Micro-Trenching with the trenching machines from LiBa

Glass fibre is the future. Data is transmitted much faster than is possible with copper.  Not only the Internet, but also radio, TV, telephone and much more will become much faster through fibre optics. Thanks to the latest technology and processes, it is possible to lay fibre optic cables underground in a very short time. This means, for example, that small excavated trenches of minimal width can be dug and closed again in one day.

Micro Trenching – Lay fibre optic cables even more effectively with a trencher!

Micro Trenching, or Mini Trenching, is a widespread technique that allows for example to lay fibre optic cables quickly and cheaply. The advantages: Micro Trenching causes little damage to the environment, as the construction sites are smaller and therefore take less time, so there are fewer traffic obstructions and less air pollution through exhaust fumes. Projects have also shown that the use of micro-trenching can significantly reduce both costs and working time.

Instead of laboriously digging up the roads with an excavator, micro-trenching simply involves cutting a narrow slot directly at the curb, allowing the micro pipes or fibre optic cables, but also other cables or pipes, to be laid. The name is derived from the English words „micro“ and „trenching“, which in English means something like „tiny trench“. So the name already tells you what kind of technology is involved.

The advantage of Micro-Trenching

Micro-trenching is faster and more efficient, and in general is economically much more localised than conventional civil engineering methods. The first 100 metres can be laid within one morning, which is not possible with an excavator. In this case, a special milling machine will be much faster than an excavator. Because, as already mentioned, it is sufficient for the fibre optic cable if Micro-Trenching cuts narrow trenches into the asphalt. How to do this is explained here.

Fast and cost-effective laying of fibre optic cables

This type of milling is particularly popular in towns and housing estates. The construction sites should and must be kept quite small in order not to disturb the residents and not to obstruct the traffic flow too much. In order to be able to guarantee this, the trench cutters do not have to be too large and immobile. For this reason we have special machines that we offer for this work.

Our favourite machine for such construction sites is the GM 500 R. This is a milling wheel which can be used very effectively in the city due to its light weight of 1200 kg. The light weight also makes it possible to dig perfect trenches in the asphalt, making micro-trenching ideal. A big advantage of this machine is the already mentioned lightness. This enables the customer to attach the machine to a carrier that is also quite light and compact.

All our machines are produced on site and are made of strong and high quality steel. With the Gm 500 R, we have developed a machine that is designed to simplify work in villages or towns. We have used all our experience to make the trencher as flexible as possible but also robust enough. The result is a machine that is very flexible in cities, because it is very light and can be moved hydraulically. On the other hand it is also robust enough to dig an ideal trench through asphalt and stones. Whether it’s fibreglass laying, micro trenching or sewage pipes, our milling wheel will help you on any construction site.

LIBA trencher GM4 as carrier machine

In combination we are happy to offer our GM 4. This is an excellent carrier and is also quite light and agile. Of course the machine can also be used on other carriers. Already a weight of approx. 3500 KG is sufficient to work reasonably with this machine. The hydraulic power should be possible at 80 litres at 300 bar.

What does micro-trenching depend on?

The GM 500 R milling wheel for perfect glass fibre installation

• Unlike conventional trenching machines, our milling wheel allows you to work on much narrower and smaller construction sites
• Especially when laying fibre optic cables, clean trenches are very important in order not to damage the cable
• Even through asphalt and stones, this milling wheel easily cuts a clean trench for optimum cable laying
• Another special feature that makes the milling wheel even more flexible is the hydraulic side offset on the rear cross beam
• You can therefore move your milling wheel hydraulically from right to left, depending on which side the construction site is on
• This is an enormous advantage when they have to mill in inaccessible areas
• Thanks to this lateral offset, they can, for example, easily drive on the left-hand side of their carrier while milling on the right-hand side
• This is sufficient for micro trenching as well as for glass fibre laying or wider cables

Since micro-trenching is all about digging a small but clean trench, our milling wheel is ideal for this task. Due to the stability and robustness of this machine, perfect trenches, even in asphalt, are no problem. Furthermore, we also offer an installation shaft for cable laying. This enables you to work even faster and more effectively. The cable to be laid is laid through this shaft directly behind the milling machine, so that you can mill and lay the cable in one go. This saves time and therefore costs. It also protects the environment, as you can finish your construction site faster and traffic can start moving again more quickly. This reduces the emission of exhaust gases. For further questions, click here!

