Research and development of finished rubber-lined pipeline reserved hole construction process

Abstract

The invention discloses research and development of a finished rubber-lined pipeline reserved hole construction process, and relates to the technical field of rubber-lined pipeline reserved hole construction. The research and development includes the steps of early-stage technology preparing which includes drawings familiarizing, data collecting, drawing review and inter-professional drawing review, and the mastering of requirements and construction details of drawings; construction preparation which includes data collection, scheme research, reserved hole construction method determination, material preparation, and complete mold manufacturing; drawing reviewing; construction characteristics analyzing; material inspecting; construction control; surveying and setting out; concrete pouring protection; rubber-lined pipeline welding; mold removal; and checking and accepting. The drawing review means comparing and checking civil engineering structure design drawings and the drawings such asequipment installation related to the next procedure by a project technical manager before starting the construction. According to the research and development of the finished rubber-lined pipeline reserved hole construction process, the service life of a pipeline is greatly prolonged, the cost of a user is reduced, the construction time is shortened, and manpower, material resources and financial resources for the construction are saved.

Description

technical field [0001] The invention relates to the technical field of construction of reserved holes for rubber-lined pipelines, in particular to the research and development of a construction process for reserved holes for finished rubber-lined pipelines. Background technique [0002] The rubber-lined pipe is a pipe with a steel or hard structure as the pipe skeleton, and wear-resistant, anti-corrosion, and high-temperature-resistant rubber as the lining layer. Through the physical and chemical properties of the rubber itself, the impact of the pipeline conveying medium on the external structure is reduced. Due to the buffering effect of rubber, it greatly prolongs the service life of the pipeline and reduces the user's cost. Therefore, this technological innovation has a great impact on reforming technology, saving costs and speeding up progress. In recent years, due to the expansion and development of the construction market, many enterprises have unfair and vicious comp...

[0002] The rubber-lined pipe is a pipe with a steel or hard structure as the pipe skeleton, and wear-resistant, anti-corrosion, and high-temperature-resistant rubber as the lining layer. Through the physical and chemical properties of the rubber itself, the impact of the pipeline conveying medium on the external structure is reduced. Due to the buffering effect of rubber, it greatly prolongs the service life of the pipeline and reduces the user's cost. Therefore, this technological innovation has a great impact on reforming technology, saving costs and speeding up progress. In recent years, due to the expansion and development of the construction market, many enterprises have unfair and vicious competition, which generally reduces the unit price of construction, so it is difficult to guarantee the construction quality. Only by adopting new technology and new technology in the construction process can we not only ensure the construction quality but also save costs and create greater profits for the company

[0003] In recent years, the country has paid more and more attention to environmental protection, desulfurization device has become a necessary process, and the finished carbon steel rubber-lined pipeline is used more and more frequently. Due to its unique particularity, the construction requirements for reserved holes are higher. Not much research energy has been invested in the construction technology of the reserved opening, because it is relatively small, but there is no good construction technology. In foreign countries, rubber-lined pipelines are widely used, but most industrial plants in foreign countries are steel structures. Holes can be opened according to the site, and domestic reference can also be made. According to the development trend of the construction industry in modern society, whether in industrial buildings or civil buildings, innovative construction techniques and updated construction technologies can meet the development needs of the construction industry. In order to keep up with the pace of the times, most of the construction industry is still at the original construction level. There is not much technological innovation and more advanced construction techniques. Reserving holes has always been a common quality problem in civil engineering site construction. , large amount of engineering, high technical requirements, short construction time, high position accuracy, and high verticality requirements for the upper and lower floors. The finished carbon steel rubber-lined pipelines are not allowed to be cut and welded on site. All are supplied by the manufacturer to length and bolted on site. It is required to reserve holes for more accurate positions during construction, otherwise the floor will have to be re-opened, which will not only affect the structure but also consume manpower, material and financial resources, and affect the progress of the project. For this reason, we propose a construction process for reserved holes for finished rubber-lined pipes research and development
