Gravity type bridge abutment anti-sedimentation cracking reinforcing device and reinforcing method

The invention discloses a gravity type bridge abutment anti-sedimentation cracking reinforcing device and a machining method, and belongs to the technical field of building bridges, the device comprises a bridge abutment body and a bridge deck erected on the bridge abutment body, the bridge abutment body comprises a bottom platform and a plurality of branch platforms sequentially spliced on the bottom platform in the vertical direction, and a guide rod seat is arranged on the vertical deck; the rack is connected with a guide rod through a connecting rod, the guide rod penetrates through a guide rod base in a sliding mode in the vertical direction and then is connected to a support, and the support is fixed to the bottom table. After the bottom platform settles, the bottom platform can drive the rack to move downwards in the vertical direction through the guide rod, the rack drives the gear to rotate after moving, and therefore the inclined panel is driven to rotate towards the side away from the bridge abutme
