C60高性能补偿收缩混凝土预制T梁封端技术

Ending Sealing Technology of C60 High Performance Shrinkage Compensating Concrete Precast T-beam

补偿收缩混凝土封端技术能够可靠保证桥梁伸缩缝预留宽度的准确、顺直,在伸缩缝本身及安装质量没有问题的情况下,能够保障建成通车后桥梁伸缩缝的合理使用寿命,有效提高封端的施工质量,确保封端混凝土的密实度以及与梁体混凝土的粘结程度,降低返工返修的几率,从而改变原来使用干硬性补偿收缩混凝土需要几次填塞的问题,保证了箱梁的耐久性。

The compensation contraction concrete sealed end technology can guarantee reliably the bridge expansion joint reservation width accurate,is suitable straight,under the condition that the expansion joint itself and the installation quality are no problems,it can guarantee the reasonable service life of the bridge expansion joint after the completion and opening to traffic,improved the sealed end construction quality effectively,guarantees the sealed end concrete compactness as well as with the Liang body concrete caking degree,reduced the doing over repair probability;Thus changed the original use dry and hard compensation contraction concrete to need several times to pad,has guaranteed the box Liang’s durable request.
