[0069]

[0070] (2) Improve safety performance

[0071] Manual grinding with a grinder: Grinding is a hot work, which is noisy and may cause injury due to unskilled or incorrect use of the grinder.

[0072] Manual grinding with a polishing machine: The demand for grinding is large, but the grinding efficiency is low, and the problem of rushing work will increase safety hazards;

[0073] Square steel pipe sealing plate grinding and zinc removal device: There is no sharp noise during grinding, no need to use a grinder, simple operation and automatic grinding, no problem of injury caused by incorrect use of the equipment;

[0074] Square steel pipe sealing plate grinding and zinc removal device: The grinding efficiency is significantly improved, there is no need to worry about the large demand for grinding, and there will be no chaos due to busyness.

[0075] (3) Improve construction quality

[0076] Manual grinding method of polishing machine: the quality of sealing plate grinding depends on the operator's personal experience and technique, and it is impossible to maintain a uniform standard. In addition, the force during grinding is often not uniform, resulting in uneven grinding thickness of the sealing plate. Novices may have rework problems due to poor grinding.

[0077] Square steel tube sealing plate grinding and zinc removal device: it realizes automation, and the grinding quality will not be affected by novice operation. The sealing plates basically polished by the machine are of the same standard, that is, the grinding area and thickness of the sealing plates are basically the same.

[0078] The use of square steel tube sealing plate grinding and zinc removal device for sealing plate grinding can effectively improve work efficiency and work quality, and at the same time can well avoid safety hazards in grinding operations. Through the analysis of the construction volume, the use of new equipment for grinding operations, taking Taipingling Phase I as an example, completing the sealing plate grinding of the entire Taipingling Phase I can save 34.30 man-months of manpower investment. If it is promoted and used in subsequent projects, the overall benefits will be doubled.
