The high-speed arch skeleton slope protection mold is processed according to the site pouring requirements for expressways and high-speed railways. How to ensure the good use of the formwork in the construction site, and can be used repeatedly without deformation, the quality of the formwork becomes the key. When using, the raw materials need to be poured into the mold, which needs to be reused for a long time. In order to increase the profit, the cost needs to be reduced. This can be achieved by reducing the frequency of replacement. Attention should be paid to the preservation, because the preservation environment directly affects the service life. First of all, before preservation, it should be noted that the protective layer should not be preserved when the protective layer is damaged, because the raw material of the high-speed arched skeleton slope protection mold is the steel plate used. When the steel plate contacts with the moist air, it is easy to rust, which will have a certain impact on the service life. Therefore, timely supplement should be made when the protective layer is damaged, so as to minimize the contact between the two, which can play a protective role to a great extent. During storage, attention should be paid not to put it in a humid environment. The environment should be kept dry, and the direct sunlight should be avoided. The direct sunlight will easily reduce the toughness of the steel plate, which will cause fracture during filling, which will damage the raw materials and cannot obtain the products. Because of the limited environment space, in order to make full use of the space, the high-speed arched skeleton slope protection mold needs to be stacked and saved, but the number of overlapping should not be too much, otherwise, the shape of the following high-speed arched skeleton slope protection mold will change, and it will be easy to leak slurry when using.
