Low-clearance spanning bridge construction method
The invention provides a low-clearance spanning bridge construction method which comprises the following steps: S1, foundation construction: a foundation adopts a C25 reinforced concrete strip-shaped structure; s2, a buttress steel pipe and a bailey beam support are erected; s3, bottom die I-shaped steel and square timber are laid; s4, mounting a bottom die; s5, pre-pressing construction is carried out; s6, a low mold is adjusted, and an outer side mold is installed; s7, steel bars and prestressed pipelines are bound; s8, mounting and adjusting an outer side mold and an inner mold plate; s9, pouring concrete; s10, concrete curing is conducted; s11, prestress tensioning is conducted; s12, grouting the pipeline; and S13, the support is dismantled. According to the low-clearance-span bridge construction method, under the low-clearance-span condition, the bridge can be constructed safely, rapidly and economically, passing of a road below is not affected, the safety of an operation line is guaranteed, the efficiency and quality of bridge construction can be improved, and the cost and risk of bridge construction are reduced.
本申请提供了一种低净空跨越的桥梁施工方法，包括以下步骤：S1、基础施工，基础采用C25钢筋混凝土条形结构；S2、搭设支墩钢管和贝雷梁支架；S3、铺设底模工字钢及方木；S4、安装底模；S5、预压施工；S6、调整低模、安装外侧模；S7、绑扎钢筋及预应力管道；S8、外侧模及内模板安装调整；S9、灌注混凝土；S10、混凝土养护；S11、预应力张拉；S12、管道灌浆；S13、拆除支架。本申请提供的低净空跨越的桥梁施工方法，具有可在低净空跨越的条件下，安全、快速、经济地施工桥梁，不影响下方公路的通行，保证运营线的安全，并且可提高桥梁施工的效率和质量，降低桥梁施工的成本和风险。
