Description

Medium and large diameter cross section reinforcement method

The present invention relates to the cross-sectional reinforcement method of the medium- and large-diameter pipeline, and more particularly, to a part or the entire cross section of the transverse direction and to the longitudinal reinforcement in the longitudinal direction as a partial or total reinforcement in the longitudinal direction After installing one of the directional extension reinforcing bar, and then install the reinforcing reinforcement on one of the transverse reinforcement or the transverse reinforcing bar, and then cross-section of medium and large diameter pipes to be reinforced by the filling material to be embedded It is about reinforcement method.

In general, the purpose of the pipe is the rainwater pipe and sewage pipe used for sewerage, the water supply pipe, the waterway pipe, and is made of steel, concrete, and resin, which is long in the longitudinal direction in the cross-sectional shape of round, square, and polished shapes. In the pipeline, the soil or gravel rapidly rolls down or impacts with the running water, and it starts to break from the bottom or joint of the pipeline, causing corrosion of the rebar or steel pipe. In addition, the inner surface of the pipeline may be damaged, and in addition, the outer surface of the pipeline may be damaged or corroded due to the influence of groundwater or waste water. Due to the effects of vibration or earthquake caused by passing the vehicle, This factor is the situation that exists in various direct and indirect.

When reinforcing the pipeline due to the above factors of damage to the pipeline, the entire cross section of the transverse direction, such as round, square or horseshoe type, is targeted, and in the longitudinal direction, it is divided into partial repair and full repair. The repair or reinforcement method, which is composed of mortar, rubber and stainless steel plate with reinforcement material, is applied.

For example, in order to increase the strength reinforcement effect while minimizing the reduction of the cross section of the inner surface of the pipeline, the entire cross section of the pipeline is applied, and in the longitudinal direction, the adhesive is applied to the inner surface of the pipeline for partial or total repair or reinforcement. In the case of the method configured to fix by using reinforcement wrapped around the spacer and reinforcing bar on the outer surface of the wire mesh, and then plastering on the reinforcing material, the cross section of the transverse direction such as circular, square, or horseshoe type is covered. Even if the adhesive strength of the adhesive material is relatively small or reduced in the form of reinforcement, the impact of the reinforced part is deviated from the inner surface of the pipeline or the strength reinforcing effect may be reduced. Only some cross-sections such as the lower part or specific part of the pipeline When reinforcing the entire section including the remaining sections except for the partial section by connecting to the partial section secondly with a predetermined time difference after the reinforcement, the partially reinforced section may be reinforced even by using an adhesive material. There is a problem in that the cross section is damaged or impacted and separated from the inner surface of the pipeline to cause defects or reconstruction.

In relation to the above, in the case of concrete pipelines, damage or deterioration causes the rebar to be rusted to repair or reinforce the existing pipelines for repair or reinforcement, and then use anchoring anchors to damage the structure. There is a problem in that the effect is reduced, and in the case of steel pipes, corrosion is repaired to remove the rust from the corrosion-prone areas and apply the anticorrosive material without applying the fixing method. Abrasion had a weak problem.

In addition, when the pipeline is integrally constructed without joints, a method of reinforcing the exterior of the pipeline by grouting has not been developed. The grout material is mainly injected for the purpose of indexing through only the joint of the pipeline. In the case of the construction method, a partial grout is performed only on the periphery of the joint, and the entire grout is performed on the outer surface of the pipeline, so that the strength of the pipeline cannot be reinforced.
