Problems solved by technology

There are issues with the current berm options.
The liner cannot be directly attached and requires staking.
The earthen berms also tend to collapse into ruts under repeated vehicle traffic.
While railroad ties can be moved from site to site for reuse, they are hard to decontaminate since they are covered in creosote and are absorbent to the chemicals on si

Embodiment Construction

[0021]Embodiments of the present invention provide drive-over berms for use with protective liners that are structured and arranged to allow vehicular traffic over the berms. In one embodiment, the berms comprise a base with an upwardly extending rigid body that is shaped to allow vehicle tires to travel up and over the berm. In another embodiment, the berms comprise a base with an upwardly extending collapsible resilient body that compresses or deforms when the weight of a vehicle tire travels over the berm, and then returns to its original shape after the tire passes. As used herein, the terms “drive-over berm” and “structured and arranged to allow vehicular traffic over the berm” refer to either of these embodiments, or a combination thereof.

[0022]FIG. 1 is a plan view of a liner and berm assembly 10 in accordance with an embodiment of the present invention. The liner and berm assembly 10 includes a liner 12 comprising a liquid-impermeable sheet of material. The liner 12 may be m...

Abstract

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.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Patent Application Ser. No. 61 / 555,523 filed Nov. 4, 2011, and U.S. Provisional Patent Application Ser. No. 61 / 581,884 filed Dec. 30, 2011, both of which are incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates to liners that protect the environment from spills and leaks at sites such as oil and gas well drilling sites, and more particularly relates to berms for use with such liners.BACKGROUND INFORMATION[0003]In conventional gas and oil drilling, large quantities of drilling mud, fracturing chemicals and flowback water are on site. Many operating companies compact the pad site and place a liner over the entire surface. The liner is pulled over earthen berms, railroad ties, corrugated pipe or foam blocks to form containment sidewalls or berms around the perimeter. The liner and berms then contain the leaks and spills so that on-site vacuum trucks...
