middle and large-diameter pipeline section reinforcement

摘要

The present invention relates to a reinforcement of the cross section, large diameter pipelines, for some species cross-section in the pipeline for this purpose and securing the support near the process direction, after the process step of the installation for one thing from the reinforcement transverse bars or transverse cross-section extending for part, after the process is to one phase from the reinforcement bars for laterally or transversely extending Some steps of installing a secondary reinforcement mesh section for the process after the process of applying the adhesive and is president and anti-corrosive material for some section in the pipeline, the process after plastering a filler for some cut-out on the president and anti-corrosive adhesive material for some section a step of, after the process is characterized in comprising a step of coating the surface finishing material for the scene for non-cross-sectional portion on the filler section. ; In addition, the cross-section of a part of a reinforcement pipe target excluded process and the process after the rest of the cross-section of this part, except for the section on the end portion of the transverse reinforcement section extends for some part of the section is configured to skip the installation of longitudinal muscle support for the rest of the section, except for the reinforcement of the rest of the section process and be substituted for installation by connecting the lateral reinforcement for the process to be replaced after the process and to install secondary reinforcement mesh partial cross section was excluded on the transverse bars for the rest of the section excluded some sections, after the process process and the process for the rest of the section after the network has been excluded cross-sectional president and the Audience Award adhesive material for the rest of the section is substituted for section excluded that some anti-corrosive coating the adhesive material for the rest of the section president and excluded some section within the pipeline Secondary reinforcement process and to be substituted for plastering the filler for the rest of the section to be excluded that some section purchases, the process for the rest of the surface finish after a cross-section of this part, except the US scene for the rest of the section on the filler section exclude some section is characterized in consisting of a coating step is substituted for. ; On the other hand, the steps of installing a maintenance target hypothesis inlet channel to reinforce the cross-section from the outside of the pipe, after the process is over the hypothesis inlet a step of, after the step of injecting grout material is a step of removing the hypothesis inlet, after the process is characterized in comprising a step for filling fill material into the injection port of the hypothesis space inlet.
