Description

A kind of tunnel geological forecast electric detonator initiation controls device

Technical field

This utility model belongs to geologic prediction signal to be triggered and detonator excitation technique field, is specifically related to a kind of tunnel advanced Geologic prediction electric detonator initiation controls device.

Background technology

Grasp tunnel front geological condition, have highly important effect for tunnel construction.By advanced prediction, in time Unusual circumstance, the integrity of the forecast position of front of tunnel heading unfavorable geologic body, occurrence and surrounding rock structure thereof is with aqueous Probability, for correctly selecting excavated section, support parameters and Optimizing Construction Scheme to provide foundation, and gushes for prevention tunnel The disastrous accident that water, prominent mud, prominent gas etc. are likely to be formed provides information in time, makes engineering unit carry out preparation of construction in advance, protects Card construction safety, the most also can save substantial contribution.

TGP tunnel geological forecast seismic wave method is outside in arrange on the same level line of tunnel one side wall One receptor (another receptor is laid in the position that the same side is identical) and 24 big gun holes, exciting detonator detonating charge While trigger TGP geologic prediction instrument, the seismic wave excited in utilizing big gun hole to three dimensions propagate during, run into sound Impedance interface, both interface, structurally fractured zone, karst and the karst growth zone etc. of geologic lithology change, it may occur that elastic reflection Phenomenon, the detector arrangement that this echo is disposed in tunnel surrounding receives, be input in instrument to carry out signal amplification, Digital collection and process, it is achieved the reflected wave information in pickup front of tunnel heading rock mass, reach the purpose of forecast.

At present, TGP tunnel geological forecast signal triggers and excites respectively by triggering bus and exciting bus even with detonator Connect control, before each track data collection, all need workman to connect firing line the most respectively, trigger bus and excitation line, detonator line, this One method has time-consuming long, unsafe shortcoming.The method that the Cui Yi peace opponent of Central South University is dynamically connected is improved, permissible After once connecting porous focus, the most automatically excite the focus that detonates, though the collection data that this method can be efficient, safe, but nothing Waveform is diagnosed in gatherer process and takes corrective measure by method；Secondly, this device only excites bus, and does not trigger Bus, is only applicable to TSP advance geologic prediction instrument；Again, it is integrated that the environment that newly built tunnels is moist, shake the most seriously constrains band The application of this device of circuit board.To sum up stating, manual method of attachment poor efficiency, dangerous, automatic connection method is owed flexibly, no Stablize and be not suitable for TGP geologic prediction instrument.

Summary of the invention

This utility model purpose is to provide a kind of tunnel geological forecast electric detonator initiation to control device, overcomes manually Method of attachment poor efficiency, dangerous, automatic connection method owes the shortcoming of flexible, unstable and inapplicable TGP geologic prediction instrument, this dress Put and do not use any circuit board and welding procedure, adapt to moist in newly built tunnels, the environment of vibrations and to be applicable to TGP geology pre- Report instrument.
