Self-reinforced anti-seepage outer wall

Abstract

The invention discloses a self-reinforced anti-seepage outer wall, and belongs to the field of buildings. The self-reinforced anti-seepage outer wall comprises two waterproof layers and a concrete layer fixedly poured between the two waterproof layers. After self-solidification balls embedded in the concrete layer are used for a long time, the waterproofness of the outer wall is reduced, and at the moment, the outer wall is gradually degraded; when water seepage occurs, water vapor gradually enters a hollow through rod to gradually dissolve water-soluble columns, so that the limiting effect ofthe water-soluble columns on an elastic film is gradually weakened, at the moment, the elastic film is extruded and broken under the extrusion effect of water in a water storage self-expansion layer,and the remaining water-soluble columns are added and dissolved; and meanwhile, after the water-soluble columns are dissolved, the two ends of the hollow through rod are through, so that water makescontact with lime powder and solidifies the lime powder, the effect of fixed-point strength compensation of the water seepage position is achieved, the overall strength of the outer wall is effectively improved, large potential safety hazards caused by water seepage of the outer wall are not prone to happening, and safety is improved.

Description

technical field [0001] The invention relates to the field of construction, and more specifically relates to a self-reinforcing anti-seepage exterior wall. Background technique [0002] Defined by the judgment method, let A-B be a wall, if the A-B wall line can cut the relevant enclosure structure, it is an inner wall, otherwise, it is an outer wall. From an architectural point of view, the enclosure of a building to form an indoor and outdoor boundary component is called an exterior wall. Its functions are: bear a certain load, shelter from wind and rain, thermal insulation, noise prevention, fire safety, etc. The waterproofing of building exterior walls should have the basic function of preventing rainwater and snowwater from intruding into the wall, and should have the properties of anti-freezing and thawing, high and low temperature resistance, and wind load. In order to ensure the firmness and durability of the wall, moisture-proof and waterproof measures should be tak...

Problems solved by technology

[0003] Conventional concrete is made by mixing cement, gravel, sand and water in proportion. In the water seepage environment, the fine particles in the concrete solidification period are easy to rinse and lose the slurry. After curing, there are many pores. Poor waterproof performance; concrete buildings and water soaked in water for a long time require concrete to have a certain degree of waterproof and impermeability, such as the construction of deep mines, the shaft concrete function, because it passes through complex geology and many aquifers, the anti-seepage water of the project is the first choice for mines at home and abroad. It is a recognized technical problem in the construction industry; another example is that there are concrete waterproofing problems in reservoir dams, highways, railway tunnels, and subways; the current solution to concrete water seepage is mainly to add waterproofing agents, but the formula of waterproofing agents is unreasonable. Unsatisfactory, therefore, the surface of the existing concrete buildings seeps and falls off, the service life is short, the repair construction is difficult, the operation is complicated, and the cost is high

[0004] Although the existing concrete structure has certain crack resistance and impermeability, after a long time of use, the strength of the concrete structure will gradually decay, and water seepage will easily occur inside it. When it is wet, it is prone to cracks, and when the situation is serious, it may even cause partial pulverization of the wall, which will affect the overall strength of the wall and pose a great safety hazard
