Embodiment Construction

[0016] figure 1 Among them, the gravity anchor (2) is placed on the top platform of the solid pier (3), and the arresting cable (1) is tied to the gravity anchor (2). The minimum height of the arresting cable (1) to the water surface should be greater than the maximum height of the fortified bow and stern, and should be less than the height of the buildings on board. Arresting cables (1) If high-strength steel strands or parallel steel cables are used, the same anti-corrosion measures as those used in bridges should be taken; if composite materials are used, they should be replaced regularly according to the aging resistance of the materials. Parameters such as the distance between two adjacent solid piers (3), the bearing capacity of the arresting cable (1), the weight and external dimensions of the gravity anchor (2) should be reasonably designed according to the anti-collision requirements. The top surface of the solid pier (3) shown in the figure is higher than the water ...

Abstract

The invention relates to an elevated dragging energy eliminating type ship blocking system for preventing ship collision of a bridge, which consists of a blocking cable, gravity anchors and a platform or a blocking cable and gravity anchors with support legs, wherein the blocking cable is higher than the water surface; and the platform is used for placing the gravity anchors. The height of the blocking cable is higher than the maximal height of a bow and a stern but lower than the height of a structure object on the ship. In order to lift the blocking cable, the tops of the gravity anchors are provided with brackets or additionally provided with auxiliary piles. In order to prevent the condition that the gravity anchors are embedded and can not be dragged due to sand deposition, the gravity anchors are arranged on the platform with certain height or the bottom of the gravity anchors are provided with the support legs. When the ship impacts the blocking cable, the blocking cable and the gravity anchors at both ends of the blocking cable are driven to move to the bridge location; and the kinetic energy of the ship is consumed in the dragging process. The interaction force and the dragging distance between a collision preventing system and the ship are designed according to the concrete conditions of set ship tonnage, ship speed, flow speed, wind speed and the like; and the elevated dragging energy eliminating type ship blocking system not only can protect the bridge but also can be beneficial to lightening the loss of the ship.

Description

technical field [0001] The invention relates to an engineering anti-collision system for ships blocked by bridges and other important structures. Background technique [0002] At present, known bridge anti-ship collision systems mainly contain two types. [0003] The first type is set on the pier, which uses the deformation of the anti-collision system to absorb the kinetic energy of the ship and prolong the time of the collision, thereby reducing the impact force of the ship. This type of anti-collision system is technically complex and expensive. Once a ship collides, although it can protect the safety of the bridge piles, it has little effect on the protection of the ship, and the recovery cost is relatively high. [0004] The other type is set at a certain distance from the side of the ship from the non-navigation hole. Such as invention patent ZL200510095592.0 and utility model patents ZL200620025697.9, ZL201020138761.0, ZL201020697102.0 disclosed anti-collision syst...
