Prefabricated culvert component and road and bridge culvert structure using same
The invention discloses a prefabricated culvert component and a road and bridge culvert structure using the prefabricated culvert component, and provides a culvert structure with excellent comprehensive performance. The prefabricated culvert component is a prefabricated component which is integrally prefabricated and formed by a steel bar grid and concrete and has a D-shaped section, the whole arc-shaped part is of an arc structure larger than or equal to 180 degrees, the wall thickness is uniform, secondary grouting areas are arranged at the two ends of the arc-shaped part, and lap joint steel bars extending from the steel bar grid are reserved in the secondary grouting areas. A drainage channel arranged in the depth direction of the culvert is arranged in the transition part, the bottom of the drainage channel is lower than the pavement height of the culvert after the asphalt pavement is laid, and at least one drainage hole is formed between the drainage channel and the interior of the culvert. The two ends of the culvert component are connected through secondary mortar, quick assembly construction can be achieved in the ready-made process, and water seepage can be effectively prevented.
本发明公开了一种预制涵洞构件及使用该构件的路桥涵洞构造，提供一种综合性能优秀的涵洞结构。预制涵洞构件是由钢筋网格和混凝土一体预制成型的断面为D字形的预制构件，且弧形部整体为大于等于180度的圆弧结构，且壁厚均一，弧形部的两端设置有二次灌浆区，且，该二次灌浆区内预留有自钢筋网格延伸的搭接钢筋，过渡部的内设置有沿着涵洞深度方向设置的排水通道，该排水通道的底部低于涵洞铺设沥青路面后的路面高度，且排水通道和涵洞内部之间设置至少一个排水孔。该涵洞构件在两端通过二次砂浆连接，在现成可以快速装配施工，且可以有效的防止渗水。
