具体实施方式Detailed ways

下面结合附图并举实施例,对本实用新型进行详细描述。The utility model will be described in detail below in conjunction with the accompanying drawings and examples.

如图1和图2所示,在隧道邻近的山破上修建多条截排水沟,同一条截排水沟沿山坡的同一等高线修建,用于收集雨水在山上形成坡面流水;流水顺山势在截排水沟中流动。所有截排水沟的末端汇集至滤水池,滤水池修建在隧道附近的低洼处,截排水沟的水顺山势流入滤水池,滤水池通过管路与所述沉沙井接通;坡面流水中的泥沙在沉沙井沉淀后,清水从沉沙井井壁上部设置的管道自动流向低处的低位水池,再通过泵房将清水送至高位水池,由于高位水池的位置高于隧道消防栓的位置,消防栓中的水自动形成压力。高位水池的高度根据隧道消防栓的水压进行设置。为保证消防栓不间断供水,一组消防栓的进水管应不少于两条,当其中一条损坏时,其余的进水管仍能通过全部用水量。As shown in Figure 1 and Figure 2, multiple intercepting drainage ditches are built on the mountain break adjacent to the tunnel, and the same intercepting drainage ditch is built along the same contour line of the hillside to collect rainwater and form slope water on the mountain; the water flows along the mountain Potential to flow in the cut-off ditch. The ends of all intercepting drainage ditches are collected into the filter pool, and the filter pool is built in a low-lying place near the tunnel. After the sediment settles in the sand sinking well, the clean water will automatically flow from the pipes installed on the upper part of the sand sinking well to the low-level pool at the lower level, and then the clean water will be sent to the high-level pool through the pump room. Since the position of the high-level pool is higher than that of the tunnel fire hydrant , the water in the fire hydrant automatically builds up pressure. The height of the elevated pool is set according to the water pressure of the tunnel fire hydrant. In order to ensure the uninterrupted water supply of fire hydrants, there should be no less than two water inlet pipes for a group of fire hydrants. When one of the fire hydrants is damaged, the remaining water inlet pipes can still pass all the water.

压力传感器置于沉沙井的底部,压力传感器的输出端连接无线报警器;无线报警器设置在沉沙井的顶部,并通过无线方式与隧道消防系统的控制中心相连。通过设置压力传感器,对沉沙井中泥沙的多少进行检测,当泥沙过多时,向隧道消防系统的控制中心发送无线报警信号,提示工作人员对沉沙井的泥沙进行清理,避免沉沙井泥沙过多导致堵塞联通低位水池的管道,致使低位水池无法蓄水,造成隧道消防无水可用。The pressure sensor is placed at the bottom of the sand sinking well, and the output end of the pressure sensor is connected to a wireless alarm; the wireless alarm is set on the top of the sand sinking well, and is connected with the control center of the tunnel fire protection system by wireless. By setting the pressure sensor to detect the amount of sediment in the sedimentation well, when there is too much sediment, a wireless alarm signal will be sent to the control center of the tunnel fire protection system to remind the staff to clean up the sediment in the sedimentation well to avoid mud in the sedimentation well Excessive sand blocked the pipes connecting the lower pools, making it impossible to store water in the lower pools, resulting in no water available for firefighting in the tunnels.

为保证水量充足,所述低位水池与高位水池的容量相当,当高位水池的水用光后,低位水池可向高位水池补水一次,可保证在一次消防中向消防栓提供两个高位水池水量的用水。In order to ensure sufficient water volume, the capacity of the low-level pool and the high-level pool are equivalent. When the water in the high-level pool is used up, the low-level pool can replenish water to the high-level pool once, which can ensure that the water volume of the two high-level pools can be provided to the fire hydrant during a fire. use water.

为了不使进水管内积聚空气,高位水池与隧道消防栓之间的进水管向隧道消防栓方向上升的坡度,坡度为大于或者等于千分之五。In order to prevent air from accumulating in the water inlet pipe, the slope of the water inlet pipe between the high-level pool and the tunnel fire hydrant rising toward the tunnel fire hydrant shall be greater than or equal to 5/1000.

为保证高位水池的水能自动流入进水管中,高位水池与隧道消防栓之间连接的进水管在高位水池一端设置朝下的喇叭口,所述喇叭口低于高位水池的最低水位至少0.5米。喇叭口与高位水池池底的净距大于或等于0.8倍进水管管径,所述喇叭口边缘与高位水池池壁的净距大于或等于1.5倍进水管管径;所述两进水管之间的净距大于或等于3.5倍进水管管径。In order to ensure that the water in the high-level pool can automatically flow into the water inlet pipe, the water inlet pipe connected between the high-level pool and the tunnel fire hydrant is provided with a downward-facing bell mouth at one end of the high-level pool, and the bell mouth is at least 0.5 meters lower than the lowest water level of the high-level pool . The clear distance between the bell mouth and the bottom of the high-level pool is greater than or equal to 0.8 times the diameter of the water inlet pipe, and the clear distance between the edge of the bell mouth and the wall of the high-level pool is greater than or equal to 1.5 times the diameter of the water inlet pipe; the distance between the two water inlet pipes The net distance is greater than or equal to 3.5 times the diameter of the water inlet pipe.

寒冷山区的进水管须有防冻保护措施,因此高位水池与隧道消防栓之间连接的进水管外侧包扎有泡沫或防冻棉絮。The water inlet pipe in cold mountainous areas must have antifreeze protection measures, so the outside of the water inlet pipe connected between the high-level pool and the tunnel fire hydrant is wrapped with foam or antifreeze cotton wadding.

进水管应采取防腐措施,高位水池与隧道消防栓之间连接的进水管喷涂有除锈、除油或防酸的涂层。对于地下埋管,可以用沥青绝缘进行防腐处理。Anti-corrosion measures should be taken for the water inlet pipe, and the water inlet pipe connected between the high-level pool and the tunnel fire hydrant is sprayed with a rust-removing, oil-removing or acid-proof coating. For underground pipes, asphalt insulation can be used for anti-corrosion treatment.

如图3所示,截排水沟的截面呈倒梯形,所述截排水沟上表面的坡度为5%,用于排导坡面的地表积水。截排水沟每隔10至15米等距离开有伸缩缝,伸缩缝采用沥青麻布填充。As shown in FIG. 3 , the section of the intercepting drainage ditch is an inverted trapezoid, and the slope of the upper surface of the intercepting drainage ditch is 5%, which is used for draining surface water on the slope. Expansion joints are opened every 10 to 15 meters in the cut-off ditch, and the expansion joints are filled with asphalt sackcloth.

综上所述,以上仅为本实用新型的较佳实施例而已,并非用于限定本实用新型的保护范围。凡在本实用新型的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本实用新型的保护范围之内。In summary, the above are only preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
