消火栓大家应该都知道，属于消防器材中的一种，日常生活中也比较常见，很多火灾都需要消火栓来灭火，所以其重要性不言而喻。但是消火栓系统在安装的过程中往往会出现一些常见通病，怎么去防治呢？
As we all know, fire hydrants are a kind of fire-fighting equipment, which is also common in daily life. Many fires need fire hydrants to put out the fire, so its importance is self-evident. But there are often some common problems in the installation of fire hydrant system. How to prevent them?
通病一：室外、屋顶采用暗装消火栓箱，箱体密封性差
Common problem 1: concealed fire hydrant boxes are used outdoors and on the roof, with poor sealing performance
产生原因及后果：一般暗装消火栓箱面板为铝合金，箱体采用冷轧铁皮（2InIn），刷红色面漆，不防水，长时间风吹日晒，箱体易腐蚀、生锈直损坏，箱内消防水带也易受潮腐烂。
Causes and consequences: generally, the panel of the concealed fire hydrant box is aluminum alloy, and the box is made of cold-rolled iron sheet (2inin), painted with red finish paint, which is not waterproof, and exposed to the wind and sun for a long time. The box is prone to corrosion, rust and damage, and the fire hose in the box is also prone to damp and rot.
防治措施及相关规定：使用明装式消火栓箱。
Prevention and control measures and relevant regulations: surface mounted fire hydrant box shall be used.
通病二：屋顶试验消火栓无压力表
Common problem 2: no pressure gauge for roof test hydrant
产生原因及后果：屋顶试验消火栓无压力表则不能直观反映消火栓系统高点的压力是否满足要求，于检修维护不便。
Causes and consequences: if there is no pressure gauge for the roof test hydrant, it cannot directly reflect whether the pressure at the high point of the hydrant system meets the requirements, which is inconvenient for maintenance.
防治措施及相关规定：屋顶试验消火栓安装压力表的目的是为了便于消防维护人员巡查时及时掌握消火栓系统压力是否满足消防要求，因此屋顶试验消火栓必须安装压力表（包括表弯及阀门）。
Prevention and control measures and relevant regulations: the purpose of installing a pressure gauge on the roof test hydrant is to facilitate the fire maintenance personnel to timely know whether the pressure of the hydrant system meets the fire protection requirements during patrol inspection. Therefore, the roof test hydrant must be installed with a pressure gauge (including a meter bend and a valve).
通病三：以沟槽连接方式安装的消火栓立管开分支管时，采用机械开孔三通
Common problem 3: when the branch pipe is opened for the fire hydrant riser installed by trench connection, the mechanical opening tee shall be used
产生原因及后果：在立管上采用机械开孔，其支管接头的构造属于马鞍形拼合式开孔套筒结构，其强度相对低于标准规格的沟槽式三通、四通等管件，有可能对立管强度产生影响。
Causes and consequences: mechanical opening is adopted on the riser, and the structure of its branch pipe joint belongs to saddle shaped split opening sleeve structure. Its strength is relatively lower than that of grooved tee, cross and other pipe fittings of standard specifications, which may have an impact on the strength of the riser.
防治措施及相关规定：《沟槽式连接管道工程技术规程》CECS151：2003规定“当立管上设置支管时，应采用标准规格的沟槽式三通、沟槽式四通等管件”，不得采用机械开孔安装机械三通的连接方式。
Prevention measures and relevant regulations: cecs151:2003, technical specification for grooved connection pipeline engineering, stipulates that "when branch pipes are set on the riser, grooved tee, grooved cross and other pipe fittings of standard specifications shall be used", and the connection method of mechanical tee installation through mechanical opening is not allowed.
通病四：沟槽连接的横管支吊架设置不当
Common problem 4: improper setting of horizontal pipe supports and hangers connected by grooves
产生原因及后果：由于沟槽式管件的结构（内有密封胶圈）特点以及沟槽滚沟质量，在管道水压及温度发生变化时，管道会产生一定的轴向力和位移，当其变化超过一定界限时，就有可能造成接口松脱或渗漏，在横管接头部位两侧设置支吊架的目的除支承管道重量外，主要是对管道轴向力和位移加以限制。
Causes and consequences: due to the structural characteristics of grooved pipe fittings (with sealing rubber rings inside) and the quality of groove rolling, when the water pressure and temperature of the pipeline change, the pipeline will produce a certain axial force and displacement. When the change exceeds a certain limit, it may cause the joint to loosen or leak. The purpose of setting supports and hangers on both sides of the horizontal pipe joint is not only to support the weight of the pipeline, It mainly limits the axial force and displacement of the pipeline.
川消防治措施及相关规定：《沟槽式连接管道工程技术规程》CEcs151：2003规定“横管吊架（托架）应设置在接头（刚性接头、挠性接头、支管接头）两侧和三通、四通、弯头、异径管等管件上下游连接接头的两侧。吊架（托架）与接头的净间距不宜小于150mm和大于300mm。
Prevention and control measures and relevant regulations of Chuanxiao: cecs151:2003 stipulates that "horizontal pipe hangers (brackets) should be set on both sides of joints (rigid joints, flexible joints, branch pipe joints) and on both sides of upstream and downstream connection joints of tee, cross, elbow, reducer and other pipe fittings. The clear distance between hangers (brackets) and joints should not be less than 150mm and more than 300mm.
