1. Overview.
Elevator shaft plugging refers to the construction process of repairing water leakage and rain leakage in the elevator shaft. Before carrying out leak plugging construction, it is necessary to understand the structure of the elevator shaft, the causes of water leakage and the construction difficulties, and formulate the corresponding construction plan. This guide will introduce the preparation, construction process and precautions for the construction of elevator shaft plugging, and provide reference for related construction.

2. Preparation for construction.
1.Understand the structure of the elevator shaft: Before construction, it is necessary to understand the structure of the elevator shaft, including the hoistway, machine room, pit and other parts, so as to take corresponding plugging measures for different parts.
2.Determine the cause of water leakage: investigate and analyze the cause of water leakage in the elevator shaft, such as waterproof layer damage, pipeline leakage, etc., so as to take corresponding treatment methods.
3.Prepare materials and tools: According to the construction needs, prepare corresponding waterproof materials, plugging materials, tools, etc.
4.Formulate the construction plan: according to the structure of the elevator shaft and the cause of water leakage, formulate a detailed leakage plugging construction plan, including the construction process, operation steps and safety precautions.
Third, the construction process.
1.Clean the base layer: clean the base layer in the elevator shaft, including dust, dirt, etc., to ensure that the surface of the base layer is clean and flat.
2.Coating base treatment agent: Brush the base treatment agent on the surface of the base layer to improve the adhesion between the waterproof material and the base layer.
3.Additional layer treatment: In key parts such as elevator shafts and machine rooms, waterproof materials are used to do additional layer treatment to enhance the waterproof effect.
4.Plugging treatment: For the leakage part, the corresponding plugging material is used for plugging treatment. For pipe leaks, the pipes need to be replaced or treated with special plugging materials.
5.Waterproof layer construction: apply waterproof paint on the bottom and surrounding surfaces of the elevator shaft to ensure that the painting is uniform and no omissions.
6.Acceptance: After the construction is completed, the elevator shaft is filled with water or water test to ensure that the plugging effect is good and there is no leakage.
4. Precautions.
1.During the construction process, attention should be paid to safety to avoid accidents. In particular, when working at height, corresponding safety measures should be taken.
2.When applying waterproof coatings, attention should be paid to the thickness and uniformity of the brushing to avoid missing or uneven coating.
3.When plugging the leakage, the corresponding treatment methods should be taken according to the different causes of water leakage. For pipeline leakage, attention should be paid to replacing the pipeline or using special plugging materials for treatment.
4.During the construction process, attention should be paid to protecting the elevator equipment to avoid damage or contamination to the equipment.
5.When carrying out acceptance, it should be ensured that the results of the irrigation test or the drenching test meet the requirements and that there is no leakage. If there are unqualified parts, they should be repaired and treated in time.
5. Summary. Elevator shaft plugging construction is an important project, which is of great significance for ensuring the safe operation and prolonging the service life of the elevator. Before the leakage plugging construction, it is necessary to fully understand the structure of the elevator shaft and the cause of water leakage, and formulate a detailed construction plan. During the construction process, attention should be paid to safety, quality and management to ensure the smooth progress of construction. At the same time, attention should be paid to checking and testing the plugging effect during acceptance to ensure that there is no leakage.
