Novel prestress strand pulling device applied to segmental girder bridge and construction technology of novel prestress strand pulling device
The invention relates to a novel prestress strand pulling device applied to a segmental girder bridge, which comprises a power propulsion assembly, a through hole pretreatment assembly, a protective cap and a sphere assembly, and is characterized in that the power propulsion assembly is used for providing power for the through hole pretreatment assembly and the sphere assembly while being used for pulling a prestress steel strand; and the through hole pretreatment assembly is located and connected with the power propulsion assembly and used for conducting linear checking and inner wall cleaning on the corrugated pipe. The power propelling assembly is used for replacing a traditional power propelling device, the through hole pretreatment assembly is used for solving the problems that the steel strand penetrating space is small, the hole channel radian and line shape are not clear, and edges exist, the steel strand is prevented from being scratched through the protective cap, the steel strand can be prevented from being positioned and wound through the ball assembly, the construction speed can be remarkably increased, and the construction cost is reduced. The prestressed steel strand is prevented from being scratched and wound, the construction precision and efficiency are greatly improved, and the construction quality of the segmental beam is guaranteed.
本发明涉及一种应用于节段梁桥的新型预应力穿束装置,包括：动力推进组件、通孔预处理组件、保护帽、球体组件，所述动力推进组件用于预应力钢束穿束的同时，为所述通孔预处理组件和所述球体组件提供动力；所述通孔预处理组件位于所述动力推进组件连接，用于对波纹管线性排查及内壁清洁。本发明通过使用动力推进组件代替传统动力推进装置，使用通孔预处理组件解决钢绞线穿束空间较小、孔道弧度线形不明确、存在棱边的问题，通过保护帽防止钢绞线刮伤，并且球体组件可防止钢绞线定位及缠绕，可以显著提高施工速度，防止预应力钢绞线刮伤和缠绕，极大的提高施工精度及效率，保证节段梁施工质量。
