RESERVOIR CONSTRUCTION METHOD Russian patent published in 2005 - IPC

FIELD: building, particularly to construct reservoirs on weak ground.

SUBSTANCE: method involves preparing building site and ground base; mounting reservoir and performing hydraulic tests thereof. Reservoir mounting is performed in several stages. At the first stage reservoir is built without stationary metal bottom, has projected edges and is provided with temporary flexible bottom air-tightly pressed against projected edges with the use of pneumatic system. After that preliminary hydraulic tests are performed by filling reservoir with water. At the second stage temporary flexible bottom is demounted after complete ground base compaction, deformed ground base is smoothed up to reaching design mark by filling the formed cavity with filling material. Then waterproofing material is applied to smoothed base, permanent metal bottom is formed and the ready vessel is subjected to final hydraulic tests.

EFFECT: reduction of absolute ground base sediment and non-uniform deformation of load-bearing structure, increased operational reliability.
