{dede:global.cfg_gsname/} | Updated: 2020-06-30 09:06:07
To introduce the causes of the damage of the trench cover plate, so that we can better use prevention.
1. Economic selection of trench cover and comprehensive technical and economic analysis. As a new building material, steel plate is widely used in metallurgy, mining, petroleum, electric power, industry and some civil fields. This so-called new material has a history of more than ten years abroad, but it has been widely used in China for nearly ten years. But it is like aluminum alloy doors and windows, compared with traditional materials, people used to call it new materials.

2. Due to the chemical corrosion and electrochemical corrosion, corrosion and electrochemical corrosion lead to the weakening of the cross-section of the trench cover plate. Surface treatment is recommended. In addition, it also includes the design of trench cover plate, production process of trench cover plate, installation failure of galvanized steel plate, illegal use and operation, etc.
3. Due to the change of load and long-term use, the bearing capacity of the trench cover plate will change, and the deformation and deformation will occur. When the concave groove cover plate becomes weak, the components will be twisted, and the connection cracks, cracks and deformation are all caused by temperature difference.
4. When the trench cover is used for a long time, it will be damaged. In order to make the trench cover plate meet the requirements as much as possible, the maintenance of the trench cover plate should be carried out at ordinary times. The maintenance of outdoor trench cover plate is generally called protection, anti-corrosion, fire protection, etc. the service life of antirust paint is limited, and the galvanizing effect will be better, especially when the steel parts are closed and cannot be maintained.
