Swivel bridge with waterproof spherical hinge system
The invention provides a swivel bridge with a waterproof spherical hinge system. The bridge comprises a lower bearing platform poured by concrete, a second impermeable concrete layer is poured on thelower bearing platform; a lower spherical hinge is arranged on the second impermeable concrete layer; an upper spherical hinge matched with the lower spherical hinge is arranged on the lower sphericalhinge; a first impermeable concrete layer is poured on the upper spherical hinge; additives are added into the first impermeable concrete layer and the second impermeable concrete layer in the concrete preparation process; the admixture is a cement-based capillary crystalline master batch and polypropylene fiber, the mass ratio of the cement-based capillary crystalline master batch to cement in the concrete is 1.5: 100-2.5: 100, and 0.8-1.2 kg of polypropylene fiber is added into per cubic meter of concrete. According to the swivel bridge provided by the invention, normal work of the swivel spherical hinge is ensured not to be invaded and disturbed by moisture through a mode of combining additive waterproofing and coating waterproofing.
本发明提供一种具有防水球铰体系的转体桥梁，包括混凝土浇筑的下承台，下承台上浇筑第二抗渗混凝土层，第二抗渗混凝土层上设置的下球铰，所述的下球铰上设置有与其配合的上球铰，上球铰上浇筑有第一抗渗混凝土层，所述的第一抗渗混凝土层和第二抗渗混凝土层在混凝土制备过程中添加外加剂，外加剂为水泥基渗透结晶母料和聚丙烯纤维，水泥基渗透结晶母料与混凝土中水泥的质量比为1.5：100‑2.5：100，聚丙烯纤维在每立方米混凝土中加入0.8‑1.2kg。本发明提供的转体桥梁通过外加剂防水和涂料防水相结合的方式保证转体球铰不受水分侵扰正常工作。
