Steel trestle abutment
The invention discloses a steel trestle abutment which comprises abutment steel pipe piles, abutment supports, abutment distribution beams, abutment steel panels and abutment guardrails, the number of the abutment steel pipe piles is two, and the abutment supports are fixedly connected to the upper portions of the two abutment steel pipe piles respectively; the two abutment supports are fixedly connected with the abutment distribution beam; the bridge abutment distribution beam is fixedly connected with a bridge abutment steel panel; a bridge abutment guardrail is arranged on the bridge abutment steel panel; soil retaining plates are arranged on the peripheral surfaces of the sides, close to the water bank, of the two abutment steel pipe piles; a self-balancing pressing plate is fixedly connected to the lower portion of the soil retaining plate, and two brackets are fixedly connected to the lower portion of the self-balancing pressing plate. The side, away from the water bank, of the abutment steel panel is connected and fixed to the trestle body. The self-balancing device has the advantages of being reasonable in structure, high in stability and capable of balancing lateral soil pressure borne by the bridge abutment steel pipe pile through soil pressure borne by the self-balancing pressing plate and vehicle loads, achieving self-balancing of the bridge abutment and avoiding the common problem that a conventional steel pipe pile bridge abutment laterally moves.
本发明公开一种钢栈桥桥台，包括桥台钢管桩、桥台支座、桥台分配梁、桥台钢面板和桥台护栏，其中：桥台钢管桩设置有两个，两个桥台钢管桩的上方分别固定连接有桥台支座；两个桥台支座均与桥台分配梁固定连接；桥台分配梁上固定连接有桥台钢面板；桥台钢面板上设置有桥台护栏；两个桥台钢管桩在靠近水岸一侧的周面上设置有挡土板；挡土板的下方固定连接有自平衡压板，自平衡压板的下方固定连接有两个牛腿；桥台钢面板远离水岸的一侧与栈桥主体衔接连接固定。有益效果：结构合理，稳定性高，能利用自平衡压板所受的土壤压力及车辆荷载来平衡桥台钢管桩所受的侧向土压力，实现桥台的自平衡，避免常规钢管桩桥台侧移通病。
