and wide equate and the ratio range of the length of height and fixed base plate 3 between 1/6 ∽ 1/4.As mentioned above, can realize well the present invention.
The course of work of the present invention is as follows: in subgrade construction engineering, sedimentometer is embedded in different depth place roadbed filling, when road surface pavement, the connecting link that reserves an aperture ，Shi the top for sedimentometer can expose road surface.Near the roadbed section of observation sedimentation, by transit, set up two permanent reference points, reference point is chosen by the scale above reference measure bar and is determined, observational record sedimentometer elemental height, when highway is open to traffic later six months, 1 year, 2 years, survey record sedimentometer, from the height of datum line, by the comparison with initial elevation, can be known the sedimentation that roadbed different depth occurs again respectively.
As mentioned above, can realize well the present invention.
