Abstract
The utility model discloses a tunnel steel pipe piece composite bed anti -corrosion structure, the anticorrosion position of tunnel steel pipe piece includes the carbon steel board as the basic unit, still include as compound layer prevent the corrosion metals board, with preventing the corrosion metals board on the carbon steel board, prevent that the corrosion metals plate thickness accounts for 0.1%-20% of anticorrosion position gross thickness. The utility model discloses a tunnel steel pipe piece composite bed anti -corrosion structure has improved steel pipe piece corrosive protection performance, extension steel pipe piece service life. Both satisfy carbon steel plate structure intensity and rigidity requirement, satisfied the corrosion resistance requirement of preventing the corrosion metals board again. A large amount of uses of preventing corrosion metals can be practiced thrift to this kind of structure, and when guaranteeing technical requirement, reduce cost has very high economic value by a wide margin.
Description
Technical field
The utility model relates to the processing and manufacturing field of tunnel duct piece, especially a kind of tunnel steel tube sheet composite bed anti-corrosion structure.
Background technology
During subway shield tunnel construction, conventional steel sector-meeting is subject to the corrosion of underground and underground water, especially in coastal coastal area, underground and the corrosion of underground water to conventional steel section of jurisdiction even more serious.And existing conventional steel section of jurisdiction anticorrosive property is poor, rapid wear.
Therefore, adopt the mode that corrosion-resistant metal plate is combined with common carbon steel plate, solution underground and underground water are to the corrosion of conventional steel section of jurisdiction.
Utility model content
The utility model is solve the technical problem existed in prior art, and provides a kind of tunnel steel tube sheet composite bed anti-corrosion structure.
The technical scheme that the utility model is taked for the technical problem existed in solution prior art is:
A kind of tunnel steel tube sheet composite bed anti-corrosion structure, the anticorrosion position of tunnel steel tube sheet comprises the carbon steel sheet as basic unit, also comprise the corrosion-resistant metal plate as cladding, with corrosion-resistant metal plate in described carbon steel sheet, described corrosion-resistant metal plate thickness accounts for 0.1% ~ 20% of anticorrosion position gross thickness.
The extrados of the ring flat-plate of described tunnel steel tube sheet and top, two sides are all with corrosion-resistant metal plate.
The end face of the end plate of described tunnel steel tube sheet and top, two sides are all with corrosion-resistant metal plate.
The anticorrosion position of described tunnel steel tube sheet adopts anticorrosion steel or corrosion-resistant metal plate to make cladding by heat pressing process.
The advantage that the utility model has and good effect are:
Tunnel steel tube sheet composite bed anti-corrosion structure of the present utility model, improves steel pipe sheet anti-corrosion capability, extends steel pipe sheet service life.Both meet carbon steel sheet structural strength and stiffness requirement, meet again the corrosion resistance requirement of corrosion-resistant metal plate.This kind of structure can save the use of a large amount of corrosion-resistant metal, while guarantee technical requirements, significantly reduces costs, has very high economic worth.

Detailed description of the invention
Referring to drawings and Examples, the utility model is described in detail.
As Figure 1-4, tunnel steel tube sheet composite bed anti-corrosion structure of the present utility model, the anticorrosion position 1 of tunnel steel tube sheet comprises the carbon steel sheet 2 as basic unit, also comprise the corrosion-resistant metal plate 3 as cladding, with corrosion-resistant metal plate 3 in described carbon steel sheet 2, described corrosion-resistant metal plate 3 thickness accounts for 0.1% ~ 20% of anticorrosion position 1 gross thickness.
The extrados of the ring flat-plate of described tunnel steel tube sheet and top, two sides are all with corrosion-resistant metal plate 3.
The end face of the end plate of described tunnel steel tube sheet and top, two sides are all with corrosion-resistant metal plate 3.
The anticorrosion position of described tunnel steel tube sheet adopts anticorrosion steel or corrosion-resistant metal plate to make cladding by heat pressing process.
Tunnel steel tube sheet composite bed anti-corrosion structure of the present utility model, improves steel pipe sheet anti-corrosion capability, extends steel pipe sheet service life.Both meet carbon steel sheet structural strength and stiffness requirement, meet again the corrosion resistance requirement of corrosion-resistant metal plate.Usually only account for 0.1% ~ 20% of the anticorrosion position of tunnel steel tube sheet due to corrosion-resistant metal plate, this kind of structure can save the use of a large amount of corrosion-resistant metal, while guarantee technical requirements, significantly reduces costs, has very high economic worth.
Tunnel steel tube sheet of the present utility model is adding man-hour, adopts and mends method technique or welding method technique by replacing a damaged part, in order to reach the Korrosionsmediums such as opposing acid, alkali to the harm of steel pipe sheet.
