Manufacturing method of immersed tube tunnel steel shell tube section and immersed tube tunnel steel shell tube section

Abstract

The invention discloses a manufacturing method of an immersed tube tunnel steel shell tube section and the immersed tube tunnel steel shell tube section, and relates to the technical field of large steel structure manufacturing engineering. The manufacturing method comprises the following steps that S1, first datum line design is conducted on T-shaped profiles, profile steel, transverse partitionplates and longitudinal partition plates, and first datum line design and second datum line design are conducted on inner shell plates and outer shell plates; S2, a plurality of T-shaped profiles, a plurality of pieces of profile steel, a plurality of transverse partition plates, a plurality of longitudinal partition plates, an inner shell plate and an outer shell plate are spliced into a block body according to the first datum line; S3, four blocks are pre-assembled into a small section according to the second datum line; and S4, multiple small sections are folded into a tube section according to the second datum line. Splicing is carried out according to the first datum line, so that parts do not need to be measured, operation is simplified, accurate positioning of all the parts is guaranteed, and precision control over block splicing is achieved.

Description

Technical field [0001] The present invention relates to the field of engineering large-scale steel production technology, in particular, the production method of tunnel steel pipe section relates to an immersed tube and steel tube immersed tunnel section. Background technique [0002] Currently, immersed tunnel pipe sections due to the large steel structure, are integrally molded by splicing a plurality of members, during splicing part to part, the relative position between the member and the member basically depends on the observation position measuring instrument, after the observation result is fed back to the operator, and then bias adjustment. Since the combining process parts and components, parts and components, and the component parts, there is no intuitive relationship between the reference position, the assembly process is difficult to achieve accurate positioning between each other; and because there is no step between the visual association point product easily lead t...

Problems solved by technology

Since there is no intuitive positional relationship reference in the assembly process of parts and parts, parts and parts, and parts and parts, it is difficult to accurately locate each other during the assembly process; at the same time, because there is no intuitive connection point between process products , it is easy to cause inconsistencies in the measurement benchmarks, resulting in structural docking deviations, which will eventually affect the splicing of the steel shell tube joints of the entire immersed tunnel
