We all know that membrane construction works under normal conditions, are in the sunny days. But because now many construction engineering team to catch the rainy day will choose to continue construction, but in the rainy day construction is also dangerous, that membrane structure works in rainy days when the construction should pay attention to what?

Membrane structure works in rainy days before the work preparation, the choice of rainy days to carry out a detailed site investigation, according to the fact that the construction of the rainy Day construction organization plan, this is the most important thing.

Before the construction of the membrane structure is the most important thing is to build the tunnel and keep clear rain smooth, to build temporary drainage facilities, to ensure that rainy days when the site is not flooded and can timely eliminate the ground water.

First of all, in rainy days when construction, the temporary shelter should be constructed, rain should not fall on the hot weld. If the welding site is relatively humid, must be wiped with a dry cloth and before welding with oxygen acetylene flame dry, keep the seam dry, no residual moisture.

Hoisting: If there is water on the component, should be cleaned before installation, but must not damage the coating, high-strength bolt joint installation, the component friction surface should be clean, can not have water droplets, more can not rain and contact with dirt and oil and other dirty things.

In rainy days, the components can not be brushing work, if the situation of heavy rain to stop the construction immediately, to ensure the quality of membrane structure and personnel safety.
