Curved spring and foam pad can form effective anticollision system, and when vehicle imprudence collides device body, bumper post can
First time buffered is done using foam pad, bend-resistance spring is subject to a degree of bending when impact force is excessive, during its deformation
Between it is more rapid, the power of bounce-back can be absorbed by foam pad again, so the distance of vehicle bounce-back can also greatly reduce, so as to prevent
Secondary collision occurs with rear car.
Advantage 2：The special anticollision barrier of bridge, night prompting device include lithium battery, alarm flashing lamp and waterproof patch, and lithium
Battery is electrically connected with alarm flashing lamp, and waterproof patch is bonded with beam arm.It is equipped with by the night prompting device of setting by lithium electricity
The alarm flashing lamp of pond control, the left and right range of exposures of underlit vehicle car light may be less than normal, so night prompting device energy
Enough internal photo resistance adjoint in the case of for direct current send the warning light that red blue flash sparkles, so as to remind underlit
Vehicle, while waterproof patch can be convenient for changing and dismantle, and greatly facilitate maintenance and repair usually.
Advantage 3：The special anticollision barrier of bridge, the surface of bumper post and the side of beam arm are equipped with equally distributed reflective
Patch, and reflection plaster is bonded with bumper post and beam arm respectively.By setting reflection plaster to greatly enhance the note of driver at night
Meaning power, plays good prompting effect, if it happens collides and collision dynamics is superpower, be connected between splice plate, while bottom
Plate can be inserted into underground by positioning bolt hole, so the offset possibility that device body occurs is smaller, once bumper post severs
Backboard on rear side of beam arm can play further iris action, and carrying out pocket to vehicle using steel bar and wire netting blocks, and prevents car
Pour in water.
