Abstract
The utility model discloses a tunnel cement pipe piece combined material anti -corrosion structure, including concrete layer, still include the preserving timber bed of material, the anti -corrosion material layer is equipped with to last the scribbling of concrete layer, preserving timber thickness of bed accounts for 0.01%-20% of cement pipe piece gross thickness. The utility model discloses a tunnel cement pipe piece combined material anti -corrosion structure has improved cement pipe piece corrosive protection performance, extension cement pipe piece service life. Both satisfy concrete layer structural strength and rigidity requirement, satisfied the corrosion resistance requirement of epoxies, resin class or liquid coating class anti -corrosion material again to still add the additives such as glass silk, glass fibre, iron wire, steel wire or mineral powder that have multiplicable intensity. The use of a large amount of epoxiess, resin class or liquid coating class anti -corrosion material 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 concrete pipe sheet composite material anti-corrosion structure.
Background technology
During subway shield tunnel construction, traditional concrete pipe can be subject to the corrosion of underground and underground water, especially in coastal coastal area, underground and the corrosion of underground water to traditional concrete pipe even more serious.And existing traditional concrete pipe anticorrosive property is poor, rapid wear.
Therefore, adopt the mode that anticorrosive is combined with concrete pipe sheet, solution underground and underground water are to the corrosion of traditional concrete pipe.
Utility model content
The utility model is solve the technical problem existed in prior art, and provides a kind of tunnel concrete pipe sheet composite material 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 concrete pipe sheet composite material anti-corrosion structure, comprise layer of concrete, also comprise the preserving timber bed of material, described layer of concrete is coated with the preserving timber bed of material, described anti-corrosion material layer thickness accounts for 0.01% ~ 20% of concrete pipe sheet gross thickness.
End face and the top, two sides of described tunnel concrete pipe sheet are all coated with the preserving timber bed of material.
The described preserving timber bed of material is made up of epoxies, resinae or liquid coating class material, is also added with glass fiber, glass fiber, iron wire, steel wire or mineral powder in the preserving timber bed of material.
Described tunnel concrete pipe sheet adopts the anti-corrosion material of epoxies, resinae or liquid coating class to make cladding by coating process.
The advantage that the utility model has and good effect are:
Tunnel concrete pipe sheet composite material anti-corrosion structure of the present utility model, improves concrete pipe sheet anti-corrosion capability, extends concrete pipe sheet service life.Both layer of concrete structural strength and stiffness requirement had been met, meet again epoxies, resinae or liquid coating class anti-corrosion material corrosion resistance requirement, and be added with the additives such as glass fiber, glass fiber, iron wire, steel wire or the mineral powder that can gain in strength.This kind of structure can save the use of a large amount of epoxies, resinae or liquid coating class anti-corrosion material, while guarantee technical requirements, significantly reduces costs, has very high economic worth.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is lateral view of the present utility model;
Fig. 3 is the schematic enlarged-scale view in A portion in Fig. 2.
Wherein: 1: layer of concrete 2: the preserving timber bed of material.
Detailed description of the invention
Referring to drawings and Examples, the utility model is described in detail.
As Figure 1-3, tunnel concrete pipe sheet composite material anti-corrosion structure of the present utility model, comprises layer of concrete, also comprises the preserving timber bed of material, described layer of concrete is coated with the preserving timber bed of material, described anti-corrosion material layer thickness accounts for 0.01% ~ 20% of concrete pipe sheet gross thickness.
End face and the top, two sides of described tunnel concrete pipe sheet are all coated with the preserving timber bed of material.
The described preserving timber bed of material is made up of epoxies, resinae or liquid coating class material, is also added with glass fiber, glass fiber, iron wire, steel wire or mineral powder in the preserving timber bed of material.
Described tunnel concrete pipe sheet adopts the anti-corrosion material of epoxies, resinae or liquid coating class to make cladding by coating process.
Tunnel concrete pipe sheet composite material anti-corrosion structure of the present utility model, improves concrete pipe sheet anti-corrosion capability, extends concrete pipe sheet service life.Both meet layer of concrete structural strength and stiffness requirement, met again the corrosion resistance requirement of epoxies, resinae or liquid coating class anti-corrosion material, and be added with the additives such as glass fiber, glass fiber, iron wire, steel wire or the mineral powder that can gain in strength.Because epoxies, resinae or the liquid coating class preserving timber bed of material only account for 0.01% ~ 20% of tunnel concrete pipe sheet thickness usually, this kind of structure can save the use of a large amount of epoxies, resinae or liquid coating class anti-corrosion material, while guarantee technical requirements, significantly reduce costs, there is very high economic worth.
Tunnel concrete pipe sheet of the present utility model is adding man-hour, adopts the technique of application epoxies, resinae or liquid coating class anti-corrosion material, in order to reach the Korrosionsmediums such as opposing acid, alkali to the harm of concrete pipe sheet.
