Formula and processing method of overpass substrate for garden engineering

Abstract

The invention discloses a formula and processing method of an overpass substrate for garden engineering. The formula is prepared from the following components in percentage by mass: 25% to 35% of garden fermentation materials, 15% to 25% of washed cow dung fermentation materials, 45% to 55% of yellow mud and compound fertilizer. The formula and processing method of the overpass substrate for garden engineering has the beneficial effects that after the garden fermentation materials and the cow dung fermentation materials are mixed with original soil, the overall porosity of a product is 45% or above; slow seedling and fertilizer and water management in the later stage are facilitated, the load-bearing requirement of an overbridge container is greatly reduced, construction operation is simple, re-cleaning such as on-site mixing or pulling of the original soil to dirty a road surface is not needed, seedlings can be obtained by directly disassembling bags and pots, seedling recovering and rooting are facilitated, the later-stage fertilizer and water management can completely adapt to drip irrigation, and therefore follow-up maintenance is facilitated; and moreover, during production, the proportion of various raw materials can be ensured to be accurate to millesimal, the buffering property can be improved by matching the proportion of the various raw materials and the properties of various materials, and the physicochemical properties among batches are also very stable.

Description

technical field [0001] The invention relates to the technical field of flyover substrate formulations, in particular to a landscape engineering flyover substrate formulation and a processing method thereof. Background technique [0002] With the popularization of urbanization, the city's supporting facilities and infrastructure also need to be followed up. In order to facilitate people's travel, a flyover needs to be erected. After the flyover is completed, it needs to be greened. The existing construction parties are municipal engineering construction. Supplement organic matter and yellow mud according to requirements, but the mixing of organic matter and yellow mud is extremely uneven, and the proportion of mud is too large to meet the requirements of improving the planting environment. In addition, direct landfill covering yellow mud will increase the bridge body The heavy load and the use of single materials lead to two extremes of fast or slow degradation speed, and the...

[0002] With the popularization of urbanization, the city's supporting facilities and infrastructure also need to be followed up. In order to facilitate people's travel, a flyover needs to be erected. After the flyover is completed, it needs to be greened. The existing construction parties are municipal engineering construction. Supplement organic matter and yellow mud according to requirements, but the mixing of organic matter and yellow mud is extremely uneven, and the proportion of mud is too large to meet the requirements of improving the planting environment. In addition, direct landfill covering yellow mud will increase the bridge body The heavy load and the use of single materials lead to two extremes of fast or slow degradation speed, and the lack of organic matter supplementation will cause serious hardening in about a year, resulting in quality problems
