Cliff Reinforcement
Cliff Reinforcement
(OP)
Problem: A transmission tower was built near a cliff and this past few months due to heavy rains, parts of the cliff have eroded. So cliff reinforcement in in order. The tower's leg is about 8m from the edge. The cliff is about 19m high with a creek about 3m wide at the bottom. The cliff has a near vertical slope. I am lookng at soil nailing technology to reinforce the cliff. Got any good ideas? Thanks.

first , to keep all the underground water away from the cliff, we constructed a underground drainage, with geotextile, crusched rock, and perforated pipes , as close as possible to the edge. Then with the help of a Samsung 280 excavator we constructed a series of benches to distribute the weight, also we constructed some culverts to keep the water from running over the slopes in quantities, also all the surrounding area around the tower was covered with a thing slab of concrete to prevent water to get into any crack of the soil and further water accumulation underground. These measures were taken a year ago, and the land slide and the erotion stopped, so i hope that some of these can help you, i have a problem too, and i posted it so if you can take a look i will appreciate it.

We have had success locally containing rivers that run through residential neighborhoods using rock baskets.
A rock basket is a simple cage made of galvinized fencing that is filled with river rock and can be stacked to form a wall. They're not pretty, but it's cheap. In your case, they may be of use on the outside bend of the river, dissapating the energy of the river, and preventing erosion at the toe of the slope. If the soil is stable enough to be cliff-forming, it sounds like you have a good chance of success.
I would be interested in a follow-up to this discussion on how it turns out. Best of luck.
