Slope maintenance method

Abstract

The invention relates to a slope maintenance method. The slope maintenance method comprises the following steps of (1) fixing non-woven fabrics on a slope sown with seeds, and performing watering maintenance on the slope; wetting soil with the depth of 12-18cm during maintenance for the first time; keeping a surface layer, with the depth of 6-7cm, of the soil moist after 18-20 days; and removing the non-woven fabrics when the heights of vegetations on the surface of the slope are 5-10cm, watering the vegetations three times every week, wetting the soil with the depth of 1-2cm every time, and guaranteeing that the total watering time is not less than 30 days; (2) performing topdressing according to N:P:K=1-2.5:0.5-1.5:15-20g / m(2) during seedling stage of the vegetations on the slope, and performing topdressing according to N:P:K=8-12:6-8:4-6g / m(2) after seedling; and (3) spraying broad-spectrum agents during seedling stage of the vegetations on the slope. By using the slope maintenance method, field experiences are combined with experiments; a feasible solution is provided for solving the problem that later maintenance is difficult in a slope spraying technology; and the slope maintenance method facilitates greening of the domestic slope engineering.

Description

technical field [0001] The invention relates to the technical field of road maintenance, in particular to a method for maintaining slopes. Background technique [0002] As the country strengthens the management of geological disasters and dangerous slopes, human beings’ requirements for the living environment continue to increase. Some slopes with potential safety hazards will be stabilized after treatment, but the vegetation will be severely damaged. , The soil will be exposed in large quantities, forming strong visual pollution, which is not in harmony with human requirements for the environment. Now spraying greening technology has become a routine means of slope ecological restoration. Compared with the previous greening scheme, the soil and vegetation cannot be fixed on the bare rock, and the vegetation planted in the soil layer after slope cutting is not easy to survive due to the damage of nutrition and environment. Therefore, spraying slope protection technology is...

Problems solved by technology

However, many construction units do not pay much attention to this issue due to cost considerations. The fundamental reasons are: (1) In places with high slopes or water shortages, watering and maintenance are more difficult. Due to the high slope, it is difficult for the pump to pump to the required level Height; (2) The cost of pulling water from a long distance is very high; (3) Many construction units think that the grass has grown, and the task is completed, and maintenance is not a big deal, and they do not pay attention

In fact, many spray-seeding greening projects were successfully constructed in the early stage, but the grass seedlings died due to poor maintenance in the later stage, which eventually led to the failure of spray-seeding greening
