Example Embodiment

[0030] Example 1

[0031] The method for comprehensively plugging and repairing elevator shaft leakage is characterized by including the following steps:

[0032] (1) Finding water seepage points: In order to find water seepage points easily, remove the cement mortar paint layer and waterproof material layer in the elevator shaft before the leak stoppage construction;

[0033] (2) Perform plugging construction treatment according to the characteristics of the seepage point. If the characteristics of the seepage point are point leakage, the direct plugging method is used to stop the leakage. The material used in the direct plugging method is watertight; if the characteristics of the seepage point are For line leakage or surface leakage, the pressure grouting method is used to plug the leakage, and the materials used for the pressure grouting method are water-soluble polyurethane and acrylate;

[0034] (3) Make a waterproof layer on the back water surface with the polymer beneficial cem...

Abstract

The invention provides a comprehensive plugging and repairing method for elevator shaft leakage. The comprehensive plugging and repairing method comprises the following steps that (1) a water seepagepoint is searched, specifically, in order to facilitate search of the water seepage point, a cement mortar paint layer and a waterproof material layer in an elevator shaft are removed before pluggingconstruction; (2) according to the characteristics of the water seepage point, plugging construction treatment is carried out, if the characteristic of the water seepage point is point leakage, a direct plugging method is used plugging, and a material used in the direct plugging method is Shuibulou; if the characteristic of the water seepage point is line leakage or surface leakage, a pressure grouting method is used for plugging, and materials used in the pressure grouting method are water-soluble polyurethane and acrylate; and (3) after plugging construction treatment, a waterproof layer made of a polymer waterproof and cracking resistant mortar material is arranged on the back surface.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a method for comprehensive plugging and repairing of elevator shaft leakage. Background technique [0002] Water seepage in elevator shafts can affect normal travel at least, and cause electric shocks at worst, endangering personal safety! Therefore, the leakage control and repair work of elevator shafts is very important. It is best to have a leakage repair method that can treat both symptoms and root causes, and achieve long-term effective governance effects. [0003] At present, many elevator shaft plugging methods on the market are palliative, not the root cause. Where there is a leak, plug it up. After structural settlement cracks or temperature cracks appear in daily use, the leakage reappears, and the leak needs to be plugged again. The leakage control of the elevator shaft is not thorough, which seriously affects the operation safety of the elevator and ...
