Watertight access door structure of steel box arch bridge
The invention relates to the field of bridge structures, in particular to a watertight access door structure of a steel box arch bridge, which can ensure the sealing performance while ensuring the convenience of opening and closing, and the structure comprises an access hole arranged at the bottom of a steel box girder, a manhole stiffening ring fixedly arranged along the access hole and a manhole cover plate in closed fit with the manhole stiffening ring, the manhole cover plate is rotationally connected with a cover plate connecting piece fixedly arranged on the steel box girder, the manhole cover plate is in closed fit with the manhole stiffening ring through a cover plate sealing mechanism arranged on the steel box girder, and a sealing ring structure matched with the edge of the manhole stiffening ring is arranged on the surface of the side, facing the manhole stiffening ring, of the manhole cover plate. The sealing ring structure is tightly attached to the edge of the manhole stiffening ring in a sealed mode. According to the invention, the sealing ring structure matched with the edge of the manhole stiffening ring is arranged on the surface of the side, facing the manhole stiffening ring, of the manhole cover plate, and therefore the sealing performance requirement is met. The watertight access door structure is particularly suitable for a steel box bridge structure of a bridge.
本发明涉及桥梁结构领域，尤其是一种在保证开闭便利性的同时，还可以保证密闭性的密封性的钢箱拱桥水密检修门结构，包括设置于钢箱梁底部的检修孔、沿检修孔固定设置的人孔加劲环以及与人孔加劲环密闭配合的人孔盖板，人孔盖板与固定设置于钢箱梁上的盖板连接件之间可转动连接，人孔盖板通过设置于钢箱梁上的盖板密封机构而与人孔加劲环密闭配合，人孔盖板朝向人孔加劲环一侧的表面上设置有与人孔加劲环边缘互相匹配的密封环结构，所述密封环结构与人孔加劲环边缘紧贴密封。本发明采用让人孔盖板朝向人孔加劲环一侧的表面上设置有与人孔加劲环边缘互相匹配的密封环结构，从而保证了密封的性能要求。本发明尤其适用于桥梁的钢箱桥结构之中。
