Abstract
A simple support arch bridge straining beam construction support system comprises a bailey beam, a steel tube support, concrete strip bases, a filling pole and a bowl button support. The support strides an existing highway and penetrates through a culvert of the highway. Six ways of the concrete strip bases are arranged on the road face of a road. The top of each strip base is provided with a bailey beam bearing support system supported through the steel tube upright pole so that four double-direction driveway passage door caves are formed. A hole-drilling filling pole base, a pole top concrete straining beam, the steel tube upright pole, the bailey beam bearing support and the bowl button support combination support system are adopted by an area outside an existing road base slope. A steel tube upright pole anti-top system is arranged in the culvert plate bottom to ensure safety of an existing culvert under a bearing support. The simple support arch bridge straining beam construction support system can be applied to striding of a high filling square base and the existing road and the culvert of large slope, and can ensure safety of the existing road traffic passage and safety of the existing culvert structure, and stability of the support system and the like.
