Method for repairing concrete cracks by adopting bacteria
The invention relates to a method for repairing concrete cracks by adopting bacteria, which comprises the following steps: culturing shewanella strains in a culture medium until the shewanella strains grow into bacterial colonies, and preparing shewanella suspension through the bacterial colonies; providing a cotton quilt, and laying the cotton quilt at the crack of the concrete; the shewanella bacterial suspension is evenly sprayed on the cotton quilt until the cotton quilt is completely wetted, and shewanella bacterial permeates into gaps of concrete through the cotton quilt; and water is sprayed on the cotton quilt at regular intervals until a biological membrane is formed on the surface of the concrete gap.
本发明涉及一种采用细菌修复混凝土裂纹的修复方法，包括如下步骤：于培养基内培养希瓦氏菌菌种，直至所述希瓦氏菌菌种成长为菌落，并通过所述菌落制成希瓦氏菌悬液；提供棉被，将所述棉被铺设于混凝土的裂缝处；于所述棉被上均匀喷洒所述希瓦氏菌悬液，直至所述棉被被完全湿润，所述希瓦氏菌通过所述棉被渗透至混凝土的缝隙内；定期于所述棉被上喷洒水，直至混凝土的缝隙表面形成生物膜。
