A hollow bamboo strip includes mao bamboo sheets formed by splitting bamboo; the two sides of a mao bamboo sheet are cut with matching surfaces, thereby making a finished bamboo sheet with a trapezoidal cross section, the matching surfaces of a plurality of finished bamboo sheets are successively spliced or finger jointed into a hollow bamboo strip with a hollow structure. A hollow bamboo board is spliced by fitting several hollow bamboo strips at side surfaces. A method for manufacturing a hollow bamboo board includes: splitting the bamboo into several mao bamboo sheets in its peripheral direction; cutting a mao bamboo sheet into a finished bamboo sheet with a trapezoidal cross section; carbonizing the finished bamboo sheet; forming the finished bamboo sheets subjected to carbonization into a hollow bamboo strip; fitting corresponding side surfaces of several hollow bamboo strips to be spliced into a hollow bamboo board.

A disclosed press 100 may flatten halved bamboo stalks or other workpieces without loss of volume or splintering. In a first mechanical movement executed by a pushrod drive train 300, a plurality of spreader bar assemblies 370 press upon the centerline of a workpiece such that the workpiece does not move off of a work surface but is yet not over crushed. Each spreader bar assembly may comprise two spreader bars 350 hingedly attached to a pushrod 345. The lower end of the pushrod and proximal ends 363 of the spreader bars pin down the workpiece. In a second mechanical movement executed by a crusher bar drive train 400, the distal ends of the spreader bars are moved outwardly and spread apart the curved walls of the workpiece. In the last phases of a second movement, planar track plates 440 press downwardly upon the workpiece.

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.sup.3. 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.

A bamboo splitter has an outer support ring with an interior mounted inner ring blade. A plurality of base blades are radially arranged around the inner ring blade and both the inner ring blade and the base blades have v-shaped cutting surfaces. Attached to each base blade is a pair of slat blades that attach to the base blades at a vertex and have a left and right slat blade. The angle between the vertex and the left and right blades is chosen so that adjacent left slat blades are parallel to adjacent right slat blade forming a parallel cutting space which produces bamboo slats that have orthogonal edges which makes them much more amenable to traditional building methods. A different number of slat blades may be used depending on the size of the bamboo being used and the size and number of the slats being produced.

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.

A computerized reed fabrication system having an X-Y-Z axes computer numerical controlled (CNC) machine capable of holding a tool bit. The CNC machine operates under the control of CNC software commands. The reed fabrication system further includes a tool bit held by the CNC machine and a reed holder located adjacent that tool bit. Non-transitory computer readable media stores CNC software commands. A computer reads those stored CNC software commands and sends them to the CNC machine. The CNC software commands cause the CNC machine to move the tool bit relative to the reed holder as required to fabricate a double reed from a cut piece of reed cane.
