Bridge grounding section structure for removing bump at bridge head

Abstract

The invention relates to a bridge grounding section structure for removing bump at a bridge head. The bridge grounding section structure is arranged between a bridge structure and the ground. The bridge grounding section structure comprises a plurality of pile foundations which are vertically arranged below a ground line at the ground and in contact with the subgrade, a bearing platform which is horizontally arranged above the pile foundations to connect the tops of all pile foundations, a plurality of webs which are vertically arranged on the top surfaces of the bearing platforms, and a top plate which is horizontally arranged above the webs to connect the top parts of all webs, wherein the bottom part of each web is connected to the bearing platform; the pile foundations, the bearing platform, the webs and the top plate are connected into a whole; the top plate is used for bearing vehicle load; the webs and the bearing platform are used for transmitting the vehicle load on the top plate to the pile foundations; the pile foundations transmit the vehicle load to the subgrade. With the adoption of the bridge grounding section structure, the phenomenon of bump caused by differential settlement between a bridge abutment and earth filling behind the abutment due to excessive earth filling thickness at the bridge head can be removed; in addition, the outer contour is the same as the bridge, so that the landscape effect is improved.

Description

technical field [0001] The invention relates to a bridge grounding section structure, in particular to a bridge grounding section structure capable of effectively eliminating vehicle jumping at a bridge head, and belongs to the technical field of bridge engineering. Background technique [0002] Judging from the operation status of the bridges put into use in my country at present, due to the large thickness of the fill soil behind the bridge abutment, under the action of self-weight and driving load, it will cause differential settlement between the abutment and the fill soil behind the abutment, so that the vehicle will The phenomenon of vehicle jumping occurs during driving, which greatly reduces the speed of vehicles and the capacity of roads, and also greatly reduces the comfort of driving, which ultimately affects the economic and social benefits of bridge construction. [0003] According to the existing technology, there are mainly the following measures for the govern...

AI Technical Summary

Problems solved by technology

[0009] The comprehensive application of one or more of the above methods can alleviate the phenomenon of vehicle jumping at the bridge head to a certain extent, but due to the stiffness difference between the bridge and the road, especially when the thickness of the backfill is large, the settlement difference still cannot be achieved. avoid

Therefore, the above method does not fundamentally solve the problem of jumping at the bridge head, but also generates some other problems, such as: boarding out, secondary jumping, etc.
