Design Requirements for Drainage Ditch1. The drainage of the workshop should be considered comprehensively with the drainage of the plant.
Different water ditches are used in different cleaning areas. For general cleaning areas and quasi-cleaning areas, open ditches are covered with stainless steel side rails. Hidden ditch must be made in high clean area.The indoor drainage (including floors) of the production workshop should be an open ditch without cover, and the open ditch should have a certain width (200～300mm), depth (150～400mm) and slope
(greater than 1%), and the drainage slope of the workshop floor Should be 1.5～2%
2. The water pipeline should maintain a certain slope and flow from the clean area to the unclean area.
The flow of sewage flows from the high clean area to the low clean area. Design a certain slope to avoid pollution caused by dirty water discharge. The slope of the main drainage pipe in the workshop should consider the location of the drainage outlet, its location and the slope of the main drainage pipe in the workshop should also consider the depth of the drainage pipe under the drainage outlet of the workshop and the reasonable location of the drainage ditch depth in the plant area.
3. The drainage pipeline should be leveled during construction.
There must be no unevenness and cracks to ensure the smooth drainage of the workshop, and there must be a certain arc at the turning point
