If having obtained significant progress.In this process, tunnel is widely applied as a kind of effective means crossed over mountain after mountain.
But since China has a vast territory, environment is complicated, and some toxic and harmful gas, such as methane, hydrogen sulfide are contained in many stratum.
Geologic prospect technology can't accurately predict the preservation situation of toxic and harmful gas at present.Thus tunnel was being constructed
It can be potentially encountered toxic and harmful gas evolution in journey or dash forward and gush, it is sluggish in air circulation since tunnel is a hemi-closure space,
If toxic and harmful gas, which cannot be discharged in time outside hole, to be gathered in face position, construction personnel can be not only good for
Health has an important influence on, it is also possible to have the danger of explosion.Due to the influence of the factors such as blasting impact and dust frequent in tunnel,
Traditional sensor-based measuring instrument is difficult to carry out real-time measurement under adverse circumstances in tunnel.
At present for being typically all to use man-hour manually hand-held formula toxic and harmful gas there are the tunnel of toxic and harmful gas risk
Measuring instrument measures, and informs that in-cavity construction personnel remove if measurement result shows toxic and harmful gas excessive concentration
From in other words, which relies primarily on manual operation, artificial detection, manual record, artificial early warning, which has certain
Hysteresis quality, while the precision and order of accuarcy measured is heavily dependent on the influence of operator subjective factor itself, no
It accurately and timely can objectively reflect the preservation situation of toxic and harmful gas in hole.This also increases the risks of constructing tunnel, cause
The generations of many construction accidents.
Existing monitoring device protective device is weaker simultaneously, and the ability for resisting external environment detrimental impact is weaker such as existing
Equipment is difficult to resist the impact of the disasters such as landslide, explosion and floods.Once disaster occurs in tunnel, then monitoring instrument just will receive
It is serious to destroy, the offers support such as subsequent analysis on accident cause is provided.
