Transition section structure for underground tunnel access place and viaduct bridge connection and construction method
The invention relates to a transition section structure for underground tunnel access place and viaduct bridge connection and a construction method. The transition section structure comprises a transition section structure body extending longitudinally along a line, wherein the transition section structure body comprises a bottom plate and side walls located at two sides of the bottom plate; a lane plate used for supporting ballast bed structures is arranged in the transition section structure body and located above the bottom plate; the lane plate is arranged in a slope mode in the longitudinal direction of the line; and a lane plate structure is arranged in the transition section structure body to solve the height difference problem that the rail surface is higher than the ground, and the height of boundary rail surfaces between tunnels and roadbeds and between tunnels and bridges is enlarged and higher than the designed water level. Open-cut U-shaped grooves are directly adopted tobe provided with the lane plate structure to be connected with viaduct bridges, short roadbeds are omitted, composite foundations, bearing piles and other measures are arranged on the bottom plate ofU-shaped groove structures according to different geological conditions, the structural rigidity is improved, the problem of differential settlement caused by different structural rigidities is solved, and land acquisition of roadbed sections is reduced.
本发明涉及一种地下隧道出入地与高架桥连接的过渡段结构及施工方法，过渡段结构包括沿线路纵向延伸的过渡段结构体，所述过渡段结构体包括底板以及位于底板两侧的侧墙，所述过渡段结构体内位于底板上方设有用于支撑道床结构的车道板。所述车道板沿线路纵向呈斜坡设置。在过渡段结构体内设车道板结构解决轨面高出地面的高差问题，提高隧道与路基、隧道与桥梁分界轨面高度，高于设计水位。本发明直接采用明挖U型槽设车道板结构接高架桥梁，取消短路基并根据不同地质情况，U型槽结构底板设复合地基、承载桩等措施，提高结构刚度，以解决不同结构刚度不同引起差异沉降问题，减少路基段征地。
