Embodiment Construction

[0015] like figure 1 As shown, the pier anti-collision device of the present invention includes a reinforced concrete slab 1 with two-way structural steel bars 2 inside; it also includes at least one vertical H-shaped steel 4 and at least two horizontal H-shaped steels 3;

[0016] The vertical H-shaped steel 4 is at the same height as the reinforced concrete slab 1, and is evenly distributed vertically on the side of the reinforced concrete slab 1 facing the rockfall. like figure 2 shown. Make the vertical H-shaped steel 4 be positioned on the path where the falling rock strikes, so that it directly contacts with the falling rock. The vertical H-shaped steel 4 is detachably fixedly connected to the reinforced concrete slab 1;

[0017] The two horizontal H-shaped steels 3 are symmetrically placed on both sides of the vertical H-shaped steel 4, and are detachably fixed on the transverse midline of the reinforced concrete slab 1. The sides are flush.

[0018] The vertical H...

Abstract

The invention discloses an anti-collision device for a bridge pier. The anti-collision device is good in rockfall impact resistance and crack resistance. The anti-collision device for the bridge pier comprises a reinforced concrete slab (1) internally provided with bidirectional constructional steel bars (2). The anti-collision device further comprises at least one piece of vertical H-shaped steel (4) and at least two pieces of transverse H-shaped steel (3). The vertical H-shaped steel (4) is as high as the reinforced concrete slab (1), is vertically and uniformly distributed on one side, facing rockfall, of the reinforced concrete slab (1), and is detachably and fixedly connected with the reinforced concrete slab (1); the two transverse H-shaped steel (3) are symmetrically arranged on the two sides of the vertical H-shaped steel (4) and detachably fixed to the transverse center line of the reinforced concrete slab (1), one end of the transverse H-shaped steel (3) abuts against a side wing of the vertical H-shaped steel (4), and the other end of the transverse H-shaped steel (3) is flush with the side edge of the reinforced concrete slab (1).

Description

technical field [0001] The invention belongs to the technical field of bridge piers, in particular to an anti-collision device for bridge piers. Background technique [0002] Rolling stone disasters are common natural disasters in mountainous areas. With the rapid development of my country's transportation industry, highways continue to move towards mountainous areas, and bridges, as pivotal projects connecting lines, are often harmed by rolling stones. Especially in areas prone to geological disasters such as earthquakes and mountain torrents, when slopes are damaged after earthquakes or floods, secondary rolling stone disasters often occur, causing bridges in the area to be damaged or even collapsed. [0003] Rockfall anti-collision measures include rock-blocking fences, protective nets, rock-blocking walls, semi-rigid rock-blocking walls, rockfall troughs, etc., but there are some limitations. For example, the old steel rails are used as the columns for the stone fence, ...
