INSTALLATION METHOD OF HORIZONTAL DRAIN MATERIAL FOR IMPROVING SOFT GROUND

PROBLEM TO BE SOLVED: To provide an installation method of horizontal drain material for improving a soft ground capable of reducing works at a construction site and horizontally installing a horizontal drain material economically and effectively. SOLUTION: An installation method of horizontal drain material is that a prescribed quantity of drain materials 10 which is to be installed in a horizontal direction is one unit as a drain material unit A, the drain material unit A which is connected with a prescribed interval length between the drained materials adjacent each other via drain material connectors 11 which correspond to a desired installation interval length is used, the drain material unit A is winded as a roll state that the interval of the connected drain materials 10 is shorter than the installation interval, is carried in the installation site in the rolled state of being winded, and, while the drain material unit which is winded in the rolled state is winded back and the edge of the drain material unit is drawn out, the drain material unit is drawn out to the surface of the soft ground by widening the interval of the drain material to the same length of the drain material connectors.
