Width measuring and repairing device for preventing and treating mass concrete cracks and operation method

Abstract

The invention discloses a width measuring and repairing device for preventing and treating mass concrete cracks and an operation method. The width measuring and repairing device comprises a vehicle body, wherein a sleeve is fixedly connected to the inner part of the vehicle body in a penetrating manner; a vertical cylinder is fixedly connected to the inner part of the sleeve in a penetrating manner; and a repairing mechanism is arranged in the vertical cylinder. According to the width measuring and repairing device for preventing and treating mass concrete cracks disclosed by the invention, the control of a grouting range and a grouting amount is realized through the size of the staggered area of a through hole and an opening in the bottom of the vertical cylinder, so that the repairing accuracy is improved, and the width measuring and repairing device is suitable for cracks of different sizes; besides, waste can be avoided; during expansion, after grouting is performed at the cracks, the width measuring and repairing device can have the effect of scraping flatly, so that the repairing flatness is improved; scale lines are arranged, so that the width of the cracks can be measured through comparing a scraping plate with the width of the cracks; after grouting is performed at the cracks, rolling can be performed, so that the repairing compactness is improved, and the repairing quality is improved; and the width measuring and repairing device has the effect of stirring slurry, so that the slurry is prevented from solidifying, the quality of the slurry is improved, and the repairing effect is further improved.

Description

technical field [0001] The invention relates to the technical field of concrete crack repairing devices, in particular to a width measuring repairing device and an operation method for preventing and controlling large-volume concrete cracks. Background technique [0002] During the concrete pouring process, due to temperature control, concrete ratio, pouring speed, concrete mixing and other issues, cracks with different depths and openings often appear. Concrete cracks not only affect the appearance quality, but also have a great impact on the safety of concrete structures. Therefore, cracks need to be repaired, and most of the methods used are grouting. [0003] The large-volume concrete crack repairing device in the prior art cannot control the grouting range and the grouting amount when in use, thereby affecting the repairing accuracy. It is not suitable for cracks of different sizes, and it is easy to cause waste. After grouting, it cannot be scraped and flattened, whic...

Problems solved by technology

[0003] The large-volume concrete crack repairing device in the prior art cannot control the grouting range and the grouting amount when in use, thereby affecting the repairing accuracy. It is not suitable for cracks of different sizes, and it is easy to cause waste. After grouting, it cannot be scraped and flattened, which affects the flatness of the repair, and the width of the crack is measured. After grouting at the crack, it cannot be rolled, resulting in low repair density, affecting the quality of the repair, and the slurry is easy to solidify. Reduced slurry quality, further reducing repair effectiveness
