Equipment type bridge end transition slab structure and construction method
The invention discloses an equipment type bridgehead transition slab structure and a construction method, and belongs to the technical field of road engineering, the equipment type bridgehead transition slab structure comprises a bridge pier, a bearing platform is arranged above the bridge pier, a back wall is arranged above the bearing platform, damping supports are arranged on the two sides of the back wall, a bridgehead transition slab is arranged above the damping support on the left side of the back wall, and a limiting plate is arranged on the left side of the bridgehead transition slab; and a bridge/plate is arranged above the damping support on the right side of the back wall. According to the equipment type bridgehead transition slab structure and the construction method, the double rows of compaction piles are arranged below the bridgehead transition slab end far away from the bridge pier end and at the position close to the bridgehead transition slab, foundation reinforcement is conducted on the abutment back to form a composite foundation, the bearing capacity of the abutment back is improved, the settlement difference of a roadbed is reduced, and the construction efficiency is improved. Non-uniform deformation of the end, far away from the bridge pier, of the bridge-end transition slab and the abutment back is coordinated; the bridgehead lap joint plate is designed to be in an inverted L shape and is in lap joint with the limiting plate on the bearing platform, and the problems that the bridgehead lap joint plate falls off and the bridgehead lap joint plate and the back wall deform and are not coordinated can be solved.
本发明公开了一种装备式桥头搭板结构及施工方法，属于道路工程技术领域，包括桥墩，所述桥墩上方设有承台，所述承台上方设有背墙，所述背墙两侧均设有减震支座，所述背墙左侧的所述减震支座的上方设有桥头搭板，其左侧设有限位板，所述背墙右侧的所述减震支座的上方设有桥梁/板。本发明采用上述的一种装备式桥头搭板结构及施工方法，在远桥墩端的桥头搭板端下方和近桥头搭板处分别设置双排挤密桩，对台背进行地基加固形成复合地基，提高台背的承载能力，减少路基的沉降差，协调桥头搭板远桥墩端与台背的不均匀变形；将桥头搭接板设计成倒L形，在承台上与限位板搭接，可以防止桥头搭接板脱落及桥头搭接板与背墙变形不协调问题。
