UHPC bridge suitable for rural highway and construction method of UHPC bridge
The invention discloses a UHPC bridge suitable for rural highways and a construction method thereof.The UHPC bridge comprises a main beam, a bridge deck slab and a pavement layer, and the main beam comprises two UHPC anti-collision guardrails located on the two sides of the bridge deck slab; prestressed steel beams, tensile steel bars, pre-buried sections of bridge deck transverse steel bars and a plurality of longitudinal structural bars are arranged in the UHPC anti-collision guardrail, the tensile steel bars are arranged on the collision face of the UHPC anti-collision guardrail, and the lower ends of the tensile steel bars are bound and fixed to the pre-buried sections of the bridge deck transverse steel bars. The tensile steel bars are further fixedly connected with the longitudinal constructional bars; the bridge deck slab transverse reinforcing steel bars are annular stirrups, and the bridge deck slab transverse reinforcing steel bars and the bridge deck slab longitudinal reinforcing steel bars in the bridge deck slab are welded and fixed. On the basis of meeting the flood control and navigation requirements of the river channel, the height of the bridge structure can be reduced, and the length of a bridgehead wiring road is reduced.
本发明公开了一种适用于农村公路的UHPC桥梁及其施工方法，所述UHPC桥梁包括主梁、桥面板和铺装层，所述主梁包括位于所述桥面板两侧的两道UHPC防撞护栏，所述UHPC防撞护栏的内部设置有预应力钢束、受拉钢筋、桥面板横向钢筋的预埋段和多根纵向构造筋，所述受拉钢筋设置在所述UHPC防撞护栏的迎撞面并且所述受拉钢筋的下端与所述桥面板横向钢筋的预埋段绑扎固定，所述受拉钢筋还与所述纵向构造筋固定连接；所述桥面板横向钢筋为环状箍筋，并且所述桥面板横向钢筋与所述桥面板内的桥面板纵向钢筋焊接固定。本发明在满足河道防洪及通航要求的基础上，可降低桥梁结构高度，减少桥头接线道路的长度。
