Today, the problem of congestion in cable ducts is becoming more and more urgent, which can be solved with the help of microtrench laying of fiber optic cables.
Brief information about the asphalt plastic sewer stacker (trencher) is presented. He cuts the asphalt in the city with a cutter to a depth of 40 cm, lays plastic pipes and fills the gap with high-strength concrete. Obstacles with this method of laying can only be tram rails and hatches. The top of the gap is first temporarily closed with a special tape, then laid with asphalt. Pavement restoration - complete and hardened at the cutting site. Sewerage construction rate up to 500 m per shift.
Improving telecommunication equipment can significantly reduce the area occupied by station equipment, while repeatedly increasing capacity.
Regarding linear structures, such trends, unfortunately, are practically not observed. The development of networks of telecom operators, as well as departmental networks leads to the fact that the existing cable ducts are overloaded, and additional cabling is impossible. In addition, it should be borne in mind that fiber-optic cables must be laid in the free channels of cable ducts, into which other fiber-optic cables can subsequently be laid. In the channel of cable ducts occupied by a cable with metal conductors, joint laying of fiber-optic cables is allowed only in a protective polyethylene tube. However, often in the channels there is no place for laying cables in polyethylene pipes. In such a situation, it is necessary to carry out the reporting of cable ducts, and this is a very expensive procedure. Most often, it becomes necessary to report channels in the central regions, which are already oversaturated with underground communications (these are, as a rule, areas with high business activity).
It should be noted that the gap entails numerous inconveniences: it creates obstacles to the movement of vehicles and pedestrians, worsens the appearance of the streets. At intersections with communications of third-party organizations, it is necessary to involve representatives of these organizations. Work often has to be done on a tight schedule, including at night. For pedestrians to move through the zones of disruption, temporary crossings with fences are arranged, and lighting is provided at night. In addition, at the end of the work, re-cultivation measures are carried out, as well as restoration of the road surface (asphalting, laying of tiles, etc.). Current guidelines recommend manual digging of trenches and foundation pits in cramped urban areas. This creates additional problems. especially in winter. The city authorities are reluctant to allow digging in the central areas of the city. Thus, there is a whole range of problems that impede the development of wired networks in areas where they are most needed. The search for solutions to these problems makes us turn to the experience of foreign partners. One of the effective methods is the use of microtrench laying of fiber optic cables.
Microtrenching mechanisms
The technique of microtrench laying is based on the use of specialized mechanisms. They are a milling cutter on the tractor chassis for removing pavement and a device for removing dust, sand, gravel and other small fractions. These mechanisms can be combined into one or, conversely, divided, accordingly distributing the technological operation of preparing the trench for cable installation in two stages - opening the asphalt and cleaning the microtrench. As a cleaning device, a compressor can be used, as well as a vacuum or water pump. Accordingly, foreign particles are blown out by the air stream, sucked off or washed out by the water stream, which is supplied under pressure.
As a rule, cable laying in the ground is carried out in a trench to a depth of 1.2 m (except for rocky and other dense soils of category IV and above) in accordance with applicable standards. Such a depth is considered sufficient to reliably protect the line-cable structures operated outdoors, from unauthorized access and environmental factors. In urban conditions, cable management is being built to streamline communications, which provides additional protection for line-cable structures.

Various fiber optic cable developers offer different technology options for cable laying in a microtrench. These options have a common technological operation - deepening. The idea of microtrench technology is to provide reliable cable protection with a significant reduction in earthworks. An additional protection against the most likely external mechanical and temperature effects is the roadway itself.
