Support conversion construction method for dewatering well drainage pipeline in super-thick raft
The invention discloses a bracket conversion construction method for dewatering well drainage pipelines in an ultra-thick raft, which comprises the following steps: S1, constructing all required dewatering wells, erecting a steel pipe temporary bracket on a pile head of a cast-in-place pile, and erecting the dewatering and drainage pipelines; s2, after the dewatering and drainage pipeline is erected, a dewatering well is used for pumping water, and excavation work of soil between raft piles is carried out; s3, after excavation of the soil between the piles is completed, the steel pipe temporary support is converted into a dewatering well channel steel support, and the dewatering well channel steel support is erected; s4, after the precipitation well channel steel support is erected, raft bottom layer steel bars and raft top layer steel bars are bound; and S5, after raft reinforcing steel bars are bound, the upper portion of the dewatering well channel steel support is cut, and raft mass concrete pouring is conducted after the upper portion of the dewatering well channel steel support is cut. According to the construction method, the construction problem that the super-thick raft reinforcing steel bars and the downcast pipe are crisscrossed in the binding process can be effectively solved, and the steel bar paying-off and binding accuracy is effectively improved.
本发明公开了一种用于超厚筏板内降水井排水管道的支架转换施工方法，包括如下步骤：S1.施工所需全部降水井，并在灌注桩桩头上搭设钢管临时支架，并架设降排水管道；S2.降排水管道架设完毕后，利用降水井进行抽水作业，并进行筏板桩间土开挖工作；S3.待桩间土开挖完毕后，将钢管临时支架转换为降水井槽钢支架，并进行降水井槽钢支架的搭设；S4.降水井槽钢支架搭设完成后，进行筏板底层钢筋和筏板顶层钢筋的绑扎；S5.筏板钢筋绑扎完成后，切割降水井槽钢支架上部，待降水井槽钢支架上部切割完毕后进行筏板大体积混凝土浇筑。本发明的施工方法能够有效解决超厚筏板钢筋绑扎工作期间与降水管纵横交错的施工难题，有效提高钢筋放线、绑扎的精确度。
