Crack-resistant concrete structure and construction method thereof

Abstract

The invention discloses a crack-resistant concrete structure and a construction method thereof, and belongs to the field of concrete structures. According to the crack-resistant concrete structure andthe construction method thereof, the situation that when concrete has signs of cracking, the parts, near cracks, of pre-fracture points can be subjected to relatively large force, and the adjacent pre-rupture points are broken can be realized, internal repair fluid conveniently flows out, then the cracks are repaired and bonded, and the further enlargement of the cracks is effectively suppressed;meanwhile, under the action of multi-branch drawing wires, concrete exhibits tensile properties in the longitudinal direction, after cracking, the concrete can show mutual drag in the longitudinal direction, and the role of enlarging the cracks is further played; and meanwhile, even if the concrete cracks are large, concrete fragments are generated, and under the action of the multi-branch drawing wires, the concrete fragments are difficult to fall and can still be connected to the crack-resistant concrete structure, so that the possibility of injuring workers due to fallen concrete blocks due to cracking is effectively reduced, the safety is improved, and the potential safety hazards are effectively reduced.

Description

technical field [0001] The invention relates to the field of concrete structures, in particular to a crack-resistant concrete structure and a construction method thereof. Background technique [0002] 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, ...

Problems solved by technology

[0002] 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 buildings made of concrete seeps and falls off, the service life is short, the repair construction is difficult, the operation is complicated, and the cost is high

[0003] However, although the existing concrete structure has a certain crack resistance, it is difficult to achieve the effect of suppressing the cracks after cracks occur, and as the cracks gradually increase, when cracks occur inside the concrete structure, serious , and even lead to the disintegration of the entire concrete structure, causing a great threat to safety. When the crack is at the edge, the cracked concrete block on the outside has the danger of falling and hurting pedestrians
