桥墩段也是两侧非溢坝的一个坝段,采用重力式混凝土结构。由于坝轴线的防渗帷幕从其下通过,因此,两墩间铺设底板。底板与两墩之间的接缝布置止水,构成不透水的U形槽。左墩由于块体较小,如单独进行稳定计算,右上角出现拉应力。因此需与左侧非溢流坝的相邻两坝段用接缝灌浆连成整块,使地基应力得以调整。
Bridge pier section is also a non-spill dam on both sides, the use of gravity concrete structure. As the dam axis anti-seepage curtain from under it, laying between the two piers floor. The seams between the base plate and the two piers are arranged to stop water and form a U-shaped groove impermeable to water. Left pier due to the smaller block, as a separate stable calculation, tensile stress appears in the upper right corner. Therefore, it is necessary to join the adjacent two dam sections of the non-spill dam on the left with grout joints to make the foundation stress be adjusted.
