Description

Technology Field

[0001] The present invention relates to a sliding flood defense water barrier, and more specifically, to a sliding flood defense water barrier that functions as part of a bridge deck during normal times without obstructing vehicle traffic, while effectively preventing flood damage by deploying a plurality of water barrier gates in a sliding manner to form a water barrier wall when activated, such as during a flood. Background Technology

[0003] With torrential rains caused by recent climate change frequently resulting in river flood levels rising above the height of existing embankments or bridges, there is an urgent need for measures to prevent urban flooding.

[0004] While embankments can be reinforced by purchasing land, it is virtually impossible to completely demolish bridges in densely populated urban areas with roads and buildings and rebuild them at a higher height, resulting in enormous costs.

[0005] To solve this problem, there is a method of installing a "rising and falling type overflow prevention wall" (hereinafter referred to as the prior art) of Patent Registration No. 10-2548870, which was previously registered by the applicant. However, the prior art has a structure in which the water-blocking wall (100) is normally stored in an underground storage space (170) and raised when necessary.

[0006] Generally, a bridge (600) installed in a stream or river is supported by a pier (610) and an abutment (620) as shown in FIG. 1(b), and a connecting slab (640) formed integrally with the bridge deck is provided at the bridge end connected to the road.

[0007] The structure of such a general bridge (600) requires deep excavation work to secure space for a watertight wall to be housed underground, and since the bridge's connecting slab (640) is directly related to the structural safety of the bridge and cannot be arbitrarily dug out or damaged, the prior art had a fundamental limitation that made it difficult to apply to such a bridge (600).

[0008] As another alternative, a sliding type sluice gate can be considered, but since this requires moving a sluice gate as wide as the width of the bridge all at once, a large area of ​​land equal in length to the sluice gate must be secured on the side of the bridge, and it is difficult to apply to wide bridges reaching tens of meters, and there is a problem that the elongated sluice gate becomes vulnerable to water pressure.

[0009] In addition, the running rails, which were constantly exposed to the road surface, caused operational malfunctions due to foreign matter jamming and resulted in inconvenience for vehicle traffic.

[0010] Therefore, there is an urgent need to develop a device that functions as part of the bridge deck under normal conditions without obstructing vehicle traffic, while effectively preventing flood damage by forming a watertight barrier when activated, such as during a flood.

[0122] And, the transfer means (500) may further include a driven sprocket (532) positioned in a straight line with the driving sprocket (522).

[0123] Additionally, the conveying means (500) may further include a drive transmission chain (540) that interconnects the drive sprocket (522) and the driven sprocket (532).

[0124] In addition, the transfer means (500) may further include an extraction pinion (530) that is positioned coaxially with the driven sprocket (532) and meshes with the rack gear (320).

[0126] As described above, it can be seen that the basic technical concept of the present invention is to provide a sliding flood defense water barrier that functions as part of the bridge deck under normal conditions without hindering vehicle traffic, while effectively preventing flood damage by deploying multiple water barrier gates in a sliding manner to form a water barrier wall when activated, such as during a flood.

[0127] Furthermore, within the scope of the basic technical concept of the present invention, it is obvious that many other variations and applications are also possible for those skilled in the art, such as installing the sliding flood defense water barrier according to the present invention in the middle of an embankment as shown in FIG. 5.

Claims

Claim 1 A sliding flood prevention device characterized by comprising: a lower guide frame embedded in the surface to be installed; a lower guide rail on one side of the lower guide frame to guide the movement of the lower end of the flood barrier; an upper guide frame positioned on the upper side of the lower guide frame to cover the lower guide rail in normal operation; an upper guide rail on one side of the upper guide frame to guide the movement of the upper end of the flood barrier; and a lifting means positioned between the lower guide frame and the upper guide frame to raise the upper guide frame away from the lower guide frame during operation. Claim 2 A sliding flood defense water barrier according to claim 1, further comprising a storage frame having a storage space inside, a lower ejection rail arranged in a first direction on the lower side of the storage frame, a movable block movable along the lower ejection rail along the first direction, and a plurality of mounting grooves formed by being recessed on the upper surface of each of the movable blocks so as to be seated on the lower end of a water barrier gate, wherein the water barrier gate is transported to the outside of the storage frame along a second direction perpendicular to the first direction to form a water barrier wall. Claim 3 A sliding flood defense water barrier according to claim 2, further comprising a transfer means provided on one side of the storage frame for transferring the water barrier gate, which has been pushed along the first direction by the loading means, toward the storage column side facing the storage frame along a second direction perpendicular to the first direction. Claim 4 In claim 1, the lifting means comprises: a first lower folding bar having a lower end rotatably coupled to the lower guide frame; a second lower folding bar having a lower end that functions as a free end movable along the bottom surface of the lower guide frame with respect to the lower end of the first lower folding bar, which functions as a rotatably fixed fixed end and is rotatably cross-coupled to the first lower folding bar and a first intermediate hinge, and which functions as a rotatably fixed fixed end; a pair of upper folding bars each having a lower end rotatably coupled to the upper end of the first lower folding bar and the second lower folding bar, which are rotatably cross-coupled to the second intermediate hinge, and which each have an upper end that folds and rotates to push up the upper guide frame when operated; and one of the pair of upper folding bars and two ends each rotatably coupled to the bottom surface of the lower guide frame and are operated to be extendable and retractable when operated, wherein normally the upper guide frame is folded and stored so as to be in contact with the lower guide frame, and when operated, receives a driving force and the pair of upper folding bars and the first lower A sliding flood defense water barrier device characterized by further including an electric cylinder that folds and rotates the folding bar and the second lower folding bar to separate the upper guide frame from the lower guide frame by a height at which the water barrier gate can move.
