Thin-wall hollow pier EPS core mold construction technology
The invention relates to the technical field of hollow pier construction, in particular to a thin-wall hollow pier EPS core mold construction technology which comprises the steps that a bearing platform foundation pit of a thin-wall hollow pier is excavated and determined as a roadbed working area, embedded pier body steel bars are bound and fixed, an EPS core mold is installed on the inner wall of the side, close to the inner mold set, of an inner mold set, and the thin-wall hollow pier is constructed; a supporting plate and a supporting rod which are parallel to the inner module are installed in the inner module, a plurality of supporting pieces which are fixedly bound with the steel bars are installed on the top of the inner module, concrete is poured into the inner space surrounded by the modules, concrete is poured on the outer formwork for solid capping, and the thin-wall hollow pier is manufactured after capping is completed. According to the thin-wall hollow pier EPS core mold construction technology, the EPS core mold which is small in density, excellent in buffering performance, good in mechanical performance, good in chemical stability, excellent in processing performance, excellent in heat insulation and sound insulation performance and good in water stability is adopted, in the construction process, the influence of sunlight temperature on deviation of a pier is considered, a construction section is correspondingly adjusted, and the construction efficiency is improved. And the anti-cracking steel bars are reasonably arranged or corresponding temperature control measures are taken.
本发明涉及空芯墩施工技术领域，尤其涉及了一种薄壁空芯墩EPS芯模施工工艺，开挖薄壁空心墩的承台基坑，确定为路基工作区，对预埋的墩身钢筋进行绑扎固定，在内模组的靠近的一侧内壁安装EPS芯模，在内模组内安装与其平行的支撑板和支撑杆，在内模组的顶部安装有若干与钢筋绑扎固定的支撑件，对模组围绕的内部空间浇筑混凝土，在外模板上浇筑混凝土进行实体封顶，封顶结束后薄壁空心墩制成。该薄壁空芯墩EPS芯模施工工艺，采用了EPS芯模密度小、缓冲性能优、机械性能好、化学稳定性好、加工性能优异、隔热隔声性能优良、水稳定性好，在施工过程中，考虑日照温度对桥墩偏位的影响，对施工段进行相应的调整，合理布置防裂钢筋或采取相应的温控措施。
