Abstract
A slab with two or more adjacent sub-slabs with a space therebetween and a liquid stop spanning the space, a portion of the liquid stop embedded in each of the sub-slabs. In one aspect, when joint material is present in the space, the liquid stop is, preferably, disposed beneath the joint material. A liquid containment system for a treatment facility with liquid containing vessel(s) and slab(s) which includes liquid stop apparatus for each slab/slab interface and liquid stop apparatus for each slab/vessel interface.
Claims6
A liquid containment system for a treatment facility, the treatment facility including a plurality of spaced-apart liquid containing vessels and a plurality of concrete slabs one adjacent the other with spaces therebetween, vessels adjacent slabs at an interface thereof, the system comprising
- slab liquid stop member means between each of every two adjacent slab members;
- the liquid stop member means comprising a first slab stop portion, a second slab stop portion, and a third slab stop portion;
- the first slab stop portion embedded in one of two adjacent slabs, the second slab stop portion embedded in the other of the two adjacent slabs, and the third slab stop portion extending along a length of a space between the slabs,
- an expansion joint member disposed between the slabs above the third slab stop portion,
- vessel liquid stop member means between each vessel and every slab adjacent a vessel;
- the vessel liquid stop member means comprising a first vessel stop portion having a first end secured to an exterior wall of the vessel, and a second end secured to an anchor embedded in a slab adjacent the vessel to seal the interface between the vessel and the slab.
A liquid containment system for a treatment facility, the treatment facility including a plurality of spaced-apart liquid containing vessels and a plurality of concrete slabs one adjacent the other with spaces therebetween, vessels adjacent slabs at an interface thereof, the system comprising
- slab liquid stop member means between each of every two adjacent slab members;
- the liquid stop member means comprising a first slab stop portion, a second slab stop portion, and a third slab stop portion;
- the first slab stop portion embedded in one of two adjacent slabs, the second slab stop portion embedded in the other of the two adjacent slabs, and the third slab stop portion extending along a length of a space between the slabs,
- an expansion joint member disposed between the slabs above the third slab stop portion,
- vessel liquid stop member means between each vessel and every slab adjacent a vessel;
- the vessel liquid stop member means comprising a first vessel stop portion having a first top end secured to an exterior wall of the vessel and a second bottom end beneath the first top end spaced apart from the exterior wall of the vessel, and
- the slab liquid stop member means including a fourth slab stop portion having a first end secured to the anchor embedded in the slab and a second end overlapped by the second end of the first vessel stop portion.
A liquid containment system for a slab interface between a first slab and a second slab, the first slab spaced apart from the second slab by a space, and for a curb interface between an edge of both slabs and a curb adjacent the edges of both slabs, the system comprising
- a liquid stop means for preventing liquid flow through the space between the slabs,
- the liquid stop means comprising a strip which extends along and beneath the slabs and the space between the slabs, and
- the liquid stop means further comprising an upwardly extending portion of the strip extending into the curb adjacent the edges of both slabs.
