Historical building foundation and ground floor wall infiltration moisture protection system and method

Abstract

The invention provides a historical building foundation and ground floor wall infiltration moisture protection system. A ground floor wall comprises a wall part extending into a soil layer and a wallpart getting close to the ground surface. Underground water is likely to infiltrate into the wall parts and a foundation, and the phenomena of moisture and erosion are more likely to occur. The protection system is mainly used for conducting infiltration type moisture prevention treatment on the foundation and a ground floor wall body. One side of the ground floor wall body of a historical building is provided with a vacuum cavity communicating with the ground floor wall body in the extending direction of the ground floor wall body. A vacuum pumping device is connected to the vacuum cavity. The other side of the ground floor wall body of the historical building is provided with a plurality of liquid injection systems in the extending direction of the ground floor wall body. The liquid injection systems are used for injecting a hydrophobic material solution into the foundation and the ground floor wall body. Through the protection system, hydrophobic films are formed on the inner surfaces of bricks and mortar holes of the foundation and the ground floor wall body of the historical building and the inner surfaces of the soil nearby the foundation to achieve the non-infiltration effect. Accordingly, the waterproofness of the foundation and the ground floor wall body of the historical building is improved.

Description

technical field [0001] The invention belongs to the technical field of historical building protection, and in particular relates to a permeable moisture-proof system and a moisture-proof method for foundations and bottom walls of historical buildings. Background technique [0002] Historical architectural relics are an important part of our country's cultural relics, and masonry architectural relics are the main part of historical architectural relics. With the development of history, typical buildings constructed during the Republic of China gradually entered the scope of protection. The state allocates a large amount of funds for the repair of such historical buildings every year, hoping to achieve the purpose of moisture-proof, anti-corrosion, and anti-corrosion of the walls. This can not only protect these historical buildings, but also in the process of using these historical buildings for offices more comfortable. However, cultural protection experts mostly graduated ...

AI Technical Summary

Problems solved by technology

[0006] The present invention aims at the protection of historical buildings in the prior art by building a layer of hydrophobic chemical materials on the surface of the wall and cannot prevent moisture and corrosion, and provides a permeable moisture-proof system for the foundation and bottom walls of historical buildings. The inner surface of the brick and mortar pores of the foundation and the underlying wall and the inner surface of the pores of the soil near the foundation form a hydrophobic film to achieve the purpose of imperviousness, and then achieve the purpose of improving the waterproofness of the historical building foundation and the underlying wall
