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

Embodiment 1

[0044] see figure 1 , a crack-resistant concrete structure, including a prefabricated formwork 1, a concrete layer 2 is filled in the prefabricated formwork 1, and a plurality of randomly distributed multi-branched wires are embedded in the concrete layer 2, and the multi-branched wires include trunk wires 3 and multi-branched wires. A split wire 4, the multi-branched wires are longitudinally distributed in the concrete layer 2, so that the concrete exhibits tensile properties in the longitudinal direction, and at the same time, after accidental cracking, in the longitudinal direction, under the action of the multi-branched wires, it can show mutual involvement , not easy to crack further.

[0045] see figure 2 , there are pre-rupture points 5 connected between a plurality of branch wires 4 and trunk wires 3, and the number of branch wires 4 connected to each pre-break point 5 is 1-2, and the branch wires 4 and the trunk The drawing wires 3 are evenly distributed on the pre...

Abstract

The invention discloses a crack-resistant concrete structure and a construction method thereof, which belong to the field of concrete structures. A crack-resistant concrete structure and a construction method thereof can realize that when the concrete shows signs of cracking, the part close to the crack at the pre-cracking point will be less affected With a large force, the pre-cracking point near it breaks, so that the internal repair fluid can flow out, and then repair the cracks and bond the cracks, effectively inhibiting the further increase of the cracks. At the same time, under the action of multi-branch drawing, the concrete is The longitudinal direction exhibits the performance of tensile strength. After cracking, it can be intertwined in the longitudinal direction, which further plays a role in increasing the cracks. It is difficult to fall, and it will still be connected to the concrete structure, thereby effectively reducing the possibility of injuring workers due to cracked and falling concrete blocks, improving safety and effectively reducing potential safety hazards.

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, ...
