Description
Technical Field
The utility model relates to the technical field of engineering construction, in particular to a reinforced concrete cutting device.
Background
In the field of constructional engineering, with the acceleration of urban progress and the continuous promotion of infrastructure construction, underground pile foundations are increasingly widely used. However, in some cases, such as project changes, design adjustments, pile foundation disposal, etc., it is necessary to clean the subsurface pile foundation. In the past, the removal of subsurface pile foundations has relied primarily on some conventional methods and equipment. Among them, it is common to perform preliminary crushing treatment by using mechanical equipment such as a drilling machine, a crusher, and the like. The drilling machine is used for drilling holes in pile foundations through the rotary drill bit, but holes are formed only locally in the mode, and full cutting cannot be achieved. The crusher relies on strong impact force to crush concrete, but this method is liable to cause damage to peripheral structures and is poor in the treatment effect on reinforcing bars. In addition, there are simpler cutting tools, such as hand-held power saws or gas cutting devices. However, these tools are inconvenient to operate in confined underground spaces and have low cutting efficiency, and are difficult to handle for large-scale pile foundation cleaning tasks. For complex underground pile foundation structures, manual operations, such as auxiliary crushing by workers using tools such as pneumatic picks, are often combined. However, this approach is not only labor intensive, but also presents many security risks for personnel in the subsurface environment. In terms of technical principles, conventional mechanical devices are mostly based on simple mechanical actions, such as impact, drilling, cutting, etc., lacking systematic and comprehensive designs. In terms of control systems, it is also relatively crude and difficult to achieve accurate operation and control.
The above conventional methods have a number of significant disadvantages:
Firstly, the manual participation is high, which brings about great potential safety hazard in the underground construction environment. Underground spaces are usually narrow, dim, and have poor ventilation conditions, and there are various potential hazards such as collapse and water permeability. Workers work in such environments, and once accidents occur, rescue difficulties are extremely high, and serious casualties can be caused.
Second, the efficiency of manual operation is relatively low. Because of the limitation of manpower, the working time and the working strength are greatly restricted, so that the overall construction progress is slow, and the requirements of modern building engineering on efficient construction cannot be met.
Furthermore, the manual and mechanical means have a disadvantage in accuracy control. It is difficult to ensure that the cutting surface of the reinforced concrete is smooth and uniform, which not only affects the subsequent construction operation, but also can lead to waste of materials.
In addition, the existing cleaning mode has poor adaptability to different geological conditions and pile foundation structures. When encountering complex geological conditions or special pile foundation structures, the cleaning work is difficult to effectively, the construction scheme is required to be frequently adjusted, and the construction difficulty and cost are increased.
Therefore, a novel device is required to be developed aiming at the problems, the participation of manpower in underground construction is greatly reduced, the potential safety hazard is remarkably reduced, the efficiency of cleaning work is improved, the construction period is shortened, the requirements of engineering progress are met, meanwhile, the flatness and uniformity of a cutting surface can be ensured, the construction quality is improved, the material waste is reduced, the adaptability of equipment to various geological conditions and pile foundation structures is enhanced, and wider application is realized.
