盾构管片渗透检测仪

Duct piece infiltration detector for shields

Abstract

一种盾构管片渗透检测仪,弧形板下方设有支撑架,弧形板上设有进水孔,进水孔处连接水泵,待测管片置于弧形板的上方;弧形板与待测管片之间还设有密封框;所述密封框选用橡胶材质;所述水泵设有压力表。本实用新型能够检测管片的渗透性,对管片质量作出合理评估,有效解决了盾构施工中管片渗透性不易测量的难题,而且本实用新型结构简单,操作方便,易于在盾构施工中进行推广。
Disclosed is a duct piece infiltration detector for shields. A support is arranged below an arc plate which is provided with a water inlet hole. The water inlet hole is connected with a water pump, and a duct piece to be detected is disposed above the arc plate. A sealing frame is arranged between the arc plate and the duct piece to be detected and made of rubber. The water pump is provided with a pressure gauge. Infiltration of the duct piece can be detected by the duct piece infiltration detector, and quality thereof can be evaluated reasonably. The problem that infiltration of the duct piece during shield construction is not easy to be measured is effectively solved. In addition, the duct piece infiltration detector for shields is simple in structure, convenient to operate and easy to be popularized in shield construction.
