Description

Technical Field

[0001] The present invention relates to the technical field of maintenance equipment, and in particular to municipal engineering machinery. Background Art

[0002] Many cities often experience severe flooding during heavy rainstorms. Rainwater backflow may occur at the entrances and exits of underground garages, subways, and underground pedestrian passages, causing huge economic losses.

[0003] At present, sandbags are often stacked into retaining walls to prevent rainwater from flowing back into the interior of underground facilities. This can greatly slow down the backflow of rainwater from the entrances and exits of underground facilities. However, stacking sandbags into retaining walls requires a lot of manpower and takes a long time to build. Therefore, it is necessary to develop a water retaining device that can be used at the entrances and exits of underground facilities to facilitate staff to quickly build a water retaining barrier.

When in use, the machine can be carried to the entrance or exit of an underground facility, where the water-retaining airbag is inflated. The left-end waterproof pad and the right-end waterproof pad are then placed against and fixed to a wall or other facility to form a water barrier.

[0039] Furthermore, the left and right waterproof pads 20 and 30 are detachably connected to the two ends of the water-retaining airbag 10. The water-retaining airbag 10 passes through multiple support legs 40, and the water-retaining airbag 10 is connected to the support legs 40, which can prevent the water-retaining airbag 10 from rolling due to impact force.

[0040] Furthermore, the wall of the water-retaining airbag body 10 has an inverted portion 11 and forms a storage cavity 12 , which is communicated with the outside and is used to store accumulated water, thereby increasing the weight and changing the center of gravity of the water-retaining airbag body 10 .

[0041] Furthermore, the storage chamber 12 is located on the water-facing surface of the water-retaining airbag body 10 .

[0042] In this embodiment, the water retaining airbag 10 and the supporting frame 40 are respectively provided with a first connecting ring 13 and a second connecting ring 41 .

[0043] The first connecting ring 13 has a connecting rope 14, one end of the connecting rope 14 is fixedly connected to the first connecting ring 13, and the other end of the connecting rope 14 is fixedly connected to the second connecting ring 41. The water-retaining airbag body 10 has good stability and is not easily separated from the supporting leg 40, which is convenient for transportation.
