A modern arched bamboo bridge and its construction method

Abstract

The invention discloses a modern arch type bamboo bridge. The modern arch type bamboo bridge is characterized by comprising bamboo arch ribs, bamboo beams, diagonal bracings, bamboo panels and steel shoes, wherein the bamboo arch ribs, the bamboo beams, the diagonal bracings and the bamboo panels are made of reconsolidated bamboo materials; the steel shoes are made of steel materials. The invention further discloses a construction method of the modern arch type bamboo bridge. The construction method of the modern arch type bamboo bridge is characterized in that the bamboo arch ribs, the bamboo beams, the diagonal bracings, the bamboo panels and the steel shoes are prefabricated, installation of the steel shoes and a bridge abutment skewback is finished, then installation of the bamboo arch ribs and the steel shoes is finished, the bridge abutment skewback is poured, and finally the bamboo beams, the diagonal bracings and the bamboo panels are installed. The construction method of the modern arch type bamboo bridge has the advantages that the manufacturing process is simple, the cost is low, factorization and standardization of structural components are good, the assembly degree is high, the building time is short, the structural intensity is high, rigidity is large, ductility is good, and the seismic performance is good, and the obtained arch type bamboo bridge has the effects of being environmentally friendly and low in carbon.

Description

technical field [0001] The invention relates to the technical field of bridge structures, in particular to a bamboo arch bridge suitable for modern pedestrians, landscapes and assemblies and a construction method thereof. Background technique [0002] Recombined bamboo, also known as heavy bamboo, is a new bamboo material that reorganizes and strengthens bamboo. A profile made of blanks and pressure glued together. It has the advantages of low density, high strength, good toughness and good shock resistance. Under the background of the major theme of "sustainable development" in today's international society, "recombined bamboo" has become a modern and new green building material that replaces high-pollution and high-energy-consuming materials such as steel and concrete. my country is very rich in bamboo resources, known as the "Second Forest", and is the main bamboo-producing country in the world. [0003] Arch bridge refers to the bridge with arch as the main load-beari...

AI Technical Summary

Problems solved by technology

[0004] (1) Reinforced concrete bridges are self-heavy, the construction and maintenance time is long, and the durability is poor;

[0005] (2) Steel bridges are expensive, easy to corrode, and high maintenance costs in the later stage;

[0006] (3) Masonry bridges lack high-strength stones, and mining will damage the ecological environment, resulting in high costs and greater impact by floods;

[0007] (4) Wooden bridges, whose wood has a long growth cycle, is prone to decay and insects, and logging is contrary to environmental protection;

[0008] (5) Concrete and steel are industrial products with high energy consumption and high pollution, and cannot be recycled and are not environmentally friendly
