Analyze the plugging plan of the screw hole through the wall

1. Production and construction methods:

Before the exterior wall plastering construction, use the waterproof mortar mixed with 10% expansive cement to tamping, and then use 1:2 cement mortar twice to paint and smooth. Use cement mortar to ram the screw hole on the inner wall and smooth the two ends.

2. Construction quality measures

Set up a dedicated person responsibility system, and the construction staff will make technical clarifications to the team on the repair of the screw hole, and then check and evaluate the repair of the wall screw hole to ensure the correctness of the construction.

Three, safety assurance measures

1. The construction site should strictly implement safety production regulations and all relevant safety production documents, improve and implement the engineering safety production responsibility system, and earnestly implement the policy of safety first and prevention first, and achieve safe production and civilized construction . (Guide: Standard content in several aspects of fastener products)

2. All operators participating in the construction must be trained in safe technical operation before entering the site for construction. Entering the construction site must consciously abide by the six disciplines of on-site safety production. All types of work and procedures should be provided by the constructor in writing before construction can be carried out.

3. It is necessary to make a safety report to the operator before construction and make a good record.

4. Do not blindly deal with unidentified underground situations during construction. When there is a conflict between the construction schedule and safety, safety should be the first priority, and employees should raise their safety awareness.

5. In the event of accidents and accidental seedlings, it is necessary to do three things that are not let go, that is, the cause of the accident (seedlings) is not clear, and the persons responsible for the accident (seedlings) and the masses have not received education and training. Don't let it go, put an end to hidden dangers of accidents.

6. According to the construction characteristics of this project, combined with the safety production system and relevant regulations, the full-time safety officer shall conduct frequent on-site inspections. If serious unsafe conditions are found, they have the right to order to stop the construction and report to the project manager immediately. Construction can continue only afterwards.

7. Construction is strictly forbidden in weather with winds of category 6 or above, thunder and lightning, and rainstorms. During the typhoon season, staff on duty at night shall be allocated to ensure the safety of the project.

8. The performance of the tools used in construction should be checked regularly, especially the force-bearing tools should be complete, to prevent accidents such as slippage, slippage, etc. from injuring people and self.
