Background technology
Reinforcing rib meter is a kind of sensor measuring reinforcing bar and metal bar axially loaded, and can measure prison simultaneously as needed
The temperature value of measuring point is widely used in civil engineering, hydraulic and hydroelectric engineering and other engineering fields all the time.It is answering
When reinforcing the stress of anchor pole reinforcing bar with reinforcing rib meter monitoring works, reinforcing rib meter is first connected on anchor pole reinforcing bar, then again with anchor
Bar reinforcing bar is placed into side slope or landslide drilling, finally injects cement mortar into drilling again.Practice have shown that reinforcing rib meter monitors work
Journey anchor pole reinforcing steel bar bear, survival rate is undesirable, even zero when the collapse hole that drills (such as side slope or landslide rock mass are broken).Study carefully it
Reason, first, reinforcing rib meter with anchor pole reinforcing bar during being placed into drilling, reinforcing rib meter accesses the bending that cable is connect with it
Position is easy and borehole wall friction, leads to cable cuticular breakdown and induces the short circuit of cable inner core or open circuit；Second, anchor pole
The priming charge cement mortar water content that drills is high, is easy to cause moisture to infiltrating inside reinforcing rib meter, is unfavorable for its normal work；Its
Three, with the raising for pouring into strength of cement mortar, the exhibition that do not turn off in tunnel, side slope or Landslide Deformation causes anchor pole reinforcing steel bar bear
And it is axial to be easy to cause reinforcing rib meter cable since cement mortar tightly bonds reinforcing rib meter cable for the growth of cement mortar deformation
Stretching, and then induce the crack of cable epidermis split, be unfavorable for the long-term normal work of cable.But have not yet to see ground work
The journey monitoring device of high-survival rate reinforcing rib meter, this is problem urgently to be resolved hurrily！
Invention content
The shortcomings that the purpose of the utility model is to overcome the prior arts provides a kind of rock soil anchor monitoring reinforcing bar
Meter solves the problems, such as that existing ground monitoring reinforcing rib meter survival rate is low.
The utility model uses following technical scheme：
A kind of rock soil anchor monitoring reinforcing rib meter, including reinforcing rib meter main body and cable, the reinforcing rib meter main body are cased with guarantor outside

In addition, being provided with butter layer between cable protective sleeve and cable
Preferably, Acetabula device is filled with AB glue with the contact position of cable and reinforcing rib meter main body.
Preferably, it is provided with band outside cable protective sleeve.
Compared with prior art, the utility model has the following technical effects：
The reinforcing rib meter of the utility model, is not only avoided that injecting cement paste moisture to reinforcing rib meter internal structure potential for adverse effects,
Also it substantially increases during rockbolt installation to the protection of reinforcing rib meter cable and during rockbolt stress to reinforcing rib meter cable
Tunnel, side slope or landslide anchor pole monitoring reinforcing rib meter survival rate can be greatly improved, it is ensured that reinforcing rib meter engineering monitoring in potential protection
Durability, accuracy and validity.Meanwhile the reinforcing rib meter of the utility model, cheap, simple and practicable, economy is strong, mesh
It is preceding side slope, tunnel, foundation pit or landslide anchor pole monitoring etc. geotechnical engineerings field practice principle it is good.

Specific implementation mode
Embodiment 1：
Such as Fig. 1-3, the present embodiment provides a kind of rock soil anchor monitoring reinforcing rib meter, including reinforcing rib meter main body 1 and cable 2,
Protection pipe 3 is cased with outside reinforcing rib meter main body 1, length is equal to reinforcing rib meter length, and the tubing such as pvc pipe can be used, and cable 2 passes through protection pipe
3 connect with reinforcing rib meter main body 1, and cable 2 is provided with the Acetabula device 4 of tail portion opening, Acetabula device with 1 junction of reinforcing rib meter main body
4 are filled with AB glue 6 with the contact position of cable 2 and reinforcing rib meter main body 1.Bubble is filled between protection pipe 3 and reinforcing rib meter main body 1
Glue 5 is provided with AB glue 6 at 1 both ends of reinforcing rib meter main body and 3 contact position of protection pipe, fills thickness 0.5cm-1.0cm, not only ensure
Being connected and fixed between reinforcing rib meter protection pipe 3 and reinforcing rib meter, also prevents slip casting internal water and enters reinforcing rib meter cable 2 and steel
Potential abrasion of the rockbolt installation in the process to reinforcing rib meter cable 2 has also been reduced or remitted in the in-built joint of muscle meter.
