Anti-collision pier structure and active anti-collision method

Abstract

The invention discloses an anti-collision pier structure that is characterized in that detection water spraying mechanisms are arranged on an upstream face and a downstream face of a pier correspondingly. Each detection water spraying mechanism comprises a laser range finder, a laser velocimeter and a plurality of high-pressure spray heads; a high-pressure water tank is arranged on the riverbed atthe pier and is connected with a high-pressure variable-frequency water pump which is connected with a water inlet pipe; each high-pressure spray head is connected with the high-pressure water tank through a high-pressure water supply hose, and a pressure sensor is arranged in the high-pressure water tank; a waterproof box is arranged at the top of the pier, an electric control device is arrangedin the waterproof box, and the laser range finder, the laser velocimeter, the high-pressure variable-frequency water pump and the pressure sensor are all connected with the electric control device. The invention further discloses a corresponding active anti-collision method. The invention provides an active anti-collision technology, the collision energy of a ship is gradually counteracted through water jet, the instant collision of the ship colliding with a bridge is converted into long-time water spraying collision prevention, and the acting force borne by a pier in unit time is reduced byprolonging the anti-collision action time, so that the pier is effectively protected.

Description

technical field [0001] The invention relates to the technical field of bridge engineering. Background technique [0002] The bridge structure is divided into two parts, the upper structure and the lower structure. The main body of the upper structure is the bridge deck structure, which is a structure that spans the space of the bridge and bears the gravity of the external objects on it. The substructure is a structure that supports the superstructure and transmits the force from the superstructure to the foundation. The bridge deck structure can adopt structures such as prestressed concrete hollow slabs or box girders. [0003] The substructure of the bridge includes piers, caps and pile foundations. The bridge pier is the intermediate supporting structure of a multi-span bridge, which bears the vertical force and horizontal force transmitted from the superstructure of two adjacent spans. The piers also bear wind and water pressure. [0004] In recent years, more and mor...
