Pollution discharge anti-blocking device of shield tunneling machine

A pollution discharge anti-blocking device of a shield tunneling machine comprises an anti-blocking structure, a clean water source, a booster pump, an electromagnetic valve, a pollution discharge pipe, a lower computer and an upper computer. The anti-blocking structure is provided with a sewage inlet and a high-pressure water connector, and the sewage inlet is connected with a sewage pipe; wherein the clean water source, the booster pump, the electromagnetic valve and a high-pressure water connector of the anti-blocking structure are connected in sequence, and the anti-blocking structure is connected to the blow-off pipe; the lower computer is connected with the booster pump, the electromagnetic valve and the upper computer. The utility model has the advantages of enhancing the flowability and deslagging capacity of sewage and possibly solving the problem that the sewage pump is damaged due to the fact that the sewage pipeline is easily blocked in the current construction process. 一种盾构机排污防堵装置，包括防堵结构、清水源、增压泵、
