Pier fluid anti-collision device

Abstract

The pier fluid anti-collision device includes the main body of the pier, the main body of the anti-collision device, the anti-collision steel pipe, the protective layer, the water-permeable energy-consuming block, and the composite floating body. Composite floating body; the main body of the anti-collision device includes an inner shell, an anti-collision steel pipe, a protective layer, a water-permeable energy-dissipating block, and an external shell. The inner layer of the innermost water permeable energy consumption block is provided with an inner casing, and the outer layer of the outermost water permeable energy consumption block is provided with an outer casing. The beneficial effects of the present invention are: since the impact of small boats on the pier is generally concentrated on the water surface, when the device is in use, the composite material floating body is connected to the main body of the anti-collision device, so that the main body of the anti-collision device floats on the water surface, and the main body of the anti-collision device floats on the water surface. It automatically rises and falls, so the position of the protected pier changes with the water level.

Description

technical field [0001] The invention relates to the technical field of water building safety protection, in particular to a bridge pier fluid anti-collision device. Background technique [0002] With the continuous development of the transportation industry, a large number of cross-sea and cross-river bridges are constantly being built. Most of the rivers and seas where such bridges are located are busy waterways, and the conditions such as currents, waves, wind and waves are complicated, and the bridge inevitably bears a certain risk of ship collision. Relevant studies have been carried out at home and abroad, and the ship-bridge collision theory has been proposed, and some bridge protection facilities have been designed. The fundamental purpose of bridge anti-collision is to prevent the structural damage of the bridge caused by the collision force of the ship exceeding the design bearing capacity of the bridge pier on the one hand, and to protect the ship as much as possi...
