Abstract
Description
Technical Field
[0001] This utility model relates to the field of building structure technology, and more specifically, to a reinforced, waterproof and corrosion-resistant integrated concrete structure. Background Technology
[0002] Concrete structures are an important component of my country's construction projects, and their quality directly affects the safety of concrete buildings. In recent years, as the service life of concrete buildings in my country has generally reached or exceeded 20 years, higher requirements have been placed on the reinforcement, waterproofing, and anti-corrosion treatment of existing building concrete structures.
[0003] Currently, reinforcement, corrosion protection, and waterproofing of concrete structures in my country's construction projects typically employ single measures, making it difficult to achieve a synergistic, integrated solution. Existing technologies often focus on improving structural strength or providing only basic corrosion protection, while reinforced concrete still faces waterproofing failure due to deformation and cracking during later use. Summary of the Invention
[0004] The purpose of this invention is to solve the waterproofing problem caused by deformation and cracking in existing concrete structures in the later stages of use, and to provide a reinforced, waterproof and anti-corrosion integrated concrete structure to ensure the safety, structural strength and anti-corrosion and waterproof performance of the concrete structure, and extend the service life of the concrete structure.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A reinforced, waterproof, and corrosion-resistant integrated concrete structure includes a concrete body, with internal cracks filled with high-penetration epoxy resin slurry, and the damaged surface of the concrete body sequentially covered with a high-penetration epoxy resin layer and a cement mortar layer, and the entire surface of the concrete body is covered with a high-penetration epoxy resin coating, and a polyurea elastomer coating is fully covered on the high-penetration epoxy resin coating.
[0007] High-penetration epoxy resin slurry is used for repairing the concrete matrix; high-penetration epoxy resin layer and cement mortar layer are used for reinforcing the concrete structure; high-penetration epoxy resin coating is used for sealing the concrete interface; and polyurea elastomer coating is used for composite protection of the concrete matrix.
[0008] Furthermore, the high-penetration epoxy resin grout is injected under pressure into the cracks inside the concrete body.
[0009] Furthermore, the depth of the high-penetration epoxy resin slurry is 40% to 50% of the thickness of the concrete body.
[0010] Furthermore, the thickness of the high-penetration epoxy resin coating is less than or equal to 1 mm.
[0011] Furthermore, the thickness of the polyurea elastomer coating is greater than or equal to 1 mm.
[0012] Compared with existing technologies, this utility model integrates reinforcement, waterproofing, and corrosion protection for concrete structures. The internal cracks of the concrete body are filled with high-penetration epoxy resin slurry, and the surface of the concrete body is entirely covered with a high-penetration epoxy resin coating. The high-penetration epoxy resin coating is then fully covered with a polyurea elastomer coating, achieving a densification and reinforcement effect. This ensures integrated reinforcement, corrosion protection, and waterproofing, effectively addressing waterproofing problems caused by deformation and cracking in the later stages of concrete structure use, and preventing the risk of water seepage and leakage in concrete structures.

[0018] The following description, in conjunction with the accompanying drawings and specific embodiments, further illustrates the integrated reinforced, waterproof, and corrosion-resistant concrete structure of this utility model.
[0019] Please see Figure 1 This utility model discloses a reinforced, waterproof, and corrosion-resistant integrated concrete structure, including a concrete body 1, with internal cracks 2 of the concrete body 1 filled with a high-penetration epoxy resin grout 3. The high-penetration epoxy resin grout 3 is used for repairing the matrix of the concrete body 1, and is injected into the internal cracks 2 of the concrete body 1 under pressure.
[0020] High-penetration epoxy resin grout 3 was used to inject grout into the internal cracks of the concrete substrate 1. Through the dual effects of material penetration and consolidation, the structural strength of the concrete substrate 1 was significantly improved. During the reaction process, the high-penetration epoxy resin effectively penetrated into the honeycomb gaps and loose areas in the concrete substrate 1 through molecular chain growth and transformation, thereby achieving deep densification and reinforcement.
[0021] Please see Figure 1In this embodiment, the high-permeability epoxy resin grout 3 can be injected into the crack 2 inside the concrete body 1 through the water-stop needle 4. When injecting the high-permeability epoxy resin grout 3 through the water-stop needle 4, the needle spacing is 10cm-20cm, and the injection depth is 40%-50% of the thickness of the concrete body 1.
[0022] Please see Figure 2 The damaged surface layer 5 of the concrete body 1 is sequentially covered with a high-penetration epoxy resin layer 6 and a cement mortar layer 7. The high-penetration epoxy resin layer 6 and the cement mortar layer 7 are used for structural reinforcement of the concrete body 1. To repair the damaged surface layer 5 of the concrete body 1, the high-penetration epoxy resin layer 6 is first used for covering, and then the cement mortar layer 7 is used for repair.
[0023] Please see Figure 3 The surface of the concrete substrate 1 is entirely covered with a high-penetration epoxy resin coating 8, which serves as a sealant for the interface of the concrete substrate 1. A polyurea elastomer coating 9 is then applied over the high-penetration epoxy resin coating 8, providing composite protection for the concrete substrate 1 and preventing deformation cracking of the concrete structure in the later stages of service. In this embodiment, the thickness of the high-penetration epoxy resin coating 8 is less than or equal to 1 mm, and the thickness of the polyurea elastomer coating 9 is greater than or equal to 1 mm.
[0024] The construction process for a reinforced, waterproof, and corrosion-resistant integrated concrete structure includes: installing water-stop needles at cracks 2 or loose areas inside the concrete body 1, and injecting high-penetration epoxy resin grout 3; grinding the water-stop needles smooth after injecting the high-penetration epoxy resin grout 3; cleaning the damaged surface layer 5 of the concrete body 1, and sequentially applying a high-penetration epoxy resin layer 6 and a cement mortar layer 7 to the damaged surface layer 5 for filling, repair, and smoothing; applying a high-penetration epoxy resin coating 8 to the entire surface of the concrete body 1, and then applying a polyurea elastomer coating 9 over the high-penetration epoxy resin coating 8 to form a reinforced, corrosion-resistant, and waterproof integrated concrete structure.
[0025] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit disclosed in the present utility model should fall within the patent scope covered by the present utility model.
