Description

Slope protection layer molding material of waste landfill and its installation method {DEVICE AND METHOD FOR CONSTRUCTING SLANT PROTECTION LAYER OF LANDFILL}

The present invention relates to a molding material for the inclined surface protection layer of a waste landfill and a method of installing the same. More specifically, a bottom plate, a cover plate, and I made using waste synthetic resins and synthetic resins, which are difficult to process due to the limited use of recycling. Forming material consisting of shape connecting material and gap retaining rod is installed on the slope of waste landfill to promote recycling of resources, and filling materials such as sand are appropriately consumed, which reduces the material cost and increases the amount of waste landfill. And a method for installing the inclined surface protection layer molding material in which the landfill can be freely used.

Today, with the development of social and technological awareness of the environment, the construction and management of waste landfills is increasingly strengthened.

Waste landfill and leachate collection and drainage facilities are the most important of the facilities, and various standards for these facilities are strictly applied.

The standard specifies that a clay mineral order layer or clay composite layer (ventite mat) be installed on the inclined surface, a 2 mm thick HDPE sheet on top, and a protective layer made of artificial synthetic drainage layer and sand with a thickness of 30 cm or more. .

Here, the functions of the protective soil such as artificial synthetic drainage layer and sand, which are built on the HDPE sheet, are as follows.

The artificial synthetic drainage layer is planned because the leachate drainage layer consisting of gravel, sand, etc. cannot be installed on the inclined slope, and it is used as a function of collecting and draining the leachate. This facility is installed when the landfill is constructed.

In addition, protection certificates using materials such as sand are constructed at the time of landfill operation after constructing the landfill site, and are installed on top of the water curtain to collect and drain the leachate, and damage of the water curtain by landfills, etc. Prevents and has a gas exhaust function.

Although these facilities are essential in landfills, construction is somewhat possible in areas with gentle slopes, but most of them are difficult to install and even very difficult to maintain.

A protective layer using materials such as sand is almost impossible to install on top of a steep and slippery HDPE sheet, and when installed without auxiliary facilities, a large amount of material is consumed, which is difficult to construct, and thus, most landfill sites do not use it. It is either neglected or inadequately constructed.

In some landfills, there is a construction method that connects pet tires. However, in this case, additional geotechnical fibers are required between the barrier layer and the pet tire, and in case of laying sand, the sand is filled by erosion. The material is lost to the bottom, and the waste tire connecting string must be fixed at the top. The fastening part is excessively large, and is vulnerable even before the landfill is disposed and becomes more vulnerable after landfill.

Specifically, as shown in FIG. 1, when sand 30 or more, which is a criterion for laying sand for protection of the landfill slope 300 of the waste management method, is laid, the sand 100 is laid in a funnel shape having a shape of a subsoil. ) Only by laminating landfills in order to meet the relevant legislation, so increasing the amount of sand and reducing the amount of landfills leads to enormous economic losses.

The slower the slope of the existing landfill is, the larger the volume of sand must be filled. In fact, the waste must be buried in the middle, resulting in economic losses. Because garbage can not be put in, but this place must be filled with sand, including the cost of purchasing sand will cause huge economic losses.

In addition, the close contact between the waste tire and the lower order layer layer is difficult to lose the filling material such as sand occurs in this portion, there is a difficulty in the connection of the waste tire and the double air filling during construction.

In addition, in terms of economics, there is a problem in that the amount of waste landfill is reduced by an excessive amount of waste material and an excessive amount of material such as an anchoring facility for fixing the membrane and artificial synthetic drainage layer and sand.

In addition, while the use of synthetic resin materials used for various purposes is increased, the method of reusing waste synthetic resin materials is relatively poor, which makes it difficult to process the waste synthetic resin materials.

The object of the present invention devised in view of the above-mentioned conventional problems is to easily install a molding material with a uniform thickness on the slope of a waste landfill and to prevent damage and damage due to the insulator membrane caused by insufficient protection, and to prevent piercing and tearing due to the filling of the waste layer. In case of installing sand layer on the top of the liner, it maintains the proper cross section from erosion and so on. It is achieved by the inclined surface protection layer molding material of the landfill and the method of installing the same, which prevents the damage of the water curtain by the damage, the excessive anchoring of the film or other materials when landfill.

An object of the present invention is to fill a space in the mold of the molding frame consisting of a space between the bottom plate and the cover plate spaced apart to form a space, and the space between the bottom plate and the cover plate to adjust the spacing. It is achieved by the inclined surface protective layer molding material of the landfill.

