Abstract
The invention relates to a device used for conducting sudden-change early-warning on weak surrounding rock in the tunnel machine excavating construction process, in particular to a sudden-change early-warning device for weak surrounding rock excavating through a tunnel machine. The sudden-change early-warning device is designed mainly for solving the problem that currently, the monitoring and early-warning time for tunnel weak surrounding rock deformation and support structures is long. Two fixing bolts are mounted on a vault, two haunches are each provided with a fixing bolt, lower laser reflecting sensing plates are mounted on the fixing bolts at the haunches, and an upper laser reflecting sensing plate is mounted on the front fixing bolt at the vault. A laser receiving and sending sensor is mounted at the vault, three laser emitting heads of the laser receiving and sending sensor are aligned with the centers of the laser reflecting sensing plates at the vault and the haunches correspondingly, a data line on the laser receiving and sending sensor is connected with a lighting power line in a tunnel, and a sensor early-warning loudspeaker is connected to the joint of the data line and the lighting power line. The sudden-change early-warning device has the advantage that safety early-warning is provided for a site in time.
Description
Technical field：
The present invention relates to a kind of device for being mutated early warning during tunnel machine excavation construction to weak surrounding rock.
Background technology：
During for tunnel machine excavation construction, according to many changes of geological condition, great uncertain factor can be run into, be led to
In often constructing when deforming to tunnel weak surrounding rock and supporting construction is monitored early warning, it is, by manual work mode, to take
The measuring apparatus such as spirit level, total powerstation, will be analyzed after data acquisition, and this process is very long, but the weakness in tunnel
Wall damage occurs to occur in the short period of time, and the country rock mutation in tunnel can produce serious to in-cavity construction personal security
Threaten.
The content of the invention：
The technical problem to be solved is to provide a kind of tunnel machine and excavates weak surrounding rock mutation prior-warning device, its solution
Because tunnel machine is excavated can not the problem of early warning in time after weak surrounding rock mutation.
What above-mentioned purpose was realized in：First, the vault for excavating country rock in tunnel machine is installed former and later two and fixes spiral shell
Bolt, the two described fixing bolt will respectively install a fixing bolt, after just propping up at two haunches on same straight line
Lower laser reflection tablet is respectively mounted on the fixing bolt at two haunches, is located on anterior fixing bolt in vault and is pacified
Laser reflection tablet is loaded onto, is pacified on second fixing bolt at the vault apart from vault laser reflection tablet 10-20m
Dress laser transmitting-receiving inductor, ensures during installation that balance is firm, and three on laser transmitting-receiving inductor laser beam emitting head is respectively aligned to
Laser reflection tablet center at vault, haunch, the data wire on laser transmitting-receiving inductor are connected with tunnel intraoral illumination power line
Connect, be connected with data wire and mains lighting supply line in junction connection inductor early warning loudspeaker, i.e. the inductor early warning loudspeaker,
After weak surrounding rock is mutated, after the laser signal of laser transmitting-receiving inductor irradiation departs from reflection tablet, immediately signal can be passed
Pass inductor early warning loudspeaker and send alarm, act on there is provided safe early warning to scene.
It is an advantage of the invention that：After weak surrounding rock is mutated, the laser signal of laser transmitting-receiving inductor irradiation departs from reflection
After tablet, signal transmission can be sent into alarm to inductor early warning loudspeaker immediately, be acted on there is provided safe early warning to scene,
Workmen is made to receive early warning information.Accurately, method is simple for its early warning information.
Description of the drawings：
Fig. 1 is the installment state schematic diagram of the present invention.
Specific embodiment：
With reference to Fig. 1, first, the vault 7 for excavating country rock in tunnel machine installs former and later two fixing bolts, and the two described are solid
Determine bolt and a fixing bolt will be respectively installed after just propping up on same straight line at two haunches 8, consolidating at two haunches
Determine on bolt, to be respectively mounted lower laser reflection tablet 1, be located on anterior fixing bolt in vault and install laser reflection sense
Plate 2 is answered, laser transmitting-receiving sense is installed on second fixing bolt at the vault apart from vault laser reflection tablet 10-20m
Device 3 is answered, during installation, ensures that balance is firm, three on laser transmitting-receiving inductor laser beam emitting head is respectively aligned at vault, haunch
Laser reflection tablet center, the data wire 4 on laser transmitting-receiving inductor is connected with tunnel intraoral illumination 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 mains lighting supply line, when weakness is enclosed
After petrosal process becomes, after the laser signal of laser transmitting-receiving inductor irradiation departs from reflection tablet, can be immediately by signal transmission to sensing
Device early warning loudspeaker sends alarm, acts on there is provided safe early warning to scene.
