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 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%.

A method for regulating and controlling discharge flow of a dammed lake includes steps of: (S1) estimating a most dangerous discharge condition; (S2) based on the most dangerous discharge condition, calculating a structural internal force of the steel flexible net; (S3) based on the internal force of the steel flexible net, calculating an anti-slide embedded depth at two sides of the steel flexible net; (S4) based on the most dangerous discharge condition, manually excavating a channel; and (S5) based on the anti-slide embedded depth at the two sides of the steel flexible net, embedding the steel flexible net into a barrier dam. According to the present invention, the steel flexible net is laid on the upstream slope of the barrier dam, two sides of the steel flexible net is embedded into the slope body with gravels of the barrier dam, and cooperates with the channel for usage.

A construction method and operational process for the implementation of a condominium and/or subdivision with the creation of artificial beaches for bathing in the format of isles and/or peninsulas and/or bays and/or lakes and/or the like is disclosed. More precisely, the construction method for the implementation of a condominium and/or lot subdivision, includes blocks (Q) of lots (L) in the format of an isle (I) and/or peninsula (P), allowing the implementation of watercourses (1) forming said isles (I) and/or peninsulas (P), that contains the lots (L) of the condominium, with the formation of artificial beaches (2) in the perimeter of said lots (L) composing said subdivision. The watercourses (1) are appropriate for contemplation and bathing by the condominium members, including the possibility of creating waves or ripples (18).
