Flood control type railway bridge reinforcing structure and construction method
The invention belongs to the technical field of railroad bed construction, and particularly relates to a flood prevention type railway bridge reinforcing structure which comprises a frame bridge main body, a lifting part and an anchoring assembly, the frame bridge main body is formed by connecting a plurality of frame bridge cylinders shaped like a Chinese character'hui ', the lifting part comprises a reinforcing assembly and railway ballasts, and the reinforcing assembly comprises a prefabricated part and a gravel gabion. The anchoring assembly comprises I-shaped steel and an H-shaped steel assembly, the I-shaped steel and the H-shaped steel assembly are fixed to the left side and the right side of the frame bridge main body, a steel wire net is fixed to the inner wall of the I-shaped steel, and an expanded head part is welded to the bottom of the H-shaped steel assembly and fixed in an underwater soil body; the H-shaped steel assembly is formed by welding and fixing two pieces of H-shaped steel together. According to the construction method, settlement deformation prevention of the railway bridge in the coal mining subsidence area can be achieved, water passing and flood prevention stability of the bridge under the flood impact and flooding conditions can also be achieved, the structure is reliable, and the construction method is high in operability.
本发明属于铁路路基施工技术领域，具体地涉及一种防洪式铁路桥加固结构，包括框架桥主体、抬高部和锚固组件，框架桥主体由多个回字形的框架桥筒连接而成，抬高部包括加固组件和道砟，加固组件包括预制构件和碎石格宾石笼，且预制构件的外侧填充有煤矸石，锚固组件包括工字钢和H型钢组件，工字钢和H型钢组件均固定在框架桥主体的左右两侧，工字钢的内壁上固定有钢丝网，H型钢组件的底部焊接有扩大头部分，且扩大头部分固定在水下土体中，H型钢组件由两根H型钢焊接固定在一起。本发明既能满足采煤沉陷区铁路桥的防沉降变形，也能满足在洪水冲击、漫水情况下桥梁的过水及防洪稳定，结构可靠，施工方法操作性强。
