Embodiment 1

[0022] The invention discloses a method for opening a fire shutter of an urban underground communication passage. Firewalls and fire shutters are used to separate the urban underground communication passage from the underground garage. When a fire breaks out, such as figure 1 As shown in , the urban underground connection channel is regarded as a circular channel independent of the underground garage. The traffic organization mode is mainly one-way clockwise, and fans 5 are uniformly arranged in the annular passage.

[0023] Such as figure 1 As shown, the annular passage is provided with a first outlet, a first shaft 6 , a second inlet, a second outlet and a second shaft 11 sequentially clockwise from the first inlet. The first fire shutter 1 and the second fire shutter 2 are correspondingly provided on both sides of the first entrance, and the third fire shutter 3 and the fourth fire shutter 4 are correspondingly provided on both sides of the first exit. The fifth ...

Embodiment 2

[0028] The invention discloses a method for opening a fire shutter of an urban underground communication passage. Except the opening method of fire shutter, all the other are with embodiment 1.

[0029] When a fire breaks out in the second smoke control area, start the third fire shutter 3 first, and use the first smoke control area and the second smoke control area as the second smoke control unit; then open the second smoke control area. All fans 5 in the whole are controlled, fresh air enters from the first outlet, and smoke is discharged from the first shaft 6 .

Embodiment 3

[0031] The invention discloses a method for opening a fire shutter of an urban underground communication passage. Except the opening method of fire shutter, all the other are with embodiment 1.

[0032] When a fire breaks out in the third smoke control area, start the sixth fire shutter 8 first, and use the third smoke control area and the fourth smoke control area as the third smoke control unit; then open the third smoke control area. All fans 5 in the whole are controlled, the fresh air enters from the first shaft 6, and the flue gas is discharged from the second inlet.

Abstract

The invention relates to an opening method of urban underground contact channel fire resisting shutters. The opening method is characterized in that an urban underground contact channel is regarded as an annular channel independent from an underground garage; the annular channel is provided with two inlets, two outlets, a first vertical shaft (6), a second vertical shaft (11) and multiple fans (5); and fire resisting shutters are correspondingly arranged at the two sides of each outlet or inlet. According to the layout of the vertical shafts and the inlets and outlets, the annular channel is divided into eight smoke control areas by using the fire resisting shutters. When fire occurs, the corresponding fire resisting shutters are opened firstly, and the smoke control area with the fire and the adjacent smoke control areas serve as a smoke control integer; and then, all the fans (5) in the smoke control integer are opened, so that smoke is discharged to the ground in a set smoke discharge area in a vehicle driving direction. The opening method can effectively solve the problem of irregular smoke spreading of the fire, and can guarantee the escape safety of vehicles and persons.

Description

technical field [0001] The invention belongs to the technical field of fire protection of urban underground communication passages. In particular, the invention relates to a method for opening a fire shutter of an urban underground communication passage. Background technique [0002] The urban underground connection channel is a new form of underground transportation, which is specially used to connect the underground garage with the road on the ground. Most of the combustibles in urban underground communication passages are gasoline and diesel oil, etc. Once a fire occurs in urban underground communication passages, the high temperature and toxic smoke generated will spread around irregularly and it is extremely difficult to discharge in time, which will damage some underground spaces. Facilities and personnel will cause great harm and easily cause serious accidents. At present, there are few researches on fire smoke control methods of urban underground communication pas...
