Under the influence of natural conditions and mankind's activity, crackle inevitably occurs in the side slope of both sides of the road, and crackle is deposited
It can cause the generation of major accident, such as in the big rainy day due to rainwash, crackle meeting induced landslide, it is therefore necessary to opposite side
Slope crackle regularly observe and monitor, if the width of crackle exceedes safe range, must just be handled in time.At present
The width measure of side slope crackle is surveyed and drawn on the spot using tape measure or square more, these measuring methods are simple and practicable, but
It is to be inaccurate to the measurement data of crack width, is especially intended to realize have very big difficulty to the continuous observation of fixing point,
Mark post need to be set to identify, personnel bring big inconvenience to field survey.
The content of the invention
The purpose of this utility model is that to overcome drawbacks described above existing in the prior art, there is provided a kind of side slope
Crack width observation device.
The utility model is achieved through the following technical solutions above-mentioned purpose, a kind of side slope crack width observation device, bag
Scale bar and reading wand are included, both are with the use of the measurement completed to crack width, it is characterised in that the scale bar is by scale
The vertical upright bar of ruler, graduated scale and concrete foundation composition, graduated scale are at right angles rigidly connected with the vertical upright bar of graduated scale, concrete
Basis is located at the vertical upright bar lower end of graduated scale, and in rigid connection；The reading wand by reading ruler, the vertical upright bar of reading ruler, split
Line width reading screw rod and concrete foundation composition, reading ruler are at right angles rigidly connected with the vertical upright bar of reading ruler, coagulation soil matrix
Plinth is located at the vertical upright bar lower end of reading ruler, and in rigid connection.
In above-mentioned technical proposal, the graduated scale is long 1000mm with graduated scale, meets maximum crack width
Measurement, the precision of scale is 1mm.
In above-mentioned technical proposal, the reading ruler is long 1000mm, and middle part is the steel plate of hollow-core construction, and the thickness of steel plate is
20mm, has preferable rigidity on the premise of guarantee is light-weight.
In above-mentioned technical proposal, the vertical upright bar of the graduated scale, reading ruler is length 800mm, the hollow steel of outside diameter 60mm
Pipe.
In above-mentioned technical proposal, the concrete foundation be the length of side be 200mm cube structure, the coagulation under the size
Earth foundation has larger contact area with bottom, upper end graduated scale, reading ruler is had stable cantilever foudation.
In above-mentioned technical proposal, the crack width reading screw rod is stretching structure, there is certain cone from root to end
Degree, can be free to slide in the hollow-core construction of the reading ruler, is locked by end nut.
In general, by the contemplated above technical scheme of the utility model compared with prior art, can reach with
Lower beneficial effect：After scale bar and reading wand are embedded in bottom, the position for adjusting a reading screw rod immobilizes, and only needs to move
Move another position of reading bolt on the scale, it is possible to realize the measurement to crack width, it is easy to use, can accurately it obtain
Crack boundary width data is taken, substantially increases the accuracy of fracture width observation.

Embodiment
As depicted in figs. 1 and 2, a kind of front view of side slope MEASUREMENT OF CRACK WIDTH device, including scale bar and reading wand；Institute
State scale bar to be made of graduated scale 4, the vertical upright bar 3 of graduated scale and concrete foundation 2, the upright bar 3 vertical with graduated scale of graduated scale 4 is in
Right angle is rigidly connected, and the plant consolidated by concrete foundation 2 is in the stratum on side slope crackle one side, graduated scale 4 and side slope basal plane 1
It is parallel；The reading wand is by 2 groups of reading ruler 5, the vertical upright bar 3 of reading ruler, crack width reading screw rod 6,7 and concrete foundation
Into the upright bar 3 vertical with reading ruler of reading ruler 5 is at right angles rigidly connected, and the plant consolidated by concrete foundation 2 is another in side slope crackle
In the stratum on one side, reading ruler 5 is parallel with side slope basal plane 1, and crackle reading mark screw rod 6,7 can be free to slide on reading ruler 5.
As shown in figure 3, it is the schematic diagram of specific embodiment of the present utility model, when the utility model is used, crack
One side set scale bar, another side set reading wand, and basis firmly be implanted into stratum in, graduated scale 4 is parallel with reading ruler 5
Alignment, spacing control is in the elongation range of crackle reading mark screw rod 6,7 and is not in contact with each other, and realizes and crack width is continued
Observation, comprises the following steps that description：
Step 1：The crack width reading screw rod 6,7 on reading wand is adjusted, is respectively aligned to the graduated scale 4 of scale bar, is read
