本欧洲标准与第1部分一起处理了地下连续墙设备的所有重大危险，当其按预期使用时，以及在制造商可合理预见的与机器整个使用寿命相关的误用情况下（见第4条）。 本部分的要求是对EN 16228-1:2014+A1:2021中制定的通用要求的补充。 本文件不重复EN 16228-1:2014+A1:2021中的要求，但增加或取代了地下连续墙设备的应用要求。

This European Standard, together with part 1, deals with all significant hazards for diaphragm walling equipment when they are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer associated with the whole life time of the machine (see Clause 4). The requirements of this part are complementary to the common requirements formulated in EN 16228-1:2014+A1:2021. This document does not repeat the requirements from EN 16228-1:2014+A1:2021, but adds or replaces the requirements for application for diaphragm walling equipment.
