Description

[0001] Snow melting block with enhanced water permeability [

More particularly, the present invention relates to a snow block, which is capable of quickly thawing and discharging it to the ground when it is snowed and iced on a concrete block forming a car or a roadway, The present invention relates to a snow block having an increased water permeability, which is capable of shortening the surface discharge time of ice water and preventing re-icing of ice water and preventing splashing of water on the ice block.

If freezing occurs on the sidewalk block due to snow, rain, etc. during the winter season, the rate of falling falls is higher than usual. In order to prevent this, conventionally, a method of snow removal using solar heat and sunlight, a method of spreading calcium chloride, a method of spreading salt or sand and thawing, and a method of heating and heating the ground through heat rays have been used.

Among the above-mentioned methods, the method using the chloride-based snow remover causes additional damage such as pollution of fruit trees, crops and soil around the road due to the execution of the snow removal work, thereby reducing the use of domestic and foreign chloride- As a method, there are methods to reduce damage through the use of environmentally friendly snow remover, and a method of spraying an antiperspirant to prevent snow accumulation before snowing, but it is hardly used because of high unit price.

In this case, the snow remnants used for the snow removal are mainly NaCl and CaCl 2 , and the chlorine ions contained in the snow remover are subjected to freezing and thawing in the concrete exposed to the atmosphere, Thermal shock is a major cause of accelerated early deterioration. Especially, the road concrete structures affected by repeated traffic freezing and thawing by the snow removers have severe damage, and surface scaling, D-line cracking, pop-out -Out), spalling, etc., the durability of the structure is severely damaged, so that not only the snow removal cost but also the road recovery cost is added.

In the meantime, a method of reducing damages by blocking the snow removing agent through a heat melting package (snow melting cable) which can be treated at the early stage during snowing by using hot wire or heater among other methods has been developed. However, It is required to develop an eco-friendly snowmelt system based on new and renewable energy because it has high disadvantages such as high initial installation cost, high power consumption due to operation, and premature damage of road pavement.

In another method using solar and sunlight, Japanese Laid-Open Patent Publication No. 10-2014-0017366 discloses a road icing prevention system including a heat generating panel assembly having a heat ray that receives electricity from sunlight and generates heat However, such a method using sunlight is ineffective on snowy days, especially when snowfall continues, and when soil or dust is piled up on the light-collecting surface, the efficiency is rapidly lowered and the cost efficiency is low. In addition, this is merely a means of merely releasing means for solving freezing by transmitting heat to the road surface, and there is a concern that such an electric device is difficult to maintain and repair because of a concern about breakdown such as disconnection or malfunction.

Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made in order to solve the above-mentioned problems of the prior art, and it is an object of the present invention to provide a concrete block, There is an object to provide a snow block having an increased water permeability, which is capable of shortening the time required for discharging the surface of the sea water to prevent re-icing of sea water and preventing splashing of water on the block.

In order to achieve the above object, the present invention provides an upper concrete layer 10 formed of thermally conductive concrete; A pipe 20 inserted to the inside of the upper concrete layer 10 to provide a path through which the fluid can flow and an inlet 25 and an outlet 26 exposed to the outer surface of the upper concrete layer 10, ); A plurality of through holes 30 formed on the upper concrete layer 10 in a vertical direction between the pipes 20 and a water permeable block 40 inserted into the through holes 30; And a lower concrete layer (50) provided on the lower part of the upper concrete layer (10) with an area generally the same as that of the upper concrete layer (10). do.

At this time, the upper concrete layer 10 and the lower concrete layer 50 are coupled to each other with a protrusion and a groove structure.

The lower concrete layer 50 is further provided with an exhaust hole 54 communicating with the ground to facilitate discharge of the fluid flowing through the water-permeable block 40.

In addition, the water-permeable block 40 and the lower concrete layer 50 are coupled to each other with a protrusion and a groove structure.

The upper surface of the upper concrete layer 10 is formed with a gradient S that gradually decreases in a direction in which the water-permeable block 40 is coupled.

The pipe 20 is provided with a connection pipe 60 which is positioned so that the inlet and the outlet are exposed and facing each other on the facing surface of the adjacent upper concrete layer 10 and inserted into the opposite inlet and outlet So that the side portions of the facing upper concrete layer 10 are in close contact with each other.

The through hole 30 is formed in the same shape as the cross-sectional area of the water-permeable block 40, and a step groove portion 56 is formed on the upper side of the discharge hole 54 so that the water- .

