1 and 2, according to the natural-friendly vegetation revetment construction method according to the present invention, first excavated along the excavation line below the planned riverbed height (100) of the river to be constructed, the outflow of the rear soil To prevent the soil outflow prevention member (for example, geotextiles) 101 to prevent the installation on the inclined surface of the lower surface formed by the trench, and filling the natural stone 102 of a relatively large standard in the recessed lower portion of the inclined surface The gap between the natural stones 102 is filled with rubble 103 and then flattened to form a proximal end.

In this way, when the construction of the proximal end is completed, a plurality of pile members 104 are installed in the transverse direction along the lower eye on the constructed proximal end. At this time, the pile member may be used for thinning timber or preservative factory production wood. In addition, for the connection between the lateral pile member 104 and the lateral pile member 104, as shown in FIG. Can be. In interconnecting the lateral pile members 104 using this connector (clamp) 301, the connection (joint) position is not positioned continuously on the same vertical line. That is, the connector (fastener) 301 is fastened so that the connection position is located in a zigzag form. This is to increase the structural stability by preventing the concentration of stress.

When the installation of the lateral pile member 104 is completed, a plurality of longitudinal pile members 105 are installed on the lower eye slope in the longitudinal direction so as to be spaced apart from each other by a predetermined interval immediately above the lateral pile members 104, and in the lateral direction. The pile member 104 and the longitudinal pile member 105 are fixed to each other by binding. At this time, in installing the longitudinal pile member 105 on the inclined surface of the lower eye, the horizontal pile member 105 is spaced apart from each other by a predetermined interval to maintain the same level horizontally, but the upper and lower ends are not continuously positioned on the same vertical line but are zigzag mutually. Install it on the inclined surface so that it is positioned in the form. This is to increase the structural stability by dispersing the upper stress. In addition, as shown in FIG. 4 for coupling the horizontal pile member 104 and the longitudinal pile member 105, a fastening method using a bolt 401 and a nut 402 may be used. Then, the transverse pile member 104 and the longitudinal pile member 105 are selected to have the same diameter or the same cross section if possible. In addition, the front slope of the vegetation lake to be prepared is variously determined according to the diameter of the pile member and the horizontal separation distance of the upper and lower horizontal pile member 104. In addition, the length of the longitudinal pile member 105 protruding forward of the lateral pile member 104 is arbitrarily determined according to the shore condition.

When the installation of the longitudinal pile member 105 is completed, the soil 106 is filled and compacted on the rear surface of the horizontal pile member 104. At this time, as the soil 106 to be used is preferably good quality sandy soil is used, compacted to a compaction density of 85%.
