Description
Technical field
The present invention relates to technical field of bridge engineering, in particular to the bridge steel anti-collision wall on a kind of highway across high-speed railway
Structure.
Background technology
Across high-speed railway bridge on traditional, railway under bridge is dropped down onto to prevent vehicle, goods and debris from turning over, jeopardizes high ferro row
Car safety, bridge floor anti-collision wall uses twice concrete anti-collision wall more, while anti-throwing net is set on the anti-collision wall of outside.Coagulation
Soil has the advantages that low cost, anticollision ability are strong.Concrete anti-collision wall is used in small span bridge or rigid bridge structure,
For in flexible structure or long-span bridge girder construction, the increase of bridge floor weight frequently can lead to construction investment increase and restrict across
The growth of degree.Now, a series of adverse effects of concrete anti-collision wall will amplify, and be frequently not optimal selection.
It has been proposed that using hollow-core construction as anti-collision wall, anti-collision wall can be greatly lowered in the anti-collision wall of hollow-core construction
Weight, as the Chinese invention patent of entitled " a kind of buffer-type roadbed anti-collision wall " of Patent No. " CN202730690U " proposes
A kind of hollow anticollision wall construction, the anti-collision wall include two parts, the solid section to play a supportive role and positioned at carrying out on part
Hollow parts, hollow parts are hollow steel bar concrete structure, inside be filled with sandstone, although such structure can reduce it is anti-
The overall weight of wall is hit, but its crashworthiness is poor, is easily damaged, and is not suitable for significantly promoting the use of.
The content of the invention
Present invention aim to the hollow anti-collision wall intensity for the prior art for solving to mention in above-mentioned background technology compared with
Difference, be not suitable for the problem of high-volume is promoted the use of, there is provided across the bridge steel anticollision wall construction of high-speed railway on a kind of highway.

It is separately fixed on the first column steel plate and starting stave.
Further described supporting construction also includes the second column steel being arranged between adjacent two piece of first stiffener
Plate；The second described column steel plate vertically arrange by direction, and the transverse ends of the second column steel plate are separately fixed at the first column
On steel plate and starting stave, the square steel tube being longitudinally arranged along level is equipped with the second column steel plate；Described square steel tube is along water
It is flat that multigroup supporting construction is connected to be overall longitudinally through the second column steel plate in multigroup supporting construction.
Sleeve pipe is equipped with further the second described column steel plate；Described sleeve pipe is the set being longitudinally arranged along level
Sleeve on square steel tube, sleeve pipe are connected with the second column Interal fixation.
It is vertically spaced apart that further described the first column steel plate side of starting stave direction is provided with polylith
Second stiffener；Second described stiffener one end is fixed on the sidepiece of starting stave, and the other end is vertical along horizontal cross to first
Post steel plate side extends, and the second stiffener is connected with the second column Interal fixation.
Further described starting stave lower end sets the raised kink in oriented bridge center line side；Described bending
Subordinate end, which is fixed on bottom plate, forms lower small wall body structure upper greatly with bottom plate, the second riser and top plate.
Further described starting stave sets the circular arc of oriented bridge center line side extension convex with top plate junction
Platform.
Further also include the second longitudinally arranged wall；Described the first wall and the second wall is placed in bridge
