凿井工程系属地下隐蔽工程,专业性强,工艺要求高,各道工序在技术上处理不好,往往造成塌孔、埋钻、井歪、井洞、断管、枯井等质量事故,一旦出现事故,一般导致全井报废,就会给企业带来很大经济损失。面临着建筑市场竞争激烈和地下水位不断下降的双重因素的威胁,要充分发挥机械化施工和开凿深井的优势,必须推行全面质量管理,加强技术经济指标的统计和分析,实行单井经济承包,按质分等奖惩,严格考核质量的经济价值,使工程质量不断提高,以质量求信誉,以质量求生存。
Sinking works are subterranean concealed projects, which are highly specialized and require high technological requirements. Each process is not well handled technically, often resulting in quality accidents such as hole collapse, buried drilling, well bores, wells, broken pipes, and dry wells. The occurrence of an accident generally leads to scrapping of the entire well, which will cause great economic losses to the company. Faced with the threat of two factors, namely the fierce competition in the construction market and the declining groundwater level, we must fully utilize the advantages of mechanized construction and drilling of deep wells. We must implement total quality management, strengthen statistics and analysis of technical and economic indicators, and implement single well economic contracting. Quality points such as rewards and penalties, strict assessment of the economic value of quality, so that the quality of the project continues to improve, quality and credibility, quality of survival.
