A bridge leg depth stopper

Abstract

The invention relates to the field of Yellow River flood control and emergency equipment, in particular to a bridge leg depth limiter used for preventing settlement and instability of emergency bridges, and the IPC classification number is E02B1 / 00. The limiter Includes fixing block, spring, movable block, Fastening nut, upper disk, Center turntable, fastening nails and pivot pin, The movable block and the middle turntable are arranged in the groove corresponding to the lower plate, the front inclined surface of the limit short arm of the middle turntable and the front inclined surface of themovable block are matched, so that the bridge leg depth limiter is in a waiting-to-be-locked state, the upper plate is arranged on the lower plate, the upper plate is connected with the lower plate through a rotating shaft pin, and the movable block is limited between the upper plate and the lower plate through fastening nails. When the free bridge leg is installed, the leg depth limiter of the invention can be directly stuck at the reserved position of the bridge leg as a unit accessory, and can be used for emergency rescue and disaster relief operations at levee and dam crevices, thereby solving the problems of low load bearing capacity and inclined instability of the free bridge quickly built during the emergency rescue and disaster relief.

Description

technical field [0001] The invention relates to the field of emergency rescue equipment for flood control of the Yellow River, in particular to a bridge leg depth stopper for preventing settlement and instability of a bridge body due to load bearing, and its IPC classification number is E02B1 / 00. Background technique [0002] River breaches are very harmful. For example, in 1998, catastrophic floods occurred in my country's Yangtze River, Songhua River and other rivers, which brought huge economic losses and casualties to the cities and counties around the river. Although the final breach is blocked by adopting the current blocking breach technology. But because it requires personnel to stand in the torrent to drive piles, the price paid is also extremely heavy. Therefore, the high-efficiency and safe blocking of breach features of the bridge-type emergency rescue and disaster relief method has changed the situation of the existing construction technicians for blocking cons...
