以东深供水改造工程塘厦金湖至窑杭段高架渡槽为研究对象,通过大型仿真模型试验进行可行性论证,提出了一种以U形GB复合橡胶止水带为主体的全新渡槽伸缩缝止水结构.认为该止水在40mm张开变位、40mm沉降变位、60mm剪切变位和20m水头的同时作用下,该止水结构具有稳定可靠的止水效果;该止水破损后易于修复,且因采用了GB嵌缝材料,止水效果易得到保证.
Taking Donghuashen water supply alteration project from Jinhu to Yaohang section of Tangxia elevated aqueduct as the research object, the feasibility demonstration was carried out by large-scale simulation model test. A new aqueduct expansion joint with U-shaped GB composite rubber water-stop as main body It is considered that the water stop structure has a stable and reliable water stop effect under the action of 40mm open displacement, 40mm settlement displacement, 60mm shear displacement and 20m water head. After the water stop is damaged Easy to repair, and because of the use of GB caulking material, water stop effect is easily guaranteed.
