Underground pipes offer several advantages over aboveground piping systems.
First, it protects pipes from extreme weather conditions, physical damage, UV radiation and other environmental factors that can affect their condition and lifespan. Underground installations save space, making urban planning and landscaping more efficient. They also contribute to a cleaner and more aesthetically pleasing environment by eliminating visible clutter.
According to reputable pipe installation companies in the UAE, this option reduces the risk of accidental damage from human activities, including construction and vandalism, as well. Moreover, underground placement ensures a more stable temperature, preventing issues related to freezing or overheating, which can cause pipes to burst or leak.
Underground pipe installations can improve safety and reliability and support the efficient and sustainable management of essential services, including water, sewage and gas.
A Guide to Installing Underground Pipes
Proper installation of underground pipes is crucial for preventing leaks, ensuring efficient fluid flow and helping you avoid costly repairs. Also, correctly installed pipes protect against environmental damage, support the piping system’s long-term functionality, help safeguard public health and ensure regulatory compliance.
If you are involved in an underground pipe installation project, ensure its proper setup by taking note of these tips:
1. Create a project plan.
A detailed, well-thought-out plan is essential for a successful underground pipe-laying project.
The plan should consider the project purpose, soil conditions and load-bearing requirements. Once you have taken these into consideration, you can look into the other key factors, such as piping material and size and route planning.
To implement a successful underground piping project, you need to work with a seasoned civil engineer who will evaluate the site thoroughly and other project requirements and integrate them into the installation design.
2. Select the right pipes for the project.
There are different types of pipes suitable for underground installation. These include steel, copper, cast iron and PVC pipes. You should choose the right material to ensure the piping system’s functionality, longevity and cost-effectiveness.
The type of fluid passing through the piping system is the most important factor to consider when choosing the pipe material since different substances have specific transportation requirements. For instance, gas pipes are typically made of black steel since they are tough and corrosion-resistant.
Each material has its own strengths and weaknesses, so you should study each one to ensure you select the most suitable for your underground piping project.
Among the various options, PVC pipes stand out as a superior choice for underground installation. They are known for their high strength-to-weight ratio, making them easy to handle and install.
These pipes are also resistant to corrosion and chemical reactions, giving them a longer lifespan than metal pipes. Additionally, PVC pipes are smooth inside, which effectively reduces friction and enhances the flow of liquid.
The affordability and low maintenance requirements of PVC pipes also make them a cost-effective solution for underground piping projects.
3. Prioritize site preparation.
Proper site preparation involves clearing the area of obstructions, conducting soil tests, and marking and protecting utility lines to avoid damaging them. It includes leveling the ground and creating a stable trench or bore path.
A well-prepared site facilitates smoother installation, lowers the risk of delays and enhances worker safety. These steps help prevent issues such as pipe misalignment, leakage, and structural failures.
By thoroughly preparing the site, you can ensure the success of your project and the functionality and longevity of your underground piping system.
4. Choose the most suitable underground pipe installation method.
Different methods are commonly used in installing an underground piping system, each suited to specific project requirements and environmental conditions.
Below are the most commonly used methods:
● Trenching
This method involves digging a continuous trench along the path where the pipe will be laid. It is a straightforward process commonly used for transporting different types of liquid, including water, sewer and gas.
Trenching gives you and everyone working on the project a clear view of the pipe during installation. Pipes installed using this method are also easy to inspect and repair when needed.
However, trenching can cause surface disruption, which can affect traffic and landscapes. It also requires proper shoring to prevent the trenches from collapsing.
● Open-cut method
This traditional method involves excavating a trench, laying the pipe and then backfilling the trench.
The open-cut process is straightforward and cost-efficient since it does not use any specialized equipment. However, it can be more time-consuming, especially if long pipelines need to be installed. It can also cause significant disruption to the surface and surrounding areas.
● Horizontal directional drilling (HDD)
HDD is a trenchless method in which a drilling rig creates a small pilot hole along a predetermined path. The hole is then enlarged to allow the workers to pull the pipe through it.
This method is ideal for urban areas since it offers minimal surface disruption, thereby reducing the impact on traffic and existing structures. Compared to open trenching, it has less impact on the surrounding environment.
HDD is usually more expensive than trenching since it requires specialized equipment and skilled operators.
● Pipe jacking and microtunneling
Pipe jacking involves pushing the pipes into the ground behind a shield machine, which cuts through the soil. On the other hand, microtunneling is a type of pipe jacking suitable for smaller diameter pipes that can be installed using remote-controlled machines.
These methods do not require large ground excavations, making them less disruptive and safer options for highly frequented areas. However, since they involve the use of advanced equipment, they can be expensive.
Unfortunately, pipe jacking and microtunneling are also unsuitable for all soil conditions, such as those with high water content.
5. Conduct testing and quality inspection.
Testing and inspecting for quality assurance during underground pipe installation allows you and your team to detect potential issues such as leaks, weak joints, and improper alignment.
Pressure testing verifies the pipe’s ability to handle operational loads, while CCTV pipe inspections enable you to conduct internal examinations to identify any defects or blockages.
Conducting testing and quality inspection ensures your underground piping project complies with industry standards and regulations, providing you peace of mind. It also helps protect the public’s health and safety.
Whether you’re installing underground pipes under commercial spaces or outdoor areas, follow these tips to ensure a successful and problem-free project.
