The highway engineering bridge concrete anti-collision guardrail template structure according to claim 1 is characterized in that: A placement seat (38) is rotatably mounted on the top of the outer template (3) and the inner template (2); a top plate (39) is rotatably mounted on the top of the placement seat (38); a connecting plate (40) is mounted on the inner side of the top plate (39); a magnetic plate (41) is mounted on the right side of the placement seat (38); the magnetic plate (41) is adsorbed to the connecting plate (40); a cross bar (42) is arranged on the inner side of the placement seat (38) and the top plate (39); and a limiting frame (43) is mounted on the bottom of the cross bar (42).

9. The highway engineering bridge concrete anti-collision guardrail template structure according to claim 1 is characterized in that: A second fixing plate (44) is installed on the left side of the outer template (3), a rotating rod (45) is threadedly installed on the bottom of the second fixing plate (44), a supporting seat (46) is installed on the top of the rotating rod (45), and a sliding seat (47) is installed on the right side of the supporting seat (46).

10. A method for constructing a concrete anti-collision guardrail formwork for a highway engineering bridge, applicable to a concrete anti-collision guardrail formwork structure for a highway engineering bridge as described in any one of claims 1 to 9, characterized in that: The steps include: S1: Installation; by using an ink fountain to pop out the positioning line and the positioning rib position of the inner template (2), the installed positioning rib is used to limit the inner template (2), and the inner template (2) is pressed against the square wood (25), so that the inner template (2) can be installed, and the double-sided tape is pasted on the contact surface of the outer template (3) and the outer edge of the side beam wing plate, and the outer template (3) and the side beam wing plate can be tightly fitted by the pull rod at the bottom of the template to prevent leakage, and then the outer template (3) is lifted by a car crane, and the crane continues to lift the outer template (3); S2: Balance correction; pass the hanging tube (8) through the first fixing frame (6) and the second fixing frame (7), and lift the outer template (3) by pressing the hanging tube (8) so that the height of the outer template (3) and the inner template (2) are maintained at the same level, and fill the uneven ground of the inner template (2) with foam glue.
