Problems solved by technology

[0003] In order to overcome the lack of horizontal resistance of a single pile and the difficulty of repairing an independent anti-collision pier after being hit, the flexible pile is firstly used to withstand the impact of the ship. Under the action of the impact force, the elastic-plastic deformation of the flexible pile consumes the kinetic energy of the ship. Stakes provide horizontal support and prevent forward movement of the vessel

Embodiment Construction

[0010] exist figure 1 Among them, the flexible pile (1) is implanted in front of the pier to be protected, the gravity pier (3) is built behind the flexible pile (1), and the rubber pad (2) is installed between the flexible pile (1) and the gravity pier (3) . Fill the flexible pile (1) with clay. For cost saving, the gravity pier (3) can be formed by filling clay in the steel plate cofferdam. In order to work effectively, the gravity pier (3) should have anti-overturning ability and corresponding load-carrying capacity according to anti-collision requirements. In addition, the width of the flexible pile (1) and the gravity pier (3) should not be less than the width of the protected pier, so as to ensure that the blocked ship does not hit the pier again.

[0011] exist figure 2 Among them, in order to prevent the flexible pile (1) from sliding sideways, bolts (4) are arranged above the water surface to connect with the gravity pier (3).

Abstract

The invention discloses an anti-collision facility which is arranged before a pier and consists of a flexible pile, a gravity pier and a rubber pad. The flexible pile is arranged at the front part and the gravity pier is arranged at the rear part; the flexible pile and the gravity pier are sequentially impacted by the ship, the impact time is prolonged by the elastic-plastic deformation of the flexible pile, the impact force of the ship finally transmitted to the gravity pier is relatively small, and the excessive deformation of the gravity pier is not caused, therefore, the recovery working quantity of the anti-collision facility is small and only the flexile pile is required to be replaced.

Description

1. Technical field [0001] The invention relates to an anti-collision facility arranged in front of a bridge pier to prevent ships from colliding with the bridge pier. 2. Background technology [0002] There are two types of pier anti-collision facilities at home and abroad, one is integrated with the pier, and uses the elastic-plastic deformation of the anti-collision facilities to consume the kinetic energy of the ship and prolong the collision action time, in order to greatly reduce the impact force of the ship. Barriers are set in front of the pier to prevent ships from approaching the pier. The present invention belongs to the latter category, which is similar to setting an independent anti-collision pier in front of the bridge pier, but the difference from the independent anti-collision pier is that the present invention uses a combined device of a flexible pile and a gravity pier to withstand the impact of a ship, and mainly utilizes the elastic-plastic properties of t...
