Description
Technical field
The utility model belongs to roadbed monitoring field, specially a kind of induction band for subgrade settlement automatic Observation.
Background technology
Highway subgrade is especially more multiple in regional area Hydroclimate condition throughout the year by the percussion of vehicular load
It is miscellaneous, cause roadbed that sedimentation and deformation easily occurs.In recent years, with the development of transportation, vehicle flow is growing day by day, vehicle
Load also has the trend constantly increased, or even the situation that overweight car load exceedes 3 ~ 4 times of design load occurs, and these factors are tight
The operation situation of roadbed is degrading again.Sedimentation, which occurs, for roadbed will cause Uneven road suitable, influence the comfortableness and peace of vehicle operation
Quan Xing.In privileged sites, such as bridgehead position, the degree that car is jumped in conference increase is crossed in subgrade settlement, and the percussion of formation is in turn
Meeting Accelerated subsidence, forms vicious circle.The load that railway bed is subject to is bigger, and ride comfort requires higher, therefore sedimentation is wanted
Ask also tightened up.
Roadbed as shown in Figure 1, in use for some time, because the sedimentation of bottom roadbed 80 is caved in, when causing to pave the way
First basic unit 81, the second basic unit 82, the 3rd basic unit 83 follow sedimentation to be formed 85 at surfaces collapse, ultimately result in road surface 84 and are formed such as
86 at slight crack in diagram, so cause road surface 84 to destroy, influence vehicle pass-through, or even traffic accident can be caused.
At present, being generally used for the measuring method of road foundation sedimentation both at home and abroad includes：Embedded sedimentation plate, such as Fig. 2, Fig. 3 institute
Show, after the completion of the arrangement of roadbed 80, after detection meets basic unit's construction conditions, laid in the position of intermediate isolating band 87 of road
Measurement mark component as shown in Figure 3, it includes the bottom plate vertical rod 71 for being arranged on the bottom plate 70 of bottom, being vertically connected with bottom plate 70
And expose the measurement mark 72 on road surface；Then one layer is often laid, one layer of measurement mark component is put, to detect the sedimentation feelings of this layer
Condition.After the completion of road surfacing, the elevation information of periodic detection measurement mark 72, continuity data are formed, monitor sedimentation situation.Cause
If being settled for road surface, it occurs that the bottom plate 70 as shown in the right in Fig. 2 follows the situation of sedimentation, so as to feed back to measurement
On the elevation of mark 72, i.e., sedimentation D occurs for a certain basic unit, then the elevation change for representing the measurement mark 72 of the basic unit corresponds to D.
Low with upper type measuring accuracy, test automation degree is low, and can only reflect certain point（It placed bottom plate 70
Put) sedimentation change, and need pavement structure to support, can have the pre-buried measurement mark component in position, and also have for pre-buried
Construction requirement, it is cumbersome, it is more difficult to promote the use of a large area.
It is understood that resistance=resistance coefficient × length ÷ cross-sectional areas, resistance strain gage stretching, then electrical resistance wire grid elongation,
Cross-sectional area diminishes simultaneously, so resistance increases.Resistance value size it can be considered to measure resistance strain gage is come actual anti-
Answer the tensile deformation relation of resistance.
The application consideration is pre-buried pre-buried to replace measuring mark component by resistance-strain equipment, is changed by detection resistance real-time
Perceive the sedimentation change of base course.
