UHPC precast arched girder combined type aqueduct
The invention discloses a UHPC precast arched girder combined type aqueduct. The UHPC precast arched girder combined type aqueduct comprises an arched structure and an aqueduct main body, wherein endribs of the aqueduct main body are hinged with the top end of the arched structure; the aqueduct main body comprises a plurality of sections of precast slot bodies; a wet jointing structure is arranged between every two adjacent precast slot bodies; the wet jointing structure comprises reinforcing steel bars and ultrahigh-performance concrete layers; the fixed ends of the reinforcing steel bars are fixedly connected to the precast slot bodies; exposed ends of the reinforcing steel bars are connected to the ultrahigh-performance concrete layers; and the bottoms of the ultrahigh-performance concrete layers are connected to the top end of the arched structure. The stress characteristics of the arched girder combined type aqueduct structure are sufficiently utilized, high-strength ultrahigh-performance concrete is adopted, applicable span is 150-500 m, applicable span of the conventional concrete girder arched combined type aqueduct is 50-120m which is 3-4 times that of a conventional arched girder type aqueduct.
本发明公开了一种UHPC预制拱梁组合式渡槽，包括拱上结构和渡槽主体，所述的渡槽主体的端肋与拱上结构的顶端铰接，所述的渡槽主体包括多段预制槽身，相邻的两个所述的预制槽身之间设有湿接结构，所述的湿接结构包括钢筋和超高性能混凝土层，所述的钢筋的固定端与所述的预制槽身固定连接，所述的钢筋外露端与所述的超高性能混凝土层连接，所述的超高性能混凝土层的底部与所述的拱上结构顶端连接。本发明充分利用拱梁组合式渡槽结构受力特点，采用高强度的超高性能混凝土，适用跨度为150～500m，传统混凝土梁拱组合式渡槽的适用跨度为50～120m，是传统拱梁组合式渡槽的3～4倍。
