摘　　要：孔内电视在中远船坞升浆砼底板检测中的应用，能直观清晰地看到对该钻孔部位升浆砼的密实性，与升浆过程纪录曲线对比分析，可以基本得出升浆砼实体质量的情况。在补充压浆及抽水期间利用４５００ＡＬ型沉降仪与６３５０Borehole television was used in the inspection of the bed plate made of prepacked aggregate concrete in Zhongyuan Dock. Using the instrument, the density of prepacked aggregate concrete can be visually and clearly observed from the borehole where the borehole television is placed. When comparing with the recorded curves during the placing of mortar, the quality of the prepacked aggregate concrete mass can be basically obtained. During the supplementary placing of mortar and water pumping, settlement gauges 4500AL and inclinometers 6350 were used to monitor the displacement and lifting of the bed plate so as to control the pressure of mortaring and the speed of water pumping, which proved to be a reliable method for ensuring the quality and safety of the works.
