Roll line slag sluice foundation pit construction method
The invention relates to the technical field of smelting engineering slag runner construction, in particular to a rolling line slag flushing runner foundation pit construction method which comprises the following steps: paying off and excavating earth; constructing a cushion layer; after the cushion layer is poured for 24 hours, side wall outer formworks and scaffolds are erected on the outer sides of the two side walls of the slag runner; after the formwork is erected, a gap between the side wall outer formwork and the groove wall is replaced and filled till the gap is replaced and filled to an equipment foundation cushion layer; after replacement and filling are conducted for 24 h, the side wall outer formworks are dismantled, meanwhile, the slag runner side wall pouring inner formworks are erected, the replacement and filling part serves as the side wall pouring outer formworks, and pouring is conducted on the side walls of the two sides of the slag runner; according to the method, no support needs to be arranged, measure materials are saved, the construction cost is reduced, and the construction progress is accelerated; a protection surface can be quickly formed, and the problems of long exposure time of gaps on the two sides and poor stability of the foundation pit are solved; and after replacement filling is completed, the slag runner side wall and the equipment foundation can be constructed at the same time, the construction period can be effectively shortened, and construction efficiency is improved.
本发明涉及冶炼工程渣沟施工技术领域，特别是涉及一种轧线冲渣沟基坑施工方法，包括如下步骤：放线及土方开挖；垫层施工；垫层浇筑24h后，在渣沟两侧壁外侧支设侧壁外模板及脚手架；模板支设完成后，进行侧壁外模板与沟槽壁间隙换填填充，直至换填到设备基础垫层；换填24h后，拆除侧壁外模板，同时支设渣沟侧壁浇筑内模板，换填部分作为侧壁浇筑外模板，进行渣沟两侧侧壁浇筑；本方法无需设置支护，节约了措施材料，减少了施工费用，加快了施工进度；能够快速形成保护面，避免了两侧间隙暴露时间长、基坑稳定性差的问题；换填完成后，渣沟侧壁与设备基础能够同时施工，进而能够有效缩短工期，提高施工效率。
