specific Embodiment approach 1
[0022] Specific implementation mode one: the following combination figure 1 This embodiment will be specifically described. Concrete sleepers use bamboo and wood composite height-adjusting pads under rails, which include a core layer 1, an upper bamboo curtain surface layer 2 and a lower bamboo curtain surface layer 3, and the two sides of the core layer 1 are glued with the upper bamboo curtain surface layer 2 and the lower bamboo curtain surface layer 3 respectively.
[0023] The core layer 1 described in this embodiment is made of veneer material with high density. Fraxinus mandshurica, larch or birch has the characteristics of hard wood, small deformation, small compression ratio, and easy gluing, which can ensure that the technical specifications are consistent with the backing plate. The density requirement is used as the material for producing the core layer 1;
[0024] The upper bamboo curtain surface layer 2 and the lower bamboo curtain surface layer 3 are made of ba...
specific Embodiment approach 2
[0030] Specific embodiment two: the difference between this embodiment and specific embodiment one is: the bamboo curtain surface layer 2 and the lower bamboo curtain surface layer 3 are made of bamboo strips, and the thickness of the bamboo strips is 0.5mm, the allowable tolerance range is ±0.1mm, bamboo strips are used in the horizontal direction, cotton threads are used in the vertical direction, and the interval between two adjacent cotton threads is 100-200mm.
specific Embodiment approach 3
[0031] Specific implementation mode three: the following combination figure 2 This embodiment will be specifically described. The difference between this embodiment and the second embodiment is that: the height-adjusting backing plate is based on the required thickness of the backing plate, and the core layer 1 is assembled from N layers of high-density wooden veneers 1-1. glued together, where N is 1 or 3.
[0032] In this embodiment, when the thickness of the height-adjusting backing plate is 2 to 3 mm, the upper bamboo curtain surface layer 2 and the lower bamboo curtain surface layer 3 are made of bamboo-yellow bamboo strips, and the number of layers of the core layer 1 is Odd-numbered layers, based on the thickness requirements of the heightening backing plate, the number of layers of the core layer 1 is 1 layer or 3 layers.
