Before the start of the project, the professional and technical personnel shall make technical disclosure to the project construction personnel, clarify the quality requirements and quality standards of each process, and the preventive measures for possible quality accidents; All participants in the construction of the project should understand the connection form of each diaphragm unit node, and must undergo professional operation training and professional safety education before entering the construction site.

Before going to work every day, group disclosure should be carried out to achieve a clear division of labor, and the position should be clear before the membrane installation should check all the connection points related to the membrane surface for splashes, burrs and other phenomena, and should ensure that there are no sharp spikes; Before the membrane is installed, cover the peripheral components that may damage the membrane with a cotton cloth; After the diaphragm is opened, it is necessary to check whether the hole position is correct, whether there are scars on the membrane surface and the surrounding bolts of the contaminated screw are fixed, and they should be inspected one by one to ensure that the bolts are not missing and there is no leakage.

When installing the splint, it must be ensured that the edge of the membrane edge rope is exposed on the outside of the upper splint, and if the edge of the membrane rope enters the middle of the two splints, it must be treated in time before tensioning and reported a treatment order.

The membrane installation platform, climbing scaffolding and safety protective railings erected at the construction site should ensure that the safety > is firm and there is no hidden danger of accidents; On-site safety facilities must be erected by full-time personnel, and no other personnel shall dismantle or loosen them at will, and safety facilities should be inspected and repaired before construction every day.

The protection of the membrane surface should be carried out throughout the entire process from transportation, lifting, unfolding and installation.

When lifting the diaphragm, safety must be ensured, : pay attention to listen to the weather forecast, the wind force is greater than 4 can not be operated, the diaphragm lifting has a special person to command, to prevent the membrane surface from being torn due to uneven force; Arrange the lifting time of each membrane unit, according to the weather forecast, to deploy a membrane unit, and temporarily pull the perimeter of the membrane on the same day to ensure the safety of the membrane overnight.

When installing the diaphragm, the installation tool shall not be thrown at will to prevent damage to the membrane surface; When the installer walks on the membrane surface, it is strictly forbidden to wear leather shoes, and must wear soft-soled work shoes to ensure that the sole is free of pollutants; When working at height, it is strictly forbidden to throw objects downward, and use tools to apply ropes and harnesses or tool bags to prevent loss.

Tighten the membrane boundary bolts, and it is strictly forbidden to use a live wrench; Small tools must be placed in a tool bag, all loose parts must be collected in a container and not more than a flat mouth, scattering is strictly prohibited, and it is not allowed to hold objects up and down with both hands and use defective tools; High-altitude operators should meet the physical requirements of ultra-high-altitude construction, and construction after drinking is strictly prohibited; For the installed diaphragm, before tensioning, it should be checked regularly to prevent the bolt from loosening due to wind vibration until the project is completed.
