KR19990012411U - Landfill Leakage Prevention Structure in Dike Foundations - Google Patents

Abstract

In the present invention, when constructing a dike or a revetment, the filter mat is formed on the sandstone surface to prevent the landfill soil from sinking and collapsing due to the loss of landfill soil between the fine pores of the dike before the sandstone surface of the foundation surface of the embankment is reclaimed with landfill soil. In order to prevent the filter mat from being damaged by the sharp edges of the dead stone surface, to reduce the impact such as the wave force applied to the dike, and to extend the life of the dike, waste tires are interposed flat on the dead stone surface. The present invention is to devise a structure for preventing landfill leakage in foundation mounds of embankment, in which a filter mat is installed on the surface of waste tires and the landfill soil is embedded.

In the present invention, when constructing a levee or a revetment, the ground replacement space at the back of the embankment foundation is generally buried to form a flat ground surface. After laying, it is reclaimed with soil, sandstone, etc., and the landfill is discharged between the fine pores of the dike due to rainwater to prevent the landfill soil from settling and collapse after a long period of time. As it is installed on the surface of the dead stone, there is a problem in that the filter mat of the portion which is treated to the sharp edges of the dead stone surface is broken and the like, and thus the function of the filter is lost.

The present invention fundamentally solves the above-mentioned problems and flatly connects waste tires and tires on the surface of the dead stone so that the filter mats can exhibit the original filter effect, and installs the filter mats on the surface of the waste tires. This prevents damage to the filter mats caused by the corners of the sandstones and allows the tires to absorb and absorb shocks (waves, external shocks, etc.) applied to the banks or lakes, thereby extending the service life of the banks and lakes. Exemplary embodiments will be described in detail with reference to the accompanying drawings.

1 is a cross-sectional view of a dike when the back of a sandstone embankment is filled with general landfill soil. FIG. 1 shows a filter mat (3) on a base embankment (2) on the back of a conventional dike (1). 4) shows that the landfill tire (5) according to the present invention after laying the filter mat (3), and Figure 2 shows the time to install the landfill soil, the embodiment of Figure 1 This is a drawing showing an embodiment in which fine grain (including dredged soil) 4a having a particle size much smaller than that of ordinary landfill soil is buried. FIG. 2 shows a double or multilayer waste tire 5 as necessary. In this case, the filter mat 3 is also interposed between the layers of the waste tire 5 and the waste tire 5a, and the waste tire 5 and the waste tire are made of a predetermined synthetic fiber yarn, or the like. Unite tightly as the binding line (6) of the When laying in layers (when reclaimed with landfill soil), the interior of the waste tire (5) is filled with concrete (7) or gravel (7a), and the space between the waste tire (5) and the waste tire is filled with gravel (7a). When stacking the waste tires 5 in a multi-layer, one layer fills the space between the waste tire 5 and the tires in the same manner as when the landfill is made of ordinary landfill soil, and more than two layers of clay are contained in the waste tire 5a. And concrete (7) is preferably filled with sand or clay in the space between the waste tires (5) to form a waste tire layer. The filter mat (3) is provided on the outermost side of the waste tire layer (3). By embedding the fine sand from the surface, the filter mat laying structure of the present invention is constructed. For reference, as described above, the same effect can be obtained by installing waste tires in the same manner when protecting the support mats laid on the planar soft ground to be buried as another embodiment.

The present invention configured as described above, since the outflow is blocked by the filter mat (3) buried soil sand 4 embedded in the back of the sandstone embankment, the back surface of the embankment is not collapsed collapsed, the wave or other impacts from the outside is applied to the embankment. Even if the waste tire 5 installed in a single layer or multiple layers absorbs shocks, the endurance life of the embankment is extended, and the filter tire 3 is multi-layered between the waste tire layer and each layer. It is a very useful design that saves time and economics by dredging the fine-grained soil (dredging soil) which is settled in front of the dike, and dumping it directly on the back of the dike to be used as landfill soil.
