Abstract

The invention provides an environment-friendly and energy-saving slope protection bamboo-wood lattice beam for a mountain highway. The environment-friendly and energy-saving slope protection bamboo-wood lattice beam is characterized in that bamboo piles and wood chips are combined so as to perform combined protection on the deep layer and shallow layer of a side slope; improved soil is used for carrying out cultivation and greening, all sections of each pile are communicated, and the embedment end of each bamboo pile is sharpened; injected holes are formed in the surface of each bamboo pile and are uniformly distributed; transverse frame beams and vertical ledger beams are made of a concrete or reinforced concrete material, and cast-in-place construction is carried out; the bamboo-wood lattice beam is of a precast assembled structure, bamboos are used as vertical bamboo bursal rays, and the wood chips form a rhombic lattice in an interlaced mode; the diameter of the vertical bamboo bursal rays 8-11cm, the wood chips between the vertical bamboo bursal rays are used as transverse wood sopports which are connected with the vertical bamboo bursal rays; the support rhombic lattice is light in weight; and the improved soil is cultivated in the lattice and consists of local soil and an improver. The environment-friendly and energy-saving slope protection bamboo-wood lattice beam has the advantages of being simple in construction, environment-friendly and energy-saving, adopting local materials and meeting the requirements of ecological side slope protection. The environment-friendly and energy-saving slope protection bamboo-wood lattice beam is suitable for various deep and shallow soil side slope greening and protecting engineering in civil engineering.
