An electric heating ice and snow melting bridge deck structure and its construction method

Abstract

The invention discloses a bridge deck structure with a function of ice and snow are melted through electrical heating. A bridge deck is sequentially provided with a cement concrete bridge deck slab, areinforced concrete leveling layer and a bituminous concrete surface layer from bottom to top, and temperature detectors and humidity detectors are arranged on the two sides of the bridge deck; arrangement holes are distributed in the upper surface of the reinforced concrete leveling layer in a preset arrangement mode, the arrangement holes are preformed by using a template, electromagnetic heaters are arranged in the arrangement holes respectively, the electromagnetic heaters are mutually electrically connected, and the electromagnetic heaters are connected with an external power supply through a high-frequency current generator to form a bridge-deck electromagnetic heating system. According to the bridge deck structure, the electromagnetic heating system is arranged on the upper surfaceof the reinforced concrete leveling layer so that the electromagnetic heaters can be prevented from being affected by vehicle load or external environments while it can be ensured that the energy ofthe electromagnetic heating system is efficiently used for melting work of ice and snow on a road surface, and the bridge deck structure damage caused by temperature gradients can be reduced.

Description

Technical field [0001] The invention relates to the field of ice and snow melting on bridge decks, in particular to an electrically heated ice and snow melting bridge deck structure and a construction method thereof. Background technique [0002] In snow disasters or frozen areas, roads, airport pavements, and bridge decks will often experience snow and freezing. At the same time, the incidence of vehicle accidents in special areas such as large longitudinal slopes, bridge ramps, and turns is also on the rise, which seriously affects the normalcy of residents Travel, and even cause life danger. Therefore, the study of timely melting of ice and snow on roads is of great significance to people's normal life and property safety. At present, the common ways of melting snow and ice on roads mainly include the following: [0003] (1) Manually remove ice and snow. Manual snow removal refers to the use of simple tools such as shovels and shovels to remove snow from the road area. This ...