The water-permeable block 40 has grooves 41 for insertion of a force on the upper surface of the water-permeable block 40 so as to be easily separated from the through holes 30 of the upper concrete layer 10 .

When the snow-melting block having increased water permeability according to the present invention as described above is frosted or snowed on a road or a roadway, it rapidly thaws it through a pipe through which a high-temperature fluid is moved, The number of ice sheets can be rapidly discharged to the ground through the block, thereby minimizing the time for the ice water to stay on the upper surface of the snow block, There is an effect that it is possible to prevent icing and prevent splashing of water on a snow-melting block by a vehicle or a pedestrian.

In addition, the time taken for the fluid flowing from the outside through the gradient of the upper concrete block, the permeable block and the discharge hole to stay on the automatic pouring concrete block is further minimized, and the heat loss can be minimized.

In addition, it is easy to transfer and install concrete blocks that form a guide or a roadway, and since the block is installed, it is possible to replace or repair the block without replacing the guide and roadway as a whole when breakage or abnormality occurs. And it is possible to reduce the maintenance period and maintenance cost. Also, since one automatic pouring concrete block is also modularized into the upper concrete layer, the lower concrete layer and the water permeable block, It is possible to replace or repair only the relevant module. Since the high-temperature fluid flows through the pipe inserted inside, heat transfer can be performed automatically, so that the snow or ice formed on the road can be automatically removed without any additional apparatus or personnel In the summer, low-temperature fluid flows through the pipeline, It is possible to prevent the temperature from rising to a predetermined temperature or more.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to a method and apparatus for rapidly freezing and discharging a concrete block forming a guideway or a roadway, and discharging the same to the ground, thereby shortening the time required for discharging the ground water to re- (20), a through hole (30), a water permeable block (40), and a lower portion of the waterproof block (40) And a concrete layer (50).

The upper concrete layer 10 forms an upper surface of a road such as a roadway or a sidewalk and receives heat of hot fluid flowing through the piping 20 inserted therein when snow or ice occurs in the winter season, ) This is a structure for melting snow on the upper surface or melting ice. Accordingly, it is preferable that the upper concrete layer 10 is made of a thermally conductive concrete so as not to be easily broken when a person or a vehicle is traveling, and to transmit the heat of the fluid flowing in the pipe 20 to the upper surface quickly.

The upper surface of the upper concrete layer 10 is formed in the upper concrete layer 10 in order to prevent the fluid generated due to snowing or freezing from snowing or thawing or the fluid flowing from the outside into the upper concrete layer 10, It is preferable that a gradient S that gradually decreases in a direction in which the water-permeable block 40 to be described later is combined is formed. In this case, although the angle of the gradient S is exaggerated in order to clarify the features of the present invention, in the actual use, the obstacle does not occur during passage of a person or vehicle, and the fluid flowing on the upper portion of the upper concrete layer 10 So that the gradient S is formed at an angle corresponding to the angle.

The pipe 20 is inserted into the upper concrete layer 10 as shown in FIGS. 1 and 8 to provide a path through which a high-temperature fluid supplied from the heat source 70 can flow, And may be arranged in various forms inside the concrete layer 10. The inlet 25 and the outlet 26 of the pipe 20 through which the fluid flows are preferably formed by bending the upper concrete layer 10 As shown in FIG. 1, the inlet 25 and the outlet 26 of the pipe 20 are exposed to face each other and face each other and face each other. However, And can be configured to be exposed in various forms according to the embodiments.

A plurality of through holes 30 communicating from the upper surface to the lower surface of the upper concrete layer 10 are formed. The through holes 30 are formed in the vertical direction between the pipes 20 arranged over the entire surface of the upper concrete layer 10 as shown in FIGS. 2 and 3, The water permeable block 40 formed is inserted into the through hole 30 so that the thawing water on the upper surface of the upper concrete layer 10 due to the heat of the pipe 20 does not stay on the upper surface for a long time, And is immediately discharged to the ground side through the cast block 40. Accordingly, it is possible to prevent re-icing of the ice water due to the external cold, and also to prevent the water from splashing on the block by the vehicle or the user due to shortening of the staying time of the ice water on the block. . At this time, the through hole 30 is provided to provide a space into which the water-permeable block 40 can be inserted.

At this time, if the gradient S that gradually decreases in the direction in which the water-permeable block 40 is joined on the above-described upper concrete layer 10 is formed, rapid and easy discharge can be achieved.

