Rapid drilling system and drilling process for concrete deep crack detection

Abstract

A rapid drilling system for concrete deep crack detection is disclosed in the invention, and comprises a bottom plate, the top of the bottom plate is fixedly connected with a rectangular box, a dust collecting box and a water tank, the bottom of the bottom plate is fixedly connected with four supporting blocks which are symmetrical in pairs, and the interiors of the two supporting blocks located on the same side are rotationally connected with the same rotating shaft; wheels are fixedly connected to the two ends of the rotating shaft, a protection assembly used for preventing dust from leaking outwards is arranged at the bottom of the bottom plate, and an adjusting assembly used for adjusting the drilling angle is arranged in the rectangular box. The invention further discloses a drilling process. The system is simple in structure, movement of the device can be achieved through wheels, movement of the device is more convenient, the angle of a drill bit is adjusted through an adjusting assembly, the punching depth is controlled by rotating a second screw rod, and then a protection assembly is used for preventing dust from leaking to harm the body health of construction personnel; and dust is collected through a dust collection assembly and a dust falling assembly, and operation is easy.

Description

technical field [0001] The invention relates to the technical field of concrete crack detection, in particular to a rapid drilling system and a drilling process for detecting deep concrete cracks. Background technique [0002] Concrete cracks are the physical structure changes of concrete structures due to the action of internal and external factors, and cracks are the main reason for the reduction of the bearing capacity, durability and water resistance of concrete structures. The common treatment methods for concrete cracks include filling method, grouting method, structural Reinforcement method, concrete replacement method, electrochemical protection method, etc. [0003] Only by using the detection method to find out the cracks can the next step of filling the cracks be carried out. During the detection process, a drilling device is needed, but the existing drilling devices have the following defects: 1. It is not easy to move and difficult to carry; 2. There will be a ...

Problems solved by technology

[0003] Only by using the detection method to find out the cracks can the next step of filling the cracks be carried out. During the detection process, a drilling device is needed, but the existing drilling devices have the following defects: 1. It is not easy to move and difficult to carry; 2. There will be a lot of dust during the drilling process, and the long-term inhalation of dust by construction workers is harmful to health; 3. It is difficult to collect the dust during drilling; 4. The angle of the drill bit cannot be adjusted during drilling, and the depth of the drilling cannot be controlled. We propose a rapid drilling system and drilling process for detecting deep cracks in concrete to solve the above-mentioned problems
