In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides an assembled highway anticollision barrier, the concrete stand more than two, the mounting groove has been seted up symmetrically to the both sides of concrete stand, installs combination formula concrete anticollision board between the mounting groove of adjacent concrete stand, combination formula concrete anticollision board includes an upper portion concrete anticollision board, more than middle part concrete anticollision board and a lower part concrete anticollision board, all connect into integral type structure through tenon fourth of twelve earthly branches mode between upper portion concrete anticollision board and the middle part concrete anticollision board, between the adjacent middle part concrete anticollision board and between middle part concrete anticollision board and the lower part concrete anticollision board.
Furthermore, the bottom of the upper concrete anti-collision plate is provided with a mortise slot, the top and the bottom of the middle concrete anti-collision plate are respectively provided with a tenon and a mortise slot, and the top of the lower concrete anti-collision plate is provided with a tenon.
Furthermore, foundation bolt holes are uniformly distributed in the top of the concrete upright column, and high-strength bolts penetrate into the foundation bolt holes.
Further, an asphalt pavement layer is laid at the bottom of the lower concrete anti-collision plate.
Furthermore, a group of penetrating elliptic cylindrical bolt holes are formed in two sides of the mounting groove, circular bolt holes are formed in two ends of the upper concrete anti-collision plate, the middle concrete anti-collision plate and the lower concrete anti-collision plate, and high-strength bolts penetrate into the elliptic cylindrical bolt holes and the circular bolt holes.
Since the technical scheme is used, the utility model discloses an advantage has below:
1. the utility model discloses used material mainly is the concrete, and manufacturing cost is lower, and used concrete anticollision board and concrete stand simple structure, the preparation is easy, through field assembly, has saved cast-in-place construction step, shortens construction cycle greatly, improves the efficiency of construction, reduces the cost. Wherein combination formula concrete anticollision board adopts mortise-tenon joint to utilize high strength bolt and concrete stand to assemble, joint strength is high, and overall stability is strong, can effectively resist the impact of vehicle, has reduced the whole risk of toppling of whole anticollision barrier.
2. The utility model discloses set up rag bolt hole on the concrete stand, simultaneously pre-buried high strength bolt on the ground firmly fixes the concrete stand on the ground through high strength bolt, makes anticollision barrier main part and ground effectively fixed to avoided the device to take place the skew in the use, and the installation butt joint required precision is not big, the on-the-spot assembly of being convenient for.
The utility model discloses the installation, dismantle conveniently, after the vehicle striking, the damage usually is concrete anticollision board moreover, and adjacent concrete anticollision board adopts tenon fourth of the twelve earthly branches mode to connect, can directly dismantle and change after certain concrete anticollision board damages, and the concrete stand can continue to use, effective material saving, reduction maintenance cost.
