Problems solved by technology

There are two traditional methods for filling tree holes: one is the masonry stacking method, where layers of bricks and stones are piled up, and the exterior is painted; in this method, the expansion coefficient of cement and lime is inconsistent with the change of the tree body, and it is easy to produce Cracks, water seeps into tree holes through cracks, and after the tree absorbs water, it will accelerate the decay of the tree
Another method is the watering method attached to the body. The shell board is made according to the tree body, and after the vertical steel bar is tied inside, concrete (the mixture of small gravel and cement is 3:1) or polyurethane hard foam material is poured, compacted and Molding, such a

Embodiment Construction

[0025] The present invention will be further described below in conjunction with typical embodiments.

[0026] The gradient bionic filling method of the tree cavity of the present invention, such as figure 1 As shown, the steps are as follows:

[0027] 1. Tree hole cleaning: Thoroughly remove the sundries in the tree hole, especially the rotten xylem, until healthy tissue is exposed;

[0028] 2. Tree hole disinfection: Spray or smear the inside of the tree hole with a disinfectant such as 1:15 copper sulfate aqueous solution or 5% copper quaternary ammonium (ACQ), and then perform spray disinfection on the cleaned tree hole inner wall;

[0029] 3. Preparation of slurry:

[0030] Coarse slurry: the woody unit mixed with wood fiber and wood shavings and inorganic adhesive are fully stirred and mixed according to the mass ratio of 1.5 to 2:1 (preferably 1.5:1) to form a coarse slurry; the coarse slurry It can be subdivided into semi-coarse pulp and coarser pulp;

[0031] Fine...

Abstract

The invention relates to a bionic filling method of the gradient of a tree body hole, which comprises the following steps: tree hole clearing: removing impurities in the tree hole; tree hole sterilizing: spraying or smearing the water solution of copper sulfate; slurry preparing: mixing an inorganic adhesive and a wood unit formed by mixing wood fiber and wood wool to prepare coarse slurry, and mixing the inorganic adhesive and a wood unit of wood powder to prepare fine slurry; slurry filling: respectively filling the coarse slurry and the fine slurry to the inner layer and the outer layer of the tree hole by using the central axis of the tree body as a symmetric line, and under the action of gravity, the slurry is in gradient distribution in the vertical direction of the tree hole; slurry solidifying: after the slurry is filled layer by layer, bonding the slurry with the hole wall into a whole; and simulation decorating: bonding a layer of real tree bark on the solidified filling material. Thus, the solidified filling material and the tree body filled with the filling material have the same gradient distribution rules of density and strength, thereby being more close to the flexibility of the tree body.

Description

technical field [0001] The invention relates to a gradient filling method for hollows in trees, in particular to a gradient filling method for hollows in ancient trees over a hundred years old. Background technique [0002] As we all know, trees (especially old trees over a hundred years old) grow weaker with age and growth, or due to other human factors, the xylem is easy to rot and form cavities, and some even reach the roots, forming Extra large tree hole (hollow). Due to the rot of the xylem and the influence of water, it is easy to cause the reproduction of fungi, further expand the cavity, seriously reduce the growth force and weaken the growth potential, reduce the load capacity of the trunk, and shorten the life span of the tree. If the tree hole is not filled in time, the trunk will be scraped off, and in severe cases, tourists will be injured. [0003] Tree hole filling is an important work in tree (old tree) conservation measures, and it is also an effective mea...
