Description

Technical Field

[0001] This utility model relates to the field of large-volume concrete repair technology, and in particular to a device for drilling deep microcracks in large-volume concrete structures during their service life. Background Technology

[0002] Large-volume concrete, due to its thickness and size, is prone to internal temperature rise, leading to thermal stress. These thermal stresses are particularly significant during the early hardening process of concrete, when its tensile strength is still low. When this stress exceeds the tensile strength of the concrete, cracks will form. Furthermore, concrete will also crack due to shrinkage during the drying process. These cracks may be negligible initially, but over time they can gradually expand, even penetrating the entire structure, severely impacting the durability and safety of the concrete structure. Therefore, timely and effective measures must be taken to reinforce and repair large-volume concrete structures that develop cracks during their service life.

[0003] Existing techniques for repairing cracks that appear in large-volume concrete during service life are as follows: First, clean and mark the direction and location of the cracks; second, cut a "V" shaped groove along the crack, clean loose and carbonized concrete, and keep the groove dry; then, apply a cement-based penetrating crystalline material, and seal with polysulfide building sealant and non-curing rubber sealant. For cracks wider than 0.1 mm, drilling and grouting are required. The length and diameter of the grouting needle are selected according to the crack depth, and the drilling depth is determined through classification to ensure sealing effectiveness. Finally, through a series of treatment measures, the cracks are effectively sealed, improving the durability and safety of the concrete structure.

[0004] Patent document CN220336835U discloses a drilling and hole-forming device. The device includes: a drilling machine; a cleaning system connected to the drilling machine for cleaning debris generated during drilling operations; and a working platform equipped with an adjustable support mechanism for adjusting the horizontal position of the drilling machine. A guide mechanism connected to the drilling machine is located at the top of the working platform to limit the movement trajectory of the drilling machine. This invention addresses the shortcomings of existing drilling equipment that is unsuitable for confined spaces or steep slopes, enabling horizontal adjustment based on the actual working location.

[0005] As in the prior art of the aforementioned patent, during the concrete drilling process, the device generates a large amount of dust around the hole drilled by the drill bit. This dust not only permeates the air, reducing visibility at the work site, but also has a significant impact on the environment and drilling work. The fine particles in the dust are easily inhaled by workers, posing a threat to their respiratory health. Long-term exposure may even lead to occupational diseases. At the same time, the dust adheres to the drilling equipment, accelerating its wear and affecting the accuracy and efficiency of drilling. In addition, the dust may also pollute the surrounding environment and damage the ecosystem. Utility Model Content
