Problems solved by technology

However, the traditional anti-corrosion and anti-seepage structure of the tunnel lining has single materials, simple layout, and poor anti-corrosion and anti-seepage performance. Although some have excellent anti-corrosion and anti-seepage performance, the construction steps are complicated and expensive. A new type of anti-corrosion and anti-seepage layer that can be used as a tunnel lining structure and its manufacturing method are of great significance

Embodiment 1

[0028] refer to figure 1 with figure 2 , in this embodiment, an anti-corrosion and anti-seepage layer is provided, and the anti-corrosion and anti-seepage layer is used as the inner lining structure of the circular tubular member 1 . The anti-corrosion and anti-seepage layer includes a bottom layer 2 attached to the component 1 and a surface layer 3 attached to the bottom layer 2 . Wherein, the bottom layer material forming the bottom layer 2 includes MMA waterproof material, that is, the bottom layer material may only be composed of MMA waterproof material, or may be mainly composed of MMA waterproof material. The surface layer material forming the surface layer 3 includes enamel, that is, the surface layer material can be composed only of enamel, or mainly composed of enamel.

[0029] Among them, the MMA waterproof material has good waterproof performance on the one hand, so that the anti-corrosion and anti-seepage layer can obtain good impermeability; on the other hand, ...

Embodiment 2

[0038] This embodiment provides a method for manufacturing the anti-corrosion and anti-seepage layer in Embodiment 1, which includes a surface treatment step, a bottom layer material coating step and a surface layer material coating step performed in sequence.

[0039] Firstly, the surface treatment step is carried out on the base surface 11 of the component 1 (the surface on which the anti-corrosion and anti-seepage layer needs to be attached), so that the roughness of the base surface 11 is within the range of CSP3-CSP5, so as to increase the bottom layer formed by subsequent coating The bonding force with the base surface 11 improves the firmness of the connection between the anti-corrosion and anti-seepage layer and the base surface 11.

[0040] Specifically, the surface treatment step includes the following sub-steps:

[0041] S1. Use mortar to repair the recesses on the base surface 11 (including but not limited to inner wall joints, holes, etc.), and the aggregate parti...

Abstract

The invention relates to an anti-corrosion and anti-seepage layer and a manufacturing method thereof. The anti-corrosion and anti-seepage layer includes a bottom layer for attachment to the component and a surface layer attached to the bottom layer. The bottom layer forming the bottom layer contains MMA waterproof material, and the surface layer material forming the surface layer contains enamel. The anti-corrosion and anti-seepage layer has good anti-corrosion and anti-seepage performance, simple manufacture, low cost and can be used as a tunnel lining structure. The above-mentioned manufacturing method comprises a base material coating step and a surface layer material coating step. In the base material coating step, the base material is coated on the base surface of the component that needs to form an anti-corrosion and anti-seepage layer, so as to form the base layer attached to the component; In the surface layer material coating step, the surface layer material is coated on the bottom layer to form a surface layer attached to the bottom layer. The method can produce an anti-corrosion and anti-seepage layer with good anti-corrosion and anti-seepage performance, simple manufacture and low cost, and can be used as a tunnel lining structure.

Description

technical field [0001] The invention relates to an anti-corrosion and anti-seepage layer and a manufacturing method thereof. Background technique [0002] With the continuous development of shield tunneling technology, its application in sewage pipelines is also increasing. In urban sewer facilities, ditches and pipes are almost all made of concrete. However, urban sewage often contains a large amount of salt solution, heavy metal solution, CH 4 , CO 2 and H 2 Chemical components such as S and small solid wastes will cause slow and continuous erosion of concrete and steel bars, which will affect the service life of the sewage tunnel; under the long-term groundwater and load, the tunnel will appear cracks or the gaps at the joints will become larger. Then there will be leakage and segment erosion, affecting the normal use of the tunnel and environmental safety. Therefore, it is of great significance to study how to prevent the tunnel from being corroded and leaked in the...
