Roller shutter type three-station waterproof weir

Abstract

The invention discloses a roller shutter type three-station waterproof weir, and relates to the waterproof field of underground construction. The waterproof weir comprises a first cylinder, a second cylinder, a steel wire rope, a first flash board, a second flash board, a speed reducing motor connected with the first cylinder, a first sliding chute, a second sliding chute, two threshold bases and a floating rotating shaft, wherein one end of the steel wire rope is fixedly connected with the first cylinder; the steel wire rope is arranged along the first sliding chute; the steel wire rope penetrates through the threshold base, bypasses the floating rotating shaft, penetrates through the other threshold base, and is arranged along the second sliding chute; the other end of the steel wire rope is wound on the second cylinder; and the first flash board and the second flash board are fixed on the steel wire rope. The roller shutter type three-station waterproof weir can prevent rain from flowing backward without influencing people and vehicles to go in and out, and is high in degree of automation, flexible in water retention height, synchronously waterproof in real time, simple in structure, high in durability, convenient to construct, low in cost and convenient to maintain; and the labor cost is reduced.

Description

technical field [0001] The invention relates to the field of waterproofing of underground buildings, in particular to a rolling shutter type three-station waterproof weir. Background technique [0002] At present, the measures for waterproofing and backfilling of underground buildings generally include: pre-designing and marking the water level, setting steps or slopes of a certain height at the entrance and exit, or setting up an anti-flooding tank at the entrance and exit, and equipped with an anti-flooding plate matching the anti-flooding tank. When the water level When the pre-designed marked water level is exceeded, the anti-flooding plate will be inserted into the anti-flooding groove by a special person to form an anti-flooding baffle. [0003] The above measures have the following disadvantages: [0004] (1) After setting steps or slopes, the ground elevation of the underground building itself, the elevation of surrounding buildings and roads must be recalculated, w...

[0005] (2) The anti-flooding baffle needs to be supervised by a special person. When there are many entrances, a large amount of manpower is required to be distributed to each entrance. The labor cost is high, and the water retaining height is not flexible, so it is difficult to play the role of waterproofing in a timely and synchronous manner.
