The problems of moisture resistance, corrosion resistance and corrosion resistance of the basement wall structure are solved, the building structure can be protected, and the living comfort is improved.
The main sources of basement moisture and water seepage are two aspects: gaseous water in the air or condensed water generated by the intersection of cold air and hot air; the water in the soil outside the building permeates, and the underground structure is buried in the soil, receives the influence of groundwater, and the performance of material has already declined, although the waterproof layer has been laid to the wall body outside, and the anti slow infiltration, traditional waterproof mode is not ideal, and waterproofing membrane usually is organic material, and it can receive biological action at the structure surface and produce damage and damage. Once the material ages, microcracks develop and the waterproofing effect is lost. Meanwhile, concrete is a non-homogeneous brittle material and belongs to a porous structure in a microstructure view. The characteristics of the porous material determine the important influence of the pores on its permeability. Moisture is generated in the foundation and the wall of the building because of being closely related to the capillary force inside the concrete structure. Water can permeate into the structure through pores, microcracks and other modes by utilizing the self-weight, the micropore potential energy ratio of the pores is larger than the gravitational potential energy, and the smaller the pore diameter of the pores is, the more obvious the water seepage is. And when water evaporation exists, the surface tension of the capillary in the pores changes, so that shrinkage cracks of the capillary are caused, and after continuous shrinkage is limited, cracks generated due to other reasons (thermal shrinkage, chemical shrinkage and carbonization shrinkage) can be further expanded, so that the poor working conditions of water seepage, warping and the like of the bottom wall and the foundation surface of the building are caused.
At present, the electroosmosis technology is adopted in the prior art to solve the water seepage problem of the concrete structure, but the electroosmosis technology is only used or a waterproof agent is only used on the surface of the repair structure to carry out a waterproof mode, so that the internal cracks and pores of the repair structure are difficult to carry out completely-permeated in-situ improvement treatment, the water flow in the building structure is not completely prevented, and the building structure has high water absorption.
