By the way that rubber sleeve is fixedly installed on metal sleeve, rubber sleeve has elasticity, plays better cushioning effect.
By being whole, and all roller type pile body units by horizontally disposed Interal fixation by all column lower parts
Foundation pile be embedded to underground, and be connected as entirety through concrete substrate, improve structural stability.
It is further improved, the spacing of the adjacent rollers formula pile body unit is 30cm.Spacing is too small, then of high cost；Spacing
Excessive, then vehicle easily passes through gap or is stuck in gap, and protection effect is poor.
It is further improved, the foundation pile is steel pipe, and outer diameter 245mm, wall thickness 12mm, intensity is high, will not be because of generation
It hits and deforms, is broken.
It is further improved, the foundation pile upper end edge peripheral surface homogeneous vertical is provided with multiple second deep floors, and second adds
The top and the bottom surface of foundation pile ring flange of strong floor are welded to connect, and improve ring flange intensity.
It is further improved, the peripheral surface upper edge of the column is circumferentially provided with multiple first grooves, the inner wall of metal sleeve
Corresponding position is circumferentially also equipped with multiple second grooves, and the first groove, the second groove are equipped with, and active card sets more in groove
A ball.By increasing groove, ball, increase rotation flexibility.
Compared with prior art, the utility model has the beneficial effects that：
1), after vehicle such as casts anchor at the accidents, in shock after protective fence, impact force along guardrail length direction component,
And the frictional force between vehicle and guardrail causes metal sleeve to rotate, after so that vehicle is slowly slided one end distance forward
Stop, reducing and hit momentum, reduce accident damage, avoids that secondary impact accident occurs.
2), by the way that foundation pile and column are used flanged joint, facilitate installation, replace；Foundation pile height is 1.5m, length of embedment
Deep, stability is good, is not easy to topple over.
3), by the way that rubber sleeve is fixedly installed on metal sleeve, rubber sleeve has elasticity, plays better cushioning effect.
4), by being whole, and all roller type pile bodies by horizontally disposed Interal fixation by all column lower parts
The foundation pile of unit is embedded to underground, and is connected as entirety with concrete substrate, improves structural stability.
