Abstract

The invention discloses a JX waterproof anti-crack concrete construction method. The JX waterproof anti-crack concrete construction method is characterized by comprising the following steps that construction preparation is carried out; template and steel bar engineering construction installation is carried out; embedded piece installation is carried out; installation is carried out according to the type, number and position requirement of embedded pieces; a template supporting system, steel bar engineering and the embedded pieces are installed and checked and accepted; JX waterproof anti-crackconcrete is poured; and maintenance and detection are carried out. According to the JX waterproof anti-crack concrete construction method, structural self-waterproofing is taken as the principal thing, flexible waterproofing is taken as the secondary thing, the excellent performance of JX novel materials is used for greatly improving the waterproof anti-crack performance of the concrete, the service life of a concrete structure is prolonged, and the purpose of effectively improving the economic benefit and the social benefit is achieved.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a construction method of JX waterproof and crack-resistant concrete. Background technique [0002] At present, concrete structures with high waterproof and crack resistance requirements such as basements, roofs, and pools, due to improper selection of waterproof and crack resistance design, construction technology, and construction materials, have problems such as leakage and cracks after construction, which affects the durability of concrete structures. . In order to effectively solve this problem, the self-waterproofing of the structure is adopted as the main method, and the flexible waterproofing is supplemented, and the excellent performance of JX new material is applied to greatly improve the waterproof and crack resistance of concrete. Contents of the invention [0003] The object of the present invention is to provide a kind of JX waterproof...
