Anti-freezing system for roads and bridges

Abstract

The invention discloses an anti-freezing system for roads and bridges and belongs to the field of road maintenance. The anti-freezing system comprises a street lamp supporting seat, a subgrade, a supporting seat, a street lamp stand column and a mounting platform, wherein a solar panel is arranged at the upper end of the mounting platform; a lamp holder is fixedly mounted at the front end of the mounting platform; a fixed supporting block is arranged in the middle of the subgrade; a steel product supporting beam is arranged at the lower end of the subgrade; the subgrade is internally providedwith a plurality of water collection channels which are uniformly distributed; the water collection channels are mutually communicated; an anti-slipping layer is arranged on the surface of the subgrade; a water accumulation opening is formed in the supporting block. Two sides of the anti-slipping layer are obliquely arranged and an inclined angle is 5 to 8 degrees, and water flow on a bridge deckis collected into the water collection channels and then is discharged; an inclined anti-slipping layer design and a channel design of the water collection channels are adopted and the water flow on the surface can be rapidly and efficiently drained, so that the probability that the bridge deck is frozen is greatly reduced; the deicing effect of the system is improved; the anti-freezing system hasthe advantages of simple and reliable structure, energy saving and environment protection and no consumption of energy sources.

Description

technical field [0001] The invention relates to the field of highway maintenance, in particular to an anti-freezing system for highway bridges. Background technique [0002] Road icing tends to occur during the period from November to April of the following year (that is, winter and early spring). In northern China, especially in the Northeast and northern Inner Mongolia, roads often freeze. In southern China, snowfall is generally "wet snow", which often belongs to mixed water at 0-4°C, and it will become ice-water paste when it hits the ground. When the temperature drops at night, it will solidify into large pieces of ice. As long as the local winter If the minimum temperature is lower than 0°C, there may be ice on the road. As long as the temperature does not rise enough to thaw the ice, it will remain rock-solid. Generally speaking, in the twelfth lunar month of winter, when there is a large-scale strong cold air activity that causes the temperature to drop (called a c...

Problems solved by technology

Especially above bridges, once an accident occurs due to icing, it is easy to cause serious accidents, which requires the invention of a road deicing system

[0003] A Chinese patent (publication number: CN 106522088 B, announcement date: 2018.08.21) discloses an anti-freezing system for highway bridges, but in actual use, the anti-freezing system for highway bridges provided by the above documents The advantage of the system is that the invention is suitable for the installation of bridges with different lengths, improves the installation speed of the anti-freezing system, enables the anti-freezing system to have the function of utilizing solar energy, saves the energy consumption of the anti-freezing system when heating the bridge, and is environmentally friendly. The reason is that the efficiency of freezing is not high. Starting from destroying the conditions of freezing, destroying the conditions of freezing can prevent freezing. Therefore, it is necessary to invent an anti-freezing system for highway bridges.
