Abstract
A conduit for dispersing or gathering liquids in the earth has an arch shape cross section and alternating peak and valley corrugations along its length, with cantilever legs extending from one end to interact with the mating portion of a like conduit. The legs, along with a shiplap joint having flange discontinuities for manufacturability, provide a superior rigid joint when the conduits are mated and buried beneath the earth and subjected to vertical loads.
Claims18
A conduit for burial in the earth to disperse or gather liquids therein, the conduit having a wall shaped to form an arch shape cross section, an open base, and alternating peak corrugations and valley corrugations along the conduit length, with the top of the device during use being the top of the arch;
- the conduit having an overlapped end and an opposing overlapping end, the ends adapted to mate in shiplap fashion with the corresponding overlapping and overlapped ends of like devices;
- characterized by
- a cantilevered leg attached to and extending from one end, running parallel to the length of the conduit;
- the leg forming with the adjacent portions of said one end a female pocket-like space, to receive therein a portion of the end of a mating conduit, wherein said adjacent portions comprise a shiplap flange;
- the leg shaped to transfer vertical forces to and from the end of the mating conduit and thereby decrease the tendency of mated conduits to separate and deflect at their mating joint under vertical forces.
