Embodiment Construction

[0020] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0021] refer to figure 1 and 2 As shown, a flood control system with a flat double-opening arc gate on the bottom rail includes a gate structure 1, a hoist 2, and a door storehouse 3. The gate structure 1 is a plane double-opening arc-shaped gate structure, and the gate storehouse 3 are symmetrically distributed on both sides of the river channel and are used to accommodate part of the gate structure 1, the hoist 2 is connected to the gate structure 1 and controls the gate structure 1 to realize the opening and closing of the gate; the hoist 2 is Type hoist; In this embodiment, the hoist 2 is a 60kN fixed hoist hoist, and the hoist 2 controls the operating angle of the gate structure 1 to be 58.35°;

[0022] The gate structure 1 includes an arc gate 11 , main arms 12 of at least two triangular truss structures, lattice connecting r...

Abstract

The invention discloses a flood control system with a bottom rail plane double-open arc gate. The flood control system comprises gate structures, an opening / closing machine and gate chambers; the gate structures are plane double-open arc gate structures; the gate chambers are symmetrically distributed on two sides of a river channel, and are used for accommodating the gate structures; the opening / closing machine is connected with the gate structures, and controls the gate structures to realize gate opening / closing; and the opening / closing machine is a windlass opening / closing machine. The flood control system is more suitable for all hydraulic engineering with water head differences and large river channel widths and unsuitable for setting fixed water stages, and is high in butt joint precision, excellent in water stop effect, convenient for maintenance and long in service life.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a flood control system with flat double-opening arc gates on bottom rails. Background technique [0002] The development and selection of the gate engineering structure is very important in the flood control system. At present, the gate engineering structures commonly used in large-scale flood control systems at home and abroad are generally floating body doors, pontoon doors, lying doors, hanging doors, fan-shaped revolving doors, mirror doors, and pontoon plane arc doors. However, the engineering structure of these gates cannot meet all the head differences, the channel width is large (not less than 90 meters), it is not suitable to set a fixed water level, there are no hydraulic structures that hinder navigation in the channel, and the gates have a flow rate greater than 60 cubic meters during the control period. m / s capacity. Therefore, considering the...
