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 anti-seepage layer and a manufacturing method thereof. The anti-corrosion anti-seepage layer comprises a bottom layer used for being attached to a member anda face layer used for being attached to the bottom layer, a bottom layer material for forming the bottom layer comprises an MMA waterproof material, and a face layer material for forming the face layer comprises porcelain glaze. The anti-corrosion anti-seepage layer is high in corrosion resistance and seepage resistance, easy to manufacture and low in cost and can be used as a tunnel lining structure. The manufacturing method comprises the steps of coating the bottom layer material, wherein the bottom layer material coats a base face of the anti-corrosion anti-seepage layer to be formed of the member to form the bottom layer attached to the member; coating the face layer material, wherein the face layer material costs the bottom layer to form the face layer attached to the bottom layer. By means of the method, the anti-corrosion anti-seepage layer which is high in corrosion resistance and seepage resistance, easy to manufacture and low in cost and can be used as the tunnel lining structure can be manufactured.

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...
