通过对某道路及市政基础设施建设工程的实地测量和勘测，发现该工程地下水位较高，鉴于实际情况，对沟槽施工采用管井降水的施工方案，主要介绍了降水方案的工作原理、操作要求，以供同类工程参考借鉴。%Through the in-situ measurement and survey of the road and municipal facilities construction engineering,the paper finds out that the engineering underground water level is rather high. In light of the actual conditions,it applies tube well groove dewatering scheme,and mainly introduces its working principles and operation demands,with a view to provide some reference for similar engineering.
