Abstract

A nested type top overflowing gate is mainly characterized in that a large gate leaf is in movable nested connection with a small gate leaf, and a flip bucket is arranged at the upper end of the small gate leaf in the downstream side direction, so that water flow can overflow from the top of the gate to form open weir flow, and water diversion capability can be improved while washout force is decreased; and clear upper-layer flood resources can be used to enter downstream along with main flow while bed load sediment is still blocked in an original riverway, and vibration of the gate caused by the washout force can be avoided. The nested type top overflowing gate is flexible and convenient to open and close and small in gate opening force. Meanwhile, the nested type top overflowing gate can be used normally on the basis of not changing other water gate buildings such as water gate bottom plates, gate piers and opening and closing equipment but the gate, and is less in investment, good in flood resource use effect and high in feasibility.

Description

technical field

[0001] The invention relates to a gate, in particular to a nested top overflow gate, which is suitable for storing and utilizing flood resources in rivers with many sediments and sideways. Background technique

[0002] Usually, for areas beside the mainstream or tributaries of rivers with heavy sediment, such as depressions, wetlands, bubble ponds or flood storage areas, where flood resources can be used, it is necessary to introduce flood resources to the utilization area through appropriate diversion gates, and carry out follow-up It can be used for farmland irrigation, wetland conservation, and groundwater supplementation. The gates commonly used at present are all single gates. According to its structure, it can be divided into plane gate, arc gate and so on. In the area where flood resources are utilized beside the river, the gates used are mainly common plane gates, such as plane steel gates. The planar steel gate is composed of three parts: the mova...
