Special-shaped section bidirectional hydraulic self-elevating type creeping formwork system and creeping formwork method thereof
The invention relates to the technical field of water conservancy and hydropower engineering construction, and provides a special-shaped section bidirectional hydraulic self-elevating type creeping formwork system and a creeping formwork method thereof. Compared with construction of an ultra-deep (high) shaft type special-shaped section mass concrete structure, the construction scheme of a slip form, an ultra-high scaffold loose form or a customized turnover form of the structure is conventionally adopted; a special-shaped-section bidirectional hydraulic self-elevating type creeping formwork method is adopted, concrete pouring slump control is facilitated, the formwork can be lifted after it is determined that concrete meets the strength requirement, the safety coefficient of formwork lifting is overall improved, and the requirement for concrete strength and formwork lifting time precision control is lowered; the operation platform is hung on the self-climbing template, so that the erection of an ultrahigh bent frame can be avoided, the number of hoisting machinery is reduced, the construction efficiency is improved to a great extent, and the economic benefit is good; each group of creeping formworks of the inner wall and the outer wall can climb independently, safety and stability in the construction process can be guaranteed, the possibility of construction accidents is reduced, and the safety coefficient is high.
本发明涉及水利水电工程施工技术领域，提出了一种异型截面双向液压自升式爬模系统及其爬模方法。相较于超深（高）井筒类异型截面大体积混凝土结构施工时，常规采取该结构滑模、超高脚手架散模或定制翻模施工方案；采用异型截面双向液压自升式爬模的方法，便于混凝土浇筑坍落度控制，经测定砼达到强度要求后方可提升模板，整体提高了模板提升的安全系数，对混凝土强度及模板提升时间精度控制的要求降低；在自爬的模板上悬挂操作平台，可避免超高排架搭设，减少起重机械数量，极大程度上提高了施工效率，经济效益好；内外墙每组爬模都可独立爬行，能够确保施工过程中的安全性和稳定性，减少施工事故发生的可能性，安全系数高。
