As shown in fig. 5, the transverse support 3 is formed by welding three transverse support tubes 8 and three connecting tubes 9, wherein the three connecting tubes 9 connect the three transverse support tubes 8 two by two respectively, so that the transverse support 3 forms a triangular structure matched with the three upright posts 2, the integrity of the transverse support 3 is improved by the connecting rods 9, and the structural strength of the transverse support 3 is further improved. The inner diameters of the tube holes of the three cross supporting tubes 8 are matched with the column diameter of the upright column 2, so that the cross supports 3 can be sleeved on the upright column 2 through the cross supporting tubes 8 and detachably mounted and fixed on the upright column 2 through the bolt assemblies 4, and field mounting and later maintenance are facilitated.

As shown in fig. 2, the transverse supports 3 and the anti-collision blocks 1 are arranged at intervals in the height direction of the upright column 2, two anti-collision blocks 1 are arranged between the two transverse supports 3, and the two anti-collision blocks 1 are fixed between the two transverse supports 3 in a limiting manner to ensure the firm structure of the anti-collision blocks 1, so as to ensure the protection effect on the pier 10 when the anti-collision blocks are impacted by a vehicle.

Referring to fig. 2, the present embodiment, when in use, includes the following construction steps:

1) at a certain distance from one side of the fortifying pier 10, the three upright posts 2 are vertically driven into the foundation one by one, and the three upright posts 2 are in a triangular arrangement structure.

2) The bottom transverse support 3 is sleeved on the upright post 2 in a penetrating way by utilizing the tube hole of the transverse support tube 8, and the transverse support 3 is connected and fixed with the upright post 2 through the bolt component 4.

3) Two anti-collision blocks 1 are sleeved on the upright post 2 in a penetrating way by using through holes 11 and are arranged above the transverse support 3 at the bottom. Then, a middle transverse support 3 is arranged above the two anti-collision blocks 1 in the same way. At this time, two side surfaces of the triangular anti-collision block 1 are inclined surfaces, and a vehicle is guided by adopting a flow guiding principle, so that larger impact energy generated during collision of the vehicle is dissolved, and the damage of the vehicle is reduced to the maximum extent.

Similarly, if an anti-collision pier with a relatively low height is needed, a group of anti-collision blocks 1 and the transverse supports 3 can be directly detached or the number of the anti-collision blocks 1 between two adjacent transverse supports 3 can be reduced.
