Description

Road ice prevention system {PREVENTING ROAD-FREEZING SYSTEM}

The present invention relates to a freezing prevention system for preventing accidents caused by freezing by installing in the freezing section of the road.

Winter snowfall and freezing of roads caused by water can cause vehicle slipping accidents and are a major factor in winter traffic accidents.

Conventionally, sand spraying or calcium chloride spraying is used as a road freezing measure, and this method is repeated every year because other solutions are not suggested, even though it is not possible to fundamentally solve the sliding accidents on ice roads. Road maintenance costs are being consumed.

Table 1 and Table 2 show the results of the traffic accidents and the material input for re-establishment work during winter season (1998.12-1999.1.23) in Deokjin-gu, Jeonju-si, Jeollabuk-do. It is very large and consumes huge manpower and cost, but its effect is weak, indicating that it is not possible to fundamentally solve the occurrence of traffic accidents caused by road ice.

Even though huge costs and manpower are consumed each year for snow removal, traffic accidents caused by freezing cannot be prevented fundamentally, and the number of casualties due to freezing is not reduced every year, and the resulting socioeconomic losses are very high nationwide. In this situation, there is an urgent need to propose a way to fundamentally prevent road freezing. As a solution to this problem, there has been proposed an anti-icing structure having a heating wire or heating concrete installed under the road surface. The structures are difficult to install and construct, and use high voltage, which is a very dangerous factor for pedestrians and vehicles when a short circuit occurs, and there is a problem that the road cracks and breaks due to a sudden temperature difference applied to the road surface.

The present invention is to solve the winter road accidents by eliminating road ice and snowfall by the circulation of hot water, and to solve the winter road accident, and easy installation and construction, and to provide a freeze protection system of a safe structure, repeated winter traffic every year It is intended to effectively prevent accidents.

To this end, the present invention is to install a heating tube in the lower part of the road surface in the interval of frequent frost accidents such as an uphill road, a curve road or a shady road so that heat dissipation is performed by each section to prevent freezing. Present a new system.

Hereinafter, the configuration and operation of the present invention will be described in detail.

According to the present invention, a heating tube (2) buried under a lane (1) is installed on the basis of a section in which freezing accidents such as an uphill road, a curve road, or a shady road are frequent, and to provide heat to the heating tube (2) for circulation. The heat supply device 3 provided for each unit and the control device 4 for controlling and operating the heat supply device are configured to radiate heat in each section of the lane.

Fig. 1 shows an example of the system configuration according to the present invention in a one-way secondary road, in which the heat pipes 2 connected to the respective heat supply devices 3 are respectively provided with independent heat supply devices 3 on both sides of the road. (1) Pass the lower part of the center and change the direction from the end of the section to the other part of the road, and continuously install it on the underside of the road and apply the freezing prevention system that is operated independently in both lanes separated by the center line (5). It is shown.

Figure 2 shows that in the case of a one-way primary road, one heat supply device is used, and the heat pipe can be configured as a single system connected to the heat supply device by making a U-turn through the driving lane to the opposite driving vehicle. Regardless of the type of road, it is applied by embedding a heating tube having a proper heat supply capacity on each lane regardless.

In the above configuration, the supplied heat is made by indirect heating by hot water, and the heat supply device is achieved by a conventional boiler device.

The heating tube has a heat dissipation property and a corrugated pipe 2a is used to prevent freezing by stretching. Antifreeze is used to prevent freezing of the circulating water.

In the case of new roads, the laying of the heat pipes is to be buried at a depth of about 30cm from the road along with the road construction.In the case of the existing roads, after cutting the road surface, the heat pipes are buried, and the heat-resistant cement is first coated with concrete. Or use the method of finishing with asphalt or constructing a block with a built-in heating tube and installing it on the cutting part of the road and then binding it using a binder or the like.

5a shows a configuration in which a block 9 including a heating tube is inserted into a groove and then bonded to the road surface with a binder 10 after cutting the road surface, using a resin-based adhesive. It is used as a method of promoting curing by mixing an appropriate amount of curing agent during construction.

5B illustrates an embodiment of the above-described block, in which an internal heating tube protrudes from both ends of the block 9, and a connecting portion 11 is formed on the protrusion to connect the connecting portions of both blocks to the joint 12. The construction is made by connecting each connection to the joint 12 while installing the block on the cut groove and filling the space with binder or concrete.

Fig. 6 shows the control device 4 of the road ice prevention system according to the above configuration, in which the control device includes a manual operation mode 13, an automatic operation mode 14, and a remote control mode 15. It is configured to control the on / off of the heat supply according to the output signal of the.

The automatic operation mode 14 is configured to operate automatically when a predetermined condition is met. The automatic operation mode 14 operates automatically when snow is detected by a sensor 14a installed outside the system. The transceiver 15a connected to the control device is directly operated by the road management station 17 using the wired / wireless network 16, and the manual operation mode 13 is operated by the decision of the patrol personnel. It is a control system that is configured together with automatic control or remote control in a way that prevents freezing of the road by operating the system when there is a risk of snowfall or accumulation.

The configuration of the control device can be integrated management of the frost prevention system installed independently for each section to reduce the cost required for maintenance, and can be operated in a variety of control methods according to the conditions to quickly respond to snowfall Will have the effect.

The present invention by the above configuration is to realize the technical idea to prevent the road from freezing by the source of heat supplied from the roadbed under the bed, each configuration described above is described as an embodiment It is not excluded that it is feasible in form.
