Construction method of steel trestle
A construction method of a steel trestle belongs to the technical field of temporary bridge construction and comprises the steps of bridge abutment foundation construction, bridge abutment body construction, bridge abutment cap construction, abutment back backfilling, bailey beam installation, bridge deck slab installation, guardrail installation and the like. According to the construction method, unique process parameters are designed in each stage of construction, the construction quality of each stage is guaranteed, particularly, the stability of an enlarged foundation and a subsequently-poured abutment body can be well guaranteed through the design of the concrete ridges, displacement and deflection cannot occur even if the concrete ridges are subjected to large external force side impact after construction and subsequent traffic use, the service life can be greatly prolonged, and the construction cost is reduced. The bearing capacity is improved; the embedded part is designed to be in a shape of Pi, so that the connection stability of the abutment body and the abutment cap can be well ensured; bailey beams and longitudinal I-shaped steel beams are designed, so that the overall stability and safety of the temporary bridge can be effectively improved; double I-shaped steel is welded on two sides of the bridge deck lane, so that the wheels can be effectively prevented from sliding off the bridge deck, and the deformation resistance of the bridge deck can be further improved.
一种钢栈桥的施工方法，所属临时桥梁建设技术领域，施工方法包括桥台基础施工、桥台台身施工、桥台台帽施工、台背回填、贝雷梁安装、桥面板安装和护栏安装等。本发明各阶段施工设计独特的工艺参数，保证各阶段的施工质量，尤其是混凝土楞设计能够很好的保证扩大基和后续浇筑的台身的稳定性，在施工及后续通车使用后，收到较大外力侧冲击也不会发生位移、偏斜，能够大幅提高使用寿命，以及提高承载力；设计预埋件为“兀”型，能够很好的保证台身与台帽的连接稳固性；设计贝雷梁附加纵向工字钢横梁能够有效增加便桥整体稳定安全性；设计桥面车道两侧焊接双工字钢，能够有效防止车轮滑下桥面，也会进一步辅助提高桥面的抗变形能力。
