Abstract

The invention provides an experimental device and method for repairing a film bag concrete crack by adopting vacuum grouting, the experimental device comprises a main body bearing frame, a sample fixing frame is supported and mounted on the top of the main body bearing frame, and a film bag concrete sample, a silica gel cushion layer and a vacuum cover are mounted on the sample fixing frame through a counter-force frame; a grouting hole, a suction hole and a measuring hole are formed in the vacuum cover; the grouting hole is connected with grouting equipment, and the suction hole is connected with vacuum suction equipment; and a vacuum pressure gauge is mounted on the measuring hole. The problems that in the film bag concrete crack repairing project, due to the fact that water vapor in cracks is not fully removed, slurry cannot enter the cracks, and small cracks are not filled, project damage is caused, and project durability is affected are solved. The device and the technology provided by the invention are simple and convenient to operate, and have wide engineering practical significance and application prospects.

Description

technical field [0001] The invention belongs to the technical field of membrane bag concrete crack repair experiments, in particular to an experimental device and method for repairing membrane bag concrete cracks by vacuum grouting. Background technique [0002] In recent years, with the development of basic engineering in our country, the number of port terminals and coastal water conservancy projects has increased; due to the advantages of convenient and fast construction, strong integrity, and good stability, membrane bag concrete has been widely used in engineering construction, especially in dams The overall quality of construction has been greatly improved in protection projects such as slope protection, bank protection, deep water bank protection, and bottom protection works, and plays a pivotal role in engineering protection. However, due to problems such as irregular construction and neglect of concrete maintenance work in the later period, irregular cracks occurred...
