Recently, the utility model patent of "a repair of leakage structure of elevator well bottom plate" was approved by the State Intellectual Property Office. Patent No.: ZL 2021 2 1754761.8.

Due to geological subsidence, concrete cracking or waterproof layer damage and other reasons, there will often be groundwater leakage problems, serious areas will even have clear water emergence, this situation is generally complicated, a little attention will be the leakage.In view of the open water leakage on the bottom plate of the elevator shaft, most of the common solutions are the construction method of plugging before grouting, but when the traditional material treatment, although it can be temporarily blocked, but there will often be gel contraction, water dispersion, low durability, and the expensive price can not solve the open water leakage.

To solve the above technical problems, the utility model provides a maintenance plugging structure of open water leakage at the bottom of the elevator well, fill the cracks of quick condensate water leakage, and set grouting hole on one side, grouting submerged water, then build retarded water leakage, alkali waterproof fiber cloth, double component polymer mortar and rigid waterproof epoxy mortar.

Fast water can condense for a short time, which is the foundation of high liquidity, no dispersion in water, and high strength; stagnant water has excellent waterproof and bonding strength, waterproof can be used as leveling layer; two-component polymer mortar as a rigid waterproof protective layer, has excellent waterproof resistance and high water pressure; rigid waterproof epoxy mortar can effectively avoid water leakage risk caused by later cracking.A combination of materials are applied, complementing each other. The structural system formed has the technical advantages of not shrinking, not being scattered by bright water, has high durability characteristics, simple construction and low cost, and has good application value.

Up to now, Jiagushi has applied for more than 70 + patents and 37 invention patents, 5 of which have been authorized and 40 utility model patents (35 have been authorized).In the future, Jiagushi will forge ahead and pay more attention to scientific and technological innovation while forging ahead, so as to realize the transformation of more new technologies, new materials and new technology achievements, and boost the development of the industry to a new level.
