Description of the Invention (4) The guiding portion 21 is preferably a convex lip. As shown in the third and sixth figures, in addition, the water guiding and anti-scouring device 2 of the present invention comprises at least one or a plurality of bridge piers on the bridge, whereby the number of water guiding and anti-scouring devices 2 can be set according to the amount of water flowing. Give the best water guiding effect. In the first embodiment, the water guiding and anti-flushing device 2 is convexly protruded from the pier 1 , so the first embodiment can still include two methods. The first one is to guide the water guiding and anti-scouring device of the present invention when the bridge is erected. 2 and the pier 1 is integrally formed at the same time; the second is that the pier 1 and the water guiding and anti-flushing device 2 are respectively fabricated, and then the water guiding and anti-scouring device 2 is combined on the pier 1. The second method is also very suitable for use on old bridges to prevent the old bridge from being eroded by water. The width of the water guiding and anti-scouring device 2 of the present invention does not need to be large, and it is only necessary to prevent the water flow B from contacting the bridge B and the downward jet B 2 . When the width of the water guiding edge is too large, its strength and ability to withstand impact are relatively weak, and the manufacturing cost is high. In order to let the review committee know clearly, 'the case has enlarged the proportion of the water-proof anti-scour device 2 in the eighth to eleventh figure, so that the structure is clearer and clear at a glance. Through the above description, the "water-proof and anti-scour device for bridge piers and the bridge and bridge pier using the water-conducting anti-scour device" of the present invention, by means of the innovative water-proof anti-scour device, can effectively make the water flow be effectively Guide upwards to prevent the earth and stone in the riverbed from being washed away, to prevent the bottom of the pier from being hollowed out to form a dangerous bridge to ensure the safety of the user's life and property.
