Bamboo sleeper assembled to be formed and preparation method thereof

Abstract

The invention discloses a bamboo sleeper assembled to be formed. The bamboo sleeper is obtained in the modes that a bamboo unit is taken as a raw material, dried and modified at 110-180 DEG C, subjected to cladding treatment through a dopamine solution, impregnated, solidified to be formed, assembled and glued, solidified again, retreated through the dopamine solution, subjected to mould-proof and / or anti-corrosion and / or insect-proof treatment, and tightened. The invention further provides a preparation method of the bamboo sleeper. The prepared bamboo sleeper is environmentally friendly andsuitable for ballast rails of railway and urban rail transit.

Description

technical field [0001] The invention relates to the field of new materials for railways and urban rail transit, in particular to an assembled bamboo sleeper and a preparation method thereof. Background technique [0002] The new type of bamboo is a characteristic bamboo product in my country that uses bamboo instead of wood and is used as a green building material for outdoor use. Through technological innovation in recent years, its production technology has become more and more mature, and the product quality has become more and more stable. In addition to being highly resistant to natural weather and biological erosion outdoors, it also has good elasticity and is more suitable for use as blanks for railway sleepers. Bamboo is rich in resources, green and sustainable, which solves the shortcomings of insufficient supply of high-quality wood for wooden sleepers, and the shortcomings of chemicals such as creosote required for anti-corrosion treatment that endanger the enviro...

AI Technical Summary

Problems solved by technology

[0003] Wooden sleepers, concrete sleepers, steel sleepers, and composite material sleepers used for ballast tracks in existing railways have the following disadvantages: for example, wooden sleepers have short service life, are easy to wear, and have different mechanical properties of different wooden sleepers, etc.; , poor insulation, high brittleness, poor elasticity, risk of impact damage, low stability, heavy weight, difficult to replace, difficult to recycle, etc.; there are also steel sleepers, no insulation, high driving noise, high rigidity, easy to rust, etc. etc.; there are also composite material sleepers, which are light in weight, have poor fastener and bolt holding ability, and are easily affected by the environment and become brittle, etc.
