Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an apparatus for preventing uplift of an upper-

The present invention relates to an apparatus for preventing uplift of upper and lower troughs and a construction method thereof.

Underground passageways and water and sewerage passages passing under the road (highway) or under the embankment of the railway are made by concrete culvert. Generally, the cross-sectional shape of the culvert is rectangular and has a certain thickness. The concrete culvert is constructed by pouring and curing the concrete on the floor, installing the base concrete, installing the inner formwork and the outer formwork on the base concrete, pouring and curing the concrete on the inner formwork and the outer formwork, .

Fig. 1 is a cross-sectional view of a road in which a concrete culvert is installed, and Fig. 2 is a longitudinal sectional view of a road in which a concrete culvert is installed. As shown in Figs. 1 and 2, a structure in which a concrete culvert 10 is installed on a road in the lateral direction of a road in a furnace A1 of a road, And the packaging layer 20 is packed on the upper surface of the embankment layer with a packaging material such as ascon. The embankment layer is divided into upper and lower zones (A1) and (A2). The clay layer corresponding to the upper surface area of the concrete culvert 10 is referred to as topiere and the escape of less than 3 m in which the breakage frequency of the winter pavement is high is referred to as low toe A. The concrete culvert 10 serves as a passage in the lateral direction of the road .

However, due to the cold waves and heavy snow in winter, moisture penetrates through the packing layer 20 and the embankment layer corresponding to the upper surface area of the concrete culvert 10 and stays on the upper surface of the concrete culvert 10 As the concrete culvert 10 is cooled by cold air while the cold air flows through the concrete culvert 10, the number of residues staying in the filler layer on the upper surface side of the concrete culvert 10 is frozen So that the volume of the embankment layer expands and the package layer 20 rises. As a result, the flatness of the road and the driving comfort are poor, thereby causing a traffic accident. In addition, when relatively unavailable air flows through the concrete culvert 10, the temperature of the concrete culvert 10 rises and the frozen residuum is melted to reduce the volume of the embankment layer on the upper side of the concrete culvert 10, So that the ridge of the second electrode 20 does not fall. If the freezing and thawing of the staying water is repeated, the uplifting of the packaging layer 20 is repeated and cracks are generated in the packaging layer 20.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an apparatus for preventing a freezing and thawing of a clayey soil region (a low-toothed region) corresponding to an upper surface area of a culvert buried in a road, and a construction method thereof.

Another object of the present invention is to provide a simple low toe pile upper package uplifting prevention device which is easy to construct and a construction method thereof.

In order to achieve the object of the present invention, there is provided a culvert; A heat insulating layer located on the upper surface of the culvert and blocking heat transfer; And a waterproof layer positioned on the upper surface of the heat insulating layer and having a waterproof function, wherein the width of the heat insulating layer is larger than the culvert width.

The width of the heat insulating layer is preferably 2.5 to 3.5 times the culvert width.

Preferably, the heat insulating layer has a plate shape in which blocks of EPS (Expandable PolyStrene) are connected to each other.

The thickness of the heat insulating layer is preferably 5 to 15 cm.

The waterproof layer is preferably a vinyl sheet.

The size of the waterproof layer is preferably equal to the size of the heat insulating layer.

The width of the heat insulating layer is preferably 2.5 to 3.5 times the width of the culvert.

Preferably, the insulation layer is constructed by connecting blocks of EPS (Expandable PolyStrene) to each other.

The size of the waterproof layer is preferably equal to the size of the heat insulating layer.

The present invention provides a thermal insulation layer and a waterproof layer on the upper part of the culvert to prevent cold water from being transferred from the culvert to the low-pile fatigue, and to prevent the infiltration of water into the low- Thereby preventing frozen water from being frozen. As a result, it is possible to prevent expansion of the low-tongue in the upper surface area of the culvert and to prevent the packing material from being bulged, thereby maintaining the flatness of the road and the running comfort, and also preventing the cracking of the packaging material.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a low toe pavement upper packaging uplifting prevention device and a construction method thereof according to the present invention will be described with reference to the accompanying drawings.

FIG. 4 is a front sectional view showing an embodiment of a low toe pavement upper packaging uplift prevention apparatus according to the present invention.

As shown in FIG. 4, an embodiment of the low toe trough upper packaging uplifting prevention apparatus according to the present invention includes a culvert 10, a heat insulating layer 30, and a waterproof layer 40.

The culvert 10 is buried in the roof of the road. The culvert 10 is embedded in the lateral direction of the road so as to cross the road. The cross-sectional shape of the culver 10 is rectangular and has a predetermined thickness. The culvert 10 is made of concrete. The culvert 10 becomes a passage across the road. The length corresponding to the lateral length of the road in the culvert 10 is referred to as the length of the culvert 10 and the length in the longitudinal direction of the road is referred to as the width of the culver 10. Backfill material A3 is filled in both widthwise side surfaces of culvert 10 respectively.

The heat insulating layer (30) is located on the upper surface of the culvert (10) to block heat transfer. The heat insulating layer 30 has a uniform thickness and has a set area. The length of one side of the insulation layer 30 corresponds to the length of the culvert 10 and the length of the other side of the insulation layer 30 corresponds to 2.5 to 3.5 times the width of the culvert 10. The side corresponding to the length of the culvert 10 in the heat insulating layer 30 is referred to as a heat insulating layer 30 and the side corresponding to the width of the culvert 10 is referred to as a width. That is, the width of the heat insulating layer 30 is preferably 2.5 to 3.5 times the width of the culvert 10. The central portion in the width direction of the heat insulating layer 30 is brought into contact with the upper surface of the culvert 10. Both portions of the central portion in the width direction of the insulating layer 30 cover the backfilling material A3. The thickness of the heat insulating layer 30 is preferably 5 to 15 cm. As an example of the heat insulating layer 30, the heat insulating layer 30 is preferably made of EPS (Expandable PolyStrene). It is preferable that the heat insulating layer 30 is formed in a plate shape in which blocks of the EPS material are connected to each other.

