3 Tips When Laying Down Underground Pipes

underground pipe laying

Underground pipe laying is not as simple as laying pipes beneath the dirt and hoping for the best. There are many intricacies that are often overlooked in lieu of faster completion times or cost reduction. Yet that need not be the case.


If you are a constructor looking to improve your efficiency without dropping in productivity, this list of tips may just be for you.


Here are 3 tips to improve your underground pipe laying procedure.


Determine The Number Of Fittings Required

Before beginning operations, there is an abundance of preliminary planning that goes into determining the pipe type to be used. This aspect is often overlooked as many contractors opt to order the required fittings whilst ordering the pipes.


The correct procedure should be to first determine the number of fittings required. This can be done through the use of a plumbing plan. From the said plan, contractors can highlight each branching pipe with a unique colour. This includes fittings such as bends, reducing bends, reducing tees and cross fittings. By thoroughly examining what the plumbing plan requires, contractors can have a clear understanding of what fittings are required and their numerical value.


In addition, this planning process is great for determining the length of the pipes needed. Professionals recommend purchasing pipes that are slightly higher values than calculated. This additional length gives extra leeway for additional practices and corrections in the event of an error.


Constructors can easily modify pipe length by cutting it with either a hacksaw or fine-toothed saw. Once adjustments are made, it is important to chamfer the pipe before joining them together. This is because a freshly cut pipe will have sharp ends that are rough and sharp, making it easy for it to break the rubber seal on the pipes which in turn causes leakage.


After using a chamfering tool to file and smoothen the end, the seal in the socket needs to be lubricated using pipe lubricant. Once complete, push the pipe firmly into the socket till it stops, then pull it back 10mm to give leeway for movement and expansion.


Plot A Clear Map Of The Worksite

Upon arriving at the worksite, it is a good idea to give the place a rundown by navigating the area. By using a structural plan or plumbing design, contractors can determine the locations where pipes pass through or where chambers and fittings are meant to be fixed.


Appliances and septic tanks can also be strategically placed based on the plumbing or structural plan. This ensures that work goes smoothly as constructors have a clear view of how and where materials should be placed, removing the possibility of obstruction during operations.


Determine final floor level / Specific Points Of Appliances

Once the layout of the worksite has been evaluated, the next step is to determine the final floor level of the area. This helps to ensure that the completed piping will not cause future issues when fixing appliances.


The final floor level is the height of the surface of the concrete floor from the soil. Determining the final floor level ensures that whatever is fixed does not go beyond the height of the floor or goes too deep into the concrete floor.


To simplify this process, here are some simple steps to determining the final floor level.


1) Locate each point where appliances will be fixed.

2)Mark those areas with pegs to increase precision

3)Make a note of the furthest point from the final outlet

4)The depth of that point should then be adjusted to fit the depth of the pipe, and then the slope can begin from there onwards.
