Abstract
A porewater pressure dissipater is disclosed. In one example, a disclosed dissipater includes aggregate; a cylindrical receptacle for receiving the aggregate; a plate having a top surface and a bottom surface and one or more openings transcending from the top surface to the bottom surface wherein the plate secures and compacts the aggregate in the cylindrical receptacle; and one or more access tubes coupled to the top surface of the plate wherein the one or more access tubes are positioned over the one or more openings thereby forming a passageway to the cylindrical receptacle. The disclosed dissipater allows piles and shafts to be embedded at the optimum depth without concerns of liquefaction.
Claims18
A porewater pressure dissipater, comprising:
- aggregate;
- a cylindrical receptacle for receiving the aggregate;
- a plate having a top surface and a bottom surface and one or more openings transcending from the top surface to the bottom surface wherein the plate secures and compacts the aggregate in the cylindrical receptacle;
- and
- one or more access tubes coupled to the top surface of the plate wherein the one or more access tubes are positioned over the one or more openings thereby forming a passageway to the cylindrical receptacle.
A method of assembling a porewater dissipater, comprising:
- arranging uniform or nonuniform aggregate in a cylindrical receptacle;
- coupling a plate on the cylindrical receptacle so that the plate compacts and seals the aggregate within the cylindrical receptacle wherein the plate comprises a top surface and a bottom surface and one or more openings transcending from the top surface to the bottom surface;
- and
- coupling an access tube to each of the openings within the plate, wherein each access tube is positioned around each opening to allow water to flow from a side or bottom surface of the cylindrical receptacle through the opening and into the access tube when in use, thereby forming an assembled porewater dissipater.
