The present invention discloses an assembled bamboo sleeper, which is obtained by using a bamboo unit as a raw material, dried and modified at the temperature of 110-180° C., undergone coating treatment using a dopamine solution, adhesive dipping, curing and solidifying, assembling and gluing, further solidifying, further treatment using a dopamine solution, and anti-mildew and/or anti-corrosion and/or anti-insect treatment, and then fastened. The present invention further provides a preparation method for the foregoing bamboo sleeper. The bamboo sleeper prepared in the present invention is green and environmentally friendly, and applicable for ballasted tracks of railways and urban rail transit systems.

Assembled bamboo sleeper and preparation method thereof

The present invention discloses a one-step integrally-formed bamboo sleeper. For the one-step integrally-formed bamboo sleeper, a bamboo unit is used as a raw material, to be dried and modified at the temperature of 110-180° C., and then subject to adhesive dipping, adhesive throwing, solidification, dopamine solution treatment, anti-mildew and/or anti-corrosion and/or anti-insect treatment, and fastening, to obtain the one-step integrally-formed bamboo sleeper with a density of 0.9-1.5 g/cm. The present invention further provides a preparation method for the foregoing bamboo sleeper. The bamboo sleeper prepared in the present invention has a suitable elastic modulus, and applicable for ballasted tracks of railways and urban rail transit systems.

One-step integrally-formed bamboo sleeper and preparation method thereof

The invention discloses a bamboo chip integrated material. The bamboo chip integrated material is formed by a plurality of lengthened bamboo chips which are glued and overlaid; each lengthened bamboo chip is formed by a plurality of bamboo chip units which sequentially and continuously mesh and are butted; sharp teeth and grooves are formed in the two ends in the length direction of the bamboo chip units, wherein the sharp tooth of each bamboo chip unit and the groove of the corresponding bamboo sheet unit are matched to form a meshing butt-joint part, and the meshing butt-joint parts of the adjacent lengthened bamboo chips are arranged in a staggered mode; and each bamboo chip unit has a thickness of 4-12 mm and a width of 15-50 mm.
