1 is a cross-sectional view showing a concrete box for preventing slopes of freezing of the present invention, Figure 2 is a cross-sectional view showing a portion of the concrete box for preventing slopes of freezing, Figure 3 is a front view showing the concrete box for preventing the slopes of freezing.

1 and 2, the concrete box for preventing slope slope of the present invention is largely composed of an induction drain pipe 110, a concrete insulating cover 200, and the front concrete portion 400.

The concrete box is installed on the inclined surface 1 to form a predetermined slope.

The induction drain pipe 100 has a predetermined length and is formed of stainless material to have corrosion resistance.

The induction drainage pipe 100 is disposed on the outer surface portion of the inclined surface 1. Therefore, the induction drainage pipe 100 is disposed to form a predetermined gradient on the slope 1.

The outer periphery of the induction drainage pipe 100 is formed with a heat insulating layer 110 of a predetermined thickness.

The thermal insulation layer 110 is preferably a thermal insulation blanket such as a cover.

The thickness of the thermal insulation layer 110 is determined in proportion to the number of turns of the thermal insulation blanket wound around the outer circumference of the induction drainage pipe 100.

In addition, the number of windings of the thermal insulation blanket is varied according to the winter average temperature at the slope 1. For example, the number of windings of the insulation blanket may increase as the average temperature of the winter falls.

The concrete insulating cover 200 covers to surround the outer periphery of the induction drain pipe 100. The concrete insulation cover 200 is formed of a concrete structure of a predetermined thickness.

Therefore, the concrete thermal insulation cover 200 effectively surrounds the induction drainage pipe 100 having the insulation layer 110 to prevent the induction drainage pipe 100 from dropping below a predetermined temperature.

The outer periphery of the concrete insulation cover 200 is provided with a thermal insulating material 300 of a predetermined thickness. The heat insulating material 300 is preferably made of a thickness of 50mm.

Of course, the thermal insulation material 300 may be installed to form a multi-layer.

When the thermal insulation insulating material 300 forms a multilayer, it corresponds to a case where the average winter temperature around the slope is less than or equal to a predetermined level.

In addition, when the insulating heat insulating material 300 is formed in a multi-layer, the boundary between the insulating heat insulating material 300 is preferably bonded to each other uneven.

Due to the concave-convex coupling, the contact area between the heat insulators 300 may be increased, thereby increasing the heat transfer efficiency.

The front concrete portion 400 is formed in a box shape.

The front concrete part 400 is formed by pouring concrete so as to cover the thermal insulation material 300.

A plurality of shear keys 500 are installed on the rear portion of the front concrete portion 400 as shown in FIG.

A part of each shear key 500 is fixedly installed on the rear part of the front concrete part 400, and the other part of the shear key 500 is inserted and fixed to the inclined surface (1).

Each shear key 500 is formed of a fixed key 510 having a predetermined length and an insertion key 520 bent from an end of the fixed key 510.

The fixing key 510 is fixed in the rear portion of the front concrete portion 400 in a direction parallel to the rear portion.

The insertion key 520 protrudes from the rear portion of the front concrete portion 400 by a predetermined length. The insertion key 520 is inserted into and fixed to the inclined surface 1.

The plurality of shear keys 500 are installed at regular intervals along the rear edge of the front concrete portion 400.

In addition, as shown in FIG. 5, the length of the insertion key 520 in the plurality of front end keys 500 is gradually increased along the upper side from the lower side of the slope 1.

Accordingly, the front concrete portion 400 and the slope 1 may be integral with each other.

Meanwhile, referring to FIGS. 1 and 3, the upper end of the induction drain pipe 100 mentioned above is disposed in the water region a formed on the slope 1.

A horizontal drain pipe 21 is installed in the water region a.

The horizontal drain pipe 21 is inserted into the water region a of the slope 1. The horizontal drain pipe 21 is installed by forming a predetermined gradient in the water region (a).

An end portion of the horizontal drain pipe 21 is exposed outside the water region a.

An end portion of the horizontal drain pipe 21 exposed to the outside of the water region a is connected to the upper end of the induction drain pipe 100 through the elbow 30.

On the other hand, when a plurality of horizontal drain pipe 21 is installed in the water region (a), and the level of the horizontal drain pipe 21 is positioned differently, each induction drain pipe 100 has a different length to form each horizontal drain pipe ( 21) is connected to the end.

Therefore, the level of each of the induction drainage pipe 100 is arranged differently, and are arranged side by side along each other up and down.

The embodiment according to the present invention can prevent the formation of frost on the slopes around the winter road, and select the area where the frosts occur on the slopes to locally prevent frost.

Embodiments according to the present invention are capable of in situ casting in the freezing area at the slope.

Next, the construction method of the inclined surface freezing prevention concrete box comprised as mentioned above is demonstrated.

First stage

Referring to FIGS. 1 and 3, the water region a is set on the slope 1.

The slope 1 is a terrain that forms a predetermined slope along the upper side from the side of the road (1).

The water region a in the inclined surface 1 is a region where the effluent water is generated and taken out to the outside.

2nd step

In the first step, the horizontal drain pipe 21 is installed in the set water region a.

First, the inclination of the line in which the horizontal drain pipe 21 is installed in the water region a is set.

A horizontal drainage hole 20 through which the horizontal drainage pipe 21 may be installed is drilled in the water region a along the line.

After the horizontal drain hole 20 is drilled, a horizontal drain pipe 21 is inserted into the drilled horizontal drain hole 20.

Therefore, it is provided in the water area | region a in the state which makes the constant gradient of the said horizontal drain pipe 21.

