Protective system
First Claim
1. A protective system for preventing deleterious gases from entering a building structure from a surrounding ground environment, comprising:
- (a) enclosure means mounted over a sump pit enclosing a sump pump and forming a substantially air tight enclosure, said enclosure means including (1) a first member fixedly secured to a concrete floor slab and mounted at least partially around a periphery of said sump pit, and, (2) a second member releasably secured to said first member for providing a temporary opening when said second member is removed from said first member, through which said sump pump may be removed from said sump pit without removal of said first member from said concrete floor slab;
(b) at least one conduit fitting defining a stub pipe fixedly secured to an outer surface of said second member and in axial alignment with an opening formed through a wall of said second member defining a stub through passage;
(c) means for removal of air from within said air tight enclosure and discharge external to said building structure;
(d) means for discharging liquid from said air tight enclosure to an external environment of said building structure, said means for discharging liquid including a liquid discharge pipe extending from said sump pit at least through said stub pipe through passage in a co-axial manner; and
,(e) means for securing said stub pipe to said liquid discharge pipe in a substantially air tight manner.

Abstract
A protective system (10) is provided for preventing deleterious gases from entering the internal atmosphere (34) of a building structure (12) derived from surrounding ground environments (14 and 18). An enclosure (24) is mounted above a sump (26) containing a sump pump (30) for discharging liquid (32) to an external environment (22) when taken with respect to building structure (12). Mounted adjacent to the enclosure (24) is a fan mechanism (52) for drawing a partial vacuum in an enclosure chamber (28 and 28'"'"'). The fan mechanism (52) is in fluid communication with a gas discharge pipe (58) for passing or displacing contaminated gas into the external atmosphere (22). Radon contaminated gas passes through perforated drainage pipes (48) into sump (26) and due to the negative pressure gradient created by fan mechanism (52), radon contaminated gas is displaced through gas discharge pipe (58) to the external atmosphere (22). The enclosure (24) and couplings thereto are formed in substantially airtight relation and thus, the contaminated gas being drawn from enclosure chambers (28 and 28'"'"') is not directed into the building structure internal atmosphere (34), but displaced directly to the external atmosphere (22).

13. A protective system for preventing deleterious gases from entering a building structure from a surrounding ground environment, comprising:
-
(a) enclosure means mounted over a sump pit enclosing a sump pump and forming a substantially air tight enclosure, said enclosure means including (1) a first member fixedly secured to a concrete floor slab and mounted at lest partially around a periphery of said sump pit, and, (2) a second member releasably secured to said first member for providing a temporary opening when said second member is removed from said first member, through which said sump pump may be removed from said sump pit without removal of said first member from said concrete floor slab; (b) at least one conduit fitting defining a stub pipe fixedly secured to an outer surface of said second member and in axial alignment with an opening formed through a wall of said second member defining a stub through passage; (c) means for removal of air from within said air tight enclosure and discharge external to said building structure; (d) means for discharging liquid from said air tight enclosure to an external environment of said building structure, said means for discharging liquid including (1) a liquid discharge pipe extending from said sump pit at least through said stub pipe through passage in a co-axial manner, (2) at least a lower liquid discharge pipe extending from within said sump pit and through a wall of said second member defining an end section of said lower liquid discharge pipe, and (3) at least an upper liquid discharge pipe in coaxial alignment with said lower liquid discharge pipe and flexibly secured in substantially air-tight coupling to said lower liquid discharge pipe. - View Dependent Claims (14, 15)
