Description

[0001]
[Industrial application fields]
The present invention relates to a method for forming a fibrous connecting material for a greening base material and a slope greening method using the greening base material containing the fibrous connecting material.
[0002]
[Prior art]
The present applicant has previously described a vegetation base crack prevention method (Japanese Patent Application No. Hei 6-117709, “Japanese Patent Application Laid-Open No. 7-300857”), a method for manufacturing a greening base material, and a slope greening method using the base material (special feature). No. 7-287912 “Japanese Patent Laid-Open No. 9-103192”) was provided. In these applications, tethers and thinnings with a maximum grain size of about 1.5 mm, which are made by crushing or shredding plant wastes such as straw and vines generated from twigs and leaf crops pruned from roadside trees, wind fallen trees, bark, pruning Sadae, construction waste, maximum 20mm or less fine chips made by crushing wood waste timber end piece or the like called Kenta is utilized.
[0003]
[Problems to be solved by the invention]
However, the material consisting of these shapes ensures a void in the fermentation of organic sludge, promotes the fermentation rate, or is effective in adjusting the particle size, air permeability and water retention when sprayed. However, it was never an ideal shape that could be satisfactorily satisfied with respect to prevention of cracking due to drying shrinkage of the greening base layer after spraying and prevention of sliding. In other words, the connecting material, the fine chip, and the like are allowed to be finely pulverized enough to pass through the diameter of the spray nozzle, and have a relatively fine-grained / shortened shape, It was not sufficient for the role of a binder for preventing slipping due to the occurrence of cracks. Therefore, there was a risk that the greening basement layer would run out during torrential rain.
[0004]
[Means for Solving the Problems]
Therefore, the present invention provides a method for improving the conventional method of shredding plant wastes and wood waste materials into a maximum particle size of about 20 mm or less with a known wood crushing machine. The first aspect of the present invention is a method for forming a fibrous binder for a greening base material. After roughly crushing plant waste material with a primary crusher for wood, it is put into a crushing part of a crusher, and outer crushing teeth and inner crushing While the plant waste material is crushed by the rotation of the teeth, the protoplasm is formed into a length of about 100 mm or less and a thickness of about 5 mm or less.
[0005]
In the second aspect of the present invention, in the slope greening method using the greening base material containing the fibrous connecting material for the greening base material, the plant waste material is roughly crushed by the primary crusher for wood, and then the crusher of the crusher The protoplasm is roughly 100 mm or less in length and 5 mm or less in thickness, while the plant waste material is crushed by rotating the outer crushing teeth and the inner crushing teeth. In addition, after adding the above-mentioned binder to the incineration ash of the pulp koji and the liquid product wood vinegar obtained from smoke during the carbonization and the woody fine chips or waste sawdust, etc. After kneading the compost obtained through the fermentation decomposition process, the mixed base material mixed with the konjac flying powder and the coating fertilizer and seeds are added to the mortar spraying machine, and the nozzle is jetted by the compressed air of the compressor Time Reluctant mixed with water, is obtained by the blown so that the greening base layer of predetermined thickness of the plants slope.

[Specific process examples]
Next, a specific construction example based on the embodiment of the present invention will be described.
(1) “Molding of fibrous binder”
A plant waste material W made of felled trees, root stocks, pruned branches, cut grass, thinned wood, driftwood, fallen trees, etc. is put into a known primary crusher 3 of a large chipper type and roughly crushed to a length of about 45 cm. Next, the roughly crushed plant waste material is put into a crusher 4 and is crushed by rotation of the outer crushed teeth and inner crushed teeth to be processed into a length of about 100 mm and a thickness of about 5 mm to form a fibrous binder 5. To do.
(2) “Formation of greening basement layer”
The blending ratio of the spray material in the spray thickness 10 cm on the slope 1 and the spray area 100 m ² is as follows. 4m ³ of fibrous binder 5 made of vegetable waste, 10m ³ of organic sludge 6 as a greening base material, 7m ³ of incinerated ash 7 of pulp lees , 40kg of wood vinegar 8 and woody fine chips or the amount 3m ³ of the waste sawdust 5 'heated by introducing a fermentation machine 9, and crosscut to produce compost 10 through the fermentation decomposition processes such as aeration by. Next, a mixed base material 14 is produced by adding 270 kg of the amount of flying powder 11 generated during refining of konjac, seeds 12 for greening, and coating fertilizer 13 to the compost 10 described above. Subsequently, the mixed base material 14 is put into a mortar spraying machine 15, and sprayed onto the slope 1 while adding and mixing water when sprayed by the nozzle 17 by the compressed air of the compressor 19 to form the greening base layer 2.
[0008]
【The invention's effect】
Since the present invention has the above-described configuration, greening can be performed more than before by finishing the protoplasm into a fibrous connecting material having a length of about 100 mm or less and about 5 mm or less while crushing a new plant waste material. The effect of preventing cracks in the base layer was ensured. In addition, this fibrous connecting material is a fiber of a certain length, but since it has flexibility, it can be sufficiently blown out from the nozzle for spraying, and a conventionally used fine chip, etc. It has the effect of improving the water retention and breathability of the greening base as well as the above, and in addition to preventing the occurrence of cracks, it can fully exhibit the effect of preventing sliding. Furthermore, this fibrous connecting material can be expected to have the same effect as that of the method used in the past construction of earthen walls.
