Turnover underground diaphragm wall measure truss

The utility model discloses a turnover underground diaphragm wall measure truss which comprises a reinforcement cage mechanism, a measure truss mechanism is connected in the reinforcement cage mechanism in a sliding mode, the reinforcement cage mechanism and the measure truss mechanism are connected through a limiting fastener mechanism, and the limiting fastener mechanism comprises a U-shaped fastener. One end of the U-shaped fastener is in threaded connection with a limiting bolt, the outer portion of the limiting bolt is in sliding connection with a limiting embedded piece, and one end of the limiting bolt is in threaded connection with a limiting nut. The turnover underground diaphragm wall truss system is adopted to replace an original truss welded on a reinforcement cage, so that the purposes of saving time, saving manual and mechanical cost and saving reinforcement materials are achieved, the production efficiency is improved, the problems of short construction period, low construction cost and the lik
