Description

  The present invention relates to a collection and drainage groove block used in a collection and drainage trough that is disposed in a side groove / crossing groove for collecting and draining a road, or on a side edge of a road, and has a function of collecting and draining.

  Road side ditches for collecting and draining road surface water are widely used in the form of continuous collection and drainage groove blocks made of concrete U-shaped grooves, with a rectangular lattice grating or concrete lid set on top. In addition, a collection and drainage basin that collects and drains road surface water or the like by embedding a collection and drainage groove block of a rectangular deep hole concrete block in a side edge of a road or the like and fitting a grating in an upper opening is widespread.

  And in the snowy area, snow removal means is used to throw road area snow into the road side ditch and to pile up. Therefore, as a snow melting means for promoting snow melting of the snow removal snow and flowing into the side ditch, the background art shown in Patent Documents 1 and 2 is used. Artificial snow melting means for melting snow by embedding a heating wire in the concrete wall of the side groove block of a concrete rectangular tube with an inlet for road surface water on the top surface (patent document) 1) or artificial snow melting means (Patent Document 2) for melting snow by burying a hot water pipe through which hot water for melting snow from a hot water generating heat source device is passed in a concrete lid of a road side ditch and raising the temperature of the concrete lid. .

JP 2004-36244 A Japanese Patent Laid-Open No. 10-152883

  The artificial snow melting means of the background art has a form in which the temperature of the entire concrete body is increased by disposing a heating wire or a hot water pipe inside the concrete body having a low heat conductivity and increasing the heat capacity. In addition, the heat calorie required to heat and maintain the entire concrete body to a state where snow melting is possible is extremely large, and the back surface and side circumference of the concrete block where the snow melting function is unnecessary are also uniformly heated. Therefore, a lot of heat calories are indispensable, and the snow melting cost becomes very large.

  Furthermore, it takes a long time to raise the temperature of the low thermal conductivity concrete body to a state where snow melting is possible by using a heating wire or a hot water pipe with a temperature raising function. Therefore, there is a problem that the temperature of the concrete block is predicted and the temperature is maintained, and the cost of melting snow and the complexity of snow melting management are complicated in this respect.

  The present invention provides a drainage groove block having a special snow melting function by solving the problems of the background art described above.

  The drainage / drainage groove block of the present invention that solves the above technical problems is “in a drainage / drainage groove block comprising a concrete U / groove main body or a concrete drainage / drainage main body, the U-shaped groove body or the drainage / drainage body” Is characterized by the basic structure of “a structure in which a metal heating / radiating plate is externally fitted on the back surface of the heat generating portion formed by wiring a heating wire that serves as a power source for general road wiring.

  That is, the drainage groove block of the present invention having the above-described configuration is provided with an exothermic heating part in which a heating wire is wired on the back surface of a metal plate having excellent thermal conductivity at the upper end of a drainage groove block made of a concrete body. Constructed in the above-mentioned heating radiator plate of "direct heating by heating wire", and the heating radiator plate functions as a snow melting part of a drainage housing such as a road side ditch or road to achieve quick, low cost and high efficiency snow melting It consists of thought.

  And from the technical intention of further improving the specific action, the drainage groove block of the present invention of the basic form can be formed into a set of forms in which the drainage block can be connected in series with each other, An automatic temperature control unit that maintains the temperature of snowmelt at an appropriate temperature regardless of the outside air temperature, or a heat-dissipating plate on the opposite side of the U-shaped groove and connected to the inner circumference of the U-shaped groove A mode in which a heat conduction bar in the form of an anchor bolt is provided to attach a groove bottom heating plate or to conduct heat to the concrete part of the main body to heat the groove bottom.

  The collecting / draining groove block of the present invention of the basic form is formed by fitting a heating heat radiating plate made of a metal plate with a heating wire on the back surface to the periphery of the upper end opening. The road side ditch, etc. used has an effective snow melting outflow action that melts snow quickly and efficiently by the heating heat sink when the snow removed from the road area snow is thrown in or stacked, and naturally flows into the groove.

  And when the grating of the metal square lattice is attached to the upper end and used as a drainage drainage basin arranged in a keyway such as a road gutter or road, the heating heat sink and the grating function as an integral metal body with high thermal conductivity. Therefore, the snow removal snow accumulated on the grating is melted quickly and effectively, and the snow melting outflow function of the present invention functions more remarkably.

  And since the said heat radiating plate is a direct heating form by the heating wire of back surface arrangement | positioning, the heat conduction efficiency to the heating radiating plate of the generated heat of this heating wire is very high, and the consumption cost of the electric calorie for melting snow is low. It is much lower than that of the background art.

  In addition, since the heating heat sink heats up from the switch-on to the heating wire to a state where snow melting is possible, it is not necessary to energize the snow melting needs in advance, and it is easy to manage snow melting countermeasures. At the same time, wasteful consumption of snow melting power can be prevented. There are the above main effects.
