The cable corridor is an important part of the power system, and its sealing and waterproof properties are of great significance for the stable operation of the power system. However, due to various reasons, the cable corridor may leak and need to be plugged in time. This article will introduce several common methods of plugging leaks in cable corridors.
Pay attention to the direct communication here, 24 hours dedicated to your service.
1. Sealant plugging.
Sealant is a material commonly used in cable corridor leakage, which has the characteristics of good sealing, strong waterproofness and aging resistance. When plugging leaks, you can apply sealant to the leaking area and wait for it to dry to achieve the plugging effect. It is important to note that the sealant should be applied evenly to avoid bubbles or cracks.
2. Rapid plugging agent plugging.
Rapid plugging agent is a fast-setting material that can plug a leak in a short period of time. When plugging leaks, it is necessary to mix the rapid plugging agent according to the proportion on the instructions, and then apply it to the leakage part and wait for it to solidify. It should be noted that the solidification time of the rapid plugging agent is short, and it is necessary to grasp the timing of application.
3. Waterproof mortar plugging.
Waterproofing mortar is a type of mortar with waterproof properties that can form a waterproof layer on the surface of a concrete structure. In the leakage part of the cable corridor, waterproof mortar can be used to plug the leakage. Before construction, it is necessary to clean up the leakage part, and then mix the waterproof mortar according to the proportion on the manual, apply it to the leakage part, and wait for it to dry to achieve the plugging effect.
Fourth, grouting plugging.
Grouting plugging is a method of plugging leaks by injecting slurry into the leaking area. In the leakage part of the cable corridor, the leakage can be plugged by grouting plugging method. Before construction, it is necessary to clean up the leaking part, and then use a grouting machine to inject the prepared slurry into the leaking part and wait for it to solidify. It should be noted that grouting plugging requires a professional construction team to operate to ensure the quality of construction.
5. Replace the sealing material.
If the sealing material of the cable corridor is aged or severely damaged, it needs to be replaced with a new sealing material in time. When replacing the sealing material, the original sealing material needs to be cleaned and the new sealing material installed as required. It should be noted that the replacement of sealing materials requires a professional construction team to operate to ensure the quality of construction.
6. Strengthen daily maintenance.
In order to avoid water leakage in the cable corridor, routine maintenance work needs to be strengthened. Regularly inspect the sealing of the cable corridor, and find and deal with water leaks in time. At the same time, it is necessary to pay attention to the waterproof measures of the cable corridor to avoid damage to the cable corridor caused by rain and snow.
In short, there are many ways to plug leaks in cable corridors, and it is necessary to choose the appropriate plugging method according to the specific situation. Sufficient preparation is required before construction, and attention needs to be paid to construction quality and safety during the construction process. Only by choosing the appropriate plugging method and strengthening the daily maintenance work can the stable operation of the power system be guaranteed.
