Description
Technical field
The present invention relates to a kind of automation loading device for the geologic prediction instrument being used in construction tunnel, more particularly to one
Plant the loading device and method of TBM seismic wave advanced prediction instruments.
Background technology
With continuing to develop for tunnel construction, TBM is due to " driving speed is fast, and cavitation quality is high, high financial profit "
The advantages of, obtain increasing application.But TBM is poor to the adaptability of geological conditions, under complex geological condition, often
The unfavorable geology factor such as tomography, crushed zone, solution cavity is run into, the TBM card machines even major accident such as fatal crass is easily caused.Therefore,
The geological conditions for verifying Tunnel Passing location is particularly important, if can know whether driving front has tomography, crushed zone, solution cavity in advance
Deng harm geological structure, then arrangement and method for construction can be adjusted in time, safeguard procedures are arranged, it is to avoid dangerous situation occurs.
Different from the tunnel of drill bursting construction, TBM construction tunnels are due to complicated metal structure, and observation space ten
It is point narrow and small, therefore traditional electromagnetic method such as conventional geological radar method and transient electromagnetic method receives serious limitation, Effect on Detecting
It is not satisfactory.However, seismic wave method be disturbed in TBM construction tunnels it is small, and to lithology interface (tomography, solution cavity etc.) sensitiveness
Height, has advantage in terms of front of tunnel heading unfavorable geologic body is known.In seismic wave method detection, the installation of focal point and wave detector
Largely determine the interpretation result degree of accuracy of detection data.Consider TBM a rate of advance fast, geology detecting when
Between it is shorter, it is a kind of while gathered data quality is ensured to need proposition badly, can quickly and easily complete observation system arrangement
Loading device.
At present, earthquake advanced prediction instrument mainly uses and manually installs vibration exciter and wave detector, efficiency in TBM tunnels
Lowly；The method for loading of existing observation system mainly has following several：The patent of domestic relevant scholar's application《In rock tunnel(ling) machine
Active source 3-D seismics advance geology exploration device and method》(application number：201510106173.6) pacify focus and wave detector
On hydraulically extensible bar, realize it is automatic carry and couple, but focus and wave detector position tunnel axis direction relative to
TBM is fixed, fails to realize flexibly impulsing for axis direction；Patent《Tunnel dimensionally seismic wave forward probe spatial observation system
System and method》(application number：201610411224.0) using telescopic spring hammer explosive source, it is necessary to which artificial fill energy, utilization
Bond and bolt fixes two methods and installs fixed block, be required to manually be pasted or torquing operations, although big compared to traditional
Hammer impulses and has had progress, but automatization level is still waited to improve.In summary, it is primarily present problems with：
(1) wave detector installation effectiveness is low：The installation of wave detector needs to be transmitted the company of optical fiber, fixed block and wave detector etc.
Connect and the coupling with wall, existing common method bores aperture using impact drill on wall, fixed block passes through metal bar and anchor
Gu agent is fixed, this method wastes time and energy, it is also possible to and can be because tunnel wall be flooded profit and influences coupling effect, it is impossible to
To preferable detection data, site operation is influenceed, therefore need a kind of installation effectiveness height, the good automation wave detector of coupling effect badly
Mounting means；
(2) reusability of acquisition system is poor：In current tunnel detection method, the disassembly ＆ recycling step of acquisition system is answered
Miscellaneous, the fixed block by long-time bonding is difficult to remove, and cleaning Anchor Agent is time-consuming longer, thus need a kind of fast and easy badly can
The wave detector mounting means of repeatability handling；
(3) arrangement of focus is dumb：In TBM tunnels, because development machine occupies the tunnel space of the overwhelming majority, because
This does not possess the condition for installing large automatic equipment, and existing small automatic installs equipment when installing focus, perpendicular
Nogata to fitting limit it is limited.Need badly propose it is a kind of can automatically multiple spot hammer focus loading device；
(4) the observation system arrangement time is longer：Artificial arrangement observation system is time-consuming longer, and some patents are directed to focus and inspection
The automation of ripple device has been disposed with a certain degree of improvement, but because TBM processes are compact, a rate of advance is fast, its automatization level
Still need to further raising.
