Description

Underground waterproof system with same life cycle as building and construction method thereof

Technical Field

The invention belongs to the technical field of building engineering, and particularly relates to an underground waterproof system with the same life cycle as a building and a construction method thereof.

Background

The basement is an underground building, and the stability of the basement has important significance on the safety and the service life of the building. Because the basement is built underground, the waterproof performance of the basement directly influences the service condition of the basement and the whole service life of the building.

Building waterproofing is the measure taken from building materials and construction to prevent water from penetrating into some parts of the building. The waterproof is mostly used in roofs, underground buildings, underground parts of buildings, interior rooms and water storage structures which need to be waterproof, and the like. According to the different measures and means, the waterproof material is divided into two categories of material waterproofing and structural waterproofing. The waterproof material is formed by blocking the water passage by building materials so as to achieve the aim of waterproofing or increase the leakage resistance to reach the waterproof grade required by design, such as coiled material waterproofing, film waterproofing, waterproof concrete and waterproof mortar rigid waterproofing, clay and lime soil waterproofing and the like. The water-proof structure of the detail structure adopts a proper structural form to block the water passage so as to fulfill the aim of perfecting a water-proof system, such as a water stop belt, a water stop steel plate and the like. The flexible waterproof material includes, but is not limited to, waterproof roll material, waterproof paint and the like.

The rigid waterproof layer is made of waterproof concrete, waterproof mortar and other materials or is formed by doping a waterproof agent. In practical engineering applications, one of the ways is to adopt waterproof concrete as the engineering structure itself (using aggregate gradation to make the concrete compact or adding additives, or both). And the other is that a waterproof mortar surface layer doped with a waterproof agent is added on the surface of the structural layer. The domestic waterproof agent products have more types and are mainly used for improving the impermeability and the cracking resistance of concrete and reducing the shrinkage, but have the following defects: firstly, the ingredients of the products contain more chloride components, so that the steel bars are easy to corrode after the products are used, and the waterproof effect is not ideal; secondly, after the concrete is used, the shrinkage rate of the concrete is increased, and cracking is caused; thirdly, the powdery waterproof agent has a plurality of objective problems of large addition amount, poor dispersion performance and the like in the using process, so that the powdery waterproof agent cannot achieve the final waterproof effect.
