Road pavement prefabricated part for protecting ancient trees and paving method

Abstract

The invention discloses a road pavement prefabricated part for protecting ancient trees, a paving structure and a paving method. The road pavement prefabricated part comprises a prefabricated part body, wherein the prefabricated part body comprises a full-hole type prefabricated part or a half-hole type prefabricated part; the full-hole type prefabricated part is regularly cubic; the full-hole type prefabricated part is hollow inside; a through hole is formed in each surface; the half-hole type prefabricated part is 1 / 2 of the full-hole type prefabricated part. During paving, the prefabricatedpart, improved soil, a retarded adsorption layer, a roadbed cushion layer and a pavement paving layer are combined to form the paving structure favorable for protecting the ancient trees. The problemof worsening of a living environment of tree roots due to treading in the prior art is solved. The road pavement prefabricated part can effectively protect ancient and famous trees from being treadedoften, and also can provide an extension space for extension of the tree roots, so that natural growth of the roots is facilitated. The invention is subsidized by the national forestry public welfareindustry science and technology special 'Key Technology Research on Protection of level-I Ancient and Famous Trees in the Middle Yellow River Area (201404302)'.

Description

technical field [0001] The invention relates to the technical field of tree protection, in particular to a road paving prefabricated part, a paving structure and a paving method for protecting old trees. Background technique [0002] The flow of people in the tourist area is huge, and the continuous trampling of tourists coming and going has a very negative impact on the ancient and famous trees and street trees in the tourist area. The most obvious is that it causes soil compaction under the trees, poor water permeability and ventilation performance, and soil enzyme activity. reduced, difficulty in nutrient supplementation, decreased root system activity and absorption capacity, and eventually caused the growth of ancient and famous trees to weaken, or even dry up and die. In addition, in order to facilitate tourists to visit, tourist areas often adopt improper measures such as hardening or laying impermeable floor tiles on roads and squares, which exacerbates the deteriora...