Here, the horizontal drain pipe 21 uses a stainless steel pipe. The horizontal drain pipe 21 may have corrosion resistance.

Since the horizontal drain pipe 21 makes a constant gradient in the water region a, the water can be easily flowed along the gradient of the horizontal drain pipe 21.

The gradient of the horizontal drain pipe 21 is preferably set to be inclined downward along the slope (1) side.

One end of the horizontal drain pipe 21 is partially exposed to the outside of the water region a, and the other end is inserted into the horizontal drain hole 20 formed inside the slope 1 including the water region a.

Then, the elbow 30 is installed at one end of the horizontal drain pipe 21.

The elbow 30 is a member connected to the induction drain pipe 100 to be described later.

3rd step

One end of the horizontal drain pipe 21 is connected to the induction drain pipe 100.

In particular, the upper end of the induction drain pipe 100 is connected to the elbow 300 installed at one end of the horizontal drain pipe (21). Accordingly, the horizontal drain pipe 21 and the induction drain pipe 100 form a flow path through which water flows.

The induction drain pipe 100 may be disposed to be inclined along the slope 1.

The lower end portion of the induction drainage pipe 100 is exposed to the drainage flow path part 40 installed on the road 1 variable. The drain flow path part 40 guides the water to drain.

4th step

Surrounding the induction drainage pipe 100 to form a multi-layered thermal insulation layer 110 is provided with a front concrete portion 400 to be integral with the slope (1).

First, the insulating layer 110 is formed on the outer circumference of the induction drainage pipe 100.

The insulating layer 110 may be formed to surround the outer circumference of the induction drain pipe blanket insulation.

The heat insulating layer 110 may be formed to have a predetermined thickness according to the winter average temperature around the slope 1.

That is, when the winter temperature around the inclined surface 1 reaches a predetermined value or less, the insulation blanket may be wrapped around the outer circumference of the induction drainage pipe 100 several times, thereby making the thickness of the insulation layer 110 thicker.

Therefore, the water flowing in the induction drainage pipe 100 may be warmed by the thermal insulation layer 110.

In addition, although not shown in the drawings, an adhesive may be further applied between the outer peripheral surface of the induction drain pipe 100 and the insulating blanket.

By further applying the adhesive, it is possible to prevent the insulation layer 110 from twisting around the outer circumference of the induction drainage pipe 100.

Subsequently, the induction drain pipe 100 provided with the insulation layer 110 is covered using the concrete insulation cover 200.

At this time, the inner surface of the thermal insulation cover 200 may be in physical contact with the thermal insulation layer 110.

The thickness of the concrete insulation cover 200 may also be the same as the thickness determination method of the insulation layer 110.

That is, when the temperature is below a certain level, it is possible to use a thicker thickness of the insulating cover 200.

The thermal insulation material 300 is installed around the thermal insulation cover 200.

The thermal insulation material 300 can effectively prevent the external cold air is transferred to the thermal insulation cover 200 and the induction drain pipe 100.

The heat insulating material 300 may be formed in a multilayer.

Prepare a plurality of the heat insulating material 300, so that each of the heat insulating material 300 overlap each other to form a layer.

In this case, the insulating insulation materials 300 form a boundary layered with each other.

In the present invention may be coupled to each other uneven at the boundary of the thermal insulation insulating material (300).

As described above, the insulating thermal insulation materials 300 may be unevenly coupled to each other, thereby effectively preventing heat transfer loss between the thermal insulation materials 300.

Subsequently, after installing the thermal insulation materials 300 as described above, the concrete is poured to surround the thermal insulation material 300 to form the front concrete part 400.

The front concrete portion 400 is formed to be inclined along the slope of the slope 1 as a whole.

When the front concrete part 400 is formed as described above, the concrete box on which the front concrete part 400 is formed is installed on the slope.

At this time, as shown in Figure 4, a plurality of shear keys 500 are installed in the rear portion of the front concrete portion 400.

The plurality of shear keys 500 are installed to form a predetermined interval on the rear edge of the front concrete portion 400.

In more detail with respect to the shear key 500, the shear key 500 is a member for fixing the concrete box on the slope.

The front end key 500 is composed of a fixing key 510 and an insertion key 520.

The fixing key 510 is a part installed inside the rear part of the front concrete part 400.

The insertion key 520 is a member that is bent from an end of the fixing key 510. The insertion key is a member protruding to the outside from the rear portion of the front concrete portion 400.

The insertion part 520 has a predetermined length, and is a member inserted into the inclined surface 1.

Accordingly, the front concrete portion 400 can be fixed to be integral with the slope 1.

In addition, as shown in FIG. 5, in the present invention, the length of the insertion key 520 may be gradually increased from the lower side of the inclined surface 1 along the upper side.

On the other hand, when the number of extraction portions in the water region a is formed in plural and the number of horizontal drain holes 20 is formed, the level of the horizontal drain holes 20 formed in the plurality is measured.

Then, a plurality of the induction drain pipe 100 is prepared.

The plurality of induction drain pipes 100 prepared in parallel are connected to ends of the horizontal drain holes 20 in parallel with each other.

Embodiments according to the present invention can prevent the formation of freezing on the slopes around the winter road.

The embodiment according to the present invention can prevent the formation of freezing areas on the road by preventing freezing on the inclined surface even if the water becomes water on the inclined surface.

In addition, the present invention can select the area where the freezing occurs on the inclined surface to locally prevent freezing.

In addition, embodiments according to the present invention are capable of in situ casting in the freezing area on the slope.
