Construction method of steel-concrete combined truss girder in cantilever state
The invention discloses a construction method for a steel-concrete combined truss girder in an overhanging state, and belongs to the technical field of bridge construction. The method comprises the steps that S1, bailey beams are erected; s2, laying and pre-pressing a bottom die; s3, laying steel rails of the gantry crane; s4, mounting the gantry crane; s5, web member positioning component supports are installed; s6, fixed pay-off of the web member; s7, paired triangular units are assembled; s8, hoisting the triangular units; s9, performing linear adjustment; s10, screwing a bolt; s11, lower chord concrete pouring; and S12, the positioning support and the gantry crane are dismantled. The bridge deck gantry crane is used for erecting, material feeding and assembling are conducted at the end, the lower road is avoided and is not affected, and smooth traffic is guaranteed.
本发明公开了一种钢‑混组合桁梁悬挑状态下的施工方法，属于桥梁施工技术领域；其包括：S1，贝雷梁搭设；S2，底模铺设及预压；S3，龙门吊钢轨铺设；S4，龙门吊安装；S5，腹杆定位构件支撑安装；S6，腹杆构件定放线；S7，拼装成对三角形单元；S8，吊装三角形单元；S9，线形调整；S10，螺栓施拧；S11，下弦混凝土浇筑；S12，定位支撑及龙门吊拆除。本发明利用桥面龙门吊架设，上材料和拼装均在端部进行，避开了下方的道路，下方道路不受影响，保证了交通畅通。
