CONTAINMENT DIKE

摘要

Flexible containment tubes form sections of a dike for fluid containment. For example, multiple vinyl-coated polyester tubes with a 19-inch diameter may be filled with water and stacked on top of each other to create a temporary diversion dike. Multiple sections of dike may be abutted together to form longer sections of dike. A vapor barrier or plastic membrane may wrap over dike sections and/or weaved through the flexible containment tubes as they are placed prior to filling. Configurations of the vapor barrier and associated anchoring mechanisms improve the utility of dike sections by reducing hydrostatic pressure of contained fluid on the dike, harnessing the weight of fluid columns, and mitigating seepage through the dike sections.

主权项

1. An apparatus for containing a fluid within a containment area, the apparatus comprising:
a plurality of containment tubes stacked on a ground surface in a pyramid formation, each flexible containment tube comprising a flexible body and configured to receive a filling fluid; a vapor barrier comprising,
a first portion of the vapor barrier extending from a front base of the pyramid formation into the containment area along the ground surface,a second portion of the vapor barrier extending down a front face of the pyramid formation to the ground surface at the front base of the pyramid formation, the front face of the pyramid formation forming a portion of the containment area, anda third portion of the vapor barrier weaving between one or more of the plurality of containment tubes along a rear face of the pyramid formation into an interior of the pyramid formation while extending down the rear face of the pyramid formation to the ground surface at a rear base of the pyramid formation.
