Description
Technical field
The utility model relates to a kind of sedimentometer, is specifically related to the high physics formula sedimentometer of a kind of measuring accuracy.
Background technology
What sedimentometer generally adopted at present is the electromagnetic type sedimentometer; The sensor that is adopted is to design according to electromagnetic induction principle; Magnetic induction sedimentation ring is imbedded underground each point position to be measured through bore mode in advance; When sensor during through the magnetic induction ring, produce electromagnetic induction signal and deliver to ground instrument and show, 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 subtracts each other the settling amount that is this measuring point with measured value last time.The shortcoming of this sedimentometer is that precision is low excessively, receives extraneous factor easily and disturbs, and price is higher.And in measuring process, when setting up reference point,,, on judging, have error unavoidably tightly with visual inspection owing to do not have scale on the sedimentometer through transit, making the inconsequent of choosing of reference point influences observed result.Thereby the settling data that draws has error, and is also unfavorable to the monitoring construction in later stage.
The utility model content
The utility model has overcome the deficiency of prior art, provides a kind of measuring accuracy high physics formula sedimentometer, and it is low excessively to have solved precision, receive extraneous factor easily and disturb, price higher with choose the inaccurate shortcoming of reference point.
For solving above-mentioned technical matters; The utility model adopts following technical scheme: the physics formula sedimentometer that a kind of measuring accuracy is high, and by fixed base plate, be positioned at the sounding rod of fixed base plate center and be enclosed within the outside PVC protection tube of corresponding sounding rod and form, sounding rod and PVC protection tube are parallel to central axis; Said sounding rod and fixed base plate are through being threaded; Sounding rod can interconnect between the sounding rod perpendicular to fixed base plate, and the length of said PVC protection tube is slightly less than the length of sounding rod; The part that said sounding rod exposes the PVC protection tube is distributed with uniform scale mark successively, and scale mark is vertical with the sounding rod length direction.
Above-mentioned sounding rod be shaped as cylinder, need one at least.
Above-mentioned sounding rod uprightly links together many sounding rods through the screw thread head and the tail during more than one successively.
Scale mark on the above-mentioned sounding rod is red, and the part of just having exposed the PVC protection tube from sounding rod begins from the bottom up label successively.
First scale mark of above-mentioned sounding rod begins downwards indexing successively, and institute's indexing length and sounding rod expose the equal in length of the part 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 the 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 beneficial effect of the utility model is:
(1) the utility model because its pliability is good, is difficult for crisp through being with the PVC protection tube in the sounding rod outside; Nontoxic pollution-free, the holding time is long, can play the influence to sedimentometer such as the factor that prevents filler, water; Be that measurement result is more accurate, improve the serviceable life of sounding rod.
(2) the utility model sounding rod is provided with scale, when setting up reference point through transit, more is prone to the accurate position of the location reference point of wanting, and notes, and when need identical reference point next time, also finds more easily, reduces hunting time.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Label is expressed as respectively among the figure: 1, sounding rod; 2, PVC protection tube; 3, fixed base plate.
Embodiment
Do further to set forth below in conjunction with 1 pair of the utility model of accompanying drawing.The utility model by fixed base plate 3, be positioned at the sounding rod 1 of fixed base plate 3 centers and be enclosed within corresponding sounding rod 1 outside PVC protection tube 2 and form; Sounding rod 1 is parallel to central axis with PVC protection tube 2; Said sounding rod 1 and fixed base plate 3 are through being threaded; Sounding rod 1 can interconnect between the sounding rod 1 perpendicular to fixed base plate 3, and the length of said PVC protection tube 2 is slightly less than the length of sounding rod 1; The part that said 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 the sounding rod 1.Sounding rod 1 be shaped as cylinder, need one at least, sounding rod 1 uprightly links together many sounding rods 1 through screw thread during more than one from beginning to end successively.Scale mark on the sounding rod 1 is red, and the part of just having exposed PVC protection tube 2 from sounding rod 1 begins 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 the 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.
The course of work of the utility model is following: in the subgrade construction engineering, sedimentometer is embedded in the different depth place roadbed filling, when road surface pavement, reserves an aperture for sedimentometer, make the connecting link of the top can expose the road surface.Near the roadbed section of observation sedimentation; Set up two permanent reference points through transit, reference point is chosen through the scale above the reference measure bar and is confirmed, observational record sedimentometer elemental height; When highway is open to traffic later six months, 1 year, 2 years; Respectively once more the survey record sedimentometer from the height of datum line, through with the comparison of initial elevation, promptly know the sedimentation that the roadbed different depth takes place.
As stated, then can realize the utility model well.
