Anti-alteration wellhead vault

a wellhead vault and anti-alteration technology, applied in the field of wellhead protection systems, can solve the problems of only being moved, too heavy for human lifting, and the weight of the vault is so high that it cannot be removed, so as to improve the run-off of rain and snow, and less weather-related degradation of the enclosure

Benefits of technology

The solution effectively prevents malicious access and accidental damage to wellheads, enhancing the security and integrity of water supplies while being cost-effective, with the vault's weight and construction making it difficult to move or penetrate without heavy equipment, thus safeguarding against various threats.

Problems solved by technology

The vaults too heavy to be removed by human lifting.
The vault is constructed from a material that would require a noisy and conspicuous effort to penetrate.
Furthermore, the well vault is of such a weight that it can only be moved using heavy-duty construction equipment, use of which would also necessarily be noisy and conspicuous.

second embodiment

[0079]FIG. 5 is a front elevation view of the present invention, having a square foot print. This anti-alteration wellhead vault system, designated generally by the 10a, includes precast concrete bell-shaped vault 11a. The vault 11a has lifting elements 12a mounted on the side of the vault 11a. The lifting element 12a is in the form of a loop of a metal bar the ends of which are embedded in the concrete of the vault 11a. The lifting element 12a allows the vault 11a to be placed and lifted using heavy construction equipment. The vault 11a also includes air vents 13a and 14a (shown below).

[0080]FIG. 6 is a plan view of the embodiment shown in FIG. 5. The vault system 10a includes the vault 11a. The vault 11a includes the lifting element 12a, and the air vents 13a and 14a. The vault 11a might be sitting on a concrete pad which is positioned in the ground, around a wellhead.

third embodiment

[0083]FIG. 9 is the well vault 11b present invention in which a step-like ledge 41 is provided around the outside of the well vault 11b. This ledge provides convenient support for a person to maintain the upper portion of the vault 11b, or to assist in connecting the lifting elements 12b to the heavy lifting equipment for positioning the vault 11b. This anti-alteration wellhead vault system, designated generally by the 10b, includes precast concrete bell-shaped vault 11b. The vault 11b has lifting elements 12b mounted on the top of the vault 11b. The lifting element 12b is in the form of loops of a metal bars the ends of which are embedded in the concrete of the vault 11b. The lifting element 12b allows the vault 11b to be placed and lifted using heavy construction equipment. The vault 11b also includes air vents 13b and 14b. The vault 11b be is sitting on a flat concrete pad 17 that is buried in the ground 18.

[0084]FIG. 10 is a plan view of the embodiment shown in FIG. 9. This thir...

Abstract

A wellhead vault for preventing alteration of the wellhead of a water supply. The vault is a heavy bell-shaped structure, formed of concrete, and having a downwardly facing concavity, and the vault placed over, with the concavity around the wellhead. The vaults too heavy to be removed by human lifting. Lifting elements are provided to allow the vault to be installed and removed by heavy construction equipment. The vault has a vent that communicates between the concavity and the outside, allowing air, but not liquid, liquid or solid contaminants, or animals, to pass through.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]NA.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0002]This invention has been created without the sponsorship or funding of any federally sponsored research or development program.FIELD OF THE INVENTION[0003]This invention involves a system for protecting wellheads that are part of water supplies.BACKGROUND OF THE INVENTION[0004]40 years ago, there seemed to be no terrorist threat, but in today's world it seems we have people and groups of people that will stop at nothing to hurt, maim and kill others, even children. This invention involves a wellhead that is protected by an anti-alteration well vault. The vault enhances the security of our precious water supply and protects the safety of water supply consumers. This protected wellhead will go a long way toward protecting municipal and private well water supplies and could be used also to protect oil or gas wells, whether active or abandoned, from alteration, including n...
