Abstract

The invention provides an assembly type bamboo bridge. The assembly type bamboo bridge consists of bamboo longitudinal beams (1), bamboo transverse beams (2), bamboo panels (3), a transverse pre-stressing tendon (4) and a longitudinal pre-stressing tendon (16). All bamboos used by the assembly type bamboo bridge are soaked in a gum dipping tank which contains polyurethane resin and phenolic resin before being assembled, and boiled for 10-15 minutes at 100 DEG C-110 DEG C, wherein the volume ratio of the polyurethane resin to the phenolic resin is (2-2.5):1; and then, the bamboos are got out and dried, and a layer of waterborne polyurethane resin, a layer of polyurethane resin, a layer of waterborne polyurethane resin and a layer of resurcinolformaldehyde resin are uniformly coated on the outer surfaces of all bamboos in sequence. The assembly type bamboo bridge is large in structural strength, good in drawability, green and environment-friendly in used materials, standard in structural components, high in assembly degree, good in structural integrity, and capable of sufficiently bringing the advantages of the materials into play, and satisfying the normal use and durability needs of the bridge beam structure.

Description

[0001] technical field

[0002] The invention belongs to the technical field of bridge structures, in particular to an assembled bamboo bridge. Background technique

[0003] Under the current background of developing low-carbon economy, green, ecological, environmental protection and low-carbon new building structural materials are the inevitable direction of civil engineering technology development. The biggest advantage of bamboo is environmental protection and renewable raw materials. The period of bamboo is generally 2 to 4 years (wood takes 20 years). According to incomplete statistics, the national bamboo forest area is about 3.54 million hectares (not including Taiwan Province), accounting for about 3% of the total forest area, with a stock volume of about 80 million tons and an annual output of more than 8 million tons of bamboo. my country's bamboo species and bamboo forest area account for about 1 / 4 of the world's total, and bamboo production accounts for about 1 / ...
