摘要
亭子口灌区一期工程第Ⅲ标项目全渠线地貌起伏较大,坡陡谷深,共设置高大渡槽7座,其支撑体系为双端圆弧渐变空心墩。针对这一特点,笔者以高效模板系统与周转使用的施工技术为研究对象,利用标准段液压爬模系统匹配更换双端半圆模板实现渐变爬升,通过若干个相邻槽墩组合成有限单元,在各单元间组织先高后低周转使用液压爬模系统进行流水作业的过程。该施工技术在桐子坝渡槽槽墩施工中得到了成功的应用,取得了较好的效果。
The third bid of Tingzikou Irrigation Area Fase I has a large undulating topography,steep slope and deep valleys.A total of 7 large aqueducts are set up,and the support system is double-ended circular arc gradient hollow pier.In view of this feature,the construction technology of high-efficiency formwork system and turnover use is taken as the research object,and the standard section hydraulic climbing formwork system is used to match and replace the double-ended semi-circular formwork to achieve gradual climbing.The finite element is composed of several adjacent trough piers,and the hydraulic climbing formwork system is used for flow-through operation in the organization of high and low turnover between units.This construction technology has been successfully applied in the construction of Tongziba aqueduct pier,and good results have been achieved.
