The holding unit 100 includes a first housing 110 for fixing the waterproof mat 200 and a second housing 120 for fixing the geotextile mat 300.

The first housing 110 includes a first flange 111 formed with an insertion hole 114 into which the waterproof mat 200 is inserted and a first flange 111 having a first body portion 112 inserted into the perforation 3 of the bank 1 ).

The first flange portion 111 extends outward along the circumference at the top of the cylindrical first body portion 112. The outer surface of the first flange portion 111 is formed with an insertion hole 114 into which the waterproof mat 200 is inserted. The insertion hole 114 is formed along the circumference of the first flange portion 111.

An extension groove 115 is formed in an inner side of the first insertion hole 114, that is, in the vicinity of the center of the first housing 110, in which the inner space of the hole extends. For example, the extension groove 115 may be provided in a tube shape.

The first body part 112 is formed with a first hollow part 113 passing through the inside of the first body part 112 in a vertical direction.

An engaging groove 116 into which the second housing 120 is inserted is inserted into the upper portion of the first body portion 112. A threaded portion 117 may be formed on the inner side of the coupling groove 116.

The first housing 110 and the second housing 120 may be coupled by threaded joints 117 and 124.

Next, a structure in which the waterproof mat 200 is fixed to the holding unit 100 will be described with reference to FIG. 3 is a cross-sectional view showing a state in which a strainer 10 is joined to a strut unit 100. Fig.

The waterproof mat (200) has a filling space (210) in which a fluid can be injected and discharged. For example, the waterproof mat 200 includes an upper surface and a lower surface, and the upper surface and the lower surface are continuously connected to form a filling space 210 therein.

Although not shown in the drawing, the filling space 210 is connected to an inflow pipe (not shown) connected to a tank (not shown) in which fluid is stored, and the infusion and discharge of the fluid are controlled .

The fluid to be filled in the filling space 210 may be air or water. When the fluid is injected into the filling space 210, the volume of the waterproof mat 200 becomes large, and the distance between the upper surface and the lower surface increases. When the fluid escapes into the filling space 210, the volume of the waterproof mat 200 decreases and the space between the upper surface and the lower surface decreases.

The waterproof mat (200) is formed with a first through hole (220) through which the holding unit (100) passes. The inner diameter of the first through hole 220 corresponds to the depth of the insertion hole 114 formed in the first flange portion 111.

The waterproof mat 200 is inserted into the insertion hole 114 of the first housing 110 without filling the filling space 210 with the fluid. At this time, since the waterproof mat 200 is thin and flexible, insertion into the insertion hole 114 is easy.

The filling space 210 is filled with the fluid after the waterproof mat 200 is inserted into the insertion hole 114. The waterproof mat 200 is inflated and filled in the insertion hole 114.

Particularly, the waterproof mat 200 is also filled in the inside of the expansion groove 115. The waterproof mat 200 accommodated in the extension groove 115 functions as a latching portion for preventing the waterproof mat 200 from being separated from the first housing 110 by an external force. Shear stress acts on the waterproof mat 200 due to the load of the vegetation block 20 and the flow of the river described above and the waterproof mat 200 can be separated from the holding unit 100 by the shear stress. However, the waterproof mat 200 filling the expansion groove 115 may be caught in the expansion groove 115 to prevent it from being separated.

Hereinafter, a method of installing the awnic film unit 10 will be described.

First, the first housing 110 of the holding unit 100 is engaged with the perforations 3 of the bank 1. At this time, the first housing 110 may be press-fitted or may be fixed by injecting a small amount of mortar into the first hollow portion 113. It should be noted, however, that the mortar does not flow over the first hollow portion 113.

After fixing the first housing 110, the waterproof mat 200 is fixed. The method of fixing the waterproof mat 200 has been described above.

After the waterproof mat 200 is fixed, the geared fiber mat 300 is placed on the first housing 110. At this time, the second through hole 310 of the geoscientific fiber mat 300 and the center of the holding unit 100 are made to correspond to each other.

The second housing 120 is then coupled to the first housing 110. The gap between the first flange portion 111 and the second flange portion 121 is reduced while the second housing 120 is engaged and the geoscientific fiber mat 300 is crimped and fixed.

After the geosynthetics mat 300 is fixed, mortar is injected into the second hollow part 123. The mortar integrates the bank 1 and the holding unit 100 while being filled in the perforations 30, the first hollow portion 113 and the second hollow portion 123.

The filling space 210 of the waterproof mat 200 is filled with the fluid before fixing the geotextile mat 300. The waterproof mat 200 may be provided after the geotextile mat 300 is installed Can be buffered.

That is, the waterproof mat 200 is inserted into the insertion hole 114 of the first flange portion 111, and a geosynthetic fiber mat 300 is inserted between the first flange portion 111 and the second flange portion 121 After fixing, the wire 17a can be fastened to the fixed pile 19. [ At this time, a hook or the like for fixing the wire 17a may be provided on the upper portion of the holding unit 100. [

The filling space 210 of the waterproof mat 200 can be filled with the fluid after one end of the wire 17a is fixed to the holding unit 100 and the other end is fixed to the fixed pile 19. [

On the other hand, the waterproof mat 200 can perform not only the waterproof function of the bank 1 but also the insulating function of the bank 1. [ Hot water or hot air may be injected into the filling space 210 to prevent the stream from freezing in the mid-winter. As the temperature of the filling space 210 rises, the temperature of the stream rises due to the heat transfer of the deposition film 10. Through this process, it is possible to prevent rivers from freezing in the middle of winter.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be apparent to those skilled in the art that changes or modifications may fall within the scope of the appended claims.
