Problems solved by technology

However, in this technical solution, when the shield plate is leveled, due to the technical height of the anchors (such as bolts, etc.) of the airbag, the shield plate cannot be placed horizontally in theory, and the empty airbag still has a certain volume, which will lead to If the board is placed unevenly, a hidden dam will be formed, which will affect the water flow, especially when the water flow is large (such as floods), it will affect the flow velocity

Embodiment Construction

[0016] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0017] Such as Figure 1-2 As shown, the present invention includes a concrete foundation 1, a shield plate 2 hinged on the concrete foundation 1, an airbag 3 arranged at the lower part of the shield plate 2 and driving the shield plate 2 to turn over, and the shield plate 2 is anchored Bolt one 21 is anchored on the shield plate anchoring surface, and the airbag 3 is anchored on the airbag anchoring surface by anchor bolt two 31, and the shield plate 2 and the airbag 3 are separately anchored. When the damage needs to be replaced, the anchor bolt 2 31 of the airbag can be directly unscrewed for replacement without the need to unscrew the bulky and heavy shield plate, which greatly reduces the labor intensity of airbag replacement and saves the replacement time.

[0018] The air bag 3 is provided with an air inlet, and the air inlet device of the air bag 3 is locate...

Abstract

The invention relates to a water retaining dam, in particular to an air shield dam. The air shield dam with a conveniently-dismounted and mounted air bag and a completely flattened shield plate aims to solve the problems in the prior art. The air shield dam comprises a concrete foundation, the shield plate hinged to the concrete foundation, and an airbag arranged on the lower portion of the shieldplate and driving the shield plate to perform overturning action, wherein the shield plate is anchored on a shield plate anchoring surface through an anchor bolt I; and the air bag is anchored on anair bag anchoring surface through an anchor bolt II, the air bag is provided with an air inlet, an air inlet device of the air bag is arranged in the concrete foundation, and the air bag anchoring surface is lower than the shield plate anchoring surface. The air shield dam is simple in structure, an existing air shield dam is improved, and water flow when the air shield dam collapses and overflowsis not influenced while the replacement work of the air bag is simplified.

Description

technical field [0001] The invention relates to a water retaining dam, in particular to an air shield dam. Background technique [0002] Air shield dams are one of the most commonly used retaining dams in river channels, and are widely used in daily river channel management. Such as image 3 As shown in Fig. 1, the shield plate and the air bag of the existing gas shield dam are usually installed on one anchor point (that is, on the same anchor line perpendicular to the flow direction of the river). In this case, if one of the several airbags is damaged and needs to be replaced or repaired, the shield and the airbag must be removed together, because the steel shield is bulky and heavy, and it is troublesome to disassemble and reinstall . [0003] For this reason, for the convenience of maintenance and dismantling of the airbag, some production units have proposed a technical scheme of installing the airbag and the shield plate on two anchor lines respectively, such as the p...
