Embodiment 1

[0018] Embodiment 1: the processing method of tunnel pillar, comprises the following steps:

[0019] (1) Material cutting: cut off the crooked ends formed when the roots of the original bamboo are harvested;

[0020] (2) Slicing and thread pressing: Cut the broken bamboo tube into thin bamboo slices, and then layer them. The sliced ​​bamboo slices are pressed into bamboo silk, but the bamboo silk fibers are not broken;

[0021] (3) Cooking: Cook for 28-32 hours, control the cooking temperature at 425-435°C, and then dry until the moisture content of the bamboo shreds should be controlled below 10%; the above cooking-drying process is repeated 3 times;

[0022] (4) Glue dipping: put the dried bamboo silk in an iron cage, and forcefully put it into the glue pool filled with the prepared glue solution. The bamboo threads are all immersed in the glue solution. The glue solution composition: sodium hydroxide: 9- 11%, formaldehyde: 9-11%, phenol: 58-62%, water: 18-22%, let the bamb...

Abstract

The invention discloses a processing method for tunnel pillars, which is mainly obtained through material cutting, sheet cutting, wire pressing, dipping, drying, charging, pressing, curing and anticorrosion processes in sequence. The present invention fills the drawback of no bamboo tunnel pillars in the domestic market, and can be processed to 4m; meanwhile, the present invention is energy-saving and environment-friendly, effectively reducing environmental pollution.

Description

technical field [0001] The invention relates to a processing method for tunnel pillars. Background technique [0002] At present, a large number of tunnel pillars are required in these various industries, and their production and processing methods are also varied, but most of them have high production costs, and there are no bamboo tunnel pillars at present. It is easy to cause environmental pollution in the production and processing methods. Contents of the invention [0003] In order to alleviate the deficiencies and defects of the prior art, the object of the present invention is to provide a method for processing tunnel pillars. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A processing method for tunnel pillars, comprising the following steps: [0006] (1) Material cutting: cut off the crooked ends formed when the roots of the original bamboo are harvested; [0007] (2) Slicing and thread...
