s1, placing the two support beams (4) at an included angle of 90 degrees, welding and fixing the support beams (4) and the main support columns (6) again through the fixed cross beam (13), penetrating the support beams (4) through the dewatering plate (7), and finally bonding the bottom ends of the support beams (4) and the adapter plate (3);
s2, when raining, rainwater can be blocked by the toughened glass (14) and is discharged to the outer side of the toughened glass (14), and the outer side of the toughened glass (14) protrudes one meter out of the guardrail (8), so that the rainwater can be blocked and discharged under the rainwater with violent wind direction, and the aim of avoiding rainwater accumulating on the bridge floor (1201) is fulfilled;
s3, when rising tide, rivers are more torrential, because the board (7) bottom of anhydrating is provided with the radian, and the radian is 90, can obtain according to the frictional force principle that rivers can be less than the resistance at board (7) top of anhydrating at the resistance that board (7) bottom received of anhydrating, final rivers can not blockked and directly flow away by bridge floor (1201) of bridge, such design can reduce the resistance of bridge floor (1201) to rivers, thereby make rivers flow away fast, and then not only improved the dewatering ability of bridge floor (1201), the ponding of large tracts of land appears in bridge floor (1201) when still preventing rising tide.
