Novel energy-saving bamboo bridge

Abstract

The invention provides a novel energy-saving bamboo bridge. The novel energy-saving bamboo bridge comprises longitudinal bamboo beams (1), transverse bamboo beams (2), bamboo panels (3), transverse pre-stressed trusses (4) and longitudinal pre-stressed trusses (16). A layer of waterborne polyurethane resin, a layer of polyurethane resin, a layer of waterborne polyurethane resin and a layer of resorcinol formaldehyde coat the outer surfaces of all the bamboo materials of the bamboo bridge in sequence. The bamboo bridge further comprises lighting devices and a brightness sensor, and the lighting devices are controlled to be started through the numerical value measured by the brightness sensor. The novel bamboo bridge can start the lighting device according to the brightness and save energy sources.

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 / ...
