[0022] FIG. 2 details the open state of the polymer net 3 of the flexible rope net gabion 5, having a conical top end and open bottom end. The polymer net 3 comprises of two lacing twines 31A and 31B. The twines 31A and 31B are configured for facilitating tying of the open end after filling the polymer net 3 with stones of boulders 4.

[0023] The polymer net 3 is further adorned with a bottom 10 mm twisted polyester rope 34, disposed close to the top open end, which functions as a load-bearing portion for hanging to hook 1. The polymer net 3 further comprises of multitude of structural ropes 33, which are 6 mm polyester twisted ropes. The structural ropes 33 extend from the top 10 mm twisted polyester ring 32 till a top 10 mm twisted polyester rope ring 34. In accordance with this embodiment the 34 has a diameter which is substantially larger than the diameter of top 10 mm twisted polyester rope ring 34, such that the structural ropes 33 along with the rings 32 and 34 form a substantially conical structure.

[0024] As illustrated in FIG. 3, the flexible rope net gabion 3 packed with rock to an extent of 45% allows the flexible rope gabion 3 to be evenly positioned around the structure 100 to be supported thereby ensuring that it is anchored in a balanced fashion.
