桥梁高墩集成式造墩机设计与结构分析

The Design and Structural Analysis of Integrated Pier Building Machine for Bridge High Piers

山区桥梁及大跨度桥梁广泛存在高墩建造需求。文章所述的高墩集成式造墩机是兼物料垂直运输和人员施工作业平台功能的自动化新装备,可整体自升降,集成吊装设备,解决塔吊装拆复杂、周转期长、经济效益低的难题。文章介绍了该高墩集成式造墩机的整体设计,分析阐述了其相对传统施工方法的技术改进及应用优势,最后对造墩机主体结构受力进行了有限元模拟分析,阐述了一阶弹性稳定分析方法在该项目中的适用性。

There is a widespread demand for high pier construction in bridges in mountainous areas and largespan bridges.The high pier integrated pier building machine described in this paper is a new automatic equipment with the functions of material vertical transportation and personnel construction operation platform.It can lift itself as a whole and integrate hoisting equipment to solve the problems of complex tower crane installation and removal,long turnover period and low economic benefits.This paper introduces the overall design of high pier integrated pier building machine,analyzes and expounds its technical improvement and application advantages compared with the traditional construction method.Finally,the finite element simulation analysis is carried out on the stress of the main structure of pier building machine,and the applicability of the first-order elastic stability analysis method in the project is expounded.
