Description
Technical field
The invention belongs to Tunnel Blasting gas dust detection device technical field, major long tunnel is can be used in more particularly, to one kind
Artificial observation is needed not rely in engineering explosion work progress and does qualitative analysis, just can be quickly to being slapped after Tunnel Engineering blast working
The air quality of the sub- a range of construction operation environment in face and the security of construction are judged, comprehensive quantification monitoring
Face neighbouring different distance, different height, the gas dirt monitoring device of different time after Tunnel Blasting construction.
Background technology
Existing major long tunnel is mainly composite explosives with explosive, and composition is mainly nitro compound, nitramine (ammonium) chemical combination
Thing and various carbon compounds, its explosion time can generate CO, NO, NO2Deng toxic and harmful gas, and existing long tunnel
During blast working, often using this composite explosives, while by length of tunnel length (being more than 3Km), excavated section area
(it is more than 50m greatly2) etc. factor influence, also produce substantial amounts of dust in addition to substantial amounts of toxic and harmful gas is generated.
Existing long tunnel is in work progress, for these problems occurred, and the main method of use is to apply
Only with artificial empirically determined to a range of ventilation time and vent flow near face during work, but for tunnel
The toxic and harmful gas and the concentration of dust that face is nearby remained after ventilation certain time after road explosion but lack necessary
Quantification reference data, if on-site personnel manipulation ventilation time in tunnel is lacked experience, makes near input tunnel tunnel face
A range of ventilation is less, may result in tunnel on-site personnel poisoning or suffers from pneumoconiosis, endangers field operation people
The health of member and personal safety, but if on-site personnel manipulation ventilation time in tunnel is longer, when not only wasting constructing tunnel
Between reforwarding quarrel node behind influence tunnel, but also the driving speed of whole Tunnel Engineering can be influenceed, also result in energy resource
Waste, the cost of whole Tunnel Engineering can be increased.
A kind of tunnel tunnel face ventilated control systems of the A of Chinese patent CN 103835743, including it is laid in constructed tunnel
Control device at road face, the tunnel ventilation device being laid in institute's construction tunnel, to institute's construction tunnel face at
Air Quality monitoring device that Air Quality is detected and the oxygen processed being laid at institute's construction tunnel face
Equipment and liquid dust removing spraying apparatus.The method is mainly to provide a kind of tunnel tunnel face ventilated control system, the purpose is to
Carry out Optimal regulation and control to the environmental aspect at face, but cannot be used in Tunnel Blasting construction face nearby it is different away from
From, the real-time monitoring under different height, different time in the case of the multiple gases such as CO, NO and dust symbiosis, while can not be right
A range of vent flow is measured near input tunnel tunnel face, it is impossible to which the real time temperature near tunnel tunnel face is entered
Row is measured, it is impossible to which a range of construction safety environment is judged near the face after the quick construction to Tunnel Blasting.
The A vcehicular tunnels flue dust of Chinese patent CN 103278435 is detected and ventilation unit, is characterized mainly in that in tunnel
Multiple spot installs photoelectric sensor, in addition to bandwidth-limited circuit, amplifying circuit, A/D converter circuit and the single-chip microcomputer being sequentially connected,
Single-chip microcomputer is connected with controlled motor output circuit, sound light alarming circuit and early warning display circuit respectively again.The method is only used for inspection
Survey vcehicular tunnel in dust concentration, and when in vcehicular tunnel dust concentration it is exceeded and influence driver and conductor drive a vehicle sight when,
Ventilating system is opened in time, driver's Reduced Speed Now is reminded by audible-visual annunciator, and the vigilance for improving driving personnel is reached with this
Property, reduce the purpose that traffic accident occurs, but the method cannot be used for CO, NO and dust during major long tunnel blast working
Monitoring, it is impossible to after rapid measuring Tunnel Blasting near face a range of vent flow and construction operation environment it is suitable
Temperature.
