Method for arranging arbor to multi-layer stratified solid waste

Abstract

The invention provides a method for arranging arbor to multi-layer stratified solid waste. The method uses the coarse solid waste as a foundation, and forms at least one set of foundations including aconcave and a convex surface which are alternately formed alternately, and the concave surface is a tree planting hole; according to the two types of coarse green plant waste and fine green plant waste, the plant residues, weeds, fallen leaves and branches are crushed. The method comprises digging the original soil, adding the improved soil imported from other places, the organic-inorganic improving material and the microbial agent to the original soil of the site to form the matching soil for use. The method utilizes the site after the excavation of the original soil, and the concave surface, which is, the planting cavity portion, from the bottom layer to the surface layer, filling a fine solid waste layer, a coarse green plant waste layer, a fine solid waste layer, a fine green plant waste layer and a matching soil layer respectively. The method comprises covering soil, planting arbor plants, and completing the multi-layer stratification and dissolving solid waste by planting trees.The technical solution reduces the cost of improving the soil physical structure of the project site with significant environmental protection effect of recycling.

Description

technical field [0001] The invention relates to an ecological utilization method of solid waste of buildings, in particular, the solid waste is used to reduce soil salinity and obtain economic effects. Background technique [0002] Urban landscaping is an indispensable and important component of urban ecological environment construction and maintenance. However, due to the continuous shrinkage of urban land resources, a large number of cities will use sites with a large amount of solid waste and environmental pollutants such as construction in the future. At the same time, there are generally problems such as poor soil and sticky soil in the site, which has a negative impact on the planting and growth of green plants. At the same time, transporting and landfilling solid waste such as site buildings not only increases investment, but also wastes land resources after landfilling. At present, urban greening projects generally take a small amount of landform construction and mo...

AI Technical Summary

Problems solved by technology

Landfilling of solid waste requires a large investment in treatment and transportation costs, resulting in unnecessary waste

At the same time, there is a certain degree of secondary pollution risk; simple use for terrain construction may result in poor nutrients in the deep soil, which is not conducive to the subsequent growth of arbor plants

[0003] In addition, soil improvement is generally carried out before the planting of greening engineering plants. Compost products, litter and crushed leaves and other improvement materials are used to improve the soil with a thickness of 60-80 cm on the original site. Insufficient depth of regional improvement and other issues
