A temporary water barrier for residential and commercial doors. The temporary water barrier is an inflatable bladder that is configured to be installed in a doorway and inflated to create a barrier to water within the jam of the door or opening beneath the door. The elongate bladder has sealed ends, an inflation valve to communicate an inflation fluid to an interior of the bladder. A resilient seal may be provided along one or more of a top surface and a bottom surface of the bladder. A notch may be defined in the bladder with the notch dimensioned to fit around a hinge supporting the door in the doorway.

A method for protecting a building against flooding by use of a membrane connected along a first side edge to a float, and comprises the steps of arranging the membrane in a packed configuration at a first distance from the building, and fixing the membrane to the ground at a start location along a second side edge, allowing water to unpack the membrane and move the float toward the building to arrange a first portion of the membrane with a lower surface against ground in an area between the start location and the building, allowing water to raise the float a second distance along an outer surface of the building while further unpacking the membrane to arrange a second portion of the membrane with the lower surface against the building. The first portion forms a retention portion which is retained on the ground by water on an opposite upper surface.

A modular dike or barrier system includes interconnectable side and corner members having front and rear walls with integrally formed support ribs. Upper, base and side end walls connect and are integral with the front and rear walls. Each of the front and rear walls extends at an acute angle relative to the base wall that is configured to rest against a substratum. The inward acute angle allows for containing and redirecting a surge flow inwardly within an area contained by the barrier system in a direction away from the members. The members are generally plate-like and are configured to allow for horizontal stacking on the substratum. Members can include a selectively collapsible support assembly configured to be retained at central bodies of the respective members and to limit interference during stacking and transport of the members.

A system of structural interlocking panels for forming disaster-resistant buildings, comprising: a hollow, internally-braced, vacuum-insulated panel shell having at least two interlocking sides, the first side having a convex-inward single-curvature, the second side having a straight surface, the third side having a straight surface with at least one integral tongue with at least one head extending vertically-upward for receiving a complementary groove of a first side of an adjacent panel. Panels are thus vertically slide-locked along panel sides and faces, thereby triggering automatic snap joints that prevent backward movement of the panel. The system can assemble spheres, cylinders, toroids, tetrahedrons, flat shapes, and irregular shapes.

The present invention discloses a flood protection device. The device comprises at least one base, at least one telescoping pole installed in each corner of base, a heavy duty flexible material bag to cover at least one item placed on base and at least one locking unit comprising locking seal and button lock to seal bag. To cover the item using the device, first the item is placed on base. Then the poles are installed on the base to support the bag. After covering the item using bag, the locking seal and button lock are closed to seal the bag. The height of poles are adjustable to create sufficient space for item to be placed. The bag protects the item placed inside the device from flood and avoids any damage of it during flood and storm.

Flood protection apparatus for temporarily blocking a building opening (30) to guard against the ingress of flood water. The apparatus comprises a collapsible bag (10) formed from a watertight conformable material and has a filling means (20) for admitting a flowable filling medium to the bag (10) to expand the bag (10) from a collapsed state. When the bag (10) is disposed in the building opening (30) and filled, the bag (10) conforms to and seals against a periphery of the building opening (30) under the pressure of the filling medium to define a sealing region (A) across the building opening (30). A pair of buttress regions (B) are disposed on front and rear sides of the sealing region (A). The weight of the filling medium in the buttress regions (B) acts to prevent displacement of the bag (10) from the building opening (30).

A flood prevention device includes a gate device constituting a passage between a flood prevention area and an outside area, and a portable flood prevention material that separates the flood prevention area and the outside area with the gate device. The gate device has a side wall corresponding to one end of the portable flood prevention material.

The invention relates to a perforating device for thermoplastic plates, which relates to the technical field of a plate processing device. The device comprises an electromagnetic chuck, one side of the electromagnetic chuck is connected with the motion part, the other side of the electromagnetic chuck is connected with a mounting plate and a spike. When the electromagnetic chuck is powered on, the spike is attracted below the mounting plate by the electromagnetic force. A clamping part is arranged below the mounting plate, the thermoplastic plate is fixed by the clamping part, and a heating system is also provided to heat the thermoplastic plate. As the electromagnetic chuck is powered on or off, the spike can be attracted in or separated from the mounting plate, respectively. Therefore, the perforating device can make a new plate be pierced during the cooling and curing process of the perforated plate.

Scale habitable units are disclosed for use in marine environments, such as the open sea, which are inexpensive to assemble and maintain, while providing habitable space.

A ground sealing arrangement for a portable flood barrier to be positioned on the ground includes a vertical wall and a main sealing layer forming a main body. The main sealing layer is impermeable to water. The ground sealing arrangement further includes a bottom sealing layer arranged on a ground-facing underside of the main sealing layer. The bottom sealing layer is attached to the main sealing layer at a distance from a peripheral edge of the main sealing layer that is most distal from the first edge of the ground sealing arrangement such that the bottom sealing layer has a free end extending from the point where the bottom sealing layer attaches to the main sealing layer towards the peripheral edge of the main sealing layer, and comprises a highly flexible and/or glutinous material which is stretchable and sticks to the ground when the material is soaked with water.
