Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As Fig. 1, Fig. 2, shown in Fig. 3 and Fig. 4, underground of the present utility model gate chamber air admission system, comprise flood discharging tunnel 1, Service gate room 2, air supply passage, described Service gate room 2 comprises room 3 and lower room 4, described flood discharging tunnel 1 is communicated with Service gate room 2, described air supply passage one end is for entering hole 5, the other end is communicated with Service gate room 2, described flood discharging tunnel 1 is two or more, and the axis of flood discharging tunnel 1 is parallel to each other, described air supply passage comprises the main hole of ventilation and a ventilation hole 6, described ventilation is propped up hole 6 and is arranged on 2 times rooms 4, Service gate room place, described ventilation is propped up hole 6 and is drawn from ventilation Zhu Dongzhong branch, each root ventilation hole 6 is communicated with a flood discharging tunnel 1.Adopt the form of structure that the main hole of ventilation combines with a ventilation hole 6, in Service gate room, 2 times rooms 4 place arranges the ventilation be connected with each flood discharging tunnel 1 and props up hole 6, and a ventilation hole 6 enters into underground to a certain degree by the main hole of ventilation, draw again after the flood discharging tunnel 1 be arranged in parallel, multiple like this flood discharging tunnel 1 just can share a main hole of ventilation by a ventilation hole 6, and do not need to build multiple independent ventilation system comprising complete structure, greatly reduce the construction of underground passage, save construction period construction cost time, avoid the transition excavation at the end over the ground, avoid the impact on underground structural stability.
The main hole of described ventilation comprises introduces section 7 and vertical section 8, and described introducing section 7 will be entered hole 5 and be communicated with vertical end, and described ventilation is propped up hole 6 and is communicated with vertical section 8, and described vertical section 8 is arranged along the direction vertical with flood discharging tunnel 1 axis.Be divided in main for ventilation hole and introduce section 7 and vertical section 8, vertical section 8 is vertical with flood discharging tunnel 1 puts the length that can shorten main hole of ventilating, and reduces construction works amount.Adjustment trend is started in introducing section 7 in the position near first flood discharging tunnel 1 during concrete enforcement, ventilate after the one section of channel transition direction in main hole is adjusted to and subvertical direction, flood discharging tunnel 1 axis, changeover portion steadily, not easily sharply changes the trend of passage as far as possible.
Also comprise lower curved section 9, described lower curved section 9 one end is communicated with vertical section 8, and the other end is communicated with a ventilation hole 6.Lower curved section 9 is used for that vertical section 8 is propped up hole 6 with the ventilation being arranged on 2 times rooms 4, Service gate room and is communicated with, and because lower curved section 9 and vertical section 8 junction are higher than itself and a ventilation junction, hole 6, therefore lower curved section 9 is in downward-sloping trend.
The trend of the utility model gas is: first from entering the vertical section 8 of hole 5 by the main hole of introducing section 7 arrival ventilation in the main hole of ventilation, then through from vertical section 8 and arrival lower curved section 9, be diverted to each ventilation hole 6 from lower curved section 9, finally enter into corresponding flood discharging tunnel 1 by each ventilation hole 6.So just achieve the function utilizing an aerating system to ventilate to multiple flood discharging tunnel 1.
