Construction method of aqueducts above bridge
The invention discloses a construction method of aqueducts above a bridge. The construction method comprises the steps of support arrangement, technological process, construction method, support prepressing, aqueduct supporting frame dismantling, support construction safety protection, formwork engineering construction method, steel bar engineering, concrete construction, formwork dismantling and road and bridge support constructing. The road and bridge supports comprise two layers of H-shaped steel, chain blocks and a support body, wherein the H-shaped steel is arranged on the two sides of a stand column, the H-shaped steel on the lower layer is tensioned and fixed to the stand column through the chain blocks, the H-shaped steel on the upper layer is vertically installed on the H-shaped steel on the lower layer, and then the support body is erected on the H-shaped steel on the upper layer. The support arrangement is composed of two steps of super-large load formwork technical parameters design and supporting system design. According to the technological process, aqueduct columns, longitudinal and transverse beams and aqueduct bodies are constructed separately; the construction method comprises the steps of foundation treatment of the supporting system, support erection and support inspection and acceptance; the formwork construction method comprises the steps that longitudinal and transverse formworks are installed; and the reinforcing steel bar engineering comprises two steps of reinforcing steel bar storage and reinforcing steel bar installation.
桥梁上方渡槽施工方法，包括支架布置、工艺流程、施工方法、支架预压、渡槽支撑架拆除、支架施工安全防范、模板工程施工方法，钢筋工程、混凝土施工、模板拆除和路桥支架；所述路桥支架包括工字钢、手拉葫芦和支架，所述工字钢设置在立柱的两侧，工字钢设置有两层，通过手拉葫芦将下层的工字钢拉紧固定在立柱上，上层工字钢垂直安装在下层工字钢上，再将支架搭在上层的工字钢上；所述支架布置由超大荷载模板技术参数和支撑系统设计两个步骤组成；所述工艺流程将渡槽柱子、纵横梁、槽体分开施工；所述施工方法步骤：支撑系统的基础处理、支架搭设，支架检查验收；所述模板施工方法为纵横模板安装；所述钢筋工程包括钢筋储存和钢筋安装两个步骤。
