Floating rubber dam

Abstract

The invention relates to a floating rubber dam. The floating rubber dam comprises a floating box, and a dam bag; wherein the floating box is used for being placed at the bottom of water, the side wallof the floating box is provided with a filling and discharging pipe, the top of the floating box is provided with a ventilation pipeline, and the ventilation pipeline extends out of the water surface; and the dam bag is connected to the top of the floating box. According to the floating rubber dam, the floating box sinks by filling water in the floating box through the filling and discharging pipe; the water can be injected into the dam bag to enable the dam bag to be inflated to control water flow, and the water in the dam bag is discharged through the filling and discharging pipe to enablethe dam bag to be shrunk, so that navigation is restored; and the floating rubber dam is not limited by construction conditions, replacement and maintenance are convenient, and the damage or influenceon surrounding buildings caused by construction excavation is reduced.

Description

technical field [0001] The invention belongs to the technical field of water conservancy river regulation, and more specifically relates to a floating rubber dam. Background technique [0002] At present, the structure of large-scale water conservancy gates at home and abroad generally adopts floating body doors, floating box doors, lying down doors, hanging doors, fan-shaped revolving doors, mirror doors, floating box doors, plane arc doors, etc. Each gate type has its own characteristics, and the corresponding gate type will be selected after considering factors such as project location, construction conditions, maintenance, operation management requirements, and navigation. It is not suitable to set a fixed water level for a navigable river with a water head difference, a large width, a river that cannot be suspended for construction, or a river with restricted excavation on both sides of the river and where flood control or water diversion control buildings need to be in...

AI Technical Summary

Problems solved by technology

It is not suitable to set a fixed water level for a navigable river with a water head difference, a large width, a river that cannot be suspended for construction, or a river with restricted excavation on both sides of the river and where flood control or water diversion control buildings need to be installed. On the one hand, the construction of the water conservancy gate project is difficult, on the other hand, the fixed water conservancy gate affects the landscape and navigation, and it is difficult to maintain and replace it.