In addition, the waste is made by filling the filling material into the space of the molding frame consisting of a space between the bottom plate and the cover plate a predetermined interval to form a space between the bottom plate and the cover plate to adjust the spacing between the bottom plate and the cover plate. It is achieved by a method of installing the inclined surface protection layer molding material of a waste landfill site in which one plate of the inclined surface protection layer molding material of a landfill is in close contact with the inclined surface and then laminated and constructed.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 3a is a perspective view showing the structure of the inclined surface protection layer molding frame of the present invention and Figure 3b is a cross-sectional view showing the structure of the molding material filled with a filling material in the molding frame inclined surface protection layer molding material (1) Is provided with a discharge hole (7) for discharging the leachate and gas, and spaced apart a predetermined interval to form a space (4) between the bottom plate 2 and the cover plate 3 formed in a flat, the bottom plate (2) And a filler are filled in the space 4 of the molding die 1a in which the gap retaining rod 5 is provided between the cover plate 3 and the cover plate 3.

The gap retaining rod 5 may be provided with a plurality of gap retaining rods in the form of rods, squares, etc. to fix the bottom plate 2 and the cover plate 3 so as not to flow. It is also possible to use a structure such as an antenna or a conventional structure by a spring, a ball and a fixing groove so that the space 4 between the 2 and the cover plate 3 can be adjusted.

On the other hand, as the filler filled in the space 4 is used sand, gravel, crushed stone and as shown in Figure 4a attached to the groove 8 and the concave-convex portion 9 to facilitate the coupling of the molding material as shown in Figure 4a. Each formed of at least one or more may be used. As shown in FIG. 4B, when the molding die 1a is laminated / planared, the I beam-shaped connecting member 10 is inserted between the adjacent molding dies 1a. Planar construction can be performed.

In the drawings, reference numeral S denotes an inclined surface of a landfill.

As shown in FIG. 2, the inclined surface protection molding member 1 having the above structure includes a bottom plate constituting a molding frame 1a of synthetic resin or waste synthetic resin material on the inclined surface S of a landfill having a predetermined inclination angle ( 2) and the cover plate (3) is in close contact with the inclined surface (S), the filling material 6 is filled in the space (4) and then the molding frame without filling the filler (6) in the space (4) After laminating (1a), the method of filling the filler 6 into the space 4 again is repeated several times so as to have a predetermined height.

Meanwhile, as shown in FIG. 3, the bottom plate 2 and the cover plate prevent the flow of the forming mold 1a, which is a quadrangle when the molding material 1 is laminated / planned, and is easy to install. (3) is provided with a molding frame in which the grooves 8 are formed, and the molding frame adjacent to this is fitted with the grooves 8 in which the uneven portions 9 are formed.

Meanwhile, as shown in FIG. 4B, a connecting member 10 having an I beam shape is inserted between the molding member 1 and the molding member 1 which are connected at the time of lamination / planar construction and connected in a lamination and planar manner. The bottom plate 2 and the cover of the molding member 1 installed between the adjacent molding member 1 and the molding member 1 when installed on the inclined surface S having a curve while preventing damage due to the load during construction The plate 3 is placed inside the connecting member 10 having an I beam shape, but is installed to be widened within the connecting member 10 so as not to deviate from the center plate of the connecting member 10 so as to be curved like a curve. Ash and leachate and gas are drained to the discharge hole (7).

The sloped protective layer molding material and installation method of the waste landfill site of the present invention, which is composed of such a structure, has a limited use for recycling, and thus is difficult to process, such as waste vinyl, waste-PE, waste-PET, waste synthetic resin, and synthetic resin. Forming material consisting of plate, cover plate, I-shaped connecting material and gap retaining rod is installed on the slope of waste landfill to promote the recycling of resources, and appropriate filling material such as sand is required to reduce material cost and filling material such as sand. By appropriately reducing the material cost and increasing the amount of landfills, various filling materials can be freely used.

On the other hand, since the upper and lower parts are structured, there is no problem of erosion, so that they can form a uniform interval and a homogeneous layer permanently. Various facilities can be installed. Since there are no obstacles between moldings, the leachate collection pipe, leachate drainage pipe, landfill gas exclusion pipe, etc. can be installed freely, so the application and flexibility of the facility is great.

In addition, it is possible to secure a homogeneous layer, which not only functions as a protective layer, but also has a function of collecting leachate and a gas drainage layer that can exclude landfill gas. prevent.

The upper and lower structures and the filler block solar light so that solar heat is not directly transmitted to the insulation film, and the adhesion between the insulation film and the underlying material is increased, thereby increasing the frictional force, thereby preventing the drooping to the bottom due to thermal expansion.

In winter, when the clay order layer is freeze-thawed, the coefficient of permeability increases sharply, and the order layer itself is peeled off. When the mold and the appropriate filler are selected, the freezing phenomenon can be minimized.

In case of embedding the protective layer such as sand and the waste on the water curtain, excessive water curtain fixing facilities are needed due to the excessive frictional force on the slope, but this facility can minimize the water curtain fixing facilities by completely separating the waste and water facilities.

By filling material such as sand between the two thick structures and the structure at the upper part of the facility, it prevents damage caused by foreign substances and rats during the maintenance until the landfill is filled up, and occurs a lot when the waste is buried. It can prevent damage to the curtains caused by heavy equipment. Therefore, when using the present invention there is an effect such as not needing a separate protective facility.
