1. A shield apparatus, comprising, a first block, a second block arranged for mounting to a first top surface of the first block,  and  a third block arranged for mounting to a second top surface of the second block,  and  the first block, the second block, and the third block are each of a predetermined length and are each of a predetermined width,  and  the first block includes a first block cavity, the second block includes a second block cavity, and the third block includes a third block cavity, wherein the first block cavity, the second block cavity, and the third block cavity are each in fluid communication relative to one another when the first block, the second block, and the third block are mounted relative to one another, and  the first block includes a first floor and first top wall, with the first top wall spaced from and parallel the first floor, the first top wall includes a first rib coextensively directed along the first top wall and wherein the first block includes parallel first side walls and parallel first end walls, with the first rib extending orthogonally between the first end walls, and one of said first side walls includes a drain conduit directed therethrough in fluid communication with the first cavity, the drain conduit including a valve member arranged for effecting selective fluid flow through the drain conduit, and the first rib including a first rib top wall arranged parallel to and spaced above the first top wall, the first rib top wall including a first bore directed therethrough spaced from one of said first end walls a predetermined spacing, and a continuous torroidal "O" ring mounted in surrounding relationship relative to the first bore and secured to the first rib top wall extending above the first rib top wall. 2. An apparatus as set forth in claim 1 wherein the second block includes a second floor, the second floor including a second floor groove, and the second block further including spaced parallel second end walls and spaced second side walls, with the second floor groove orthogonally directed between the second end walls complementarily receiving the first rib therewithin, the second floor groove including a second floor groove top wall parallel to and spaced above the second floor, with the second floor groove top wall including a rigid conduit directed through the second floor groove top wall, with the rigid conduit extending below the second floor groove top wall and spaced from one of said second end walls for reception within the first bore, and the second block further including a second top wall, the second top wall spaced from and parallel the second floor, and the second top wall including a second rib directed coextensively between the second end walls and orthogonally oriented relative to the second end walls, with the second top wall including a second rib, the second rib including a second rib top wall, the second rib top wall including a second bore, the second bore spaced from one of said second end walls a further predetermined spacing and the second bore including a second "O" ring in surrounding relationship relative to the second bore secured to the second rib top wall and extending above the second rib top wall. 3. An apparatus as set forth in claim 2 wherein the third block includes a third floor and a third top wall spaced from and parallel the third floor, the third floor including a third floor groove, and the third block further including third end walls spaced apart in a parallel relationship, wherein the third groove is orthogonally oriented relative to the third end walls extending through the third end walls, and wherein the third groove includes a third groove top wall, the third groove top wall spaced above and parallel the third floor, the third groove top wall including a rigid conduit spaced from one of said third end walls the further predetermined spacing, wherein the third floor top wall rigid conduit projects below the third floor groove top wall for reception within the second bore, and the third block top wall includes a third bore, and further includes a fourth bore, the fourth bore including a fourth bore conduit projecting above the third top wall for receiving a fluid-filled conduit in securement thereto.
