Prefabricating and using method of planting growing building block for ecologically repairing exposed slope

Abstract

The invention relates to a prefabricating and using method of a planting growing building block for ecologically repairing an exposed slope. The method comprises the steps of mixing ecologic concrete, sand, crushed stone and water according to a certain proportion, casting, internally arranging plant growing channels, and piling to finally form a netty and continuous channel system which can be filled with green plant growing base materials and distributed with drop irrigation or filtration irrigation pipelines, wherein the plant growing channels can be intersected and communicated among the building blocks. The plant growing piling has the advantages that both the engineering protection action of a traditional mortar rubble method and the ecologic slope fixing and protecting and landscape construction effects of a hanging net soil dressing spraying mixing plant growing method are realized, modular operation and timely greening are realized, the defects of the mortar rubble method and the hanging net soil dressing spraying mixing plant growing method are overcome, the base materials are effectively prevented from sliding and being washed by rainwater, construction and maintenance are facilitated and the like; the plant growing building block can be widely used in the economic repairing and protection of road side slopes, exposed mountain bodies, riverway banks and the like and has a broad application prospect.

Description

technical field [0001] The invention relates to a planting block for ecological restoration of exposed slopes, more specifically, to a planting block with ecological concrete, sand, and gravel as the basic pouring materials, with a planting channel inside, which can be operated in a modular manner and can be greened immediately The prefabrication and use method of the vegetation block. Background technique [0002] my country is a mountainous country, and the total area of ​​mountains, hills and relatively rugged plateaus accounts for about two-thirds of the country's land area. At the same time, my country is a country with frequent geological disasters, and the area of ​​water and soil erosion exceeds half of the country's land area. The agricultural development of mountain areas and the large-scale construction of various projects, such as roads, railways, water conservancy, mines, and industrial and civil buildings, will cause a series of environmental problems, the mos...

AI Technical Summary

Problems solved by technology

However, in the actual application process, due to reasons such as unreasonable excavation of some slopes and excessive rainwater during construction, there have been some problems and defects that are difficult to overcome by the hanging net guest soil spraying mixed planting method itself, such as: (1) Slope The surface is too steep, and the slope ratio is greater than 1:0.75. It is difficult for ordinary spraying technology to firmly attach the spraying substrate; (2) The excavation of the slope is not smooth, and it is difficult for ordinary spraying and hanging nets to adhere to the slope; (3) South China The rainy season is long and the instantaneous rainfall is large, which is difficult for the construction in the rainy season, and the erosion is serious; (4) The fertility supply of the substrate attached to the slope is not durable, and the vegetation is easy to degrade, which is not conducive to the long-term stable growth and succession of vegetation

The existence of these defects directly affects the stability of the slope, the effect of slope reinforcement and slope protection, and the ecological landscape, and it is difficult to overcome through the technical improvement of the method itself.
