Description
Technical Field
The invention relates to the technical field of environment monitoring, in particular to a tunnel construction environment monitoring method.
Background
Along with the improvement of the linear standard of the road design and the increase of the number of construction mileage, the number of road tunnels, particularly mountain highway tunnels, is increased. Meanwhile, in the years, the tunnel is developed towards the direction of longer and longer length, larger and larger section and more complex geological conditions. However, such a trend has led to tunnels facing greater and greater environmental problems during construction. In the tunnel construction, due to geological reasons, toxic and harmful gases can be generated, for example, in the process that the tunnel penetrates through a coal-containing stratum, gas can be met, some stratums can be enriched with hydrogen sulfide and the like, and the toxic and harmful gases are released to a construction area along with the excavation of the tunnel. During construction, incomplete combustion of the engine fuel of the working machine also generates a large amount of toxic and harmful gases, such as CO and nitrogen oxides. In tunnels constructed by the drilling and blasting method, a large amount of substances such as CO, nitrogen oxides and dust are also generated due to the explosion of explosives. When the slurry spraying operation is carried out in the tunnel, a large amount of dust is also generated. These threaten the physical and psychological health of workers and the safety of tunnel construction.
At present, in the construction of a high gas tunnel, a safety monitoring system is generally installed, the system mainly monitors the gas concentration in the tunnel through various gas sensors installed at different parts of the tunnel, and data of each sensor is displayed in a monitoring room at a tunnel portal. However, the sensors of the existing monitoring system are generally only installed in key places such as a tunnel face, a cross tunnel fork, a cave entrance and the like, so that the concentration conditions of pollutants in the key places can only be monitored; however, pollutants can be continuously diffused in the tunnel, and the concentration distribution condition of the pollutants in the whole tunnel cannot be accurately mastered only by monitoring a plurality of key points, so that managers cannot make strategies more reasonably, and the harm of environmental pollution to the health of workers is avoided.
Disclosure of Invention
In view of this, the present invention provides a method for monitoring a tunnel construction environment, so as to solve the technical problem that a tunnel environment safety monitoring system can only detect the pollutant concentration at some key locations in a tunnel, but cannot monitor the pollutant concentration in any area in the tunnel.
The invention relates to a tunnel construction environment monitoring method, which comprises the following steps:
1) arranging sensors for measuring the concentration of pollutants in the tunnel environment at regular intervals in the tunnel;
2) establishing a tunnel model in fluent software configured by a monitoring host, simulating cloud pictures of monitored pollutants distributed in the tunnel model under various different set concentrations by utilizing the fluent software, extracting concentration data of points in the cloud pictures corresponding to the positions of the sensors arranged in the tunnel, and storing all the obtained cloud pictures and the concentration data of all the points extracted from the cloud pictures into a database;
3) the monitoring host reads the detection data of the sensor once every other set detection period, searches the distribution cloud picture of the corresponding pollutant in the database according to the detection data of the sensor, takes the cloud picture as the real distribution cloud picture of the pollutant in the tunnel at the moment when the concentration data of each point extracted from a certain cloud picture is the same as the detection data of the corresponding sensor, and displays the cloud picture and the detection data of the sensor through the display.
The invention has the beneficial effects that:
according to the tunnel construction environment monitoring method, the cloud image database in which pollutants are distributed in the tunnel is established, the corresponding cloud images are searched from the cloud image database according to the real detection data of the sensor, and managers can know the pollutant concentration conditions of different positions in the whole tunnel area through the searched corresponding cloud images, so that the managers can reasonably make strategies, and the harm of environmental pollution to the health of workers is avoided.
