Abstract
The invention discloses a processing method of an underground tunnel supporting column. The underground tunnel supporting column is obtained mainly by cutoff process, bamboo chip forming process, bamboo filament pressing process, gumming process, drying process, loading process, pressing process, solidifying process and anti-corroding process. The processing method of the underground tunnel supporting column overcomes shortcomings that bamboo underground tunnel supporting columns do not exist on the domestic market, and the underground tunnel supporting column can be processed to 4 m; and simultaneously, energy is saved, the environment is protected, and environmental pollution is effectively reduced.
Description
Technical field
The present invention relates to a kind of processing method of pitprop.
Background technology
At present, the equal a large amount of pitprop of demand in this multiple industry, its production and processing method is also varied; But most cost of production is high, and does not have bamboo pitprop now, and general ore pillar length is at 2m; Length is short, in production and processing method, causes environment pollution simultaneously easily.
Summary of the invention
For deficiency and the defective of alleviating prior art, the object of the present invention is to provide a kind of processing method of pitprop.
The present invention adopts following technical scheme to achieve these goals:
The processing method of pitprop may further comprise the steps:
(1), fracture: clip the crooked termination that forms when former bamboo root is felled;
(2), hack, silk pressing: the thick bamboo tube behind the fracture is split into thin bamboo plate again, layering then, the bamboo chip after hacking is pressed into the bamboo silk, but the bamboo silk that bamboo filament fibre does not rupture;
(3), boiling: carried out boiling 28-32 hour, the control boiling temperature is 425-435 ℃, again should be below 10% through the moisture Control that is dried to the bamboo silk; Above process repeated multiple times;
(4), impregnation: the bamboo silk that drying is crossed is placed in the iron cage, forces to put into to fill the glue pond that modulates glue, and the bamboo silk all immerses glue; Glue composition: NaOH: 9-11%, formaldehyde: 9-11%, phenol: 58-62%; Water: 18-22%; Let the bamboo silk fully soak into, soak time is about 20 minutes, mentions the iron cage then and is placed on the dried unnecessary glue of drench on the glue pool side;
(5), drying: again the bamboo silk behind the impregnation is dried to moisture below 10%;
(6), charging, press: the bamboo silk is placed in the charger of press and delivers in the hopper of press; Under 3000-6000t pressure; Force the bamboo silk to be expressed in the U type die, will be out of shape the bamboo silk with cover plate and iron pin then and be locked in the mould, lock with bolt again after pulling out press;
(7), curing, anticorrosion: the bamboo silk square stock that suppresses is cured in mould, in mould, takes out then, and carries out preservative treatment, the final head warehouse-in of cutting out.
The processing method of reorganization bamboo, curing can adopt continous way drying room, fixed drying room, Steam Heating, fuel Heating or electrical heating to solidify in the described step (7).
Described glue composition: NaOH: 10%, formaldehyde: 10%, phenol: 60%, water: 20%.
Digestion process repeats repeatedly, can not have under the situation of charing, and bamboo wood can not be out of shape after solidifying.Its stress is fully discharged.
Advantage of the present invention: 1, the domestic market does not have bamboo pitprop now; 2, length: general ore pillar length is at 2m, and this technology can be machined to 4m; 3, remove carbonization technique, effectively reduced environment pollution.

The specific embodiment
Embodiment 1: the processing method of pitprop may further comprise the steps:
(1), fracture: clip the crooked termination that forms when former bamboo root is felled;
(2), hack, silk pressing: the thick bamboo tube behind the fracture is split into thin bamboo plate again, layering then, the bamboo chip after hacking is pressed into the bamboo silk, but the bamboo silk that bamboo filament fibre does not rupture;
(3), boiling: carried out boiling 28-32 hour, the control boiling temperature is 425-435 ℃, again should be below 10% through the moisture Control that is dried to the bamboo silk; Above boiling-dry run 3 times repeatedly;
(4), impregnation: the bamboo silk that drying is crossed is placed in the iron cage, forces to put into to fill the glue pond that modulates glue, and the bamboo silk all immerses glue; Glue composition: NaOH: 9-11%, formaldehyde: 9-11%, phenol: 58-62%; Water: 18-22%; Let the bamboo silk fully soak into, soak time is about 20 minutes, mentions the iron cage then and is placed on the dried unnecessary glue of drench on the glue pool side;
(5), drying: again the bamboo silk behind the impregnation is dried to moisture below 10%;
(6), charging, press: the bamboo silk is placed in the charger of press and delivers in the hopper of press; Under 3000-6000t pressure; Force the bamboo silk to be expressed in the U type die, will be out of shape the bamboo silk with cover plate and iron pin then and be locked in the mould, lock with bolt again after pulling out press;
(7), curing, anticorrosion: the bamboo silk square stock that suppresses is cured in mould, in mould, takes out then, and carries out preservative treatment, the final head warehouse-in of cutting out.
The processing method of reorganization bamboo, curing can adopt continous way drying room, fixed drying room, Steam Heating, fuel Heating or electrical heating to solidify in the described step (7).
Described glue composition: NaOH: 10%, formaldehyde: 10%, phenol: 60%, water: 20%.
The density of the pitprop that the present invention produces is 0.8-1.6, can be 50 years service time.
