A combined tree hole cover and its application

Abstract

The invention relates to a combined type plant pit cover plate and application of the combined type plant pit cover plate, and belongs to the technical field of border tree plant pit covering. The combined type plant pit cover plate and the application are characterized in that the combined type plant pit cover plate is formed by an adjustable cover plate surrounding a tree trunk and a peripheral adjusting cover plate in a combined mode, and the size and the shape of a plant pit hole can be changed by the combined type plant pit cover plate according to the requirement. Small square plates same in number are respectively arranged at the splicing positions of the combined type plant pit cover plate, and hollow circles different in diameters can be expanded; small square plates same in number are arranged at the splicing positions of the combined type plant pit cover plate according to the requirement in the single direction, and hollow circles can be expanded into the hollow circles different in diameters. The combined type plant pit cover plate has the advantages that materials for making the plant pit cover plate are not cast iron, and scavengers cannot be used for achieving other functions; the materials are not replaced by plastic, and the environment cannot be polluted during production; by means of the combined type plant pit cover plate, a cover plate component combination is easily changed; the combined type plant pit cover plate can be suitable for different requirements of excavated border trees, and is smooth and attractive and resistant to grinding; by means of the plant pit cover plate, reliable covering is provided for soil surfaces of the plant pits of the border trees for municipal administration sidewalks; the plant pit cover plate is durable, attractive in model and good in effect.

Description

technical field [0001] The invention belongs to the technical field of street tree hole covering, and specifically relates to a technology for designing, manufacturing and using a street tree hole cover plate. Background technique [0002] As a covering facility for the soil surface of sidewalk trees and tree holes on municipal sidewalks, tree hole covers have a history of decades in urban areas. Covering the bare soil surface of conventional tree holes (1500×1250mm), it mainly plays an active role in dust prevention and ash suppression, leveling and soil stabilization, and beautifying the city appearance. [0003] Generally speaking, the cover plate made of cast iron can better meet the requirements of tree hole coverage of street trees, which is not only flat and beautiful, but also resistant to rolling. However, cast iron materials involve cast iron resources, which are often used by waste pickers for other purposes, and cannot play the role of cover plates: more than 40...

AI Technical Summary

Problems solved by technology

However, cast iron materials involve cast iron resources, which are often used by scavengers for other purposes, and cannot play the role of cover plates: more than 400 sets of cast iron cover plates were laid along the road section, but all were taken away within three days

In order to prevent theft, consider using alternative materials such as plastic, but the plastic cover plate is easily deformed and not pressure-resistant, and the production of this material will also pollute the environment; if concrete is used, it will be directly laid on the bare soil in the process , but the surface layer of the cover plate is easy to be old and damaged, the flatness and stability are poor, the service life is short, and the appearance is simple and unsightly
