在工业工程中,设备基础的预留孔留设问题是一个在工业工程中普遍存在而又难于施工的工程实际问题,特别是对于深度大、宽度小的狭长型预留孔的留设施工,一直是个难以解决的问题。对这一常见的问题下文针对兖矿三十七处承建的山东鲁南化肥厂双结构改造项目中的磨煤机基础施工进行了新的探讨分析,提出了一个新型的解决措施。 In industrial engineering, the problem of reserving reserved holes on the basis of equipment is a practical engineering problem which is ubiquitous and hard to be constructed in industrial engineering. Especially for the construction of large and narrow reserved holes with large depths, It has always been a difficult problem to solve. On this common issue, the following article explores and analyzes a new type of coal mill foundation construction in the double-structure reconstruction project of Shandong Lunan Fertilizer Plant contracted by 37 units of Yankuang and proposes a new type of solution.
