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

Example Embodiment

[0045] Example 1

[0046]The ecological air bag supporting dam reference diagram of the present embodiment includes a pneumatic shield gate main body 1 composed of a water retaining shield plate A1 and a supporting air bag QN, and the pneumatic shield gate main body 1 is provided with a dam height for adjusting the height of the dam The limit device 2 is adjusted, an aeration device 3 for removing sediment in front of the dam is provided in front of the dam, and a biological channel 4 is provided at the bottom of the dam. The main body 1 of the pneumatic shield gate includes a water-retaining shield A1 anchored on the base plate A3 and a supporting airbag, and the water-retaining shield A1 is connected to the water-retaining shield A1 through a soft connector A4 made of a rubber material filled with a fiber skeleton. The base floor A3 is softly connected, and the supporting airbag includes a first airbag A2-1 and a second airbag A2-2 located between the first airbag A2-1 and t...

Example Embodiment

[0047] Example 2

[0048] The difference between this embodiment and embodiment 1 is that

[0049] The main body of the pneumatic shield gate includes a water-retaining shield B1 anchored on the base plate B3 and a supporting airbag, and the supporting airbag and the water-retaining shield B1 are anchored on different anchor lines; the water-retaining shield B1 is rigidly connected to the basic base plate B3 through a hinge B4, and the number of the supporting airbags is two, one is the first airbag B2-1, the other is the second airbag B2-2, and the first airbag B2 -1 and the second airbag B2-2 are anchored on the same anchoring wire. The water-retaining shield B1 includes a shield body, which is composed of a base layer and an anti-corrosion layer coated on the base layer; the bottom of the shield body and the contact part with the airbag are changed to be smooth The columnar structure solves the problem of the water retaining shield’s wear on the airbag; the anticorrosion ...

Example Embodiment

[0050] Example 3

[0051] The difference between this embodiment and embodiment 1 is that

[0052] The main body of the pneumatic shield gate includes a water-retaining shield C1 anchored on the base plate C3 and a supporting airbag, and the supporting airbag and the water-retaining shield C1 are anchored on different anchoring lines. The water retaining shield C1 is flexibly connected to the base base C3, and the supporting airbag includes a first airbag C2-1 and a second airbag C2-1 located between the first airbag C2-1 and the water retaining shield C1. The airbag C2-2; the first airbag C2-1 and the second airbag C2-2 are independently anchored on different anchoring lines inside the water retaining shield C1.

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...
