Construction method for lightweight structure of large-span tunnel roof
The invention provides a construction method for a lightweight structure of a large-span tunnel roof. The construction method specifically comprises the following steps that S1, a formwork is installed, accepted and positioned; s2, binding and fixing plate bottom steel bars; s3, hollow pipe positioning ribs are installed; s4, laying and fixing hollow pipes; s5, anti-floating treatment measures are taken; s6, binding plate surface steel bars; s7, steel bar engineering hidden acceptance inspection; s8, concrete pouring; and S9, maintaining. By means of the technical scheme, the orthogonal isotropic hidden dense rib hollow structure is integrally formed, and the load larger than that of a structure of the same specification can be borne. The using amount of concrete and steel bars is greatly reduced, the self weight of the structure is reduced, the construction speed is increased, the construction period is shortened, and economic benefits are guaranteed. The floating condition of the pipeline is avoided, so that the phenomena of deformation, displacement and the like of the reinforcing steel bars are avoided. The thermal insulation performance of the whole concrete plate is greatly improved, the indexes of sound insulation and noise reduction are greatly improved, and the social effect is greatly improved.
本发明提供了一种大跨径地道顶板轻量化结构施工方法,具体包括以下步骤:S1、模板安装、验收、定位;S2、板底钢筋的绑扎与固定;S3、安装空心管定位筋;S4、铺设、固定空心管;S5、抗浮处理措施;S6、板面钢筋绑扎;S7、钢筋工程隐蔽验收;S8、混凝土浇筑;S9、养护。通过本发明的技术方案,整体形成正交同性暗密肋空心结构,可以承受比同规格结构更大的荷载。大幅降低了砼、钢筋用量,减少了结构自重,施工速度加快,节省了工期,经济效益得到保障。解决了管道上浮情况,从而避免钢筋变形、移位等现象的产生。整体砼板的保温性能大大提高、隔音降噪的指标大大提高,社会效果大大提高。
