Construction method for dismantling inner support of foundation pit
The invention discloses a construction method for dismantling an inner support of a foundation pit. The inner support of the foundation pit comprises steel latticed columns, connecting beams, supporting beams, connecting plates and waist beams. The dismantling construction method for the inner support of the foundation pit comprises the following steps that S1, when construction of a basement structure in the foundation pit is completed and the condition of dismantling the inner support is met, a force transmission plate is arranged between an outer wall of the basement structure and a support pile; s2, after the force transmission plate meets the preset strength requirement, I-shaped steel is cut according to the sizes of a post-cast strip and a reserved hole on the basement structure to manufacture a profile steel support, and support connection of notch parts on the basement structure is completed; s3, a steel pipe supporting system is arranged on the bottom side of each beam body structure of the foundation pit inner support, cutting line division of each transverse supporting component of the inner support is completed, each transverse supporting component is cut, and transfer of each transverse supporting component cutting block of the inner support is completed through a tower crane; and S4, dismantling of the steel latticed column is completed, and therefore dismantling and replacing of the inner support of the foundation pit are achieved.
本发明公开了一种基坑内支撑拆除施工方法，所述基坑内支撑包括：钢格构柱、连系梁、支撑梁、连接板和腰梁；所述基坑内支撑拆除施工方法包括如下步骤：S1：待基坑内地下室结构施工完成，并满足拆除内支撑条件时，于地下室结构外墙与支护桩之间设置传力板；S2：待传力板达到预设强度要求后，根据地下室结构上后浇带及预留孔洞尺寸切割工字钢制作型钢支撑，完成地下室结构上各缺口部的支撑连接；S3：于基坑内支撑各梁体结构底侧设置钢管支撑体系，并完成内支撑各横向支撑构件的切割线划分，并进行各横向支撑构件切割，通过塔吊完成内支撑各各横向支撑构件切割块转运；S4：完成对钢格构柱的拆除，从而实现了基坑的内支撑拆除及换撑作业。
