Abstract
A kind of tunnel machine excavates weak surrounding rock mutation prior-warning device and is related to a kind of device for being mutated early warning to weak surrounding rock during tunnel machine excavation construction.Mainly solve at present to deform tunnel weak surrounding rock and supporting construction is monitored the problem of pre-warning time is long and designs.Two fixing bolts are installed in vault, a fixing bolt is respectively filled at two haunches, laser reflection tablet is loaded on the fixing bolt at two haunches, it is located in vault on anterior fixing bolt and loads onto laser reflection tablet, laser transmitting-receiving inductor is installed at vault, three laser beam emitting heads on laser transmitting-receiving inductor are respectively aligned to vault, the laser reflection tablet center at haunch, data wire on laser transmitting-receiving inductor is connected with tunnel intraoral illumination power line, and inductor early warning loudspeaker is connected in the junction.Advantage is to provide safe early warning to scene in time.
Description
Technical field：
The utility model is related to a kind of device for being mutated early warning to weak surrounding rock during tunnel machine excavation construction.
Background technology：
During tunnel machine excavation construction, according to many changes of geological condition, can run into greatly it is uncertain because
Element, generally construction in tunnel weak surrounding rock deformation and supporting construction be monitored early warning when, be by manual work mode,
It the measuring apparatus such as spirit level, total powerstation taken, will be analyzed after data acquisition, this process is very long, but tunnel
Weak surrounding rock, which caves in, to be occurred to occur in the short period of time, and the country rock mutation in tunnel can be produced to in-cavity construction personal security
It is serious to threaten.
The content of the invention：
Technical problem to be solved in the utility model is to provide a kind of tunnel machine and excavates weak surrounding rock mutation early warning dress
Put, which solving can not the problem of early warning in time after being mutated because of tunnel machine excavation weak surrounding rock.
What above-mentioned purpose was realized in：It includes front and rear two fixations excavated installed in tunnel machine on country rock vault
Bolt, described the two fixing bolts will be on same straight line, in addition to the fixing bolt at two haunches,
Lower laser reflection tablet is respectively mounted on fixing bolt at two haunches, is located in vault on anterior fixing bolt and installs
Upper laser reflection tablet, installs on another fixing bolt at the vault apart from upper laser reflection tablet 10-20m and swashs
Three laser beam emitting heads that light is received and dispatched on inductor, laser transmitting-receiving inductor are respectively aligned to the upper laser reflection tablet on vault
With the center of two lower laser reflection tablets at haunch, the data wire on laser transmitting-receiving inductor is connected with power line,
The junction connection inductor early warning loudspeaker, i.e. inductor early warning loudspeaker are connected with data wire and power line, when weakness is enclosed
After petrosal process becomes, the laser signal of laser transmitting-receiving inductor irradiation departs from after reflection tablet, signal can be passed into sensing immediately
Device early warning loudspeaker sends alarm, and safe early warning effect is provided to scene.
The utility model has the advantages that：After weak surrounding rock is mutated, the laser signal of laser transmitting-receiving inductor irradiation departs from
Reflect after tablet, signal can be passed into inductor early warning loudspeaker immediately and send alarm, safe early warning is provided to scene
Effect, makes workmen receive warning information.Its warning information is accurate, and method is simple.
Brief description of the drawings：
It in structural representation of the present utility model, figure 7 is vault that Fig. 1, which is, and 8 be haunch.
Embodiment：
Reference picture 1, it includes front and rear two fixing bolts excavated installed in tunnel machine on country rock vault, described this
Two fixing bolts will be on same straight line, in addition to the fixing bolt at two haunches, at two haunches
Lower laser reflection tablet 1 is respectively mounted on fixing bolt, is located in vault on anterior fixing bolt and installs laser reflection
Tablet 2, installs laser transmitting-receiving sense on another fixing bolt at the vault apart from upper laser reflection tablet 10-20m
Three laser beam emitting heads on device 3, laser transmitting-receiving inductor are answered to be respectively aligned to upper laser reflection tablet and haunch on vault
Data wire 4 on the center of two lower laser reflection tablets at place, laser transmitting-receiving inductor is connected with power line 5, in the company
Place's connection inductor early warning loudspeaker 6 is connect, i.e. inductor early warning loudspeaker is connected with data wire and power line, when weak surrounding rock is prominent
After change, the laser signal of laser transmitting-receiving inductor irradiation departs from after reflection tablet, signal can be passed into inductor immediately pre-
Alert loudspeaker sends alarm, and safe early warning effect is provided to scene.
