The staircase mountain re-greening project is more than 180 meters above the ground and is extremely steep, which is one of the most difficult mountains in Liuzhou for ecological restoration.
Workers replanting bougainvillea saplings.
Carry out management work on cliffs covered with greenery and flowers.
Workers climbed up a ladder up a 100-meter-high mountain.
The width of the cement slab groove of the cliff is only about 1 meter, and the workers need great courage when working.
Engineers are inspecting the sprinkler system.
Workers check the viability of the saplings on the slab trough.
In the warm sun of Liuzhou in winter, located on the staircase hill near Xueyuan Road, the bougainvillea in the plate groove is in full bloom. Worker He Dingqing and his co-workers once again climbed the "ladder" erected along the cliff and began a new round of green planting and management and protection operations.
The total investment of the staircase mountain re-greening project is more than 50 million yuan, which started in September 2018, passed the preliminary acceptance on April 23, 2021, and then entered the stage of green plant management and protection, with a treatment area of 225,000 square meters, a mountain slope of 70 degrees to 90 degrees, and a vertical height of more than 180 meters above the ground at the highest point, which is one of the most difficult mountains in Liuzhou for ecological restoration.
"We have planted more than 250,000 seedlings of all kinds on the mountain." Chen Chaoyu, project manager of the project, said that the workers need to first clean the rocks that are at risk of tumbling, then use steel and concrete to build V-shaped plate troughs on the cliffs, and then backfill the soil for the "terraces" opened up, and lay a spray system in the "field" before they can be planted. At present, the seedlings planted include Stone Mountain Purple Weed, Oleander, Stone Mountain Banyan Tree, Climbing Tiger, Bougainvillea, Rhododendron and so on.
He Dingqing, a worker who has been on the construction site for more than 3 years, still has a lot of feelings when he recalls the greening process of this mountain. He said: "In order to ensure the safety of construction, we went up along the mountain and hit a ladder more than 100 meters high on the cliff with steel nails, and everyone said that this was the 'ladder' for the workers' operation; and then around the mountain, we used a wire rope to pull up more than 40,000 meters of safety rope on the cliff, and the foreman said that this was the lifeline of the workers." ”
"Conservation operations are the last stage of the mountain ecological re-greening project, and we must ensure that more than 90% of the green plants can survive." Chen Chaoyu said that the maintenance work is mainly to repair the water supply pipeline and replant the seedlings, which will last for one year.
In recent years, Liuzhou City has actively practiced the development concept of "green water and green mountains are golden mountains and silver mountains", and taken many measures to carry out green ecological restoration of abandoned mines and mountains left over from history. According to reports, Staircase Hill is the 16th abandoned mine in liuzhou city for ecological restoration. At present, the total area of mines in the urban area has completed ecological restoration of 64 hectares, and 98 hectares of land around the mine have been revitalized and utilized after restoration. The "scars" of the former city are becoming a new ecological landscape with forests and scenery.
