Description

  The present invention relates to a renewal structure for reusing a final disposal site filled with waste.

  As the final disposal site for waste is constantly in trouble with residents around the private house, a concrete bank 10 is constructed around the remote mountain 11 as shown in FIG. In many cases, a concave space is used. The inner surface of the concave space formed between the bank 10 and the cut mountain 11 is subjected to a water shielding treatment with the water shielding sheet 2 so that the contaminated water does not permeate, and the waste 20 is dumped. When the waste 20 reaches the height at which the bank 10 is located, the upper surface of the waste is covered with the water shielding sheet 2 to perform the water shielding treatment, and finally the soil covering work is performed, tree planting is performed, and the public land is provided. Etc.

  However, due to the rapid industrial development and mass consumption in recent years, the amount of waste has increased dramatically, and this tendency is getting stronger. For this reason, the final disposal sites are becoming scarce year by year, but it is not desirable from the viewpoint of nature protection and disaster prevention from the viewpoint of nature protection and disaster prevention to newly cut down the mountains. For this reason, there is an increasing demand for effective reuse of the used final disposal site, where the waste is now full and soil covering work has been performed.

  Despite these problems, there is currently no prior art for reusing the final disposal site.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to effectively reuse a final disposal site in which waste is landfilled.

In order to solve the above-mentioned problems, the renewal structure of the final disposal site according to the present invention constructs a simple bank on the waste in the vicinity of the existing bank of the final disposal site, and on the inner surface of the simple bank. It is a renewal structure of the final disposal site that has been subjected to water shielding treatment ,
The simple bank constructed on the waste is stacked with a plurality of embankment layers on the lower reaction plate provided on the entire bottom surface of the simple bank with reinforcing materials interposed therebetween, and both ends thereof are connected to the reinforcing material. The upper reaction force plate is provided on the embankment layer and on the entire upper surface of the simple bank, and the upper reaction plate, the embankment layer, and the lower reaction force plate are vertically moved. It is integrated by compressing up and down with a tension material inserted through.

In the renewal structure of the final disposal site according to the present invention, one frame and the other frame that reinforce both sides of the simple bank are connected by a reinforcing material interposed between the embankment layers. Is desirable. And it is desirable to coat the inner surface of the simple bank with a water-impervious sheet and to perform the water-impervious treatment, and it is more preferable to coat with a plurality of water-impervious sheets and apply the water-impervious treatment. Alternatively, any one of a mortar layer, a resin mortar layer, a rubber asphalt layer, and a urethane resin layer may be formed on the inner surface of the simple bank, and a water shielding sheet may be stacked on the inner side to perform a water shielding treatment.

Since the renewal structure of the final disposal site of the present invention constructs a simple bank on the waste inside the existing bank, it is possible to effectively reuse the used final disposal site where the waste has been landfilled. This eliminates the need to cut down a new mountain and secure a site, thus contributing to nature conservation and preventing natural disasters such as landslides. In addition, enormous costs are required to cut the mountains, but the present invention is economical because construction costs are low because only a simple bank is constructed. And since the water impervious treatment is performed on the inner surface of the simple bank, the contaminated water in which the harmful substances in the waste are dissolved does not leak to the outside. In addition, like the simple bank of the present invention, a plurality of embankment layers are stacked on the lower reaction force plate provided on the entire bottom surface of the simple bank with reinforcing materials interposed therebetween, and the reinforcing materials are attached to both side ends. Reinforced with a reinforced frame, the bank can be constructed while preventing the bank from collapsing from the slopes on both sides. Further, an upper reaction force plate is provided on the embankment layer and on the entire top surface of the simple bank, and the upper reaction force plate, the embankment layer, and the lower reaction force plate are vertically compressed by a tension material inserted vertically. When integrated, the embankment layer is tightly tightened to become stronger, and the strength of the simple bank is improved, so that collapse can be prevented. The simple bank constructed by this method has almost no sinking or shrinking of the bank due to aging. There is no distortion in the layers.

  Moreover, if the inner surface of a simple bank is covered with a water shielding sheet, an easy and reliable water shielding treatment can be performed, and leakage of contaminated water from the renewed portion can be prevented.

  Furthermore, if it coat | covers with the water-shielding sheet | seat piled up by multiple sheets, water-shielding will become still more reliable and safety will be improved.

  In addition, by forming any one of mortar layer, resin mortar layer, rubber asphalt layer, urethane resin layer on the inner surface of the simple bank and overlaying the water shielding sheet on the inner side, easy and reliable water shielding treatment can be performed. it can.

  Hereinafter, typical embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to these embodiments.

  1 is a schematic cross-sectional view showing a renewal structure of a final disposal site according to an embodiment of the present invention, FIG. 2 is an enlarged cross-sectional view of a main part of the renewal structure, and FIG. 3 is a frame for reinforcing both side ends of a simple bank. FIG.

  As shown in FIG. 1, the renewal structure of this final disposal site is simplified on the waste 20 in the vicinity of the existing bank 10 when the concave space of the existing final disposal site is filled with the waste 20. The bank 1 is constructed, and the inner side surface of the bank 1 is imbedded by the water shielding sheet 2, and the space above the waste 20 between the simple bank 1 and the cut mountain 11 is added as a new disposal space. In this embodiment, the final disposal site to be renewed is to cover the inner surface of the concave space formed between the existing bank 10 and the cut mountain 11 with one or two water shielding sheets 2 stacked. In this way, the contaminated water is prevented from leaking to the outside and the waste 20 is dumped in this concave space. However, the surrounding space may be surrounded by a bank 10 to form a waste dumping concave space.

