The bridge guardrail with various blocking effects comprises pile piers, wherein a plurality of limiting grooves are symmetrically formed in the side walls of the pile piers, limiting rods are fixed inside the limiting grooves, moving blocks and springs are movably mounted on the surfaces of the limiting rods, butt joint plates are fixed on the side walls of the moving blocks, a plurality of butt joint pipe fittings are fixed on the side walls of the butt joint plates, protective pipes matched with the butt joint pipe fittings are detachably connected between the butt joint pipe fittings on the adjacent sides of the adjacent pile piers, positioning frames are symmetrically fixed on the upper surfaces of the pile piers, and blocking rods are fixed inside the positioning frames.

Preferably, the bottom of pier is fixed with the mounting panel, the lower fixed surface of mounting panel has the locating plate, be fixed with the built-in board between mounting panel and the locating plate, be fixed with the reinforcing plate between pier and the mounting panel.

Preferably, the two ends of the embedded plate and the reinforcing plate are both fixed with butt-joint plates.

Preferably, the butt joint pipe fitting includes spacing pipe and movable rod, the perforating hole of a plurality of adaptations is all seted up on the surface of movable rod and protective tube, pass through the bolt fastening between movable rod and the protective tube.

Preferably, the two end surfaces of the protection pipe are symmetrically provided with installation notches matched with the butt pipe fitting.

The beneficial effects of the utility model are as follows: this guardrail can provide different collision protection effect to oversize vehicle and small-size vehicle, to small-size vehicle, weight is less itself, kinetic energy during the motion is little, when bumping, the priority is to the absorption of energy, realize the buffer protection, to large-size vehicle, general guardrail structure can't realize the system and stop the effect, when leading to large-size vehicle out of control to bump, the vehicle directly drops down from the bridge easily, make driver's accident survival rate extremely low, in order to realize large-size vehicle's system and stop, set up built-in panel and reinforcing plate and improve guardrail structural strength, the high position sets up and blocks the pole and prevent that large-size vehicle from taking place the upset when stopping and dropping down the bridge, this device reasonable in design, safety and reliability, when carrying out bridge maintenance, the protective tube, structures such as pile mound and reinforcing plate all can be torn open and trade alone, realize the dismouting through the break-in bolt, it is convenient to maintain.

Detailed Description

Referring to fig. 1-4, a bridge guardrail with various blocking effects comprises piers 4, wherein a plurality of limiting grooves 6 are symmetrically formed in the side walls of the piers 4, limiting rods 7 are fixed inside the limiting grooves 6, moving blocks 8 and springs 9 are movably mounted on the surfaces of the limiting rods 7, butt plates 10 are fixed on the side walls of the moving blocks 8, a plurality of butt pipe fittings 11 are fixed on the side walls of the butt plates 10, protective pipes 12 matched with the butt pipe fittings 11 are detachably connected between the butt pipe fittings 11 of adjacent edges of adjacent piers 4, positioning frames 13 are symmetrically fixed on the upper surfaces of the piers 4, and blocking rods 14 are fixed inside the positioning frames 13.

The bottom of pier 4 is fixed with mounting panel 3, and the lower surface of mounting panel 3 is fixed with locating plate 1, is fixed with pre-buried board 2 between mounting panel 3 and the locating plate 1, is fixed with reinforcing plate 5 between pier 4 and the mounting panel 3.

The butt joint plates are fixed at two ends of the embedded plate 2 and the reinforcing plate 5, the position of the embedded plate 2 is determined by the positioning plate 1 before the bridge plate is poured, the embedded plate 2 is placed into a bridge steel frame, then cement pouring is carried out, the structural strength of the bridge guardrail is improved by the embedded plate 2, the anti-collision capacity of the pile pier 4 is improved by the reinforcing plate 5, and the collision of a large-sized vehicle is mainly coped with.

The butt joint pipe fitting 11 comprises a limiting pipe and a movable rod, a plurality of adaptive through holes are formed in the surfaces of the movable rod and the protective pipe 12, and the movable rod and the protective pipe 12 are fixed through bolts.

The installation breach with butt joint pipe fitting 11 adaptation is seted up to the both ends surface symmetry of protective tube 12, considers that the pre-buried position of built-in slab 2 probably appears the skew, leads to the distance location between two pile pier 4 inaccurate, sets up butt joint pipe fitting 11 and solves the installation error problem, when carrying out protective tube 12 installation, at first with the butt joint groove and the butt joint of two spacing pipe suit at protective tube 12 both ends, then promote the movable rod and remove for first butt joint hole and second butt joint hole coincide, usable bolt realization is fixed at last.

When this device uses, utilize a set of protective tube 12 to protect the small-size vehicle, when the small-size vehicle was loaded on, a set of protective tube 12 was pressed and is driven two buttcover plates 10 and move backward, and drive movable block 8 and remove extrusion spring 9, utilize the ability that spring 9 shrink absorption collision produced, realize buffer protection, for large-size vehicle, large-size vehicle's locomotive is great, driver's position is higher, when large-size vehicle out of control collides with the guardrail, utilize to block 14 realization and stop the system of vehicle, the mounted position that blocks 14 is higher, can prevent effectively that large-size vehicle from rushing out the bridge, improve driver's survival rate of accidents, this device safe and reliable.
