Wall moisture-proof system based on electroosmosis principle

Abstract

The invention belongs to the technical field of civil engineering wall maintenance, and particularly relates to a wall moisture-proof system based on an electroosmosis principle. The wall moisture-proof system comprises an electric field device and a chemical moisture-proof device, wherein the electric field device is composed of two electrodes matched with a power supply, and the two electrodes of the electric field device are arranged on the two sides of a wall; and the chemical moisture-proof device comprises a spraying mechanism used for jetting a hydrophobic agent, one end of the sprayingmechanism is connected with a raw material container used for containing the hydrophobic agent through a pipeline, the jetting range of the spraying mechanism is located between one electrode and thecorresponding wall side face, and the jetting direction of the spraying mechanism faces the wall side face. The wall moisture-proof system is simple in structure, internal cracks of a wall structureand pores of materials can be subjected to in-situ moisture-proof treatment, the hydrophobic effect of the wall is achieved from inside to outside, and damage caused by repeated infiltration of moisture into the wall is prevented.

Description

technical field [0001] The invention belongs to the technical problem of civil engineering wall body maintenance, and in particular relates to a wall body moisture-proof system based on the principle of electroosmosis. Background technique [0002] Engineering walls such as brick walls, brick-concrete walls, and concrete walls have the characteristics of large volume, complex environment, and immovability. Therefore, proper treatment of the structure against moisture, corrosion, and corrosion can not only protect the wall itself, but also improve its sense of comfort during use. There are two main sources of moisture and water seepage in the wall: gaseous water in the air, or condensed water produced by the intersection of hot and cold air; moisture infiltration from the soil outside the wall, especially underground wall structures such as basements or wall roots , because it is buried in the soil, it is greatly affected by groundwater. Although a waterproof layer will be ...

AI Technical Summary

Problems solved by technology

[0005] In the prior art, the use of electroosmotic technology has been disclosed to solve the problems of dampness and water seepage in the wall structure, but there are also great disadvantages, that is, the electroosmotic process needs to be carried out continuously, which not only consumes a lot of power, but also constitutes the electric field itself. The electrodes will also corrode quickly and lead to failure; at the same time, electroosmotic drainage itself is only a palliative solution to the problem, and it cannot perform in-situ improvement treatment for complete penetration of internal cracks and pores in the wall structure, resulting in no comprehensive prevention of water flow in the wall structure. The water discharged by electroosmosis will still be sucked back by the capillary of the wall, resulting in recurrence of dampness and water seepage