The waterproof layer 40 is placed in contact with the upper surface of the heat insulating layer 30 to function as a waterproofing member. The size of the waterproof layer 40 is preferably equal to the size of the heat insulating layer 30. As an example of the waterproof layer 40, the waterproof layer 40 is preferably a vinyl sheet. In another example of the waterproofing layer 40, the waterproofing layer 40 may be a waterproof coating film coated on the upper surface of the heat insulating layer 30. [

The embankment layer is formed above the waterproof layer 40 so as to cover the heat insulating layer 30 and the waterproof layer 40. [ The embankment layer area corresponding to the upper surface area of the culvert 10 is referred to as low topography. The embankment layer may be divided into a furnace body (A1) and a hearth (A2) in the vertical direction.

On the upper surface of the embankment layer, a packaging layer 20 packed with a packing material such as ascon is placed.

FIG. 5 is a flowchart illustrating an embodiment of a method for preventing uplift of a low-toe culvert over pavement according to the present invention.

As shown in FIG. 5, in an embodiment of the method for preventing uplift of the low toe culvert upper pavement according to the present invention, the step S1 of burying the culvert 10 in the furnace A1 of the road proceeds first. For example, a space larger than the width of the culvert 10 is provided in a part of the furnace body A1, and the culvert 10 is installed in the space.

After the culvert 10 is installed, a step S2 is performed to backfill each of the outer side surfaces in the width direction of the culvert 10 with a backfill material. The backfill material A3 filled on both sides of the culvert 10 is backfilled so as to be flush with the upper surface of the culvert 10.

After the back filling, a step S3 is carried out to construct the heat insulating layer 30 over the upper surface of the cage 10 and the upper surface of the back filling material A3. It is preferable that the heat insulating layer 30 is formed to have a uniform thickness. The length of one side of the insulation layer 30 corresponds to the length of the culvert 10 and the length of the other side of the insulation layer 30 corresponds to 2.5 to 3.5 times the width of the culvert 10. That is, the width of the heat insulating layer 30 is preferably 2.5 to 3.5 times the width of the culvert 10. The central portion in the widthwise direction of the insulating layer 30 is brought into contact with the upper surface of the culvert 10 and both portions of the central portion in the widthwise direction of the insulating layer 30 cover the backfilling material A3. The thickness of the heat insulating layer 30 is preferably 5 to 15 cm. As an example of the heat insulating layer 30, the heat insulating layer 30 is preferably made of EPS (Expandable PolyStrene). It is preferable that the heat insulating layer 30 is formed in a plate shape in which blocks of the EPS material are connected to each other.

A step S4 of forming a waterproof layer 40 on the upper surface of the heat insulating layer 30 is performed after the heat insulating layer 30 is formed. The waterproof layer 40 is applied to the upper surface of the heat insulating layer 30 so as to be in contact with the upper surface of the heat insulating layer 30. The size of the waterproof layer 40 is preferably equal to the size of the heat insulating layer 30. As an example of the waterproof layer 40, the waterproof layer 40 is preferably a vinyl sheet.

After the waterproof layer 40 is formed, a step S5 of embedding the embankment layer on the upper surface of the waterproof layer 40 proceeds. The embankment layer is filled up with the waterproof layer (40) so as to cover the insulating layer (30) and the waterproof layer (40). The embankment layer area corresponding to the upper surface area of the culvert 10 is referred to as low topography.

The embedding layer is formed and then the packaging layer 20 is wrapped (S6). The packaging layer 20 is packed with a packaging material such as an ascon.

Hereinafter, the operation and effect of the apparatus for preventing uplift of the low toe pavement upper packaging according to the present invention and the construction method thereof will be described.

The vehicle travels along a road provided with the low toe pile upper packing up-and-down preventing device according to the present invention, and the culvert 10 provided on the road functions as a passage. When water (water) penetrates through the packing layer 20 and the embankment layer corresponding to the upper surface area of the concrete culvert 10 due to cold waves and heavy snow in winter, as shown in FIG. 6, The waterproof layer 40 rests on the waterproof layer 40 and does not flow into the upper surface of the heat insulating layer 30 or the culvert 10. In addition, even if the culvert 10 is cooled by the cold air while the cold air flows through the culvert 10, the cold air transmitted to the culvert 10 is blocked by the heat insulating layer 30 and is not transmitted to the staying water, It is possible to prevent freezing of the number of residues in the upper surface area of the culvert 10 due to the cold air transmitted from the indoor unit 10. Particularly, the heat insulating layer 30 and the waterproof layer 40 are sufficiently larger than the top surface area of the culvert 10 so that the cold air of the culvert 10 is transferred to the low-toe side or the water infiltrating into the low- .

As described above, according to the present invention, the heat insulation layer 30 and the waterproof layer 40 are provided on the culvert 10 to prevent cold air from being transmitted to the culvert 10 from the culvert 10, 10 so that only the upper surface region of the culver 10 can be prevented from freezing the infiltrated water into the low-toe. As a result, it is possible to prevent the low-tongue portion of the upper surface area of the culvert 10 from expanding and to prevent the packing layer 20 from being bulged, thereby maintaining the flatness and running comfort of the road, .

Since the culvert 10 is buried and the heat insulating layer 30 and the waterproof layer 40 are formed on the upper surface of the culvert 10, it is easy to construct and shorten the construction time, If the EPS material is applied and the vinyl sheet is applied to the waterproof layer (40), the construction cost can be significantly reduced compared with the existing method in which the entire low toe portion is replaced with the non-cohesive material.
