Title:
DRAINAGE PRESSURE RELIEF ANTI-FLOATING SYSTEM FOR WEAKLY PERMEABLE SOFT STRATUM
Document Type and Number:
WIPO Patent Application WO/2023/103651
Kind Code:
A1
Abstract:
Disclosed in the present invention is a drainage pressure relief anti-floating system suitable for a weakly permeable soft stratum. The drainage pressure relief anti-floating system comprises a pressure relief well body and an artificial hydrophobic layer, wherein longitudinal bars are arranged in stand columns of a sand-free concrete well wall, and are anchored into concealed beams. The pressure relief well body is located in the artificial hydrophobic layer, a construction surface of the artificial hydrophobic layer is located on the weakly permeable soft stratum, a wicker fence layer is laid on the weakly permeable soft stratum, a biaxially stretched plastic geogrid is laid on the wicker fence layer, a medium coarse sand layer is laid on the biaxially stretched plastic geogrid, and a crushed stone layer is laid on the medium coarse sand layer, such that the problems of a small precipitation funnel when a pressure relief well drains water in a weakly permeable stratum, well settling, difficulties in carrying out construction in a soft earth layer, particularly construction during the rainy season, and soil conservation and silt prevention of a pressure relief well in a silt formation are solved; and a buoyancy borne by a structural floor in the weakly permeable soft stratum is reduced, and the cost of arranging traditional anti-floating facilities in the weakly permeable soft stratum is greatly reduced.
