A trough plate for constructing a locked polymer anti-seepage wall includes a plate body, a guide tube, a grouting pipe and an anti-blocking head. A construction method of the locked polymer anti-seepage wall includes the steps of positioning an N.sup.th trough plate and then pressing the N.sup.th trough plate into ground, wherein N is a natural number larger than and equal to 1; engaging an (N+1).sup.th trough plate with the N.sup.th trough plate, and then pressing the (N+1).sup.th trough plate into the ground; connecting a grouting pipe of the N.sup.th trough plate with a grouting machine, pulling out the N.sup.th trough plate, and simultaneously grouting through the grouting pipe of the N.sup.th trough plate by the grouting machine; and repeating the steps (B) and (C) till the locked polymer anti-seepage wall is completed, wherein the steps (B) and (C) are repeated every time, N is automatically increased by 1.

An apparatus and method for endwise connecting subterranean barrier members is disclosed. The apparatus includes at least two barrier members with each barrier member extending between top and bottom edges. Further, each barrier member has a side first edge having a flange defining a first connector and an opposed second side edge having a channel defining a second connector. The channel is sized and shaped to receive the flange of an adjacent barrier member in slidable interconnection therein. The apparatus further include a first side panel shaped to lie against a first side of the barrier members, a second side panel shaped to lie against a second side of the barrier members and a bridging plate located between the first and second panel members so as to bridge a gap therebetween, wherein the gap has a width corresponding to a width of the first and second barrier members. The associated method is directed toward creating the apparatus.

The present invention discloses an end plate system for joining spun piles together comprises a top end plate (100) mounted at a bottom end of a first spun pile: and a bottom end plate (200) mounted at a top end of a second spun pile; wherein the end plates (100, 200) respectively have an interlocking surface that is formed with a plurality of segmental protrusions (110, 210) and segmental recesses (120, 220) arranged in an alternate configuration; characterized in that each segmental protrusion (110, 210) has a first radial interlocking profile (111, 211) and a second radial interlocking profile (112, 212) that extend towards the central portion of the end plates (100, 200); wherein the top end plate (100) and the bottom end plate (200) are mated by registering the segmental protrusion (110, 210) of one end plate to the segmental recess (120, 220) of another end plate and through a rotating movement about the central axis of the mated end plates (100, 200), a first interlocking joint (300) is formed by two adjacent first radial interlocking profiles (111, 211) in full surface contact, and a second interlocking joint (400) is created by inserting a pin (402) into a passageway (401) formed between two adjacent second radial interlocking profiles (112, 212).

This patent pertains to secondary containment systems. One implementation includes a support assembly that includes an elongate post member and a stabilization plate. In one instance, a stabilization plate is mounted on the elongate post member to reduce movement of the elongate post member when the stabilization plate is embedded in the ground. Another implementation includes a panel splice assembly including reinforcing members that secure overlapping, corrugated panels.
