Soft soil foundation bridgehead bumping eliminating device
The invention discloses a device for eliminating bumping at a bridgehead of a soft soil foundation. The device comprises a bridge abutment, a soil retaining platform, a tower plate and a stress bracket, the tower plate is arranged between the bridge abutment and the top of the soil retaining platform; the stress support comprises a cross table, a first supporting component and a second supporting component. The cross-shaped table is fixedly connected with the butt strap, one end of the first supporting component and one end of the second supporting component are rotationally connected with the two sides of the cross-shaped table respectively, the other end of the first supporting component and the other end of the second supporting component are rotationally connected with sliding seats, the stress support is in sliding connection with the sliding grooves through the sliding seats, and elastic pieces are further arranged in the sliding grooves. The elastic piece abuts against the end of the sliding base. By the adoption of the design, the stress support is arranged between the approach slab and the soil retaining platform, impact force acting on the approach slab is counteracted through the stress support, the phenomenon that the baffle settles and forms slab staggering with an embankment is avoided, meanwhile, the spherical support is arranged between the bridge abutment and the approach slab, impact force acting on the connecting position of the approach slab and the bridge abutment is reduced, slab staggering is avoided, and the safety of the embankment is improved. The driving safety is influenced.
本发明公开了一种软土地基桥头跳车消除装置，包括：桥台、挡土台、塔板、应力支架；塔板设于桥台和挡土台的顶部之间；应力支架包括十字台、第一支撑构件、第二支撑构件；十字台与所述搭板固定连接，第一支撑构件和第二支撑构件的一端分别与十字台的两侧转动连接，第一支撑构件和第二支撑构件的另一端转动连接有滑座，应力支架通过滑座与滑槽滑动连接，滑槽内还设有弹性件，弹性件与滑座的端部抵接。采用以上设计，通过在搭板与挡土台之间设置应力支架，使作用于搭板上的冲击力经应力支架抵消，避免挡板沉降与路堤形成错台的现象，同时在桥台与搭板之间设置球面支座，降低作用于搭板与桥台连接处的冲击力，避免形成错台，影响行车安全。
