Analysis of plugging seepage and plugging technology
1. Leakage.
In construction, we often encounter various leakage problems, such as roof leakage, exterior wall water seepage, ground water leakage, etc. These problems not only affect the aesthetics of the building, but also may affect the functional function and longevity of the building.
Second, the cause of leakage.
There are many reasons for leakage, the main ones are the following:
1.Construction quality problems: the waterproof treatment in the construction process is not in place, such as uneven waterproof coating, unreal membrane pasting, etc.
2.Structural deformation: The structure of the building is deformed or settled, resulting in the destruction of the waterproof layer.
3.Material problems: the quality of the waterproof material is unqualified, or it is invalid for too long a time.
4.Improper maintenance: daily maintenance work is not in place, such as failing to clean up stagnant water in time, failing to repair damaged parts in time, etc.
3. Plugging seepage and leakage technology.
Plugging and leakage plugging technology is a solution specifically for the problem of building leakage, mainly including waterproof coating, waterproof membrane, grouting and other technical means.
1.Water-repellent coating.
Waterproofing coating is a commonly used waterproofing measure that achieves a waterproof effect by applying waterproof coating to the surface to form a dense waterproof layer. Commonly used waterproof coatings are polyurethane, polymer cement, etc. When choosing a waterproof coating, you should consider the use environment and use of the building, and choose a suitable waterproof coating. At the same time, it is necessary to ensure that the painting is uniform and there are no omissions.
2.Waterproofing membrane.
Waterproofing membrane is a commonly used waterproofing material, usually used on roofs, exterior walls and other parts. Commonly used waterproofing membranes include asphalt membranes, synthetic polymer membranes, etc. Before construction, the quality and specifications of the coil should be checked to ensure that the requirements are met. During the construction process, it should be ensured that the coil is firmly pasted and there are no bubbles, wrinkles and other problems.
3.Grouting technology.
Grouting is a method of filling cracks and blocking leaky channels by injecting a viscous slurry. According to the different leakage parts, different grouting materials can be selected, such as cement slurry, sodium silicate slurry, etc. Before grouting, the leakage site should be surveyed to determine the location and number of grouting holes. The amount and pressure of the slurry should be controlled during grouting to ensure that the slurry can fully fill the leakage channel.
In addition to the above technologies, there are other plugging and leakage plugging technologies, such as mechanical plugging, elastic seal plugging, etc. Each of these techniques has its own characteristics, and the appropriate method can be selected according to the specific situation.
Fourth, maintenance.
For buildings that have leakage problems, in addition to repairing them with plugging and plugging technology, daily maintenance work should also be strengthened. The main points include the following:
1.Regular inspection: Regularly check the waterproofing of all parts of the building, and deal with leakage problems in a timely manner.
2.Clean up stagnant water: Clean up stagnant water daily to avoid damage to the waterproof layer.
3.Repair the damaged parts: For the parts that have been damaged, they should be repaired in time to restore the waterproof performance.
4.Choose the right maintenance personnel: For large-scale repair projects, you should choose experienced and professional maintenance personnel to ensure the quality of maintenance work.
In short, plugging and plugging technology is an important means to solve the problem of building leakage. In the construction process, the construction quality should be strictly controlled, and appropriate materials and processes should be selected. In daily use, maintenance work should be strengthened to ensure that the waterproof performance of the building is always in good condition. Only in this way can we effectively avoid all kinds of losses and impacts caused by leakage problems.
