Method for solving problem of vehicle bump at bridge head and structure thereof

Abstract

The invention relates to a novel method for solving the problem of vehicle bump at bridge head, which is concretely implemented as follows: setting a transition zone between a rigid bridge abutment and a soft subgrade, arranging an adjustable box structure in the transition zone, and adjusting the gradient (line shape) of a cover plate above the box structure in the transition zone by an adjustable support when the subgrade sedimentates unevenly, thus rapidly and conveniently smoothing the road surface at the connecting part of the transition zone and the subgrade so as to eliminate the hidden danger of the vehicle bump at bridge head caused by uneven sedimentation of the rigid bridge abutment and the soft subgrade.

Description

A method and its structure for solving the problem of vehicle jumping at the bridge head technical field The invention relates to a construction technology for solving the problem of vehicle jumping at the bridge head. Background technique During the use of high-grade highways, the phenomenon of vehicle jumping at the bridge head has always been one of the problems that plague the majority of engineers and technicians. Especially in recent years, with the increasing scale of high-grade highway construction in my country, the role of highway traffic in the development of the national economy has become more and more important. How to effectively control bridge head jumping to ensure highway traffic safety and high-speed operation has become increasingly important. attracted widespread attention. As far as the current situation is concerned, treatment measures such as compaction control, setting of bridge head slabs, and application of geogrids have been proposed, some of wh...
