Feb 7, 2020 · Stone pitching is an important technique for pathways and trails in upland areas as it allows for safe passage across steep terrain. The method involves stacking interlocking stones, using their flattest side up, to create small irregular steps that blend into the landscape.
Dec 10, 2020 · STONE PITCHING work shall consist of covering the slopes of Guide bunds, road embankments with stone, boulders over granular material called filter.
This section covers the requirements for: wire mesh gabions filled with stone and for the filter cloth on which they may be laid; stone and precast concrete block pitching for surface protection; (iii) rip-rap for slope protection.
GABION WALL. Gabion walls are suitable for retained heights typically up to about 10 m. Gabions are large rectangular cages or baskets, made of hexagonal woven steel wire or square welded mesh, filled with stone. Gabions are used to build retaining walls, revetments, and anti-erosion works.
The document provides methodology for stone pitching or revetment on slopes. It discusses preparing the slope surface, laying a filter layer, and placing stones closely in courses from the slope toe upward.
Dry Stone Pitching or Revetment: It is generally provided to protect the slopping face of an earthen cutting or embankment from erosion. Stones used, should be perfectly sound and roughly cut to fit in the shape of the pitching.
