Concrete self-waterproof structure of residential building underground engineering, and construction method of concrete self-waterproof structure

Abstract

The invention discloses a concrete self-waterproof structure of residential building underground engineering, and a construction method of the concrete self-waterproof structure. The construction method comprises the following steps that the segmented pouring length is selected according to the structure type; according to environmental climates and temperature characteristics of different seasons, the components and the mixing amount of a composite high-performance concrete anti-cracking agent are selected reasonably; the concrete mix proportion is optimally designed according to the characteristics of local concrete raw materials; a strainmeter is buried before pouring; the reasonable construction sequence, the vibration method and the surface finishing method are adopted; and the reasonable formwork removing time and a reasonable curing system are adopted according to the temperature measuring result. According to the concrete self-waterproof structure, a set of perfect self-waterproof system is formed in the aspects of the segmented pouring length, model selection of the anti-cracking agent, the concrete mix proportion, data monitoring, field construction technical disclosure and the curing system, concrete shrinkage cracks can be effectively controlled, and the self-waterproof effect of the concrete structure is achieved.

Description

technical field [0001] The invention belongs to the technical field of self-waterproof concrete, and in particular relates to a concrete self-waterproof structure for underground engineering of residential buildings and a construction method thereof. Background technique [0002] According to statistics, at present, 65% of the buildings in China will have different degrees of leakage within 1 to 2 years of being put into use; leakage problems account for 65% of real estate quality complaints; After 8 years, different degrees of renovation and maintenance are also required. [0003] There are certain misunderstandings in the waterproofing of traditional concrete structures. They only pay attention to the impermeability index of concrete, while ignoring the control of harmful cracks in concrete. One point of the concrete structure has waterproof ability. If there is a crack on one surface of the concrete structure, no matter how high the impermeability level of a single point...

Problems solved by technology

However, this patent does not select different concrete anti-cracking agents for seasonal changes, nor does it adjust the form removal and maintenance system according to the seasons. If this method is used in construction conditions with large temperature changes, it will not only affect the construction efficiency, but also difficult to avoid construction. post-crack generation
