Ecological air bag supporting dam

Abstract

The invention relates to an ecological air bag supporting dam which can meet urgent needs of modern water conservancy project construction and transformation, and belongs to the technical field of movable gate dam structures. The ecological air bag supporting dam comprises a pneumatic shield-shaped gate body which is composed of a water retaining shield plate and a supporting air bag, the ecological air bag supporting dam is characterized in that a dam height adjusting and limiting device is arranged on the pneumatic shield-shaped gate body and used for adjusting the dam height, an aerating device is arranged in front of the dam and used for clearing sediment in front of the dam, and an organism channel is formed in the bottom of the dam. The ecological air bag supporting dam has the advantages of being complete in structure, ecological, environmentally friendly and high in corrosion resistance.

Description

[0001] technical field [0002] The invention relates to an ecological airbag-supported dam capable of meeting the urgent needs of modern water conservancy project construction and transformation, and belongs to the technical field of movable dam structures. Background technique [0003] With the development of water conservancy technology, many new products and technologies of water-retaining structures, such as rubber dams, hydraulic steel gates, hydraulic lifting dams, pneumatic shield dams, etc., can be lifted and adjusted to varying degrees. , full dam collapse and flood discharge, and operational safety are gradually improving, increasingly meeting the needs of water conservancy project construction. However, in the existing movable sluice dam technology, the consideration of ecological and environmental protection is seriously lacking, and the following problems generally exist: [0004] 1. For the dam type that uses hydraulic oil for system control and support, th...

AI Technical Summary

Problems solved by technology

[0004] 1. For the dam type that uses hydraulic oil for system control and support, there will be leakage, run-off and leakage of hydraulic oil during installation, use and maintenance, which will cause environmental protection problems of secondary pollution of water quality

[0005] 2. For projects that must solve the ecological problems of the water system, the existing sluice dam technology often can only set up a special biological channel outside the system

Due to the complex engineering structure and high engineering cost of external special biological channels, it is often impossible to implement, thus causing most of the built sluice dam systems to have no biological channels for life

[0006] 3. For gate dams made of metal materials, there are common defects of high cost, poor corrosion resistance, and high maintenance costs

[0007] 4. Existing movable gate dam technologies, including new hydraulic lifting dams, pneumatic shield dams, etc., have not achieved continuous dam height control, or can only use node control for dam height

[0008] 5. The existing pneumatic shield gate fixes the water-retaining shield and the supporting airbag on the same anchoring line. Although the structure is simple, the force of the anchoring parts is complicated, and the strength of the anchor and the strength of the foundation are extremely high.

[0009] 6. Most of the existing movable gate and dam technologies lack effective control over the bottom sediment and bottom water body in front of the dam, especially in the dry season. The deterioration is serious, which has a great impact on the survival of organisms; in addition, there is no effective way to freeze and break the ice in winter in front of the dam
