A method of installing a trench for containing a cryogenic spill, including the step of constructing multiple precast concrete sections at a first location, each section preferably having a bottom wall and spaced apart side walls connected to and extending up from the bottom wall. Each section preferably has end portions that enable connection to another said concrete section. The method includes (at the first location) preparing multiple panels of polymeric concrete material by filling one or more molds with a slurry or liquid polymeric concrete material and after time allowing the material to cure and harden. The mold can have a cavity that is lined with a release material. At the first location, one or more of the panels can be adhered to the bottom wall and side walls of each concrete section preferably using an adhesive. After adhering of the panels to the concrete sections, the concrete sections can be transported from the first location to a second location that is remote from the first location. At the second location, the concrete sections are connected together using connections that preferably join one end portion of a concrete section to and end portion of another concrete section. An epoxy grout is preferably field applied to the connections at the second location.

A drainage channel support assembly including a support member adapted to support drainage channel, a pair of pegs arranged to anchor the support member to the ground, and a pair of coupling elements mounted to respective of each of the pair of pegs. The coupling arrangements are configured where on anchoring of the support member to the ground via respective of the pair of pegs either: in a first install mode, the coupling arrangement contacts an upper surface of the support member with the associated peg penetrating the ground along substantially the full length of the peg; or, in a second install mode, the coupling arrangement couples to a fitting which contacts the upper surface of the support member, the coupling arrangement contacting a lower surface of the support member for suspension of the drainage channel above the ground.

A method of treating a pond, lake or other body of water to improve the retention of water includes treating the ground at the bed of the pond with bentonite clay, a super absorbent polymer, a polysaccharide, and a polymer flocculant. The bentonite clay can be granulated #16 Wyoming bentonite clay, the super absorbent polymer can be granulated polyacrylamide, the polysaccharide can be granulated carboxy methyl cellulose, and the polymer flocculant can be a high-performance polymer flocculant, such as 2-Propenoic Acid, polymer with 2-Promenamide, sodium salt 90-100%.

The present invention is directed broadly to a drainage channel support assembly 10 comprising a support member 12 adapted to support drainage channel 14, a pair of pegs 16a and 16b arranged to anchor the support member 12 to the ground, and a pair of coupling elements 18a and 18b mounted to respective of each of the pair of pegs 16a and 16b. The coupling arrangements 18a and 18b are configured where on anchoring of the support member 12 to the ground via respective of the pair of pegs 16a/b either: 1. in a first install mode, the coupling arrangement 18a contacts an upper surface of the support member 12 with the associated peg 16a penetrating the ground along substantially the full length of the peg 16a; or 2. in a second install mode, the coupling arrangement 18a couples to a fitting 22a which contacts the upper surface of the support member 12, the coupling arrangement 18a contacting a lower surface of the support member 12 for suspension of the drainage channel 14 above the ground.

A method for stabilizing and lifting a channel board by underwater grouting includes (A) when the channel board is damaged, removing the damaged channel board, cleaning and leveling a gravel layer under the damaged channel board, placing an undamaged channel board installed with first grouting pipes and a second grouting pipe on the gravel layer, wherein multiple geotextile bags are respectively bound to the first grouting pipes; when the channel board is subsided, installing first grouting pipes and a second grouting pipe into first grouting holes and a second grouting hole, respectively; (B) performing a first polymer grouting through the first grouting pipes, and performing a second polymer grouting through the second grouting pipe; (C) cutting off a part of the first grouting pipes the second grouting pipe which are exposed to the channel board, and leveling incisions; and (D) removing excess polymer left on the channel board.
