8，钢筋笼下落：严格细致地下好钢筋笼，并将其牢固地绑扎或焊接在孔口，下导管时，使导管顺桩孔中心位置而下，斜桩灌注时，导管的每个接头处加装外表面光滑的罩子，避免挂住钢筋笼，在浇灌中，一经发现钢筋笼下落立即停止浇灌混凝土，将笼吊至设计标高重新固定，如笼沉入混凝土中拔不出来，选先探明笼顶标高，沉入深度，在断桩部位一节钢筋笼，然后继续浇筑混凝土。

When working with mud pumps, high divssure water must be injected into the packing chamber to protect the shaft seal assembly. The main pump shall not close the high divssure cleaning pump when it is working normally. The suction process in the pump performance table refers to the anti-citation characteristics of the pump under the condition of clean water at room temperature. In the pumping of sediment operation should be as far as possible to make the pump inlet divssure as positive divssure. The gap between the impeller and the front and rear liners should be adjusted when the impeller and the lining plate are replaced, and the axial clearance of the impeller and the lining plate has a great influence on the performance and service life of the pump.
