摘　　要：为进一步完善和规范公路桥面径流收集系统,延长其服役寿命,先针对桥面径流收集系统的构造形式,对比分析了现有纵向排水管道固定构件的适应性,提出了不同桥梁截面形式所对应的最合理的排水管道悬挂附着方式;后针对桥梁伸缩缝位置、主桥与引桥截面变化处等的排水管道构造及设计问题,深入分析并提出了这些特殊位置处排水管道的连接方式。结果表明,针对不同桥梁截面形式,排水管道应采用不同悬挂附着方式,在桥梁结构特殊处应采用伸缩节或软管连接的方式。In order to further improve and standardize the highway bridge deck runoff collection system and extend its service life,this paper firstly focuses on the construction form of bridge deck runoff collection system,compares and analyses the adaptability of the existing longitudinal drainage pipe fixing components,and puts forward the most reasonable drainage pipe hanging attachment method corresponding to different bridge cross-section forms.After that,it focuses on the location of expansion joints of bridges,the cross-section change of main bridges and approach bridges,etc.,and puts forward in-depth analyses of the connection method of the drainage pipe in these special locations.The results show that for different bridge cross-section,the drainage pipe structure and design problems are analyzed.The results show that for different bridge cross-section forms,the drainage pipe should adopt different suspension attachment methods,and in the special place of bridge structure,expansion joints or hose connections should be adopted.
