Recently, Jiagushi again spread good news, the application of "a building wall long-term alkali anti-seepage structure" and "a concrete reservoir open water leakage back water maintenance structure" two utility model patents passed the review and approved by the State Intellectual Property Office, authorized, patent number is: ZL 2021 2 0867323.6 and ZL 2021 2 1754913.4.

A long-term alkali anti-resistant structure of building wall

In the toilet exterior wall around the building, the exterior wall, the floor and the wall corner junction, because the long-term wet water or water layer failure causes leakage, the water-soluble components in the material migrate to the surface with the capillary hole, thus the problem of alkali ubiquity in the wall, and it is difficult to completely eliminate.

The conventional treatment method of wall alkali is acid, such as acetic acid and oxalic acid, but pickling can only temporarily solve the problem, the great probability of secondary alkali; acid has a strong corrosion effect on the wall, will cause damage; the wall decoration taste is great, professional operation tools must be worn, affect the construction efficiency.

The technical problem mainly solved by the utility model is to provide a long-term alkali removal and anti-seepage structure of the building wall, where alkali removal layer, concrete capillary sealant layer, retarding water nonleakage layer, polymer anti-alkali bonding paste, and polymer anti-alkali fiber cloth are successively arranged on the wall and leveling layer.

This structure through the cooperation of various materials, concrete capillary sealant block pores and dense concrete, fundamentally block the pan-alkali channel; coagulation water leakage and polymer anti-alkali fiber cloth through polymer anti-alkali bonding paste, with strong deformation ability, combined application, complement each other, from the source of alkali, fundamentally solve the problem of ubiqualkali and water resistance.

A maintenance structure of open water leakage of concrete reservoir

With the continuous development of China's construction industry, a large number of large-volume concrete reservoirs have been built successively. In the use of concrete reservoirs, leakage often occurs in different parts of the pool wall, mainly manifested as: wet surface, flow and hole water gushing.

Considering that the water maintenance of the reservoir is unchanged or affects the use, the back water maintenance is generally used.The traditional polymer mortar, epoxy and other materials maintenance, poor durability, and there will be a local bulge and debonding, leading to the overall damage of the repair layer and failure.

The utility model provides a clear water leakage back surface maintenance structure with the water surface in the tank and the surface of the tank to form a layer of water permeability and crystalline waterproof material. After water leakage and solidification, the polymer composite waterproof cloth is laid with epoxy adhesive.

The patent structure starts from the internal capillary pores of concrete, first dense the internal pores, and then combined with water leakage, polymer composite waterproof fiber cloth, with multiple actions to fundamentally solve the leakage problem of the concrete reservoir, improve the application cycle of the reservoir, and ensure the safety of the project operation.

Up to now, Jiagushi has applied for more than 70 + patents, 37 invention patents, of which 5 have been authorized, and 40 utility model patents (34 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.
