室外地上式消火栓安裝時，消火栓頂距地面高為0.64m，立管應垂直、穩固、控制閥門井距消火栓不應超過2.5m，消火栓彎管底部應設支墩或支座。室外地下式消火栓應安裝在消火栓井內，消火栓井一般用MU7.5紅磚、M7.5水泥砂漿砌筑。消火栓井內徑不應小于1m。井內應設爬梯以方便閥門的維修。消火栓與主管連接的三通或彎頭下部位應帶底座，坻座時應設混凝土支墩，支墩與三通，彎頭底部用M7.5水泥砂漿抹成八字托座。擴展資料室外消火栓給水管道的布置應符合下列要求：
When installing outdoor aboveground fire hydrant, the height from the top of the fire hydrant to the ground is 0.64M, the riser shall be vertical and stable, the distance between the control valve well and the fire hydrant shall not exceed 2.5m, and buttress or support shall be set at the bottom of the fire hydrant elbow. The outdoor underground fire hydrant shall be installed in the fire hydrant well, which is generally MU7 5 red brick, M7 5. Cement mortar masonry. The inner diameter of fire hydrant well shall not be less than 1m. A ladder shall be set in the well to facilitate the maintenance of the valve. The lower part of the tee or elbow connecting the fire hydrant and the main pipe shall be equipped with a base. When the base is installed, a concrete buttress shall be set. The buttress and tee shall be connected, and the bottom of the elbow shall be M7 5 cement mortar shall be plastered into a splayed bracket. The layout of outdoor fire hydrant water supply pipeline shall meet the following requirements:
1.室外消火栓給水管道應根據室外消火栓設計用水量和管道的經濟流速經計算比較確定其管徑；
1. The diameter of the outdoor fire hydrant water supply pipeline shall be determined through calculation and comparison according to the design water consumption of the outdoor fire hydrant and the economic flow rate of the pipeline;
2．室外消防給水管網應布置成環狀管網，但在建設初期或室外消防用水量不超過20L/s時，可布置成枝狀管網；
2. The outdoor fire water supply pipe network shall be arranged as a ring pipe network, but it can be arranged as a branch pipe network at the initial stage of construction or when the outdoor fire water consumption does not exceed 20L / S;
3.消防給水管網應用閥門分成若干獨立段，每段內消火栓的數量不宜超過5個；
3. The fire water supply network shall be divided into several independent sections with valves, and the number of fire hydrants in each section shall not exceed 5;
4.室外消火栓給水管道應根據系統的供水量確定，且不應小于DN100。參考資料：百度百科-室外消火栓。
