Abstract
Apparatus suitable for venting and dispensing gas from an area of ground. The apparatus comprising a passage arrangement locatable in the ground extending generally horizontally and formed from a plurality of self-supporting open units. One or more columns extends downwardly from the passage, the columns being formed of a core material having an open permeable structure. The or each column has a fluid permeable exterior, and is in communication with the passage.
Claims19
Apparatus for dispersing a gas from an area of ground, the apparatus comprising a passage arrangement locatable in the ground extending generally horizontally to at least partially surround the area of ground, the passage arrangement having a substantially impermeable exterior, one or more column arrangenments through which fluid can pass, the or each column arrangement being locatable in the ground extending downwardly from the passage arrangement and in communication therewith, with at least part of the or each column arrangement having a fluid permeable exterior to receive gas from the area of ground, means for creating a below ambient pressure in the passage arrangement such that gas is drawn thereinto from the column arrangement or arrangements, the below ambient pressure creating means comprising means for creating a flow of air through the passage arrangement, an inlet, and an outlet extendible from the passage arrangement to atmosphere.
A method of preparing an area of ground to facilitate dispersal of gas from the ground comprising:
- installing a passage arrangement in the ground and extending generally horizontally to at least partially surround the area of ground, the passage arrangement having a substantially impermeable exterior, an inlet, and an outlet extending to atmosphere,
- providing one or more column arrangements through which fluid can pass, the or each column arrangement being located in the ground and extending downwardly from the passage arrangement and in communication therewith, with at least part of the or each column arrangement having a fluid permeable exterior to receive gas from the area of ground.
- whereby upon creating a flow of air through the passage arrangement and thereby creating a below ambient pressure in the passage arrangement, gas is drawn threinto from the column arrangement or arrangements.
A method of substantially preventing lateral gas migration from an area of ground, the method comprising:
- installing a passage arrangement in the ground and extending generally horizontally to at least partially surround the area of ground, the passage arrangement having a substantially impermeable exterior, an inlet, and an outlet extending to atmosphere.
- providing one or more column arrangements through which fluid can pass, the or each column arrangement being located in the ground and extending downwardly from the passage arrangement and in communication therewith, with at least part of the or each column arrangement having a fluid permeable exterior to receive gas from the area of ground,
- creating a flow of air through the passage arrangement and thereby creating a below ambient pressure in the passage arrangement so that gas is drawn thereinto from the column arrangement or arrangements.
