Description

Technical Field

[0001] The utility model relates to the technical field of building waterproof engineering, in particular to an expansion joint leakage repairing device used in building waterproof engineering. Background Art

[0002] A building expansion joint is a structural joint set at an appropriate position along the construction joint direction of a building or structure to prevent cracks or damage to the structure due to climate temperature changes (thermal expansion and contraction). The expansion joint is exposed to rainwater erosion for a long time, which can easily cause the reinforced concrete between the expansion joints to be corroded by rainwater. Therefore, the inside of the expansion joint needs to be grouted and leak-proof.

[0003] After searching, a utility model with publication number CN218438414U specifically discloses an expansion joint leak-proof device used in building waterproofing projects, including a trolley located above the expansion joint and a grouting pipe body, straight rods are provided on the left and right sides of the trolley, one end of the straight rod passes through the interior of the trolley and is fixed with a splint, the straight rod is movably connected to the penetration point of the trolley, the surface of the straight rod is sleeved with a spring, the spring is located between the inner wall of the trolley and the splint, a number of partitions are installed on the left and right sides of the surface of the grouting pipe body, a motor is fixedly installed at the bottom of the inner cavity of the trolley, and the output shaft of the motor is fixedly connected to the first gear; the utility model can fix the pipe used for grouting and can also clean the outer surface of the bottom end of the grouting pipe, which solves the problem that the current leak-proof device easily sprays asphalt slurry to the outside of the expansion joint and the outer surface of the bottom end of the grouting pipe easily adheres to the asphalt slurry.

[0004] Although the above patent can fix the grouting pipe and clean the outer surface of the bottom end of the grouting pipe, it solves the problem that the current leak-proof device easily sprays asphalt slurry to the outside of the expansion joint and the outer surface of the bottom end of the grouting pipe easily adheres to the asphalt slurry. However, when the existing expansion joint leak-proof device uses an irrigation pipe to repair the expansion joint position, the irrigation pipe is large in size and is not convenient to insert into the expansion joint. The structure inside the expansion joint is relatively complex, and its internal structure has a certain arc shape, which results in the irrigation pipe being used to repair the expansion joint. It is not convenient to spray concrete mud deep into the expansion joint, thereby affecting the repair quality of the expansion joint.

[0005] Therefore, it is necessary for us to propose a building waterproofing project using an expansion joint leak repair device to solve the above problems. Utility Model Content