The lower concrete layer 50 is provided on the lower part of the upper concrete layer 10 in the same area as the upper concrete layer 10 and supports the lower concrete layer 50 to minimize the heat transfer from the pipe 20 to the lower part Is a configuration for maximizing the upward heat flow amount and minimizing the downward heat flow amount with reference to the pipe 20. For this purpose, the lower concrete layer 50 is preferably made of a concrete having a relatively low thermal conductivity as compared with the upper concrete layer 10.

At this time, the upper concrete layer 10 and the lower concrete layer 50 are formed to have the protrusions 12 and the grooves 52 and are coupled to each other so that the upper concrete layer 10 The lower concrete layer 50 is not dislocated, and the bonding strength for maintaining the originally joined position is improved.

On the lower concrete layer 50, a discharge hole 54 communicating with the ground is further formed so as to facilitate discharge of the fluid flowing through the water-permeable block 40 to the ground side. Although the discharge holes 54 are formed on the lower side of the water-permeable block 40 as shown in FIGS. 1 and 3 and are formed in a plurality of holes having a diameter smaller than the thickness of the water-permeable block 40, The diameter of the discharge hole 54 may be larger than or equal to the thickness of the water-permeable block 40.

4 and 5, the discharge hole 54 is formed in the same shape as the cross-sectional area of the water-permeable block 40, and the discharge hole 54 is formed so as to seat the water- And a step groove portion 56 is formed on the upper side.

The structure of the discharge hole 54 minimizes the permeation of the external fluid into the inside of the automatic pouring concrete block through the upper surface of the upper concrete layer 10, the permeable block 40 and the discharge hole 34 in sequence The heat transfer effect of the piping 20 can be maximized.

The inlet 25 and the outlet 26 of the piping 20 of the adjoining and arranged upper concrete layer 10 are configured to be inserted and closely contacted through the connection pipe 60. The connection pipe 60 is connected to the inlet 25 and the outlet 26 as shown in FIG. 7, and may be formed of a synthetic resin material having both rigidity and adhesion, or may be formed of a steel pipe, As shown in Fig.

The water-permeable block 40 may have a protruding and recessed structure between the water-permeable block 40 and the lower concrete layer 50 as in the above-described combined structure of the upper concrete layer 10 and the lower concrete layer 50 So that a firm fixing force can be obtained.

The water-permeable block 40 may be provided in a separate block state, such as an upper concrete layer 10 and a lower concrete layer 50, and may be assembled and formed into a shape on the through hole 30 , And pervious concrete is poured and cured on the surface. 4, the pervious block 40 is formed with a groove 41 for insertion of the pincers on the upper surface thereof so that the separation of the pervious block 40 on the through hole 30 of the upper concrete layer 10 So that it can be easily configured.

In the snow block having the increased water permeability according to the present invention, the area of the guide or roadway to be used is calculated and its size is determined. Referring to FIG. 8, the concrete blocks are disposed in close contact with each other so as to correspond to the area of the roadway or the roadway, and the upper concrete layer 10 and the lower concrete layer 50 are disposed preferentially.

The piping 20 of each concrete block is connected to the supply pipe and the return pipe of the heat source 70 and the permeable block 40 is connected to the through hole 30 on the upper concrete layer 10, Is completed.

In the snow block having increased water permeability according to the present invention, when a snow or ice occurs in the winter season, a high temperature fluid is supplied from the heat source 70 to allow a high temperature fluid to flow to the pipe 20, The high-temperature fluid flows and the generated heat is transferred to the upper concrete layer 10. Since the upper concrete layer 10 is made of a material having relatively high thermal conductivity as compared with the lower concrete layer 50, the heat generated in the pipe 20 maximizes the upward heat flux, minimizes the downward heat flux, Can be maximized.

By automatically dissipating snow or ice formed on the upper concrete layer 10 through the heat transfer of the high-temperature fluid flowing through the pipe 20, it is possible to smoothly pass through the pedestrian or the vehicle while preventing the water from splashing .

At this time, the fluid generated while snow melting or freezing flows flows toward the water-permeable block 40 side along the gradient S of the upper concrete layer 10, and the permeable block 40 provided between the pipes 20, Flows through the discharge hole 54 formed in the lower concrete layer 50 to the outside quickly to minimize the time during which the fluid stays between the concrete blocks, thereby improving the heat transfer efficiency through the pipe 20 It is possible to maximize it.

Conversely, during the summer, when the temperature of the delivery or driveway rises excessively, the low temperature fluid can be passed through the pipe 20 to lower the temperature of the delivery or driveway.
