STONE NET FOR RIVER BULKHEAD AND THIS CONSTRUCTION TECHNIQUE

摘要

A vegetation stone net for river revetment and slope protection, and a construction method of a vegetation stone net for river revetment and slope protection are provided to heighten constructability by installing a vegetation stone net variously according to the speed of a current and topographical features at an incline or a riverside slope for public works, fulfilling the function of vegetation with a vegetation sheet and making mechanized construction possible, to be stabilized structurally by unifying all structures, to protect a slope effectively by preventing the outflow of small pebbles when using a grid, and to be excellent ecologically by rooting plants suitable for the circumstances of the field and heightening environmental performance. A vegetation stone net(M) for river revetment and slope protection comprises a block(10) made of native stone or imitation stone, a vegetation sheet(20) placed on the lower part of the block in the appointed width and length and attached with seeds(22) at the surface, a coir mat(30) placed between the block and the vegetation sheet, made of coconut shells and weaved by jute in a lattice type, a grid(40) placed n the lower part of the vegetation sheet and formed in a mesh type, and a set anchor press-fitted to the block through the grid. A construction method of a vegetation stone net for river revetment and slope protection comprises the steps of: paving and tamping foundation stones to secure bearing capacity of the foundation ground; forming a foundation concrete layer by placing and curing concrete on the foundation stones; installing a vegetation stone net on a slope of the foundation concrete layer; forming a crown concrete layer by placing and curing concrete to the appointed thickness on the uppermost end of the vegetation stone net; and covering the surface of the vegetation stone net with the surrounding soil.
