Problems solved by technology

[0003] However, there are still defects in the existing technology: because the strip-shaped safety restraint belt provided on the side of the rubber air bag facing away from the upstream is only used as an auxiliary traction device, the water-retaining steel plate is held back due to wind pressure and other reasons.
[0004] There are also defects in the existing rubber airbags at present: the general rubber airbag is a capsule body with only a single air chamber. It is difficult to repair, and more importantly, because all the steel guard plates are lying down, the huge water body stored in it gushes out, and the downstream personnel and property are too late to transfer, which may cause irreparable losses
However, in actual situations, due to uncontrollable climate and rainfall, the water storage capacity ...

Embodiment approach 1

[0040] Embodiment 1, refer to the attached figure 2 , 3 , 5-10

[0041] Build side walls 3 on both sides of the cross section of the inland river intersection, the width between the two side walls 3 is 20 meters, and the width of the bottom of the river between the two side walls 3 is poured with a concrete foundation 2 with a width of 20 meters. Two dam bodies 1 are equidistantly installed on the foundation and between the side walls. Each dam body 1 has an airbag 300 that can rise and collapse when inflated and deflated. The material is rubber and the width It is 9.8 meters, and its cross-section is a lying equilateral triangle when it is fully inflated. The angle of the top angle is 60°. According to the claim, the angle of the top angle is close to the concrete foundation. The angle of the two bottom angles is also 60°, and the length of the two sides is 4.8 m; above the airbag, corresponding to the upstream direction, the first water retaining plate 100 that can cover ...

Embodiment approach 2

[0042] Embodiment 2, refer to the attached figure 2 , 3a , 5-10

[0043] Others are the same as Embodiment 1, except that the airbag 300 on the right side of the first water deflector 100 is composed of a first air chamber 310 and a second air chamber 320 with independent inflation / exhaust ports, and the air chambers are stacked up and down. place.

Embodiment approach 3

[0044] Implementation mode 3, see attached figure 2 , 4 , 5-10

[0045] Others are the same as Embodiment 1, except that the second water retaining plate 400 with the flexible turning portion 430 is used instead of the second water retaining plate 410 connected to the second lower water retaining plate 420 through the flexible connecting plate 200 Plate 400.

Abstract

The invention provides a two-way water-blocking gas shield dam which comprises a dam body arranged on the concrete foundation and arranged between two side walls. The dam body comprises more than one combined gas shield dam single body. The two-way water-blocking gas shield dam is characterized in that the gas shield dam single body comprises a first water-blocking plate, a second water-blocking plate with the same width as the first water-blocking plate, and a gas bag located between the first water-blocking plate and the second water-blocking plate, the upper end of the first water-blocking plate is connected with the upper end of the second water-blocking plate, the lower end of the first water-blocking plate and the lower end of the second water-blocking plate are connected to the concrete foundations through anchoring pieces, and the middle of the second water-blocking plate can be folded. Compared with the prior art, the two-way water-blocking gas shield dam can effectively prevent the gas bag from being exposed to the weather so as to prevent aging, the safety and durability of the gas shield dam system are greatly improved, the closed structure can protect the gas bag against manual damage, and maintenance cost and security cost can be reduced as well.

Description

technical field [0001] The invention relates to projects related to the control and utilization of streams, river courses, coasts or other sea areas, in particular to an air shield dam using an inflatable rubber air bag to support the dam body and a fishway based thereon. technical background [0002] Existing gas shield dams see figure 1 : Including a water-retaining steel plate with a certain radian: 1', the bottom end is provided with a fixing piece 6', there is no rubber air bag 3' on one side of the water-retaining steel plate 1', and one end of the strip safety restraint belt 2' is connected to the water-retaining The steel plate is connected, and the other end is provided with a fixing part 4', and the inflation / exhaust port 5' of the rubber air bag is connected with the control system. The rubber air bag 3' is inflated and exhausted through the inflation / exhaust port 5' to make the steel guard rise and fall to maintain a specific water level. And it can realize the...
