The current problem of waterproof sealing for cable ducts passing through walls in underground distribution rooms in residential areas is becoming increasingly serious. Traditional sealing products such as sandbags, fireproof mud, and cement cannot meet the needs of residential user units, and the sealing effect of traditional sealing products is average, with a service life of generally 1 to 2 years. Some even need to be replaced within a shorter period of time, Hangzhou Hengma Power Technology Co., Ltd. has invented an inflatable pipeline sealing device that can effectively solve the problem of sealing effect and sealing time, providing a perfect solution for community users. This picture shows the situation of a Beijing company using traditional sealing products before using inflatable pipeline sealing products. According to the relevant needs of the sealing user and the sealing construction party in the community, sealing has become a serious problem, and the sealing effect cannot meet the requirements. After the sealing is completed, there may be water seepage in the pipeline, and the sealing position is not very beautiful, especially for the sealing of multiple pipelines, which basically cannot meet the sealing and waterproofing requirements, And after the sealing is completed, it needs to be filled for a long time, which is not easy to remove and affects later maintenance and construction. This picture shows the effect of using Hangzhou Hengma inflatable pipeline sealing. After the sealing is completed, the acceptance party requested on-site testing for water seepage and resistance to water pressure. The acceptance party conducted an 8-meter water pressure injection, but no water leakage occurred. The inflatable sealing device did not flush out of the pipeline due to water pressure, and the sealing of multiple cables did not leak. The inflatable pipeline sealing device has received unanimous praise from many users for its effectiveness in sealing the underground distribution room in residential areas. There is no need to worry about safety hazards caused by water ingress into the distribution room. Moreover, the surface of the property construction company is convenient to install after construction, and there is no need to check for water leakage in the wall pipes for a long time. This has indeed solved their previous problem of water leakage, and we strongly recommend using products in surrounding residential areas.

According to the relevant needs of the community and the information provided by the community's blocking users and the blocking construction party, blocking has become a serious problem, and the blocking effect cannot meet the requirements. After the blocking is completed, there will still be water seepage in the pipeline, and the blocking position is not very beautiful, especially when multiple pipelines are blocked, which cannot meet the basic waterproof requirements for blocking. Moreover, after the blocking is completed, it needs to be filled for a long time, which is not easy to remove and affects later maintenance and construction.

After the sealing was completed, the acceptance party requested on-site testing for water seepage and anti water pressure issues. The acceptance party conducted an 8-meter water pressure injection, but no water leakage occurred. The inflatable sealing device did not flush out of the pipeline due to water pressure, and the sealing of multiple cables did not leak.
