Embodiment Construction

[0034] The deicing system of the present invention comprises five parts such as (1) conductive concrete, (2) conductive material, (3) electrode, (4) power source, (5) control system, now respectively describe as follows:

[0035] (1), conductive concrete

[0036]The conductive concrete of the present invention is formed by mixing cement, aggregate, water and conductive materials. The conductive concrete preferably uses the first type or the third type cement, and its volume accounts for 12-16% of the total volume (unless Specially specified, otherwise the percentage refers to the percentage of the total volume of the conductive concrete), and the best is that the cement accounts for 14-16% of the total volume of the conductive concrete. The best aggregate is to use 10-25% fine aggregate and 10-25% coarse aggregate, and the best is to use 13-18% and 17-20% fine aggregate and coarse aggregate respectively. Contains sand and gravel, preferably the equivalent of Nabraska No. 47B....

Abstract

The invention relates to a conductive concrete de-icing system for melting ice and removing snow by combining conductive concrete and a conductive heating device. The conductive concrete materials is made of a plurality of conductive materials such as cement, aggregate, water, metal fiber, metal particles, and the like; an ice-melting and snow-removing system is formed by the supply of electric power and the connection of a control system. The conductive concrete has the advantages of good conductivity, high mechanical strength, convenient preparation and use, no environmental pollution, and forming an integral part with structure, and the like, therefore, the conductive concrete is an advanced and practical material. As the conductive concrete system is laid on the road surface, namely, under the condition that the icing and snow are on the road surface, the current is supplied to heat the conductive concrete as well as quickly and effectively melts the icing and snow on the road surface. The system is economical and practical, and can effectively prolong the service life of roads and bridges in cold areas.

Description

technical field [0001] The invention relates to a conductive concrete with a conductive heating device, in particular to a deicing system that utilizes the conductive concrete and the conductive heating device to defuse ice and accumulate snow on roads and sidewalks. Background technique [0002] Because concrete has excellent physical and mechanical properties, it has been widely used in countries all over the world. For example, a large number of concrete pavements have been built on highways, urban roads and airports. The construction and operation of these infrastructures play an important role in the overall development of the national economy. [0003] A large number of investigations and studies have shown that the quality of the road surface is an important factor affecting road traffic. The change of seasons throughout the year and the change of weather conditions affect the road surface condition, road traffic capacity and driving safety. Especially in the cold w...
