The present invention relates to an aqueduct leakage repairing method, a formwork is provided within an aqueduct body; a reinforcing layer is formed by using the formwork through casting at inner sides of the aqueduct body; the formwork comprises side formwork plates, bottom formwork plates, and axillary angle formwork plates; the side formwork plates are arranged at inner vertical walls of the aqueduct body, the bottom formwork plates are arranged on a bottom of the aqueduct body, the bottom formwork plates are connected with the side formwork plates through the axillary angle formwork plates; and the axillary angle formwork plates are each provided with a plurality of ribs. The aqueduct leakage repairing method effectively reinforces penetration damage of the aqueduct, and the construction process is simple since the formwork is free from dismantling after construction.

A membrane-lined wall for levee reinforcement or leak prevention, prevention of water migration, and pollution control of impoundments. The membrane-lined wall generally includes a cementitious or concrete wall formed within an excavated trench. The concrete may be internally reinforced, and the wall may also comprise a double-layer of impermeable geomembrane liner that forms a barrier between the concrete and the sides and bottom of the trench. The membrane or liner reduces water migration, prevents levee leakage, and prevents the escape of contaminants in impoundments.

Disclosed is an improved flexible flood barrier system for creating a watertight barrier. The system includes a novel hinged clamping bar assembly configured to engage a hem of the fabric flood barrier. The fabric flood barrier is comprised of a waterproof layer reinforced with Kevlar straps. The Kevlar straps are weaved together through slots in one of the layers without the need for stitching upon any of the waterproof layers. When deployed the improved fabric flood barrier system prevents storm surges from breaching the flexible flood barrier system at the attachment points.

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 cemented material dam construction based on whole-process quality control includes: determining a water-binder ratio of a sand and gravel material through a simulation test; laying rockfill on the first cemented sand and gravel layer before the final setting time of the first cemented sand and gravel layer; adjusting the maximum particle size of the rockfill and the distance between the particles in the rockfill according to the design requirements; spraying a cement slurry on the rockfill to wrap all the particles in the rockfill and laying a second cemented sand and gravel layer before the initial setting time of the cement slurry; performing rolling compaction on the construction layer until the decline in the thickness of the construction layer and the apparent density of the rolled surface meet the design requirements; and completing the cemented material dam construction.