  The existing bank 10 is a concrete bank with a trapezoidal or rectangular cross section, and has strength that can sufficiently withstand the pressure even if the waste 20 is piled up in a concave space as shown in FIGS. Yes. The simple bank 1 may be integrally formed inside the existing bank 10, and if formed in this way, the strength and pressure resistance of the simple bank 1 are improved, so that the pressure of the waste is sufficient. Can withstand.

  As shown in FIG. 2, the simple bank 1 has a concrete lower reaction plate 1 a formed close to the inside of the existing bank 10. A plurality of embankment layers are stacked on the lower reaction plate 1a via the reinforcing material 4, and an upper reaction plate 1b made of concrete is placed on the top. A reinforcing frame 3 is embedded in each end of each embankment layer 1e to prevent the slope from collapsing, and is made of a synthetic resin net interposed between each embankment layer 1e and having a high tensile strength. 4, the frame 3 at both ends is connected. And the tension material 1c is penetrated in the up-down direction from the upper reaction force board 1b to each embankment layer 1e and the concrete lower reaction force board 1a. The tension material 1c is made of a PC steel bar or the like, and its lower end is fixed to the lower reaction force plate 1a. By tightening the fastener 1d on the male screw forming portion on the upper end, A simple bank 1 is constructed by vertically compressing and integrating the force plate 1b, each embankment layer 1e, and the lower reaction force plate 1a. When the tension material 1c is compressed in the vertical direction in this way, a force is exerted to push the embankment of each embankment layer 1e laterally, but both side surfaces (slopes) of each embankment layer 1e are reinforced by the frame 3. Therefore, collapse of the embankment can be prevented. When the lower end of the tension material 1c is vertically placed on the concrete when the concrete is cast to form the lower reaction plate 1a as in this embodiment, the workability is improved.

  Although not shown, the tension material 1c may be passed through the lower reaction force plate 1a, and the upper end and the lower end of the tension material 1c may be tightened and compressed by the fastener 1d. In this embodiment, a synthetic resin net is interposed in the embankment layer as the reinforcing material 4, but the reinforcing material is not limited to the synthetic resin net as long as the reinforcing material has a high tensile strength. For example, iron A grid or a wire mesh is also preferably used. The simple bank 1 may be constructed of any material as long as it can be easily constructed and has a high strength. For example, it may be constructed of a concrete block or a lightweight embankment containing foamed polystyrene.

  As shown in FIG. 3, the above-mentioned frame 3 has a horizontal member 3a made of a high-strength welded wire mesh in which thick metal wires 3d are arranged in a grid pattern and welded at each intersection, and inclined from the front end to the rear end. The rising member 3b, which is also formed of a welded wire mesh, is connected and fixed by a connecting member 3c, and a reinforcing member 4 is attached to the rear end of the horizontal member 3a. The material 4 is connected to the frame 3 at the other end.

  As the metal wire used as the vertical and horizontal lines of the horizontal member 3a and the rising member 3b, an iron wire or steel wire having a thickness of about 5 to 8 mm and having a surface subjected to rust prevention treatment is preferably used. Moreover, it is desirable that the interval between the vertical line and the horizontal line is set to about 50 to 100 mm so that sufficient pressure resistance can be obtained.

  The connecting member 3c that connects the upper part of the rising member 3b and the rear part of the horizontal member 3a is also made of the same iron wire or steel wire as described above, and its upper end and lower end are bent into a substantially annular shape, and the rising member 3b and the horizontal member 3a are connected. Are connected so as to have a predetermined slope angle. The frame 3 of this embodiment is convenient because the rising member 3b and the horizontal member 3a can be easily adjusted to an arbitrary angle by the connecting member 3c, but an iron grid or expanded metal bent to match the angle of the slope is used. Of course, it may be used as a legal framework.

  Although the simple bank 1 can be easily constructed, it has high strength and can withstand the pressure of waste, and there is no fear that the slope will collapse even if it rains. There is almost no settlement or contraction on the bank. This simple bank 1 can be constructed after the existing final disposal site is full of waste and has been covered with soil, and it can still be covered by applying water shielding treatment to the lower surface of the simple bank 1. It can also be built on waste that has not been constructed.

  As shown in FIG. 2, the inner slope of the simple bank 1 is subjected to double water shielding treatment with a water shielding sheet 2 made of synthetic resin. One sheet of the water shielding sheet 2 may be used, but it is desirable to cover two sheets in order to more reliably shield the contaminated water from leaking outside. Further, a mortar layer, a resin mortar layer, a rubber asphalt layer, or a urethane resin layer is sprayed on the inner slope of the simple bank 1, and the inside is covered with a synthetic resin water shielding sheet 2 for shielding. It is also desirable to perform water treatment. Thus, even if the water shielding sheet 2 is stacked on the inner slope of the simple bank 1 or a mortar layer is formed, the simple bank 1 is unlikely to cause settlement or shrinkage of the bank over time. There is no worry that the water sheet 2 is displaced from the simple bank 1 and peels off, or the mortar layer is distorted and cracked. Furthermore, a plant may be grown by laying a vegetation sheet on the slope of the outside of the simple bank 1.

  The renewal structure of the final disposal site as described above is economical because it can be easily constructed simply by constructing the simple bank 1 and applying a water shielding treatment to the inner slope of the bank, making it easy to construct and inexpensive to construct. It can be effectively reused at the final disposal site filled with waste.

It is a schematic sectional drawing which shows the renewal structure of the final disposal site which concerns on one Embodiment of this invention. It is a principal part expanded sectional view of the renewal structure. It is a perspective view of the method frame which reinforces the both ends of a simple bank. It is a schematic sectional drawing of the conventional final disposal site.
