Embodiment Construction
[0013] Such as figure 1 , 2 As shown, a road bridge vehicle upper collision protection system is composed of a bridge protection system and a pre-protection warning system. The bridge protection system includes a reaction force support column 12 fixedly installed on the outside of the bottom surface of the beam of the bridge 1. An energy-consuming liquid steel silo 10 filled with energy-consuming liquid is movably installed on the outer side of the reaction force support column 12, an energy-consuming support column 13 is installed inside the energy-consuming liquid steel silo 10, and rubber is fixed on the outside of the energy-consuming support column 13 The plate 9, the outer side of the reaction force support column 12 and the inner side of the energy dissipating support column 13 are respectively movably installed in the energy consuming liquid steel bin 10, and the installation positions of the reaction force support column 12 and the energy dissipating support column 13 ar...

The invention relates to a system and method for protecting the upper portion of a highway bridge against vehicle collision. The system is composed of a bridge protection system and a pre-protection warning system. The bridge protection system comprises counterforce supporting columns fixedly installed on the outer side of the beam bottom face of a bridge. An energy dissipation liquid steel bin filled with energy dissipation liquid is movably installed on the outer sides of the counterforce supporting columns. Energy dissipation supporting columns are installed in the energy dissipation liquid steel bin. A rubber plate is fixedly installed on the outer sides of the energy dissipation supporting columns. The outer sides of the counterforce supporting columns and the inner sides of the energy dissipation supporting columns are movably installed in the energy dissipation liquid steel bin. The installation positions of the counterforce supporting columns and the energy dissipation supporting columns are distributed in a staggered mode. The system and method for protecting the upper portion of the highway bridge against vehicle collision have great bridge protection and anti-collision functions, the upper portion of the highway bridge can be protected against vehicle impact, and accidents are avoided.
Description
Technical field [0001] The invention relates to the field of highway bridge protection, in particular to an upper collision protection system of a highway bridge vehicle and a protection method thereof. Background technique [0002] At present, super-high vehicles often crash the facilities at the bottom of the bridge. With the acceleration of urbanization, three-dimensional transportation has become an important way to solve the urban traffic pressure. However, incidents of super-high vehicles hitting the bridge superstructure are also increasing day by day. Traditional protective measures have no obvious advantages, and the installation and use are very troublesome, and the work and operation efficiency are low. At present, there are many research foundations and patented products on the protection of vehicles hitting bridge piers and ships hitting bridges at home and abroad. However, the current patented products have great defects in the specific design and construction. A...
