Method for repairing tree hole by manufacturing plastic thermal expansion bucket through moving type extruder and pouring cement

Abstract

Disclosed is a method for repairing a tree hole by manufacturing a plastic thermal expansion bucket through a moving type extruder and pouring cement. The extruder is moved to a site, and the manufactured plastic thermal expansion bucket is put into the tree hole immediately; the wall of the thermal expansion bucket is blown to be heated through a hot air gun while the thermal expansion bucket is hot; the bucket wall expands when heated so as to be closely attached to the hole wall of the tree hole; metal tie bars and fixing screws are arranged in the cracked tree hole; the cement is poured in the bucket; after the cement is dried, a bucket opening is covered by a plastic plate; the hot air gun is used to blow the bucket edge and the plastic plate to melt and laminate the bucket edge and the plastic plate together; the cement plays a role in repairing and supporting; the tie bars tighten a circle of a trunk to be together to enable the trunk to be a whole trunk; plastic covers the cement so that the cement cannot absorb and evaporate water and conduct chemical reaction, and accordingly the tree hole is repaired by the cement; the plastic bucket wall does not affect growing of a tree; and wood pieces are additionally pasted on the opening-sealed plastic plate, the wood pieces are beneficial for growing and healing of bark, and finally the bark covers the plastic thermal expansion bucket and cement in a tree core to enable the big tree to be integral and grow normally.

Description

[0001] The invention belongs to the fields of maintenance and management of urban forest growth, treatment of diseased trees and plastic extruder industry. Background technique [0002] Street trees, square trees, and garden trees have become the favorites of passers-by and leisure people, especially the bigger trees, trees with more shade in summer, and commemorative old trees are more popular. The lifespan of trees is very long. Among the greening plants in the city, the lifespan of trees is the longest. People especially like big trees. The bigger trees and older trees are more popular. Big trees and ancient trees have scientific value, Ecological economic value, cultural value, aesthetic value, national and local governments have also issued laws and regulations to protect. The most trees in the city are street trees. Street trees are planted in urban streets or high-grade highways if conditions permit, but urban trees are protected. There are three kinds of damages: one i...

The lifespan of trees is very long. Among the greening plants in the city, the lifespan of trees is the longest. People especially like big trees. The bigger trees and older trees are more popular. Big trees and ancient trees have scientific value, Ecological economic value, cultural value, aesthetic value, national and local governments have also issued laws and regulations to protect. The most trees in the city are street trees. Street trees are planted in urban streets or high-grade highways if conditions permit, but urban trees are protected. There are three kinds of damages: one is the man-made damage to the tree trunk, the street tree suffers the most man-made damage, and the most damaged part is the bark of the trunk which is quite high as a person. Collisions, collisions with equipment, (trees in other places suffer little damage, and almost none in forests). At present, there are no remedial measures. Street trees basically rely on their own growth and self-repair. After many trees are seriously injured, the bark cannot grow. Close up, the woody part of the trunk that loses the protection of the bark begins to rot over the years, and the trunk of some trees rots into a hollow, and the serious big tree dies

Second, trees are also harmed by insect pests, especially street trees and lively square trees. Because of the bustle of people, there are almost no natural enemies of insect pests. Tree pests in cities are completely managed by greening personnel. Once management is interrupted or negligent, serious insect pests are also endangered. In the growth of trees, people often find that the big tree is infested by insects, the trunk and branches have been eaten by insects, and even the strong wind has broken the trunk or branches, and only then can they see that the broken part is eaten by insects. When people find pests, they also spray pesticides to kill the pests, and there is nothing to do with the hollowed trunks

Third, improper maintenance and repair of branches, which cause the most hollows in big trees. When the big branches are broken by the wind in disaster weather, there are also artificial breaks, and the dead branches that are naturally eliminated at the bottom of the crown of the big tree are not repaired in time. , clean up the broken branches neatly, and let them go, causing the bark at the broken branches to not grow tightly together. After a long time, the core of the branches begins to rot here, and rots all the way to the center of the trunk; The branches were dead long ago, but they didn’t fall off, and the bark couldn’t grow tight, so it started to rot from the dead branches all the way to the center of the big trunk.

[0009] The Office of the National Afforestation Committee compiled a book, "Old and Famous Tree Rejuvenation Maintenance Technology and Protection Management Measures", which included "Old and Famous Tree Protection and Rejuvenation Technology" and four cities including Beijing, Shanghai, Tianjin, and Wuhan. The rules and regulations on the protection and maintenance technology of ancient trees all have regulations on the restoration of tree holes, but none of them proposes to isolate the additives put into the tree holes, nor does it give methods and requirements for the healing of bark growth
