Steel dam gate in dock

Abstract

The invention relates to a steel dam gate in dock engineering, and belongs to the technical field of backwater gate structure. The steel dam gate is mainly characterized in that the gate is designed into a triangular prism structure; a water baffle plate is fixed on one lateral surface of the triangular prism subjected to water pressure; compared with the prior structure with a rectangular section or a trapeziform section, the structure saves about half materials and has good stability, and the structure self utilizes stability of a triangle, so that the structure is concise and stable; and the structure is triangular in whole, so the integral stability of the gate is ensured by utilizing pressure of water columns when the whole structure is subjected to water pressure. The steel dam gate breaks through the limitation of the prior dock gate design, and utilizes the principle of stability of the triangular structure to ensure that the structure is concise and smooth, has definite stress and saves the materials greatly; moreover, under the condition of lighter self weight of the structure, water retaining weight, instead of stowage increase, is smartly used as ballast, so as to ensure the integral stability of the structure.

Description

technical field [0001] The invention relates to a steel dam gate in a dock, belonging to the technical field of water retaining gate structures. Background technique [0002] The water retaining gates that are often used in the dock gates (30-106m) of existing large-orifice dry docks or slipways generally include: buoyant box gates, simply supported gates with legs and other laterally supported force-bearing gates. [0003] The pontoon-type gate has a rectangular or trapezoidal cross-section. It needs to be equipped with a considerable amount of heavy aggregate concrete or cast iron blocks to ensure the stability of the dock gate during opening and floating. Several ballast water tanks need to be installed to ensure The dock gate can effectively sink and float, and a large number of ventilation, water pipelines and circuits are arranged. There are many cabins (fixed ballast tanks, ballast water tanks, operating cabins, tidal tanks), the assembly process is complicated, and ...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a steel dam gate in the dock, which solves the bulky and complicated operation of the existing pontoon-type dock gate, and solves the shortcomings of the dock gate with legs such as low rigidity, irregularity, and long operating time. , Eliminate engineering safety hazards
