Structure Design and Type Selection Analysis of Highway Bridge Deck Runoff Collection System
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.