Minimum trench, maximum speed!

If you decide to go for micro-trenching, you will have some advantages worth mentioning. This procedure is not only more local from an economic point of view but also ecological. As already mentioned, there are some advantages of micro-trenching that are very beneficial to the environment. For example, because the work is completed more quickly, traffic is resumed more quickly, which means that less exhaust gases are released.

In this method, narrow trenches and slots are made in the asphalt using milling technology. This means that only a small trench width and depth is required and enables the rapid completion of glass fibre routes. In addition to micro-trenching, empty conduits are also to be used and expanded above ground.

Trenching is one of several special laying techniques and is usually always used in combination with other techniques. Important for a sensible use is the differentiation of the methods with regard to trench width and trench depth. In addition, the restoration of the surfaces is also important.

Trenching involves digging a trench only up to 30 cm deep into the pavement or road where conventional cable protection pipes or flat liners with the corresponding fibre optic cables are laid. The cable trench is filled in immediately after laying. A frost-proof, temporarily flowable, self-compacting building material is then used as the backfill material. Thus, traffic obstructions are only of short duration.

By the way, there are several trenching methods, namely micro, mini and macro trenching. These differ in the depth and width of the realised milling slots and in the cutting or milling technology used.

Milling of cable trenches in civil engineering – only minor impairments with optimum efficiency

The environmentally friendly alternative to excavators are trench milling, because they ensure the best workload when milling cable ditches without causing major damage in the sense of nature conservation.

When milling the cable trenches, the main focus is on the special variants of cable laying. In any case, a well thought-out project involves the professional milling of cable trenches. It is no less important that the milling of cable ditches goes through the stage without major damage to the land and above all in an environmentally compliant manner. You want more details about our trench cutters? We will be happy to provide you with the necessary documents on request.

Precise milling with LiBa

A clean trench is essential for cable laying. Many machines have the problem that they cannot pull clean trenches and thus half of the excavated material falls back into the ditch. This is an important feature, especially when milling cable trenches. Our machines guarantee you a clean trench!

The reason for this is, on the one hand, our many years of experience, in which we were able to perfect this process. On the other hand, all our machines are tested in our in-house line in order to solve such problems before a machine goes into production. Thus, we can guarantee that our trenches are always clean and precise milled so that they can carry out their project without any problems.

Working ecologically when milling cable trenches

The extremely environmentally friendly alternative to the excavator is the trench cutter, because it guarantees a maximum workload when milling cable ditches without major impairments within the meaning of the Nature Conservation Act. A central focus of activity in construction is the laying of glass fibers in various versions. The services of the all-rounder include not only the milling of the cable trenches, but also an environmentally friendly excavation of the floor. The individual equipment of our trench cutters is available on request.

Construction and cable laying in a fast-track process. Thanks to state-of-the-art technology and processes, the fiber optic cables are laid underground within a very short time. Small excavated trenches of minimized width are usually closed again on the same day. In many cases, civil engineering work can even be dispensed with altogether, as empty pipes for the glass fibers can be pulled under the pavement, for example by means of a rinsing drilling process. In this way, disturbances for the residents are also kept to a minimum. This is of great importance when working in residential regions.

If there is work in a housing estate, it is important to work as quietly and quickly as possible. These demands can be made with the so-called „micro-trenching“. In this procedure, a small trench is milled into the asphalt. The trench is sufficient to lay a fiber optic cable, but is also kept as small as possible.

The difference to conventional milling is the depth of the trench. While it is better to mill a little deeper in the countryside, milling of cable ditches in the city is often not possible. Then the „micro-trenching“ comes into play. Due to the low digging depth, the trench can also be drawn faster. The result is faster work and thus earlier completion of the construction site.

Advantage by quality

One of our greatest advantages besides experience and service is our quality. Our machines are built and completed here on site. Perfection is very important to us in production. We do not take the cheapest material, but the best. For this reason, our machines are also excellent in every area.

Cheap material is certainly cheaper to purchase, but damage when milling cable ditches and unclean digging of the trenches are almost inevitable. In the longer term, a stable machine is therefore much more lucrative. This way of thinking accompanies us to the beginning of LiBa and has given us a good reputation over the years, which we want to keep with all our efforts. Therefore, we would be very happy to convince you of our machines and to welcome you as a customer! For more information please click here!
