Description

[Technical field]

[0001] The utility model relates to the field of building engineering construction, in particular to an electric penetration repair device for a basement concrete structure. [Background technology]

[0002] Basement leakage is a major problem in modern buildings. Most buildings are now reinforced concrete structures. Once the concrete cracks, the water that enters will not only penetrate into the room. What is more serious is that the water will corrode the steel bars inside the concrete, which will have a very serious impact on the entire building structure. The worst result is that the bearing capacity of the building is greatly reduced. Therefore, the waterproofing of the basement during use is a very serious problem. Basement water seepage is a very serious problem and the cost of repair is very high.

[0003] When a basement leaks, first of all, it is necessary to determine the source of the leak, which may come from structural cracks, construction joints, damaged waterproof layers, or drainage system problems. Before repairing, clean the leaking area, remove loose concrete, mortar, or old waterproof materials, and ensure that the repair surface is dry and clean. Then use grouting and injection construction methods to inject epoxy resin or polyurethane materials to fill the structural cracks. These traditional grouting methods have great damage to the concrete structure and cannot fill and repair smaller cracks, resulting in incomplete repairs, easy to leak again, and short effective anti-seepage time. [Summary of the invention]

[0004] The technical problem to be solved by the utility model is to provide an electric osmosis repair device for a basement concrete structure, which combines electric osmosis and osmotic crystallization materials to realize active repair of cracks in the basement concrete structure, has good repair effect and strong compactness, and can also inhibit the corrosion of steel bars inside the concrete structure.

[0005] The utility model is achieved in this way:

[0006] An electric osmosis repair device for a basement concrete structure, the electric osmosis repair device comprising a positive wire, a negative rod, an electric osmosis control system and a permeable crystallization material layer, the positive wire is evenly buried inside the basement concrete wall panel, the negative rod is vertically buried in the outdoor soil of the basement, and the vertical distance from the positive wire is 3-5m; the positive wire and the negative rod are electrically connected to the electric osmosis control system; the permeable crystallization material layer is brushed on the inner surface of the basement concrete wall panel, and the thickness is 1-2mm.

[0007] Furthermore, the positive electrode wire is buried in the basement concrete wall to a depth of 1-2 cm.

[0008] Furthermore, there are a plurality of negative electrode rods, and each of the negative electrode rods is located at a corner of the basement.

[0009] Furthermore, the electrical infiltration repair device also includes a humidity sensor, which is arranged on the inner surface of the basement concrete wall panel and is electrically connected to the electrical infiltration control system.

[0010] The utility model has the following advantages:

[0011] The utility model utilizes the electric field formed between the positive electrode wire and the negative electrode rod, and utilizes the principle of electroosmosis, that is, the polarity of water molecules makes it easy for them to combine with the cations dissolved in the concrete pore fluid to form hydrated cations, and produce a directional arrangement under the action of the external electric field. The ions migrate under the action of the electric field, and drag the surrounding polar water molecules to move together. The essence of electroosmosis is the migration of water molecules dragged by ions under the action of the electric field. Then, water spraying maintenance is carried out regularly to allow the components of the infiltrated crystallization material layer to migrate to the interior of the concrete for repair, thereby improving the compactness and pH value of the concrete, and also inhibiting the corrosion of concrete steel bars, and improving the long-term stability of the concrete structure.

[0024] 3d carbonization test:

[0025] The ratio of water to powder in the raw materials of the infiltration crystallization material layer is 1.0.

[0026] Comparative Example 1:
