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 abutment body, and pretension force is applied to the bridge abutment body through the anchor rod. The concrete ring beam is poured on the abutment to reinforce the abutment, auxiliary pits are excavated in the ground, then the holes are drilled to install the prestress opposite-pull anchor cables, meanwhile, grouting is conducted at the bottom of the abutment, the abutment is reinforced to prevent the abutment from cracking, and meanwhile settlement of the abutment is reduced.
本发明公开了一种重力式桥台防沉降开裂加固装置及加工方法，属于建筑桥梁技术领域，装置包括桥台本体、架设在桥台本体上的桥面板，桥台本体包括底台、沿着竖向依次拼接在底台上的若干分台，竖直面板上设置有导杆座，齿条通过连接杆连接有导杆，导杆沿竖向滑动穿过导杆座后连接至支座，支座固定在底台上；底台在沉降后，底台能够通过导杆带动齿条沿竖向向下移动，齿条移动后带动齿轮转动，从而驱动斜面板朝向背离桥台本体一侧旋转，通过锚杆对桥台本体施加预拉力。本发明通过在桥台浇筑混凝土圈梁加固桥台外，还在地面开挖辅助坑洞，而后钻孔安装预应力对拉锚索同时在桥台底部注浆，对桥台进行加固以预防桥台开裂同时减少桥台沉降。
