Description

Physics formula sedimentometer
Technical field
The utility model relates to measuring equipment, is specifically related to a kind of physics formula sedimentometer.
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 by bore mode in advance, when sensor during by the magnetic induction ring, produce electromagnetic induction signal and deliver to the 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 subtracts each other the settling amount that is this measuring point with measured value last time.The shortcoming of this electromagnetic type sedimentometer is: precision is low excessively, be subjected to extraneous factor easily and disturb, and price is higher.
For example: notification number is the Chinese utility model patent of CN201567560U, disclose a kind of utility model and related to a kind of digital sedimentation device, comprise the definite stake of sedimentometer and reference point, described sedimentometer comprises that one surveys pipe, an end outside of surveying pipe is provided with the settlement cell of band protective cover, survey tube end in the settlement cell is sealed and installed with pressure transducer, and pressure transducer is connected with data presentation device by lead; Survey the pipe other end and be communicated with, and this end is managed in survey and described lead all is fixed in the definite stake of reference point with atmosphere.This utility model promptly is typically to utilize the sensor measurement settling amount, also just can't avoid its intrinsic problem of interference structure than complicated and selling at exorbitant prices that be subject to.
The utility model content
The utility model has overcome the deficiencies in the prior art, has made a kind of physics formula sedimentometer, and it is simple in structure, easy for installation, and measuring method is also simple, and precision is higher.
For solving above-mentioned technical matters, the utility model by the following technical solutions:
A kind of physics formula sedimentometer; comprise base plate, at least one connecting link and with the same number of connecting link protection tube of connecting link; connecting link vertically is fixed on the base plate, and the internal diameter of connecting link protection tube is bigger slightly than the external diameter of connecting link, and the connecting link protection tube is enclosed within its inside with connecting link.
Further technical scheme is:
Described connecting link is that a long straight-bar or be fixedly connected sequentially from beginning to end by many short straight rods forms.
Described connecting link is installed on the base plate by thread connecting mode.
Described connecting link has one, and is fixed in the middle part of base plate.
Described connecting link has three, and shape is arranged in base plate in line.
Described connecting link has three, is in triangular distribution to be arranged in base plate.
Compared with prior art, the beneficial effects of the utility model are: the utility model is mainly used in beneath each the delaminating deposition amount such as ground, tailing dam, foundation ditch, dyke of measuring.According to the variation of test data, can calculate sedimentation trend, analyze its stability, monitoring work progress etc.It is simple in structure, easy for installation, cost is lower, and measuring accuracy is higher.
Description of drawings
Fig. 1 installs and uses synoptic diagram for the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further elaborated.
Embodiment 1:
As shown in Figure 1; a kind of physics formula sedimentometer, comprise base plate 1, connecting link 2 and with a connecting link protection tube 3, connecting link 2 vertically is fixed on the middle part of base plate 1; and the internal diameter of connecting link protection tube 3 is bigger slightly than the external diameter of connecting link 2, and connecting link protection tube 3 is enclosed within its inside with connecting link 2.The length of connecting link 2 determines according to the design length of embedment, can be that a long straight-bar or be fixedly connected sequentially from beginning to end by many short straight rods forms.Connecting link 2 is installed on the base plate 1 by thread connecting mode in the present embodiment, and we also can link together them by other common fixedly connected modes certainly.
Embodiment 2
The places different with embodiment 1 are that connecting link 2 has three, and shape is arranged on the base plate 1 in line.
Embodiment 3
The places different with embodiment 2 are that three connecting links 2 are in triangular distribution and are arranged on the base plate 1.
Introduce installation method of the present utility model and measuring method below again.
In the subgrade construction engineering, physics formula sedimentometer is imbedded in the roadbed filling 5 by projected depth, the pvc pipe that is slightly larger than connecting link 2 with internal diameter puts connecting link 2, to prevent of the influence of factors such as filler, water to connecting link 2, when road surface pavement, reserve an aperture for connecting link 2, make the connecting link 2 of the top can expose the road surface.By connecting link 2 being embedded in roadbed different depth place, the sedimentation that just can record the roadbed different depth.
Measuring method is as follows:
(1) near the roadbed section of observation sedimentation, sets up two permanent reference points by transit;
(2) by reference point, the initial elevation of observational record physics formula sedimentometer;
(3) when highway is open to traffic later six months, 1 year, 2 years, the elevation of survey record sedimentometer once more respectively, by with the comparison of initial elevation, promptly know the sedimentation that the roadbed different depth takes place.
