The utility model relates to a
flood prevention lock gate
pier technical field especially is a kind of superhigh combined lock gate
pier, including
retaining wall, installation space is formed between two adjacent retaining walls;Bottom baffle, vertically set in the installation space, two ends of the bottom baffle are connected with two retaining walls respectively, and bottom end of the bottom baffle is installed on ground;Top baffle, vertically set in the installation space, the bottom of the top baffle is fixedly connected with the top of the bottom baffle by pressing top piece;Buffer plate, hinged in the top of the top baffle;Support frame, support between the backwater surface of the bottom baffle and the top baffle and ground;Float, set on the buffer plate, it can make the buffer plate part float on water surface.The utility model reduces material cost and construction cost, shortens construction cycle simultaneously;At the same time, water surface floating object can be prevented and directly collides top baffle, improves the
impact resistance of entire combined lock gate
pier.
