In daily life and industrial production activities, water leakage is often seen. If this situation were placed in the cable trench of the basement distribution room, the situation would only be worse. The impact on aesthetics is no longer a simple matter. Excessive water seepage can damage the wall structure or cause short circuits in various facilities in the distribution room, with unimaginable consequences. So, preventing leakage and blocking is the key, so how to deal with water leakage in the cable trench of the basement distribution room?Sealing at the bottom of the cabinetHow to do it?

　　Due to leakage, rainwater flows into and forms rainwater marks, causing water leakage in the cable trench of the basement distribution room. Some friends may ask, how can we better solve this problem? How to seal the bottom of the cabinet? If there is a problem, first analyze the cause of the problem. It is obvious that the leakage is caused by cracks, taking cable trenches as an example. If the treatment of construction joints during the tunnel pouring process does not meet the requirements of construction specifications, such as the construction joint should be at least 30cm away from the bottom plate, but the actual operation is that the construction joint and the bottom plate are in the same plane, which is not conducive to the treatment of the contact surface, and leakage will occur. For example, if there are cracks in the cable channel, even if the channel itself is long and no expansion joints are left, the foundation will still experience uneven settlement after the channel is built, resulting in cracks and leakage of the cable trench.

　　There is a saying that friends must remember, especially those in the power industry: cable trenches must be waterproof and sealed when entering the room from the outside, and the rest can be left without waterproof treatment, but drainage facilities should be left in appropriate positions. So we have already analyzed above that the cracks may be caused by human factors. We overlooked some details at the beginning, which resulted in water leakage in the cable trench later on. It may also be environmental factors. Due to years of neglect, the cable trench is slowly leaking water. No matter what the reason is, there must be a blocking mindset.

　　At this point, a new question arises: What should be done to seal the bottom of the cabinet? Two points: using appropriate materials and methods. Here is an overall cable waterproofing and leakage prevention construction plan. The materials used include: polymer expansion water lock (water absorption and fixation, rapid self-healing repair), flame-retardant sponge support network (effective water resistance, smoke resistance, and fire prevention), polymer cable pipeline leakage prevention and plugging agent (effective ingredients can quickly solidify to achieve plugging), YYA special waterproof and impermeable slurry, YY16 flash slurry (high strength, good waterproof and impermeable properties, and can strengthen the plugging effect). YY36 special weather resistant waterproof coating (with strong adhesion on the back surface, which can connect the steel pipe with the concrete base layer).
