盾构机新型尾盾注浆块改进浅析

New Shield Machine Tail Shield Grouting Block

通过对目前的盾构机尾盾注浆块进行分析,阐述了其在结构和工艺流程上存在的缺点:加工周期长、成本高、效率低。在此基础上,改进了注浆孔的结构和工艺流程:由长圆形注浆孔改成长方柱体注浆孔,由对半加工改成整体加工。

In this paper, through the analysis of the currentshield machine tail shield grouting block, the shortcomings in thestructure and process flow are described： long processing cycle,high cost and low efficiency. On this basis, we have improved thestructure and process of the grouting hole： the elliptical groutinghole is changed into the square grouting hole, which is changedfrom semi-machining to integral machining.
