Concrete building wall crack bioremediation device

Abstract

The invention relates to the technical field of wall surface repair, and discloses a bioremediation device for concrete building wall cracks, which includes a housing, a rectangular opening is opened at the lower end of the housing, and a mounting plate is connected to the left inner wall of the housing through a connecting shaft for rotation and installation. The upper end of the plate is fixedly connected with a mounting block, one side of the mounting block is rotatably connected with a rotating shaft through the first rolling bearing, one end of the rotating shaft is fixedly connected with a cutting piece, and the other end of the rotating shaft passes through the first rolling bearing and is fixedly connected with the first bevel gear, The upper end of the mounting plate is fixedly connected with the first motor, and the output end of the first motor is fixedly connected with the second bevel gear, and the first bevel gear meshes with the second bevel gear. The bioremediation device for concrete building wall cracks can quickly tap the wall after slotting to find out whether there is hollowing on the wall, effectively improving the progress of the repair project, and can also blow the dust generated during cutting away from the slot tool Nearby, it is convenient for construction workers to slot.

Description

technical field [0001] The invention relates to the technical field of wall repair, in particular to a biological repair device for concrete building wall cracks. Background technique [0002] Cracks on the wall surface are caused by shrinkage caused by dehydration of concrete during the hardening process of concrete, or uneven expansion and contraction caused by the influence of temperature difference. Concrete crack repair refers to the use of scientific methods to repair concrete cracks. The technology is also called bioremediation. At present, the conventional methods of repairing concrete cracks generally include three methods: low-pressure glue injection repair, high-pressure repair and slotting repair method. Among them, the slotting repair method can repair cracks more thoroughly and is often used by construction personnel, but In the process of grooving, the current tools are relatively simple. After grooving, it is necessary to manually tap the wall to determine wh...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a bioremediation device for concrete building wall cracks, which has fast slotting speed, and can quickly tap the wall after slotting to find out whether there is hollowing on the wall, and cut The dust generated during the process can be blown away from the grooving tool, which solves the problem that after grooving, it is necessary to manually tap the wall to judge whether there is hollowing on the wall near the crack pattern, which is slow and takes up a lot of repair time. Moreover, the dust generated during the grooving process diffuses around the grooving tool, which affects the construction personnel's control of the direction of the grooving tool.
