Summary of the invention
The object of the present invention is to provide a kind of measurement efficiency is high, the measurement scope of activities is large, simple to operate, easy to maintenance, accuracy of observation is high, economical and practical slope crack monitoring device and measuring method thereof.
The technical solution that realizes the object of the invention is:
A kind of slope crack monitoring device, comprise spud pile, set collar and convergence gauge, wherein, spud pile is arranged on the both sides in crack, and set collar is fixedly connected with spud pile, the hook of convergence gauge steel ruler one end and the set collar of a side articulate, and the hook of convergence gauge instrument one end and the set collar of opposite side articulate.
A kind of slope crack monitoring method comprises the following steps:
Step 1: the both sides in crack arrange spud pile;
Step 2: top or a side at spud pile are fixedly connected with set collar;
Step 3: the hook of convergence gauge steel ruler one end is articulated on the set collar of a side, the hook of convergence gauge instrument one end is articulated on the set collar of opposite side, utilize steel ruler spool handle to eliminate the steel ruler sagging, and make register pin pass punching nearest on steel ruler.
Step 4: rotate the steel ruler rocking handle, the pulling force on steel ruler is adjusted to while meeting the demands, and can on digital display centimeter, read reading.
The present invention compared with prior art, its remarkable advantage:
(1) the present invention adopts convergence gauge to measure the Fracture Deformation situation, can select the convergence gauge of suitable accuracy to be measured operation according to requirement of engineering, and convergence gauge can continue to use after engineering finishes.
(2) the present invention installs simply, easy to operate, but Reusability is economical and practical, and measuring principle is simple, and measuring accuracy is high, and antijamming capability is strong, stable and reliable for performance.
Below in conjunction with accompanying drawing, the present invention is described in further detail.
The accompanying drawing explanation
Fig. 1 is the schematic diagram of invention structure.
