天沟外排水系统
Outer drainage system
天沟外排水即利用屋面构造上所形成的天沟本身容量和坡度,使雨雪水向建筑物两端(山墙、女儿墙方向)泄放,并经墙外立管排至地面或雨水管道。由天沟、雨水斗、排水立管和排出管组成。适用于长度不超过100m的多跨工业厂房,以及房内不允许布置雨水管道的建筑。
The outer drainage of the roof is to use the capacity and slope of the roof of the roof, so that the rain and snow water is discharged to the two ends of the building (the direction of the parapet and the parapet), and through the wall outside the wall to the ground or the rainwater pipe. The utility model is composed of a gutter, a rain bucket, a drainage riser and an exhaust pipe. It is suitable for multi span industrial buildings with a length of not more than 100m, and a building with no rainwater pipes in the room.
在工程实践中常采用天沟外排水的方式排除大型屋面的雨雪水,采用天沟外排水不仅能消除厨房内部检查井冒水的问题,而且具有节约投资、节省金属材料、施工简便,利于合理地使用厂房空间和地面以及为厂区雨水系统提供明沟排水或减少管道埋深等优点;但若设计不善或施工质量不良,会出现天沟翻水、漏水等问题。
In the engineering practice, the rain and snow water of large roofs is often eliminated in the way of draining the large roof, and the use of the outer drain can not only eliminate the problem of checking the water in the well inside the kitchen, but also saves the investment, saves the metal material and the construction is simple, and is beneficial to the rational use of the space and ground of the plant and the rain water system in the factory area. Open ditch drainage or reduce the buried depth of pipelines and other advantages; but if the design is not good or the construction quality is poor, there will be problems such as overturning, leakage and so on.
天沟外排水,应以建筑的伸缩缝或沉降缝作为屋面分水线。天沟的流水长度,应结合天沟的伸缩缝布置,一般不宜大于50m,其坡度不宜小于0.003。为防止天沟末端处积水,应在女儿墙、山墙上或天沟末端设置溢流口,溢流口比天沟上檐低50~100㎜。
Drainage outside the gutter should be based on expansion joints or settlement joints of buildings. The length of the gutter should be combined with the expansion joint layout of the gutter, generally not more than 50m, and its slope should not be less than 0.003. In order to prevent water from accumulating at the end of the ditch, a spillway should be set up at the parapet wall, gable wall or the end of the ditch. The spillway is 50-100_lowerthan the eaves above the ditch.
立管直接排水至地面时,需采取防冲刷措施,在湿陷性土壤地区,不准直接排水,冰冻地区立管需采取防冻措施。
When the riser is directly drained to the ground, it is necessary to take anti-scouring measures. In collapsible soil areas, no direct drainage is allowed. In frozen areas, the riser should take anti-freezing measures.
