Large Diameter Prestressed Bridge Plastic Bellows

The characteristics of plastic bellows require high strength and flexibility of raw materials, so that the produced pipes can meet the national standard. Due to their early involvement in the field, technology, production capacity and services are relatively mature. The supply of raw materials for corrugated pipes accounts for the main field, and the supply of raw materials involves the whole country.

Application

In the actual construction of bridge plastic corrugated pipes, due to the influence of various factors, there will be different degrees of wear of bridge plastic corrugated pipes. In this regard, it is necessary to strictly control the size and position of bridge plastic corrugated pipes to improve the smoothness of the holes. degree to avoid slurry leakage at the position of the duct joints.

In the bridge construction, the bridge plastic bellows construction technology is adopted. For the connection position of the bridge plastic bellows, the tape winding and sealing method is adopted to prevent the cement slurry from entering the bellows.

The bridge plastic bellows adopts the tensioning construction method at both ends, which can be divided into two forms: tensioning in the positive bending moment area and tensioning in the negative bending moment area. When the structural strength of the beam meets the engineering design requirements, the prestressing construction can be carried out. Before the prestressed tendons enter the site, quality inspection is required, and the construction can be carried out only after passing the test.
