Splicing construction method of segmental prefabricated spliced bridge
The invention discloses a splicing construction method of a segmental prefabricated spliced bridge, which comprises the following steps of: S1, manufacturing a prefabricated segment consisting of a pier top segment and a non-pier top segment, respectively pre-burying a steel strand, and further forming a reserved hole channel in the non-pier top segment; s2, erecting a pier top section; s3, corresponding non-pier-top sections are lifted, and epoxy resin glue is smeared on the corresponding glue splicing faces; s4, a steel strand pre-buried in the previous erected prefabricated section penetrates through a reserved hole channel of the non-pier-top section to be erected; s5, glue splicing surface fitting is completed; s6, before the epoxy resin glue on the glue splicing surface is solidified, the steel strands penetrating through the reserved hole channels are tensioned; s7, the beam erecting machine is loosened; s8, the permanent prestress is tensioned; s9, high-strength mortar is poured into the corresponding reserved hole channels; and S10, the steps S3-S9 are repeated till assembly of all the prefabricated sections is completed. The construction process is simple and efficient, the adaptability is wide, the quality of the section beam glue splicing face is controllable, the construction period is shortened, and the construction efficiency is improved.
本发明公开的一种节段预制拼装桥梁的拼接施工方法，包括如下步骤：S1、制造由墩顶节段和非墩顶节段构成的预制节段，并分别预埋钢绞线，非墩顶节段还设置预留孔道；S2、架设墩顶节段；S3、起吊相应的非墩顶节段，并在对应胶拼面涂抹环氧树脂胶；S4、将上一节已架设的预制节段内预埋的钢绞线穿过即将架设的非墩顶节段的预留孔道；S5、完成胶拼面贴合；S6、在胶拼面环氧树脂胶凝固前，张拉已穿过预留孔道的钢绞线；S7、使架梁机械松勾；S8、张拉永久预应力；S9、向对应预留孔道内灌注高强砂浆；S10、重复步骤S3‑S9，直至完成所有预制节段的拼装。本发明施工工序简单高效，适应性广，节段梁胶拼面质量可控，有利于缩短施工周期，提高施工效率。
