Description
Technical Field
The invention relates to the field of landscape lifting for ecological restoration, in particular to a rapid ecological restoration landscape lifting method for stone cage protection slope of an original river channel.
Background
With the increasing importance of the country on the ecological environment management, the requirements of people on the quality of life are also higher and higher. In the traditional river channel gabion stone cage revetment, although flood discharge safety and side slope stability of the river channel revetment are ensured, certain visual pollution is caused. The traditional gabion slope protection greening scheme is broadcast seeding slope protection greening, and the main planting mode is grass seeding and ground cover seed seeding. The construction process needs to perform manual full-joint soil filling and tamping on the stone cage before sowing (sieving humus soil, peat soil and slow-release nutrient fertilizer are mixed uniformly, filling the humus soil, peat soil and slow-release nutrient fertilizer into gaps of the stone cage slope protection for multiple times, watering until the soil is filled into the gaps of the stone cage slope protection), covering 10mm of the whole stone cage slope protection after the gap filling, covering 1mm of thin soil for the second time after the sowing is finished, watering and soaking, moisturizing and preserving the heat for at least one month by adopting a geotextile after the sowing and soaking is finished, and preferably sowing in spring. The construction process has low efficiency of manual full-joint soil filling and tamping in the construction process and has poor effect of tamping not easy to be full; the slope surface of the slope protection is longer, earthwork can be only unloaded to the top of the slope surface by a loader and then covered with soil by a large amount of manpower by using tools such as rakes and shovels, the manpower efficiency is low, uneven soil covering is easily caused, and the slope protection of the river-facing gabion is operated by a large amount of manpower, so that potential safety hazards are easily formed; the moisture preservation and heat preservation in the later period are troublesome, and the construction is carried out in the best season of broadcast planting in summer and not in spring at that time.
Therefore, how to improve the construction efficiency and the landscape effect and ensure long-term greening needs to adopt a more advanced, rapid, stable and beautiful river slope protection method for improving the ecological restoration landscape.
