How the slope system in pipes and drains works and how to check and maintain the same at construction sites? What are the methods for the same? What is the mean of 1:4 slope for pipes and drains?

Aditya,
Here you are asking about Life Cycle Assessment (LCA) of structure.
The life span of structure will vary according to the type of structure.
There is no formula available to calculate the life span of any structure.
Different parameters we should take into mind while doing a calculation of life span of structure, they are as follows;
Building Construction Material:
- RCC structure
Structural Design:
- Mostly influencing parameter.
- Vary as per Building Construction Material.
The locality of structure construction: E
- Earthquake-prone area
- HFL (High Flood Level) zone
Height of structure.
Kindly noted that I have attached one photo of the life span of various structures.

Slopes in pipes and drains are decided by quantity of water or wastewater to be transported through it by the action of gravity in cumecs. Following things influence the slopes of drains and pipes:
1. Quantity of water to be transported
2. Size or diameter of the pipe
3. Distance the water to be carried
4. Velocity or the pressure required for the water at the outlet, if any
Slopes of drains and pipes at construction site is checked by dumpy level or level machines. For the same, you have to calculate depth of pipes at different intervals.
Suppose, 1:4 slope of the pipe is required as per drawing (as mentioned by you), then the depth of pipe at should have a difference of 1 m from start of the pipe to the end of pipe at 4m. If you want to know the depth of pipe at 2m length, then it will be half of the end position, i.e. 0.5m. These are calculated based on triangle.
Slopes are always mentioned w.r.t. a reference point. Consider your reference point as a levelled surface. Then length of the pipe required will be length of the triangle, base will be the depth required from the start to end of the pipe. Now you can divide the triangle at different point and calculate the depth required at different locations of the pipeline or drain system.
I will provide your more details with figures soon.
