Abstract

The present invention relates to a wedge-shaped flexible butt plate for road bridge abutment. On the bridge abutment at least one layer of double-layer earth grid chamber is set, and under the double-layer earth grid chamber a top layer of single-layer earth grid chamber is set or is not set, and on the pile cap or base layer ground a base layer of single-layer earth grid chamber is set, and between the top layer of single-layer earth grid chamber or double-layer earth grid chamber and base layer of single-layer earth grid chamber at least two layers of intermediate layer of single-layer earth grid chamber are set. Said invention utilizes the stereo structure of earth gird chamber reinforced layer to form flexible structure layer with good integral property and large rigidity.

Description

technical field [0001] The invention belongs to the technical field of construction of bridges and viaducts and assembly of bridges, and in particular relates to piers of bridge components and wedge-shaped flexible boards of highway bridge abutments of bridge abutments. Background technique [0002] Vehicle jumping at the bridge head refers to the deformation, breakage, or even potholes of the road surface or the board in the connection area between the road and the back of the bridge platform, so that the vehicle driving through this area will obviously jump and bump after being impacted. The vehicle jumping at the bridge head is a common phenomenon on the road. One of the diseases is also a major technical problem that has plagued the road industry for many years. It not only seriously affects the comfort of driving, reduces the speed of vehicles and the capacity of roads, affects the use of bridges and vehicle life, but also greatly increases road traffic. The cost of rep...
