The invention relates to flood protection comprising a plurality of fillable sacks made of flexible fabric material, with mutually adjacent coupling sides of adjacent sacks being connected to one another in a coupling region and with at least one stiffening structure being associated with each coupling region and extending from the base region of the sacks up to their upper marginal region.

A modular dike assembly includes strut and corner members that may be interconnected to form a barrier or dike wall surrounding a primary container. The strut members are stackable for convenience in transporting the system and an alignment web is provided for defining the interior perimeter of the closed barrier or dike wall and to secure assembled members together.

A bag made from a length of material (10) divided into a series of three or more substantially equal sized sections (12, 14, 16, 18, 20). Every other section is filled with sand (14, 18), or other particulate material and there is an unfilled section (12, 20) at each end.

A modular dike assembly includes strut and corner members that may be interconnected to form a barrier or dike wall surrounding a primary container.

A levee and barrier module for fluid control and containment is provided including an outer module shell and a module-to-module connection system to attach adjacent outer shells. The outer module shell, being in the general shape of a prism or prism with curvilinear section, is formed by opposing side walls and two opposing end walls, and is configured to enclose or support filler material. The two opposing end walls are configured with end apertures. The outer module shell defines a top aperture and a bottom aperture. When modules are placed end to end in a levee structure the end apertures allow filler material communication horizontally between adjacent modules. The bottom aperture allows filler material communication with the earth below the module. The top aperture allows filler material to be added to the module, as well as visual observation of, and maintenance of, the amount of contained filler material.

Berms for use with protective liners are disclosed. The berms may be configured to allow vehicular traffic to pass over the berms without causing damage. Such drive-over berms may be rigid and shaped to allow vehicle tires to pass over them, or may be resilient and collapsible such that they collapse when subjected to the weight of a vehicle tire, and then spring back to shape after the vehicle passes. Also disclosed are berms that may be stacked for storage and transportation purposes, and berms that include connectors for connecting multiple sections of the berms end-to-end.

A portable, inflatable flood wall is characterized by a sheet of synthetic plastic material which is folded back on itself to define a chamber between bottom, rear and front portions of the sheet and within which at least one inflatable bladder is secured. When the bladder is inflated, the rear portion of the sheet is erected to a vertical position which prevents water from passing beyond the sheet. The front portion preferably contains a plurality of openings to allow water to enter the chamber. The weight of the water on the bottom portion of the sheet serves to hold the wall in place. A plurality of such walls may be connected in end-to-end relation to construct a wall of a desired length.

System for containing liquid introduced onto a reusable load-supporting surface includes a plurality of interconnectable berm members configured to releasably sealingly engage the load-supporting surface to prevent leakage of liquid from the load-supporting surface around its perimeter.

A hazardous spill ground containment system having a plurality portable metal frame sections. The frame sections are used to create an angular shaped containment frame received over various types of ground surfaces. The frame sections can be made to different lengths and heights and are used for holding in place a heavy duty liner on top of the ground surface. The liner is adapted for receiving various types of equipment, tanks and containers holding toxic chemicals and the like hazardous materials. The metal frame sections include an elongated, metal, A-shaped lower frame member and an elongated, metal, Z-shaped upper frame member for receiving and holding a side of the liner securely in place.

The invention discloses a construction method for filling a mortar combined stone dam, which combines a mortar grouting and filling method and a rock-fill dam filling construction process, and solves the problems that a stone masonry structure is inconvenient to use mechanical construction and has low working efficiency, and a rock-fill dam has higher requirement on grain diameters of filling stones, lower material source utilization rate, high manufacturing cost and the like. The construction method comprises the following steps: filling stones in a dam shell till reaching the thickness requirement of a filling layer, flattening the stones, and then carrying out mortar sand removal operation on the top surface of the filling layer, namely directly filling previously prepared cement mortar or cement mixed mortar doped with admixture fly ash into the screened sand quantitatively supplied by a mortar conveying device in gaps of the filled stones through the mortar conveying device to form the mortar combined stone dam similar to the mortar masonry stone dam. The process flow is simple, the application range is wide, the maximum block diameter control and grade matching requirements are not needed, the stone source is abundant, the thickness of the filling layer is large, the roller compaction is not needed, the construction speed is high, the working efficiency is high, the construction cost is reduced, and the formed dam mortar masonry is compact and has good quality.

A portable, water-filled barrier emulates a sandbag dike or wall without requiring sand or intensive labor to install. The barrier is made of a light, flexible material that can include nanofiber. Some embodiments are formed from a plurality of interlocked water-filled cells, with a forward-facing water barrier sheet. Other embodiments are unitary shells that are internally divided into cells, with internal openings that permit water to flow between cells. Automatic valves can seal the filled cells, so that a punctured cell will not cause cells below and behind to deflate. A row or rows of cells can project below the base into a stabilizing trench. Cells can include internal or external rods or plates that support the horizontal structure. Embodiments can be initially filled with air, positioned, and then filled with water while the air escapes through a pressure valve. Barrier end structures can enable interlocking of adjacent units.

A flood barrier comprises hollow self-filling units (10, 12, 14, 16) placed end-to-end and connected at their ends by downwardly tapered bilobal (46) keys inserted into sockets (26, 28) at the ends of the units, wherein the keys incorporate concrete or other ballast for negative buoyancy.

A modular dike or barrier assembly includes straight and curved members that may be interconnected to form a barrier or dike wall surrounding a primary container. The members are hollow and include opposed side walls having integrally formed reinforcing ribs. The side walls extend at an acute angle relative to the base of the barrier to contain and redirect a surge flow directed toward the dike or barrier assembly. The interior surfaces of the side walls are closely spaced at locations spaced from the ribs and tend to abut for added wall reinforcement upon application of wall deflecting loads.
