Equipment for Construction of Reinforced Ice Crossings

摘要

The majority of Russia's Northern regions have neither roads nor bridges. Rapid development of the oil and gas industry requires constant development of the roads network, which, in turn, is associated with huge costs. One of the solutions to this problem might be the construction of temporary roads and ice crossings that would operate in the winter. This paper considers the questions of increasing efficiency of building ice crossings through the use of an ingenious design of a two-phase thermo-siphon with the possibility to use it repeatedly in building ice crossings within only one winter. It describes the new design of ice crossing, and the schematics of the device for extracting thermo-siphons is proposed. It is proposed to use a thermal siphon with a constant radius of curvature. This shape allows to extract the thermo-siphon with less effort without breaking the integrity of the built-up ice and the thermo-siphon itself, which allows using it repeatedly throughout the winter period. In this paper a new unit for extracting is proposed, which consists of two driving rollers and one retaining roller located on the opposite sides of the thermo-siphon to ensure better retention and downforce. The rollers are driven from the technological machine through mechanical or hydraulic transmission. The use of proposed measures makes it possible to reduce the time of reinforcing an ice crossing, and to reduce complexity of ice roads maintenance.
