A construction method for an easily movable/installable decompression drainage system is provided to construct a decompression drainage system by a basin quickly and simply by changing the location of a decompression structure easily after forming a lean concrete layer using a connection structure. A construction method for an easily movable/installable decompression drainage system, which contains a decompression structure and a connection structure, comprises the steps of forming a drainage space(50) or a drain board(40) on the upper or lower part of an excavation plane(2), connecting the drainage space or the drain board with a connector(30), forming a lean concrete layer(4) by placing concrete while connecting with the connector to make the open top of the connector exposed to the upper part of the lean concrete layer, hardening the lean concrete layer and placing a decompression structure(10) on the wanted location and connecting the open top of the connector and the decompression structure using a connection structure(20) such as a pipe or a hose to be regulable in length and direction. |
