FAQ about Pipe Boring
Pipe boring is a system of installing pipes underground which does not use trenches. Cables and conduits can also be installed this way. Instead of digging up a trench, a bore path is made by a drilling rig designed to create shallow arcs. The main reason for using boring method instead of trenches is to decrease the effect on the environment.
Also, if the area in which the conduit is meant to pass is not suitable for digging up trenches such as in rocky areas, this would be the most appropriate method for laying down cables and pipes. Below are a few facts about this trenchless pipe installation procedure that you should know about before you choose a method.
The process has three steps. In the first step, a hole is drilled on the path which has been mapped out. This hole is designed for receiving the pipe, conduit or cable. For the second step, the hole is widened to attain the desired size. A back reamer is used for enlarging the hole. When the hole is wide enough, the pipe is strategically placed in the created hole.
This process, however, is not easy since the pipe may stick on the sides making it difficult to pull it through the hole. To prevent this from happening, a drilling fluid is used. It acts as a lubricant. The drilling fluid also washes away the debris created when the hole is made in the ground. Therefore, it prevents clogging of the created hole. This waste can be reclaimed to prevent damage to the environment. The process is pretty simple. It does not take long to install pipes with this method.
Techniques utilized in boring
1. Auger technique
In this technique, a rotating cutting head is used to form the holes. This cutting head is connected to the lead hole through a string. The soil is removed continually as the boring process continues. This process is safe since the hole is usually supported. Therefore, it is unlikely to cause any harm to workers.
2. Directional drilling
A rig is launched on the surface. It creates holes and then the pipe is steered into this hole. Drilling fluid is utilized during the process to provide lubrication and remove mud. It is the most widely used marketing techniques.
A variety of material can be used to make the pipes. These include plastics like polyethylene and PVC. They can be made of metal such as iron or steel.
These are used to make holes in the rock or soil. Drill capacities range from 1800 feet to more than 5000 feet. The type you select will be determined by the purpose of the pipe, conduit or cable.
3. Pumps and hoses
These are necessary for supplying drilling fluid at the right amount of pressure.
4. Mud Reclaimer
Its purpose is to clear out the mud created by the combination of the excavated soil and the drilling fluid. If this mud is not removed, it may clog the holes or prevent smooth steering of the pipes.
The excavator is utilized in the initial process to remove soil forcefully.
Advantages of trenchless pipe installation technology
1. It is eco-friendly
The mechanism used ensures that disturbance to the environment is very little. It excavates soil only at the surface hence damage caused will be minimal.
2. It is quicker.
Since the method eliminates the need for digging up trenches the time utilized will be shorter. The pipe is laid as the boring continues to speed up the process.
3. Saves on space
With trenching, space has to be created where the trenches will be dug. Pipe boring, on the other hand, can be done even under existing roads and buildings. It is a very economical process.
4. No need to relocate people while installing the pipe
Since boring only focuses on the surface and causes minimal disturbance to the environment, people in that area will not have to be moved during the process.
5. It is easier to rehabilitate the area.
Areas, where trenches are dug, may take months to be restructured. This is not the case with pipe boring. Within a few days or weeks, the area can be declared safe for use.
6. It is very accurate.
Since the hole is created to fit one pipe in a particular direction, high levels of accuracy can be attained.
7. The pipes are easy to repair
Pipes often leak. When this happens, the personnel will easily access the damaged part of the pipe through the two openings; the receiver and the initial hole.
8. It is a very clean method
Little debris is left after completion of the installation process since only the surface is excavated.
Disadvantages of this Process
1. It could be costly.
The equipment involved in this technique is not easy to come by so they are very expensive. This could influence the overall cost incurred during installation.
2. It can only be done in specific soil types.
Rocks with no spaces in between are the best for pipe boring. Sedimentary materials are also appropriate for the technique. Soft soils will not work well with this method. Therefore, ensure you know your soil type before choosing the boring method.
Pipe installation underground is very common today. In fact, almost all telecommunication cables, sewer lines, oil and gas lines as well as those of electricity are placed underground these days. However, the right method for putting these pipes, conduits and cables underground must be selected so that the piping gives maximum output. Pipe boring is a very promising method. It saves space, time and is very environmentally friendly. Also, it is the only method that can be utilized where trenching technique is impossible. The accuracy of piping attained with this method cannot be compared to that of trenching. Furthermore, it can be easily repaired should a problem occur after the initial installation. However, pipe boring cannot be done by just anybody. Therefore, ensure you select a reputable service provider to install your pipes underground using this technology.
