The grid company needs to pay attention to the grid construction in bad weather: when the grid company is carrying out the grid construction and installation, it often encounters a lot of bad weather. In this environment, we cannot stop the construction of the grid because of the unsatisfactory environment. Therefore, we should pay attention to some problems during construction in a lot of rainy weather.

The grid company needs to pay attention to the grid construction in bad weather. How does the grid company carry out the grid construction in bad weather?

1. Grid construction In rainy weather, the grid components cannot be painted.

2. When the grid project is constructed in rainy weather, it is advisable to set up a temporary protective shed, and rainwater shall not fall on the hot weld. If the welding part is wet, it must be wiped with a dry cloth and dried with an oxyacetylene flame before welding to maintain the connection. The seams are dry and there is no residual moisture.

3. Because the air is relatively humid in rainy days, the welding rod should be stored in moisture-proof and baked. The repeated baking of the same welding rod should not exceed two times, and the management personnel should make a baking record in time.

4. In case of windy weather during grid construction, large components such as columns, main beams, supports, etc. should be corrected immediately. After the correct position is corrected, they should be permanently fixed to prevent unilateral instability. The components installed on the same day should be corrected. Form a spatially stable system.

5. Roof insulation construction cannot be carried out on rainy days and strong winds above level 5.

6. When hoisting the grid project in rainy weather, if there is water on the components, they should be cleaned up before installation, but the coating should not be damaged. When the high-strength bolt joints are installed, the friction surface of the components should be clean without water drops, let alone rain. And contact with dirt, oil and other dirt.

The above are the items that the grid company needs to pay attention to when the grid construction is carried out in inclement weather.
