Water Containment System

Abstract

A temporary dam system for containing a body of water is provided. The temporary dam system is constructed with a number of dam sections. Each dam section has three or more supports and a back brace for supporting a resistant membrane backed by a plate. The supports comprise an end support, a middle support, and a top support in an A-frame structure. A membrane backing plate is attached to the front of the assembled support structure. The overall containment dam system is constructed by connecting dam sections together to form a continuous wall of rigid plates facing a body of water. A flexible liquid-impervious membrane is then placed over the rigid plates to contain the water.

AI Technical Summary

Benefits of technology

[0028]An embodiment of the present invention is a supporting structure, a membrane support plate, and a water membrane which contacts the water and contains it. The supporting structure is light weight in design, and alternates in three primary parts: an end support frame and a middle supporting frame. A top supporting frame is also included in many embodiments, but not in all. The design features simplified field erection, light weight transportation, and an efficient design for following a field directed path without the use of surveyors.

[0029]An important embodiment of the present invention includes additional structures which allow convenient methods to turn the support structure and membrane support plate in a way that allows the water containment system to follow a curved path rather than o...

Problems solved by technology

Conventionally, sandbags and earthen berms or dams are used in these situations to form dikes to contain the water, however, these methods are time consuming and very labor intensive.

U.S. Pat. No. 6,676,333 by Wiseman et al is an attempt to provide a temporary type of structure, but it lacks practicality due to the frequent support structures, and the membrane used to contain the water is poorly supported.

As a practical matter, it is not very portable or mobile.

U.S. Pat. No. 6,132,140 by Kullberg is another attempt to provide a temporary type of structure, but it also lacks practicality and economy due to the excessive weight/design of the membrane support face, which is very heavy.

Also, the design lacks consideration to ensure that a multi-curve path can be followed.

The design is very heavy, complicated, and the pipe/rod system requires field bending.

Field installation is labor intensive; requiring training and special tools.

The design is complicated and it is questionable that the design would be stable under actual hydrostatic pressure conditions.

The design is very complicated, heavy, and needs soil for weight to stabilize the base.

The system is difficult and unappealing to utilize in the event of a natural disaster where it needs to be installed by a flood.

The design is overly complicated for a temporary dam system requiring an excessive amount of work to fill the various structures with water in place.

Sandbags are a method to bui...
