Problems solved by technology

Rigid guardrail is a basically non-deformable guardrail structure, which can effectively prevent the high-speed movement of the vehicle, but it is difficult to guarantee the safety of the occupants
Semi-rigid guardrail is a continuous beam-type guardrail structure, which has certain rigidity and flexibility, and absorbs vehicle collision energy through its own deformation, but its protection ability is limited
The initial cost of the flexible guardrail is low, and it can prevent accumulation. It has better advantages when used in wind, snow and sandstorm areas, but its protection ability is weak

Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] Such as figure 1 and figure 2 As shown, the elevated railway roadside protective device of this embodiment includes a wave beam 2 and a reinforced concrete wall 1 embedded in the subgrade 100, and the reinforced concrete wall 1 is embedded with a plurality of roots extending upward from the top surface of the reinforced concrete wall 1. Columns 3 are arranged at intervals in sequence, and each column 3 is connected to the wave beam 2 through an energy-absorbing box 4 . The roadside protective device of the elevated railway can effectively prevent secondary accidents caused by the derailed train overturning or going off the line. Axially crushed, the column 3 can be bent and deformed, and the wave beam 2, the energy-absorbing box 4 and the column 3 form a multi-stage deformation energy-absorbing structure, which has a good bu...

Abstract

The invention discloses an elevated railway roadside protection device which comprises a corrugated beam and a reinforced concrete wall installed in a roadbed in an embedded mode, a plurality of standcolumns which extend upwards from the top face of the reinforced concrete wall and are sequentially arranged at intervals are embedded in the reinforced concrete wall, and all the stand columns are connected with the corrugated beam through energy absorption boxes. The elevated railway roadside protection device is good in buffering and energy absorption effect, high in protection performance andcapable of effectively preventing secondary accidents caused by overturning or derailing of a derailed train and greatly reducing the damage degree of the train.

Description

technical field [0001] The invention relates to the technical field of road safety protection equipment, in particular to an elevated railway roadside protection device. Background technique [0002] With the vigorous development of my country's railway construction, train safety has become an urgent problem to be solved. Once a train derailment accident occurs, it will inevitably cause huge casualties and property losses. At present, according to the experience of foreign railways and research results at home and abroad, protective walls are generally used in elevated railways, so that trains can slide along the protective walls in case of derailment, so as to prevent secondary accidents caused by train overturning or off-line. A reasonable setting of the protective wall can prevent the train from going off-line, but it cannot effectively absorb the impact kinetic energy of the derailed train, because the impact force between the train and the protective wall is very large...
