JPH04202038A - Production of concrete block applying bag for waste attached with vacuum evacuation pipe - Google Patents

Abstract

PURPOSE:To obtain a block of a hexahedron which is free from secondary pollution by packing waste mixed with cement, lime, resins, etc., into an air bag made of an insoluble and invariable material provided with a vacuum evacuation pipe and evacuating the inside of the bag, then enclosing the outer periphery with an expanded metal net and solidifying the waste by reinforced special concrete. CONSTITUTION:The air bag 3 is produced by using the material which is permanently insoluble and invariable in properties. The vacuum evacuation pipe and gas removing passage are installed to the bag 3. On the other hand, the waste 2 is mixed with the cement, lime, resins, etc., so as not to generate the secondary pollution and the mixture is packed into the bag 3. The bag is hermetically closed and the gas is removed therefrom with the vacuum evacuation pipe to attain the vacuum state. Further, the outer periphery of the bag 3 is enclosed by the expanded metal net 1 to form the hexahedron. The reinforced special concrete 4 is poured to the outer periphery to produce the concrete block. This block does not generate the secondary pollution and is adequately used for civil engineering and construction, ocean development, etc.

Description

[Detailed description of the invention] Industrial application field The present invention is applicable to non-combustible garbage and other wastes generated from ordinary households.
Various types of industrial waste generated from factory workplaces are packed into bags and put through a compression process to create a completely sealed state.The gas is removed and the vacuum is maintained to prevent secondary pollution.In order to prevent secondary pollution, the products are molded into strong concrete blocks. It can be used for development and regional development.

BACKGROUND OF THE INVENTION At present, conventional methods for final disposal of waste include inland disposal and ocean disposal, and large-scale landfill dumping has been carried out, but the trend is that these are far more economical. This is replacing landfill sites located inland, in mountain valleys and depressions, and sites using excavated earth.

Problems to be Solved by the Invention However, there are many problems with these current methods, and there are concerns about securing land for disposal and contamination of groundwater, soil, and public water bodies by sewage gushing out from the disposal site. Ru.

Therefore, even if land is secured, a final disposal site cannot be constructed unless the pollution problem is resolved. Therefore, the final disposal site must have a water-tight structure that completely separates groundwater and wastewater. The structure must be such that the leachate is collected in a wastewater tank.

After covering the entire surface of managed disposal sites, waste treatment, storage areas, etc., which are technically said to have low secondary pollution, waste is piled up in two sections for disposal. Because of the necessity, the construction cost is huge, and the land owner has to cover the land for disposal, and it will last for at least 30 years.''
The current situation is that post-closure management must be carried out.

Therefore, the purpose of the present invention is to prevent secondary pollution by forming a tare bag in which all the above-mentioned waste is completely sealed and packaged into a strong special concrete pro-liquid. It is something to be used and utilized.

Means for solving the problem, that is, the present invention is a tare bag with a gas release pipe passage made in advance of insoluble and unalterable material, which can be folded and glued at the top, is sufficiently filled with waste, and is pressurized by a compressor to remove moisture. Remove and pack. However, in this case, the outer periphery is made of expander wire mesh,
Protected by mold etc.

Furthermore, the outer hexahedron is covered with strong special concrete and dried to a 0.7-peel surface, so that it can be used as a complete product without any damage due to secondary pollution.

Function: The concrete block constructed in this manner does not generate secondary pollution even if it is dumped at an inland disposal site, an ocean disposal site, or a mountain valley disposal site.

In particular, it is used to prevent landslides from flowing out to prevent wind and flood damage.
It can be used in a wide variety of ways, including general roads damaged by waves on corner banks, and the composition of slopes on river embankments.

Embodiment Next, the structure of an embodiment of the present invention will be explained with reference to the drawings. Drawing Figure 1 shows a hexahedral tare bag made of insoluble and immutable material, but the top surface is open to seal it after filling the waste. ■A gas venting pipe is attached. After that, the bag is placed in the expander wire mesh box shown in Fig. 3, and after the waste is pressurized with a press to increase its density, the top of the bag is folded and the part marked with ■ is sealed and glued. After that, connect the vacuum pump from the gas vent to remove the gas. In this way, the gas is completely removed and sealed.

During this time, the work is carried out using holding fittings and molds, and concrete 1 to 1 is poured around the outer periphery and dried to form a complete concrete block.
