👉UNDERSTANDING DRAINAGE SETTING OUT AND CONSTRUCTION
🏷Effective drainage systems are critical for managing stormwater runoff and preventing flooding in urban and rural areas.
💫Properly constructed drainage systems ensure the safe removal of excess water, protecting infrastructure and the environment.
💫Construction techniques/Activities description
▪️Carry out project assessment by evaluating the drainage requirements based on the project plans and specifications and also understanding the intended function, capacity, and location of the drainage system.
▪️Design analysis is by carrying out site assessment which include identifying topography, soil types, and water flow patterns, gradients, aninlet/outlet locations.
▪️Determining drainage requirements based on local regulations and rainfall data.
▪️Setting out
▪️Set up benchmarks to establish a reference level at a known elevation
▪️Establishing profile
▪️Establish the levels
▪️Ensuring proper slope and alignment to facilitate water flow
▪️Excavation and trenches
▪️Preparation of drainage bed
▪️Blinding of 50mm - 70mm thick to receive drainage base
▪️Laying of reinforcement baskets
▪️Laying of concrete cover blocks
▪️Installation of formwork
▪️Preparation of materials
▪️Design mix (1:2:4) used with proper amount of water.
▪️Carry out slump test to ascertain concrete workability
▪️Casting the base and walls of drainage with vibrated concrete
▪️Compaction and backfilling
▪️de-shuttering
▪️Allow for curing
▪️Carry out QA and inspection during and after.
