Problems solved by technology

There is a large amount of red sandstone in the new road of a certain highway. Due to the particularity of the material itself, the whereabouts of a large amount of red sandstone excavation is in front of us. If it is not used as abandoned, it will cause waste of resources and increase investment. , the abandoned side will also occupy a large amount of land, causing water and soil conservation problems

Embodiment Construction

[0026] The present invention is illustrated below in conjunction with the accompanying drawings.

[0027] Such as figure 1 As shown, from bottom to top on the side of the road are the original red sandstone soil layer 1, geotextile 2, improved planting soil layer 3 and non-woven fabric 4, and the vegetation or maintenance 5 planted on the improved planting soil layer 3, the construction method is as follows :

[0028] Step 1. Analyze the particle size, particle analysis and physical and chemical properties of the red sandstone soil, and overturn the original red sandstone soil layer, break up large pieces of red sandstone soil, and then cover the geotextile to prevent rainwater loss.

[0029] Step 2, take another red sandstone soil, according to the properties of the red sandstone soil, mix different doses of improvers to form improved planting soil, the improver is carrageenan, humus, plant ash, etc., analyze the physical and chemical properties of the improved planting soil...

Abstract

The invention discloses a road red-sandstone soil improvement construction method. The method includes: analyzing the particle size, particles and physical and chemical properties of red-sandstone soil, turning and crushing an original red-sandstone soil layer of a road, and covering with geotextile; then, taking other red-sandstone soil, and mixing with different doses of an improving agent according to properties of the taken red-sandstone soil to form improved planting soil, wherein the improving agent comprises any one of carrageenan, humus and plant ash or a composition of several of thesame; uniformly spreading the improved planting soil to the geotextile, covering with nonwoven cloth, preserving soil moisture and fermenting for 2-3 days, and planting plants; after seedlings grow to10cm or above, removing the nonwoven cloth to allow the seedlings to grow naturally, so that road red-sandstone soil improvement construction is completed. By adoption of the method, effective components in the red-sandstone soil can be effectively improved, fertilizer leakage is prevented, various essential nutrient substances to plants in original soil are improved, an effective component ratiosuitable for plant growth is achieved, and lasting virtuous cycle is formed.

Description

technical field [0001] The invention belongs to the technical field of road maintenance, transformation and material reuse, and relates to a soil improvement method, in particular to a road red sandstone soil improvement construction method. Background technique [0002] Due to the rapid development of transportation in recent years, the original road network composed of national highways and provincial highways can no longer meet the requirements of road transportation industry and economic development, and the construction of a large number of roads in various provinces and cities has become inevitable. There is a large amount of red sandstone in the new road of a certain highway. Due to the particularity of the material itself, the whereabouts of a large amount of red sandstone excavation is in front of us. If it is not used as abandoned, it will cause waste of resources and increase investment. , The abandoned side will also occupy a large amount of land, causing water a...
