Description

Technical Field

[0001] The utility model relates to the technical field of grouting machines, and particularly relates to an integrated stirring grouting machine for building expansion joints. Background Art

[0002] With the rapid development of China's construction industry, buildings need to adapt to deformations caused by temperature changes, internal stress changes in structures, uneven settlement of foundations, earthquakes, etc. Usually, expansion joints are set at corresponding intervals in buildings to avoid damage to building structures due to deformation, which is of great significance for the safe operation of buildings. Leakage of expansion joints is a common problem in construction projects. The defect of expansion joint leakage needs to be specifically treated by pouring grouting materials into the expansion joints through a pressure grouting machine. The grouting materials need to be proportioned and stirred before being poured to the corresponding positions.

[0003] Existing pressure grouting machines are pure grouting equipment without stirring equipment, and construction workers need to independently set up stirrers. This method has problems such as low efficiency, troublesome operation, uneven stirring, and potential safety hazards. Therefore, we provide an integrated stirring grouting machine for building expansion joints. Content of the Utility Model
