This field of activity is the main production programme of our company. Viamont DSP a.s., has been involved in constructions, reconstructions and maintenance of track structure since it was founded. We have gradually included other activities and fields in our production programme with expansion of company operation in other segments of transport construction.
Viamont DSP a.s. implements work deliveries in all categories:
They usually consist of one predominant main operation eliminating the causes of the most serious faults ascertained on the basis of an evaluation of the results of diagnostics and other work which augments it or is caused by this activity.
Our company performs these decisive operations:
Reconstruction of track structure is essentially replacement of worn material of the track structure with new or regenerated material. We perform the reconstruction of track sections and reconstruction of capping.
Decisive work during reconstruction of track structure:
One integral part of the reconstruction of track structure is the performance of adjustments to GPK inserted tracks and switches, welding and establishment of continuous welded rail, adding ballast and adjusting bed to profile, adjustment of beds, ditches and drainage, dismantling of old track grid, including its categorisation, and processing of project documentation amended according to the true state of performance of the construction in graphic and digital form. The high-quality performance of all the aforementioned activities is conditional on extensive technical infrastructure. In our case this is ensured by the assembly base with a high standard of equipment in Chabařovice. The base has a siding with gantry cranes and own locotractor units with linkage to ČD. In order to deal with unexpected events Viamont DSP a.s. has its own material equipment for track structure at the base, and it has it in such a volume that on an operative basis it is possible to eliminate any accident both on track sections and switches. We perform the individual constructions via mobile construction-assembly gangs equipped with high-quality small equipment. Qualified site managers and foremen ensure the engineering aspect of constructions, and they participate in the preparation, implementation and subsequent approval for use of the individual constructions.
Work on railway beds is an integral part of work on all rail lines. The company Viamont DSP a. s. performs all types of this repair work, i.e., maintenance, repairs, redevelopment, reconstruction and modernisation. The functionality of the railway bed body constructions and the equipment of the railway bed, its load-bearing capacity and stability is ensured by this work.
One of the most commonly performed items of work on railway bed is increasing the load-bearing capacity and stability of the railway bed body. One essential precondition for performing this work is high-quality geo-technical survey and project documentation designating a suitable type of construction of sleeper bed. Our company performs or ensures all types of this work
● creation of ground base from non-cohesive, frost-proof and permeable soils
Other very common repair work includes repairs to or creation of drainage features (ditches, ditch walls, chutes, gutters, drains, slope ribs etc.), reinforcing slopes of soil body with vegetation protection (topsoil, hydroseeding) or with technical protection (paving, facing, gabions, grids, mats), maintenance and repair to supporting and breast walls, platforms and fencing.
The modernisation and optimisation of railway tracks and corridors represents the most technically complex constructions in the field of transport engineering. These constructions are made all the more difficult by the very strict conditions for minimum restriction of existing traffic during the period of implementation. The organisational unit for the implementation and management of corridor constructions of the company Viamont DSP a.s. consists of highly qualified workers with several years of experience in these constructions. Through good coordination and management of the performance of own production fields of the company Viamont DSP a.s. (track constructions, traction current lines) and rail transport capacities the very best preconditions are established for the implementation of the integrated parts of these constructions, which are amongst the most significant investment projects.
