Construction method of upper formwork combined support of cast-in-place bridge crossing debris flow gully
The invention discloses a construction method of an upper formwork combined support of a cast-in-place bridge crossing a debris flow gully. The construction method comprises the following steps that S1, foundation treatment is conducted, specifically, a construction site is hardened; s2, strip-shaped foundation construction, wherein a plurality of strip-shaped foundations are poured on the foundation in the river channel at intervals, and steel plates are fixedly arranged on the strip-shaped foundations; s3, steel pipe pile stand column construction, wherein steel pipe stand columns are fixed to the steel plates; s4, I-shaped steel construction: arranging two pieces of I-shaped steel at intervals in the transverse bridge direction of the steel pipe stand column, and arranging an electric hydraulic jack beside the steel pipe stand column; s5, bailey beam construction is conducted, specifically, bailey beams are installed on the I-shaped steel; s6, support installation, wherein a socket and spigot type full framing is installed above the bailey beam, and an electric hydraulic jack is connected with a disc buckle frame; the disc buckle type full framing is erected on the bailey truss on the riverway to cross the gully at a time, normal passing of debris flow is facilitated, and damage and influence of gully flood discharge on bridge construction are avoided.
本发明公开了一种横跨泥石流冲沟现浇桥梁上部模板组合支架的施工工法，包括如下步骤：S1、地基处理：将施工场地作硬化处理；S2、条形基础施工：在河道内的地基上间隔浇筑多个条形基础，条形基础上固定设置钢板；S3、钢管桩立柱施工：将钢管立柱固定在钢板上；S4、工字钢施工：在钢管立柱横桥方向间隔设置两根工字钢，在钢管立柱旁设置电动液压千斤顶；S5、贝雷梁施工：将贝雷梁安装到工字钢上；S6、支架安装：在贝雷梁的上方安装承插式满堂支架，电动液压千斤顶与盘扣架连接；本申请通过在河道上采用贝雷架上搭设盘扣式满堂支架一次性跨越冲沟，有利于泥石流的正常通过，避免冲沟泄洪对桥梁施工的破坏和影响。
