Description
Technical Field
The invention relates to the technical field of highway tunnels, in particular to a smoke discharge rescue system for a double-line tunnel and a construction method.
Background
When the automobile passes through the tunnel, the waste gas can be continuously discharged into the tunnel. When the tunnel is short, the waste gas is not high in concentration accumulated in the tunnel and drifts with the wind along with the time under the influence of natural wind and cross ventilation; when the tunnel is longer, waste gas can gather in the tunnel, and waste gas concentration reaches after the certain degree, will influence people's comfort level, reduces the visibility in the tunnel. Meanwhile, the motor vehicle may have fire and other accidents in the highway tunnel to discharge dense smoke, and the smoke in the tunnel has high concentration and needs to be discharged out of the tunnel as soon as possible. At present, the relevant specification of highway tunnels requires that the travel of smoke in the tunnels is not more than 5km, namely, a smoke exhaust system is required to be arranged for highway tunnels with the length of more than 5 km.
Fig. 1 and fig. 2 show prior art's system of discharging fume, right side tunnel through discharge fume cross tunnel and external intercommunication, left side tunnel through connect the wind channel with discharge fume the cross tunnel intercommunication, connect the wind channel and need go up to stride the right side tunnel and be connected with the cross tunnel of discharging fume, the flue gas in the left side tunnel loops through connecting the wind channel and discharges fume the cross tunnel and discharge fume. However, the connecting air duct is long in arrangement distance, so that the construction scale is large, the bending degree of the connecting air duct is large, and the smoke circulation is influenced; in addition, because the distance between the left line tunnel and the right line tunnel is small, and the common interval is 30m, the longitudinal slope of the connecting air duct is large, the slope can reach 40 degrees, and the construction difficulty is large; moreover, stride right side line tunnel on connecting the wind channel, its construction blasting vibrations are great to the right side line tunnel that the below has been under construction and has been accomplished, in order to avoid the vibrations influence, or control the blasting, or increase the interval of the two and increase the longitudinal gradient, and two kinds of modes all can increase the construction degree of difficulty.
The construction process of the traditional tunnel is as follows: the left tunnel and the right tunnel are constructed firstly, and the smoke exhaust system is constructed after the left tunnel and the right tunnel are constructed. It can be seen that the traditional construction method can only be used for one-way construction of a left tunnel and a right tunnel, which causes long construction period and high construction cost;
in the prior art, chinese patent CN206179212U is an automatic door opening system, which specifically includes: the steering engine is arranged beside a switch of the access control system and is connected with an Arduino board hardware part capable of sending a control signal; the infrared transmitter is connected with the infrared receiver through an infrared signal; the infrared receiver is connected with an Arduino board hardware part capable of receiving signals of the infrared receiver; the Arduino board, an open source electronic prototype platform, contains hardware and software. When a visitor wants to enter the access control system through the access control system, the person in the access control system only needs to press the button of the remote controller, the infrared receiver receives data and transmits the data into the processor of the Arduino board, and then the steering engine is controlled by the Arduino board to rotate to replace a hand to press the button. Traffic monitoring systems and fire monitoring systems are also relatively common and mature monitoring systems in the prior art.
