Description

Movable double-cavity water retaining dam

Technical field

The utility model belongs to the technical field of emergency water retaining equipment, in particular to a movable double-cavity water retaining dam.

Background technique

Timely blocking rainwater in underground buildings, such as underground garages and subway entrances, is an effective measure to prevent heavy rains and heavy rains from flooding vehicles and properties in underground buildings and causing huge losses.

The Chinese invention patent application "double-cavity rubber water retaining dam bag" (application number: 201910407519.4, publication date: 2019.8.16) discloses a double-cavity rubber water retaining dam bag, including a water retaining rubber dam bag arranged on the water-incoming surface and The supporting rubber dam bag on the back water surface is filled with water or air respectively in the water-retaining rubber dam bag and the supporting rubber dam bag. Under the action of hydrostatic pressure, the supporting rubber dam bag can be tilted in the opposite direction and pressed on the back water surface, and the bottom of the water-retaining rubber dam bag and the supporting rubber dam bag are fixed on the foundation by anchors.

However, the bottom of this kind of water retaining dam bag is fixed to the foundation by anchors, which is difficult to construct and takes a long time to install. It can only be used in fixed occasions, and is not suitable for occasions that require temporary and rapid installation of water retaining facilities, such as underground projects and roads.

Summary of the invention

The purpose of the utility model is to provide a movable double-cavity water retaining dam, which is easy to construct and install, and is convenient for quick installation.

The technical solutions to achieve the purpose of the utility model are:

A movable double-cavity water retaining dam includes a water retaining dam bag 1 arranged on the front water surface and a supporting dam bag 2 arranged on the back water surface. The fixed connection also includes a floor mat 4 whose front part can be attached to the ground 5 and the rear end is sealed to the dam bag 1.

Preferably, the floor mat 4 includes a flexible backing plate 43, and the front end of the backing plate 43 is provided with a transverse bead 41.

Compared with the prior art, the utility model has the following remarkable advantages:

The construction and installation are simple: the utility model makes full use of the ground mat 4 to be attached to the ground 5, and uses the weight of the flood itself to compress the retaining dam. The higher the water level, the greater the pressure, the dam and the ground 5 are self-adaptively fixed, construction and installation are simple and easy to set up quickly. It is suitable for occasions that require temporary and rapid installation of water retaining facilities, such as underground projects and roads.

The utility model will be further described in detail below in conjunction with the drawings and specific embodiments.

Detailed ways

As shown in Figure 1, the mobile double-cavity retaining dam of the present invention includes a retaining dam bag 1 arranged on the water facing surface and a supporting dam bag 2 arranged on the back water surface. The front part of the supporting dam bag 2 is connected to The rear part of the water-retaining dam bag 1 is flexibly fixedly connected, and further includes a ground mat 4 whose front part can be attached to the ground 5 and the rear end of the water-retaining dam bag 1 is hermetically connected.

Preferably, the water retaining dam bag 1 and the supporting dam bag 2 are filled with air or water in a horizontally cylindrical shape.

The upper part of one end of the dam bag 1 is provided with a filling inlet 11 for inflation or water filling, and the upper part of the other end is provided with a discharge outlet 12 for exhausting or draining water.

The upper part of the supporting dam bag 2 is provided with a filling inlet 21 for inflation or water filling, and the upper part of the other end is provided with a discharge outlet 22 for exhausting or draining water.

When the flood hits, lay the ground mat 4 of the movable double-cavity retaining dam flat on the ground 5. Fill the retaining dam bag 1 and the supporting dam bag 2 with air respectively, and flood the ground mat 4 and the retaining dam bag 1. Block the flood; the flood anchors the floor mat 4 on the ground 5. The floor mat 4 prevents the dam bag 1 from being washed away by the water; the supporting dam bag 2 supports the dam bag 1 to prevent the dam bag 1 from rotating upward.

As the flood level rises, a water pump is used to fill the blocked flood water into the retaining dam bag 1 and the supporting dam bag 2, replacing the original air. The water retaining dam bag 1 and the supporting dam bag 2 generate greater friction with the ground due to the water pressure in the body, and the ability to resist flood impact is enhanced, and the water retaining height is increased.

The utility model makes full use of the bonding of the ground mat 4 and the ground 5, and uses the weight of the flood itself to compress the retaining dam. The higher the water level, the greater the pressure, which realizes the self-adaptive fixation of the water retaining dam of the utility model and the ground 5, and the construction and installation are simple and convenient for quick setting. It is suitable for occasions that require temporary and rapid installation of water retaining facilities, such as underground projects and roads.

As an improvement, the floor mat 4 includes a flexible backing plate 43, and the front end of the backing plate 43 is provided with a transverse bead 41.

Longitudinal strips 44 are provided on both sides of the front part of the backing plate 43.

Beads

41, 44 are arranged at the front end or even on both sides of the front of the backing plate 43. The beading bars are composed of solid materials with a specific gravity much greater than water, such as iron blocks and aluminum blocks, which can prevent the floor mat 4 from being washed by water and floating during the initial stage of water blocking. The mat 4 and the ground 5 are closely attached to each other. Therefore, the device is easier to be fixed on the ground by water pressure to realize its water-retaining function.

A plurality of drainage ditches 42 are longitudinally provided on the lower surface of the rear part of the backing plate 43.

A longitudinal drainage ditch 42 is provided on the lower surface of the back of the backing plate 43, so that the residual water on the ground or the water that has penetrated through the front or both sides of the backing plate 43 during the initial installation of the device can be drained away in time to avoid the gap between the floor mat 4 and the ground 5. There is excess water and sliding occurs, thereby further improving the anchoring effect of the floor mat 4.
