Description

DRAIN STRUCTURE OF BREAST WALL CONSTRUCTION OF SUMP AREA}

The present invention relates to a backfill drainage structure of a retaining wall structure in a wetland region with high groundwater exposure. More specifically, a half-moon column perforated pipe made of fiber-reinforced plastic composed of several holes in the lower part and the middle part is installed at the rear of the retaining wall structure. In the groundwater exposed area having a structure in which the groundwater flowing into the perforated pipe from the filter material is drained through the half-wall column pipe to the drain wall bottom drain through the half moon column pipe. A retaining wall structure backfill drainage structure.

In general, a retaining wall structure installed in a wetland area with high groundwater exposure is provided with a drainage hole in the retaining wall structure for drainage occurring at a place such as an inclined surface, through which the water generated from the rear of the retaining wall structure is treated. .

In particular, the retaining wall structure is provided with a drain in order to prevent collapse by earth pressure.

1 is a view showing the structure of a conventional retaining wall drainage system, the retaining wall structure 10 is provided with a nonwoven filter aggregate 14 in multiple stages in the vertical rear, the retaining wall structure 10 is a plurality of drain holes (18). ) Is formed at the top, the middle and the bottom.

That is, the retaining wall structure 10 is installed in front of the slope so as not to collapse to the road 30 on the inclined surface such as a mountain slope.

The retaining wall structure installed in the area of the above-described conventional groundwater exposure has a problem in that the soil is leaked through the drain hole due to the construction of a plurality of drain holes in the retaining wall structure, which impairs the aesthetic appearance of the retaining wall. In addition, in the drainage of the retaining wall structure, there was a problem in that a freezing phenomenon occurred on the concrete surface due to water leakage in winter, and thus a defect occurred in a short time.

The present invention is to solve the above problems, the present invention, to smooth the retaining wall backfill drainage in wetland areas with high groundwater exposure, and there is no drain hole in the middle of the retaining wall structure can ensure the most aesthetics, especially in winter The purpose is to provide a backfill drainage structure for retaining wall structures in groundwater exposed areas that has the structure to prevent freezing in winter.

In order to achieve the object described above, the present invention, in the drainage system of the retaining wall structure is installed in the area with high groundwater exposure, in the drainage system of the retaining wall structure, horizontal to the bottom of the structure perpendicular to the retaining wall structure A plurality of drain holes are formed, and the retaining wall structure is provided with a plurality of vandal column pillars vertically to the rear thereof. In the vandal column pillars, three through holes are formed at the top, middle and bottom of the vertical height. The vandal-type column perforated pipe prevents the inflow of soil by maximizing the earthwork by combining the cap of the perforated pipe at the top, and the half-moon filter material is installed at the rear half of the half-wall column perforated pipe of the retaining wall structure. The filter material is inserted into the inside of the polyethylene filter net and the T-shaped part is formed in the middle of the filter material. Retaining wall of the groundwater exposed area, characterized in that the structure is installed integrally, the T-hole perforated tube formed inside the vandal-type filter material in the through-hole of the half-moon column pipe pipe is coupled to the half-moon column pipe pipe to drain the water through the drain hole Provide backfill drainage structures.

Hereinafter, with reference to the accompanying drawings will be described the configuration and operating state of the subject innovation.

Figure 2 is a perspective view of the retaining wall drainage system of the present invention, Figure 3 is a perspective view showing a rear surface of the retaining wall drainage system of the present invention.

The retaining wall structure 50 is provided with a semi-dal filter element 58 horizontally at the top, a middle portion, and a lower end in the vertical rear, and a plurality of semi-dal column pillar perforated pipes 54 perpendicular to the side where the semi-dal filter element 58 is formed. The retaining wall structure 50 is provided with a plurality of drain holes 52 horizontally formed at the bottom of the height direction.

Three through-holes 56 are formed at the top, middle, and bottom of the vandal-type column perforated tube 54 at the vertical height, and the half-moon filter material 58 is formed at the through-hole 56 of the half-moon column perforated tube 54. Are fixed respectively.

In the half-moon-shaped pillar hole tube 54, the hole tube stopper 55 is installed at the top and finishes.

In the vandal filter material 58, the filter material 62 is inserted inside the polyethylene filter network 60, and the T-type perforated pipe 64 is installed in the middle of the filter material 62. The type hole tube 64 is coupled to the half-moon column hole tube 54.

4 is a view illustrating a construction state of the retaining wall drainage system according to the present invention. The first step is to construct the retaining wall structure 50 and install a drain 52 at the bottom of the retaining wall structure 50. .

The second step is a step of compacting the first stage earth and sand after installing the half-moon columnar perforated pipe 54 in the retaining wall structure 50 and installing the half-moon filter material 58.

The third step is a step of compacting the two-stage earth and sand after the half-dal filter material 58 is installed in the half-moon pillar hole tube 54.

The fourth step is a step of compacting the three-stage earth and sand after the half-dal filter material 58 is installed in the half-moon columnar pipe 54.

At this time, the vandal-shaped column hole tube 54 is to solve the problem that the earth and sand is inserted into the half-moon column hole tube 54 when the ground to close the end of the hole pipe plug 55 in the top.

As described above, the retaining wall structure 50 is coupled to the half-moon columnar perforated pipe 54 and the half-moon filter material 58 in the rear to smoothly process the water generated on the slope.

On one side where the retaining wall structure 50 is installed, a road 66 is installed so that water passing through the drain port 52 of the retaining wall structure 50 passes through the half-moon filter material 58 installed behind the retaining wall structure 50. After being drained to the drain hole 52, the soil bleeding does not occur to secure aesthetics and freezing does not occur in winter.

It describes the effect of the configuration and operation of the present invention described above.

The backfill drainage structure of the retaining wall structure of the groundwater exposed area of the present invention has no drainage hole in the middle of the retaining wall structure, thereby ensuring the aesthetics as much as possible and at the same time, it has the effect of smoothly treating the drainage of the wetland area with high groundwater exposure.

The backfill drainage structure of the groundwater exposed area of the present design has the effect of reducing the cost of maintaining and managing the retaining wall structure because no freezing phenomenon occurs at all in winter such as winter because there is no drainage hole.
