Description

Vibrated and rolled reinforced concrete pipes that have waterproof, corrosion resistance, quality of water catharsis and quality of water decomposition prevention function}

The present invention provides waterproofness and anticorrosion by lining the surface of the VR tube in contact with various wastewater, domestic sewage and rainwater or running water with chemical resin, and forms a ceramic tint (foaming layer) on the lining surface so that microorganisms can be inhabited. It is to provide a VR tube that eliminates the risk of water leakage and means for preventing corruption of water resources or treating wastewater by creating anti-bacterial and antifungal properties.

VR pipes that come into contact with various wastewater, domestic sewage and rainwater or running water are rapidly corroded by wastewater and microorganisms passing through the pipe, and lack of waterproofness, which is emerging as a major cause of damage to sewage pipes. To prevent corrosion by microorganisms or to use it for wastewater, and due to the problems of concrete materials, expensive resin concrete tubes made of VR tubes by mixing aggregates and fine powders with chemical resins have appeared, and PE pipes , PVC pipe and glass fiber composite resin pipe are used as sewage pipes.

Generally, lining coating with epoxy paint is used to prevent corrosion of concrete surface. However, simple lining coating loses the characteristics of painting in a short time (which should be accompanied by periodic repainting). It is difficult to apply to VR tube,

At present, the approach related to water purification and corruption prevention by VR pipes is the situation where waterproofing and method of VR pipes are emerging as the whole problem.

Porous carriers made of ceramics, which provide a habitat for microorganisms, are used in aeration tanks or anaerobic tanks of wastewater treatment facilities for treating wastewater by biological treatment methods, or processed into ceramic ball shapes, and each ceramic ball has a net shape. The wastewater is treated by installing it on the side of the river or on the floor by fastening it.

The method of attaching antimicrobial and antifungal properties or wastewater treatment means by microorganisms to the surface of the VR tube provided by the present invention is difficult unless there is a special means for adhesion to foreign substances due to the characteristics of concrete, Is lowered and ineffective, and it is recognized as an ideal wastewater treatment method that can not be adopted by promoting corrosion of the surface of the VR tube,

Water quality (BOD, COD, microbial organisms) is deteriorating through a closed sewage pipe by various microorganisms inhabiting the VR pipe forming the sewage pipe.

Therefore, the present invention is intended for microbial habitats that can be lined with chemical resins of VR tubes in contact with various wastewater, domestic sewage and rainwater or running water, to provide complete waterproofing and anticorrosive properties, and to live by depositing microorganisms on the lining surface for a long time. Forming a foamed porous ceramics lining layer (microbial habitat carrier or ceramic carrier) or forming a bioceramic foam layer containing an antimicrobial material,

First, by forming a ceramic carrier on the surface of the VR tube to create a habitat environment for microorganisms to inhabit or to form an antimicrobial and anti-mildew foam lining coating layer, to provide anticorrosion and waterproof function, as well as to prevent corruption or contact of the contacting water resources Its purpose is to provide a VR tube for water treatment of wastewater,

Second, the purpose is to provide a VR tube with a long life, so that the chemical resin lined on the surface of the VR tube does not peel off during the life of the concrete structure or function degradation related to complete waterproofness and anticorrosion.

The lining method and the lining structure of the concrete surface to realize the present invention is the Korean Patent Application No. 10-2005-0035919 (applied by the inventors of the present invention) And method for manufacturing lining material), Korean Patent Application No. 10-2005-0030299 (Forming for lining concrete surface and forming method of concrete structure and processing of lining of concrete surface using the formwork) and Korean Patent Application No. According to No. 10-2005-0035898 (composition for lining reinforced concrete molded structures and lining construction method using the composition),

Surface treatment of lining the surface of the VR tube with a thermosetting chemical resin, as shown in the embodiment shown in Figure 1 for the waterproof and anticorrosive treatment of the VR tube is applied to all or part of the surface (00) except for both cross-sections of the finished VR tube Forming a chemical resin coating layer (01) penetrating 1 to 30 mm into the concrete surface, and a chemical resin lining layer (02) in which a nonwoven pad or a woven fabric of fiber or metal material is embedded thereon is formed to a thickness of 1 to 20 mm, By forming the donut-shaped cross-section lining dies 06 on both sides of the mold before molding the VR tube, the chemical resin lining layer 06 is formed to a thickness of 1 to 20 mm on both sides or the inner lining of the surface. In the same manner as the method, a nonwoven pad or a woven fabric made of a fiber or metal material is incorporated.

The lining application area can be applied to all the surfaces of the VR tube, but considering the economical efficiency, both the inner surface contacting with the waste water or the running water and on both end portions affecting the watertightness of the VR tube and a certain part of the outer surface inserted into the socket In the case of lining for the purpose of improving the structural strength of the VR tube, it is preferable to limit the inner lining to all the sides of the VR tube, and the lining of the inner side is also made of non-woven pads, fibers or metal materials. The chemical resin lining layer 02 into which the woven fabric of I was incorporated is formed into a multilayer.

The VR tube attached to the carrier, which is a habitat for the microbial treatment of the biologically purified wastewater, contacts the surface of the VR tube with a thermosetting chemical resin as shown in FIG. A chemical resin coating layer (01) penetrating 1 to 30 mm into the concrete surface is formed on all or part of the surface (00) except for both cross sections, and a chemical resin lining layer in which a nonwoven pad or a woven fabric of fiber or metal material is embedded thereon. (02) was formed to a thickness of 1 to 20 mm, and a chemical resin lining layer (06) was formed on both end surfaces by attaching and molding a donut-shaped cross-section lining die (06) to both end faces of the mold before molding the VR tube. Is formed to a thickness of 1 to 20mm, and the porous bio-ceramic lining layer (05) foamed to a thickness of 1 to 100mm thereon is formed as a carrier for incubation of microorganisms, and coated with a chemical resin thereon It is constructed by forming a high strength permeable lining layer (04) having an aggregate or perforated fibrous pad in a thickness of 3 to 30 mm.

At this time, the foamed porous ceramics lining layer is limited to all the inner surface of the lining application except for the socket molded part in contact with the waste water, and the high-intensity permeable lining layer incorporating the coarse aggregate coated with the chemical resin or the perforated fibrous pad It may not be formed when the amount of waste water contacting the VR tube is not high or the flow rate is low.The chemical resin lining treatment on both sides of the VR tube may be made of nonwoven pads or textile or metal fabrics treated in the same way as the inner chemical resin lining. It may be composed of the embedded chemical resin lining layer (02).

By realizing the prevention of decay of contact water, purified water, waste water treatment, etc.

First of all, the biggest disadvantage of the VR tube is to completely eliminate the risks of waterproofing and corrosion protection, which increases its lifespan, and prevents the outflow of wastewater, reducing the risk of groundwater and soil pollution, and greatly reducing the cost of maintaining facilities.

Secondly, it is possible to absolutely improve economic feasibility and shorten the construction period in preparation for all the construction costs for the same characteristics and functions.

Third, sewage pipes, water supply pipes and running water pipes themselves are highly biologically advanced treatments for safe clean water, anti-corruption, nitrogen and phosphorus without long-term maintenance, use and operation, which contributes to the improvement of water quality.
